The tax door

Side hustle taxes, in plain words — 2026

Hustle income is taxed whether or not a form ever arrives. This page is the whole beginner picture: what the tax is, when it's due, what your car is worth as a deduction, and the habit that keeps April boring. Education, with IRS sources named — not tax advice, and not a filing service.

The one-sentence version

On top of income tax at your bracket, self-employment tax takes 15.3% of 92.35% of your hustle profit — and it starts at $400 of profit, form or no form (IRS Topic 554).

The four dates (2026 quarterly estimates)

Estimates are generally required if you expect to owe $1,000 or more for the year. Even when they're not required, the set-aside below is what makes filing painless.

Your car is a deduction with a date on it

When you droveIRS standard mileage rateSource
Jan–Jun 202672.5¢ per business mileIRS Notice 2026-10 (IR-2025-128)
Jul–Dec 202676.0¢ per business mileIRS IR-2026-29 (mid-year raise)

The rate is the IRS's full cost of running a car — gas, wear, insurance, depreciation — which is why the Real Pay Checker prices your miles with it instead of with gas money. A mileage log (date, purpose, miles) is what turns driving into this deduction.

The set-aside habit

Move a percentage of every payout into a separate account the day it lands: roughly 26 of every $100 of profit at the 12% bracket, about 34 at 22% — planning figures built from the IRS mechanics above; your real return depends on your deductions and household. Every result on this site computes your set-aside from your own bracket.

The forms, at their real thresholds

  • 1099-NEC — platforms and clients report payments of $2,000 or more (2026 threshold).
  • 1099-K — payment apps report at $20,000 and 200 transactions (2026, federal).
  • Neither form creates the tax. The $400 self-employment threshold is the law whether or not an envelope arrives.
