IRS Form 2439, titled Notice to Shareholder of Undistributed Long-Term Capital Gains, is a tax form used by Regulated Investment Companies (RICs) and Real Estate Investment Trusts (REITs) to report undistributed long-term capital gains to their shareholders. When a RIC or REIT pays tax on capital gains that it has not distributed to shareholders, it must notify those shareholders using Form 2439. This form details the amount of undistributed capital gains allocated to each shareholder, including special categories like unrecaptured section 1250 gain, section 1202 gain, and collectibles gain taxed at a 28% rate. The form also reports the tax paid by the RIC or REIT on those gains, which shareholders may be eligible to credit or claim as a refund on their individual tax returns. Form 2439 serves as an important document for shareholders to correctly report these gains on their income tax returns, typically on Schedule D or Form 8949, depending on their taxpayer status. The form is issued annually and includes multiple copies for filing with the IRS, providing to shareholders, and retaining for records. Understanding and accurately completing Form 2439 is crucial for RICs, REITs, and shareholders to ensure proper tax reporting and compliance with IRS regulations.
