IRS Publication 550 is an informational guide issued by the United States Internal Revenue Service (IRS) regarding taxation of investments. This comprehensive guide addresses items such as how to report dividend income and capital gains, as well as investment expenses, limits on losses, and exclusions from taxation.

The IRS first published IRS Publication 550 in 1960. The latest version of the publication was updated in 2020 to reflect the Tax Cuts and Jobs Act of 2017. The purpose of the publication is to inform taxpayers on the tax treatments of certain financial transactions in order to help them properly report their investment income and make the most of their investments.

In Publication 550, the IRS outlines the rules and regulations for tax reporting on several investment types, such as stocks and bonds, as well as mutual funds and annuities. It clarifies which investments are subject to taxes and which are not, including short-term and long-term capital gains and losses, as well as special rules related to the disposal of inherited stocks. The publication also details the wash sale rule and qualified dividends, sale of exchange funds, and more.

Another purpose of the IRS Publication 550 is to provide guidance on how to calculate and report basis when figuring capital gains and losses. Basis is the cost of an investment that is used in taxation, and can be determined by various methods including the “FIFO” (First In, First Out) and “LIFO” (Last In, First Out) methods.

IRS Publication 550 includes information on charitable donations of investments, such as the proper method for valuing stocks and bonds for tax-deductible donations.
