Idaho does not have an inheritance tax
Idaho has no state inheritance tax. If you inherit money, property, or other assets from someone who died, you will not owe Idaho state tax on that inheritance. This applies whether the person who left you the inheritance lived in Idaho or elsewhere.
The federal government does have an estate tax, but it only affects very large estates. For 2024, the federal estate tax applies only to estates worth more than $13.61 million. Most people who inherit in Idaho will not encounter any tax on what they receive, either at the state or federal level.
Key Takeaways
- Idaho has no state inheritance tax, so inheritances are not taxed by the state regardless of the amount.
- The federal estate tax only applies to estates exceeding $13.61 million in 2024, which affects very few Idaho residents.
- Income you earn from inherited assets—such as interest, dividends, or rent—is taxable, but the inherited assets themselves are not.
- Some states do have inheritance taxes, so if you inherit from someone who lived elsewhere, check that state's rules.
The difference between inheritance tax and estate tax
An inheritance tax is paid by the person who receives the inheritance. An estate tax is paid by the estate itself before assets are distributed to heirs. Idaho has neither. Some states have one, some have both, and some have neither—Idaho falls in the "neither" category.
The federal estate tax is an estate tax, not an inheritance tax. It is owed by the estate of the person who died if the total value of their assets exceeds the threshold. The executor of the estate pays it from estate funds before distributing money to heirs. Because the threshold is very high, most estates in Idaho do not owe it.
What happens if you inherit from someone in another state
If the person who left you money or property lived in a state that has an inheritance tax, you may owe that state's tax on your inheritance. States with inheritance taxes include Iowa, Kentucky, Maryland, Nebraska, New Jersey, Pennsylvania, and Tennessee. The rules vary by state and by your relationship to the person who died.
You will need to check the tax laws of the state where the person lived, not where you live. If you inherited from someone in Pennsylvania, for example, you would follow Pennsylvania's inheritance tax rules, even though you live in Idaho and Idaho has no such tax. The executor or attorney handling the estate can tell you whether the estate owes tax in that state.
Income from inherited assets is still taxable
While the inherited assets themselves are not taxed in Idaho, any income you earn from those assets is taxable. If you inherit a savings account and earn interest on it, that interest is taxable income. If you inherit rental property and collect rent, that rent is taxable income. If you inherit stocks and receive dividends, those dividends are taxable income.
You report this income on your federal tax return and, if you owe Idaho state income tax, on your Idaho return as well. The inheritance itself is not the taxable event—the income generated afterward is. Keep records of what you inherited and when, so you can track which income came from inherited assets.
Federal estate tax thresholds and what they mean
The federal estate tax threshold changes each year. In 2024, it is $13.61 million per person. This means an estate must be worth more than $13.61 million for the federal government to tax it. A married couple can combine their thresholds, so a married couple's threshold is roughly double that amount.
If someone dies with an estate worth $5 million, no federal estate tax is owed. If someone dies with an estate worth $20 million, federal estate tax is owed on the amount above the threshold. The threshold is set to drop significantly in 2026 unless Congress changes the law, so estates that are safe now may not be safe in a few years. An estate attorney or tax professional can help you understand whether a specific estate might owe federal tax.
What you need to do as an heir in Idaho
As an heir in Idaho, you do not need to file any special tax forms just because you inherited. You do not owe Idaho inheritance tax. However, you should keep records of what you inherited and when you inherited it, because this affects your tax basis in the asset.
If you later sell inherited property or assets, your tax basis is usually the fair market value on the date the person died, not what they originally paid for it. This is called a "step-up in basis" and it can significantly reduce any capital gains tax you owe if you sell. For example, if someone bought a house for $100,000 and it was worth $300,000 when they died, your basis is $300,000. If you sell it for $310,000, you owe capital gains tax on only $10,000, not $210,000. Keep the death certificate and a document showing the property's value on the date of death.
When to talk to a tax professional
You should talk to a tax professional if the estate is large, if the person who died lived in multiple states, or if the estate includes business interests or complex assets. You should also consult a professional if you inherited from someone who lived in a state with an inheritance tax, because you will need to understand that state's rules.
An estate attorney or CPA can review the situation and tell you what forms need to be filed, what records to keep, and whether any taxes are owed. Many estates in Idaho require no special tax filing at all, but it is worth confirming rather than guessing.
Frequently Asked Questions
Do I have to report my inheritance to Idaho?
No. Idaho has no inheritance tax and does not require you to report inheritances to the state. You do not file any special form with Idaho just because you inherited money or property. However, if the inherited assets generate income, you must report that income on your tax return.
What if the person who died owed taxes?
The debts of the person who died are paid from their estate before assets are distributed to heirs. If the estate does not have enough money to pay all debts and taxes, heirs generally do not have to pay the difference from their own money. The executor handles this process.
Is there a time limit to inherit in Idaho?
Idaho law sets time limits for heirs to claim their inheritance, but these are usually several years. If you believe you are may have access to to an inheritance, contact the executor or the attorney handling the estate. They can tell you the important date and what you need to do.
Do I owe federal tax on a small inheritance?
No. The federal estate tax only applies to estates over $13.61 million in 2024. Inheritances below that amount do not trigger federal estate tax. You may still owe income tax on earnings from the inherited assets, but not on the inheritance itself.
What if I inherited property outside Idaho?
You follow the tax rules of the state where the property is located. If you inherited real estate in California, you follow California's rules. If you inherited a bank account in New Jersey and that state has an inheritance tax, you may owe that tax. The executor or attorney can advise you on which state's rules explore.
