What to do this week

  1. Pay or set up an installment agreement at irs.gov; this is the easiest point to stop the sequence.
  2. If the balance is wrong, call the number on the notice.
  3. If you cannot pay anything, gather your income and expense figures; Currently Not Collectible status may apply.

The notice number is printed in the top right corner of the letter. Match it before doing anything else; scammers mail fake IRS letters, and a real one can be confirmed at irs.gov/account, where the same balance will appear.

When to get help

  • You are not sure which years are involved.
  • You have other IRS letters you have not opened.
