Trust and estate tax
Trust and estate tax checklist
A trust or estate return follows the money from the entity to the beneficiaries. The Form 1041 needs the trust document, the income the entity received, the expenses it paid, and a record of what was distributed to each beneficiary. This checklist covers the common documents for a 2026 Form 1041, including the estate-specific records that only apply in the year of death.
Who sends itSent by the tax preparer to the trustee, executor or estate administrator after the year ends and before the Form 1041 and the beneficiary Schedules K-1 are prepared.

What firms get wrong
- Missing the trust document or will, which decides how income and distributions are allocated.
- Reporting distributions to beneficiaries without the beneficiary tax IDs, which delays the K-1s.
- Treating a distribution in kind as a cash distribution and losing the property's basis.
- Forgetting the date-of-death valuation for an estate, which makes the later gain or loss wrong.
- Filing the final return without the termination date and the final distribution records.

Questions about this checklist
Who files Form 1041?
The fiduciary of a domestic estate, trust or bankruptcy estate files Form 1041 to report the entity's income, deductions and distributions. The trustee or executor is usually the fiduciary.
When is a trust or estate return due?
A calendar-year trust or estate files Form 1041 by April 15, 2027 for tax year 2026. A fiscal-year entity files by the 15th day of the fourth month after its year ends. An extension changes the filing date but not the date the tax is due.
What is a beneficiary K-1?
Schedule K-1 (Form 1041) reports each beneficiary's share of the entity's income, deductions and credits. The fiduciary gives a copy to each beneficiary for use on the beneficiary's own return.
What happens when a trust or estate ends?
The final return reports the income and deductions through the termination date and the final distributions to the beneficiaries. Ask for the termination date and the final distribution records.
Does a small trust still need to file?
A trust may not need to file a separate return if it is a grantor trust and the grantor reports the income, or if its income is below the filing threshold. The trust document and the income decide, so ask the preparer before skipping the return.
