How to File the Final Tax Return for a Deceased Person in Texas Without a CPA

Filing the final income tax return for someone who died in Texas is one of the first tax obligations an executor or surviving spouse faces — and it is one you can handle without a CPA for most estates. Here is how it works: the decedent's final Form 1040 covers January 1 through the date of death, is filed by April 15 of the year after death (or October 15 with an extension), and requires the executor or surviving spouse to sign on behalf of the decedent. Texas adds one meaningful simplification — there is no state income tax return to file, because Texas levies no individual income tax.

This page walks through every step of the final Form 1040 for a Texas decedent: who files, which income to include, how community property changes the calculation, what to do if no executor has been appointed, and when to route specific situations to a CPA.

Why Texas Makes This Simpler Than Most States

Texas has no state individual income tax. This means one entire layer of the final tax return process disappears. You are filing one return — the federal Form 1040 — not a federal return plus a state return. Whatever the decedent earned in Texas wages, investment income, or business income, none of it generates a separate Texas return obligation. This is the one area where "Texas has no state tax" genuinely simplifies your workload.

Step 1: Confirm You Need to File

A final federal Form 1040 is required if the decedent would have met the standard filing threshold had they survived the entire year. For 2025, that threshold is $15,000 for single filers and $30,000 for married filing jointly (these are approximate standard deduction + personal exemption equivalents — the IRS adjusts these annually). If the decedent's income from January 1 through the date of death was below the threshold, no return is required. However, if federal taxes were withheld from wages or retirement distributions, filing a return is the only way to claim a refund of overwithheld amounts — so it almost always makes sense to file even for small estates.

Step 2: Establish Who Has Authority to File

The person who signs and files the final return depends on the decedent's marital status and whether an executor has been formally appointed:

Surviving spouse: If the decedent was married, the surviving spouse can file jointly for the year of death as if the marriage existed for the entire year. This is almost always the most tax-efficient choice — it preserves the higher standard deduction and lower bracket thresholds. The surviving spouse signs the return and writes "Filing as Surviving Spouse" next to their signature.

Court-appointed executor or administrator: If an executor has received Letters Testamentary from the Texas probate court, the executor signs the return. The executor writes "Personal Representative" next to the signature and may need to attach IRS Form 56 (Notice Concerning Fiduciary Relationship) to notify the IRS of the fiduciary relationship.

No executor appointed: If there is no surviving spouse and no court-appointed executor, any person who is responsible for the decedent's property may file the return. Write "deceased" after the decedent's name and enter the date of death. The IRS will accept this, but the filer cannot claim a refund without Form 1310 (Statement of Person Claiming Refund Due a Deceased Taxpayer).

IRS Form 1310: This form is required in any refund situation where the person claiming the refund is not the surviving spouse filing jointly and is not a court-appointed executor. File it with the return to unlock the refund.

Step 3: Determine Which Income to Include

The final Form 1040 covers income the decedent actually received (or was legally entitled to receive) from January 1 through the date of death. This is called the "cash method" standard — you include income actually received before death, not income that will be received after death.

Include in the final Form 1040:

• Wages, salary, and bonuses paid before death
• Business income earned and received before death
• Investment income (dividends, interest) received before death
• IRA or 401(k) distributions taken before death
• Social Security received before death

Do not include in the final Form 1040 (report on Form 1041 or the beneficiary's return instead):

• Wages earned but not yet paid at the date of death — this is "Income in Respect of a Decedent" (IRD) and belongs on the estate's Form 1041 or the recipient's own return when received
• Retirement account distributions taken after death by beneficiaries
• Investment income earned by estate assets after the date of death

This distinction is where most self-filers get confused. The estate becomes a separate taxpayer on the date of death. Income from that point forward belongs to the estate (Form 1041), not the decedent's final return.

Step 4: Apply Texas Community Property Rules

Texas is a community property state. This changes how income is allocated between spouses on the final return — and it has significant implications for which income appears on the final Form 1040 versus a separate return.

Under community property law, income earned during the marriage is split 50/50 between spouses regardless of who earned it. If the decedent was married and died partway through the year:

• Half of community wages, investment income, and business income belongs to the surviving spouse — even if earned entirely by the decedent
• The other half belongs to the decedent and appears on the final Form 1040

If the surviving spouse files jointly with the decedent (which is almost always preferable), this distinction does not matter — all of the community income is on the joint return anyway. But if for any reason the surviving spouse files separately, or if there is no surviving spouse and the decedent's executor files separately, the community property allocation determines what belongs on each return.

For the purpose of Form 1040 filing, the most common situation is straightforward: surviving spouse files jointly, includes all community income for the full year plus the decedent's separate property income through the date of death, and signs as surviving spouse.

Step 5: Choose the Filing Status

Married Filing Jointly: The surviving spouse can file jointly with the decedent for the year of death. The joint return uses both spouses' income, both spouses' deductions, and the joint standard deduction ($30,000 in 2025 approximately). This is usually the best choice unless the surviving spouse has significant individual losses or unique deductions that favor separate filing.

Qualifying Surviving Spouse: For the two years after the year of death, the surviving spouse may be able to file as "Qualifying Surviving Spouse" if they have a dependent child. This status keeps the married filing jointly tax rates for two additional years.

Single or Head of Household: If the decedent was not married, the executor files using "Single" or "Head of Household" (if the decedent had qualifying dependents).

Step 6: Complete the Return

Header: Write "DECEASED" after the decedent's name and enter the date of death in the appropriate field. The IRS provides this field specifically for this purpose.

Income: Report all income from January 1 through the date of death. If you are a surviving spouse filing jointly, report all community income for the full year plus the decedent's separate income through the date of death.

Deductions: The decedent's medical expenses are deductible even if paid after death, as long as they are paid within one year of death. This is a specific exception in the tax code that executors frequently miss.

Standard deduction: A decedent cannot take the standard deduction as a pro-rated amount — they get the full standard deduction for the year even if they died in January. This is favorable.

Signature: See Step 2. The appropriate person signs, with the notation "Personal Representative," "Filing as Surviving Spouse," or a similar description.

Attachments: Attach a copy of the death certificate if the IRS requests it (they do not always require it with the return, but have it ready). Attach Form 1310 if claiming a refund as a non-spouse, non-court-appointed filer.

Step 7: File and Track

Mail the return to the standard IRS address for your state. Allow 6–8 weeks for processing. If the return claims a refund, processing typically takes longer because the IRS performs additional verification when the taxpayer is deceased.

If you are using tax software, most major products (TurboTax, H&R Block, FreeTaxUSA) support deceased taxpayer returns and include the correct fields for the date of death and survivor/executor signature options.

After the Final 1040: What Comes Next

Filing the final Form 1040 is only the first tax obligation for most Texas estates. Once the 1040 is filed, executors need to evaluate:

Form 1041 (Estate Income Tax): If the estate earns $600 or more in income during administration — interest on bank accounts, dividends, rental income from property not yet sold — the estate must file a fiduciary income tax return. The estate has a separate EIN and faces compressed tax brackets: the top 37% rate applies at just $14,450 in taxable income (compared to $626,350 for individuals). Distributing income to beneficiaries via Schedule K-1 and passing it through to their personal returns often results in substantially lower overall tax.

Form 706 (Portability Election): Even when no federal estate tax is owed, filing Form 706 within 9 months of death preserves the deceased spouse's unused estate tax exemption — potentially $13.99 million in 2025 — for the surviving spouse's future estate. Skipping this is a permanent, irrecoverable loss.

Texas-Specific Obligations: Deferred property tax payoffs (if the decedent had an Over-65 deferral), franchise tax final reports (if the decedent owned a Texas business entity), and MERP documentation (if Medicaid-funded long-term care was received after age 55) all run on their own separate deadlines and are not addressed by Form 1040 at all.

The Texas Final Tax & Estate Tax Guide covers all of these obligations in sequence — Form 1040 through entity termination and MERP defense — in a single filing roadmap built specifically for Texas executors and surviving spouses.

Who This Is For

• Executors and surviving spouses who need to file a final Form 1040 for a Texas decedent and want to understand the process before deciding whether to hire a CPA
• Adult children managing a parent's estate with straightforward income (wages, Social Security, investment accounts)
• Surviving spouses who want to understand the community property income allocation rules before completing a joint return
• Anyone who was told "Texas has no state income tax" and assumed no state filing was needed (correct) but wants to understand the full federal process

Who This Is NOT For

• Estates with complex business income — closely held businesses, partnerships, or S-corporations require CPA-level expertise for the final return's income allocation
• Estates with large retirement account distributions that need careful IRD planning
• Situations where the decedent had significant prior-year returns under audit or IRS correspondence pending
• Executors who want a licensed professional to sign and bear liability for the return — you will need a CPA for that

Frequently Asked Questions

Does Texas have a state income tax return for deceased persons?

No. Texas levies no individual income tax at all, so there is no Texas state income tax return — final or otherwise. The only income tax return required is the federal Form 1040 covering the decedent's income through the date of death.

What is the deadline to file the final Form 1040 for a Texas decedent?

The standard deadline is April 15 of the year following death — the same deadline as a regular income tax return. If more time is needed, Form 4868 extends the deadline to October 15. If the estate later files Form 1041 (estate income tax), that return follows a separate calendar-year or fiscal-year schedule with its own deadlines.

What if the decedent died with no will and no executor appointed yet?

You can still file the final Form 1040. The person responsible for the decedent's property files the return, signing with a notation that they are acting for the decedent. If the return generates a refund, attach Form 1310 to claim it. Formal executor appointment is not required to file — it only becomes relevant for signing authority on more complex estate transactions.

Can I use TurboTax to file the final return for a deceased Texas resident?

Yes. TurboTax, H&R Block, and most major tax software products support deceased taxpayer returns. They include fields for the date of death, the signature designation, and Form 1310 for refund claims. However, they do not cover Form 706 portability elections, Form 1041 estate income tax, Texas franchise tax final reports, or other estate-specific obligations — those require separate guidance.

Should the surviving spouse always file jointly with the deceased spouse?

Almost always yes, for the year of death. Joint filing preserves the higher standard deduction, the lower married filing jointly tax brackets, and access to certain credits unavailable to single filers. The exception would be if the surviving spouse has significant separate losses or deductions that produce a better result on a separate return — which is uncommon and worth calculating before deciding.

What happens if I forget to include income earned before death?

The IRS will send a notice of underreporting if the income was reported to them (via W-2s, 1099s, or similar documents). You can file an amended return using Form 1040-X at any time within three years of the original filing deadline to correct the omission. Penalties and interest apply if the underreporting resulted in taxes owed.
