A CP523 says the IRS plans to end your installment agreement because its terms weren't met, and to levy your assets if you don't act. The notice gives the reason. source 1
The IRS covers the CP523 and the CP623 on the same page. source 1
A missed payment is the usual cause, but not the only one. The fix depends on which term was missed, so we read the reason first.
The date that counts
The IRS page says to contact it as soon as possible, and no later than a set number of days from the date of the notice. The notice prints the date. Pay before your termination date to keep the agreement. source 1
Why people get one
- A plan payment was missed or short.
- A new tax balance showed up while the plan was running.
- Another term of the agreement wasn't met.
First steps
- Read the reason the notice gives for ending the plan. source 1
- Check your IRS online account (typed in yourself at irs.gov) to confirm the notice is real and see the balance and any payments already posted.
- Pay what is needed before the termination date to keep the agreement in place. source 1
- Call the number printed on your notice to ask about reinstating the agreement. The IRS says a reinstatement fee may apply, or a new balance may need to be paid in full. source 1
- If you already fixed the problem, call anyway so the IRS has a record and can reinstate the plan. source 1
What not to do
- Don't let it pass. The IRS says it will end the agreement and may file a lien or levy wages or bank accounts. source 1
- Don't pay through a link or phone number from an unexpected email or text. Use irs.gov, typed in yourself.
- Don't assume a disagreement has to end at the phone call. The IRS says you can appeal to the Independent Office of Appeals. source 1
