CP504 Notice: What to Do When the IRS Sends This Letter Checklist

disqualified employment tax levies, or pursue federal contractor levies without sending another notice.

Wage garnishment and bank account levies require a different notice before the IRS can proceed with those actions. The IRS must send a separate final notice called an LT11 or Letter

1058 before those enforcement actions can begin.

Automated procedures through the IRS Automated Collection System generate the CP504 rather than individual Revenue Officers handling your case. You have approximately 30 days from the notice date to respond, pay the balance, request a payment plan, or appeal the proposed collection action.

Who Should Use This Guide

This guide applies to you if

• You received a CP504 notice in the mail showing an unpaid tax balance.
• The notice lists a tax year and amount you either dispute or cannot pay immediately.
• No wage garnishment or bank account freeze has occurred.
• You want to explore payment options or challenge the amount before further IRS action.

This guide does not apply to you if

• An LT11 or Letter 1058 has already arrived, which is the formal final notice of intent to

levy that carries Collection Due Process hearing rights.

• Active wage garnishment or a bank account levy is currently in place.

• Unpaid payroll tax debt involving withheld employee taxes makes you a business owner

facing specialized employment tax issues.

• An approved IRS payment plan is already in effect, and the CP504 arrived as a default

notice.

Critical Decision Points

Responding within 30 days of the notice date printed on your CP504 is the most important factor in protecting your rights. Missing this deadline allows the IRS to seize your state tax refund immediately and proceed to the next collection phase without further warning.

Time begins counting from the date the IRS mailed the notice, not the date you received it.

Filing a payment plan request or requesting a Collection Appeals Program appeal before the deadline temporarily pauses certain collection actions.

Action Steps

1. Locate your CP504 notice and verify all information shown, including the tax year, tax type, and amount owed. Call the IRS at 1-800-829-1040 immediately if any detail appears incorrect.

2. Find the response due date printed on the notice and mark it clearly. This deadline is typically 30 days from the issue date shown on the letter.

3. Gather proof of any payments you have already made on this debt. Collect payment receipts, bank statements, or IRS letters showing previous payments applied to this balance.

4. Determine whether you dispute owing the debt or simply cannot pay it. If you dispute the amount, you may request a Collection Appeals Program appeal by following the instructions on your notice.

5. Review your current income and monthly expenses to determine what you can realistically pay. The IRS uses a specific formula for necessary living expenses when evaluating payment plans.

6. Contact the IRS Automated Collection System by the response due date. Call

1-800-829-1040 or use IRS.gov to initiate a payment plan or request an appeal.

7. Request the Currently Not Collectible status in writing before the deadline if you cannot afford any monthly payment. This status temporarily pauses collection action while you rebuild your finances, but the debt remains, and interest continues to accrue.

8. Request a Collection Appeals Program appeal in writing before the deadline if you believe the IRS made an error. The CP504 notice provides information about requesting this type of appeal.

9. Keep a written record of every call you make to the IRS, including date, time, the representative's name, and what was discussed. IRS customer service representatives sometimes fail to document calls correctly, and your notes become critical proof if your case escalates.

10. Request written confirmation of any payment plan approval before making your first payment. Do not rely on verbal agreements.

11. Check your mail weekly until you receive written confirmation of your request. If you do not receive confirmation within 45 days, call the Automated Collection System again and request a new ticket number.

12. Set a calendar reminder 30 days before any approved payment plan's first due date. A single missed payment can restart collection action and trigger the levy authority.

Common Mistakes

Waiting to respond because you assume the notice will go away moves your case automatically toward state refund seizure and issuance of the formal final notice. Sending a payment without a letter explaining what it covers allows the IRS to apply the funds however they choose, often to the oldest debt first, rather than the balance shown on your CP504.

Ignoring the CP504 and responding only after you receive an LT11 or Letter 1058 means you missed the earlier opportunity to resolve the debt before formal enforcement proceedings began. Calling the IRS and verbally agreeing to a payment amount without requesting written confirmation leaves you with no proof if the IRS later denies that the agreement existed.

Consequences of Inaction

The IRS will seize your state tax refund within 30 days if you do not respond to the CP504. After that action, the IRS will send an LT11 or Letter 1058, which is the formal final notice of intent to levy that provides Collection Due Process hearing rights under Internal Revenue Code Section

6330.

Once you receive that formal final notice, the IRS can proceed with wage garnishment, bank account levies, and seizure of other property if you do not request a Collection Due Process hearing within 30 days. Revenue Officers may become involved at later stages, depending on case complexity and the amount owed.

When to Seek Professional Help

Obtain professional representation if you received the CP504 more than 20 days ago and have not contacted the IRS. Hire a tax professional or attorney if you dispute the debt and have evidence such as tax return discrepancies or proof of prior payment.

Seek immediate help if the IRS has assigned your case to a Revenue Officer who is requesting an in-person financial interview. Professional assistance becomes critical if you cannot afford any monthly payment and need to request the Currently Not Collectible status or propose an

Offer in Compromise to settle the debt for less than the full amount owed.
