DEAR SHAREHOLDER:

     The Parnassus Funds will hold a shareholders meeting on Tuesday, October 5,
2004 at 6:00 p.m. at the Sheraton-Palace Hotel in San Francisco.  The purpose of
the meeting will be to elect four  Trustees to the Funds' board and to vote on a
proposal to reduce the mandatory  retirement age of independent Trustees from 75
to 70. The idea behind  lowering the retirement age is to prevent the board from
getting  too old.  The  current  Trustees  are all  around 60 years  old,  so it
wouldn't  affect  the  current  board for about ten  years.  This  means that no
current board member will take it personally.  Although some people are vigorous
well into their 70s, not everyone is. If approved, this proposal should minimize
the chance that someone will have to undertake the  unpleasant job of suggesting
that a Trustee resign because of underperformance due to age.

     Four candidates have been nominated for the Trustee  positions:  Herbert A.
Houston,  Jeanie S. Joe, Jerome L. Dodson and Donald V. Potter. Herb Houston has
served as a Trustee for the Parnassus Income Trust since 1992 and since 1998 for
the Parnassus Fund. He is a graduate of California  State  University at Hayward
and holds master's degrees in public health and public  administration  from the
University of Southern California. From 1987 through 1998, Mr. Houston was chief
executive officer of the Haight Ashbury Free Clinics.  Since 1998, he has been a
healthcare consultant and has owned and operated several small businesses.

     Donald  Potter  is a  graduate  of Notre  Dame  University  and of  Harvard
Business  School.  His  professional  career has been in management  consulting,
having  been  a  partner  with  McKinsey  &  Co.  and  President  of  Windermere
Associates.  He  is  the  principal  of  StrategyStreet,   a  business  strategy
consulting  firm.  He has  served as a  Trustee  of the  Parnassus  Fund and the
Parnassus Income Trust since 2002.

     Jeanie Joe  graduated in dietetics  from the  University  of  California at
Berkeley and received a master's in public health from UCLA. She has worked as a
clinical  dietician.   Since  1995,  she  has  been  President  of  Geo/Resource
Consultants, a geotechnical and environmental consulting firm.

     There will be a  reception  at 6:00 pm on October 5 and the formal  meeting
will begin at 7:00 p.m. After the meeting,  Todd Ahlsten,  portfolio  manager of
the Parnassus  Equity Income Fund,  and I will answer  questions  until 8:30. If
you're in the San Francisco Bay Area, we hope you will join us.

     You  should  have  already  received  a formal  mailing  including  a proxy
statement.  This contains more  information  about the meeting,  but I wanted to
remind you so you can mark your calendar. Your vote is important, so please mark
your proxy ballot and send it back right away. You can also vote by telephone or
on the Internet. I hope you will vote for me and the other three candidates, and
I hope you will vote to lower the  retirement  age.  Also, if you plan to attend
the reception, please RSVP by marking the proxy ballot, so we will know how many
people to expect. I hope to see you on October 5.

PERSONNEL MATTERS

     Two new people have  recently  joined our staff.  Jack Gee has joined us as
our new chief financial officer. Jack is a certified public accountant (CPA) and
holds a bachelor's  degree in accounting  from  California  State  University at
Hayward.  He has  served as chief  financial  officer at two other  mutual  fund
groups: SIFE Trust Fund and Fremont Investment Advisors.

     Marc Mahon joins as Manager - Fund  Administration.  He holds a  bachelor's
degree in finance  from  Arizona  State  University  and is an MBA  candidate at
California State University in Hayward. Previously, he worked at Barclays Global
Investors and for Fremont Investment Advisors.

     Below you will find  semiannual  reports on each of the three  funds in the
Parnassus Income Trust. Todd Ahlsten wrote the reports on the Equity Income Fund
and the Fixed-Income  Fund, while  co-managers Ben Liao and Stephen Dodson wrote
the California Tax-Exempt Fund report.

                                        Yours truly,

                                        /s/ Jerome L. Dodson

                               EQUITY INCOME FUND

     As of June 30,  2004,  the net asset  value per share  (NAV) of the  Equity
Income Fund was $24.38, so after taking dividends into account, the total return
for the first six months of the year was 2.84%. This compares to a gain of 3.44%
for the S&P 500 and a gain of 3.15% for the average  equity income fund followed
by Lipper.  While the Fund underperformed its last year because of our defensive
strategy,  its long-term  returns remain  excellent.  The Fund's three, five and
ten-year  returns beat the Lipper  average and S&P 500 for every period.  We are
pleased to report that our  five-year  return of 8.13%,  which  encompasses  the
three-year bear market and two bull-market  years,  beat the S&P 500's return by
over 10% annually.

     Below is a table that compares the performance of the Fund with the S&P 500
and the average  equity  income fund  followed by Lipper.  Average  annual total
returns are for the one, three, five and ten-year periods.

     performance  data quoted,  and current  performance  information  is on the
     Parnassus website (www.parnassus.com). Before investing, an investor should
     consider  the  investment  objectives,  risks,  charges and expenses of the
     Equity  Income  Fund and should read the  prospectus  which  contains  this
     information.  The prospectus is on the Parnassus website or you can get one
     by calling  (800)  999-3505.  Investment  return and  principal  value will
     fluctuate,  so that an investor's shares, when redeemed,  may be worth more
     or less than their  original  cost.  The S&P 500 is an  unmanaged  index of
     common stocks, and it is not possible to invest directly in an index. Index
     figures do not take any expenses into account,  but mutual fund returns do.
     Returns  shown  in the  table  do not  reflect  the  deduction  of  taxes a
     shareholder  would pay on fund  distributions  or redemption of shares.  On
     March 31, 1998 the Fund changed its  investment  objective  from a balanced
     portfolio to and equity-income portfolio.

MARKET RECAP

     Our  return of 2.84%  was  essentially  in line with the S&P 500's  gain of
3.15% for the first  half of 2004.  However,  during the first six months of the
year,  the stock  market was like a bumpy  airline  flight.  Soaring oil prices,
violence in Iraq and uneven  economic data  provided a stiff  headwind for stock
prices.  However,  strong corporate profits and significant  pockets of economic
strength provided the lift required to push stocks higher by midyear.

     The  year  started  strong  as the S&P 500 was up 3% by  January  27 due to
strong   corporate   profits  and   optimism   about  the   economic   recovery.
Unfortunately,  this  excitement  faded fast and the S&P 500  plunged  5.6% from
March 5 to March 24 due to investor concerns over higher interest rates, renewed
inflation  and soaring oil prices.  We used this March  decline to become  fully
invested after our defensive positioning of 2003.

     Being fully  invested,  we were  pleased  when the S&P 500 jumped 5.2% from
March 25 to April 6 as oil prices fell,  and investors  looked forward to strong
first quarter earnings. However, because of high oil prices and

                                       3


weak economic data, this rally was also short-lived and the S&P 500 slid 5.3% to
a new yearly low of 1076 by May 12. Fortunately,  oil prices fell in June, and a
renewed  outlook for strong  corporate  profits ignited a rally which pushed our
Fund's return to a positive 2.84% for the first half.

STRATEGY

     While the market has been  choppy  this year,  we remain  focused on owning
good  companies  for the long term.  We look to buy stocks  with  price-earnings
(P/E)  multiples  below 20, that have earnings  growth of at least 10%, and have
returns  on  equity  of at  least  15%.  As of this  writing,  the Fund is fully
invested with less than 3% cash. While the economic  recovery has been uneven, I
feel  stock  prices  can rise  during  the  second  half of 2004 based on strong
corporate  profits and good  economic  data.  While  interest  rates will likely
increase  during the second  half of 2004,  they are still very low in  absolute
terms,  and this should keep the economy  growing.  Inflation  also  remains low
which is a positive for the economy and stock prices.  The S&P 500, valued at 21
times trailing earnings,  is not a bargain,  but we have found good companies to
own that trade for 15-18 times earnings with solid growth prospects.

     To give you an example of the investment  opportunities  we are finding,  I
want to talk about one of our largest holdings, Gannett Corporation.  Gannett is
an international  publisher that owns 101 daily newspapers  including USA TODAY,
the  nation's   largest-selling  daily  newspaper.  The  company  also  owns  22
television  stations in major U.S.  markets.  Starting  with the  valuation  and
financials,  Gannett  fits our  profile as the  company  trades at only 16 times
estimated 2004  earnings,  which is at the low end of its five-year P/E range of
14-27. In addition,  Gannett has a five-year average return on equity of 21% and
is run by a well regarded CEO named Douglas McCorkindale. Few executives can say
they've worked for a company like Gannett that has increased  earnings per share
in 32 of the past 35 years.

     While the financial ratios are attractive, the most interesting part of the
Gannett story is that there are several  important  catalysts  that may move the
stock higher. First and foremost, advertising budgets are finally rebounding due
to the improving economy. Second, Gannett's sales will jump from major political
advertising during the second half of this year.  Finally,  profits at Gannett's
13 NBC-affiliates will rise during the third quarter as they air the 2004 Summer
Olympics.

     While 2004 will be strong,  2005 should be another  record year for Gannett
as the company will  increase the price for USA TODAY from 50(cent) to 75(cent),
which  should add about $40  million to net  income.  Gannett  owns great  media
properties, and with over $1.2 billion a year of free cash flow, the company has
significant resources to either buy back stock or acquire other media companies.
Management does a great job controlling costs, so revenue growth translates into
good profit growth.

     Gannett is also a good corporate citizen.  The company's Gannett Foundation
has donated $96.5 million from 1991-2003 to charitable organizations. Gannett is
also known for strong corporate  governance and diversity as the company has had
many prominent women on its board,  including former first lady Roslyn Carter. I
had a chance  to  speak  with  CFO  Gracia  Martore  during  March  and was very
impressed with her management  skills.  Gannett also has a remarkable record for
diversity at the operating level. Each year, an executive's  performance  review
is partially based on success in achieving diversity.

     I think  Gannett's  stock  can rise 32% over the next year from $81 to $107
and boost the return of the  Parnassus  Equity Income Fund. My estimate is based
on 20 times projected 2005 earnings of $5.35 per share. If the economy  softens,
I feel our downside risk is only 10%.

                                       4


     As  of  this  writing,  major  industry  weightings  of  the  Fund  include
healthcare,  financial services,  insurance and publishing. These are industries
where we have found  undervalued  businesses  that can  benefit  from  improving
economic   conditions.   We  have  significantly   reduced  our  investments  in
natural-gas  utilities as those stocks  typically fall when interest rates rise.
We continue to own a few utility  companies,  because  they either  benefit from
higher natural-gas prices or offer above-average growth potential. The SEC yield
for June was 1.64%.

LOSERS

     The Fund had three  stocks which hurt the NAV by 4(cent) or more during the
first  half of 2004.  The  biggest  loser was  First  Health  Group,  which is a
full-service  health benefits provider.  First Health's stock plunged 19.8% from
$19.46 to $15.61,  which hurt the Fund's NAV by 9(cent).  The company's earnings
fell below plan as its network  added fewer members than expected and was hit by
intense  price  competition.  We are  holding  onto our  shares as the stock now
trades for only 10 times earnings, and we feel First Health's preferred provider
network has significant value.

     Hospital operator Health Management  Associates (HMA) fell 9.2% from $24 to
$21.80,  our average  selling  price,  which cost the Fund 5(cent).  We sold our
shares because of concerns about increasing bad debt and lower patient admission
growth.

     TriQuint Semiconductor, a company that designs and makes computer chips for
cell phones and  communication  equipment  fell 33.9% from our  average  cost of
$8.31 to our selling price of $5.49,  which  reduced our NAV by 4(cent).  I made
the mistake of buying a mediocre  business that appeared set for recovery.  Once
it became  clear  TriQuint's  new product wins  weren't  equating  into a strong
profit ramp, I sold the stock.

WINNERS

     The Fund's  biggest winner was Electro  Scientific  Industries  (ESI),  the
Portland,  Oregon-based  maker of  semiconductor  capital  equipment.  The stock
jumped 24.6% from our average  cost of $22.60 to $28.31 which added  16(cent) to
the NAV. In June,  ESI  announced  that orders rose an amazing  310% versus last
year as the  company's  customers  began to add  capacity  after  three years of
depressed investment.

     Johnson & Johnson  added  8(cent) to the NAV as its stock  price  increased
7.8% to $55.70 from  $51.66.  The  company's  stock price was  depressed  at the
beginning  of the year due to  concerns  about  its weak drug  pipeline  and new
competition in the drug-eluting stent market.  Johnson & Johnson reported strong
first-half earnings and the stock bounced back.

     Pitney Bowes,  the leading maker of postage  meters and mailing  equipment,
increased  the NAV by 7(cent) as its stock  rose 9.2% from our  average  cost of
$40.94 to $44.25.  The stock  increased  as  investors  expected  the company to
report  stronger  earnings  because of higher sales of digital postal meters and
other benefits from a stronger economy.

     Genuine Parts  Corporation,  the owner of Napa Auto Parts, added 6(cent) to
the NAV as the stock rose 19.5% to $39.68 from $33.20.  The company had a strong
start to the year as sales increased 9% during the first quarter.

     Quest Diagnostics, the leading laboratory company, added 5(cent) to the NAV
as its stock  price  climbed  16.1% from our  average  cost of $73.34 to $84.95.
Earnings are strong based on new clinical  tests,  lower  bad-debt  expenses and
stable pricing.

                                       5


     Dental-distribution  company  Patterson  Dental also  increased  the NAV by
5(cent)  as its stock rose 21.1% from  $64.16 to our  average  selling  price of
$77.76. Patterson is a great company that is having another record year be-cause
of market share gains and acquisitions.  We did, however, sell the stock because
it reached our calculated intrinsic value.

COMPANY NOTES

     One of my favorite new investments in the Fund is called Trex Company,  the
largest  manufacturer of composite decking products,  or "imitation  lumber," as
our  President  Jerry Dodson likes to call it. Trex is a great example of "doing
well by doing good" as the company essentially makes its sturdy composite lumber
by blending  reclaimed  polyethylene  (plastic  grocery bags) with recycled wood
chips.  After hearing  about the company from an industry  contact at a Saturday
morning brunch, I called Trex's  headquarters to start the research  process.  I
was quite  pleased  when Trex's CFO Paul  Fletcher was willing to fly across the
country  from  Winchester,  Virginia  to meet me in a  little-known  town called
Fernley, Nevada to tour the company's west coast manufacturing operation.

     After a five hour drive,  which took me from beautiful San Francisco to the
tumbleweed  terrain of the Nevada  desert,  I met Mr.  Fletcher  in the lobby of
Trex's  250,000  square foot facility in Fernley.  After an hour  discussing the
company's financial statements and business plan over a cup of coffee,  Fletcher
handed me goggles and a pair of earplugs.  Along with the Fernley plant manager,
we entered the manufacturing  facility.  I was amazed to see these huge bails of
reclaimed  polyethylene  that  were  being  unbundled  and put  into a  grinding
operation.  Adjacent to the grinding  operation was a sister  process called the
"hammermill"  operation,  where chips of waste wood (from  crates,  for example)
were  ground  up like  flour.  These  two  ingredients,  along  with a few other
additives  for  color,  were then sent to one of eight  manufacturing  lines for
mixing where the materials were heated to  approximately  600 degrees and joined
together.  Once mixed,  the batch was extruded into boards and put on a conveyor
belt  where  they  were  left to cool for 12 hours.  We then  walked  over to an
embossing area where I watched a machine add grain to the boards to complete the
manufacturing process for Trex's new "Accents" line.

     The plant  employs  about 130 people,  and I was truly  impressed  with its
efficiency and technology.  After touring the main manufacturing  site, Fletcher
showed me an impressive  quality-control  room where Trex was testing boards for
strength,  texture  and  color.  Most  impressive  was a  special  machine  that
simulated  intense  sunlight  so they  could  determine  if the boards met their
"fade" criteria.

     In May, Trex made Business  Ethics "100 Best Corporate  Citizens" list, and
in June,  Trex was listed in Fortune's  Small Business  Magazine's  2004 List of
"100  Fastest  Growing  Small  Companies."  Trex should  boost the return of the
Parnassus  Equity  Income Fund as the company has the potential to grow at least
20% annually over the next several years as more decks are built with  composite
lumber.  If you are interested in seeing pictures of Trex's products,  check out
the company's website at www.trex.com.

     Thank you for investing in the Parnassus Equity Income Fund.

                                        Yours truly,

                                        /s/ Todd C. Ahlsten

                                FIXED-INCOME FUND

     As of  June  30,  2004,  the  net  asset  value  per  share  (NAV)  of  the
Fixed-Income Fund was $15.87, so after taking dividends into account,  the total
return for the first six months of the year was 0.16%.  This  compares to a loss
of 0.19% for the Lehman  Government/Corporate Bond Index and a loss of 0.18% for
the average A-Rated bond fund followed by Lipper.  The 30-day SEC yield for June
was 2.25%.  Below you will find a table that  compares  the  performance  of the
Fixed-Income  Fund with that of the Lehman  Government/Corporate  Bond Index and
the Lipper A-Rated Bond Fund Average.

     The Parnassus  Fixed-Income  Fund had a good first half in 2004, as we were
able to generate a slight gain of 0.16% versus a loss of 0.18% for our peers. As
we anticipated,  interest rates rose  dramatically  during the second quarter as
the ten-year Treasury bond yield increased from 4.25% to 4.58%.

     While we  underperformed  our  peers  over the past  year  because  of poor
performance  during  the  second  half of 2003,  our  long-term  returns  remain
excellent.  The Fund's three,  five and ten-year returns beat the Lipper A-Rated
Average for every period.

STRATEGY

     Our portfolio  remains  defensive as we expect higher interest rates during
the second half of 2004.  On June 30, the Federal  Reserve  announced  its first
rate hike in four  years as it  increased  the  federal  funds  rate by 0.25% to
1.25%.  With an improving  economy and four Federal  Reserve  meetings left this
year, I'm expecting at least three,  and potentially  four,  more  quarter-point
increases in the federal funds rate.  This would place that rate at  2.00%-2.25%
by year-end. Given this environment, our main strategy is to preserve capital by
keeping a short duration.  Duration essentially measures how much, in percentage
terms, a bond price will change for a 1% movement in yield.  As of this writing,
our duration is only 1.5 years.  This "short  duration"  strategy served us well
during  the second  quarter  as the Fund's  loss of 0.97% was much less than the
average Lipper A-Rated Fund, which fell 2.71%.

                                       7


     We  have  placed  11% of the  Fund in  convertible  bonds  and  convertible
preferred stock as those issues should rise in value with a stronger economy and
rising stock  prices.  In  addition,  these  investments  should help the Fund's
monthly dividend.  However, based on our portfolio strategy, the Fund's dividend
will remain low because short duration  bonds offer lower yields.  That said, as
we saw during the second  quarter,  this strategy  should  cushion our portfolio
should rates continue to increase.

     I anticipate we will  maintain our defensive  strategy for the next several
months as we wait for interest  rates to stabilize at a higher level.  Once that
happens,  we will extend the  portfolio's  duration which will position the Fund
for higher returns.

                                        Yours truly,

                           CALIFORNIA TAX-EXEMPT FUND

     As of June 30, 2004,  the net asset value per share (NAV) of the California
Tax-Exempt Fund was $16.80.  Taking dividends into account, the total return for
the  first  half  of  2004  was  a  negative  0.60%.   The  average   California
municipal-bond fund followed by Lipper, Inc. had a loss of 0.96%. This places us
#25 out of the 128 funds  followed  by Lipper  for  year-to-date  returns.*  The
results showed that our strategy of keeping the Fund defensively positioned paid
off in the rising interest-rate environment of the past two quarters.

     Below you will find a table that  compares  our  annual  returns to various
indices  over the past one,  three,  five and ten-year  periods.  The 30-day SEC
yield for June 2004 was 2.74%.

     * For the one,  three,  five,  and  ten-year  periods  ended  6/30/04,  the
     Parnassus  California  Tax-Exempt Fund placed #65 of 128 funds,  #33 of 110
     funds, #21 of 96 funds, and #17 of 57 funds, respectively.

     On June 30, the Federal Reserve raised the federal-funds rate for the first
time in four years,  increasing the benchmark rate by 0.25% to 1.25%. While this
decision was made at the end of the second  quarter,  the decision was very much
expected since early in the year. Historically,  the Fed had a policy of secrecy
about its monetary-policy decisions, and investors spent a lot of time trying to
figure  out what the Fed would do next.  Once the Fed  announced  its  decision,
markets would move decisively,  causing joy or grief, depending on the direction
and amount of the change in rates. The Fed has since adopted a policy of greater
communication with the public and investors, giving the market more insight into
how it arrives at its decision and what  investors  can  anticipate  in its next
decision.  In short,  the bond market has been moving  downward  (with  interest
rates moving upward) long before the Fed's decision became official.

     But what does this all mean for us?  Well,  it means  that the value of the
bonds in our portfolio  decreased over the first half of the year as the economy
recovered and interest rates increased. As most of you have been aware of, we've
been anticipating  this since last year and adjusted our portfolio  accordingly.
We did adjust our  portfolio  a little  too early,  and that  caused the Fund to
underperform late last year. However, our portfolio was in good shape when rates
finally rose this year. The Fund did lose 2.09% in the second quarter of 2004 as
bond prices  dropped,  but we still  managed to outperform  the Lipper  average,
which lost 2.46% during the same period (the Fund ranked #22 of 128 funds in the
second quarter).  While we don't want to cheer when the fund loses money, we did
outperform 80% of our peers in the first half of the year.

     California  state  bonds got a boost in May as Moody's  Investors  Services
raised the bond  rating  one notch to A3 from  Baa1.  An  improved  economy  and
optimism  about progress on a balanced  state budget  prompted the upgrade.  The
other two  rating  agencies,  Standard & Poor's  and Fitch  Ratings,  still have
ratings two notches below  Moody's  rating.  We anticipate  that they will boost
California's  credit rating once they see more evidence of an economic  recovery
and fiscal austerity.

OUTLOOK

     The Fed has said that they intend to increase  rates at a "measured"  pace.
The  economy is  certainly  recovering,  but the rate of the  recovery  is slow,
keeping  inflation in check.  This means that rates will  continue to rise,  but
probably  not  very  quickly.  To  continue  generating  good  returns  for  our
shareholders  in this market,  it comes down to a balancing act between  keeping
the Fund defensively  positioned as rates increase and generating  enough yield.
And unfortunately,  the two have a mathematically inverse relationship.  We will
continue  balancing  as we  monitor  economic  data  and  make  the  appropriate
adjustments to the portfolio as necessary.

     And as always, thank you for investing in the Fund.

                    Yours truly,

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1.   Significant Accounting Policies

     The Parnassus  Income Trust (the  "Trust"),  formerly The Parnassus  Income
     Fund,  organized on August 8, 1990 as a  Massachusetts  Business  Trust, is
     registered  under  the  Investment  Company  Act of 1940 as a  diversified,
     open-end  investment  management company comprised of three separate funds,
     each  offering  separate  shares.  The Equity  Income  Fund,  formerly  the
     Balanced Portfolio,  changed its primary investment  objective from current
     income and capital preservation to current income and capital appreciation;
     this change was effective on March 31, 1998. The Trust began  operations on
     August 31,  1992.  The  following  is a summary of  significant  accounting
     policies of the Trust.

     SECURITIES VALUATIONS:  Short-term securities are money-market  instruments
     and are valued at  amortized  cost,  which  approximates  market  value.  A
     market-value  adjustment  is applied to certain  short-term  securities  to
     reflect  penalties for early withdrawal and early call.  Equity  securities
     that are listed or traded on a national  securities  exchange are stated at
     market  value based on  recorded  closing  sales on the  exchange or on the
     Nasdaq's National Market System official closing price. In the absence of a
     recorded sale, and for over-the-counter  securities,  equity securities are
     stated  at the  mean  between  the  last  recorded  bid and  asked  prices.
     Long-term  fixed  income  securities  are valued  each  business  day using
     independent  pricing  services   ("Services")  approved  by  the  Board  of
     Trustees.  For fixed-income  securities with an active market,  the pricing
     services  value  them at the "bid"  price  where such  quotes  are  readily
     available  from  brokers and dealers and are  representative  of the actual
     market for such securities.  Other fixed-income  securities  experiencing a
     less  active  market  are valued as  determined  by the  Services  based on
     methods which include  consideration of trading in securities of comparable
     yield,  quality,  coupon,  maturity and type, as well as  indications as to
     values from dealers and other market data without  exclusive  reliance upon
     quoted  prices  or  over-the-counter  prices,  since  such  valuations  are
     believed to reflect more accurately the value of such securities.

     Equity and fixed-income  securities  without an active market are priced at
     their  fair  value,  in  accordance  with  procedures  established  by  the
     Trustees. In determining fair value, the trustees may consider a variety of
     information including but not limited to the following:  price based upon a
     multiple  of  earnings  or sales,  a discount  from the  market  value of a
     similar security,  fundamental analytical data, and an evaluation of market
     conditions.

     FEDERAL INCOME TAXES:  The Trust intends to comply with the requirements of
     the Internal Revenue Code applicable to regulated  investment companies and
     to distribute  all of its taxable and  tax-exempt  income to  shareholders;
     therefore, no federal income tax provision is required.

     SECURITIES  TRANSACTIONS:  Securities transactions are recorded on the date
     the  securities  are  purchased or sold (trade  date).  Realized  gains and
     losses on securities  transactions are determined on the basis of first-in,
     first-out for both financial statement and federal income tax purposes.

     DIVIDENDS TO  SHAREHOLDERS:  Distributions  to shareholders are recorded on
     the record date. The Equity Income Fund pays income dividends quarterly and
     capital gain dividends annually. The Fixed-Income and California Tax-Exempt
     Funds pay income dividends monthly and capital gain dividends annually.

     INVESTMENT  INCOME  AND  EXPENSES:  Dividend  income is  recognized  on the
     ex-dividend  date and interest  income is recognized  on an accrual  basis.
     Discounts and premiums on securities purchased are amortized over the lives
     of  the  respective  securities  using  the  constant  yield  method  which
     approximates  the  interest  method.  Expenses  are  recorded on an accrual
     basis.

     SECURITIES LENDING: The Equity Income Fund lends its securities to approved
     financial  institutions to earn additional  income and receives cash and/or
     securities as  collateral to secure the loans.  Collateral is maintained at
     not less than 102% of the value of loaned securities.  Although the risk of
     lending is mitigated by the collateral,  this fund could experience a delay
     in recovering  its securities and a possible loss of income or value if the
     borrower fails to return them.

THE PARNASSUS INCOME TRUST
- --------------------------------------------------------------------------------

     REPURCHASE AGREEMENTS:  Securities purchased with cash collateral held from
     securities lending may include investments in repurchase agreements secured
     by U.S. government  obligations or other securities.  Securities pledged as
     collateral for repurchase agreements are held by the Trust's custodian bank
     until maturity of the repurchase  agreements.  Provisions of the agreements
     ensure that the market value of the  collateral  is sufficient in the event
     of default;  however,  in the event of default or  bankruptcy  by the other
     party to the agreements, realization and/or retention of the collateral may
     be subject to legal proceedings.

     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 at the date of the financial
     statements  and the reported  amounts of revenues  and expenses  during the
     reporting period. Actual results could differ from those estimates.

2.   TAX MATTERS AND DISTRIBUTIONS

     Income  distributions  and capital gain  distributions  are  determined  in
     accordance  with income tax  regulations,  which may differ from accounting
     principles  generally  accepted  in the  United  States of  America.  These
     differences  are primarily due to differing  treatments of income and gains
     on various investment  securities held by the Trust, timing differences and
     differing characterization of distributions made by the Trust.

     Permanent  book-tax  differences,  if  any,  are  not  included  in  ending
     undistributed  net investment income (loss) for the purposes of calculating
     net investment income (loss) per share in the financial highlights.

     receive fees payable monthly, based on the Trust's average daily net assets
     for the month, at the following annual rates:

     EQUITY  INCOME  FUND:  0.75% of the  first  $30,000,000,  0.70% of the next

     AND CALIFORNIA  TAX-EXEMPT FUND: 0.50% of the first $200,000,000,  0.45% of
     the next $200,000,000 and 0.40% of the amount above $400,000,000.

     agreement  totaled  $2,265,633  for the six months ended June 30, 2004. For
     the six months ended June 30, 2004, Parnassus Investments has contractually
     agreed to reduce its  investment  advisory  fee to the extent  necessary to
     limit total operating  expenses to 0.87% of net assets for the Fixed-Income

THE PARNASSUS INCOME TRUST
================================================================================

     Under terms of a separate agreement which provides for furnishing  transfer
     agent  and fund  administration  services  to the  three  funds,  Parnassus
     Investments  received fees paid by the Trust totaling  $317,824 for the six
     months ended June 30, 2004.  The transfer agent fee was $2.70 per month per
     account.  The funds pay a monthly  fee based on the number of  accounts  on
     record at month-end.  The aggregate payment was $162,022 for the six months
     ended June 30, 2004. The fund  administration  fee was $25,967 per month in
     aggregate  for all three Funds (this amount is allocated  between the Funds
     based on net assets). The aggregate payment was $155,802 for the six months
     ended June 30, 2004.

     Jerome L. Dodson is the  president  of the Trust and is the  president  and
     majority stockholder of Parnassus Investments.

6.   GEOGRAPHIC AND INDUSTRY CONCENTRATION RISK FACTORS

     The California Tax-Exempt Fund primarily invests in debt obligations issued
     by the State of California  and its political  sub-divisions,  agencies and
     public  authorities to obtain funds for various public purposes.  There are
     certain risks arising from the  concentration  of investments in California
     municipal securities. The California Tax-Exempt Fund is more susceptible to
     factors adversely affecting issuers of California municipal securities than
     a fund  that is not  concentrated  in these  issuers  to the  same  extent.
     Uncertain economic  conditions or governmental  developments may affect the
     ability of California  municipal securities issuers to meet their financial
     obligations.
