Gig Workers in Idaho: taxes and retirement for 2026
For rideshare and delivery drivers, shoppers and app-based workers in Idaho. Idaho has a flat 5.3% state income tax for 2026. Here are the 2026 rules, a worked example and the official sources.
Idaho rules for gig workers
- State income tax (2026)
- Idaho has a flat 5.3% state income tax for 2026. Idaho Code 63-3024 taxes Idaho taxable income at 5.3% above an inflation-indexed zero bracket (the 2025 Form 40 instructions use $4,811 for single filers; the 2026 amount was not yet published). No 2026 enacted bill changed the rate. Anyone required to file also pays a $10 permanent building fund tax (2025 Form 40 instructions: https://tax.idaho.gov/document-mngr/forms_efo00089).
- State estimated tax
- Idaho doesn't require individuals, including the self-employed, to make estimated payments. Voluntary payments can be made any time with Form 51 or Quick Pay. No required installment schedule. To get the automatic six-month filing extension, you must pay at least 80% of current-year tax or 100% of prior-year tax by the April due date (Idaho State Tax Commission, Apr. 6, 2026: https://tax.idaho.gov/pressrelease/need-an-extension-to-file-your-idaho-income-tax-return-5). Form Form 51.
- Idaho worker classification (direction and control)
- Under Idaho law, an independent contractor is free from direction and control over how the work is done. Some Idaho laws also require that contractors run an established business with their own expenses and income.
Federal rules for 2026
Mileage is the big deduction
Business miles are deductible at the IRS standard rate: $0.725 a mile for miles driven January through June 2026 and $0.76 from July 1. Keep a log of each trip; Gigaverse lets you start and stop trips in the app.
App fees and phone
Platform service fees, a business share of your phone and plan, insulated bags and parking or tolls while working are deductible.
Self-employment tax
On top of income tax, self-employed people pay 15.3% on 92.35% of net profit: 12.4% Social Security up to the 2026 wage base of $184,500, plus 2.9% Medicare with no cap. Half of it is deductible.
Quarterly estimated taxes
No one withholds tax from self-employment income, so you generally pay estimates four times a year if you expect to owe $1,000 or more. For 2026 income the federal dates are April 15, June 15 and September 15, 2026, and January 15, 2027. Paying 100% of last year's tax (110% if your AGI was over $150,000) in four equal installments avoids the underpayment penalty.
A worked example
| Mileage deduction | $11,138 |
|---|---|
| Net profit after mileage | $33,863 |
| Self-employment tax | $4,785 |
| Self-employment tax the mileage saves | $1,574 |
Miles split evenly between the two 2026 rates. Federal figures only; the mileage also lowers income tax. Computed from 2026 IRS limits (Notice 2025-67, Rev. Proc. 2025-32) and the SSA wage base.
