                                     PART I

ITEM 1. BUSINESS

The Registrant is a publicly-held Limited Partnership organized under the
California Uniform Limited Partnership Act. In accordance with the Partnership
Agreement, the Registrant's General Partner is Del Taco, Inc., a California
corporation ("General Partner"). The Registrant sold 165,415 Units aggregating
$4,135,375 through an offering of Limited Partnership Units from June 5, 1987
through June 3, 1988.

The Registrant has engaged in the business of acquiring sites in California for
the construction of three Mexican-American restaurants for long-term lease to
Del Taco, Inc. for operation under the Del Taco trade name. Each Property is
leased for 32 years on a triple-net basis for a rent equal to twelve percent of
gross sales of the restaurant constructed thereon. The activities of the
Registrant relating to acquisition and development of the Properties is
presented under Item 2 below. The term of the Partnership Agreement is until
December 31, 2027 unless terminated earlier by means provided therein.

Because the three Properties owned by the Registrant constitute virtually all of
the Registrant's income producing assets, the business of the Registrant is
almost entirely dependent on the success of the Del Taco trade name restaurants
which lease those Properties. In turn, the success of those restaurants, which
are not operated by the Registrant, is dependent on a large variety of factors,
including, but not limited to, consumer demand and preference for fast food, in
general, and for Mexican-American food in particular.

The Registrant has no full time employees. The General Partner is vested with
full authority as to the general management and supervision of the business and
affairs of the Registrant, and has a one percent interest in the profits or
losses and distributions of the Registrant. Limited Partners have no right to
participate in the management or conduct of such business and affairs.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

Liquidity and Capital Resources

The Registrant commenced offering of Limited Partnership Units on June 5, 1987.
By June 3, 1988, the sale of such Units provided a total capitalization for the
Registrant of $4,135,375 including $1,000 attributable to the Special Limited
Partner. 14.5 percent of the cash received from the sale of Limited Partnership
Units was used to pay commissions to brokers and to reimburse the General
Partner for offering costs incurred. Approximately $3,000,000 of the remaining
funds were expended for the acquisition of sites and construction of three
restaurants. During 1989, the first restaurant opened for business. The two
additional restaurants commenced operation in 1990. In February 1992, the
Registrant distributed to Limited Partners of record on December 31, 1991
$442,270 of net proceeds not utilized as reserves and not invested in
properties.

Since the three restaurants owned by the Registrant opened, cash flow from lease
payments received from Del Taco, the Registrant's General Partner, which leases
all three restaurants, has provided adequate liquidity for operation of the
Registrant. However, the Registrant's overwhelmingly predominant source of
income to meet its expenses and fund distributions to its Limited Partners is
payments from Del Taco under the Leases, comprising primarily rent calculated on
the basis of the gross sales of the restaurants operated on the Properties, as
to which there are no contractually specified minimum or guaranteed amounts.
Thus, the adequacy of the Registrant's liquidity and capital resources in the
future will depend primarily upon the gross revenues of such restaurants as well
as upon Del Taco's financial condition and results of operations generally.

Results of Operations

The Registrant owns three Properties that are under long-term lease to Del Taco
for restaurant operations (Del Taco, in turn, has sub-leased one of the
restaurants to a Del Taco franchisee). The Registrant receives rental revenues
equal to 12 percent of restaurant sales. The Registrant had rental revenue of
$327,956 for the year ended December 31, 1997, representing a decrease from the
rental revenues of $361,980 in 1996. Such decrease is directly attributable to
the earning of supplemental rent in 1996.

The following table sets forth, for the periods indicated, the percentage
relationship to total general and administrative expenses of items included in
the Registrant's Statements of Income:

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



Operating expenses include general and administrative expenses which consist
primarily of accounting fees and costs of distribution of information to the
Limited Partners. For the years ended December 31, general and administrative
expenses decreased from $40,251 in 1996 to $38,951 in 1997 reflecting lower
costs for accounting and administration of the partnership. The Registrant
incurred depreciation expense of $103,748, $103,750 and $103,750 for each of the
years ended December 31, 1997, 1996 and 1995.

For the reasons stated under "Liquidity and Capital Resources" above, the
Registrant's result of operations in the future will depend primarily upon the
gross revenues of the restaurants located on the Properties leased to Del Taco
as well as upon Del Taco's financial condition and results of operations
generally.

Management does not believe the operations of the Company will be significantly
impacted by the year 2000 software issue and does not believe the year 2000
software issue will materially effect the Company's operations, financial
position or cash flows.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Partners of
 Del Taco Restaurant Properties, IV:


We have audited the accompanying balance sheets of DEL TACO RESTAURANT
PROPERTIES IV (a California limited partnership) as of December 31, 1997 and
1996, and the related statements of income, changes in partners' equity and cash
flows for each of three years in the period ended December 31, 1997. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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 audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Del Taco Restaurant Properties
IV as of December 31, 1997 and 1996, and the results of its operations and its
cash flows, for each of the three years in the period ended December 31, 1997,
in conformity with generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic financial
statements taken as a whole. The schedule in the index of financial statements
is presented for purposes of complying with the Securities and Exchange
Commissions rules and is not part of the basic financial statements. This
schedule has been subjected to the auditing procedures applied in the audit of

                                DECEMBER 31, 1997


NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

THE PARTNERSHIP: Del Taco Income Properties IV (a California limited
partnership) was formed on March 23, 1987, for the purpose of acquiring real
property in California for construction of three Mexican-American restaurants to
be leased under long-term agreements to Del Taco, Inc. (General Partner for
operation under the Del Taco trade name). As of July 13, 1990, all three
restaurants had commenced operation on acquired properties.

BASIS OF ACCOUNTING: The Partnership utilizes the accrual method of accounting
for transactions relating to the business of the Partnership. Distributions are
made to the General and Limited Partners in accordance with the provisions of
the Partnership Agreement (see Note 2).

PROPERTY AND EQUIPMENT: Property and equipment is stated at cost. Depreciation
is computed using the straight-line method over estimated useful lives which are
20 years for land improvements, 35 years for buildings and improvements, and 10
years for machinery and equipment.

In fiscal 1996, the Registrant adopted Statement of Financial Accounting
Standards (SFAS) No. 121, "Accounting for the Impairment of Long Lived Assets
and for Long Lived Assets to be Disposed of." SFAS 121 requires that long-lived
assets be reviewed for impairment whenever events or changes in circumstances
indicate that the carrying value of the asset may not be recoverable. In
evaluating long-lived assets held for use, an impairment loss is recognized if
the sum of the expected future cash flows (undiscounted and without interest
charges) is less than the carrying value of the asset. Once a determination has
been made that an impairment loss should be recognized for long-lived assets,
various assumptions and estimates are used to determine fair value including,
among others, estimated costs of construction and development, recent sales of
comparable properties and the opinions of fair value prepared by independent
real estate appraisers. Long-lived assets to be disposed of are reported at the
lower of carrying amount or fair value less cost to sell.

The adoption of SFAS No. 121 did not have a material effect on the Registrant's
financial statements.

INCOME TAXES: No provision has been made for federal or state income taxes on
Partnership net income, since the Partnership is not subject to income tax.
Partnership income is includable in the taxable income of the individual
partners as required under applicable income tax laws. Certain items, primarily
related to depreciation methods, are accounted for differently for income tax
reporting purposes (see Note 6).

NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES -
         CONTINUED

NET INCOME PER LIMITED PARTNERSHIP UNIT: Net income per Limited Partnership Unit
is calculated based upon 165,415 weighted average Units outstanding for all
years presented.

USE OF ESTIMATES: The preparation of the financial statements in conformity with
generally accepted accounting principles requires management to make certain
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.

NOTE 2 - PARTNERS' EQUITY

Pursuant to the Partnership Agreement, annual partnership net income or loss is
allocated one percent to the General Partner and 99 percent to the Limited
Partners. Partnership gains from any sale or refinancing will be allocated one
percent to the General Partner and 99 percent to the Limited Partners until
allocated gains and profits equal losses, distributions and syndication costs,
and until each class of Limited Partners receive their priority return as
defined in the Partnership Agreement. Additional gains will be allocated 12
percent to the General Partner and 88 percent to the Limited Partners.

NOTE 3 - SITE SELECTION AND DEVELOPMENT FEE

Under terms of the Partnership Agreement, the General Partner is entitled to
receive a fee in an amount equal to five percent of the gross proceeds of the
offering. The fee shall be for services rendered in connection with site
selection and the design and supervision of construction of improvements to
acquired properties. One percent of the gross proceeds of the offering has been
paid to the General Partner. The remaining four percent of this fee shall be
earned at the time the services are rendered, but shall not be paid and shall be
subordinated to the Limited Partners' interests until all restaurants have
opened and the Limited Partners have received certain minimum returns on their
investment, as required by the Partnership Agreement. It is the policy of the
Partnership to accrue the site selection and development fee as an obligation to
the General Partner. No fees were earned for such services during 1997, 1996 and
1995.

NOTE 4 - LEASING ACTIVITIES

The Registrant leases certain properties for operation of restaurants to Del
Taco, Inc. (General Partner) on a triple net basis. The leases are for terms of
32 years commencing with the completion of the restaurant facility located on
each property and require monthly rentals equal to 12 percent of the gross sales
of the restaurants. There is no minimum rental under any of the leases. The
Registrant had a total of three Properties leased to Del Taco as of December 31,
1997, 1996 and 1995 (Del Taco, in turn, has subleased one of the restaurants to
a Del Taco franchisee).

The two restaurants operated by Del Taco, for which the Registrant is the
lessor, had combined, unaudited sales of $1,523,099, $1,452,047, $1,491,715 and
unaudited net income of $76,600, $68,556 and $96,253 for the years ended
December 31, 1997, 1996 and 1995, respectively. Net income by restaurant
includes charges for general and administrative expenses incurred in connection
with supervision of restaurant operations and interest expense. The one
restaurant operated by a Del Taco franchisee, for which the Registrant is the
lessor, had unaudited sales of $874,554, $835,362 and $804,624 for the years
ended December 31, 1997, 1996 and 1995, respectively.

The Highland Avenue restaurant in Highland (San Bernardino), California had
unaudited net losses of $4,311, $14,043 and $10,904 for the years ended December
31, 1997, 1996 and 1995, respectively.

NOTE 5 - RELATED PARTIES

The receivable from Del Taco consists of rent accrued for the month of December
1997 as well as supplemental rent. These amounts were collected on January 17,
1998.

The General Partner received $2,848 in distributions relating to its one percent
interest in the Registrant for the year ended December 31, 1997.

Del Taco, Inc. serves in the capacity of general partner in other partnerships
which are engaged in the business of operating restaurants, and three other
partnerships which were formed for the purpose of acquiring real property in
California for construction of Mexican-American restaurants for lease under
long-term agreements to Del Taco, Inc. for operation under the Del Taco trade
name.
