Estate Administration
Tax Compliance

The full compliance picture

When a client dies, the tax obligations that follow are extensive and interdependent. Missing a step early in administration can create problems that compound for years. Below is the sequence of what needs to happen, roughly in the order it needs to happen, from the first week through final distribution.

Step 1: EIN and initial setup

The estate needs its own EIN before any returns can be filed or accounts can be opened. If a revocable trust is involved, it also needs a new EIN at death, unless a Section 645 election will be made (which allows the trust to use the estate’s EIN and fiscal year).

This is also when the fiscal year election should be evaluated. The choice is made on the estate’s first Form 1041 and is permanent. The right year-end can defer beneficiary income by up to 11 months and maximize the two-year estimated tax penalty exemption. The decision needs to be made before the first return is prepared, not after.

Step 2: Transcript review and cleanup

With the estate established, the next step is pulling IRS transcripts for the decedent: account transcripts, return transcripts, and wage and income records. These reveal unfiled returns, outstanding balances, open audits, and any other issues the decedent left behind. State tax records should be pulled at the same time.

If there are problems (unfiled prior-year returns, unpaid balances, unresolved notices), they need to be addressed early. An estate cannot close cleanly with outstanding federal or state tax liabilities, and the executor or trustee has personal liability for distributions made before taxes are paid. We respond to notices, file delinquent returns, negotiate installment agreements or offers in compromise where appropriate, and get the decedent’s tax history resolved.

Step 3: Accounting and reporting

Before any returns can be prepared, the accounting foundation needs to be in place. The tax returns draw from these records, not the other way around:

• Asset inventory at the date of death, with valuations for each asset
• Income and expense tracking throughout administration, for both the estate and any related trusts
• Distribution records showing what was paid to each beneficiary and when
• Court accountings, whether formal (required by the court) or informal (provided to beneficiaries voluntarily)
• Reconciliation of fiduciary accounting income with taxable income, which often differ
• K-1 preparation that ties to both the tax returns and the accounting records

For professional fiduciaries, clean accounting records are not optional. They protect you from surcharge claims, satisfy court requirements, and make the annual or final accounting straightforward. This accounting is maintained throughout the life of the estate and any related trusts.

Step 4: Final Form 1040

The decedent’s final individual return covers January 1 (or the start of their tax year) through the date of death. Income earned after death belongs on the estate’s Form 1041, not the final 1040.

Key items on the final return: filing status in the year of death, medical expenses (election to deduct on the 1040 or the 706), income in respect of a decedent (IRD), and any elections that need to be made. If the decedent made gifts during the year, a final Form 709 is also due, typically filed alongside the 706.

Step 5: Section 645 election and trust filings

Death triggers changes in trust filing obligations that need to be coordinated with the estate’s compliance:

• Revocable trusts become irrevocable at the grantor’s death. Unless a Section 645 election is made, the trust needs its own EIN and files its own Form 1041 on a calendar year.
• Section 645 election allows the revocable trust to be treated as part of the estate for tax purposes. The trust uses the estate’s EIN and fiscal year, and all income is reported on a single 1041. This election is made on the estate’s first 1041 and requires agreement between the executor and the trustee.
• Grantor trust status ends at death. A trust that was previously reported on the grantor’s 1040 must now file its own return.
• Testamentary trusts created by the will begin filing once they are funded.
• Existing irrevocable trusts (ILITs, special needs trusts, dynasty trusts) may need updated beneficiary designations, amended K-1 treatment, or changes in distribution planning depending on the trust terms.

When multiple trusts and an estate are all active at the same time, coordinating the filings, K-1s, and distribution timing is critical.

Step 6: Form 1041 series

The estate’s first 1041 covers the period from date of death through the chosen fiscal year-end. Subsequent 1041s are filed annually until the estate closes. If a Section 645 election was made, the revocable trust’s income is included on the estate’s 1041 rather than filed separately.

K-1s are issued to beneficiaries for each filing period. The character of income (ordinary, capital, tax-exempt) flows through to the beneficiary, and the amounts depend on whether distributions were made during the period and how distributable net income is allocated. Each trust that files its own 1041 also issues its own K-1s.

Step 7: Form 706 and basis reporting

The federal estate tax return is due nine months after the date of death, with an automatic six-month extension available. Even if no estate tax is owed, a 706 may be required to elect portability (DSUE) for the surviving spouse.

Once the 706 is filed, Form 8971 must be sent to the IRS and to each beneficiary within 30 days. This reports the basis of inherited assets and triggers the basis consistency requirement: beneficiaries must use the values reported on the 706 as their basis.

Step 8: Prompt assessment and closing

When the estate is approaching closure, the executor can request prompt assessment to shorten the statute of limitations and allow the estate to close sooner:

• Form 4810 (Request for Prompt Assessment) covers the decedent’s income tax returns (final 1040, prior-year returns) and the estate’s 1041s. It shortens the assessment window from three years to 18 months.
• Form 5495 (Request for Discharge from Personal Liability under Section 2204) covers the estate tax. It asks the IRS to make a final determination on the 706 and discharge the executor from personal liability for estate tax.

Filing both forms allows the estate to close without the risk of the IRS coming back years later with an additional assessment on either the income or estate tax side. For estates with significant assets or complex filings, this is standard practice.

The final 1041 is filed for the estate’s last fiscal period. Any excess deductions pass through to beneficiaries under Section 642(h). If a 706 was filed, the IRS issues an estate tax closing letter confirming no additional estate tax is due. Once all liabilities are resolved and the closing letter (if applicable) is received, final distributions can be made.
