Who Needs to Pay Quarterly Taxes?
If you're a freelancer, independent contractor, business owner, or have significant income without withholding (rental income, investments), you likely need to pay estimated quarterly taxes. The general rule: if you expect to owe $1,000 or more in taxes after subtracting withholding and credits, you must make quarterly payments.
2026 Payment Deadlines
- Q1 (January-March): April 15, 2026
- Q2 (April-May): June 15, 2026
- Q3 (June-August): September 15, 2026
- Q4 (September-December): January 15, 2027
Note: If the deadline falls on a weekend or federal holiday, it extends to the next business day.
How to Calculate Your Quarterly Payments
Method 1: Income Estimation
- Estimate your total gross income for the year
- Subtract business deductions (expenses, mileage, home office)
- Calculate self-employment tax (15.3% on 92.35% of net income)
- Calculate federal income tax using 2026 brackets
- Add state taxes if applicable
- Divide the total by 4 for your quarterly payment
Method 2: Safe Harbor Rule
To avoid penalties, pay at least 100% of last year's taxes (110% if your adjusted gross income was over $150,000). This method is simpler but may result in overpayment if your income decreased.
Key Takeaways

- Deadlines are April 15, June 15, September 15, and January 15
- Use the safe harbor rule to avoid underpayment penalties
