U.S. shareholders of controlled foreign corporations who have GILTI or foreign oil and gas extraction income must attach Schedule I‑1 to their Form 5471 filing.

GILTI stands for Global Intangible Low‑Taxed Income. It is a category of income that U.S. shareholders must report to prevent tax deferral on foreign earnings.

Do I need to attach supporting documents to Schedule I-1?

Only if the IRS specifically requests additional detail for the items reported on lines 2a‑2e. Otherwise, the schedule itself is sufficient.

What if I make a mistake after filing?

Amend the original return by filing Form 1040X and attach a corrected Schedule I‑1. Include an explanation of the changes.

Is there a filing deadline for Schedule I-1?

Schedule I‑1 is due with the taxpayer’s Form 5471, which is attached to the individual’s annual tax return (typically April 15, with extensions as applicable).
