If you drive for a rideshare app, deliver food, or sell handmade goods online, there's a good chance you've been treating your side income like a bonus.
Gig work is self-employment income, and that changes almost everything about how you file.
The biggest surprise for most people is the self-employment tax.
When you work a regular W-2 job, your employer splits your Medicare and Social Security taxes with you.
As a gig worker, you're both the boss and the employee, so you cover the whole bill yourself.
That's 15.3% on your net earnings, on top of whatever regular income tax you owe.
There's another trap: no one is withholding money for you.
Your paycheck from an app is usually the full amount with nothing set aside.
That means the money sitting in your account isn't really all yours.
Come April, a lot of workers discover their tax bill is bigger than their savings cushion.
Set aside a percentage of every payment you receive, ideally in a separate account you don't touch.
Many accountants suggest tucking away somewhere between 25% and 30% of net gig income, though your exact number depends on your total earnings and bracket.
It's easier to save a little every week than to find a lump sum in the spring.
You should also know that not all your income is taxable.
You can deduct ordinary and necessary business expenses, and gig workers often leave real money on the table.
If you drive for work, tracking your miles can knock a meaningful chunk off what you owe.
Phone bills, data plans, delivery bags, and a portion of your home internet can count too.
The IRS wants proof, and a rough guess won't hold up.
Free or low-cost apps can log your mileage automatically, and a simple folder for receipts takes minutes to set up.
If you've been ignoring this, start now rather than trying to reconstruct a year you can't remember.
One more thing worth checking: whether you owe quarterly estimated payments.
If you expect to owe $1,000 or more for the year, the IRS generally wants you paying in four installments rather than one lump sum.
Skipping those payments can trigger penalties, even if you pay everything you owe on time in April.
If your gig income is small or this is your first year, a tax software program may handle it fine.
If you're earning steadily or juggling multiple apps, a session with a tax professional can pay for itself.
They know the deductions people miss and can help you set up a system that stops the yearly scramble.
None of this is meant to scare you off gig work.
It's flexible, and for a lot of people it's the best option available.
But the tax side isn't optional, and the workers who get burned are usually the ones who found out too late.
The real advantage here goes to people who plan ahead.
Ten minutes of setup now beats a stressful week in April, and the money you set aside was never yours to spend anyway.
Final Thoughts
Treat the tax cut like a bill you pay yourself, and the whole thing gets a lot less painful.
