Schedule B (Form 1116): Foreign Tax Carryover Reconciliation Schedule
Schedule B (Form 1116), Foreign Tax Carryover Reconciliation Schedule, is a two-page schedule that the form says to attach to Form 1116. It tracks foreign tax carryover amounts by year, from the 10th preceding tax year through the current tax year, and ends with the foreign tax carryover to the following tax year on line 8.
The form says to use a separate Schedule B (Form 1116) for each applicable category of income and to check only one box on each schedule, the same separate category code shown on the Form 1116 it is attached to. The column (xiv) total on line 3 is included on the current year Form 1116, Part III, line 10.
The schedule does not print its instructions. It says "See separate instructions" and points to www.irs.gov/Form1116. You can fill it out free in your browser on this page and download the result without an account.
