Introduction

When a loved one passes away, most people expect to deal with grief—not the IRS. But as the executor of an estate, you may suddenly find yourself facing a stack of tax forms, deadlines, and legal obligations you didn’t know existed. It’s one of the most misunderstood parts of the probate process—and one of the most important.

Estate taxes and post-death filings are not just financial housekeeping. As executor, you’re legally responsible for making sure the estate complies with all federal tax requirements. That includes filing the deceased’s final income tax return, reporting income earned by the estate, and—though rare—paying any applicable estate taxes if the estate is large enough.

This guide was written to give you clarity, confidence, and control. You’ll learn what taxes an executor may need to file, when each return is due, how to avoid mistakes, and when to seek help from a tax professional.

Overview of an Executor’s Tax Responsibilities

As the executor of an estate, your role isn’t just ceremonial—it carries real legal and financial responsibilities. Among the most critical are tax filings. The IRS expects the estate to fulfill certain obligations, and you’re the one legally responsible for getting it right.

The Three Main Tax Responsibilities of an Executor:

• Final personal income tax return (Form 1040)
• Estate income tax return (Form 1041)
• Federal estate tax return (Form 706 – if applicable)

Each serves a different purpose, follows different rules, and may be due at different times. Missing a filing or misreporting income could result in IRS penalties, delays in probate, or even personal liability.

Final Individual Income Tax Return (Form 1040)

One of the first tax duties you’ll face is filing the deceased’s final income tax return. This includes all income earned from January 1 until the date of death and is filed using IRS Form 1040.

Key Details:

• Deadline: April 15 of the year after death
• Filing Status: “Single” or “Married Filing Jointly” depending on marital status
• Executor signs the return and may need to attach a death certificate and IRS Form 1310 to claim any refund

Use estate funds—not personal funds—to pay any balance due. A CPA can help calculate deductions, especially for medical expenses, retirement income, or capital gains realized before death.

Estate Income Tax Return (Form 1041)

After death, the estate may continue to earn income—interest, dividends, rental payments, capital gains. If the estate earns more than $600 in gross income after death, you must file Form 1041.

You’ll need an EIN (Employer Identification Number) for the estate before opening any estate accounts or filing returns. Apply for this online through the IRS website.

Form 1041 reports income earned during administration, and if income is passed on to beneficiaries, you must also issue Schedule K-1s to report what each heir received and what taxes (if any) they may owe.

Federal Estate Tax (Form 706)

This form is only required if the total value of the estate exceeds the federal exemption threshold—which is $13.61 million in 2024. Very few estates are large enough to trigger this filing.

If you believe your estate may be close to the limit—due to life insurance, real estate holdings, or business assets—consult a tax advisor immediately. This return must be filed within 9 months of the date of death, though a 6-month extension is available.

Note: Florida does not impose a separate state estate tax.

Common Tax Mistakes Executors Make (and How to Avoid Them)

• Missing filing deadlines for Form 1040 or Form 1041
• Failing to obtain an EIN for the estate
• Overlooking post-death income generated by estate assets
• Paying beneficiaries before settling taxes and debts
• Not keeping detailed records of income, distributions, and payments

Avoid these pitfalls by working closely with a CPA or estate attorney, especially if the estate is complex or includes income-producing assets.

When and Why to Consult a Tax Professional

Taxes are serious business—and the executor is personally responsible for getting them right. A good CPA can help with:

• Preparing and filing IRS forms correctly
• Calculating tax owed and managing distributions
• Avoiding underpayment penalties
• Minimizing liability through accurate accounting

Even if the estate is modest, consulting a tax professional provides peace of mind—and may prevent thousands in fines or delayed probate.

Final Thoughts – You Don’t Have to Figure This Out Alone

Handling taxes during probate can feel overwhelming—but it doesn’t have to be. As executor, you’re not expected to know every IRS rule. You just need to know when to ask for help.
