How to File a Final Income Tax Return After a Death in Tennessee

Filing a final income tax return after a death in Tennessee is almost entirely a federal process. Tennessee has no state income tax on wages, and no Hall Income Tax on dividends or interest since 2021. You do not file a state income tax return for the deceased. What you do file is the federal Form 1040 with the IRS, covering the income the decedent earned from January 1 of the year of death through the date of death.

That distinction matters because it immediately reduces your workload. The final return for a Tennessee decedent is a standard federal Form 1040 — the same form the decedent filed every year — with some specific rules applied for the year of death. This guide walks through who must file it, what it covers, how to sign it, and what comes after.

Who Is Responsible for Filing the Final Return

The personal representative of the estate — the executor named in the will, or the administrator appointed by the probate court if there is no will — is responsible for filing the decedent's final income tax return.

If there is no appointed personal representative, the IRS allows a surviving spouse or other qualified person to file. A surviving spouse may file a joint return for the year of death if they were married to the decedent as of the date of death, even if the decedent died early in the year. This can significantly reduce the tax liability.

If the estate is going through probate, the executor has the legal authority to act on behalf of the decedent for tax purposes. File IRS Form 56 (Notice Concerning Fiduciary Relationship) to formally notify the IRS that you are acting as fiduciary. This is not required to file the return but is useful for ongoing IRS correspondence.

What the Final Form 1040 Covers

The final Form 1040 reports all income the decedent received from January 1 of the tax year through the date of death. It does not cover:

• Income earned after the date of death (that income belongs to the estate or the beneficiaries, not the decedent, and is handled on Form 1041 if above the threshold)
• Assets inherited by beneficiaries — inheriting property is not a taxable event on the final 1040

Income typically reported on the final 1040:

• Wages and salary through the date of death
• Social Security income received before death
• Retirement account distributions taken before death (IRA, 401(k), pension)
• Interest and dividend income earned through the date of death
• Business income through the date of death
• Capital gains on sales made before death

One important distinction for Tennessee executors: Because Tennessee has no state income tax, you are only filing federally. If the decedent had previously filed state returns in another state (e.g., if they relocated to Tennessee recently), you may still owe a final return in that state for the period of residence there.

The Tennessee State Tax Filing Question

For a decedent who was a Tennessee resident at the time of death and who died after 2020:

• No Tennessee state individual income tax return is required. Tennessee does not tax wages, salaries, or business income.
• No Tennessee Hall Income Tax return is required. The Hall Tax on dividends and interest was fully repealed effective January 1, 2021.
• No Tennessee inheritance tax return exists. The tax was repealed effective January 1, 2016.
• No Tennessee estate tax return exists. Tennessee has no state estate tax.
• No Tennessee gift tax return exists. The gift tax was repealed in 2012.

The one state-level tax that may apply: if the decedent owned a Tennessee business entity (LLC, corporation, limited partnership), a final franchise and excise tax return (Form FAE170) must be filed with the Tennessee Department of Revenue to obtain a tax clearance certificate and formally dissolve the entity. This is a business tax filing, not a personal income tax return.

Step-by-Step: Filing the Final Form 1040

Step 1: Gather income documentation

Collect all income statements for the full year of death:

• W-2 forms (wages paid through the date of death; some employers issue separate W-2s for wages paid after death, which go on the estate's return, not the final 1040)
• 1099 forms for interest, dividends, retirement distributions, Social Security
• Records of any business income, rental income, or capital gains transactions completed before death

Income received after the date of death — interest earned in a bank account after death, dividends on securities held in the decedent's name — is generally estate income and goes on Form 1041, not the final 1040.

Step 2: Determine filing status

The decedent's filing status on the final return is determined as of the date of death:

• If married and not legally separated, the surviving spouse may file a joint return for the full year of death. Joint filing is usually advantageous because it provides the full standard deduction and generally lower tax rates.
• If the surviving spouse remarries before the end of the tax year (unusual), they cannot file jointly with the deceased spouse.
• If unmarried, the decedent files as single (or head of household if they had qualifying dependents).

A surviving spouse who files jointly in the year of death may also qualify to file as a "qualifying surviving spouse" for the two subsequent tax years if they have a dependent child, which allows the use of married filing jointly rates.

Step 3: Apply the correct standard deduction

For 2026, the standard deductions are:

• Single filer: $16,100
• Married filing jointly: $32,200

The full standard deduction applies for the year of death — it is not prorated for the months the decedent was alive. This often surprises executors who assume the deduction is reduced for a partial year. It is not.

Step 4: Address medical expenses

Medical expenses paid for the decedent's final illness can be deducted either:

• On the final Form 1040 if paid before the end of the tax year, or
• On Form 706 (the federal estate tax return) if paid by the estate and the estate is large enough to require a 706 filing

The decision depends on where the deduction provides more benefit. Most estates below the federal threshold will not file Form 706, so deducting qualified medical expenses on the final 1040 (if they exceed 7.5% of adjusted gross income) is the more relevant option for most Tennessee estates.

Step 5: Handle income received after death that was already earned

Some income is earned before death but received after the date of death — for example, a final paycheck, the last dividend payment, or the last month's rent from a tenant. This type of income, called "income in respect of a decedent" (IRD), does not get a step-up in basis, and the taxation depends on who receives it and when.

If the personal representative receives the paycheck or payment, it is generally estate income and goes on Form 1041. The beneficiary who ultimately receives this money may get a deduction for the estate taxes attributable to IRD, which helps avoid full double taxation.

Step 6: Sign and annotate the return

The personal representative signs the return where the taxpayer would normally sign. Write "Filing as personal representative" or "Executor" next to the signature.

Annotate the decedent's name and date of death on the return. Write the word "DECEASED," the decedent's name, and the date of death across the top of Form 1040 on page 1.

If a refund is due and there is no surviving spouse filing jointly, file Form 1310 (Statement of Person Claiming Refund Due a Deceased Taxpayer) to claim the refund on behalf of the estate.

Step 7: File by the standard deadline

The final Form 1040 is due by April 15 of the year following the year of death. If additional time is needed, file Form 4868 for an automatic six-month extension (to October 15). Note that this extends the time to file, not the time to pay — if taxes are owed, interest accrues on any unpaid amount after April 15.

What Comes After the Final 1040

Filing the final Form 1040 resolves the decedent's personal income tax obligations. Two separate tax questions arise after that:

Form 1041 — Estate income tax

If the estate continues to hold assets that generate income (interest in an estate bank account, dividends from brokerage holdings, rental income from a house awaiting sale), and that income exceeds $600 in a tax year, the estate must file Form 1041. The estate's tax year begins on the date of death and can be either a calendar year or a fiscal year (the executor's choice).

Tennessee note: Because real property in Tennessee vests immediately in the heirs at the moment of death under T.C.A. § 31-2-103, the executor does not typically control the house through the estate the same way personal property is controlled. If heirs are receiving rental income from an inherited property, that income may belong to the heirs individually rather than the estate — in which case it is reported on the heirs' personal returns, not on Form 1041. This is a consequential distinction that generic federal resources do not address.

Form 706 — Federal estate tax

Required only if the gross estate exceeds $15,000,000 for deaths in 2026 (the threshold set by the One Big Beautiful Bill). Also filed voluntarily by executors who want to elect portability — transferring the deceased spouse's unused exclusion to the surviving spouse, which can shield up to $30,000,000 from federal estate taxes for married couples.

Common Mistakes Tennessee Executors Make

Trying to file a Tennessee state income tax return. Tennessee has no individual income tax on wages and no Hall Income Tax since 2021. Many executors, having seen references to Tennessee taxes online, spend time looking for a state return that does not exist.

Forgetting to obtain a step-up in basis documentation. The final 1040 does not require this, but it is a critical parallel task. Document the fair market value of all appreciated assets (brokerage accounts, real estate, business interests) on the date of death. This documentation is what beneficiaries need to claim the stepped-up basis when they eventually sell.

Treating post-death income as decedent income. Interest earned in a bank account after the date of death belongs to the estate (or to heirs under immediate vesting rules), not to the decedent. Reporting post-death income on the final 1040 creates an overpayment.

Missing the signature requirement. A return signed only by the surviving spouse as spouse — not as fiduciary — may not be accepted when the estate is the filer. Use the correct fiduciary language.

Distributing assets before tax liabilities are resolved. If the estate distributes assets to beneficiaries and then faces a tax liability, the executor can be held personally responsible for the difference. File the final 1040 and resolve any IRS response before making distributions from the estate.

Frequently Asked Questions

Does Tennessee require a state income tax return for a deceased person?

No. Tennessee has no state individual income tax on wages, and the Hall Income Tax on dividends and interest was fully repealed as of January 1, 2021. The only income-related state obligation that might apply is a final franchise and excise tax filing for business entities the decedent owned.

Can a surviving spouse file a joint return with a deceased spouse in Tennessee?

Yes. A surviving spouse may file a joint federal Form 1040 for the year of death, which is typically advantageous in terms of tax rates and standard deductions. There is no Tennessee state return to file jointly because Tennessee has no state income tax.

When is the final income tax return due after a death in Tennessee?

The final Form 1040 is due by April 15 of the year following the year of death — the same deadline as a living person's return. If the decedent died in 2025, the final return is due April 15, 2026. Extensions are available by filing Form 4868.

What happens if the deceased owed taxes on the final return?

Any taxes owed on the final Form 1040 are paid from estate funds. These are debts of the estate and must be paid before assets are distributed to beneficiaries. The executor is personally liable if they distribute assets without settling the tax debt.

Does inheriting money from a Tennessee estate create income tax liability for the beneficiaries?

Receiving an inheritance is not itself a taxable event for the beneficiary. There is no Tennessee inheritance tax and no federal inheritance tax. However, specific asset types do create future tax obligations: inheriting a traditional IRA means future withdrawals are taxed as ordinary income; inheriting appreciated stock or real estate means the beneficiary has a new stepped-up basis, but any appreciation after the date of death will be subject to capital gains tax when sold.

What is the difference between the final Form 1040 and Form 1041?

Form 1040 is the decedent's personal income tax return covering the period from January 1 of the year of death through the date of death. Form 1041 is the estate's income tax return covering income the estate earns after the date of death, before assets are distributed to beneficiaries. Both may need to be filed if the estate holds income-producing assets for any period of time.
