                      "THE BENEFITS OF TAX-FREE INVESTING"

                                                                  February, 2006

Dear Fellow Shareholder:

      As the name of your fund  clearly  states,  Tax-Free  Fund of  Colorado is
tax-free* - free from Colorado state and regular Federal income taxes.

      This tax-free status serves many purposes.  It obviously provides you, and
our  other   shareholders,   with  tax-free   income.   But,  it  also  provides
municipalities  with  an  attractive  motivator  to  help  them  raise  revenue.
Additionally,  the  projects  funded by these  tax-free  securities  enhance the
quality of life for all community residents.

      Many  individuals pay as much as 30% to 40% of their income in Federal and
state taxes.  Obviously, if you have to pay that much in taxes, it significantly
reduces what you get to keep in your pocket.

BENEFITS TO INVESTORS

      As an  investor  seeking  tax-free  income,  do you have to forego  higher
yields? Not necessarily.

                                  [BAR CHART]

                  Hypothetical Tax-Free Yield                           3%
                  Hypothetical Taxable Equivalent Yield               4.8%

                  Hypothetical Tax-Free Yield                           4%
                  Hypothetical Taxable Equivalent Yield     6.[ILLEGIBLE]%

                  Hypothetical Tax-Free Yield                           5%
                  Hypothetical Taxable Equivalent Yield     8.[ILLEGIBLE]%

                        This  chart  assumes  a  35%  federal  and  4.63%  state
                        tax-rate and is for illustration  purposes only; it does
                        not  represent   past  or  future   performance  of  any
                        investment.

      The chart above shows that you would have to earn  significantly more from
a  taxable  investment  in order  to be  equal  to what  you get to keep  from a
tax-free investment.

      As you can  clearly  see from the chart,  you would have to earn 6.5% on a
taxable investment in order to equal the tax-free level of 4%.

      Keep this  illustration  in mind the next time you  examine the yield that
Tax-Free Fund of Colorado offers you. You will find that a 3%, 4% or 5% tax-free
yield  looks   considerably  more  attractive  to  you  when  you  consider  the
implications of taxes.

BENEFITS TO MUNICIPALITIES

      As you are most likely aware, states,  counties,  cities, towns, and other
forms of  municipalities  issue  tax-free  bonds to raise  monies.  These issues
generally take two forms - general obligation securities and revenue securities.

      General  obligation  municipal  securities are primarily those  securities
used to finance the general  needs of such  municipalities.  General  obligation
securities are secured by the tax-raising power of the specific  municipality in
terms of its ability to pay  interest  and repay  principal  on a timely  basis.
Thus,  these  securities  are  considered  to be  "backed  by the full faith and
credit" of the issuer.

      Revenue  securities  are issued to finance  specific  projects,  such as a
hospital  or  airport.  In this  instance,  the  municipal  issuer  pledges  the
operating  revenues  derived from the  specific  project to pay the interest and
repay the principal when due.

      In many cases, smaller  municipalities would have difficulty selling these
securities  to the  marketplace  were  it not for the  added  attractiveness  of
tax-free status.

BENEFITS TO QUALITY OF LIFE

      The benefit you may not have considered - when you made your investment in
the Fund - was that in the process of having the Fund provide you with  tax-free
income,  it also provides help to a variety of others within your  community and
Colorado. This is a benefit in which you can take real pride.

      Municipal bonds, such as those in which Tax-Free Fund of Colorado invests,
are the primary way  infrastructure is financed.  Infrastructure is a relatively
obscure  word that by itself  doesn't mean much to most  people.  But,  when you
translate  the word  "infrastructure"  into  projects  such as  schools,  roads,
bridges, water facilities,  pollution control, airports, hospitals, and fire and
police  stations,  then  you are  speaking  in terms  that  people  more  easily
understand.

      As the economy of Colorado grows,  new and additional  municipal  projects
are  needed  for the  benefit  of the  citizens  of  Colorado  and  the  various
communities  throughout the state.  In essence,  your money invested in the Fund
helps pay for that new school,  road, airport,  etc. that you and your neighbors
now enjoy.  So, as an investor in Tax-Free Fund of Colorado,  you can take pride
in knowing  that you are playing a vital role and a very real part in  enhancing
the quality of life for your family,  friends,  neighbors and future generations
of Coloradans.

SUMMARY

      So the next time that you receive your  statement  from  Tax-Free  Fund of
Colorado,  remember that the benefits that are reaped from your  investment  are
more than just what is evident on that piece of paper.

                                   Sincerely,


/s/ Diana P. Herrmann                          /s/ Lacy B. Herrmann

                              MANAGEMENT DISCUSSION

2005 REVIEW

      The two main themes  affecting the  fixed-income  markets in 2005 were the
continuation  of short-term  interest rate increases by the Federal Reserve (the
"Fed") and a flattening of the U.S. Treasury yield curve. The Federal Funds rate
rose from 2.25% at the beginning of 2005 to 4.25% in December.  The Fed has made
it  abundantly  clear that their main  priority is to keep  inflation  in check.
While  short-term  interest rates rose by a full 2.0% during the year,  interest
rates on Treasury securities with maturities of 10 years and longer only rose by
about 0.6%, which created the "flatter" yield curve.  This is an indication that
the market has a lot of confidence  that the Federal Reserve will keep inflation
low for the  foreseeable  future.  The risks to continued low interest rates are
spiking  energy costs,  rising budget and trade  deficits,  strong labor markets
with real wage  growth and the costs of war  overseas.  We believe  that as 2006
progresses  we will  begin to see the  effects  of the Fed's  current  effort to
reduce the pace of economic growth.  If inflation  remains  contained,  consumer
spending begins to slow, and Gross Domestic Product (GDP) weakens,  shorter-term
interest rates are likely to decline.

      The Colorado  economy  continues to do well.  The Office of State Planning
and Bugeting  forecasted a 2.1%  increase in Colorado  employment  in 2005,  the
unemployment  rate remains below 5%, personal income growth was above 6% in 2005
and retail trade sales are forecast to grow 5.7%.  Construction activity in this
state has always been the wild card. During the past year,  residential has been
about flat while  non-residential  construction has risen by 8.7% led by retail,
office  and  factory  projects.  Tourism  also  remains  a strong  point for the
Colorado economy. Skier visits, hotel occupancy, conventions and airport traffic
have all shown good improvement.

      The Colorado municipal bond market experienced another busy year. Although
total issuance was down about 7% to $7 billion,  the new issue supply was steady
and of high quality.  In November,  Colorado  voters passed  Referendum C, which
will allow the state to retain all the revenue it collects  for the next 5 years
without limits.  This is expected to add $3.1 billion to state coffers over that
time  period.  We believe that this is a positive  development  for the Colorado
municipal  bond market as it will improve the credit  strength of the state as a
whole and also add some stability to the funding of many municipal projects that
the state supports. The companion ballot issue,  Referendum D, which allowed for
bonding of  transportation,  elementary  and higher  education  programs did not
pass.

      Tax-Free  Fund of  Colorado  sought to  maintain  a  defensive  investment
posture for 2005.  The average  maturity of the bonds in the Fund ended the year
at 8.2 years.  The yields on lower credit  quality  bonds  continued to compress
relative to the highest  quality  bonds.  Consequently,  we  maintained  our 98%
position in AAA & AA rated bonds. Approximately two-thirds of our portfolio



has maturities of 10 years or less.  These bonds  experienced a slight  negative
impact from rising short-term interest rates. We believe that the higher coupons
and  shorter  maturities  of these  bonds  will  serve us well in the event that
longer-term  rates rise or shorter rates return to lower levels  associated with
slower economic growth.  The total return for Class A investors based on the Net
Asset  Value  was  1.53% in 2005.  The  double-exempt  dividend  yield  averaged
approximately 3.8% for the year.

2006 STRATEGY

      We  anticipate  that  2006  will  begin  to bring  about a  change  in our
portfolio.  As some of the shorter  high  coupon  bonds  approach  call dates or
maturities we may sell them and reinvest the proceeds in the 13 to 15 year range
in an effort to improve  yield.  In the event that  shorter-term  interest rates
begin  to  decline  faster  than  long-term  interest  rates,  we will  have the
flexibility to accelerate this process. We are also prepared to improve yield on
the Fund by adding selected A rated  securities once the yields improve relative
to AAA rated bonds. We will continue to maintain our overall portfolio  strategy
of intermediate  maturity,  investment-grade  securities  while we are trying to
improve yield within those parameters. We appreciate your investment in Tax-Free
Fund of Colorado and we place the highest  priority on providing a safe,  stable
double tax-exempt income stream with low share price volatility.



PERFORMANCE REPORT

      The following graph illustrates the value of $10,000 invested in the Class
A shares of Tax-Free Fund of Colorado for the 10-year  period ended December 31,
2005 as compared with the Lehman Brothers  Quality  Intermediate  Municipal Bond
Index and the Consumer Price Index (a cost of living index).  The performance of
each of the other classes is not shown in the graph but is included in the table
below.  It should be noted that the Lehman Index does not include any  operating
expenses nor sales charges and being nationally oriented, does not reflect state
specific bond market performance.

Total return  figures  shown for the Fund reflect any change in price and assume
all distributions within the period were invested in additional shares.  Returns
for Class A shares are calculated  with and without the effect of the initial 4%
maximum sales charge. Returns for Class C shares are calculated with and without
the  effect  of the 1%  contingent  deferred  sales  charge  (CDSC)  imposed  on
redemptions  made within the first 12 months after purchase.  Class Y shares are
sold without any sales  charge.  The rates of return will vary and the principal
value of an  investment  will  fluctuate  with  market  conditions.  Shares,  if
redeemed,  may be worth more or less than their original cost. A portion of each
class's  income  may  be  subject  to  federal  and  state  income  taxes.  Past
performance is not predictive of future investment results.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Trustees and Shareholders of
Tax-Free Fund of Colorado:

      We have  audited the  accompanying  statement  of assets and  liabilities,
including  the  schedule  of  investments,  of  Tax-Free  Fund of Colorado as of
December 31, 2005 and the related statement of operations,  statement of changes
in net assets,  and the  financial  highlights  for the year then  ended.  These
financial  statements  and financial  highlights are the  responsibility  of the
Fund's  management.  Our  responsibility  is to  express  an  opinion  on  these
financial  statements and financial highlights based on our audit. The statement
of changes in net assets for the year ended  December 31, 2004 and the financial
highlights for each of the years in the four year period ended December 31, 2004
have been  audited by other  auditors,  whose  report  dated  February  18, 2005
expressed an  unqualified  opinion on such  financial  statement  and  financial
highlights.

      We  conducted  our audit in  accordance  with the  standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain  reasonable  assurance about whether the
financial statements and financial highlights are free of material misstatement.
We were not  engaged to perform an audit of the  Fund's  internal  control  over
financial reporting.  Our audit included  consideration of internal control over
financial  reporting  as  a  basis  for  designing  audit  procedures  that  are
appropriate  in the  circumstances,  but not for the  purpose of  expressing  an
opinion on the  effectiveness  of the Fund's  internal  control  over  financial
reporting.  Accordingly,  we express  no such  opinion.  An audit also  includes
examining,  on a test basis,  evidence supporting the amounts and disclosures in
the financial  statements.  Our procedures  included  confirmation of securities
owned as of December 31, 2005, by correspondence with the custodian and brokers.
An audit also includes assessing the accounting  principles used and significant
estimates  made by  management,  as well as  evaluating  the  overall  financial
statement  presentation.  We believe that our audit provides a reasonable  basis
for our opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Tax-Free  Fund  of  Colorado  as of  December  31,  2005,  the  results  of  its
operations,  the changes in its net assets and the financial  highlights for the
year then ended, in conformity with accounting  principles generally accepted in
the United States of America.

                            TAX-FREE FUND OF COLORADO
                          NOTES TO FINANCIAL STATEMENTS
                                DECEMBER 31, 2005

1. ORGANIZATION

      Tax-Free  Fund of  Colorado  (the  "Fund"),  a  non-diversified,  open-end
investment company, was organized in February,  1987 as a Massachusetts business
trust and commenced  operations on May 21, 1987. The Fund is authorized to issue
an  unlimited  number of shares  and,  since its  inception  to April 30,  1996,
offered  only one class of shares.  On that date,  the Fund began  offering  two
additional classes of shares, Class C and Class Y shares. All shares outstanding
prior  to that  date  were  designated  as Class A  shares  and are sold  with a
front-payment  sales charge and bear an annual  distribution fee. Class C shares
are sold with a  level-payment  sales charge with no payment at time of purchase
but level service and  distribution  fees from date of purchase through a period
of six years thereafter. A contingent deferred sales charge of 1% is assessed to
any Class C  shareholder  who redeems  shares of this Class within one year from
the date of purchase.  Class C Shares,  together with a pro-rata  portion of all
Class  C  Shares   acquired   through   reinvestment   of  dividends  and  other
distributions paid in additional Class C Shares,  automatically convert to Class
A Shares  after 6 years.  The Class Y shares are only  offered  to  institutions
acting for an investor in a fiduciary,  advisory,  agency,  custodian or similar
capacity and are not offered  directly to retail  investors.  Class Y shares are
sold at net asset value without any sales charge,  redemption  fees,  contingent
deferred  sales charge or  distribution  or service fees. On April 30, 1998, the
Fund  established  Class I shares,  which  are  offered  and sold  only  through
financial intermediaries and are not offered directly to retail investors. Class
I Shares are sold at net asset value without any sales charge,  redemption fees,
or contingent  deferred sales charge.  Class I Shares carry a  distribution  and
service  fee.  As of the report  date no Class I Shares  were  outstanding.  All
classes of shares  represent  interests in the same portfolio of investments and
are identical as to rights and  privileges but differ with respect to the effect
of sales  charges,  the  distribution  and/or  service fees borne by each class,
expenses  specific to each class,  voting  rights on matters  affecting a single
class and the exchange privileges of each class.

2. SIGNIFICANT ACCOUNTING POLICIES

      The following is a summary of significant  accounting policies followed by
the Fund in the  preparation  of its financial  statements.  The policies are in
conformity with accounting principles generally accepted in the United States of
America for investment companies.

a)    PORTFOLIO VALUATION:  Municipal securities which have remaining maturities
      of more than 60 days are valued at fair value each business day based upon
      information provided by a nationally prominent independent pricing service
      and periodically  verified through other pricing services.  In the case of
      securities for which market quotations are readily  available,  securities
      are valued by the pricing service at the mean of bid and asked quotations.
      If market  quotations  or a  valuation  from the  pricing  service  is not
      readily available, the security is valued at fair value determined in good
      faith under procedures established by and under the general supervision of
      the Board of



      Trustees.  Securities  which  mature  in 60  days or less  are  valued  at
      amortized  cost if their term to  maturity at purchase is 60 days or less,
      or by amortizing their unrealized appreciation or depreciation on the 61st
      day prior to  maturity,  if their term to maturity at purchase  exceeds 60
      days.

b)    SECURITIES   TRANSACTIONS  AND  RELATED  INVESTMENT   INCOME:   Securities
      transactions  are  recorded on the trade date.  Realized  gains and losses
      from  securities  transactions  are reported on the identified cost basis.
      Interest income is recorded daily on the accrual basis and is adjusted for
      amortization  of  premium  and  accretion  of  original  issue and  market
      discount.

c)    FEDERAL  INCOME  TAXES:  It is the  policy  of the  Fund to  qualify  as a
      regulated  investment  company by  complying  with the  provisions  of the
      Internal Revenue Code applicable to certain investment companies. The Fund
      intends to make  distributions of income and securities profits sufficient
      to relieve it from all, or  substantially  all,  Federal income and excise
      taxes.

d)    MULTIPLE   CLASS   ALLOCATIONS:   All   income,   expenses   (other   than
      class-specific  expenses), and realized and unrealized gains or losses are
      allocated  daily to each class of shares  based on the relative net assets
      of each class.  Class-specific  expenses,  which include  distribution and
      service  fees and any other items that are  specifically  attributed  to a
      particular class, are charged directly to such class.

e)    USE OF ESTIMATES:  The  preparation of financial  statements in conformity
      with  accounting  principles  generally  accepted in the United  States of
      America requires  management to make estimates and assumptions that affect
      the  reported   amounts  of  assets  and  liabilities  and  disclosure  of
      contingent assets and liabilities at the date of the financial  statements
      and the  reported  amounts of increases  and  decreases in net assets from
      operations during the reporting  period.  Actual results could differ from
      those estimates.

f)    RECLASSIFICATION  OF CAPITAL  ACCOUNTS:  Accounting  principles  generally
      accepted in the United States of America  require that certain  components
      of net assets relating to permanent  differences be  reclassified  between
      financial and tax reporting. These reclassifications have no effect on net
      assets or net  asset  value  per  share.  On  December  31,  2005 the Fund
      increased  undistributed  net  investment  income by  $658,171,  increased
      accumulated net realized gain on investments by $146 and decreased capital
      stock by  $658,317  due  primarily  to  differing  book/tax  treatment  of
      distributions and bond amortization.

3. FEES AND RELATED PARTY TRANSACTIONS

investment  program of the Fund and the  composition of its portfolio,  arranges
for the  purchases  and sales of  portfolio  securities,  and provides for daily
pricing of the Fund's portfolio.  For its services,  the Sub-Adviser is entitled
to receive a fee from the Manager  which is payable  monthly and  computed as of
the close of  business  each day at the annual  rate of 0.20 of 1% on the Fund's
average net assets.

      Under a Compliance  Agreement with the Manager, the Manager is compensated
for Chief  Compliance  Officer related  services  provided to enable the Fund to
comply with Rule 38a-1 of the Investment Company Act of 1940.

      Specific  details  as to the  effect  of the  Fund's  payments  under  its
Distribution  Plan, as described  below, on the above  management fees and as to
the  nature  and  extent  of the  services  provided  by  the  Manager  and  the
Sub-Adviser  are more fully  defined in the Fund's  Prospectus  and Statement of
Additional Information.

b) DISTRIBUTION AND SERVICE FEES:

      The Fund has adopted a  Distribution  Plan (the  "Plan")  pursuant to Rule
12b-1 (the "Rule") under the Investment  Company Act of 1940.  Under one part of
the Plan, with respect to Class A Shares, the Fund is authorized to make service
fee payments to broker-dealers or others  ("Qualified  Recipients")  selected by
Aquila Distributors,  Inc. (the "Distributor"),  including,  but not limited to,
any principal  underwriter of the Fund,  with which the  Distributor has entered
into  written  agreements  contemplated  by the Rule  and  which  have  rendered
assistance  in the  distribution  and/or  retention  of  the  Fund's  shares  or
servicing of  shareholder  accounts.  The Fund  currently  makes payment of this
distribution  fee at the  annual  rate of 0.05 of 1% of the Fund's  average  net
assets  represented  by Class A Shares.  The Board of Trustees and  shareholders
approved an  amendment to the Fund's  Distribution  Plan  applicable  to Class A
Shares which permits the Fund to make service fee payments at the rate



of up to 0.15 of 1% on the entire net assets  represented by Class A Shares. For
the year ended December 31, 2005,  distribution  fees on Class A Shares amounted
to $111,347 of which the Distributor retained $3,626.

      Under  another part of the Plan,  the Fund is  authorized to make payments
with  respect to Class C Shares to  Qualified  Recipients  which  have  rendered
assistance in the distribution  and/or retention of the Fund's Class C shares or
servicing of shareholder accounts. These payments are made at the annual rate of
0.75% of the Fund's average net assets represented by Class C Shares and for the
year ended  December  31,  2005,  amounted to  $106,790.  In  addition,  under a
Shareholder  Services  Plan, the Fund is authorized to make service fee payments
with respect to Class C Shares to Qualified  Recipients  for providing  personal
services and/or maintenance of shareholder accounts.  These payments are made at
the annual rate of 0.25 of 1% of the Fund's  average net assets  represented  by
Class C Shares and for the year ended December 31, 2005 amounted to $35,597. The
total of these  payments with respect to Class C Shares  amounted to $142,387 of
which the Distributor retained $29,550.

      Specific  details  about the Plans are more  fully  defined  in the Fund's
Prospectus and Statement of Additional Information.

      Under a Distribution  Agreement,  the Distributor  serves as the exclusive
distributor of the Fund's shares. Through agreements between the Distributor and
various  broker-dealer  firms ("dealers"),  the Fund's shares are sold primarily
through the facilities of these dealers having offices within Colorado, with the
bulk of sales commissions  inuring to such dealers.  For the year ended December
31, 2005,  total  commissions on sales of Class AShares  amounted to $380,724 of
which the Distributor received $70,562.

c) OTHER RELATED PARTY TRANSACTIONS:

      For the year ended December 31, 2005, the Fund incurred  $100,252 of legal
fees  allocable to Hollyer Brady Barrett & Hines LLP,  counsel to the Fund,  for
legal services in conjunction with the Fund's ongoing operations.  The Secretary
of the Fund is a Partner in that firm.

4. PURCHASES AND SALES OF SECURITIES

      During the year ended  December 31,  2005,  purchases  of  securities  and
proceeds from the sales of securities  aggregated  $26,540,980 and  $31,231,240,
respectively.

      At December  31,  2005,  the  aggregate  tax cost for all  securities  was
$235,546,347.  At December 31, 2005 the aggregate gross unrealized  appreciation
for all  securities  in which  there is an excess of market  value over tax cost
amounted to  $8,748,439  and aggregate  gross  unrealized  depreciation  for all
securities in which there is an excess of tax cost over market value amounted to
$218,337 for a net unrealized appreciation of $8,530,102.



5. PORTFOLIO ORIENTATION

      Since the Fund  invests  principally  and may  invest  entirely  in double
tax-free  municipal  obligations  of issuers within  Colorado,  it is subject to
possible risks  associated with economic,  political,  or legal  developments or
industrial  or regional  matters  specifically  affecting  Colorado and whatever
effects these may have upon Colorado issuers' ability to meet their obligations.

6. EXPENSES

      The Fund has negotiated an expense offset  arrangement  with its custodian
wherein it receives credit toward the reduction of custodian fees and other Fund
expenses  whenever  there  are  uninvested  cash  balances.   The  Statement  of
Operations  reflects the total expenses before any offset,  the amount of offset
and the net expenses.  It is the general intention of the Fund to invest, to the
extent  practicable,  some or all of cash  balances in  income-producing  assets
rather than leave cash on deposit.

7. CAPITAL SHARE TRANSACTIONS

      Transactions in Capital Shares of the Fund were as follows:

8. TRUSTEES' FEES AND EXPENSES

      At December  31, 2005 there were 7  Trustees,  one of which is  affiliated
with the Manager and is not paid any fees. The total amount of Trustees' service
and  attendance  fees paid during the year ended December 31, 2005 was $104,075,
to cover  carrying  out  their  responsibilities  and  attendance  at  regularly
scheduled quarterly Board Meetings and meetings of the Independent Trustees held
prior to each quarterly Board Meeting.  When additional or special  meetings are
held, the meeting fees are paid to those  Trustees in  attendance.  Trustees are
reimbursed for their expenses such as travel,  accommodations and meals incurred
in  connection  with  attendance  at Board  Meetings  and the Annual  Meeting of
Shareholders.  For the  year  ended  December  31,  2005,  such  meeting-related
expenses amounted to $32,069.

9. SECURITIES TRADED ON A WHEN-ISSUED BASIS

      The  Fund  may  purchase  or  sell  securities  on  a  when-issued  basis.
When-issued transactions arise when securities are purchased or sold by the Fund
with payment and delivery  taking place in the future in order to secure what is
considered  to be an  advantageous  price  and  yield to the Fund at the time of
entering  into the  transaction.  Beginning  on the date the Fund  enters into a
when-issued  transaction,  cash or other liquid  securities are segregated in an
amount equal to or greater than the amount of the when-issued transaction. These
transactions  are  subject to market  fluctuations  and their  current  value is
determined in the same manner as for other securities.

10. INCOME TAX INFORMATION AND DISTRIBUTIONS

      The Fund declares  dividends  daily from net  investment  income and makes
payments monthly in additional shares at the net asset value per share, in cash,
or in a combination of both, at the shareholder's  option.  Net realized capital
gains, if any, are distributed annually and are taxable.

      The  Fund  intends  to  maintain,  to the  maximum  extent  possible,  the
tax-exempt  status  of  interest  payments  received  from  portfolio  municipal
securities in order to allow dividends paid to shareholders  from net investment
income to be exempt from  regular  Federal and State of Colorado  income  taxes.
However,  due  to  the  distribution  levels  maintained  by the  Fund  and  the
differences  between  financial  statement  reporting  and  Federal  income  tax
reporting  requirements,  distributions  made by the Fund may not be the same as
the Fund's net  investment  income,  and/or net realized  securities  gains.  At
December 31,  2005,  the Fund had a capital  loss  carryover  of $245,339  which
expires on December 31, 2012.  This  carryover is available to offset future net
realized  gains on  securities  transactions  to the extent  provided for in the
Internal  Revenue Code. To the extent that this loss carryover is used to offset
future  realized  capital gains,  it is probable the gains so offset will not be
distributed.



      The tax character of distributions:

                                                Year Ended December 31,
                                                 2005              2004
                                             -----------       -----------
      Net tax-exempt income                  $ 9,394,426       $ 9,625,055
      Ordinary income                            546,600           682,897
                                             -----------       -----------

                                             ===========       ===========

      As of December 31, 2005, the components of distributable earnings on a tax
basis were as follows:

      Unrealized appreciation                                 $ 8,530,102
      Accumulated net realized loss                              (245,339)
                                                              -----------
                                                              $ 8,284,763
                                                              ===========

      The difference between book basis and tax basis unrealized appreciation is
attributable primarily to premium/discount adjustments.

11. CHANGE IN PRINCIPAL ACCOUNTANTS

      KPMG LLP was previously the principal accountants for the Tax-Free Fund of
Colorado  (the  "Fund").  On July 27, 2005 KPMG LLP  resigned  as the  principal
accountants  of the Fund and  Tait,  Weller  and Baker  LLP was  engaged  as the
principal  accountants to audit the Fund's  financial  statements for the fiscal
year of 2005.  The  decision  was made by the  Audit  Committee  of the Board of
Trustees.

      The audit reports of KPMG LLP on the Fund's financial statements as of and
for the years  ended  December  31,  2004 and 2003 did not  contain  an  adverse
opinion or  disclaimer  of opinion,  nor were they  qualified  or modified as to
uncertainty, audit scope, or accounting principles.

      In connection  with the audits of the two fiscal years ended  December 31,
2004 and 2003 and the subsequent  interim  period  through July 27, 2005,  there
were no  reportable  events  or  disagreements  with  KPMG LLP on any  matter of
accounting principles of practices,  financial statement disclosure, or auditing
scope or procedures,  which disagreements if not resolved to the satisfaction of
KPMG LLP would have  caused  them to make  reference  in  connection  with their
opinion to the subject matter of the disagreements.

ANALYSIS OF EXPENSES (UNAUDITED)

      As a  shareholder  of the Fund,  you may  incur  two  types of costs:  (1)
transaction  costs,  including  front-end  sales charges with respect to Class A
shares or contingent  deferred  sales  charges  ("CDSC") with respect to Class C
shares; and (2) ongoing costs,  including  management fees;  distribution and/or
service (12b-1) fees; and other Fund expenses.  The tables below are intended to
help you understand your ongoing costs (in dollars) of investing in the Fund and
to compare  these  costs with the ongoing  costs of  investing  in other  mutual
funds.

      The tables below are based on an investment of $1,000  invested on July 1,
2005 and held for the six months ended December 31, 2005.

ACTUAL EXPENSES

      This table  provides  information  about actual  account values and actual
expenses.  You may use the information provided in this table, together with the
amount you invested,  to estimate the expenses that you paid over the period. To
estimate the expenses you paid on your account, divide your ending account value
by $1,000 (for example, an $8,600 ending account value divided by $1,000 = 8.6),
then multiply the result by the number under the heading entitled "Expenses Paid
During the Period".

      ANY,  AT NET  ASSET  VALUE  AND  DOES NOT  REFLECT  THE  DEDUCTION  OF THE
      APPLICABLE  SALES CHARGES WITH RESPECT TO CLASS A SHARES OR THE APPLICABLE
      CONTINGENT DEFERRED SALES CHARGES ("CDSC") WITH RESPECT TO CLASS C SHARES.
      TOTAL RETURN IS NOT  ANNUALIZED,  AS IT MAY NOT BE  REPRESENTATIVE  OF THE
      TOTAL RETURN FOR THE YEAR.

(2)   EXPENSES ARE EQUAL TO THE  ANNUALIZED  EXPENSE  RATIO OF 0.80%,  1.75% AND
      0.75% FOR THE FUND'S CLASS A, C AND Y SHARES, RESPECTIVELY,  MULTIPLIED BY
      THE  AVERAGE  ACCOUNT  VALUE OVER THE  PERIOD,  MULTIPLIED  BY 184/365 (TO
      REFLECT THE ONE-HALF YEAR PERIOD).

ANALYSIS OF EXPENSES (UNAUDITED) (CONTINUED)

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

      The table below provides information about hypothetical account values and
hypothetical  expenses  based on the actual expense ratio and an assumed rate of
return of 5.00% per year before expenses, which is not the Fund's actual return.
The  hypothetical  account  values and  expenses may not be used to estimate the
actual ending account  balance or expenses you paid for the period.  You may use
the information provided in this table to compare the ongoing costs of investing
in the Fund and other mutual funds.  To do so,  compare this 5.00%  hypothetical
example relating to the Fund with the 5.00% hypothetical examples that appear in
the shareholder reports of other mutual funds.

      Please  note  that the  expenses  shown in the  table  below  are meant to
highlight  your ongoing costs only and do not reflect any  transactional  costs,
with respect to Class A shares.  The example  does not reflect the  deduction of
contingent  deferred  sales  charges  ("CDSC")  with  respect to Class C shares.
Therefore,  the table is useful in comparing  ongoing  costs only,  and will not
help you determine the relative total costs of owning different mutual funds. In
addition,  if these transaction costs were included,  your costs would have been
higher.

ITEM 2. CODE OF ETHICS.

(a) As of December 31, 2005 (the end of the reporting period) the
Trust has adopted a code of ethics that applies to the Fund's
principal executive officer(s)and principal financial officer(s)
and persons performing similar functions ("Covered Officers") as
defined in the Aquila Group of Funds Code of Ethics for Principal
Executive and Senior Financial Officers under Section 406 of the
Sarbanes-Oxley Act of 2002.;

(f)(1) Pursuant to Item 10(a)(1), a copy of the Fund's Code of
 Ethics that applies to the Trust's principal executive officer(s)
 and principal financial officer(s) and persons performing similar
functions is included as an exhibit to its annual report on this
Form N-CSR;

(f)(2)  The text of the Fund's Code of Ethics that applies to the
Fund's principal executive officer(s) and principal financial
officer(s) and persons performing similar functions has been
posted on its Internet website which can be found at the Fund's
Internet address at aquilafunds.com.


ITEM 3.  AUDIT COMMITTEE FINANCIAL EXPERT.

(a)(1)(ii) The Board of Trustees of the Fund has determined that
it does not have at least one audit committee financial expert
serving on its audit committee.  The Fund does not have such a
person serving on the audit committee because none of the persons
currently serving as Trustees happens to have the technical
accounting and auditing expertise included in the definition of
"audit committee financial expert" recently adopted by the Securities
and Exchange Commission in connection with this Form N-CSR, and the
Board has not heretofore deemed it necessary to seek such a person
for election to the Board.

The primary mission of the Board, which is that of oversight over
the operations and affairs of the Fund, confronts the Trustees with
a wide and expanding range of issues and responsibilities. The
Trustees believe that, accordingly, it is essential that the Board's
membership consist of persons with as extensive experience as possible
in fulfilling the duties and responsibilities of mutual fund directors
and audit committee members and, ideally, with extensive experience
and background relating to the economic and financial sectors and
securities in which the Fund invests, including exposure to the
financial and accounting matters commonly encountered with respect
to those sectors and securities.  The Board believes that its current
membership satisfies those criteria.  It recognizes that it would
also be helpful to have a member with the relatively focused accounting
and auditing expertise reflected in the applicable definition of
"audit committee financial expert," just as additional members with
similarly focused technical expertise in other areas relevant to
the Fund's operations and affairs would also contribute added value.
However, the Board believes that the Fund is better served, and its
assets better employed, by a policy of hiring experts in various
the specialized area of technical accounting and
auditing matters, if and as the Board identifies the need, rather
than by seeking to expand its numbers by adding technical experts
in the areas constituting its domain of responsibility.  The Fund's
Audit Committee Charter explicitly authorizes the Committee to
retain such experts as it deems necessary in fulfilling its duties
under the Charter.
