How to File Final Income Taxes as Executor in Tennessee

As an executor in Tennessee, you are responsible for filing the deceased person's final federal and state income tax returns. This obligation applies regardless of whether the estate is large or small, and missing deadlines can result in penalties that reduce the inheritance left to beneficiaries.

What Exactly Is the Final Income Tax Return?

The final income tax return covers the period from January 1 through the date of death in the year the person passed away. If someone died on June 15, 2024, for example, you file a return covering January 1 to June 15, 2024. This is separate from any estate income tax return (Form 1041) you may also need to file for income earned by the estate after the date of death.

Federal returns use IRS Form 1040, marked as "Deceased" with the date of death noted. Tennessee does not levy a state personal income tax on wages and salaries, which simplifies the process somewhat. However, if the decedent had interest and dividend income exceeding $1,250 (for single filers) or $2,500 (for joint filers), Tennessee's Hall Income Tax phased out but still applicable for certain tax years may require a separate state filing.

When Does This Apply to Your Situation?

You must file a final return if the decedent met the federal filing threshold for the partial year of death. Filing is also necessary if the decedent had taxes withheld from any income source and wants to claim a refund. Even if the decedent earned minimal income, filing can prevent future IRS inquiries into the estate.

Adjust your approach based on the complexity of the estate. A simple estate with one W-2 and standard deductions requires far less preparation than an estate with rental properties, business income, or multiple retirement accounts. Review the decedent's prior year returns first they reveal patterns in income sources, deductions, and filing choices that guide your current-year filing.

Step-by-Step: Filing the Final Return in Tennessee

  1. Obtain your authority documentation. Gather the Letters Testamentary issued by the Tennessee probate court. You will need these to act on behalf of the decedent with the IRS and financial institutions.
  2. Apply for an EIN if needed. If the estate earns income after the date of death, request an Employer Identification Number from the IRS using Form SS-4.
  3. Collect all income documents. Request W-2s, 1099s, and 1099-Rs from employers, banks, and brokerage firms. Institutions may send these to "Estate of [Name]" once notified of the death.
  4. Identify applicable deductions and credits. Medical expenses paid within one year of death can be deducted on the final return, even if unpaid at the time of death. Charitable contributions made before death also qualify.
  5. File Form 1040 with the appropriate status. Use the filing status the decedent was entitled to as of December 31 typically Single, Married Filing Jointly, or Qualifying Surviving Spouse. Write "DECEASED" and the date of death across the top.
  6. Sign as executor. Sign the return with your name and title: "John Smith, Executor of the Estate of Jane Smith, Deceased."
  7. File by the standard deadline. The return is due on April 15 of the year following the year of death, unless you request an extension using Form 4868.

Common Mistakes Executors Make

  • Mixing personal and estate funds. Keep all financial transactions separate to avoid liability issues.
  • Forgetting to notify the IRS. File Form 56 to formally notify the IRS that you are acting as the estate's representative.
  • Ignoring the estate tax return. If the estate exceeds the federal exemption threshold, Form 706 is due nine months after death.
  • Missing Tennessee-specific obligations. While Tennessee has no inheritance tax for deaths occurring after January 1, 2016, the estate tax filing threshold may still apply for larger estates.
