Before you invest, you may want to review the Goldman Sachs Investor Tax-Exempt Money Market Fund’s (the “Fund”) Prospectus, which contains more information about the Fund and its risks. You can find the Fund’s Prospectus, reports to shareholders and other information about the Fund online at www.gsamfunds.com/moneymarketfunds. You can also get this information at no cost by calling 800-621-2550 or by sending an e-mail request to gs-funds-document-requests@gs.com. The Fund’s Prospectus and Statement of Additional Information (“SAI”), both dated December 27, 2019, are incorporated by reference into this Summary Prospectus.

It is our intention that beginning on January 1, 2021, paper copies of the Fund’s annual and semi-annual shareholder reports will not be sent by mail, unless you specifically request paper copies of the reports from the Fund or from your financial intermediary. Instead, the reports will be made available on a website, and you will be notified by mail each time a report is posted and provided with a website link to access the report.

If you already elected to receive shareholder reports electronically, you will not be affected by this change and you need not take any action. At any time, you may elect to receive reports and certain communications from the Fund electronically by calling the toll-free number below or by contacting your financial intermediary.

You may elect to receive all future shareholder reports in paper free of charge. If you hold shares of the Fund directly with the Fund’s transfer agent, you can inform the transfer agent that you wish to receive paper copies of reports by calling toll-free 800-621-2550. If you hold shares of the Fund through a financial intermediary, please contact your financial intermediary to make this election. Your election to receive reports in paper will apply to all Goldman Sachs Funds held in your account if you invest through your financial intermediary or all Goldman Sachs Funds held with the Fund’s transfer agent if you invest directly with the transfer agent.

2        SUMMARY PROSPECTUS — GOLDMAN SACHS INVESTOR TAX-EXEMPT MONEY MARKET FUND — CLASS I SHARES

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in Class I Shares of the Fund for the time periods indicated and then redeem all of your Class I Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the expense limitation arrangement for only the first year). The Example does not take into account brokerage commissions that you may pay on your purchases and sales of shares of the Fund. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

	1 Year	3 Years	5 Years	10 Years
Class I Shares	$        18	$        62	$        111	$        253

PRINCIPAL STRATEGY

The Fund pursues its investment objective by investing at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of investment) (“Net Assets”) in securities issued by or on behalf of states, territories and possessions of the United States and their political subdivisions, agencies, authorities and instrumentalities, and the District of Columbia, the interest from which, if any, is in the opinion of bond counsel excluded from gross income for federal income tax purposes, and generally not an item of tax preference under the federal alternative minimum tax (“AMT”). The Investment Adviser ordinarily expects 100% of the Fund’s assets will be invested in municipal obligations, but the Fund may invest in short-term taxable instruments, including repurchase agreements with the Federal Reserve Bank of New York, for temporary investment purposes.

The Fund intends to be a “retail money market fund,” as such term is defined in or interpreted under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”). “Retail money market funds” are money market funds that have policies and procedures reasonably designed to limit all beneficial owners of the fund to natural persons. As a “retail money market fund,” the Fund values its securities using the amortized cost method. The Fund seeks to maintain a stable net asset value (“NAV”) of $1.00 per share. Under Rule 2a-7, the Fund may invest only in U.S. dollar-denominated securities that meet certain risk-limiting conditions relating to portfolio quality, maturity, diversification and liquidity.

PRINCIPAL RISKS OF THE FUND

You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The Fund may impose a fee upon the sale of your shares or may temporarily suspend your ability to sell shares if the Fund’s liquidity falls below required minimums because of market conditions or other factors. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective.

Credit/Default Risk. An issuer or guarantor of a security held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. This also includes the risk of default on foreign letters of credit, guarantees or insurance policies that back municipal securities. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in NAV.

Geographic and Sector Risk. If the Fund invests a significant portion of its total assets in certain issuers within the same state, geographic region or economic sector, an adverse economic, business, political, environmental or other development affecting that state, region or sector may affect the value of the Fund’s investments more than if its investments were not so focused.

Interest Rate Risk. When interest rates increase, the Fund’s yield will tend to be lower than prevailing market rates, and the market value of its securities or instruments may also be adversely affected. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments. A low interest rate environment poses additional risks to the Fund, because low yields on the Fund’s portfolio holdings may have an adverse impact on the Fund’s ability to provide a positive yield to its shareholders, pay expenses out of Fund assets, or, at times, maintain a stable $1.00 share price. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

Large Shareholder Transactions Risk. The Fund may experience adverse effects when certain large shareholders (including financial intermediaries who may make investment decisions on behalf of underlying clients) purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly or unexpectedly, may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Liquidity Risk. The Fund may make investments that are illiquid or that may become less liquid in response to market developments or adverse investor perceptions. Illiquid investments may be more difficult to value. The liquidity of portfolio securities can deteriorate rapidly due to credit events affecting issuers or guarantors, such as a credit rating downgrade, or due to general market conditions or a lack of willing buyers. An inability to sell one or more portfolio positions, or selling such positions at an unfavorable time and/or under unfavorable conditions, can adversely affect the Fund’s ability to maintain a stable $1.00 share

price. Liquidity risk may also refer to the risk that the Fund will not be able to pay redemption proceeds within the allowable time period because of unusual market conditions, an unusually high volume of redemption requests, or other reasons. Liquidity risk may be the result of, among other things, the reduced number and capacity of traditional market participants to make a market in fixed income securities or the lack of an active market. The potential for liquidity risk may be magnified by a rising interest rate environment or other circumstances where investor redemptions from money market and other fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity.

Market Risk. The market value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Municipal Securities Risk. Municipal securities are subject to credit/default risk, interest rate risk and certain additional risks. The Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the debt securities of similar projects (such as those relating to education, health care, housing, transportation, and utilities), industrial development bonds, or in particular types of municipal securities (such as general obligation bonds, private activity bonds and moral obligation bonds). While interest earned on municipal securities is generally not subject to federal tax, any interest earned on taxable municipal securities is fully taxable at the federal level and may be subject to tax at the state level.

Stable NAV Risk. The Fund may not be able to maintain a stable $1.00 share price at all times. If any money market fund that intends to maintain a stable NAV fails to do so (or if there is a perceived threat of such a failure), other such money market funds, including the Fund, could be subject to increased redemption activity, which could adversely affect the Fund’s NAV. Shareholders of the Fund should not rely on or expect the Investment Adviser or an affiliate to purchase distressed assets from the Fund, make capital infusions into the Fund, enter into capital support agreements with the Fund or take other actions to help the Fund maintain a stable $1.00 share price.

Tax Risk. Future legislative or administrative changes or court decisions may materially affect the value of the Fund’s portfolio holdings and/or the ability of the Fund to pay federal tax-exempt dividends. The Fund would not be a suitable investment within IRAs, other tax-exempt or tax-deferred accounts, or for investors who are not sensitive to the federal tax consequences of their investments.

PORTFOLIO MANAGEMENT

Goldman Sachs Asset Management, L.P. is the investment adviser for the Fund (the “Investment Adviser” or “GSAM”).

BUYING AND SELLING FUND SHARES

Investments in the Fund are limited to accounts beneficially owned by natural persons. Generally, Class I Shares may be purchased only through certain intermediaries that have a relationship with Goldman Sachs & Co. LLC (“Goldman Sachs”), including banks, trust companies, brokers, registered investment advisers and other financial institutions (“Intermediaries”). The minimum initial investment requirement imposed upon Intermediaries for the purchase of Class I Shares is generally $10 million, and there is no minimum imposed upon additional investments. Intermediaries may, however, impose a minimum amount for initial and additional investments in Class I Shares, and may establish other requirements such as a minimum account balance.

You may purchase and redeem (sell) shares of the Fund on any business day through an Intermediary.

TAX INFORMATION

The Fund’s distributions that are designated as “exempt interest dividends” are generally not subject to federal income tax. To the extent that Fund distributions are attributable to interest on certain federal obligations or interest on obligations of your state of residence or its municipalities or authorities, they will in most cases be exempt from state and local income taxes. The Fund intends to avoid investments which pay interest that is a preference item in determining AMT liability.

PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES

If you purchase the Fund through an Intermediary, the Fund and/or its related companies may pay the Intermediary for the sale of Fund shares and related services. These payments may create a conflict of interest by influencing the Intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your Intermediary’s website for more information.
