Key Tax Deadlines
Individual Tax Returns
The standard deadline for filing individual tax returns (Form 1040) is April 15th of each year. If this date falls on a weekend or holiday, the deadline shifts to the next business day. For 2024, the deadline is April 15th, a Monday.
Extension Deadlines
If you need more time, you can file Form 4868 for an automatic six-month extension, moving your filing deadline to October 15th. Remember:
- An extension gives you more time to file
- It does not give you more time to pay
- You must estimate and pay taxes owed by April 15th to avoid penalties
Business Tax Returns
Different business structures have specific deadlines:
| Business Type | Standard Deadline |
|---|---|
| S-Corporations | March 15th |
| Partnerships | March 15th |
| C-Corporations | April 15th |
