What tax years and deadline apply?

The letter names the tax years to address and a deadline for your response. Both are printed in the letter.

  • Read the tax years listed in the letter.
  • Note the response deadline.
  • Gather returns and records for those years.

What happens if you ignore it?

If you do not respond, the IRS may send another notice or open an examination of the listed years. The IRS can also assess penalties and interest if tax is owed.

  • Whether a return was filed for each year.
  • Whether the listed transactions were reported.
  • Whether tax is owed for those years.
