Before you invest, you may want to review the Fund's statutory prospectus ("Prospectus"), which contains more information about the Fund and its risks. You can find the Fund's Prospectus and other information about the Fund, including the Statement of Additional Information ("SAI") and the most recent Annual and Semi-Annual Reports to Shareholders ("Shareholder Reports"), online at www.morganstanley.com/im/MSIFTUltraShortIncome. You can also get this information at no cost by calling toll-free 1-866-414-6349 or by sending an e-mail request to orders@mysummaryprospectus.com. The Fund's Prospectus and SAI, both dated January 27, 2023 (as may be supplemented from time to time), are incorporated by reference into this Summary Prospectus.

**Investment Objective**

The Ultra-Short Income Portfolio (the "Fund") seeks current income with capital preservation while maintaining liquidity.

**Fees and Expenses**

The table below describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. **You may pay fees** **other than the fees and expenses of the Fund, such as brokerage commissions and other fees charged by financial** **intermediaries, which are not reflected in the tables and examples below. The Fund does not charge any sales loads or other** **fees when you purchase or redeem shares.**

**Annual Fund Operating Expenses** (expenses that you pay each year as a percentage of the value of your investment)

**Example**

The example below 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 the Fund, 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/or expense reimbursement arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

**Portfolio Turnover**

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Total Annual Fund Operating Expenses or in the Example, affect the Fund's performance. During the reporting period, the Fund did not hold any long-term investments and accordingly portfolio turnover is not applicable.

**Principal Investment Strategies**

The Fund invests primarily in liquid, high quality U.S. dollar-denominated money market instruments of U.S. and foreign financial issuers and non-financial issuers. The Fund also invests in obligations issued or guaranteed by the U.S. Government and its agencies and instrumentalities. The Fund's money market investments may include commercial paper, corporate debt obligations, debt obligations (including certificates of deposit and promissory notes) of U.S. banks or foreign banks, or of U.S. branches or subsidiaries of foreign banks, or foreign branches of U.S. banks (such as Yankee obligations), certificates of deposit of savings banks and savings and loan organizations, asset-backed securities, repurchase agreements and municipal obligations.

Pursuant to a fundamental policy adopted by the Fund, the Fund invests, under normal circumstances, at least 25% of its total assets in securities issued by companies in the financial services industry, including banks, broker-dealers and insurance companies.

Securities purchased by the Fund (or the issuers of such securities) will carry a rating in the highest two rating categories, A-2, P-2 or F2 or better by S&P Global Ratings Group, a division of S&P Global Inc. ("S&P"), Moody's Investors Service, Inc. ("Moody's"), or Fitch Ratings, Inc. ("Fitch"), respectively, or the equivalent by another nationally recognized statistical rating organization ("NRSRO"), or if unrated, considered by the Adviser to be of equivalent quality. The Fund may invest up to 5% of its assets, determined at the time of investment, in securities (or the issuers of such securities) rated A-2, P-2 or F2 by S&P, Moody's or Fitch, respectively, and no more than 1% of its assets will be invested in an individual security or issuer with such rating. In the case of a security that is rated differently by these three rating agencies, where two rating agencies rate the security in the highest rating category and the third rating agency rates the security in the second highest rating category, the security will be treated as rated in the highest rating category. In the case of a security that is differently rated by only two of these rating agencies, the security will be treated as rated in the lower rating category.

Under normal circumstances, the Fund intends to maintain a maximum weighted average maturity of 90 days and a maximum weighted average life of 180 days.

The Fund is not a money market fund and does not seek to maintain a stable net asset value per share ("NAV").

The Adviser follows a multi-pronged investment process with respect to credit risk, interest rate risk and liquidity. Securities are reviewed on an ongoing basis to maintain or improve creditworthiness taking into consideration factors such as cash flow, asset quality, debt service coverage ratios and economic developments. Additionally, exposure to guarantors and liquidity providers is monitored separately as are the various diversification requirements. The Adviser manages the Fund's assets in an attempt to reduce credit and interest rate risks.

**Principal Risks**

There is no assurance that the Fund will achieve its investment objective, and you can lose money investing in this Fund. The principal risks of investing in the Fund include:

• **Fixed-Income Securities.** Fixed-income securities are subject to the risk of the issuer's inability to meet principal and interest payments on its obligations (i.e., credit risk) and are subject to price volatility resulting from, among other things, interest rate sensitivity (i.e., interest rate risk), market perception of the creditworthiness of the issuer and general market liquidity (i.e., market risk). For example, a type of fixed-income securities in which the Fund may invest are corporate debt obligations. In addition to interest rate, credit and other risks, corporate debt obligations are also subject to factors directly related to the issuer, such as the credit rating of the corporation, the corporation's performance and perceptions of the corporation in the marketplace, and by factors not directly related to the issuer, such as general market liquidity, economic conditions and inflation. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates.  The Fund may be subject to certain liquidity risks that may result from the lack of an active market and the reduced number and capacity of traditional market participants to make a market in fixed-income securities.

• **Financial Services.** The Fund is more susceptible to any economic, business, political, regulatory or other developments that adversely affect issuers in the financial services industry than a fund that does not invest significantly in the financial services industry. The profitability of many types of financial services companies may be adversely affected in certain market cycles, including periods of rising interest rates, which may restrict the availability and increase the cost of capital, and declining economic conditions, which may cause credit losses due to financial difficulties of borrowers. Financial services companies are also subject to extensive government regulation, including policy and legislative changes in the United States and other countries that are changing many aspects of financial regulation.

• **Credit and Interest Rate Risk.** Credit risk refers to the possibility that the issuer or guarantor of a security will be unable or unwilling or perceived to be unable or unwilling to make interest payments and/or repay the principal on its debt. In such instances, the value of the Fund could decline and the Fund could lose money. Interest rate risk refers to the decline in the value of a fixed-income security resulting from changes in the general level of interest rates. When the general level of interest rates goes up, the prices of most fixed-income securities go down. When the general level of interest rates goes down, the prices of most fixed-income securities go up. The Fund may invest in variable and floating rate loans and other variable and floating rate securities. Although these instruments are generally less sensitive to interest rate changes than fixed rate instruments, the value of variable and floating rate loans and other securities may decline if their interest rates do not rise as quickly, or as much, as general interest rates. The Fund may face a heightened level of interest rate risk in times of monetary policy change and/or uncertainty, such as when the Federal Reserve Board adjusts a quantitative easing program and/or changes rates. A changing interest rate environment increases certain risks, including the potential for periods of volatility, increased redemptions, shortened durations (i.e., prepayment risk) and extended durations (i.e., extension risk). During periods when interest rates are low or there are negative interest rates, the Fund's yield (and total return) also may be low or otherwise adversely affected or the Fund may be unable to maintain positive returns. Credit ratings may not be an accurate assessment of liquidity or credit risk. Although credit quality may not accurately reflect the true credit risk of an instrument, a change in the credit rating of an instrument or an issuer can have a rapid, adverse effect on the instrument's liquidity and make it more difficult for the Fund to sell at an advantageous price or time.

• **U.S. Government Securities.** Different types of U.S. government securities are subject to different levels of credit risk, including the risk of default, depending on the nature of the particular government support for that security. For example, a U.S. government- sponsored entity, such as Federal National Mortgage Association or Federal Home Loan Mortgage Corporation, although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and, therefore, are not backed by the full faith and credit of the United States. With respect to U.S. government securities that are not backed by the full faith and credit of the United States, there is the risk that the U.S. Government will not provide financial support to such U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law.

• **Asset-Backed Securities.** Asset-backed securities are subject to credit (such as a borrower's default on its mortgage obligation and the default or failure of a guarantee underlying the asset-backed security), interest rate and certain additional risks, including the risk that various federal and state consumer laws and other legal and economic factors may result in the collateral backing the securities being insufficient to support payment on the securities. Some asset-backed securities also entail prepayment risk and extension risk, which may vary depending on the type of asset. Due to these risks, asset-backed securities may become more volatile in certain interest rate environments.

• **Repurchase Agreements.** Repurchase agreements are subject to risks associated with the possibility of default by the seller at a time when the collateral has declined in value, or insolvency of the seller, which may affect the Fund's right to control the collateral and result in certain costs and delays. Repurchase agreements may involve a greater degree of credit risk than investments in U.S. government securities.

• **Foreign Money Market Securities.** Investing in money market securities of foreign issuers involves some additional risks, including the possibility of adverse political, economic or other developments affecting the issuers of these securities.

• **Foreign Securities.** The Fund may invest in U.S. dollar-denominated securities issued by foreign governmental or corporate issuers. Investing in securities of foreign issuers involves some additional risks than securities of U.S. issuers. While these securities are subject to the same type of risks that pertain to domestic issuers, namely credit risk and interest rate risk, they are also subject to other additional risks. Foreign issuers generally are subject to different accounting, auditing and financial reporting standards than

U.S. issuers. There may be less information available to the public about foreign issuers. In some foreign countries, there is also the risk of government expropriation, excessive taxation, political or social instability, economic sanctions or other similar governmental activity or diplomatic developments that could affect an investment. There also can be difficulty obtaining and enforcing judgments against issuers in foreign countries. Governmental actions can have a significant effect on the economic conditions in foreign countries, which also may adversely affect the Fund's investments in foreign issuers.

• **Municipals.** Because the Fund may invest in municipal securities (also referred to as municipal obligations), the Fund may be susceptible to political, legislative, economic, regulatory, tax or other factors affecting issuers of these municipal securities, such as state and local governments and their agencies. To the extent that the Fund invests in municipal securities of issuers in the same economic sector, it could be more sensitive to economic, business or political developments that affect such sector. Municipal securities and their issuers may be more susceptible to downgrade, loss of revenue, default and bankruptcy because of recent periods of economic stress. Municipal securities also involve the risk that an issuer may call the securities for redemption, which could force the Fund to reinvest the proceeds at a lower rate of interest.

• **Liquidity.** The Fund may make investments that are illiquid or restricted or that may become illiquid or less liquid in response to overall economic conditions or adverse investor perceptions, and which may entail greater risk than investments in other types of securities. These investments may be more difficult to value or sell, particularly in times of market turmoil, and there may be little trading in the secondary market available for particular securities. Liquidity risk may be magnified in a market where credit spread and interest rate volatility is rising and where investor redemptions from fixed-income mutual funds may be higher than normal. If the Fund is forced to sell an illiquid or restricted security to fund redemptions or for other cash needs, it may be forced to sell the security at a loss or for less than its fair value.

• **LIBOR Discontinuance or Unavailability Risk.** The London InterBank Offered Rate ("LIBOR") is intended to represent the rate at which contributing banks may obtain short-term borrowings from each other in the London interbank market. The Financial Conduct Authority (the "FCA"), which is the regulatory authority that oversees financial services firms, financial markets in the U.K. and the administrator of LIBOR, announced that, after the end of 2021, one-week and two-month U.S. Dollar LIBOR and all non-U.S. Dollar LIBOR settings have either ended or are no longer representative of the underlying market they seek to measure. The FCA also announced that the most commonly used U.S. dollar LIBOR settings  may continue to be provided on a representative basis until mid-2023. However, in connection with supervisory guidance from regulators, some regulated entities may no longer enter into most new LIBOR-based contracts. As a result of the foregoing, LIBOR may no longer be available or no longer deemed an appropriate reference rate upon which to determine the interest rate on or impacting certain loans, notes, derivatives and other instruments or investments held by the Fund.

• **Commercial Paper.** Commercial paper is subject to interest rate risk and is susceptible to changes in the issuer's financial condition or credit quality. Commercial paper is typically repaid with the proceeds from the issuance of new commercial paper. Thus, investments in commercial paper are subject to the risk (commonly referred to as rollover risk) that the issuer will be unable to issue sufficient new commercial paper to meet the repayment obligations under its outstanding commercial paper. Because commercial paper is typically unsecured, investments in commercial paper are subject to increased credit risk.

• **Market and Geopolitical Risk.** The value of your investment in the Fund is based on the values of the Fund's investments, which may change due to economic and other events that affect markets generally, as well as those that affect particular regions, countries, industries, companies or governments. These events may be sudden and unexpected, and could adversely affect the liquidity of the Fund's investments, which may in turn impact valuation, the Fund's ability to sell securities and/or its ability to meet redemptions. The risks associated with these developments may be magnified if certain social, political, economic and other conditions and events (such as war, natural disasters, epidemics and pandemics, terrorism, conflicts, social unrest, recessions, inflation, rapid interest rate changes and supply chain disruptions) adversely interrupt the global economy and financial markets. It is difficult to predict when events affecting the U.S. or global financial markets may occur, the effects that such events may have and the duration of those effects (which may last for extended periods). These events may negatively impact broad segments of businesses and populations and have a significant and rapid negative impact on the performance of the Fund's investments , adversely affect and increase the volatility of the Fund's share price and exacerbate pre-existing risks to the Fund.

• **Active Management Risk.** In pursuing the Fund's investment objective, the Adviser has considerable leeway in deciding which investments to buy, hold or sell on a day-to-day basis, and which trading strategies to use. For example, the Adviser, in its discretion, may determine to use some permitted trading strategies while not using others. The success or failure of such decisions will affect the Fund's performance.

Shares of the Fund are not bank deposits and are not guaranteed or insured by the Federal Deposit Insurance Corporation or any other government agency.

**Performance Information**

The bar chart and table below provide some indication of the risks of investing in the Fund by showing changes in the Fund's Institutional Class shares' performance from year-to-year and by showing how the Fund's average annual returns for the past one and five year periods and since inception compare with those of a broad measure of market performance, as well as an index that represents a group of similar mutual funds, over time. The performance of the other classes, which is shown in the table below, will differ because the classes have different ongoing fees. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available online at www.morganstanley.com/im or by calling toll-free 1-800-869-6397.
