The Freelancer's Guide to Quarterly Estimated Tax Payments
Who needs to pay estimated taxes, when they're due, how to calculate them, and what happens if you miss a payment.
What Are Estimated Tax Payments?
If you're self-employed, a freelancer, or have significant income that isn't subject to withholding, the IRS expects you to pay taxes throughout the year — not just at filing time. These are called quarterly estimated tax payments.
Who Needs to Pay?
You generally need to make estimated payments if you expect to owe $1,000 or more in taxes after subtracting withholding and credits. This typically applies to:
- Freelancers and independent contractors
- Sole proprietors and LLC members
- Partners and S-Corp shareholders
- Individuals with significant investment income
- Anyone with rental income
When Are They Due?
Estimated taxes are due quarterly:
- Q1: April 15, 2026
- Q2: June 15, 2026
- Q3: September 15, 2026
- Q4: January 15, 2027
How to Calculate
There are two common methods:
Method 1: Prior Year Safe Harbor
Pay 100% of last year's total tax liability (110% if your AGI was over $150,000), divided into four equal payments. This guarantees no underpayment penalty regardless of how much you earn this year.
Method 2: Current Year Estimate
Estimate your current year income and calculate 90% of the expected tax. This method results in lower payments if your income decreased, but requires accurate projections.
What Happens If You Don't Pay?
The IRS charges an underpayment penalty, which is essentially interest on what you should have paid. For 2026, the penalty rate is approximately 8% annualized. It's calculated per quarter, so even missing one payment triggers a penalty.

Our Recommendation
Set up automatic quarterly reminders and use a dedicated savings account for taxes. A good rule of thumb is to set aside 25–30% of every payment you receive for taxes.
