2026 tax year · Idaho
Rental host taxes in Idaho
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 Idaho that gap is worth $2,750 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 Idaho and the IRS charge against.

Earning more in Idaho
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 | Idaho tax | Total tax | Rate on gross |
|---|---|---|---|---|---|---|
| Part-time | $13,000 | $0 | $13,000 | $640 | $2,477 | 19.1% |
| Steady side income | $39,000 | $0 | $39,000 | $1,921 | $9,117 | 23.4% |
| Full-time | $63,000 | $0 | $63,000 | $3,103 | $15,832 | 25.1% |

Idaho specifics that change the number
Idaho is a community property state. In community property states, income earned during marriage is generally owned equally by both spouses. This affects QJV eligibility, MFS filing strategies, and retirement account contribution rules.
Local taxes on an Idaho 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 Idaho, 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.

Rental host tax questions in Idaho
How much should an Idaho host set aside?
About 16.3% of gross on the $39,000 example, $6,368 across self-employment tax, federal income tax and $1,423 to Idaho. Set aside from each payout rather than finding it in April.
Does the $39,000 on my 1099-NEC match what Idaho taxes?
No. Idaho taxes profit, not gross. After $10,100 of deductions the taxable figure is $28,900, so the Idaho bill is $1,423 rather than what gross alone would suggest.
