Taxes are one of the least-discussed parts of selling a home — and one of the most important. Whether you’re selling a primary residence, an investment property, or an inherited home in Billings, the tax implications can significantly affect how much you actually walk away with.

This guide covers the key tax concepts Montana sellers need to understand. It is not a substitute for advice from a qualified CPA or tax attorney — but it gives you a solid foundation before those conversations.

Capital Gains Tax: The Basics

When you sell a property for more than you paid for it, the profit is generally subject to capital gains tax. Capital gains are taxed at either the short-term or long-term rate depending on how long you’ve owned the property.

Short-term capital gains apply to properties held for one year or less. These gains are taxed as ordinary income — meaning your federal rate could be as high as 37% depending on your bracket.

Long-term capital gains apply to properties held for more than one year. Federal long-term capital gains rates are 0%, 15%, or 20%, depending on your taxable income. Most Billings homeowners fall into the 15% bracket.

Montana taxes capital gains as ordinary income at the state level. Montana’s top income tax rate is 6.75% (for income over $20,500 for single filers). There is no separate Montana capital gains rate — it’s simply added to your other income and taxed accordingly.

The Primary Residence Exclusion (Section 121)

The single most valuable tax benefit available to homeowners is the Section 121 exclusion, which allows you to exclude a substantial portion of capital gains from federal tax when selling your primary residence.

To qualify, you must meet two tests:

Ownership test: You must have owned the home for at least 2 of the past 5 years.
Use test: You must have used the home as your primary residence for at least 2 of the past 5 years.

If you qualify, you can exclude up to:

$250,000 in capital gains if you file as single
$500,000 in capital gains if you file jointly as a married couple

Example: You and your spouse bought a home in Billings in 2015 for $200,000 and sell it today for $420,000. Your gain is $220,000. Because you’ve lived there as your primary residence, you qualify for the full $500,000 exclusion — meaning you owe no federal capital gains tax on this sale.

Montana does not have an equivalent state-level exclusion. However, because the federal exclusion reduces your adjusted federal AGI, your Montana tax liability may also be reduced. A Montana CPA can walk through the specifics for your situation.

What If You Don’t Meet the 2-Year Rule?

Life doesn’t always wait for tax rules. Divorce, job relocations, health issues, and financial hardship can all force a sale before the 2-year threshold.

The IRS allows a partial exclusion if the sale was due to certain qualifying circumstances:

Change in employment location (you or your spouse must move at least 50 miles)
Health reasons (sale required for medical treatment or care)
Unforeseen circumstances (job loss, death of a co-owner, multiple births from the same pregnancy, etc.)

The partial exclusion is calculated proportionally based on how long you owned and used the home before selling. Talk to a tax professional if you’re in this situation.

Investment Properties and Rental Properties

If you’re selling a rental property or investment property in Billings, the tax picture is more complex.

Depreciation recapture: If you’ve taken depreciation deductions on the property (which is required for rental properties), those deductions will be “recaptured” at a federal rate of up to 25% when you sell. This applies even if you’re below the long-term capital gains threshold.

No primary residence exclusion: The Section 121 exclusion applies only to your primary residence. If you never lived in the rental property as your primary home, the exclusion doesn’t apply to the full gain.

1031 exchange: If you want to defer capital gains from the sale of an investment property, you may be able to use a Section 1031 like-kind exchange — reinvesting the proceeds into another investment property within specific time limits. This is a complex strategy that requires careful planning with a qualified intermediary.

Inherited Property: The Stepped-Up Basis Advantage

One of the most favorable tax treatments in real estate involves inherited property. When you inherit a home, your cost basis is “stepped up” to the property’s fair market value at the date of the previous owner’s death.

This means if your parent purchased a Billings home for $85,000 in 1988, and it was worth $350,000 when they passed, your basis is $350,000 — not $85,000. If you sell the home for $355,000, you only owe capital gains tax on the $5,000 difference.

This stepped-up basis erodes over time if the property’s value changes from the date-of-death appraisal. Selling relatively quickly after inheritance is often the most tax-efficient approach.

Does a Cash Sale Change My Tax Liability?

No — the method of sale doesn’t affect your capital gains tax. Whether you sell to a cash buyer like Canyon Creek Property Solutions or through a traditional MLS listing, the taxable gain is calculated the same way: sale price minus your adjusted cost basis.

What a cash sale does affect is your net proceeds:

No agent commission (saves 5–6%): On a $300,000 home, that’s $15,000–$18,000 you keep.
No closing costs paid by seller: We typically cover standard closing costs.
No repair credits: You sell as-is. In a traditional sale, repair requests after inspection often result in price reductions.
Faster closing: Less time means lower holding costs (mortgage payments, taxes, insurance, utilities).

When you factor in all of these savings, a cash offer that appears lower on paper often results in comparable or higher net proceeds than a listing — especially for homes that need significant work.

Montana-Specific Considerations

Property tax proration: Montana property taxes are paid in arrears. At closing, property taxes will typically be prorated between you and the buyer based on the closing date. Your final settlement statement will reflect this credit or debit.

Montana income tax on capital gains: As noted above, Montana taxes capital gains as ordinary income at rates up to 6.75%. This is on top of any federal capital gains tax. High-gain sales can result in a significant combined state and federal tax bill — another reason to confirm your eligibility for the primary residence exclusion before closing.

Homestead exemption: Montana’s homestead exemption protects a portion of a primary residence’s value from creditor claims, but it does not reduce capital gains tax liability on a sale.

Taxes are complicated, and every homeowner’s situation is different. Before you sell your Billings home — through any method — talk to a Montana CPA or tax attorney about your specific capital gains exposure.
