Filing your taxes isn’t something most people consider to be easy, so when you have to file taxes for a recently deceased family member, it can feel downright Herculean. Between the emotional toll and the mountain of paperwork, many executors and surviving spouses find themselves staring at a pile of forms, wondering where to even begin.

At Shelter, we believe legacy planning is about more than just a Will — it’s about leaving a clear roadmap. Part of that roadmap involves navigating the IRS and filing those tax returns.

If you’re handling the taxes for a deceased loved one, here’s what you need to know about filing a final return and managing an estate.

1. The Filing Deadline is Still the Same

It’s a common misconception that a person’s death pauses their tax obligations.

In reality, the IRS expects taxes to be filed by the standard tax deadline (in most years, April 15) covering everything the deceased earned from January 1st until the date of their death.

2. A Surviving Spouse Can Still File a Joint Return

If you lost a spouse during the tax year, you can generally still file a joint return for that year (provided you haven’t remarried by December 31st).

This usually allows for a higher standard deduction and more favorable tax brackets during a difficult transition year.

3. Be Sure to Label “Deceased” Correctly

Transparency is key when communicating with the IRS.

If you are filing a paper return, you must write “Deceased,” the person’s name, and their date of death clearly across the top of the Form 1040.

If you’re using e-file software, look for the “Deceased Taxpayer” checkbox to ensure the return is processed correctly.

4. Know Exactly Who Signs the Return

The question of “who signs the tax return” depends on the legal setup.

• Court-Appointed Representative: If there is an executor or administrator, they sign.
• No Representative: On a joint return, the surviving spouse signs and notes “filing as surviving spouse.”
• Everything Else: You may need to attach a copy of the death certificate or court appointment papers.

5. Use Form 1310 to Claim a Refund

If the deceased person is owed a refund and you aren’t the surviving spouse or a court-appointed executor, you’ll need to file Form 1310.

This form allows you to claim the refund on behalf of the estate.

6. Managing Post-Death Income of $600+

Sometimes, the person’s assets (like stocks, a house, or a business) continue to earn money after they pass away. If that post-death income exceeds $600, you’ll need to file Form 1041 (Income Tax Return for Estates and Trusts).

Think of this as the “bridge” return between their life and the final distribution of assets.

7. Does the Death Tax Apply?

Most people don’t need to panic about the Estate Tax – sometimes called the “Death Tax.”

The Estate Tax only kicks in if the total value of the deceased’s assets is very high. For 2026, the federal exemption is roughly $15 million — though it’s always wise to check your specific state’s laws.

8. Maximize Medical Deductions

End-of-life care can be incredibly expensive.

The good news? Medical expenses paid before death can be deducted on the final return.

Even better: expenses paid after death (within one year) can often be “reached back” and treated as if they were paid when incurred.

9. The “Step-Up in Basis” Value

This may be the single best tax gift the IRS offers. If you inherit an asset (like a family home or a portfolio of stocks), its tax value is reset to the market value on the day the person died (called the Step-Up in Basis).

If your parents bought a house for $50k in 1970 and it’s worth $800k today, you don’t pay taxes on that $750k gain if you sell it right away.

10. The Power of a Digital Vault

The biggest hurdle in estate taxes isn’t the math; it’s the manhunt. Searching through filing cabinets for W-2s, 1099s, and previous returns adds unnecessary stress to a grieving family.

Using a tool like Shelter ensures your tax documents are organized and accessible. When you store your “tax life” in your Shelter, you aren’t just filing papers — you’re giving your future executor a 100-hour head start.

A Final Word of Advice

Tax laws for estates are nuanced and can change. While this guide provides a solid foundation, we always recommend consulting a CPA or a tax professional to ensure you’re checking every box.
