2026 tax year · Montana
Rental host taxes in Montana
Airbnb, Turo and the rest report your gross and withhold nothing. The gap between that and what you are actually taxed on is your costs, in Montana that gap is worth $2,693 in tax.
Take a driver who grossed $39,000 over 18,000 business miles. After mileage at 74.3 cents and the rest of the stack, worked through on the rental host page $10,100 comes off and $28,900 is left as taxable profit. That profit is what Montana and the IRS charge against.

Earning more in Montana
A single filer taking the standard deduction, this work as the only income, the calculator above handles the other filing statuses. Miles rise with earnings, so the deduction rises too, and the effective rate on gross climbs more slowly than it would for someone whose income grew without expenses attached:
| Volume | Gross | Mileage off | Taxable profit | Montana tax | Total tax | Rate on gross |
|---|---|---|---|---|---|---|
| Part-time | $13,000 | $0 | $13,000 | $0 | $1,837 | 14.1% |
| Steady side income | $39,000 | $0 | $39,000 | $1,046 | $8,242 | 21.1% |
| Full-time | $63,000 | $0 | $63,000 | $2,280 | $15,008 | 23.8% |

Montana specifics that change the number
On the 2026 rate itself: top rate reduced from 5.9% in 2025. Essentially a flat tax with small lower bracket.
Montana is one of the twelve states that still taxes Social Security benefits, which matters if you are drawing benefits alongside self-employment income.
Montana is also one of five states with no general sales tax, so the total tax picture is lighter than the income tax line alone suggests.
Local taxes on a Montana let
The income tax below is only part of it. Short-term lets attract occupancy, lodging or transient taxes levied by the city or county rather than Montana, often at rates that dwarf the state income tax. Some platforms collect and remit them; some collect only part; in some places the host is on the hook entirely. That is a local question this calculator cannot answer, and it is the one hosts most often get wrong.
On $28,900 of profit, what the states around Montana would charge:
| State | Its tax | vs Montana |
|---|---|---|
| North Dakota | $0 | −$700 |
| South Dakota | No income tax | −$700 |
| Wyoming | No income tax | −$700 |
| Idaho | $1,532 | +$831 |
- North Dakota would take $700 less, $0 against Montana's $700.
- South Dakota has no income tax at all, so the same work done there costs $700 less in state tax than it does in Montana.
- Wyoming has no income tax at all, so the same work done there costs $700 less in state tax than it does in Montana.
- Idaho would take $831 more, $1,532 against Montana's $700.
Rental host tax questions in Montana
How much should a Montana host set aside?
About 14.2% of gross on the $39,000 example, $5,548 across self-employment tax, federal income tax and $604 to Montana. Set aside from each payout rather than finding it in April.
Does the $39,000 on my 1099-NEC match what Montana taxes?
No. Montana taxes profit, not gross. After $10,100 of deductions the taxable figure is $28,900, so the Montana bill is $604 rather than what gross alone would suggest.
