Common questions
What happens if I miss a quarterly estimated payment?
The IRS charges interest from the due date, so a late payment costs more than just the tax owed. Add the deadlines to your calendar in one click and pay on time.
When are the 2026 quarterly due dates?
The standard IRS schedule applies. If a date falls on a weekend or holiday it shifts to the next business day — confirm edge cases at irs.gov.
Do I have to pay estimated taxes?
If you expect to owe $1,000 or more in tax for the year and it isn't covered by withholding, the IRS expects quarterly estimated payments. This tool tracks the dates; the 1099 Estimator covers the amounts.
