ET-85

New York State Estate Tax Certification

Required when an estate may be subject to NY estate tax. Reports the value of all assets and calculates any tax owed. Filed with the ET-117.

This form determines whether estate tax is owed.

The ET-85 requires a complete valuation of all estate assets — bank accounts, investments, property, and more. Underreporting triggers audits; overreporting costs the estate money. Accuracy matters.

When do you need this form?

The estate you're administering may exceed the NY exemption amount.
