IRS Notice Library

Match the CP or LT code on your letter to understand why the IRS contacted you and what to do next.

The IRS says you owe tax. It usually follows a return filed without full payment, or an IRS correction that created a balance.

A reminder that the balance from your first notice is still unpaid, with updated interest and penalties.

A second reminder with a firm due date. The IRS is getting closer to formal collection.

A letter pointing you to IRS online tools to view your balance, pay, or request a plan.
