FAQ
Who needs to pay quarterly taxes?
You must pay quarterly estimated taxes if you expect to owe $1,000 or more in taxes when you file and your withholding will be less than 90% of your current year tax (or 100% of prior year tax). This typically applies to self-employed individuals, freelancers, and investors.
What are the 2026 quarterly tax due dates?
For 2026: Q1 is due April 15, Q2 is due June 16 (moved from 15th due to holiday), Q3 is due September 15, and Q4 is due January 15, 2027. If the due date falls on a weekend or holiday, it moves to the next business day.
What happens if I underpay quarterly taxes?
The IRS charges an underpayment penalty if you don't pay enough throughout the year. To avoid penalties, pay at least 90% of current year tax OR 100% of prior year tax (110% if AGI over $150K). Use Form 2210 to calculate any penalty.
