Schedule K-1-T (IL-1041) is a form used by estates and trusts in Illinois to report the share of income, deductions, and other financial information allocated to each beneficiary. This form is attached to Form IL-1041, which is the Illinois Income Tax Return for Estates and Trusts. It provides a detailed breakdown of the beneficiary’s share of both nonbusiness and business income or loss, including capital gains, dividends, interest, and rental income. Additionally, it accounts for Illinois-specific additions and subtractions such as state tax exemptions, special depreciation, and contributions to job training projects. Schedule K-1-T also includes information about any pass-through withholding, pass-through entity tax credits, and federal income subject to surcharge. Beneficiaries receiving this form should attach it to their Illinois tax returns to accurately report their share of the estate or trust’s income and deductions. It is a key document in the taxation process for trusts, estates, and their beneficiaries in Illinois.
How To File Schedule K-1-T (IL-1041)
