What a CP503 means
The CP503 is a firmer reminder about the same unpaid balance. Its tone is more urgent than earlier notices, and it warns that the IRS may file a Notice of Federal Tax Lien if the balance isn't resolved.
Why it matters
Two things change around this point. First, the next notice in the sequence, the CP504, gives the IRS authority to take your state income tax refund. Second, a federal tax lien can be filed. A filed lien is a public claim against everything you own, including property you acquire later.
Act before the date on the notice. Setting up a payment plan or paying now usually keeps the account from escalating further.
What happens if you ignore it
The IRS typically sends a CP504, its notice of intent to levy. After that comes the final notice, LT11 or Letter 1058, which opens a 30-day window to request a hearing before the IRS can levy wages, bank accounts and other assets.
Your options
Pay in full, a short-term plan, an installment agreement, penalty abatement, and for people who truly can't pay, currently not collectible status or an Offer in Compromise. Which fits depends on your income, expenses, assets and filing history. See all resolution options.

Questions about the CP503
What comes after a CP503?
Usually a CP504, the IRS's notice of intent to levy, which lets it take your state income tax refund. After that comes the final notice of intent to levy (LT11 or Letter 1058).
Will the IRS file a lien after a CP503?
It can. The IRS may file a Notice of Federal Tax Lien once a balance remains unpaid after notice and demand. Getting a payment plan in place can reduce that risk, and some plans make a lien withdrawal possible later.
Can I still resolve this without a lien or levy?
Often, yes. Paying in full or setting up a payment plan now usually stops the account from escalating.
Do I need to file missing returns first?
In most cases, yes. The IRS generally won't approve a payment plan or settlement until all required returns are filed.
