1. When Are Federal and New York Estate Tax Returns Required?
Federal and state rules differ. Beneficiary distributions do not determine filing duties.
Compare the 2026 Filing Thresholds
| Return | 2026 Threshold | Filing Measure |
|---|---|---|
| Federal Form 706 | $15 million | Gross estate plus adjusted taxable gifts and specific exemption |
| New York ET-706 | $7.35 million | Federal gross estate plus gifts included under state rules |
Federal Form 706
- 2026 Threshold$15 million
- Filing MeasureGross estate plus adjusted taxable gifts and specific exemption
New York ET-706
- 2026 Threshold$7.35 million
- Filing MeasureFederal gross estate plus gifts included under state rules
For a U.S. citizen or resident dying in 2026, Form 706 is generally mandatory above $15 million. It may also be filed to elect spousal portability, which New York does not recognize. Deductions may eliminate tax without removing the filing duty.
Check Domicile and Prior Gifts
A nonresident estate with New York real or tangible property may need ET-706 if the filing threshold is met. Domicile depends on residence history and other evidence, not just an address; Form ET-141 may be required. Under Tax Law §954, certain taxable gifts within three years before death are added to the New York gross estate unless an exception applies. Gifts made while the decedent was not a New York resident and certain out-of-state transfers require separate analysis. Check the gift date, the decedent's residency when it was made, and whether the property was already included in the federal estate. Compare deeds and Forms 709 with earlier gift and estate tax planning records.
2. Which Records Establish the Estate's Taxable Value?
A probate inventory may omit taxable assets. Ownership and valuation records establish the full picture.
Reconcile Nonprobate Assets
Joint accounts, insurance, retirement benefits, and some trusts may be taxable despite passing directly to beneficiaries. Inclusion can depend on joint-account contributions, policy ownership rights, or retained trust powers. Compare deeds, beneficiary designations, statements, and trust instruments with tax schedules. An account balance alone does not establish the taxable share. For life insurance, check who could change the beneficiary or borrow against the policy.
Support Real Estate and Business Appraisals
Federal law generally uses fair market value at death. IRC §2032 alternate valuation requires reduced gross estate value and tax liability, among other conditions. A later listing price may not establish the value at death. Real estate appraisals need comparable sales and property conditions. Business valuations need financial statements, debts, ownership restrictions, and support for discounts. Earlier estate tax strategy decisions do not substitute for evidence of value at death.
Verify Debts and Deductions
A deduction requires a valid legal basis and evidence of its amount. Useful records include:
- Mortgage and creditor balances at death.
- Funeral bills and estate administration invoices.
- Gift returns, deeds, and trust amendments.
- Instruments supporting marital or charitable deductions.
Distinguish debts at death from administration costs. IRC §642(g) generally bars deducting the same expense on both estate and estate income tax returns.
3. Where Are Returns Filed and When Are They Due?
Court-issued letters establish an executor's authority, not whether tax is due.
Separate the Agencies and Documents
Federal Form 706 goes to the IRS; ET-706 goes to the New York State Department of Taxation and Finance. The state generally requires a completed federal Form 706 with ET-706 even when no federal return is otherwise due. Form 706-NA may apply to nonresident noncitizens. Rockland County Surrogate's Court in New City handles probate, not tax returns. Retain appointment letters and filing confirmations.
Address Extensions before the Deadline
Both returns generally are due nine months after death. A timely federal Form 4768 usually grants a six-month extension to file. New York Form ET-133 allows an application to extend the time to file, pay, or both. Neither filing extension automatically delays tax payment. Interest may accrue even where extra payment time is granted. If assets are illiquid, assess payment options before the due date. A pending sale does not extend it.
4. What Errors Complicate Filing or Property Transfers?
Incorrect credits, missing assets, and liens can create problems after filing.
Apply State Credits and Elections Separately
The New York applicable credit phases out above its basic exclusion amount. For a 2026 death, it disappears when the New York taxable estate exceeds $7,717,500, or 105% of the exclusion. Federal spousal portability does not carry over. Certain marital deductions may require a separate New York QTIP election. Review elections on each return separately.
Check Liens before a Real Estate Closing
A New York estate tax lien can affect inherited property even if the estate ultimately owes no tax. When a release is required, Form ET-117 is submitted with the appropriate ET-30, ET-706, or ET-85 materials. The correct route depends on filing status and fiduciary appointment. A signed purchase contract does not release the lien. Match the application to the parcel and confirm whether the title company needs a recorded release before closing.
Respond to Notices Based on Their Purpose
A revised appraisal or omitted asset may require evidence or an amended return. Preserve filed schedules and supporting records. Examination and debt collection follow different procedures. If the IRS issues a bank levy notice, an IRS tax attorney can review collection procedures and response deadlines.
5. Frequently Asked Questions
Must an Estate File Form 1041 After Filing Form 706?
A domestic estate generally files Form 1041 if its annual gross income reaches $600 or any beneficiary is a nonresident alien. Form 1041 reports income earned after death, while Form 706 concerns federal estate tax. One return does not replace the other.
Does Selling Inherited Property Create Capital Gains Tax?
Possibly. Under IRC §1014, the basis of inherited property generally reflects fair market value at death, subject to exceptions. Adjusted basis, sale proceeds, and costs determine gain or loss. The seller reports the transaction.
6. Review Estate Tax Filing and Valuation Questions
An estate tax attorney serving Rockland County can examine filing duties, reported assets, and valuations. Bring domicile evidence, asset schedules, appraisals, Forms 709, prior filings, and agency notices. The firm's attorneys can compare federal and state requirements, assess disputed valuations or deductions, review elections, and identify lien-release steps before a property transfer.
