Executor's Guide to Ohio Inheritance Tax Forms

Being named executor of an estate in Ohio comes with a long list of responsibilities, and figuring out tax obligations is one of the most confusing parts. Many executors search for inheritance tax forms only to discover that Ohio's rules are not what they expected. Getting the tax side wrong can delay estate distribution and create personal liability, so understanding exactly which forms apply and which do not matters right from the start.

Does Ohio Have an Inheritance Tax?

Ohio eliminated its estate tax for deaths occurring on or after January 1, 2013. Before that, estates above a certain threshold owed a state tax. Today, there is no Ohio inheritance tax and no Ohio estate tax. If you are administering an estate for someone who died after that date, you will not file a state inheritance tax return in Ohio.

This catches many executors off guard. They search for Ohio inheritance tax forms expecting a state filing requirement, only to find that those forms no longer exist. Knowing this early saves time and prevents you from filing paperwork that the state does not accept.

What Tax Forms Does an Ohio Executor Actually Need to File?

Even though Ohio has no inheritance tax, executors still have tax duties. The forms you may need depend on the size of the estate, the types of assets involved, and whether the decedent had income in the final year of life. Common filings include:

IRS Form 1041 Federal income tax return for the estate or trust, required if the estate earns more than $600 in income after the date of death.
IRS Form 706 Federal estate tax return, only required if the gross estate exceeds the federal exemption threshold (currently over $13 million for individuals in 2024, though this amount is subject to change).
IRS Form 1040 The decedent's final personal income tax return for the year of death.
Ohio IT 1040 The decedent's final state income tax return if they had Ohio-source income.
Ohio IT 1140 Fiduciary income tax return if the estate earns Ohio-source income during administration.

When Would Federal Estate Tax Forms Apply?

Most Ohio estates will never need to file a federal estate tax return because the exemption is high. However, if the decedent's gross estate including real estate, retirement accounts, life insurance, and other assets exceeds the federal threshold, IRS Form 706 is required.

This form is lengthy and requires detailed valuations of all assets as of the date of death. Executors often work with a CPA or tax attorney on this filing because errors can trigger audits and penalties. If the estate is close to the threshold, it is worth getting a professional valuation rather than guessing.

What About Property in Other States?

Here is a situation that trips up many executors: the decedent lived in Ohio but owned property in a state that still has an inheritance tax. States like Pennsylvania, Kentucky, New Jersey, Maryland, Iowa, and Nebraska impose inheritance taxes. If the decedent owned real estate or other tangible property in one of those states, the estate may owe tax in that state regardless of Ohio's rules.

In that case, you would file the applicable inheritance or estate tax forms in the state where the property sits not in Ohio. This often requires hiring a professional who knows that state's tax code.

How Do You Handle the Decedent's Final Income Tax Return?

The decedent's final federal (Form 1040) and state (Ohio IT 1040) returns cover income earned from January 1 through the date of death. As executor, you file these returns on behalf of the deceased person. Any refund owed goes to the estate. If tax is owed, the estate pays it from estate assets.

Make sure you gather all W-2s, 1099s, and other income documents for the year of death. If the person died early in the year, you may need to request duplicate forms from employers and financial institutions. Our guide on completing Ohio estate inventory paperwork can help you track down and organize these records.

What Is an Ohio Fiduciary Income Tax Return?

After the date of death, the estate itself can earn income rental income from property, interest, dividends, or capital gains from selling assets. If the estate earns more than $600 in gross income during administration, you must file IRS Form 1041 (federal) and Ohio IT 1140 (state).

This is separate from the decedent's personal returns. The fiduciary return reports income earned by the estate as its own taxpaying entity. Distributions to beneficiaries are reported on Schedule K-1, which tells each beneficiary what portion of the estate's income to include on their personal return.

Common Mistakes Executors Make With Estate Tax Forms

Several errors come up repeatedly in Ohio estate administration:

Filing forms that no longer apply. Some executors waste time looking for Ohio estate tax forms that were discontinued in 2013. Others file federal Form 706 when the estate is well below the exemption.
Mixing up estate income and the decedent's income. Income earned before death goes on the decedent's final return. Income earned after death goes on the fiduciary return. Mixing these up creates filing errors.
Missing deadlines. The decedent's final return is due on the regular April 15 deadline. The fiduciary return follows a different schedule depending on the estate's tax year. Late filing triggers penalties and interest.
Forgetting to file when no tax is owed. Even if no tax is due, you may still need to file returns to report income or close out the decedent's tax accounts.
Failing to get a tax ID for the estate. Before filing a fiduciary return, you need an Employer Identification Number (EIN) from the IRS for the estate. This is separate from the decedent's Social Security number.

Mistakes in tax filings can also complicate the probate court paperwork you submit as part of estate administration.

Should You Hire a Tax Professional?

If the estate involves significant assets, multiple income sources, property in other states, or a federal estate tax filing, hire a CPA or tax attorney who handles estate matters. The cost of professional help is usually a legitimate estate expense paid from estate funds.

For smaller, straightforward estates a bank account, a house, minimal income after death you may be able to handle the tax filings yourself using IRS instructions and Ohio Department of Taxation resources. The Ohio Department of Taxation provides forms and guidance for fiduciary filings.

How Do Tax Filings Connect to the Overall Estate Process?

Tax obligations do not exist in isolation. They tie directly into your duties as executor. You need accurate asset inventories to calculate estate values. You need to settle debts and taxes before distributing assets to beneficiaries. And you need to file final returns before you can close the estate with the probate court.
