On the paper
Read the exact action described, the tax period, the amount, and the date printed in the notice. Do not rely on the code alone.
Find the date printed on your notice or letter. The paper notice and the current official IRS instructions control, even where this page differs.
General next steps
- Confirm whether the notice concerns the correct tax year and taxpayer.
- If you already paid, collect payment confirmation and follow the notice contact instructions.
- If you need more time or cannot pay, review the official IRS payment and collection information promptly.
Timing
CP504 tells you to pay immediately and the individual notice controls the action and date for your account.
