Key dates
The next IRS deadlines
These are the general dates. Your state may have others, and if one falls on a weekend or holiday it moves to the next business day.
- Estimated quarterly payment (Q4)
- S-Corp and partnership returns
- Estimated quarterly payment (Q1) and personal return
- Estimated quarterly payment (Q2)
- Estimated quarterly payment (Q3)
- Deadline if you requested an extension
An extension gives you more time to file the return, but not to pay what you owe.
