Quarterly Estimated Taxes for Gig Drivers: Due Dates and What to Keep

If you drive or deliver as an independent contractor, the platform usually does not withhold income tax the way a paycheck does. The IRS expects that tax to be paid during the year, either through quarterly estimated payments or through extra withholding from a separate W-2 job. Missing the due dates can lead to an underpayment penalty even if you later get a refund.

This article summarizes published IRS rules for individual estimated tax. It is not tax advice, and it is not a calculation of what you owe. Use Form 1040-ES, Publication 505, and the IRS page on managing taxes for gig work, or talk with a tax professional about your own facts.

When a return is required, and when estimated tax may be required

The IRS says you must file a tax return if you have net earnings from self-employment of $400 or more from gig work, even if the work is a side job, part-time, or temporary. You must report the income even if you never receive a Form 1099.

Estimated tax is a separate question from filing. In most cases, you must pay estimated tax for 2026 if both of the following apply:

1. You expect to owe at least $1,000 in tax for 2026 after subtracting withholding and refundable credits.
2. You expect your withholding and refundable credits to be less than the smaller of 90% of the tax on your 2026 return, or 100% of the tax shown on your 2025 return (your 2025 return must cover all 12 months).

If your 2025 adjusted gross income was more than $150,000, or more than $75,000 if your 2026 filing status is married filing separately, the prior-year figure is 110% instead of 100%. Form 1040-ES and Publication 505 also describe special rules for farming and fishing income and for certain other situations.

You do not have to pay estimated tax for 2026 if you were a U.S. citizen or resident alien for all of 2025 and you had no tax liability for that full 12-month year. If you also have a job with withholding, you may be able to cover the tax on your gig income by having more tax taken out of that paycheck. The IRS points people to the Tax Withholding Estimator and a new Form W-4 given to the employer.

The four payment periods and due dates

For estimated tax, the year is split into four payment periods. For 2026, Form 1040-ES lists these due dates:

• April 15, 2026, for January 1 through March 31
• June 15, 2026, for April 1 through May 31
• September 15, 2026, for June 1 through August 31
• January 15, 2027, for September 1 through December 31

If a due date falls on a Saturday, Sunday, or legal holiday, the payment is on time if you make it on the next day that is not a weekend or legal holiday. You can pay the full year's estimated tax by the first due date, or in four amounts. You do not have to make the January 15, 2027 payment if you file your 2026 tax return by February 1, 2027, and pay the entire balance due with that return.

The second period is only two months long, and the fourth period runs through the end of the calendar year but is due in mid-January. If your mileage and income swing from month to month, those uneven windows matter when you estimate a payment.

What the payments are meant to cover

Estimated tax is how you pay tax on income that is not subject to withholding, including self-employment earnings from gig work. For many drivers that includes federal income tax and self-employment tax, which covers Social Security and Medicare and is figured on Schedule SE when you file. You figure the year's estimate on Form 1040-ES. If your income is uneven, Publication 505 describes an annualized installment method. Pay online, by phone, or by mail, following Form 1040-ES and the IRS payments page.

Records worth keeping all year

The IRS tells gig workers to keep records of income and receipts during the year, and to report all income even when a platform does not send a form. By January 31 you may receive copies of forms also sent to the IRS, such as Form 1099-K, Form 1099-NEC, Form 1099-MISC, or Form W-2 if some work was treated as employment. Your own log should still include payments that never appear on a 1099, along with vehicle expenses, receipts, and mileage for the same date ranges as the estimated-tax periods.

Gig Driver is built for that kind of log. You can record income by platform, attach receipt photos to expenses, log trip or shift miles, and keep those records split by vehicle if you use more than one car. The dashboard can show income, expenses, profit, and mileage by week, month, year, or a custom range, which is useful when you are looking at a quarter rather than a single shift. When you need a copy for bookkeeping or to share, you can export CSV files and PDF reports. The app does not file your taxes or tell you what to pay.

For expense and car-cost rules, the IRS points to Publication 463 and Publication 535. For the return itself, independent contractors commonly file Form 1040 with Schedule C and Schedule SE. Those publications and forms are the official source for what you may deduct and how you report the year.

A simple quarterly checklist

Use this as a recordkeeping checklist, then do the actual tax math with Form 1040-ES or a preparer:

1. Before each due date, total income and expenses for that payment period from your own log, not from memory.
2. Compare the period to the rest of the year so far, because a single busy month can throw off a four-equal-payment plan.
3. Make the payment on time, or confirm that extra W-2 withholding is already covering the need.
4. Save the payment confirmation with the same records you will use to file.

The January 15, 2027 date is the next one on the 2026 calendar after September 15. If you have not been keeping a complete log, start now for the September through December period rather than waiting until a 1099 arrives in January. Keep income, receipts, and mileage in one place through the year, then use the IRS worksheet to decide what to send.
