Goldman Sachs Short Duration Tax-Free Fund
Risk/Return:		rr_RiskReturnAbstract
Risk/Return [Heading]		rr_RiskReturnHeading	Goldman Sachs Short Duration Tax-Free Fund—Summary
Objective [Heading]		rr_ObjectiveHeading	Investment Objective
Objective, Primary [Text Block]		rr_ObjectivePrimaryTextBlock	The Goldman Sachs Short Duration Tax-Free Fund (the “Fund”) seeks a high level of current income, consistent with relatively low volatility of principal, that is exempt from regular federal income tax.
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 Shares if you and your family invest, or agree to invest in the future, at least $500,000 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 37 of this Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-124 of the Fund’s Statement of Additional Information (“SAI”).
Shareholder Fees Caption [Text]		rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]		rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Fee Waiver or Reimbursement over Assets, Date of Termination		rr_FeeWaiverOrReimbursementOverAssetsDateOfTermination	July 29, 2016
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, 2015 was 24% of the average value of its portfolio.
Portfolio Turnover, Rate		rr_PortfolioTurnoverRate	24.00%
Expenses Deferred Charges [Text Block]		rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge (“CDSC”) of 0.65% is imposed on Class C Shares redeemed within 12 months of purchase.
Expense Breakpoint Discounts [Text]		rr_ExpenseBreakpointDiscounts	You may qualify for sales charge discounts on purchases of Class A Shares if you and your family invest, or agree to invest in the future, at least $500,000 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 37 of this Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-124 of the Fund’s Statement of Additional Information (“SAI”).

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 and/or Class IR Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service and/or Class IR 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:
Expense Example by, Year, Caption [Text]		rr_ExpenseExampleByYearCaption	Assuming complete redemption at end of period
Expense Example, No Redemption, By Year, Caption [Text]		rr_ExpenseExampleNoRedemptionByYearCaption	Assuming no redemption
Strategy [Heading]		rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]		rr_StrategyNarrativeTextBlock	The Fund invests, under normal market conditions, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in fixed income securities issued by or on behalf of states, territories and possessions of the United States (including the District of Columbia) and the political subdivisions, agencies and instrumentalities thereof (“Municipal Securities”), the interest on which is exempt from regular federal income tax (i.e., excluded from gross income for federal income tax purposes), and is not a tax preference item under the federal alternative minimum tax. Under normal market conditions, the Fund’s investments in private activity bonds and taxable investments will not exceed, in the aggregate, 20% of the Fund’s Net Assets. The interest from private activity bonds (including the Fund’s distributions of such interest) may be a preference item for purposes of the federal alternative minimum tax. 100% of the Fund’s portfolio will be invested in U.S. dollar-denominated securities. The team uses a multi-faceted approach when evaluating whether to add or maintain exposure to any individual position. A top-down approach is used to assess broad macro trends while a bottom-up analysis is used to determine relative value between individual securities. Individual securities will be considered for purchase or sale based on credit profile, risk, structure, pricing, and portfolio impact, as well as duration management, restructuring, opportunistic trading and tax loss harvesting. Under normal interest rate conditions, the Fund’s duration is expected to approximate that of the Barclays Municipal 1-3 Year Blend Index, plus or minus 0.5 years. (Historically, over the last ten years, the duration of the Barclays Municipal 1-3 Year Blend Index has ranged between 2.01 and 2.71 years). The reference to “Short Duration” in the Fund’s name refers to this duration. “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 Barclays Municipal 1-3 Year Blend Index.
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. Concentration Risk.  If the Fund concentrates its investments in issuers within the same country, state or economic sector, an adverse economic, business or political development may affect the value of the Fund’s investments more than if its investments were not so concentrated. Credit/Default Risk.  An issuer or guarantor of fixed income securities 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 net asset value (“NAV”) deterioration. These risks are more pronounced in connection with the Fund’s investments in non-investment grade fixed income securities. 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. 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. 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. 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. To meet redemption requests, the Fund may be forced to sell securities at an unfavorable time and/or under unfavorable conditions. 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 fixed income mutual funds may be higher than normal, potentially causing increased supply in the market due to selling activity. Market Risk.  The 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 bonds 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). State Specific Risk.  The Fund’s investments in municipal obligations of issuers located in a particular state may be adversely affected by political, economic and regulatory developments within that state. Such developments may affect the financial condition of a state’s political subdivisions, agencies, instrumentalities and public authorities and heighten the risks associated with investing in bonds issued by such parties, which could, in turn, adversely affect the Fund’s income, NAV, liquidity, and/or ability to preserve or realize capital appreciation. Tax Risk.  Any proposed or actual changes in income tax rates or the tax-exempt status of interest income from Municipal Securities can significantly affect the demand for and supply, liquidity and marketability of Municipal Securities. Such changes may affect the Fund’s net asset value and ability to acquire and dispose of Municipal Securities at desirable yield and price levels.

[1] A contingent deferred sales charge ("CDSC") of 0.65% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The differences in the "Other Expenses" ratios across the share classes are the result of, among other things, contractual differences in transfer agency fees and the effect of mathematical rounding on the daily accrual of certain expenses, particularly in respect of small share classes.

[3] The Investment Adviser has agreed to (i) waive a portion of its Management Fee in order to achieve an effective rate of 0.35% as an annual percentage rate of average daily net assets of the Fund and (ii) reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, taxes, interest, service fees, shareholder administration fees, brokerage fees, shareholder meeting, litigation, indemnification and extraordinary expenses) to 0.004% of the Fund's average daily net assets. These arrangements will remain in effect through at least July 29, 2016, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees. In addition, Goldman, Sachs & Co. ("Goldman Sachs") has agreed to waive a portion of the distribution and/or service (12b-1) fees equal to 0.35% of the average daily net assets attributable to Class C Shares of the Fund. Each arrangement will remain in effect through at least July 29, 2016, and prior to such date Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] Return for the Index is calculated from September 1, 1997, the commencement of the month nearest to the Class C Shares inception date.

[6] Return for the Index is calculated from October 1, 1994, the commencement of the month nearest to the Service Shares inception date.
