Letter to Shareholders
 
- ---------------------------------------  ---------------------------------------
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 Money Market
Trust/Financial Square Funds in 1998. It was another strong year for the funds,
during which all of them outperformed their respective IBC Financial Data, Inc.
averages. Net assets in the Financial Square Funds totaled $27.5 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 fund's 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 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 averse
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.

  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 Funds 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 funds' WAMs to the 40- to 50-
day range. This decision helped keep the funds' yields competitive during this
period of high cash inflows and high demand for municipal securities. In March,
we shortened the WAMs of the funds 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 funds' WAMs to the 40-day
range.
  At period end, after a brief period during which the funds' 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).

*Financial Square Funds offer four separate classes of shares (Institutional,
Preferred, Administration and Service), each of which is subject to different
fees and expenses that affect performance and entitle shareholders to different
services. The Preferred, Administration and Service shares offer financial
institutions the opportunity to receive a fee for providing administrative
support services. The Preferred shares pay 0.10%, Administration shares pay
0.25%, and the Service shares pay 0.50%. If these fees were reflected in the
above performance, performance would be reduced. Past performance is no
guarantee of future results. Yields will vary. An investment in any one of the
Financial Square Funds is neither insured nor guaranteed by the U.S. Government
nor is there any assurance that the Funds will be able to maintain a stable net
asset value of $1.00 per share. More complete information, including management
fees and expenses, is included in the funds' prospectus or may be obtained by
calling Goldman Sachs Funds at 1-800-621-2550.
 
Outlook and Strategies for 1999
  With the financing pressure of year-end behind institutional investors, we
are looking to extend the funds' 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 economists anticipate that easing will come later
rather 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 Financial Square money market funds. 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 productive year in 1999.

Goldman Sachs Trust--Financial Square Funds
- --------------------------------------------------------------------------------
Notes to Financial Statements
December 31, 1998
- ---------------------------------------  ---------------------------------------
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 Financial Square Funds, collectively
"the Funds" or individually a "Fund". Financial Square consists of nine
diversified funds: Prime Obligations, Money Market, Premium Money Market,
Treasury Obligations, Treasury Instruments, Government, Federal, Tax-Free Money
Market and Municipal Money Market (inactive as of December 31, 1998). The
Financial Square Funds offer four classes of shares: FST shares, FST Preferred
shares, FST Administration shares and FST Service shares. The investment
objective of the Funds is to maximize current income to the extent consistent
with the preservation of capital and maintenance of liquidity. In addition, the
Tax-Free Money Market Fund seeks to provide shareholders with a high level of
income exempt from federal income tax.
 
2. Significant Accounting Policies
The following is a summary of significant accounting policies consistently
followed by the Funds. 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--
Each Fund 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 Fund'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
shareholders. Accordingly, no federal tax provisions are required.
 The characterization of distributions to shareholders for financial reporting
purposes is determined in accordance with federal income tax rules. Therefore,
the source of the Funds' 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 fund had a capital loss
carryforward for U.S. Federal tax purposes of approximately:

       Fund                                                  Amount  Expiration
       ----                                                  ------- ----------
<S>                                                          <C>     <C>
Tax-Free Money Market....................................... $11,000 2003-2005
</TABLE>
 
This amount is available to be carried forward to offset future capital gains
to the extent permitted by applicable laws or regulations.
 
D. Deferred Organization Expenses--
Organization-related costs are amortized on a straight-line basis over a period
of five years.
 
E. Expenses--
Expenses incurred by the Funds that do not specifically relate to an individual
fund are generally allocated to the Funds based on the nature of the expense.
 Shareholders of FST Preferred, FST Administration and FST Service shares bear
all expenses and fees paid to service organizations for their services with
respect to such shares.

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 general supervision by the Trust's Board
of Trustees, manages the Funds' portfolios and administers each Fund'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 .205% of each Fund's average daily net assets.
 For the year ended December 31, 1998, GSAM has voluntarily agreed to waive a
portion of its management fee. In addition, GSAM has limited certain of each of
the Fund's expenses (excluding management fees, service organization fees,
taxes, interest, brokerage commissions, litigation, indemnification and other
extraordinary expenses) to the extent that such expenses exceed .01% per annum
of each Fund's average daily net assets.
 Goldman Sachs serves as Transfer Agent and Distributor of shares of the Funds
pursuant to Transfer Agent and Distribution Agreements and receives no separate
fee.
 The following chart outlines the fee waivers and expense reimbursements for
the year ended December 31, 1998 (in thousands):

4. Preferred, Administration and Service Plans
The Funds have adopted Preferred, Administration and Service Plans to
compensate service organizations for providing varying levels of account
administration and shareholder liaison services to their customers who are
beneficial owners of such shares. The Preferred, Administration and Service
Plans provide for compensation to the service organizations in an amount up to
 .10%, .25% and .50% (on an annualized basis), respectively, of the average
daily net asset value of the respective shares.

5.Line of Credit Facility
The Funds participate 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 Fund 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, the Funds 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 at a custodian.
 
7.Joint Repurchase Agreement Accounts
The Funds, together with other registered investment companies having
management agreements with GSAM or its affiliates, 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, Premium Money
Market, Treasury Obligations and Government Funds had undivided interests in
the repurchase agreements held in the following joint account, which equaled
$201,300,000, $36,200,000, $182,800,000, $1,678,200,000 and $314,000,000 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 Shareholders and Board of Trustees of
Goldman Sachs Trust--Financial Square Funds:
 
 We have audited the accompanying statements of assets and liabilities of
Goldman Sachs Trust--Financial Square Funds (a Delaware Business Trust
comprising the Prime Obligations, Money Market, Premium Money Market, Treasury
Obligations, Treasury Instruments, Government, Federal and Tax-Free Money
Market Funds), including the statements of investments, as of December 31,
1998, and the related statements of operations 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
Funds' 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 financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective Funds constituting Goldman Sachs Trust--Financial Square
Funds as of December 31, 1998, the results of their operations and the changes
in their net assets and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.
