When you work for yourself, nobody withholds tax from your pay. The IRS still expects to be paid during the year, not just in April, so most freelancers send estimated tax payments four times a year. Miss them and you can owe a penalty even if you pay everything when you file. Here is what you need for the 2026 tax year.
2026 estimated tax due dates
| Payment | Covers income earned | Due date |
|---|---|---|
| 1st | Jan 1 – Mar 31, 2026 | April 15, 2026 |
| 2nd | Apr 1 – May 31, 2026 | June 15, 2026 |
| 3rd | Jun 1 – Aug 31, 2026 | September 15, 2026 |
| 4th | Sep 1 – Dec 31, 2026 | January 15, 2027 (next one due) |
Two details from the IRS instructions are worth knowing. If a due date lands on a weekend or legal holiday, paying on the next business day counts as on time. And you can skip the January 15, 2027 payment if you file your 2026 return by February 1, 2027 and pay the full balance with it.
Do you have to pay estimated tax?
Per the 2026 Form 1040-ES, you generally must make estimated payments if both of these are true:
- You expect to owe at least $1,000 in federal tax for 2026 after withholding and refundable credits, and
- Your withholding and refundable credits will be less than the smaller of 90% of your 2026 tax or 100% of the tax shown on your 2025 return (which must cover all 12 months).
Separately, you owe self-employment tax once your net earnings from self-employment reach $400 for the year, according to the IRS self-employment tax page. If you also have a W-2 job, you can cover some or all of your freelance tax by raising withholding on a new Form W-4 instead of sending quarterly payments.
The safe-harbor rule: the easiest way to avoid a penalty
You don't have to predict your income perfectly. You generally avoid the underpayment penalty if your payments, made on time across the four dates, add up to at least the smaller of:
- 90% of your 2026 tax, or
- 100% of your 2025 tax, or 110% if your 2025 adjusted gross income was over $150,000 ($75,000 if married filing separately).
For a freelancer whose income is growing, the prior-year option is the simplest: take last year's total tax (plus 10% if you're over the AGI line), divide by four, and pay that on each date. You'll settle any remaining balance in April. If your income is lumpy, for example most of it arrives in the fourth quarter, the IRS's annualized income installment method (Form 2210, Schedule AI) can lower the earlier payments.
How to estimate what you owe
Your estimated tax is two pieces: self-employment tax (Social Security and Medicare) plus income tax.
Self-employment tax
The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It applies to 92.35% of your net profit, not the full amount. For 2026, the Social Security part stops once your combined wages and self-employment earnings reach $184,500; the Medicare part has no cap. An additional 0.9% Medicare tax applies above $200,000 (single), $250,000 (married filing jointly) or $125,000 (married filing separately).
Example: you expect $60,000 of net profit in 2026 and have no W-2 wages.
- $60,000 × 92.35% = $55,410 of net earnings from self-employment
- $55,410 × 15.3% = $8,477.73 of self-employment tax
- Half of that, $4,238.87, is deductible when you figure your adjusted gross income
Income tax
On top of self-employment tax you owe regular income tax on your profit (after the deduction above, your standard or itemized deduction, and any qualified business income deduction), plus state tax where it applies. The worksheet in Form 1040-ES walks through it. For a quick planning number, many freelancers set aside a flat 25–30% of every payment, but your real rate depends on your income, state and deductions. Our quarterly tax set-aside calculator turns a percentage into a dollar amount.
How to pay
The IRS accepts estimated payments online through IRS Direct Pay or your IRS online account (where you can also see past payments), by phone, through the IRS app, through EFTPS, or by mailing a check with a Form 1040-ES voucher. A mailed payment counts as paid on its U.S. postmark date. You can also pay more often than quarterly, such as monthly, as long as enough is paid by each due date.
A simple system that works
- Open a separate savings account just for taxes. Our business bank account guide covers free options, some with built-in tax buckets.
- Every time a client pays you, move your set-aside percentage into it.
- Put the four due dates in your calendar with a one-week reminder.
- On each date, pay at least one quarter of your safe-harbor amount.
- Track deductible expenses all year so your April bill is as low as it legally can be.

FAQ
What happens if I miss a quarterly payment?
The IRS may charge an underpayment penalty, which works like interest on the amount that was late. Pay as soon as you can to stop it growing. The penalty can be waived in some cases, such as a casualty or disaster.
Is it too late to pay for 2026 if I skipped earlier quarters?
No. Paying now reduces any penalty, and the fourth payment is due January 15, 2027. Earlier quarters that were underpaid may still carry a penalty for the time they were late.
Do I pay state estimated taxes too?
Most states with an income tax have their own estimated payment rules and dates. Check your state tax agency's website.
I started freelancing mid-year. Do I owe the earlier quarters?
Estimated tax is tied to when you earn income. If you had no freelance income early in the year, you generally start with the payment period in which you first earn it. The annualized method on Form 2210 Schedule AI helps you show that.
Where do I find the official numbers?
