Dear Shareholders:
 
  We welcome this opportunity to provide you with a summary of the trends and
key events that affected the economy and the Goldman Sachs Institutional
Liquid Assets (ILA) Portfolios in 1998. It was another strong year for the
funds, during which all of the portfolios outperformed or performed in line
with their respective IBC Financial Data, Inc. averages. Net assets in the ILA
Portfolios totaled $10.5 billion as of December 31, 1998.
 
The Economy In Review
  Despite a slight tempering due to soft employment numbers, the U.S. economy
continued to see strong growth for most of 1998. This growth, combined with
continued uncertainty about the impact of Asian instability on the U.S.
economy, kept the Federal Reserve in a wait-and-see mode for the first nine
months of the year.
  On September 29th, in the wake of increasing global market turmoil, the
Federal Reserve Board cut the Federal Funds target rate by 25 basis points, to
5.25%. As increasing illiquidity concerns in the market became more severe,
the Fed followed up with two more surprise rate cuts, easing the target rate
and the discount rate by another 50 basis points.
  The Fed's moves were a strong signal that the monetary authorities were
prepared to do whatever was necessary to provide liquidity and to support the
economy against the forces that had the potential of a substantial economic
slowdown in 1999.
  At period end, while consumer spending remained strong, the manufacturing
side of the economy appeared to weaken because of a trade drag and a slowdown
in capital spending. However, based on signs of non-inflationary growth in the
areas of consumer spending, new home sales and strong third quarter gross
domestic product (GDP), the general consensus is that any further easing by
the Fed will come later, rather than sooner.
 
Credit Year 1998: A Year of Crisis with a Hopeful Ending
  Domestic credit quality continued its strong positive trend for the first
six months of 1998. Mergers and acquisitions were at an all time high. U.S.
banks remained strong, well capitalized and provisioned, with diversified
operations. The stock market continued its climb and American consumers were
spending more than they were earning. The shocks of the Russian default in
August and the near collapse of Long Term Capital Management (LTCM) caused
severe liquidity problems and a difficult trading environment, as well as a
major sell-off in the stock market. Calm was restored by the rescue of LTCM
and the Fed's lowering of interest rates three times in seven weeks. A newly
risk adverse investor moved funds to safer, more liquid credits. The
enthusiasm for globalization was temporarily curbed, as domestic production
was suppressed in response to the Asian crisis and corporate profit gains for
the year were generally mixed.
  The international credit environment in 1998 saw the Asian situation explode
into a full-blown global crisis that adversely affected markets around the
world. The default and devaluation of Russia in August came after an already
painful several months of recession and restructuring in Asia. This pain was
exacerbated by Japan's continued slow economic deterioration, which cast a
shadow over the entire region. The unprecedented market volatility that
followed Russia's default took months to dissipate, and only after a more
committed response by the U.S. government to the crisis. By the end of the
year, however, trends were much more positive. The reforming Asian economies
showed notable progress, with signs of a return to economic growth in 1999.
More significant, however, was the successful launch of the euro. Ongoing
policy convergence and political resolution served to create the world's first
regional currency with nary a ripple in the markets. In fact, with the U.S.
economy seemingly impervious to difficulties elsewhere, global markets quickly
rebounded to close the year on a decidedly positive note.

Letter to Unit/Shareholders (continued)
- ---------------------------------------  ---------------------------------------
  Although the U.S. economy remains favorable, the challenges of global
volatility continue to concern us. The Goldman Sachs Credit Department, with
analysts based in London, Tokyo, Frankfurt and New York, as well as extensive
technological assets and credit expertise, will continue to anticipate and
monitor global developments and apply its conservative credit standards to the
money market portfolios.
 
Strategy
  Taxable--For most of the period, a "flight to quality" resulting from the
ongoing Asian economic crisis rendered the short end of the yield curve
expensive. In view of this, the Portfolios maintained a neutral stance by
buying on market dips and "aging in" when levels got expensive. However, we
extended the weighted average maturity (WAM) ranges from neutral to slightly
long as the Fed began its series of easings in late September in response to
market liquidity. We continued to maintain a barbell structure by holding
significant liquidity in anticipation of year-end outflows, and targeted longer
dated maturities to enhance performance in a declining rate environment.
  Tax-Exempt--Early in the period, given the fact that we no longer foresaw a
near-term Fed easing and in preparation for the seasonally short supply of
municipal issuance in January, we increased the portfolio's WAMs to the 40- to
50-day range. This decision helped keep the portfolios' yields competitive
during this period of high cash inflows and high demand for municipal
securities. In March, we shortened the WAMs of the portfolios to the 30- to 35-
day range, seeking to build liquidity as the April 15th tax deadline
approached. This move helped us to fund tax-time redemptions. In August, when
seasonal issuance was strong and there was less demand in the tax-exempt market
in contrast to the "flight to quality" in the Treasury market, we extended the
portfolios' WAMs to the 40-day range.
  At period end, after a brief period during which the portfolios' WAMs were
brought into a neutral range, we extended the WAMs in anticipation of
technically driven lower yields (due to inflows from the reinvestment of
maturity proceeds, coupled with a seasonal scarcity of issuance).

*ILA offers four separate classes of units/shares (Institutional,
Administration, Service and Cash Management), each of which is subject to
different fees and expenses that affect performance and entitle
unit/shareholders to different services. The Administration and Service units
offer financial institutions the opportunity to receive a fee for providing
administrative support services. The Administration units pay 0.15% plus 0.10%
from the adviser for a total of 0.25%. The Service units pay 0.40% plus 0.10%
from the adviser for a total of 0.50%. The Cash Management shares pay 0.50%
plus 0.30% from the adviser for a total of up to 0.80%. Furthermore, in
addition to these classes, Prime Obligations offers Class B and Class C units,
which may be subject to contingent deferred sales charges. More complete
information, including management fees and expenses, is included in the ILA
Portfolios' prospectus or may be obtained by calling Goldman Sachs Funds at

Outlook and Strategies for 1999
  With the financing pressure of year-end behind institutional investors, we
are looking to extend the portfolios' weighted average maturities somewhat as
we see opportunities on the yield curve. While there are a

variety of opinions as to when the Fed will move, based on current signs of
non-inflationary growth in areas of consumer spending, new home sales and
fourth quarter GDP, most anticipate that easing will come later than sooner.
Goldman Sachs economists' 1999 outlook anticipates a 50 basis point cumulative
ease in the second half of the year.
  In closing, we thank you for your support and for making 1998 a year of
record assets for the ILA money market portfolios. As in the past, we will
continue to look for additional ways to improve our services, while seeking to
provide you with competitive performance. We welcome your suggestions and
questions, and look forward to another strong year in 1999.

1. Organization
The Goldman Sachs Trust (the "Trust") is a Delaware business trust registered
under the Investment Company Act of 1940 (as amended) as an open-end management
investment company. The Trust includes the Goldman Sachs--Institutional Liquid
Assets Portfolios, collectively "ILA". ILA consists of nine portfolios: Prime
Obligations, Money Market, Government, Treasury Obligations, Treasury
Instruments, Federal, Tax-Exempt Diversified, Tax-Exempt California and Tax-
Exempt New York. All of the portfolios are diversified except for the Tax-
Exempt California and Tax-Exempt New York Portfolios. ILA offers the following
classes:

The investment objective of the portfolios is to maximize current income to the
extent consistent with the preservation of capital and maintenance of
liquidity. The Tax-Exempt Diversified, Tax-Exempt California and Tax-Exempt New
York Portfolios also seek to provide shareholders with a high level of income
exempt from federal income tax. In addition, the Tax-Exempt California and Tax-
Exempt New York Portfolios seek to provide shareholders with income exempt from
California state and New York state and city personal income taxes,
respectively.
 
2. Significant Accounting Policies
The following is a summary of significant accounting policies consistently
followed by ILA. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that may affect the reported amounts.
 
A. Investment Valuation--
ILA uses the amortized-cost method for valuing portfolio securities, which
approximates market value. Under this method, all investments purchased at a
discount or premium are valued by amortizing the difference between the
original purchase price and maturity value of the issue over the period to
maturity.
 
B. Interest Income--
Interest income is determined on the basis of interest accrued, premium
amortized and discount earned.
 
C. Federal Taxes--
It is each portfolio's policy to comply with the requirements of the Internal
Revenue Code applicable to regulated investment companies and to distribute
each year substantially all investment company taxable and tax-exempt income to
its unitholders. Accordingly, no federal tax provisions are required.
 The characterization of distributions to unit/shareholders for financial
reporting purposes is determined in accordance with federal income tax rules.
Therefore, the source of the portfolios' distributions may be shown in the
accompanying financial statements as either from or in excess of net investment
income or net realized gain on investment transactions, or from paid-in
capital, depending on the type of book/tax differences that may exist.
 At December 31, 1998 (tax year end), the following portfolios had capital loss
carryforwards for U.S. Federal tax purposes of approximately:
 
<TABLE>

   ---------            -------- ------------
<S>                     <C>      <C>
Tax-Exempt Diversified  $144,593 2001 to 2005
Tax-Exempt New York        4,673 1999 to 2004

- --------------------------------------------------------------------------------
- ---------------------------------------  ---------------------------------------
2. Significant Accounting Policies (continued)
 These amounts are available to be carried forward to offset future capital
gains to the extent permitted by applicable laws or regulations.
 
D. Expenses--
Expenses incurred by ILA which do not specifically relate to an individual
portfolio of ILA are generally allocated to the portfolios based on the nature
of the expense.
 Unitholders of ILA Administration, ILA Service, ILA B, ILA C and Cash
Management share classes bear all expenses and fees paid to service and
distribution organizations for their services with respect to such classes as
well as other expenses (subject to expense limitations) which are directly
attributable to such classes. Effective September 1, 1998, each class of
units/shares of the Portfolios now separately bears its respective class-
specific transfer agency fees.
 
3. Agreements
Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co. ("Goldman Sachs"), acts as investment adviser (the
"Adviser") pursuant to an Investment Management Agreement (the "Agreement").
Under the Agreement, GSAM, subject to the general supervision by the Trust's
Board of Trustees, manages the portfolios and administers each portfolio's
business affairs, including providing facilities. As compensation for the
services rendered under the Agreement and the assumption of the expenses
related thereto, GSAM is entitled to a fee, computed daily and payable monthly,
at an annual rate equal to .35% of each portfolio's average daily net assets.
For the year ended December 31, 1998, GSAM has voluntarily agreed to waive a
portion of its management fees for the Money Market, Treasury Instruments,
Federal, Tax-Exempt Diversified and Tax-Exempt New York Portfolios,
respectively.
 Goldman Sachs acts as ILA's distributor under a Distribution Agreement for
which it receives no compensation except for a portion of the ILA Prime
Obligations Class B and Class C contingent deferred sales charges. Goldman
Sachs has advised the Portfolio that it retained approximately $2,000 for the
period ended December 31, 1998.
 GSAM had voluntarily agreed to reduce or limit the total operating expenses of
each Portfolio (excluding distribution and service fees, administration and
service plan fees, taxes, interest, brokerage commissions, litigation,
indemnification and other extraordinary expenses) on an annualized basis to
approximately .43% of the average net assets of each portfolio.
 For the year ended December 31, 1998, the Adviser waived certain fees and
expenses such that annualized "Management Fees", "Other Expenses (including
transfer agent fees)" and "Total Operating Expenses" (as defined above)
actually incurred by the portfolios based on average net assets were as
follows:

 The ILA Class B Units, ILA Class C Units and Cash Management Shares have each
adopted a Distribution Plan (the "Distribution Plan") pursuant to Rule 12b-1.
Under the Distribution Plan, Goldman Sachs is entitled to a quarterly fee for
distribution services equal, on an annual basis, of up to .75% of the average
daily net assets attributable to ILA Class B Units and ILA Class C Units and
 .50% of the average daily net assets attributable to Cash Management Shares.
For the period ended December 31, 1998, GSAM has voluntarily agreed to

waive a portion of the Cash Management Shares Distribution Fees.
 The ILA Class B Units and ILA Class C Units of Prime Obligations Portfolio had
also adopted an Authorized Dealer Service Plan (the "Dealer Service Plan")
pursuant to which Goldman Sachs and Authorized Dealers are compensated for
providing personal and account maintenance services. ILA Class B Units and ILA
Class C Units pay a fee under this Dealer Service Plan equal, on an annual
basis, to .25% of ILA Class B and Class C units' average daily net assets.
 Effective September 1, 1998, the Distribution Plans and Dealer Service Plans
were combined into Distribution and Service Plans. Under the Distribution and
Service Plans, Goldman Sachs and/or Authorized Dealers are entitled to a
monthly fee from each Portfolio for distribution services equal to, on an
annual basis, 1.00% of the average daily net assets attributable to Class B and
Class C units and 50% of the average daily net assets attributable to Cash
Management shares.
 Goldman Sachs also serves as the Transfer Agent and is entitled to a fee
calculated daily and payable monthly at an annual rate of .04% of the average
daily net assets of each class.

4. Administration, Service and Cash Management Plans
ILA has adopted Administration and Service Plans. These plans allow for ILA
Administration Units, ILA Service Units and Cash Management Shares,
respectively, to compensate service organizations for providing varying levels
of account administration and unitholder liaison services to their customers
who are beneficial owners of such units. The Administration, Service and Cash
Management Shares Plans provide for compensation to the service organizations
in an amount up to .15%, .40% and .50% (on an annualized basis), respectively,
of the average daily net asset value of the respective units/shares.
 
5. Line of Credit Facility
ILA participates in a $250,000,000 uncommitted, unsecured revolving line of
credit facility to be used solely for temporary or emergency purposes. Under
the most restrictive arrangement, each Portfolio must own securities having a
market value in excess of 300% of the total bank borrowings. The interest rate
on the borrowings is based on the Federal Funds rate. During the year ended
December 31, 1998, ILA did not have any borrowings under this facility.

6. Repurchase Agreements
During the term of a repurchase agreement, the value of the underlying
securities, including accrued interest, is required to equal or exceed the
value of the repurchase agreement. The underlying securities for all repurchase
agreements are held in safekeeping by a custodian.
 
7. Joint Repurchase Agreement Accounts
The ILA Portfolios, together with other registered investment companies having
management agreements with GSAM or its affiliates, may transfer uninvested cash
balances into joint accounts, the daily aggregate balances of which are
invested in one or more repurchase agreements.
 At December 31, 1998, the Prime Obligations, Money Market, Government and
Treasury Obligations Portfolios had investments in the following joint
repurchase account of $123,400,000, $68,900,000, $95,400,000 and $294,200,000
in principal amount, respectively. At December 31, 1998, the repurchase
agreements held in this joint account were fully collateralized by U.S.
Treasury obligations.

Report of Independent Public Accountants
- ---------------------------------------  ---------------------------------------
To the Unit/Shareholders and Board of Trustees of the Goldman Sachs Trust--
Institutional Liquid Assets Portfolios:
 
 We have audited the accompanying statements of assets and liabilities of
Goldman Sachs Trust--Institutional Liquid Assets (a Delaware Business Trust
comprising the Prime Obligations, Money Market, Government, Treasury
Obligations, Treasury Instruments, Federal, Tax-Exempt Diversified, Tax-Exempt
California and Tax-Exempt New York Portfolios), including the statements of
investments as of December 31, 1998, and the related statements of operations
for the year then ended, and the statements of changes in net assets and the
financial highlights for the periods presented. These financial statements and
the financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and the
financial highlights 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 and the financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights. Our procedures included confirmation of
securities owned as of December 31, 1998 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 audits provide a
reasonable basis for our opinion.
 
 In our opinion, the financial statements and the financial highlights referred
to above present fairly, in all material respects, the financial position of
each of the respective portfolios constituting Goldman Sachs Trust--
Institutional Liquid Assets as of December 31, 1998, the results of their
operations for the year then ended, the changes in their net assets and the
financial highlights for the periods presented, in conformity with generally
accepted accounting principles.
