All figures for tax year 2024. Estimates only.
Stash roughly this share of every gig payout into a tax savings account.
Educational estimate — not tax advice. Consult a CPA for filing.
Generic tax calculators were built for W-2 employees. We built this from the SE tax form up.
Combine Uber, DoorDash, Instacart and 1099 freelance income in one calc — most tools force one-at-a-time.
92.35% net earnings × 15.3%, plus the deductible half — done right, not hand-waved.
Federal brackets + your state's effective rate. Zero-tax states (FL, TX, WA…) handled correctly.
We compute your Q1–Q4 estimated payment so you stop getting underpayment penalties.
The number that actually matters: what % of every payout to stash for taxes.

It uses 2024 federal brackets, the IRS standard mileage rate ($0.67/mi), and a 15.3% self-employment tax with the 92.35% adjustment and ½ SE deduction. State tax is a flat-rate estimate of each state's effective burden. It's a strong planning estimate — not a substitute for filing software or a CPA.
Yes. As a 1099 contractor you pay both the employer and employee halves of Social Security and Medicare. That's why W-2 calculators dramatically underestimate what gig workers owe.
The IRS expects estimated payments four times a year if you'll owe $1,000+. We compute a per-quarter number you can pay via IRS Direct Pay.
