Missed the tax extension deadline yesterday? Here is what you need to know now. ⏳
Wednesday, October 15 was the final federal income tax extension deadline for individuals and C corporations. If you requested a six-month extension back in April, your paperwork was due yesterday.
Keep these important facts in mind:
• 💸 Extension vs. Payment: Remember, an extension only gives you more time to file your forms—not more time to pay. Taxes owed were still due on April 15.
• ⚠️ Late Penalties: Filing your return after October 15 without a valid reason or special disaster relief can trigger a failure-to-file penalty. This is usually 5% of your unpaid taxes per month.
• 🏢 Business Deadlines: Partnerships and S corporations already hit their extension deadline last month on September 15.
What to do if you missed it: Don't panic, but don't wait! File your return as soon as possible to stop late penalties from growing. The IRS offers payment plans if you owe money and can't pay the full balance right now.
