Form Overview

IRS Form 8991 - 8991

Form 8991 is the Tax on Base Erosion Payments (BEAT) used by large corporations that make deductible payments to foreign affiliates. File it with the corporation’s income tax return for the year the payments were made.

It captures total deductible payments to foreign related parties, the BEAT rate, the calculated BEAT tax, and any credit or reduction applied.

Risk Radar

Scan points

  • 2Using the wrong BEAT rate for the tax year

  • 4Misclassifying a payment as non‑deductible
  • 5Incorrectly applying the BEAT credit

Plain English

If your U.S. company pays a lot of interest, royalties, or other deductible fees to foreign related parties, the IRS may tax those payments under BEAT. This form calculates that extra tax and is attached to the regular corporate tax return.
