How gig taxes work in 2026
As an independent contractor you pay two federal taxes on your profit. Self-employment tax is 15.3% (Social Security + Medicare) applied to 92.35% of your net profit — it applies once profit hits $400 for the year. Income tax is layered on top at your bracket, after deducting half your SE tax. State income tax may apply too; this tool estimates federal only.
If you expect to owe $1,000+, the IRS wants estimated payments through the year — the 2026 due dates are April 15, June 15, September 15, and January 15, 2027. Pay online at IRS Direct Pay; underpayment can mean penalties.
Lower the bill before you pay it
Your biggest lever is the mileage deduction — 72.5¢ per business mile in 2026 comes straight off this calculator's "profit" input. Track every mile first, then estimate taxes on what's left. And check your true hourly pay to make sure the work is worth it after taxes.
FAQ

April 15, June 15, September 15, 2026, and January 15, 2027.
How much should I set aside?
25–30% of net profit is the common rule of thumb — this calculator gives you a sharper number for your bracket.
What if I also have a W-2 job?
You can increase W-2 withholding instead of paying quarterly. Your W-2 income may also push your gig profit into a higher bracket — pick that bracket above.
