Understanding Tax Filing Deadlines
For most U.S. taxpayers, the standard federal tax filing deadline is April 15th. However, when this date falls on a weekend or holiday, the deadline shifts to the next business day. For 2024, the key date for filing 2023 tax returns is April 15, 2024.
Individual Tax Filing Extensions
If you need more time, you can request an automatic extension using Form 4868, which gives you until October 15th to file. Important considerations:
- An extension of time to file is not an extension of time to pay
- Any taxes owed must still be paid by April 15 to avoid penalties
- Interest will accrue on unpaid balances starting April 16
Business Tax Filing Deadlines
Different business entities have varying deadlines:
- Sole Proprietorships and Single-Member LLCs: File using Form 1040 by April 15th
- Partnerships and Multi-Member LLCs: File Form 1065 by March 15th (can extend to September 15th)
- S Corporations: File Form 1120S by March 15th (can extend to September 15th)
- C Corporations: File Form 1120 by April 15th (can extend to October 15th)
