Money & Taxes

Side Gig Tax Calculator

Made money on DoorDash, Etsy, Venmo, Uber, Fiverr, or freelancing? Nobody withheld taxes for you — and the IRS still wants its cut. Here's what you owe.

The Part Nobody Tells You
When you have a regular W-2 job, your employer withholds taxes and pays half of your Social Security + Medicare (FICA). When you freelance or gig work, you pay BOTH halves — that's an extra 7.65% on top of your income tax that W-2 workers never see. It's called the self-employment tax, and it's 15.3% of your net profit. Most first-time gig workers don't find out until they file their taxes and get hit with a bill they weren't expecting.

// Deductions You Can Claim

These reduce your taxable profit. If you spent money to earn money, it's probably deductible. Check the ones that apply — this is NOT exhaustive, just the common ones for gig workers.

The Record-Keeping Rule
You can only deduct what you can prove. Save every receipt. Use a spreadsheet, a notes app, or a free tool like Wave or Hurdlr. The IRS doesn't just take your word for it — if you get audited, you need records. A good habit: take a photo of every business receipt immediately and dump it in a folder. Takes 5 seconds, saves thousands.
// 1099 vs. W-2 — Why It Matters
W-2 (employee): Your employer withholds federal/state taxes, pays half your FICA (7.65%), provides benefits, and handles payroll. You get a W-2 form in January.

1099-NEC (independent contractor): Nobody withholds anything. You're responsible for ALL taxes — income tax + self-employment tax (15.3%). No benefits. You get a 1099 form if you earned $600+ from a single client. Even if you don't get a 1099, you still owe tax on the income.

1099-K (payment platforms): Starting in 2024, platforms like Venmo, PayPal, Etsy, and Uber send a 1099-K if you received $5,000+ in payments. This doesn't mean you owe tax on all of it — only the profit after expenses.

Key point: Getting paid through Venmo, Cash App, or Zelle doesn't make the income invisible. The IRS is actively tracking payment platform transactions. Report everything.
// Quarterly Estimated Payments
Why You Can't Just Pay Once a Year
The U.S. tax system is pay-as-you-go. W-2 employees pay every paycheck through withholding. Self-employed people must pay quarterly estimated taxes using Form 1040-ES. If you owe $1,000+ in taxes and don't pay quarterly, the IRS charges a penalty.

Who needs to pay quarterly: Generally, if you expect to owe $1,000+ in tax for the year after subtracting withholding and credits. If your side gig income is under $5,000 and you have a W-2 job covering most of your tax, you might not need to — but it's safer to pay anyway.

How to pay: Go to irs.gov/payments and use IRS Direct Pay (free, linked to your bank account) or pay by card. You can also mail a check with Form 1040-ES.
