How to Complete New York Inheritance Tax Forms

If someone you love has passed away and left you property or assets in New York, you may have stumbled across the phrase "inheritance tax" and wondered which forms you actually need to file. Here's the first thing to know: New York does not have an inheritance tax in the traditional sense. What New York does have is an estate tax, and understanding the difference along with which forms apply and when can save you from costly mistakes during an already difficult time.

Does New York Actually Have an Inheritance Tax?

No. This is one of the most common points of confusion when someone dies and leaves behind an estate in New York. People often search for "New York inheritance tax form instructions" because the terms get used interchangeably in everyday conversation. But legally and tax-wise, these are two different things.

An inheritance tax is charged to the person who receives the assets. New York does not impose this tax. Instead, New York imposes an estate tax, which is charged against the estate itself before assets are distributed to beneficiaries. The distinction matters because it determines who is responsible for filing and paying and that responsibility typically falls on the executor or personal representative of the estate.

If you're serving as an executor, understanding your full scope of responsibilities is essential. Our guide on executor duties during probate in New York walks through what's expected of you from start to finish.

What Is the New York Estate Tax Return (Form ET-706)?

The primary form you'll need is Form ET-706, the New York State Estate Tax Return. This form must be filed if the total value of the deceased person's estate exceeds New York's estate tax exemption threshold.

As of 2024, the New York estate tax exemption is approximately $6.94 million (this amount is indexed to inflation and adjusts periodically). If the gross estate is valued at or below this amount, no estate tax is owed but you may still need to file the return in certain circumstances.

Here's the catch that trips people up: New York has what's commonly called the "estate tax cliff." If the estate exceeds the exemption amount by more than 5%, the entire estate becomes taxable not just the amount above the threshold. For example, if the exemption is $6.94 million and the estate is valued at $7.3 million (more than 5% over), the full $7.3 million is subject to tax, not just the $360,000 overage.

When Does the Estate Tax Return Need to Be Filed?

Form ET-706 is due nine months after the date of death. You can request a six-month extension using Form ET-133 if you need more time to gather the required information, but any tax owed is still due by the original nine-month deadline. Interest accrues on unpaid balances after that date.

If you're still working through the probate process, filing timelines can feel overwhelming. Our step-by-step guide to the NY probate process explains how estate tax filing fits within the larger sequence of events.

What Information Do You Need to Complete Form ET-706?

Gathering documentation before you start filling out the form will make the process much smoother. Here's what you'll typically need:

Death certificate certified copies are required
Will (if one exists), along with any codicils
Full inventory of assets real estate, bank accounts, investment accounts, retirement accounts, life insurance policies, business interests, personal property of significant value
Appraisals for real property and valuable personal property, using fair market value as of the date of death
Outstanding debts and liabilities of the decedent
Prior taxable gifts made by the decedent during their lifetime
Federal estate tax return (Form 706) if one was filed with the IRS
Trust documents if the decedent held assets in a trust

The form itself requires detailed schedules covering each category of assets and deductions. It mirrors many sections of the federal estate tax return but is filed separately with the New York Department of Taxation and Finance.

How Do You Actually File the Estate Tax Return?

Form ET-706 is filed with the New York State Department of Taxation and Finance. As of now, the form must be filed by mail New York does not offer e-filing for estate tax returns. You'll send it to:

NYS Department of Taxation and Finance
Estate Tax Audit Bureau
W.A. Harriman Campus
Albany, NY 12227

You should also file a copy with the Surrogate's Court in the county where probate is being handled, as the court may require proof of filing before issuing certain documents. If you need to obtain court records related to the estate, our guide on ordering New York probate court documents explains how to request what you need.

Do Beneficiaries Have to Pay Anything?

In New York, beneficiaries do not directly pay estate tax. The estate pays the tax before assets are distributed. This is different from states like Maryland or New Jersey, which do impose a direct inheritance tax on certain beneficiaries.

However, what beneficiaries do receive may be reduced because the estate tax was paid out of the estate's assets first. For example, if the estate owes $100,000 in estate tax, that amount comes off the top of the estate before the remaining assets are divided among the heirs.

There's one exception worth noting: if a beneficiary receives income from estate assets after the decedent's death such as rental income from inherited property that income is generally subject to income tax in the beneficiary's hands.

What Are the Most Common Mistakes People Make?

After helping many families navigate this process, here are the errors that come up most often:

Assuming no tax is owed because the estate "feels" small. The gross estate includes life insurance proceeds, retirement accounts, jointly held property, and certain trusts things people often leave out of their mental calculation.
Forgetting about prior taxable gifts. Gifts made within three years of death (in some cases) are added back into the estate's value for estate tax purposes. This is often called the "three-year add-back rule" and can push an estate over the exemption threshold.
Missing the filing deadline. The nine-month window goes by faster than most executors expect, especially when you're grieving and dealing with other probate tasks simultaneously.
Using incorrect asset valuations. The IRS and New York both expect fair market value as of the date of death not the original purchase price, not the assessed value for property tax purposes. Professional appraisals are often necessary for real estate, business interests, and collectibles.
Not filing at all. Some executors assume that if no tax is owed, no return is needed. While this is technically true if the estate is below the threshold, filing can still be a smart move if a portability election or protective filing is desired.

Many of these issues come up because executors are learning as they go. If you're in the early stages, reviewing how to probate a will in New York can help you anticipate what's ahead.

Is There a Way to Reduce the Estate Tax?

Several deductions and credits can reduce or eliminate the estate tax owed:

Marital deduction Assets passing to a surviving spouse are generally exempt from New York estate tax.
Charitable deduction Bequests to qualifying charitable organizations are fully deductible.
Administrative expenses Costs of estate administration, including executor fees, attorney fees, and accounting fees, are deductible.
Funeral expenses Reasonable funeral costs are deductible.
Debts and mortgages Outstanding obligations of the decedent reduce the taxable estate.
Family-owned business deduction New York provides a deduction for certain qualified family-owned business interests, subject to specific requirements.

These deductions are claimed on Form ET-706 itself, so proper documentation of each expense is critical.

What About Estates Below the Exemption Threshold?

If the estate is clearly below the exemption amount and no federal estate tax return is required, you likely won't need to file Form ET-706. But there's a gray area: if the estate is close to the threshold say within a few hundred thousand dollars it's worth filing a protective return. This ensures that if the state later audits and determines the estate's value was higher than initially reported, you've preserved your right to claim deductions and credits.

You can also file an ET-706 solely to document that no tax is due, which provides a clean record for the estate's files.

How Long Does It Take to Get an Estate Tax Closing Letter?

After you file Form ET-706, the New York Department of Taxation and Finance will review it. Processing times vary, but it typically takes several months to receive a closing letter (Form ET-90) confirming that no additional tax is owed. If the estate is complex or subject to audit, it can take significantly longer.

Until you receive the closing letter, some executors hesitate to make final distributions to beneficiaries. This is a judgment call distributing too early can create personal liability if additional tax is later assessed.

Do You Need Professional Help?

While technically anyone can fill out Form ET-706, the form is detailed and the stakes are high. Errors can result in penalties, interest, or overpayment of tax. For most estates that are anywhere near the exemption threshold or that involve real property, business interests, trusts, or significant lifetime gifts working with an estate attorney or CPA who handles New York estate tax returns is strongly advisable.

The cost of professional preparation is itself a deductible estate expense, which effectively reduces the net cost to the estate.
