If you drive for Uber, deliver for DoorDash, or rent out a spare room on Airbnb, there's a good chance the money you owe Uncle Sam is quietly piling up faster than you think.
And a fresh set of IRS rules is about to make this tax season sting a little more for people who earn money on the side.
A rule that was supposed to kick in a few years ago—then got delayed—is now fully in effect for the 2025 tax year.
Payment apps and gig platforms have to send you a Form 1099-K once you clear $2,500 in business payments, down from the old $20,000 threshold.
That means a lot of casual sellers and side hustlers who never got one of these forms before will find one in their inbox this year.
Because many gig workers assume that if no form shows up, the IRS doesn't know about the money.
Now there's a paper trail, and if your reported income doesn't match it, expect a letter.
The bigger trap is the self-employment tax.
Employees split Medicare and Social Security taxes with their boss, each paying 7.65%.
Gig workers pay both halves—15.3%—on top of regular income tax.
On $30,000 of gig earnings, that's roughly $4,590 before you even get to federal and state income taxes.
That number surprises almost everyone the first time.
You can deduct business expenses like mileage, phone bills, home office space, and supplies.
The standard mileage rate for 2024 was 67 cents per mile, and tracking those miles can wipe out a big chunk of what you owe.
Drivers who skip this are essentially donating money to the IRS.
You may also owe quarterly estimated taxes.
If you expect to owe $1,000 or more for the year, the IRS wants payments in April, June, September, and January.
Miss them and you can get hit with an underpayment penalty—even if you pay everything in full by April 15.
One more thing worth knowing: gig platforms don't withhold taxes for you.
That paycheck hitting your account is the full amount, which makes it easy to spend money that isn't really yours.
Setting aside 25% to 30% of every payment into a separate account is the simplest way to avoid a springtime shock.
If this is your first year dealing with it, free filing options exist.
The IRS Free File program and Direct File cover some self-employed filers, and many tax software companies offer free tiers for simple returns.
Just check the income limits before you start, because self-employment schedules can push you out of the free versions fast.
Treat every gig payment like it's already been taxed, track your expenses, and don't wait until April to do the math.
The gig economy sold us on freedom and flexibility, but it quietly outsourced the boring parts—bookkeeping, withholding, quarterly payments—to us.
The workers who thrive aren't the ones earning the most.
They're the ones who set aside a little each week and keep a running log of every mile.
Final Thoughts
Do that, and tax season becomes a chore instead of a crisis.
