Estimate self-employment tax and separate federal + state quarterly payments on 1099 income from Uber, DoorDash, freelancing, and more.

Fields below start filled with example values — edit them to match your own situation, or use "Reset to example" to clear back to the example.
Mileage, supplies, phone bill, home office, etc. Reduces your taxable net profit.
Net profit from any other self-employment activity, already after its own expenses.
Affects your remaining Social Security wage base and Additional Medicare Tax threshold — W-2 withholding alone doesn't cover self-employment tax.
Interest, dividends, or other taxable income — affects your federal bracket.
Made permanent by OBBBA. Applies the lesser of 20% of QBI or 20% of taxable income before QBI, including SSTB phase-out where applicable.
Determines whether your QBI deduction phases out to $0 above the threshold, or hits the (unmodeled) wage/UBIA limitation instead.
Child Tax Credit, education credits, etc. Reduces federal income tax owed directly.
From a W-2 job, if any. Reduces only your federal required payment — never applied against state tax.
