When you work for an employer, taxes come out of every paycheck. When you freelance, nobody withholds anything, so the IRS expects you to pay during the year through quarterly estimated taxes. Skip them and you can owe a penalty, even if you pay everything in April. This guide explains quarterly estimated taxes for freelancers, with a free 2026 calculator.
Short answer: if you expect to owe $1,000 or more in federal tax for the year, you generally need to make quarterly estimated payments using Form 1040-ES. For the 2026 tax year, the deadlines are April 15, June 15 and September 15, 2026, and January 15, 2027. Most freelancers set aside 25–30% of profit; use the calculator below for a personal estimate.
Key takeaways
- You owe self-employment tax (15.3% on 92.35% of net earnings, with the 12.4% Social Security part capped at $184,500 for 2026) plus income tax.
- Pay estimated taxes if you expect to owe $1,000+ after withholding and credits.
- Safe harbor: pay 90% of this year’s tax or 100% of last year’s tax (110% if last year’s AGI was over $150,000) to avoid penalties.
- Pay online with IRS Direct Pay, your IRS Online Account or EFTPS.
- Most states with an income tax also require quarterly estimates.
2026 quarterly estimated tax calculator (federal)
Estimate only. Assumes the standard deduction, no other income, and the full 20% QBI deduction. Doesn’t include the 0.9% Additional Medicare Tax, credits or other deductions.
The calculator uses 2026 federal brackets and standard deductions published by the IRS ($16,100 single / $32,200 married filing jointly). It’s a planning tool, not tax advice.
Quarterly estimated tax deadlines
| Payment | Income earned | Due date (2026 tax year) | Due date (2027 tax year) |
|---|---|---|---|
| Q1 | January 1 – March 31 | April 15, 2026 | April 15, 2027 |
| Q2 | April 1 – May 31 | June 15, 2026 | June 15, 2027 |
| Q3 | June 1 – August 31 | September 15, 2026 | September 15, 2027 |
| Q4 | September 1 – December 31 | January 15, 2027 | January 18, 2028* |
*If a due date falls on a weekend or legal holiday, the payment is on time if made the next business day, according to the IRS. January 15, 2028 is a Saturday and Monday, January 17 is a federal holiday, so the deadline moves to January 18. Notice that the “quarters” aren’t equal: Q2 covers only two months.
Who has to pay quarterly estimated taxes for freelancers?
According to the IRS, individuals generally must make estimated payments if they expect to owe $1,000 or more when they file. For freelancers that’s almost everyone with meaningful profit, because self-employment tax alone on $10,000 of profit is about $1,400.
You may not need to pay if you also have a W-2 job and increase your withholding enough to cover your freelance income, or if you had no tax liability in the prior year and were a US citizen or resident for the whole year.
How much should you pay?
1. Estimate your self-employment tax
Self-employment tax covers Social Security and Medicare. It’s 15.3% of 92.35% of your net earnings: 12.4% for Social Security (on earnings up to $184,500 in 2026) and 2.9% for Medicare (no cap). An additional 0.9% Medicare tax applies above $200,000 (single) or $250,000 (married filing jointly). You can deduct half of your self-employment tax when calculating income tax.
2. Estimate your income tax
Start with your net profit, subtract half your self-employment tax, the standard deduction and, for most freelancers, the qualified business income (QBI) deduction of up to 20%. Then apply the 2026 brackets:
| Rate | Single | Married filing jointly |
|---|---|---|
| 10% | Up to $12,400 | Up to $24,800 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 |
| 22% | $50,401 – $105,700 | $100,801 – $211,400 |
| 24% | $105,701 – $201,775 | $211,401 – $403,550 |
| 32% | $201,776 – $256,225 | $403,551 – $512,450 |
| 35% | $256,226 – $640,600 | $512,451 – $768,700 |
| 37% | Over $640,600 | Over $768,700 |
3. Use the safe harbor if your income is unpredictable
If your income swings a lot, the simplest way to avoid penalties is the prior-year safe harbor: pay at least 100% of last year’s total tax (110% if your AGI was over $150,000), split into four payments. You might still owe more in April, but you won’t owe an underpayment penalty.
Example: your 2025 total tax was $12,000 and your AGI was under $150,000. Paying $3,000 each quarter in 2026 protects you from the penalty, even if your 2026 income grows.
How to pay estimated taxes
- IRS Direct Pay (free, from your bank account). Choose “Estimated Tax” and the 1040-ES form.
- IRS Online Account, where you can also see past payments.
- EFTPS (Electronic Federal Tax Payment System), which lets you schedule payments in advance.
- Debit or credit card through IRS-approved processors (fees apply).
- Mail a check with the Form 1040-ES voucher.
Keep confirmation numbers and note each payment in your accounting software. You’ll report the total on your Form 1040.
What happens if you miss a payment?
The IRS charges an underpayment penalty, which works like interest, calculated on how much you underpaid and for how long. It applies per quarter, so paying late is better than not paying. If your income is uneven (for example, most of it arrives in Q4), the annualized income installment method on Form 2210 can reduce or eliminate the penalty.
A simple system for setting money aside
- Open a separate savings account just for taxes.
- Move 25–30% of every client payment into it the day it arrives. Use the calculator above to fine-tune your percentage.
- Set calendar reminders a week before each due date.
- Recalculate after each quarter using your actual profit.
Good tools make this automatic. See our guide to the best accounting software for freelancers, several of which include tax estimates. Your business structure also matters; compare LLC vs. sole proprietorship.
Frequently asked questions
What percentage should freelancers set aside for taxes?
Many freelancers set aside 25–30% of net profit to cover self-employment tax and federal income tax, plus more in states with income tax. Use the calculator on this page for a personalized estimate.
When are quarterly taxes due for 2026?
For the 2026 tax year, estimated payments are due April 15, June 15 and September 15, 2026, and January 15, 2027.
Do I have to pay quarterly taxes in my first year of freelancing?
If you expect to owe $1,000 or more, generally yes. If you had a full-year W-2 job last year, the prior-year safe harbor can make your first year easier: paying 100% (or 110%) of last year’s tax in installments avoids penalties.
What happens if I don’t pay estimated taxes?
You may owe an underpayment penalty for each quarter you underpaid, plus the tax itself when you file. Paying late reduces the penalty compared with not paying.
Do I need to pay state estimated taxes too?
Most states with an income tax require quarterly estimates with similar deadlines. States without income tax, such as Texas and Florida, don’t.
