What Is Schedule I (Form 1041)?

Schedule I attaches to the Form 1041 – U.S. Income Tax Return for Estates and Trusts. It captures preference items, tax‑exempt interest, and other adjustments that affect the estate’s or trust’s AMT liability. The form is mandatory when the alternative minimum taxable income (AMTI) exceeds the threshold set by the IRS.
