Have you received an IRS notice letter and do not know what to do?  Here are some helpful tips that will allow you to confirm that the notice letter is not a scam and decipher if action is required on your part.

Confirm that an IRS Notice is not a scam.
The unfortunate reality of today’s world is that fraud and scams are prevalent. This is why it is important to demonstrate due diligence for any requests that require you to provide confidential or financial information.  If you receive an IRS notice letter, it is important to first confirm that the letter is in fact from the IRS.  You can do this by inputting your IRS notice letter number in the IRS notice search feature that is located on the IRS's website. 

What action is required on my part?
Not all notices require action.  Some notices are sent to simply confirm an online registration or a recent address change.  These notices are sent as a precautionary measure on the IRS’s part to combat fraudulent tax return filing.  The only time you would have to take action for this kind of notice is if the information provided in the notice is incorrect.  A few notices that do not always require action are provided below.


CP148A and CP148B Notices

  • Sent to confirm that a new business address.

CP301 Notice

  • Sent to confirm that you registered for an IRS online services account.

CP188 Notice

  •  Sent to communicate that your refund is being held until it is determined that you owe no other taxes. 

Most IRS notices do require action on your part, so it is always important to carefully read over the notice letter once you have verified that it is from the IRS.  The notice letter will provide specific instructions for the action that you will be required to take to avoid penalty charges.   


Receiving a letter from the IRS can be unnerving, but know that regardless of what kind of notice you receive, the IRS provides resources and assistance for resolving discrepancies.  You also have the right to appeal notices.  The key to avoiding large consequences from the IRS is being proactive and taking immediate action because the IRS does not go away.
