Every number in our calculator is based on published IRS formulas and official state tax rates. This page explains exactly how we arrive at each figure — so you can verify our math.
Self-employment tax covers Social Security (12.4%) and Medicare (2.9%) — the same taxes W-2 employees split with their employer. As a gig worker, you pay both halves: 15.3% total. The IRS allows a small adjustment before applying the rate.
Federal income tax is calculated on adjusted gross income (AGI), which is net profit minus the SE deduction (half of SE tax). We apply the standard deduction before estimating the bracket.
| Rate | Single filer taxable income | Married filing jointly |
|---|---|---|
| 10% | $0 – $11,925 | $0 – $23,850 |
| 12% | $11,926 – $48,475 | $23,851 – $96,950 |
| 22% | $48,476 – $103,350 | $96,951 – $206,700 |
| 24% | $103,351 – $197,300 | $206,701 – $394,600 |
| 32% | $197,301 – $250,525 | $394,601 – $501,050 |
| 35% | $250,526 – $626,350 | $501,051 – $751,600 |
| 37% | Over $626,350 | Over $751,600 |
Note: Our calculator uses a simplified effective rate based on the most common bracket for the entered income level. Actual federal tax depends on additional deductions, credits, and other income.
We include state income tax for all 50 states + DC (50 states + D.C.). Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Gig workers who expect to owe $1,000 or more must pay estimated taxes quarterly. We divide the total annual tax estimate by 4 for equal quarterly payments.
