Critical Rules for On-Time Filing
1. The “Day Before” Rule (EFTPS)
If you use the Electronic Federal Tax Payment System (EFTPS), you cannot wait until the actual due date to hit “send.”
2. Disaster Extensions
If you reside in an area affected by a natural disaster, you may be eligible for automatic extensions.
- Action: Visit the IRS “Around the Nation” page to see if your state or county has been granted extra time to file and pay.
