What are quarterly estimated taxes?
When you work as a freelancer or self-employed individual, no employer withholds taxes from your payments. As a result, the IRS requires you to pay your estimated taxes yourself — four times per year. This is what our freelancer quarterly tax calculator helps you plan for.
Quarterly estimated taxes cover two separate obligations: self-employment (SE) tax and federal income tax. Together, these can add up to 25–40% of your net income, depending on your earnings and filing status.
Who needs to pay quarterly taxes?
The IRS generally requires you to pay quarterly estimated taxes if you expect to owe at least $1,000 in federal tax for the year after subtracting withholding and credits. This applies to:
- Freelancers and independent contractors
- Self-employed business owners
- 1099 workers of any kind
- Gig economy workers (Uber, Fiverr, Upwork, etc.)
- Anyone with significant income outside of a salaried job
When are quarterly taxes due?
The IRS sets four quarterly deadlines each year. Missing these deadlines can result in an underpayment penalty, even if you pay the full amount by April 15. Therefore, staying on schedule is just as important as paying the correct amount.
| Quarter | Income Period | Due Date |
|---|---|---|
| Q1 2025 | January 1 — March 31 | April 15, 2025 |
| Q2 2025 | April 1 — May 31 | June 15, 2025 |
| Q3 2025 | June 1 — August 31 | September 15, 2025 |
| Q4 2025 | September 1 — December 31 | January 15, 2026 |
How is self-employment tax calculated?
Our freelancer quarterly tax calculator uses the official IRS method to calculate your self-employment tax. Specifically, SE tax is calculated on 92.35% of your net self-employment income — not the full amount. This adjustment accounts for the fact that employers normally pay half of Social Security and Medicare taxes on behalf of their employees.
SE tax breakdown
The 15.3% SE tax rate consists of two parts — 12.4% for Social Security (on income up to $168,600 in 2024) and 2.9% for Medicare (on all income with no cap). Furthermore, you can deduct 50% of your SE tax from your gross income before calculating your federal income tax, which reduces your overall tax burden.
Federal income tax for freelancers
In addition to SE tax, you owe federal income tax on your net self-employment income at the standard bracket rates. However, as a self-employed person you can also deduct the standard deduction and the 50% SE tax deduction before your taxable income is calculated. As a result, your actual income tax is typically lower than it first appears.
| Tax Rate | Single filer | Married filing jointly |
|---|---|---|
| 10% | $0 — $11,600 | $0 — $23,200 |
| 12% | $11,601 — $47,150 | $23,201 — $94,300 |
| 22% | $47,151 — $100,525 | $94,301 — $201,050 |
| 24% | $100,526 — $191,950 | $201,051 — $383,900 |
| 32% | $191,951 — $243,725 | $383,901 — $487,450 |
| 35% | $243,726 — $609,350 | $487,451 — $731,200 |
| 37% | Over $609,350 | Over $731,200 |
Tips to avoid underpayment penalties
The IRS charges an underpayment penalty if you do not pay enough tax throughout the year. Fortunately, there are several straightforward ways to stay compliant and avoid surprises.
Follow the safe harbor rules
- Pay at least 90% of this year's tax liability — if your total payments cover 90% or more of what you owe, the IRS will not charge an underpayment penalty.
- Pay 100% of last year's tax liability — alternatively, if you pay at least as much as your total tax bill from the previous year, you are fully protected. If your income was over $150,000 last year, this threshold rises to 110%.
Set aside money every month
- Save 25–30% of every payment — as a general rule, setting aside around 25–30% of each client payment you receive covers both SE tax and federal income tax for most freelancers.
- Open a separate tax savings account — keeping your tax money in a dedicated account prevents you from accidentally spending it before the quarterly deadline.
- Track expenses throughout the year — every legitimate business deduction reduces your taxable income and consequently lowers your quarterly tax bill.
Important — if you miss a quarterly deadline or underpay, the IRS charges a penalty based on the federal short-term interest rate plus 3%. Use our freelancer quarterly tax calculator every quarter to stay on track.
