Whether you’re searching for “how to file IRS Form 1066” or “REMIC tax return instructions,” this article provides step-by-step insights to help you navigate the process efficiently.
What Is IRS Form 1066 and Its Purpose?
IRS Form 1066 is the official tax return for REMICs, used to report income, deductions, gains, and losses from REMIC operations. An entity files this form to document the financial activities of a REMIC, which is a special-purpose vehicle that holds a pool of mortgages and issues securities backed by those mortgages. Beyond standard reporting, Form 1066 is also used to calculate and pay taxes on specific items like net income from prohibited transactions, foreclosure property, and post-startup contributions.
REMICs must compute their taxable income using the accrual method of accounting under section 860C(b) of the Internal Revenue Code. This ensures that all financial activities are accurately reflected for tax purposes. If your entity has elected REMIC status and meets the requirements under section 860D(a), filing this form is mandatory.
Who Must File Form 1066?
Not every real estate entity needs to file Form 1066—it’s specifically for those that have elected REMIC treatment and maintain that status. Key criteria include:
- The entity must elect REMIC status for the tax year and all prior years.
- All interests must be classified as regular or residual.
- There can only be one class of residual interests, with distributions made pro rata.
- Assets must primarily consist of qualified mortgages and permitted investments (at least substantially all after the third month post-startup day).
- The REMIC must use a calendar tax year.
- Arrangements must be in place to prevent residual interests from being held by disqualified organizations.
Exceptions apply to REMICs with startup days before April 1, 1988, or those under binding contracts as of March 31, 1988. If your entity qualifies, file Form 1066 annually to stay compliant.
When and Where to File IRS Form 1066?
Timing is critical for REMIC tax returns. For the 2025 calendar year, file Form 1066 by March 15, 2026. If it’s a final return (e.g., the REMIC ceases operations), file by the 15th day of the third month after termination. Extensions can be requested using Form 7004, but they must be filed by the original due date.
For short tax years, adjust the filing deadline accordingly. If the 2026 form isn’t available yet, use the prior year’s version and clearly mark the tax year.
Where to File:
- U.S.-based principal businesses: Department of the Treasury, Internal Revenue Service, Ogden, UT 84201-0007.
- Foreign countries or U.S. territories: Internal Revenue Service, P.O. Box 409101, Ogden, UT 84409.
Use IRS-designated Private Delivery Services for timely postmarking. Electronic filing isn’t mentioned for this form, so paper filing is standard.
