When are quarterly taxes due?
Federal estimated taxes are generally due April 15, June 15, September 15, and January 15. Missing them can trigger IRS underpayment penalties, even if you pay in full by April.
How much should I set aside for taxes as a 1099 worker?
Many gig workers set aside 25–30% of net income, but it depends on your bracket, deductions, and other income. This calculator gives a more tailored estimate from your numbers, it’s still an estimate, not advice.
Does this include self-employment tax?
Yes. The estimate combines federal income tax (after the standard deduction and the deductible half of SE tax) with the 15.3% self-employment tax, then splits the total into four payments.
What are the 2026 quarterly estimated tax due dates?
For 2026 income: April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. When a date falls on a weekend or legal holiday, the deadline moves to the next business day.
Do I have to pay quarterly taxes if I'm a gig worker?
Generally yes, if you expect to owe $1,000 or more in federal tax for the year after withholding and credits. Most DoorDash, Uber, Instacart and freelance workers have no tax withheld, so they usually cross that line.
What is the safe harbor for estimated taxes?
You generally avoid the underpayment penalty if your payments cover at least 90% of this year's tax or 100% of last year's tax (110% if last year's adjusted gross income was over $150,000). Paying four equal installments based on last year's total is the simplest way to stay safe.
How do I pay quarterly taxes to the IRS?
Online through IRS Direct Pay or your IRS online account (free, from a bank account), through EFTPS, or by mailing a check with a Form 1040-ES voucher. Many states also require their own estimated payments.
What happens if I miss a quarterly payment?
The IRS charges an underpayment penalty, which works like interest on the amount that was late, for each quarter you underpaid. Paying as soon as you can reduces it. It is not a reason to skip the remaining quarters.
Can my mileage lower my quarterly taxes?
Yes. Business miles reduce your net self-employment income, which lowers both income tax and self-employment tax. Logging every trip is one of the biggest levers a driver has. The Gigaverse app logs trips and keeps your quarterly estimate updated as you earn.
