Intent to Terminate Installment Agreement (CP523)

A CP523 rarely means the IRS changed its mind about your deal. It means one of the agreement's standing conditions broke:

• A missed or short monthly payment, including a bounced direct debit after a cash-flow crunch.
• A new balance on a later year. Every agreement requires you to stay current; filing a new return with tax due and no payment defaults the plan. This is the classic founder trap: quarterly estimated tax payments get skipped during a tight stretch, and the next April return quietly breaks the agreement.
• A missing return. Not filing on time violates the compliance condition even if you owe nothing new.
• A requested financial update you did not provide, on agreements subject to periodic review.

If you are not sure which condition tripped, the notice states the reason, and your account transcript will confirm it. Our guide to estimated tax safe harbors shows how to keep the current year from defaulting the next plan.

For 30 days, the agreement is in default but not dead. Call the number on the notice, cure the default, and the plan can generally be reinstated, though the IRS notes "you may have to pay a fee to reinstate it" and may require any new balance to be addressed. After termination, three things get worse at once:

• The account returns to active collections, and the IRS may file a federal tax lien or proceed toward levying wages and bank accounts.
• Qualifying individual taxpayers lose the reduced 0.25% monthly failure-to-pay rate that applies during an approved plan; the standard rate resumes.
• You spend negotiating capital rebuilding an agreement you already had.

In order of preference:

1. Cure and reinstate. Make up the missed payment or file the missing return, then call to reinstate. If the default came from a new balance, ask to have the new year rolled into a restructured agreement rather than starting over.
2. Restructure. If the old payment no longer fits your cash flow, propose a new amount backed by current financials. A realistic smaller payment beats a repeated default. The options are laid out in our payment plan guide.
3. Appeal the termination. The notice explains your right to appeal, and a pre-termination appeal through the Collection Appeals Program can hold enforcement off while the dispute is heard.
4. Switch strategies. If the plan was never affordable, a default is the signal to evaluate an offer in compromise or currently not collectible status instead of chaining reinstatements.

Business owners on agreements for payroll balances should treat a CP523 with extra urgency: business agreements default the same ways individual ones do, but the enforcement that follows tends to move faster and reaches deposits, receivables, and business bank accounts that the company needs to make the next payroll at all.
