Objective [Heading] rr_ObjectiveHeading Investment Objective
Objective, Primary [Text Block] rr_ObjectivePrimaryTextBlock The Goldman Sachs Structured Tax-Managed Equity Fund (the “Fund”) seeks to provide long-term after-tax growth of capital through tax-sensitive participation in a broadly diversified portfolio of U.S. equity securities.
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 $50,000 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 63 of this Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-81 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, including brokerage commissions, 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 December 31, 2011 was 99% of the average value of its portfolio.
Portfolio Turnover, Rate rr_PortfolioTurnoverRate 99.00%
Expenses Deferred Charges [Text Block] rr_ExpensesDeferredChargesTextBlock A contingent deferred sales charge (“CDSC”) is imposed on Class B Shares redeemed within six years of purchase, declining from a rate of 5% in the first year to 1% in the sixth year, and eliminated thereafter. A CDSC of 1% 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 $50,000 in Goldman Sachs Funds.

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 B, 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 B, 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:

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 equity investments in U.S. issuers, including foreign issuers that are traded in the United States. The Fund uses both a variety of quantitative techniques and fundamental research when selecting investments which have the potential to maximize the Fund’s after-tax return, and minimize capital gains and income distributions. The Fund will seek to maintain risk, style, capitalization and industry characteristics similar to the Russell 3000® Index.

In managing the Fund, the Investment Adviser balances investment considerations and tax considerations. The Fund seeks to achieve returns primarily in the form of price appreciation (which is not subject to current tax), and may use different strategies in seeking tax-efficiency. These strategies include:

  • Offsetting long-term and short-term capital gains with long-term and short-term capital losses and creating loss carry-forward positions
  • Limiting portfolio turnover that may result in taxable gains
  • Selling tax lots of securities that have a higher tax basis before selling tax lots of securities that have a lower tax basis

The Fund’s investments in fixed income securities are limited to cash equivalents.
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.

Foreign Risk. Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. Loss may also result from, among others, a slow U.S. economy, regional and global conflicts, the imposition of exchange controls, confiscations and other government restrictions, or from problems in registration, settlement or custody. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

Investment Style Risk. Different investment styles (e.g., “growth,” “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund employs a “quantitative” style, and may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Management Risk. A strategy used by the Investment Adviser may fail to produce the intended results. The Investment Adviser attempts to execute a complex strategy for the Fund using proprietary quantitative models. Investments selected using these models may perform differently than expected as a result of the factors used in the models, the weight placed on each factor, changes from the factors’ historical trends, and technical issues in the construction and implementation of the models (including, for example, data problems and/or software issues). There is no guarantee that the Investment Adviser’s use of these quantitative models will result in effective investment decisions for the Fund. Additionally, commonality of holdings across quantitative money managers may amplify losses.

Market Risk. The value of the instruments in which the Fund invests may go up or down in response to the prospects of individual companies, particular industry sectors or governments and/or general economic conditions.

Stock Risk. Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Tax-Managed Investment Risk. Because the Investment Adviser balances investment considerations and tax considerations, the pre-tax performance of the Fund may be lower than the performance of similar funds that are not tax-managed. Even though tax-managed strategies are being used, they may not reduce the amount of taxable income and capital gains distributed by the Fund to shareholders. A high percentage of the Fund’s NAV may consist of unrealized capital gains, which represent a potential future tax liability to shareholders. The Fund is not suitable for investment by IRAs, other tax-exempt or tax-deferred accounts or for other investors who are not sensitive to the federal income tax consequences of their investments.
Risk Lose Money [Text] rr_RiskLoseMoney Loss of money is a risk of investing in the Fund.
Risk Not Insured Depository Institution [Text] rr_RiskNotInsuredDepositoryInstitution 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.

[2] The Investment Adviser has agreed to (i) waive a portion of the management fee on the Fund equal to 0.05% of the Fund's average daily net assets, and (ii) reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, service and shareholder administration fees, transfer agency fees and expenses, taxes, interest, brokerage fees, litigation, indemnification, shareholder meeting and other extraordinary expenses) to 0.004% of the Fund's average daily net assets. These arrangements will remain in effect through at least April 27, 2013, and prior to such date the Investment Adviser may not terminate the arrangements without the approval of the Board of Trustees. The expense limitations may be modified or terminated by the Investment Adviser at its discretion and without shareholder approval after such date, although the Investment Adviser does not presently intend to do so. The Fund's "Other Expenses" may be further reduced by any custody and transfer agency fee credits received by the Fund.
