When a loved one passes away in North Dakota, executors quickly discover that settling an estate involves more than just distributing assets. One of the most pressing concerns is whether the estate owes inheritance tax. North Dakota is one of a handful of states that still imposes a separate inheritance tax, and executors are directly responsible for getting it right. Miscalculate the tax or miss a deadline, and the estate and you as executor could face financial penalties. Understanding the North Dakota inheritance tax guidelines for executors upfront can save you time, stress, and money.

Do Estates Have to Pay Inheritance Tax in North Dakota?

Not every estate pays inheritance tax in North Dakota. The tax is imposed on the share passing to each beneficiary, not on the total estate value. If the decedent was a North Dakota resident, the tax applies to all property they owned, wherever located. For non-residents, only real estate and tangible personal property situated in North Dakota get taxed.

Before you can even calculate the tax, you’ll need to gather the necessary probate documentation that proves asset ownership and valuation. For detailed guidance on what that looks like, see managing probate paperwork for North Dakota estates. Keep in mind that certain small estates may qualify for a simplified process but the inheritance tax still needs to be addressed if a return is required.

How Are Beneficiaries Taxed Under the North Dakota Inheritance Tax Law?

The tax rate depends on the beneficiary’s relationship to the decedent. North Dakota groups beneficiaries into four classes, and each class has its own exemption amount and tax rate brackets. Class A beneficiaries spouses, children, grandchildren, parents, grandparents receive the most favorable treatment. In fact, a surviving spouse is entirely exempt from North Dakota inheritance tax.

For other lineal relatives (Class A), the first $300,000 of value passing to them is tax-free, with rates starting at 1.00% for amounts over that threshold. The rates then rise in steps up to 8.25% for very large inheritances. Class B beneficiaries include siblings and their descendants, with a lower exemption of $60,000 and rates from 1.25% to 10.25%. Class C covers everyone else, such as nieces, nephews, aunts, uncles, and unrelated friends their exemption is just $15,000 with rates from 2.00% to 12.50%. Class D includes for-profit organizations, which get no exemption and face rates from 4.00% to 16.50%.

These exemption amounts and rates are current as of 2025, but executors should verify the latest figures on the Tax Commissioner’s inheritance tax page. A small change can affect the bottom line.

When Is the Inheritance Tax Return Due for North Dakota Estates?

The executor must file Form 93, the North Dakota Inheritance Tax Return, within 18 months of the decedent’s date of death. But you don’t have to wait that long to get started. An informal “preliminary report” is often due within 90 days if the estate exceeds the exemption threshold. This report isn’t the final return it just notifies the state that a taxable estate exists and gives you time to assemble valuations.

If you need more time, file for an extension before the 18-month deadline. Extensions are not granted automatically, and interest starts accruing on any unpaid tax from nine months after the date of death.

What Documents Do Executors Need to Complete the Return?

To prepare the return, you’ll need a complete inventory of assets and their date-of-death values. That means real estate appraisals, bank and brokerage statements, life insurance proceeds payable to the estate, and records of jointly owned property. You also need a list of all beneficiaries and their class designations.

Executors often find that reviewing the instructions for filing the North Dakota inheritance tax return helps them understand how to properly classify beneficiaries and apply the correct exemptions. Missing a small detail like a CD with a payable-on-death designation can lead to an audit or penalty.

Common Errors Executors Make When Preparing the Inheritance Tax Filing

One frequent slip is failing to realize that gifts made within three years of death may be pulled back into the taxable estate. Another is misclassifying a beneficiary for instance, treating a step-grandchild the same as a biological grandchild, which can change the exemption and rate.

Some executors also forget to claim deductions for funeral expenses, debts, and administrative costs before calculating the net taxable share for each beneficiary. The estate is allowed to deduct these expenses, which lowers the total value subject to tax. If you skip this step, the estate overpays.

When you’re unsure about what forms to use, digging through the available official estate administration forms for North Dakota can clarify what schedules attach to the main return. Using outdated forms from prior years will cause a rejection.

Practical Tips for Staying on Top of Inheritance Tax Obligations

Start the valuation process early. Real estate appraisals and business interest valuations take time, and you can’t file an accurate return without them. Send out beneficiary notification letters as soon as practical so you know exactly who will inherit what.

Keep a separate estate bank account to hold cash for taxes. The estate pays the inheritance tax, not the individual beneficiaries, so having liquidity prevents a scramble. Also remember that the inheritance tax return and the federal estate tax return (if required) are separate filings. North Dakota does not have its own estate tax, only the inheritance tax.

What Happens If the Estate Can’t Pay the Tax Right Away?

If the estate lacks enough cash to cover the inheritance tax, you can request an installment payment plan. The state may allow the tax to be paid over several years with interest, but you need to submit a formal request and provide security. Failing to file a return or pay the tax on time triggers penalties of 5% per month up to 25% of the tax due, plus interest.

When the estate includes real property that must be sold to generate cash, you’ll want to coordinate the tax payment timeline with the sale. In some cases, you can withhold the tax from the property’s distribution to the beneficiary but only if properly documented. Pay close attention to the estate settlement requirements that dictate the order in which debts, taxes, and distributions must be satisfied.

Next Steps: A Quick Checklist for Executors

Take these steps to handle the inheritance tax filing without unnecessary headaches:

• Identify all beneficiaries and their North Dakota inheritance tax class.
• Collect date-of-death values for every asset.
• Apply the correct exemption for each beneficiary’s share.
• Deduct allowed funeral, debt, and administration expenses.
• File the preliminary report within 90 days if required, and the final Form 93 within 18 months.
• Send payment with the return or arrange an installment plan if needed.
• Keep copies of everything and maintain a record of correspondence with the Tax Commissioner.

Staying organized from day one makes all the difference. When in doubt, consulting an accountant or attorney familiar with North Dakota probate and inheritance tax can help an executor avoid personal liability for mistakes.
