If you're a freelancer, gig worker, or self-employed professional, the IRS expects you to pay taxes throughout the year—not just on April 15th. These are called quarterly estimated tax payments, and failing to make them can result in penalties and a nasty surprise at tax time.
In this guide, we'll walk you through everything you need to know: who needs to pay, how to calculate your payments, when they're due, and how to actually submit them.
⚠️ Do You Need to Pay Quarterly Taxes?
You're required to make quarterly payments if you expect to owe $1,000 or more in taxes when you file your return. Most freelancers earning over $5,000/year in self-employment income will meet this threshold.
2026 Quarterly Tax Due Dates
For the 2026 tax year, here are the four quarterly payment deadlines:
Q1 Payment Due
For income earned January 1 – March 31, 2026
Q2 Payment Due
For income earned April 1 – May 31, 2026
Q3 Payment Due
For income earned June 1 – August 31, 2026
Q4 Payment Due
For income earned September 1 – December 31, 2026 (paid in January 2027)
How to Calculate Your Quarterly Payment
There are two main methods to calculate your estimated taxes:
Method 1: Prior Year Safe Harbor (Easiest)
The simplest approach is to pay 100% of last year's total tax liability, divided into four equal payments. This protects you from underpayment penalties even if you earn more this year.
Example: If you owed $8,000 last year → Pay $2,000 per quarter
Note: If your adjusted gross income was over $150,000 last year, you need to pay 110% of last year's tax to use the safe harbor method.
Method 2: Current Year Estimate
If your income varies significantly or this is your first year self-employed, estimate your current year's tax:
Estimate Your Annual Income
Add up all expected income from freelance work, gig apps, and other sources for the year.
Subtract Deductions
Subtract business expenses (mileage, supplies, home office, etc.) and the standard deduction ($14,600 for single filers in 2026).
Calculate Self-Employment Tax
Multiply your net self-employment income by 15.3% (Social Security + Medicare). You can deduct half of this from your income.
Calculate Income Tax
Apply the tax brackets to your taxable income to find your income tax.
Divide by 4
Add self-employment tax + income tax, then divide by 4 for your quarterly payment.
Example Calculation
Let's say you're a freelance designer expecting to earn $60,000 this year:
| Gross Income | $60,000 |
| Business Expenses | - $8,000 |
| Net Self-Employment Income | $52,000 |
| Self-Employment Tax (15.3% × 92.35%) | $7,347 |
| ½ SE Tax Deduction | - $3,674 |
| Standard Deduction | - $14,600 |
| Taxable Income | $33,726 |
| Income Tax (approximate) | $3,800 |
| Total Annual Tax | $11,147 |
| Quarterly Payment | $2,787 |
How to Pay Your Quarterly Taxes
You have several options for making your payment:
1. IRS Direct Pay (Recommended)
The fastest, free way to pay. Go to irs.gov/payments, select "Make a Payment," and pay directly from your bank account. No registration required.
2. EFTPS (Electronic Federal Tax Payment System)
Best for recurring payments. Create an account at eftps.gov and schedule payments in advance.
3. Credit or Debit Card
Pay through IRS-approved processors (fees apply: 1.85-2% for credit cards, flat fee for debit).
4. Mail a Check
Send a check with Form 1040-ES voucher to the IRS. Allow 2-3 weeks for processing.
💡 Pro Tip: Set Up Automatic Payments
Many freelancers find it easier to set aside 25-30% of each payment into a separate savings account, then make one quarterly payment. This prevents the "I don't have the money" problem.
What Happens If You Don't Pay?
The IRS charges an underpayment penalty if you don't pay enough throughout the year. Currently, the penalty rate is around 8% annually on the underpaid amount.
You can avoid penalties if you:
- Owe less than $1,000 when you file
- Paid at least 90% of this year's tax
- Paid 100% of last year's tax (110% if AGI > $150,000)
Adjusting Your Payments Mid-Year
If your income changes significantly during the year, you can adjust your future quarterly payments:
- Income dropped? Reduce your future payments to avoid overpaying
- Big new contract? Increase payments to avoid underpayment penalties
Use IRS Form 2210 to calculate any penalty adjustments based on when you actually earned the income.
