When you had a W-2 job, taxes came out of every paycheck before you ever saw the money. As a gig driver, nobody does that for you. The full amount hits your bank account, and the tax is still owed. The IRS does not wait until April to collect it. It expects you to pay as you earn, in four installments, and if you skip them you can owe a penalty on top of the tax itself.

Quarterly estimated taxes catch new drivers off guard more than any other part of self-employment. This guide covers who has to pay, how to estimate the amount with a worked example, the 2026 deadlines, and the safe-harbor rule that keeps you out of penalty territory.

The 2026 estimated tax deadlines

Estimated taxes are due four times a year. The "quarters" are not even three-month blocks, which trips people up:

PaymentIncome periodDue date
1stJan 1 – Mar 31April 15, 2026
2ndApr 1 – May 31June 15, 2026
3rdJun 1 – Aug 31September 15, 2026
4thSep 1 – Dec 31January 15, 2027

When a due date falls on a weekend or legal holiday, it moves to the next business day; all four 2026 dates fall on weekdays. One useful exception: you can skip the January payment if you file your 2026 return and pay the full balance by February 1, 2027.

Who has to pay quarterly

You generally owe estimated taxes if you expect to owe at least $1,000 in federal tax for the year after subtracting withholding and credits. For a driver whose income is entirely 1099, with no withholding, that threshold is easy to cross. If gig driving is your main income, assume you owe quarterly estimates unless you have a specific reason to think otherwise.

If you also have a W-2 job, you have another option: increase the withholding on that paycheck to cover your gig income, using a new Form W-4. Withholding is treated as paid evenly across the year, even if you increase it late in the year, which is why many drivers with a day job prefer it to mailing in estimates.

What you are actually paying

Quarterly estimates cover two federal taxes at once, and the second one surprises people:

  • Federal income tax on your taxable profit, at whatever bracket your total income lands in.
  • Self-employment tax of 15.3 percent on about 92 percent of your net earnings. It covers the Social Security and Medicare that an employer would normally split with you; as a contractor you pay both halves.

Because the two stack, each additional dollar of profit costs roughly 23 cents in federal tax in the 12 percent bracket and about 31 cents in the 22 percent bracket, before any state tax. That is why drivers who mentally set aside "some for taxes" often find it was not enough.

A simple set-aside rule

Many drivers move 25 to 30 percent of net earnings into a separate account for taxes. It is a rough, conservative rule rather than a precise calculation, but it keeps the money from being spent and usually covers federal and state tax for drivers without much other income. Your real number depends on your bracket, your state and your deductions.

How to estimate the amount

You do not need perfect precision. You need a reasonable estimate, paid on time:

  1. Start from net, not gross. Subtract your business deductions from your gross earnings. Mileage is usually the largest; at the 2026 rates of 72.5¢ and 76¢, it can cut your taxable profit by a third or more.
  2. Figure self-employment tax. Multiply net profit by 92.35 percent, then by 15.3 percent.
  3. Figure income tax. Subtract half your self-employment tax, the standard deduction ($16,100 for single filers in 2026) and the 20 percent qualified business income deduction, then apply your bracket to what is left.
  4. Add state tax if your state has an income tax, and check its own estimated-payment rules.
  5. Divide by four for each payment, or pay what you earned each period if your income is uneven.

A worked example

Here is a single driver with no other income who grosses $50,000 in 2026 and drives 25,000 business miles:

LineAmount
Gross earnings$50,000
Mileage deduction (25,000 miles)−$18,560
Phone, supplies and other expenses−$1,440
Net profit$30,000
Self-employment tax$4,239
Federal income tax (after standard and QBI deductions)$942
Total federal tax for the year$5,181
Each quarterly paymentabout $1,300

That works out to about 17 percent of net profit, well under the 25 to 30 percent rule, because this driver has no other income and the standard deduction absorbs much of the income tax. The same driver with a full-time W-2 job would owe much more on the gig profit, since it would be taxed at a higher bracket. Without the mileage deduction, this driver's federal tax would be roughly $4,200 higher. Run your own numbers in the gig driver tax calculator.

How to pay

  • IRS Direct Pay. Free, online, straight from your bank account; the most common route for gig drivers.
  • Your IRS Online Account. Lets you pay and see a record of the payments you have already made.
  • EFTPS. The Electronic Federal Tax Payment System, which lets you schedule payments in advance.
  • Form 1040-ES. The traditional voucher method, with a worksheet for estimating the amount. You can mail it or use the worksheet and pay online.

Keep a record of each payment. Your four estimated payments are credited against your final bill when you file Schedule C and your annual return.

The safe-harbor rule that protects you

You do not have to predict your tax perfectly to avoid a penalty. You generally will not owe an underpayment penalty if your four payments add up to at least the smaller of:

  • 90 percent of this year's tax, or
  • 100 percent of last year's total tax — 110 percent if last year's adjusted gross income was over $150,000.

For most drivers, the easiest path is to take last year's total tax, divide by four, and pay that each quarter. You stay inside the safe harbor even if you earn more this year; you simply settle the rest when you file.

If your income is uneven

Driving income swings with seasons and surges. If you earned most of your money late in the year, the annualized income installment method (Form 2210, Schedule AI) lets you match your payments to when you actually earned the money, which can reduce or eliminate a penalty for smaller early payments.

What happens if you miss a payment

Missing a payment is not a catastrophe, but it is not free. The underpayment penalty works like interest on the amount you should have paid, calculated from the due date until you pay. The fix is to pay as soon as you can rather than waiting for the next deadline. Paying late still beats paying nothing until April.

Get your numbers checked

Estimated taxes depend on your full financial picture, including other income, a spouse's earnings, credits and your state's rules, none of which a general guide can see. Use this as a framework, then confirm your quarterly amount with a qualified CPA or enrolled agent, especially in your first year of gig work.

Frequently asked questions

Do gig drivers have to pay quarterly taxes?

Generally yes, if you expect to owe at least $1,000 in federal tax for the year after withholding and credits. Most full-time 1099 drivers cross that threshold. Drivers with a W-2 job can sometimes cover it by increasing withholding instead.

When are 2026 quarterly estimated taxes due?

For tax year 2026, estimated payments are due April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027.

How much should a gig driver set aside for taxes?

Many drivers set aside 25 to 30 percent of net earnings, which usually covers federal income tax, the 15.3 percent self-employment tax and some state tax. A driver with no other income often owes less; one with a W-2 job or high earnings may owe more.

How do I avoid the underpayment penalty?

Pay at least the smaller of 90 percent of this year's tax or 100 percent of last year's tax (110 percent if last year's adjusted gross income was over $150,000), spread across the four due dates. Paying a quarter of last year's total tax each quarter is the simplest way to stay in the safe harbor.

The bottom line

Nobody withholds tax from your gig income, so the IRS asks you to pay it in four installments. Set money aside as you go, estimate from net profit after your mileage deduction, pay by each deadline through IRS Direct Pay, and lean on the safe harbor to stay penalty-free. Handled steadily, quarterly taxes go from the scariest part of driving to a routine transfer four times a year. And because every tracked mile lowers what you owe, a complete mileage log makes each payment smaller.
