Filing Extensions

If you need more time to file, you can request an automatic extension using Form 4868, which extends your filing deadline to October 15, 2024.

An extension of time to file is NOT an extension of time to pay. Any taxes owed must still be paid by the original deadline to avoid penalties and interest.

Important Documents to Gather

Before filing, ensure you have:

  • W-2 forms from employers
  • 1099 forms for contract work
  • Mortgage interest statements
  • Property tax records
  • Charitable donation receipts
  • Medical expense records
  • Investment income statements
