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.
