The first freelance tax bill is almost always bigger than expected, and the reason is a tax most employees never see.
Why 1099 income is taxed harder
As an employee, Social Security and Medicare are split. You pay 7.65%; your employer pays 7.65%. You only ever see your half.
Self-employed, you are both. That is 15.3% — 12.4% Social Security up to the annual wage base, 2.9% Medicare with no cap — and it applies before income tax.
So a freelancer in the 22% bracket is not paying 22%. Roughly:
- 15.3% self-employment tax
- 22% federal income tax
- plus state income tax where applicable
A useful rule of thumb: set aside 25–30% of every payment the day it arrives. Higher earners and high-tax states, more.
Quarterly estimated payments
The IRS expects tax as income is earned, not in a lump in April. If you will owe $1,000 or more, you generally must pay quarterly.
The due dates are not even quarters, which trips people up:
| Period earned | Payment due |
|---|---|
| Jan 1 – Mar 31 | April 15 |
| Apr 1 – May 31 | June 15 |
| Jun 1 – Aug 31 | September 15 |
| Sep 1 – Dec 31 | January 15 (following year) |
Pay through IRS Direct Pay or EFTPS. Both are free. Most states with income tax have their own parallel system and their own deadlines.
The safe harbor rule
This is the most useful thing in this article.
You avoid the underpayment penalty if you pay, through withholding and estimates, either:
- 90% of the current year’s tax, or
- 100% of last year’s total tax — 110% if your prior-year AGI was above $150,000
The second option is the gift. You do not have to predict a volatile freelance year. Take last year’s total tax, divide by four, pay that each quarter. Even if you triple your income, no penalty — you settle the difference in April.
For anyone whose income swings, this is the approach.
What you can deduct
Ordinary and necessary business expenses:
- Home office — the simplified method is $5 per square foot up to 300 sq ft
- Health insurance premiums (see our guide on health insurance when self-employed)
- Half of your self-employment tax
- Retirement contributions to a SEP IRA or Solo 401(k)
- Equipment, software, subscriptions
- Business mileage at the standard IRS rate
- Professional fees, including your accountant
- Business portion of phone and internet
The QBI deduction (Section 199A) allows many self-employed people to deduct up to 20% of qualified business income, subject to income thresholds and business-type limits. It is significant and frequently missed.
The first-year trap
Your first freelance year often produces no quarterly payments — you did not know, or you had no prior year to base them on.
Then in April you owe self-employment tax and income tax on a full year at once, and your first quarterly payment for the new year is due the same day.
Plan for it. If you went freelance this year, the money you set aside needs to cover roughly five quarters of tax next April, not four.
What to actually do
- Open a separate savings account. Move 25–30% of every payment into it the day it lands. Do not treat that balance as yours.
- Look up last year’s total tax (Form 1040, total tax line). Divide by four. That is your safe harbor payment.
- Put the four dates in your calendar now, with a reminder a week before.
- Track deductions as you go. Reconstructing a year in April is how deductions get missed.
- Get an accountant in year one. A few hundred dollars that routinely saves multiples of that, and they set the structure up correctly from the start.
This explains how the system works; it is not tax advice. Rates, thresholds and rules change annually — confirm your own position with a qualified tax professional.
