When someone dies, the family is often trying to make practical decisions while carrying a heavy emotional load. Tax filings are rarely the first thing anyone wants to think about, but they can affect refunds, distributions to beneficiaries, trust administration, and the executor’s ability to close the estate cleanly.
The first step is to separate the tax picture into three possible taxpayers: the person who passed away, the probate estate, and any trust that becomes responsible for post-death income. Not every situation requires every return, but each should be reviewed before assets are distributed.
Start with the final individual income tax return
A person’s final individual income tax return generally covers January 1 through the date of death. For federal purposes, income earned or received through the date of death is reported on the final Form 1040. For California residents, the final California individual return is generally filed on Form 540 if a return is otherwise required.
The final return may include wages, retirement income, interest, dividends, business income, partnership or S corporation income, capital gains, and deductions paid before death. If the taxpayer was married, the surviving spouse may be able to file a joint return for the year of death, depending on the facts.
If a refund is due, it may be paid to the surviving spouse, personal representative, or other authorized person. In some cases, the person claiming the refund must file Form 1310, Statement of Person Claiming Refund Due a Deceased Taxpayer. If married filing jointly, the surviving spouse can also request the overpayment be applied to the next year’s estimated taxes.
Identify who has authority to act
Tax filings after death depend heavily on who has legal authority. That person may be an executor named in a will, a court-appointed administrator, or a successor trustee under a revocable living trust.
Early in the process, we generally asks for:
- Date of death
- Prior-year tax filings and notices
- Death certificate
- Will, trust agreement, or court appointment documents
- List of assets and how they were titled
- Income received before and after death
- Information about beneficiaries
- Details on any business interests, rental properties, retirement accounts, or investment accounts
This information helps determine which returns may be needed and which taxpayer should report each item of income.
Determine whether there is a living trust
If the person had a revocable living trust, the trust often becomes irrevocable at death. The successor trustee may need to obtain a new taxpayer identification number (EIN), update financial accounts, and begin tracking income and expenses separately from the decedent’s individual Social Security number.
If the trust earns income after death, retains assets, sells property, or makes distributions to beneficiaries, it may have a fiduciary income tax filing requirement. Federally, this is generally reported on Form 1041, U.S. Income Tax Return for Estates and Trusts. For California trusts, the corresponding return is generally Form 541.
The trustee should also expect beneficiary reporting to become part of the process. It is important to work with a tax advisor to determine whether trust income should be taxed at the trust level or passed through and taxed to the beneficiaries, based on the governing document and applicable tax rules. . If income is distributed or treated as distributed, beneficiaries may receive Schedule K-1 reporting their share of trust income, deductions, and credits.
Under the 65-Day Rule (IRC Section 663b), trustees and executors can distribute income during the first 65 days of the new calendar year and elect to treat those payments as if they were made on the last day of the preceding tax year
Determine whether probate is required
If assets were not held in trust, did not pass by beneficiary designation, and were not otherwise transferable outside probate, a probate estate may be created. The executor or administrator generally obtains an EIN for the estate and tracks post-death income and expenses.
A probate estate may also need to file federal Form 1041 and California Form 541 for income earned after the date of death until the estate is fully administered and distributed.
It is also possible to have both a trust and a probate estate. For example, some assets may have been titled in the trust while others remained outside it. In that case, each taxpayer may have separate reporting obligations.
Review whether a federal estate tax return is needed
A federal estate tax return, Form 706, is generally required only if the gross estate plus adjusted taxable gifts exceeds the filing threshold for the year of death. For 2026, the IRS lists the federal estate tax filing threshold as $15,000,000.
Even when Form 706 is not required because the estate is below the threshold, a married decedent’s estate may still evaluate whether to file Form 706 to elect portability of the deceased spouse’s unused exclusion amount for the surviving spouse. This can be a valuable planning decision for high-net-worth families, especially when asset values, future appreciation, prior gifts, or remarriage could affect the surviving spouse’s estate plan.
Avoid distributing too quickly
Before making final distributions, fiduciaries should confirm that tax filings, estimated taxes, notices, basis documentation, and beneficiary reporting have been addressed. Distributing assets too soon can create cash flow problems if the estate or trust later owes tax, needs amended reporting, or receives corrected Forms 1099.
Families should also preserve documentation showing date-of-death values, account ownership, beneficiary designations, and post-death income. These records may affect income tax reporting, fiduciary accounting, and future basis calculations when inherited assets are sold.
General guidance can help families understand the process, but tax filing obligations after death depend on the decedent’s assets, state residency, trust structure, income, beneficiaries, and timing of distributions. This article is not direct tax, legal, or financial advice.
