Quarterly Taxes for Side Hustlers: What You Need to Know

If you're making money outside of a regular W-2 job, the IRS expects you to pay taxes on that income four times a year. Not once in April. Four times. And if you don't, they'll charge you penalties and interest.

Who needs to pay quarterly taxes?

If you expect to owe $1,000 or more in taxes from your self-employment income, you're supposed to make estimated quarterly payments. This applies to freelancers, gig workers, contractors, Etsy sellers, Uber drivers, and anyone else earning money that doesn't have taxes withheld automatically.

The self-employment tax nobody warns you about

When you're employed, your employer pays half of your Social Security and Medicare taxes. When you're self-employed, you pay both halves. That's 15.3% right off the top (12.4% Social Security + 2.9% Medicare) before you even get to income tax.

The good news: you can deduct half of your self-employment tax from your taxable income. This calculator accounts for that.

Deductions matter more than you think

Every legitimate business expense you track is money you don't pay taxes on. Common deductions for side hustlers include:

Software and tools you use for work
Home office space (simplified method: $5/sq ft, up to 300 sq ft)
Equipment (computer, camera, microphone)
Internet and phone (business percentage)
Professional development and courses
Business insurance
Mileage for business driving

When are quarterly payments due?

The IRS quarterly schedule isn't actually quarterly. It's a little weird:

Q1 (Jan-Mar): Due April 15
Q2 (Apr-May): Due June 15
Q3 (Jun-Aug): Due September 15
Q4 (Sep-Dec): Due January 15 of the next year

Use IRS Form 1040-ES to make payments. You can pay online at irs.gov/payments.

What happens if you don't pay?

The IRS charges an underpayment penalty. It's not devastating (currently around 7-8% annually on the underpaid amount), but it adds up. If you're going to be late, file anyway. The failure-to-file penalty is much worse than the failure-to-pay penalty.
