IRS Instruction 1120-L – IRS Forms, Instructions, Pubs 2026 – In the complex world of corporate taxation, life insurance companies face unique requirements when filing their annual returns. IRS Form 1120-L, the U.S. Life Insurance Company Income Tax Return, is essential for reporting income, deductions, credits, and tax liabilities. This SEO-optimized guide breaks down the 2025 instructions for Form 1120-L, helping tax professionals, company executives, and compliance officers navigate the process efficiently. We’ll cover everything from who must file to key updates, ensuring you stay compliant with the latest IRS guidelines.
What is IRS Form 1120-L?
Form 1120-L is specifically designed for life insurance companies to report their income, gains, losses, deductions, and credits, while calculating their income tax liability. Unlike the standard Form 1120 used by general corporations, this form accounts for the specialized financial structures of life insurers, including reserves, policyholder dividends, and investment income. It incorporates life insurance company taxable income (LICTI) under sections like 807 and 816 of the Internal Revenue Code.
Key elements include:
- Income Reporting: Gross premiums, investment income, and capital gains.
- Deductions: Reserves for future policy benefits, death benefits, and policy acquisition expenses.
- Taxes and Credits: Computation of income tax at 21%, plus potential alternative minimum tax (CAMT) and credits like foreign tax credits.
This form ensures accurate taxation for entities primarily engaged in issuing life insurance or annuity contracts that meet the reserves test.
Who Must File Form 1120-L?
Every domestic life insurance company must file Form 1120-L, including organizations under section 501(m)(1) that provide commercial-type life insurance. Foreign corporations that qualify as life insurance companies if they were U.S.-based also fall under this requirement. Additionally:
- Mutual savings banks with life insurance operations under section 594 file a partial tax using this form.
- Foreign life insurers disposing of U.S. real property interests attach Schedule D.
If your entity issues insurance or annuity contracts and reinsures risks, with a focus on life-related products meeting section 816 reserves tests, filing is mandatory. Consolidated returns may apply for affiliated groups, but the tax year is generally the calendar year unless otherwise specified.
Filing Deadlines and Extensions for 2025
For the 2025 tax year, the return is due by the 15th day of the fourth month following the end of the tax year—typically April 15, 2026, for calendar-year filers. Electronic filing is encouraged and often required for larger entities.
To request an extension, use Form 7004, which provides an automatic six-month extension. However, this extends only the filing deadline, not the payment due date—estimated taxes must still be paid on time to avoid penalties. File at the IRS Ogden Service Center, with addresses varying by location and whether a payment is enclosed.
