1. Introduction – What is Schedule Q (Form 1066)?
Schedule Q (Form 1066), officially titled “Quarterly Notice to Residual Interest Holder of REMIC Taxable Income or Net Loss Amount,” is a specialized federal tax statement administered by the Internal Revenue Service (IRS), an agency of the U.S. Department of the Treasury.
It is authorized under Internal Revenue Code (IRC) Sections 860E and 860G. Prepared and issued quarterly by Real Estate Mortgage Investment Conduits (REMICs), Schedule Q informs holders of “residual interests” of their pro-rata share of quarterly REMIC taxable income, net losses, excess inclusion amounts, and allocable investment expenses.
2. Purpose of the Form – Why Does Schedule Q (Form 1066) Exist?
A Real Estate Mortgage Investment Conduit (REMIC) holds a fixed pool of mortgages and issues two types of investor securities: regular interests and residual interests. While regular interest holders receive fixed bond-like interest payments (reported on Form 1099-INT or Form 1099-OID), residual interest holders carry the equity profits or net operational losses of the mortgage pool.
Because a REMIC is a pass-through entity that pays no direct corporate income tax, its net earnings pass through directly to residual interest holders on a quarterly basis.
Schedule Q (Form 1066) serves as the official quarterly tax reporting statement. It translates complex mortgage pool accounting into specific tax figures—such as quarterly taxable income, net losses, allocated Section 212 management expenses, and “excess inclusions”—allowing residual investors to report income accurately on their annual personal or corporate tax returns.
3. Who Needs to File / Receive This Form
Schedule Q involves two distinct parties: the REMIC trustee who prepares and issues it, and the residual investor who receives it:
- REMIC Trustees & Administrators (Issuers): Must complete and issue Schedule Q every quarter to each holder of a residual interest in the REMIC.
- Residual Interest Holders (Recipients): Individual investors, corporations, partnerships, or tax-exempt entities holding residual REMIC securities who must use Schedule Q to report quarterly income or loss on their annual tax returns (such as Form 1040, Form 1120, or Form 990-T).
4. Who Is Exempt / Not Required to File
You do not need to issue or receive Schedule Q (Form 1066) if your investment or entity situation falls into any of these categories:
- Regular Interest Holders: Investors holding “regular interests” in a REMIC (who receive standard Form 1099-INT or Form 1099-OID interest statements instead).
- Non-REMIC Mortgage Entities: Real Estate Investment Trusts (REITs) or mortgage companies that did not elect REMIC status under IRC Section 860D.
- General Retail Investors: Individual investors with no residual equity holdings in mortgage-backed securitization pools.
5. When to File
Unlike most IRS schedules that are prepared annually, Schedule Q (Form 1066) is generated and distributed **four times a year** following each calendar quarter.
REMIC trustees must furnish Copy B of Schedule Q to each residual interest holder by the **last day of the month following the close of the calendar quarter**:
| Calendar Quarter | Quarter Coverage Period | Schedule Q Due Date to Investors |
|---|---|---|
| Quarter 1 | January 1 – March 31 | April 30 |
| Quarter 2 | April 1 – June 30 | July 31 |
| Quarter 3 | July 1 – September 30 | October 31 |
| Quarter 4 | October 1 – December 31 | January 31 (Following Year) |
In addition to quarterly investor delivery, the REMIC trustee must attach Copy A of all four quarterly Schedule Q forms to the REMIC’s annual Form 1066 return filed with the IRS on or before **April 15** (or **September 30** if an extension is filed on Form 7004).
6. Where and How to File
REMIC trustees deliver Copy B of Schedule Q directly to residual investors by postal mail or secure digital portal. Trustees file Copy A for all four calendar quarters attached directly behind annual Form 1066 sent to the IRS.
Electronic filing is recommended when submitting Form 1066 and Schedule Q to the IRS using approved software. Residual investors do **not** mail Schedule Q to the IRS with their personal tax returns; they keep Copy B for their records and enter the reported box figures onto Schedule E (Form 1040), Form 1120, or Form 990-T.
7. Step-by-Step Instructions to Fill the Form
Schedule Q consists of REMIC identification header details, investor ownership percentage lines, and specific income allocation boxes. The table below outlines the primary reporting boxes on the form.
| Box Number | Box Title | Tax Reporting Instruction for Investors |
|---|---|---|
| Box 1a | Taxable Income (or Net Loss) | Report on Schedule E (Form 1040), Part IV for individuals, or Form 1120 for corporations. |
| Box 1b | Excess Inclusion Amount | Reported on Schedule E. Represents income that CANNOT be offset by Net Operating Losses (NOLs). |
| Box 2a | Section 212 Investment Expenses | Reported as allocable investment management expenses for single-class pass-through REMICs. |
| Box 2b | Tax-Exempt Entity Warning | Discloses excess inclusions for tax-exempt investors, which are taxed as UBTI on Form 990-T. |
Detailed Filling Steps
- Complete REMIC & Investor Header: Enter the legal name, Employer Identification Number (EIN), and CUSIP number of the REMIC. Enter the residual interest holder’s legal name, Social Security Number (SSN) or EIN, address, and percentage of total residual interest held.
- Report Quarterly Taxable Income or Loss (Box 1a): Enter the residual holder’s pro-rata share of REMIC net taxable income or net loss for the 3-month calendar quarter.
- Calculate Excess Inclusion Amount (Box 1b): Under IRC Section 860E, compute the “excess inclusion” portion of Box 1a. (Excess inclusions represent income exceeding a hypothetical return on benchmark interest rates and receive special restrictive tax treatment).
- Report Section 212 Investment Expenses (Box 2a): For pass-through REMICs, enter the investor’s share of pool management fees, servicing costs, and trustee fees.
- Issue Copy B to Investors & File Copy A with IRS: Deliver Copy B to each residual investor by the quarterly deadline. Retain Copy A to attach behind annual Form 1066.
8. Required Documents/Information Needed Before Filling
To ensure an accurate Schedule Q (Form 1066) preparation, REMIC trustees must gather the following accounting records:
- REMIC EIN & CUSIP Registers: Official Employer Identification Number and CUSIP securities identification numbers for all residual classes.
- Residual Investor Roster: Legal names, street addresses, SSNs or EINs, and exact ownership percentages for all residual interest holders.
- Quarterly Mortgage Pool Financial Statements: Income statements showing mortgage interest collected, prepayment penalties, defaults, and pool servicing expenses for the quarter.
- Section 860E Excess Inclusion Worksheets: Mathematical calculations comparing quarterly REMIC income against 120% of federal long-term applicable rates to establish Box 1b figures.
9. Common Mistakes to Avoid
Errors on Schedule Q can cause immediate IRS audit flags and investor tax underpayment penalties. Watch out for these frequent mistakes:
- Missing Quarterly Investor Deadlines: Delaying delivery of Schedule Q past the last day of the month following the quarter’s end, preventing investors from estimating quarterly taxes.
- Miscalculating Excess Inclusions (Box 1b): Failing to calculate excess inclusions accurately. Excess inclusions cannot be offset by Net Operating Losses (NOLs) and trigger Unrelated Business Income Tax (UBIT) for tax-exempt holders!
- Issuing Schedule Q to Regular Interest Holders: Sending Schedule Q to regular interest holders instead of issuing standard Form 1099-INT or Form 1099-OID interest statements.
- Omitting Section 212 Investment Expenses: Failing to report allocable servicing fees in Box 2a for single-class pass-through REMICs.
- Mailing Copy A Separately to the IRS: Mailing paper Copy A forms to the IRS separately instead of attaching them behind annual Form 1066.
10. Penalties for Non-Filing or Errors
Failing to issue Schedule Q on time or reporting inaccurate numbers carries direct statutory penalties under federal tax law:
- Failure to Furnish Information Statements (IRC Section 6722): The IRS assesses fines ranging from **$60 to over $310 per missing or late Schedule Q notice** issued to residual interest holders (with higher penalties for intentional disregard).
- Investor Tax Audit Adjustments: Inaccurate Schedule Q numbers cause residual holders to misreport income on Schedule E or Form 1120, triggering partner/investor audit penalties and compound interest.
- Invalidation of REMIC Tax Status: Severe or persistent failure to issue required quarterly notices can jeopardize the pool’s tax-exempt REMIC election under IRC Section 860D.
