If you drive for Uber or deliver for DoorDash, you already know the money hits your account fast.
What you may not know is that a chunk of it isn't really yours — and the bill comes due in April, often with penalties attached.
Here's the math that catches people off guard.
Employees split payroll taxes with their boss: 7.65% each.
Independent contractors pay both halves — 15.3% — on top of income tax.
On $40,000 of gig earnings, that's roughly $6,100 in self-employment tax alone, before a single dollar of federal income tax is calculated.
Most gig platforms don't withhold anything.
Uber, Lyft, DoorDash, and Instacart generally treat drivers as contractors, which means no taxes are taken out of your weekly payout.
Then tax season arrives and the surprise lands all at once.
There's a legitimate offset, and it's the single most overlooked line on a gig worker's return.
The qualified business income deduction lets many sole proprietors deduct up to 20% of net profit.
You also write off mileage — at 67 cents per mile for 2024 — plus phone bills, phone mounts, insulated bags, and the portion of your rent or utilities used for a home office.
Skipping these is leaving real money on the table.
The IRS doesn't take your word for mileage.
A log or a tracking app like Everlance or Stride is what survives an audit.
And if you made more than $400 net, you owe self-employment tax — no minimum threshold saves you.
The payment schedule is where people get hurt.
Taxes are supposed to be paid quarterly: April, June, September, and January.
Miss those, and the IRS adds an underpayment penalty plus interest, even if you pay in full by April 15.
Gig workers who owed $3,000 last year and ignored it are now staring at a bill closer to $3,300.
There's a policy fight underneath all this.
Some states, including California and New York, have pushed to reclassify gig workers as employees, which would shift half the payroll tax back to the platforms.
Companies have spent heavily fighting that.
Meanwhile, several platforms now offer optional same-day payouts — convenient, but they don't set aside a dime for taxes.
The practical move is boring and effective: open a separate savings account and move 25% to 30% of every payout into it immediately.
Then make quarterly payments through IRS Direct Pay.
My take: the gig model sells flexibility, but a slice of that flexibility is really risk shifting.
The platforms get predictable labor costs and no payroll tax liability.
Final Thoughts
If you're earning on a gig app, treat the tax set-aside as non-negotiable, because the IRS will treat it that way whether you did or not.
