What Is IRS Form 1120-L?

IRS Form 1120-L, the U.S. Life Insurance Company Income Tax Return, is the mandatory federal tax form for domestic life insurance companies and qualifying foreign entities under IRC Section 801. It computes taxable income using unique methodologies like the reserves test (Section 816(a)), segregating life insurance gross income from other operations, and applies a 21% corporate tax rate on non-life activities while deferring taxes on certain policyholder reserves.

Key components include:

Life/Non-Life Segregation: Reports life insurance company taxable income (LICTI) on Page 1 and policyholder surplus adjustments.
Schedules: A (taxable income), F (policy acquisition expenses), M-1 (reconciliation), and more.
Attachments: NAIC annual statement and, for assets ≥ $10M, Schedule M-3 for net income reconciliation.

For 2025, filers must integrate digital asset questions and QOF investment reporting via Form 8997. This form isn’t just compliance—it’s a tool for claiming credits like the general business credit (Form 3800) and optimizing deductions under Section 807.

Who Must File IRS Form 1120-L in 2025?

Every domestic life insurance company—defined as one where life reserves + unearned premiums/unpaid losses on noncancellable policies exceed 50% of total reserves—must file Form 1120-L, regardless of income level. This includes Section 501(m)(1) organizations offering commercial-type insurance.

Eligible Entities

Entity Type	Filing Obligation	Key Notes
Domestic Life Insurers	Required	Includes annuity and combined life/health providers; attach NAIC statement.
Foreign Life Insurers	Required if U.S.-engaged	File if selling U.S. real property (Section 897); report effectively connected income.

Small Insurers (Assets < $10M)	Required, but Schedule M-3 optional	Voluntary M-3 filing recommended for transparency.
Terminated Companies	Final return marked	Attach Form 966 if dissolved.

Exclusions: Property/casualty insurers file Form 1120-PC; non-insurance corps use Form 1120.

E-filing is mandatory for companies filing 10+ returns annually via the Modernized e-File system. Foreign filers without U.S. business may qualify for streamlined reporting.

Recent Changes to IRS Form 1120-L for Tax Year 2025

The IRS’s 2024 instructions (Rev. Feb 2025) apply to 2025 returns, with no major structural overhauls but targeted enhancements for compliance and inflation adjustments:

Escalated Late-Filing Penalty: Minimum penalty for returns >60 days late rises to the smaller of tax due or $510 (from $485 in 2024), per IRS Notice adjustments.
Updated Dividends-Received Deduction Worksheet: Schedule A, Lines 10/21 now incorporate Section 250 GILTI/REIT dividends impacts, aiding international exposure.
Digital Assets & QOF Reporting: New checkboxes for digital asset transactions; attach Form 8997 for qualified opportunity fund investments held anytime in 2025.
Schedule M-3 Enhancements: For assets ≥ $10M, expanded mixed-group rules require subgroup consolidations (1120-L vs. 1120-PC); voluntary filers must check Item A, Box 3.
NAIC Integration: Electronic filers no longer attach full NAIC statements but must reference them; paper filers still include copies.
Interest Expense Limitations: Form 8990 required for Section 163(j) calculations, with no changes to thresholds.

These align with broader IRS modernization, including post-release tweaks in March 2025 for e-file validations.
