Quarterly Taxes for the Self-Employed: A No-Panic Guide

When you work for yourself, no employer withholds taxes from your pay. Instead, the IRS expects estimated taxes four times a year — and missing them can mean penalties plus a brutal surprise in April. It sounds scary; the system is actually simple. (US-focused education, not tax advice.)

What you actually owe

Self-employed income gets hit by two things: income tax and self-employment tax (~15.3% for Social Security and Medicare — the half an employer normally covers for you). A common rule of thumb is to set aside 25–30% of every payment for taxes.

The set-aside system

The trick isn't paying quarterly — it's being ready to.

1. Open a separate "tax" savings account.
2. Every time you get paid, move ~30% into it immediately. Treat it as money that was never yours.
3. Pay your estimate from that account on the four due dates (roughly April, June, September, and January).

Do this and quarterly taxes become a transfer, not a crisis.

Lower the bill, legally

Track business expenses all year — software, equipment, mileage, a home office. Each legitimate deduction lowers your taxable profit. A simple spreadsheet or bookkeeping app pays for itself.

Price so taxes are covered

Here's the part freelancers forget: if you don't price for taxes, you're effectively taking a 30% pay cut. Build the tax bite into your rate from the start — the Rate Calculator sets a floor that accounts for it, so what you keep is what you planned.
