Quarterly estimated taxes for gig drivers in 2026

Why quarterly, not just in April

The U.S. tax system is pay-as-you-go. Employees get this handled automatically through withholding; independent contractors don't have an employer doing it, so the IRS asks you to estimate and pay it yourself, four times a year, roughly matching when you earned the income.

Skip it and settle up in April, and you can owe both the tax and an underpayment penalty — interest, essentially, charged from each due date you missed. The penalty exists independent of whether you paid the full amount eventually.

The safe harbor: how to know if you actually owe a penalty

Per the IRS's own estimated-tax guidance, most taxpayers avoid the underpayment penalty if either is true:

• You owe less than $1,000 in tax after subtracting withholding and credits, or
• You paid at least 90% of this year's tax, or 100% of last year's tax (110% if your prior-year adjusted gross income was over $150,000) — whichever of those two is the smaller number.

That second rule is the one that actually matters for most drivers: if last year was a normal year, paying in four installments that add up to last year's total tax bill is enough to be safe, even if this year turns out to owe more. You true up the difference in April with no penalty.

The four 2026 dates, and what each one covers

Notice the periods aren't even quarters — Q2 is two months, Q3 is three. That's the IRS's schedule, not a typo. Dates can shift a day or two if the 15th lands on a weekend or federal holiday; the exact date for each payment is worth a quick check on Form 1040-ES close to when it's due.

How your mileage deduction changes the number

Estimated tax is based on net self-employment income — gross earnings minus deductible business expenses, mileage included. The 2026 split rate applies here too: 72.5¢ per business mile through June 30, 76¢ from July 1. A driver who logs miles carefully going into a quarter's estimate has a real, lower number to work from; a driver who guesses tends to guess conservatively low on the deduction, which means overpaying the estimate. See the calculator for your own figure, and what a log actually needs to hold up.

Self-employment tax — 15.3% on 92.35% of net earnings, per the IRS's own explanation — is due alongside income tax in the same estimated payments. It's easy to forget because nothing labeled "self-employment tax" shows up on a 1099; it's calculated on Schedule SE and folded into the same number.

A simple way to estimate what to send

1. Add up gross earnings so far this year, across every platform.
2. Subtract deductible expenses: mileage (at the correct rate for each date), phone, supplies, and anything else that's genuinely business use.
3. That's roughly your net self-employment income. Multiply by about 25–30% as a rough all-in rate (self-employment tax plus a moderate income tax bracket) to get a ballpark payment — this is a rough planning number, not a substitute for the Form 1040-ES worksheet or a tax professional's number.
4. Pay through IRS Direct Pay or the Electronic Federal Tax Payment System — both let you schedule the payment and keep a record.
