Most people who open a CP504 have already set aside two or three earlier IRS letters. We see it every month at Dahir Tax and Accounting Firm.
This notice carries real consequences, but it also marks the point where fixing the problem still costs the least. Your 30 days count from the notice date printed on the letter.
Key Points
- After 30 days, the IRS can take your state tax refund.
- A payment plan or appeal filed now usually stops the next step.
What a CP504 Legally Means
The IRS titles the CP504 a Notice of Intent to Levy under Internal Revenue Code section 6331(d). According to the IRS page that explains this notice, it serves as a final reminder that the agency intends to levy wages, bank accounts, or a state tax refund, and that it will begin searching for other assets.
The same page warns that the IRS can also file a Notice of Federal Tax Lien if it hasn’t already.
Here is the part most summaries blur. The Taxpayer Advocate Service explains that if the IRS does not receive payment within 30 days of the notice date, it can levy your state tax refund.
For wages and bank accounts, the IRS generally has to send one more letter first: the LT11 or Letter 1058, which gives you 30 days to request a Collection Due Process hearing. Two exceptions skip that step, the Disqualified Employment Tax Levy and the Federal Contractor Levy. IRS Publication 594 explains both.
The notice also includes a passport warning. Under the FAST Act, the IRS can certify “seriously delinquent” tax debt to the State Department. For 2026, the IRS sets that threshold at $66,000 in combined tax, penalties, and interest, and certification only happens after a lien or levy.
Where CP504 Falls in the IRS Notice Sequence
| Notice | What it means | What the IRS can do next |
|---|---|---|
| CP14 | First bill for the balance | Send reminders |
| CP501 | Reminder | Send another reminder |
| CP503 | Second reminder with stronger language | Move you to CP504 |
| CP504 | Notice of Intent to Levy | Take your state refund after 30 days, file a lien, search for assets |
| LT11 or Letter 1058 | Final Notice of Intent to Levy with hearing rights | Levy wages, bank accounts, and other property after 30 days |
Not every taxpayer receives every letter in this order. TheStreet reported in July 2026 that the sequence can reach the CP504 stage in as little as 90 days.
The Numbers Say the IRS Is Collecting Again
The IRS paused most collection activity during Covid, and some people learned that IRS mail could wait. CNBC reported in 2026 that lien filings rose largely because enforcement returned to prepandemic levels. The IRS Data Book for fiscal year 2025 shows how far that return has gone:
- The IRS filed 214,099 Notices of Federal Tax Lien in FY2025, compared with 196,996 in FY2024 and 179,019 in FY2023.
- It requested 339,137 notices of levy on third parties such as banks and employers in FY2025, up from 313,792 the year before.
- Lien filings grew about 36% from FY2022, based on the same Data Book table as reported by the Tax Policy Center.
Interest keeps running the whole time. The IRS set the individual underpayment rate at 7% per year, compounded daily, for the quarter starting October 1, 2026.
The failure to pay penalty adds 0.5% per month (capped at 25%), and IRS penalty guidance says it rises to 1% per month once 10 days pass after a notice of intent to levy. On a $20,000 balance, that jump alone costs an extra $100 a month.
Phones won’t save you time either. IRS Solutions, a tax resolution software company, reported that IRS assistors answered 21% of 48.1 million calls during the 2026 filing season, with average holds of 14 minutes.
A 30 Day Response Plan
Here’s how we would work a CP504 if it landed on your kitchen table today.
- Days 1 to 3: Find the notice date. Log in to your IRS online account and check the balance and payment history. The IRS itself says recent payments can take time to post, so a mismatch may simply mean a payment in transit.
- Days 4 to 10: Look for unfiled returns. The IRS generally won’t approve a payment plan while you have missing returns, and a missing year can quietly add a second balance.
- Days 11 to 20: Choose your path from the table below and apply. The IRS Online Payment Agreement tool usually tells you on the spot whether it approved your plan.
- Days 21 to 30: If you believe the IRS got the balance wrong, call the number on the notice or request a Collection Appeals Program review before collection starts. Keep copies of everything you send.
Resolution Options Compared
| Option | Who it fits | Cost or catch |
|---|---|---|
| Pay in full | You can cover the balance now | Stops interest and penalties |
| Short term payment plan | You owe less than $100,000 and can pay within 180 days | No setup fee; interest continues |
| Long term payment plan (online) | Individuals owing $50,000 or less | $22 setup with direct debit, $69 without; low income applicants may qualify for reduced or waived fees |
| Offer in compromise | You can’t realistically pay in full | $205 application fee; the IRS reviews assets, income, and expenses, and review takes months |
| Currently not collectible | You can’t cover basic living expenses | The IRS pauses collection, but interest and penalties keep growing and a lien may still follow |
| Collection Appeals Program | You dispute the collection action | You must request it before the levy happens |
Fees reflect the IRS payment plan and offer in compromise pages at the time of writing. Check them before you apply.
Our Take: Don’t Wait for the “Real” Final Notice
Several tax resolution firms, including Omni Tax Help and TaxSmith, point out that CP504 isn’t technically the final notice. That’s accurate. We think people draw the wrong lesson from it.
Choice Tax Relief notes that the LT11 generally arrives about five weeks after the CP504. Five weeks goes fast when you’re hunting for bank statements and old returns. By the LT11 stage, you negotiate under a 30 day hearing deadline, possibly with a lien already on public record.
At the CP504 stage, most individuals who owe $50,000 or less can set up a payment plan online in one sitting, without submitting a full financial statement.

A Note for Business Owners
Businesses receive the CP504B instead. The IRS explains that its State Income Tax Levy Program currently applies only to individual state refunds, though it may extend to business refunds in the future.
Payroll tax balances deserve extra attention, because the Trust Fund Recovery Penalty can make owners and responsible officers personally liable for withheld taxes the business failed to pay over. If your CP504B involves Form 941 periods, talk to a professional before you call the IRS.
Conclusion
A CP504 gives you roughly 30 days to fix the problem on your terms, and the IRS’s own 2025 numbers show it follows through when people don’t respond.
