Not if you pay the full amount by the due date on the payment coupon. However, interest will accrue on the unpaid balance after that date.

  • Consider filing your taxes electronically.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
