Millions of Americans who drive for rideshare apps, deliver food, or sell crafts online are discovering that the money they set aside last year doesn't cover what they owe.
The reason is a tax structure built for traditional employees, not for people juggling three apps and a car payment.
When you work for an employer, payroll taxes get withheld automatically.
When you're a gig worker, nobody withholds anything.
You're responsible for both the employee and employer halves of Social Security and Medicare, which adds up to 15.3% of your net earnings right off the top.
A driver who earned $40,000 in gross receipts might net far less after mileage, phone bills, and platform fees — but the tax bill is calculated on profit, and many workers never tracked those expenses closely enough to claim them.
The mileage deduction is the single biggest lever most drivers have.
The IRS standard rate for 2024 was 67 cents per mile, and for 2025 it's 70 cents.
If you drove 20,000 miles, that's a $14,000 deduction.
Skip the log, and you're handing that money to the government instead.
Many apps pay a base rate plus tips, and the tips are taxable.
Some platforms issue a 1099-K or 1099-NEC, but others don't, which leads workers to assume the income doesn't count.
The IRS gets a copy of every 1099 filed, and matching notices are increasingly automated.
Renters and homeowners who gig on the side are also feeling it.
If you rent out a spare room through a short-term rental app for more than 14 days a year, that income is generally taxable.
A lot of hosts didn't realize the 14-day rule only applies if you also live in the home.
Credit card debt is making the squeeze worse.
Many gig workers cover gas, maintenance, and supplies on personal cards, then carry a balance when a big repair hits.
At current average rates above 20%, a $3,000 balance can cost $600 a year in interest alone — money that could have gone to quarterly estimated taxes.
The fix isn't complicated, but it has to start early.
Set aside 25% to 30% of every payout in a separate account.
Save receipts for phone mounts, insulated bags, and car washes.
And if you owe more than $1,000 for the year, the IRS expects quarterly payments, not one lump sum in April.
Penalties for underpayment aren't huge, but they compound.
The IRS charges interest on the unpaid amount, and the rate moves with the federal funds rate.
With rates still elevated compared to a few years ago, that penalty stings more than it used to.
Some states with no income tax, like Texas and Florida, won't touch your gig earnings.
Others, like California and New York, will.
A driver in Sacramento can owe thousands more than one in Austin on the same income.
The bigger issue is that the system assumes a stability most gig workers don't have.
Income swings week to week, and a slow January can wreck a budget built in October.
Setting aside a percentage rather than a fixed dollar amount helps smooth that out.
An IRS payment plan is available online, and penalties can sometimes be reduced if you ask.
Filing an extension gives you until October to file, but not to pay. **Our take:** The gig economy sold flexibility, but it quietly shifted the tax burden onto workers who were never trained to handle it.
If you earn money through an app, treat a quarter of every deposit as money you don't own.
Final Thoughts
The people who do this from day one are the ones who aren't panicking in April.
