Risk/Return [Heading]	rr_RiskReturnHeading	Goldman Sachs Government Income Fund—Summary
Objective [Heading]	rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Goldman Sachs Government Income Fund (the “Fund”) seeks a high level of current income, consistent with safety of principal.
Expense [Heading]	rr_ExpenseHeading	Fees and Expenses of the Fund
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $100,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 59 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 63 and in “Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts” on page 106 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-122 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended March 31, 2017 was 441% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	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 A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T 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 fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in securities issued or guaranteed by the U.S. Government, its agencies, instrumentalities or sponsored enterprises (“U.S. Government Securities”) and in repurchase agreements collateralized by such securities. The remainder of the Fund’s Net Assets may be invested in non-government securities such as privately issued adjustable rate and fixed rate mortgage loans or other mortgage-related securities (“Mortgage-Backed Securities”), asset-backed securities and corporate securities. The Fund also intends to invest in derivatives, including (but not limited to) futures, swaps, options on swaps and other derivative instruments, which are used primarily to hedge the Fund’s portfolio risks, manage the Fund’s duration and/or gain exposure to certain fixed income securities. 100% of the Fund’s portfolio will be invested in U.S. dollar-denominated securities. The Fund’s investments in non-U.S. Government Securities must be rated AAA or Aaa by a nationally recognized statistical rating organization (“NRSRO”) at the time of purchase, or, if unrated, must be determined by the Investment Adviser to be of comparable credit quality. The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the Bloomberg Barclays U.S. Government/Mortgage Index, plus or minus one year, and over the past five years ended June 30, 2017, the duration of this index has ranged between 3.94 and 5.34 years. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price. The Fund’s benchmark index is the Bloomberg Barclays U.S. Government/Mortgage Index. GSAM’s Fixed Income Investing Philosophy: Global fixed income markets are constantly evolving and are highly diverse—with a large number of countries, currencies, sectors, issuers and securities. We believe that inefficiencies in these complex markets cause bond prices to diverge from their fair value. To capitalize on these inefficiencies and generate consistent risk-adjusted performance, we believe it is critical to: Thoughtfully combine diversified sources of return by employing multiple strategies Take a global perspective to uncover relative value opportunities Employ focused specialist teams to identify short-term mis-pricings and incorporate long-term views Emphasize a risk-aware approach as we view risk management as both an offensive and defensive tool Build a strong team of skilled investors who excel on behalf of our clients
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. 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. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Call/Prepayment Risk.  An issuer could exercise its right to pay principal on an obligation held by the Fund (such as a Mortgage-Backed Security) earlier than expected. This may happen when there is a decline in interest rates, when credit spreads change, or when an issuer’s credit quality improves. Under these circumstances, the Fund may be unable to recoup all of its initial investment and will also suffer from having to reinvest in lower-yielding securities. Credit/Default Risk.  An issuer or guarantor of fixed income securities or instruments held by the Fund may default on its obligation to pay interest and repay principal or default on any other obligation. Additionally, the credit quality of securities may deteriorate rapidly, which may impair the Fund’s liquidity and cause significant deterioration in net asset value (“NAV”). Derivatives Risk.  The Fund’s use of futures, swaps, options on swaps and other derivative instruments may result in losses. These instruments, which may pose risks in addition to and greater than those associated with investing directly in securities, currencies or other instruments may be illiquid or less liquid, volatile, difficult to price and leveraged so that small changes in the value of underlying instruments may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party in the transaction will not fulfill its contractual obligation. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments. In December 2015, the Securities and Exchange Commission (“SEC”) proposed new regulations relating to a mutual fund’s use of derivatives and related instruments. If these or other regulations are adopted, they could significantly limit or impact a Fund’s ability to invest in derivatives and other instruments and adversely affect such Fund’s performance and ability to pursue its investment objectives. Interest Rate Risk.  When interest rates increase, fixed income securities or instruments held by the Fund will generally decline in value. Long-term fixed income securities or instruments will normally have more price volatility because of this risk than short-term fixed income securities or instruments. The risks associated with increasing interest rates are heightened given that interest rates are near historic lows, but may be expected to increase in the future with unpredictable effects on the markets and the Fund’s investments. 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 purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions 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 and is required to maintain 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. Mortgage-Backed and/or Other Asset-Backed Securities Risk.  Mortgage-related and other asset-backed securities are subject to certain additional risks, including “extension risk” (i.e., in periods of rising interest rates, issuers may pay principal later than expected) and “prepayment risk” (i.e., in periods of declining interest rates, issuers may pay principal more quickly than expected, causing the Fund to reinvest proceeds at lower prevailing interest rates). Mortgage-Backed Securities offered by non-governmental issuers are subject to other risks as well, including failures of private insurers to meet their obligations and unexpectedly high rates of default on the mortgages backing the securities. Other asset-backed securities are subject to risks similar to those associated with Mortgage-Backed Securities, as well as risks associated with the nature and servicing of the assets backing the securities. Asset-backed securities may not have the benefit of a security interest in collateral comparable to that of mortgage assets, resulting in additional credit risk. U.S. Government Securities Risk.  The U.S. government may not provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. U.S. Government Securities issued by those agencies, instrumentalities and government sponsored enterprises, including those issued by the Federal National Mortgage Association (“Fannie Mae”), Federal Home Loan Mortgage Corporation (“Freddie Mac”) and the Federal Home Loan Banks are neither issued nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. The maximum potential liability of the issuers of some U.S. Government Securities held by the Fund may greatly exceed their current resources, including any legal right to support from the U.S. Treasury. It is possible that issuers of U.S. Government Securities will not have the funds to meet their payment obligations in the future.

[1] A contingent deferred sales charge ("CDSC") of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund's "Management Fees" have been restated to reflect current fees.

[3] The "Other Expenses" for Class R6 Shares have been restated and the "Other Expenses" for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to: (i) reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, shareholder meeting, litigation, indemnification and extraordinary expenses) to 0.004% of the Fund's average daily net assets; and (ii) waive a portion of its management fee payable by the Fund in an amount equal to any management fee it earns as an investment adviser to any of the affiliated funds in which the Fund invests. These arrangements will remain in effect through at least July 28, 2018, and prior to such date the Investment Adviser may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.
