If you drove for Uber, delivered for DoorDash, or sold crafts on Etsy last year, there is a decent chance you owe money this spring instead of getting a refund.
The reason is simple and brutal: nobody withheld taxes from your pay.
Every dollar you earned arrived before the government took its cut, and now it is due all at once.
Traditional employees have taxes pulled from each paycheck automatically.
Gig workers are treated as self-employed, which means they are responsible for both halves of Medicare and Social Security, plus federal and state income tax.
That combined bill can swallow a startling share of what looked like solid earnings.
That is the self-employment tax rate covering Social Security and Medicare, and it applies to your net profit, not your gross.
Add income tax on top, and many gig workers discover they owe 25% to 30% of what they made.
On $20,000 of delivery income, that can mean a bill north of $5,000.
Here is the part that catches people off guard: the IRS expects quarterly payments.
If you owed more than $1,000 last year and did not pay in estimated installments, you may also face an underpayment penalty.
That penalty is not huge, but it is interest piling up on money you never set aside.
You can deduct business expenses, and gig workers routinely leave money on the table by ignoring them.
The IRS standard mileage rate for 2024 was 67 cents per mile, and for 2025 it is 70 cents.
If you drove 12,000 miles delivering food, that is over $8,000 in deductions that could wipe out much of your tax bill.
Other deductions people miss: the portion of your phone bill tied to work, hot bags and insulated gear, parking and tolls, health insurance premiums, and the home office space you use for admin work.
Every documented expense lowers the profit the IRS taxes.
A shoebox of gas receipts beats nothing, but a mileage tracking app beats both.
The deeper problem is that the apps make this invisible.
Your weekly earnings screen shows a clean number, and taxes never appear.
Many workers assume the platform handles it.
Companies like Uber and DoorDash generally do not withhold taxes for independent contractors, and they are not required to.
Some states have started nudging workers with annual statements and educational notices, but there is no national safety net here.
The responsibility lands entirely on you, usually in April, usually with interest.
You can request an installment plan from the IRS, which splits the balance into monthly payments.
You can file even if you cannot pay, because the failure-to-file penalty is far steeper than the failure-to-pay penalty.
And you can start setting aside 25% to 30% of every payout right now to avoid repeating the cycle next year.
The gig economy sells freedom and flexibility.
What it does not sell is a payroll department.
Until that changes, the tax bill is yours to track, yours to calculate, and yours to pay. **The bottom line:** Treating every app payout as pre-tax money is the single habit that separates gig workers who stay ahead from those who get ambushed in April.
Final Thoughts
Set the money aside the moment it lands, track every mile, and the spring surprise shrinks fast.
