BureauzillaHow Do US Freelancers Pay Quarterly Estimated Taxes?
1040-ES due dates, the $1,000 threshold, safe harbor, and a case habit that keeps quarters from slipping.
W-2 jobs withhold. Freelancer income usually does not. The IRS still wants pay-as-you-go. That is what estimated tax is for: income tax plus self-employment tax, spread across four payment periods.
When you generally must pay
Per the IRS estimated taxes page, if you expect to owe at least $1,000 after withholding and credits, you generally need estimated payments. Sole proprietors, partners, and S corporation shareholders typically figure them with Form 1040-ES.
Underpayment by a period due date can trigger a penalty even if you later get a refund when you file.
2026 payment due dates
From the 2026 Form 1040-ES package:
| Income period | Due date | | --- | --- | | Jan 1 – Mar 31 | April 15, 2026 | | Apr 1 – May 31 | June 15, 2026 | | Jun 1 – Aug 31 | September 15, 2026 | | Sep 1 – Dec 31 | January 15, 2027 |
If a due date falls on a weekend or legal holiday, the next business day counts. You can skip the January 15 payment if you file the prior-year return and pay the full balance by the early-February date printed in that year’s 1040-ES instructions.
How much to send
Common approaches (details in Publication 505 and the 1040-ES worksheet):
- Pay enough so you hit safe harbor: generally 100% of last year’s total tax (110% if prior-year AGI was over $150,000), or
- Aim for 90% of this year’s tax, paid across the periods.
Self-employment tax sits inside the estimate. The 1040-ES worksheets walk through Schedule C-style net earnings and the SE deduction. Recalculate mid-year if income spikes or dies.
A freelancer habit that sticks
- Open a dedicated tax savings pocket. Move a percentage of every client payment the day it clears.
- Put all four due dates on a calendar the week you file last year’s return.
- Pay via IRS Direct Pay or EFTPS and save the confirmation number next to the case for that quarter.
- If your state has estimated tax, calendar those dates too. Federal and state are separate piles.
Bureauzilla treats each quarter as a case with a deadline and a payment receipt attachment. The product reminds. You stamp the pay.
