Understanding the CP259 Notice

  • What is a CP259 Notice?

    The IRS issues a CP259 Notice when it believes you didn’t file a required
    tax return.
  • When businesses typically get it

    This notice is often sent for missing returns like Forms 941, 940, 943, 944, 945, 1120, or 1065.
  • What is the deadline to respond to the notice?

    The IRS generally provides 10 days from the date on the notice to submit a response.
  • Why a timely response is critical?

    Ignoring it may lead to penalties, interest, or the IRS assessing the unfiled return on your behalf.
