Key Tax Filing Deadlines
Individual Tax Returns
For most taxpayers in the United States, the deadline to file individual tax returns (Form 1040) is April 15. However, if April 15 falls on a weekend or holiday, the deadline shifts to the next business day.
Business Tax Returns
- Partnerships and S Corporations: These entities must file their returns by March 15 (Form 1065 for partnerships and Form 1120S for S corporations)
- C Corporations: The deadline for C corporations to file their tax returns (Form 1120) is April 15
Quarterly Estimated Taxes
Self-employed individuals and those with significant non-wage income must pay estimated taxes quarterly:
- April 15 (for January 1 - March 31)
- June 15 (for April 1 - May 31)
- September 15 (for June 1 - August 31)
- January 15 (for September 1 - December 31)
Extensions and Penalties
Filing for an Extension
If you cannot file your tax return by the deadline, you can request an extension using Form 4868. This grants an automatic six-month extension to October 15. Important notes:
- The extension must be filed by the original due date
- This is an extension to file, not to pay
- Any taxes owed are still due by the original deadline
- Interest and penalties may apply to unpaid balances
Penalties for Late Filing
"Filing late can be costly. The penalty for filing late is normally 5% of the unpaid taxes for each month or part of a month that a tax return is late." - IRS
The IRS imposes a 5% penalty of unpaid taxes for each month the return is late, up to 25%. If you file more than 60 days late, the minimum penalty is either $435 or 100% of the unpaid tax, whichever is less.
Special Circumstances
Natural Disasters
The IRS often provides relief to taxpayers affected by natural disasters, extending deadlines for those in federally declared disaster areas. Visit the IRS disaster relief page for updates.
Military Personnel
Active duty military personnel serving in a combat zone typically receive automatic extensions:
- 180 days after leaving the combat zone
- Additional time for hospitalization due to injuries
State Tax Deadlines
Most states align with federal deadlines, but some variations exist:
| State | Filing Deadline |
|---|---|
| Virginia | May 1 |
| Delaware | April 30 |
| Louisiana | May 15 |
Tips for Timely Filing
- Organize Your Documents: Gather all necessary documents, such as W-2s, 1099s, and receipts for deductions, well before the deadline

Remember to keep copies of your tax returns and supporting documents for at least three years after filing or two years from the date you paid the tax, whichever is later.
