At a Glance: Understanding Your CP501 Notice
What it means
How serious is it
What to do next
Look for any issues with your CP501 notice:
- Do you agree with the amount the IRS claims you owe?
- If you disagree, you have the right to dispute the IRS.
- Do you have the means to pay the full amount?
- If paying in full would create a financial hardship, you may qualify to settle the debt for less than the full amount. You may also qualify for a payment plan.
- Is this your first time receiving a tax penalty?
- You may qualify to eliminate some of those penalties through the first-time penalty abatement program.
If you agree with the balance due and have the means to pay it, paying as soon as possible will help you avoid additional interest and penalty charges.

CP501 Notice Example

CP501 vs. CP14
CP14 Notice is the initial notice informing a taxpayer of a balance due, typically sent after the tax return is processed. It provides the tax year affected, the amount owed, and instructions for payment or dispute, serving as the first step in resolving the tax debt.
CP501 Notice acts as a follow-up reminder with a more urgent tone, reiterating the debt and warning of more penalties or collection actions if the tax debt is not addressed.
CP2501 vs. CP501
With only a one-digit difference, it can be easy to confuse the IRS Notice CP501 and CP2501. However, they are completely different notices issued by the IRS. CP2501 Notice is sent when there is a tax return discrepancy and one or more items do not match what was reported. It is also not a bill and only requires you to confirm the information or provide an explanation with supporting documents if you disagree.
On the other hand, the CP501 Notice is an urgent balance-due reminder that requires immediate action on your outstanding tax bill. If ignored, the IRS will add more penalties and may soon begin aggressive collection actions.
Resolving Your IRS Notice CP501
Read your IRS Notice CP501 carefully, as it should answer your initial questions. It will tell you your due date, amount due, and offer payment options for your tax debt. You must make your payments by the due date to avoid additional penalties and interest.
If you cannot pay the bill in full, there are options available to arrange a payment plan or potentially settle your tax debt for less than the full amount if you qualify.

IRS Notice CP501 Already Paid
The IRS issues notice CP501 when you don’t respond to the initial balance due notice (CP14). However, if you have already paid the amount owed or have made payment arrangements with the IRS, you can safely disregard this notice, unless the remaining balance is for penalties and interest accrued between the time you received the CP14 notice and the time you made your payment.
Remember to keep this notice for your records with proof of payment or payment plan arrangements. If there are any mistakes in your CP501 letter, you can contact the IRS directly to review your account.
Can I Dispute CP501 Notice?
Yes, you have the right to dispute your CP501 Notice if there are any mistakes or if you disagree with what the IRS claims you owe. If you decide to dispute this letter, it is important to take action immediately before the printed deadline.

IRS Tax Scams: Red Flags to Look for
IRS tax scams have become increasingly sophisticated, targeting unsuspecting taxpayers through various channels using fear tactics and false claims about immediate tax debts. The IRS officially communicates via physical mail and will never initiate unexpected contact with aggressive demands or threats.
Some red flags to watch for include:
- Impersonators with fake IRS identification numbers.
- Unsolicited calls demanding personal financial information
- Requests for personal information through social media, text messaging, or email.
When in doubt, we recommend contacting the IRS through their official channels to verify any claims about your tax status.
