Rideshare drivers, delivery couriers and freelancers don’t have taxes taken out of their app pay, so tax season is often a surprise. This tax refund estimator for gig workers uses the 2026 IRS numbers to show whether you’re on track for a refund or a bill in April. It covers your mileage deduction, self-employment tax, the new no-tax-on-tips deduction and what you’ve already paid. It also tells you how much to send by January 15 to avoid an underpayment penalty.

- No one withholds for you. Apps don’t take out taxes, so unless you sent quarterly payments, the whole bill lands at filing time.
- Self-employment tax is the big one. 15.3% of most of your profit goes to Social Security and Medicare, on top of income tax, even when your income tax is low.
- Mileage is your biggest lever. Every 1,000 business miles you log cuts profit by about $740, which lowers both taxes.
- Jan 15 is the last 2026 estimated payment. Paying what you can by then shrinks or avoids the underpayment penalty.
Put your numbers to work
Estimate for planning only, not tax advice; consult a CPA for your situation. Uses 2026 federal figures: brackets and standard deduction, self-employment tax at 15.3% on 92.35% of profit (Social Security part capped at $184,500, reduced by W-2 wages unless filing jointly), the 20% QBI deduction for a sole proprietor with no employees, the no-tax-on-tips deduction, and the $2,200 child tax credit ($1,700 refundable). Mileage uses 74.25¢, the average of the two 2026 rates. Leaves out the earned income credit, education and other credits, the 0.9% additional Medicare tax, other deductions and state tax. Penalty check uses the IRS safe harbors (owe under $1,000, or pay 90% of this year’s tax or 100% of last year’s, 110% if income is over $150,000). See all calculators.

Gig worker tax refunds: common questions
Do gig workers get a tax refund?
Sometimes. Uber, DoorDash and Instacart don't withhold taxes, so most full-time gig workers owe at filing unless they made quarterly payments. You can get a refund if you also have a W-2 job with withholding, overpaid your estimates, or qualify for refundable credits like the child tax credit. The estimator above shows which way you're headed.
How much will I owe in taxes on $40,000 of gig income?
It depends mostly on your expenses. With about 15,000 business miles, a single filer with no other income would have roughly $29,000 of profit and owe around $4,000 to $5,000 in total federal tax, most of it self-employment tax. Enter your own miles and payments above for your number.
Can I still avoid the underpayment penalty for 2026?
Often, yes. If you'll owe $1,000 or more, pay enough by January 15, 2027 to reach 90% of your 2026 tax or 100% of your 2025 tax (110% at higher incomes). Payments made earlier in the year count more, so a January payment may not erase the whole penalty, but it limits it.
