The Mississippi Fiduciary Income Tax Return is used to report Mississippi income, deductions, credits, payments, refunds, and any balance due for an estate or trust. A fiduciary, such as an executor, administrator, trustee, or authorized officer, completes the return for the entity rather than for an individual taxpayer. The return identifies the estate or trust, records the applicable entity type and filing status, calculates Mississippi taxable income through the Fiduciary Net Taxable Income Schedule, and determines whether the entity owes tax or has an overpayment. The return also provides fields for credits, withholding, estimated payments, pass-through entity tax credits, beneficiary allocation information, exemption amounts, and preparer authorization. Estates and trusts with Mississippi income or a Mississippi filing requirement use this return to report their tax position accurately and ensure that income allocated to beneficiaries, tax already paid, and any remaining tax obligation are properly reflected for the 2025 tax year.
How To File The Mississippi Fiduciary Income Tax Return
Complete both pages of the return before mailing it. Page 2 calculates taxable income for Mississippi purposes, and the final amount from page 2, line 26, is transferred to page 1, line 1. After completing the tax, payment, refund, or balance-due calculations on page 1, the fiduciary or authorized officer must sign and date the return. A paid preparer must also complete the preparer section when applicable.
Refund returns should be mailed to:

All other returns should be mailed to:
