For many families in Montana, inheritances represent the transfer of property, ranchland, investments, or long-held family businesses across generations. As residents navigate the estate planning and wealth transition process, one question consistently rises to the top: Are Montana inheritances subject to capital gains taxes?
This is an important topic for families in Billings and across Big Sky Country. Especially as property values rise, investment portfolios grow, and federal tax rules continue to evolve. In this guide, we break down how capital gains taxes work on inherited assets, how Montana’s tax laws come into play, and what families should consider when managing inherited wealth.
Montana Has No Inheritance or Estate Tax
Let’s start with some clarity: Montana does not have an inheritance tax or a state-level estate tax.
Montana repealed its state inheritance tax in 2005. That means beneficiaries receiving property (such as a home, ranch, land, or investments) do not pay taxes simply because they inherited it.
While Montana imposes no inheritance tax, federal laws may still apply, depending on the estate’s size. The federal estate tax exemption for 2025 and beyond is subject to potential changes, making it important to stay informed when planning for future generations. The IRS provides current exemption amounts and federal estate tax rules.
Capital Gains Taxes Apply Only When You Sell an Inherited Asset
Even though Montana doesn’t tax inheritances directly, capital gains taxes can come into play when inherited property is sold.
Capital gains tax is assessed on the increase in value of an asset from when you acquired it to when you sold it. For inherited property, this value is not measured from when the original owner purchased it. Instead, it uses what’s known as a “step-up” in basis.”
Understanding the Step-Up in Basis
A step-up in basis is one of the most significant tax benefits associated with inherited assets.
Here’s how it works:
- When an individual passes away, most inherited assets receive a new cost basis equal to their fair market value on the date of death.
- If the heir later sells the asset, capital gains tax is calculated only on the difference between:
- The sale price, and
- The stepped-up basis (the value at the time of inheritance)
Example:
A parent bought land in Yellowstone County decades ago for $50,000. At the time of their passing, the land is valued at $600,000.
- The heir’s “basis” is now $600,000, not $50,000.
- If the heir sells the land for $620,000, capital gains tax applies only to the $20,000 gain.
This tax treatment can significantly reduce the taxable amount on inherited assets. The IRS website offers more details on cost basis rules.
Does Montana Tax Capital Gains?
Yes, Montana does tax capital gains at the state level, but with some nuances.
Montana treats capital gains as part of taxable income, subject to state income tax. However, residents may benefit from the Montana Capital Gains Tax Credit, which offers a partial reduction on capital gains earned within the state.
This means that if you inherit property in Montana and later sell it, the portion of the gain may receive preferential tax treatment compared to ordinary income.
Common Scenarios for Montana Families
- Inheriting a Home in Billings or Local Real Estate
Homes, ranches, or recreational properties often represent a large share of Montana inheritances. With the step-up in basis, heirs generally owe little or no capital gains tax if they sell soon after inheriting the property.
If the property is held for years and appreciates in value, capital gains are more likely when it is eventually sold.
- Inheriting Ranchland or Agricultural Property
Agricultural land in Yellowstone, Carbon, Stillwater, and surrounding counties can rise in value significantly over long periods. The step-up helps reduce potential capital gains, but selling acreage after additional growth may still trigger taxes.
Land transfers often involve legacy considerations, so many Montana families review planning options (such as LLCs, family partnerships, or conservation easements) to support long-term goals.
- Inheriting Stocks, Bonds, or Investment Accounts
Inherited investment portfolios also receive a step-up in basis.
If beneficiaries sell shortly after inheriting the assets, capital gains may be minimal. Holding the assets long-term may lead to future capital gains, depending on market performance.
- Inheriting a Business
Many Montana businesses, particularly those in construction, agriculture, and energy, remain family-owned for generations. Business interests often receive a step-up in basis, though valuation can be more complex.
Selling a business or its assets later is more likely to generate capital gains, depending on structure and market conditions.
Federal vs. State Capital Gains on Inheritances
Federal Capital Gains
The IRS taxes capital gains at either short-term or long-term rates. Inherited assets are always treated as long-term holdings, even if they were held only one day after being inherited.
This is beneficial because long-term capital gains rates are typically lower than ordinary income tax rates.
Montana Capital Gains
Montana income tax rates apply, but the state offers a Capital Gains Tax Credit that may ease the impact. Montana does not distinguish between short-term and long-term gains for state purposes, the credit simply reduces the total amount owed.
Strategies to Consider When Handling Inherited Assets
Families in Billings often want to make informed choices about inherited wealth. Here are some commonly used approaches:
Timing the Sale
If the asset has appreciated since the date of death, reviewing the tax implications before selling can be beneficial. Some families choose to sell quickly to minimize gains; others prefer to hold if long-term appreciation aligns with their financial goals.
Evaluating Property Use
For inherited real estate, deciding whether to sell, rent, occupy, or hold as an investment property carries tax considerations.
Co-Inheriting Property
Siblings inheriting property together may face decisions about buyouts, co-ownership agreements, or selling jointly. Capital gains outcomes often differ depending on how each option is structured.
Estate Planning for the Next Generation
Many clients choose to reorganize inherited assets (such as transferring investments into trusts or restructuring property ownership) to simplify future generational transfers.
The Bottom Line: Montana Inheritances and Capital Gains Taxes
Montana makes inheritance simpler by not imposing a state inheritance or estate tax. While receiving an inheritance does not trigger tax, selling inherited assets may create capital gains, federal, state, or both, depending on appreciation after the step-up in basis.
For residents in Billings and throughout Montana, understanding how these rules interact can make a meaningful difference when managing inherited property or planning multigenerational wealth transitions.
