Common reasons for receiving an IRS LTR6018-b Notice

You may receive an LTR6018-b Notice for various reasons. Here are some common scenarios:
  • You granted a tax professional or another third-party service permission to access your tax information. This authorization may have been for filing your taxes, checking your IRS account, or other tax-related services.
  • The IRS is reviewing existing authorizations to confirm their validity. These routine checks help keep your tax records secure.
  • Your tax professional might have changed affiliations, such as moving to a different firm, prompting the IRS to verify the third-party access details.
  • The IRS could not verify the authorization due to incomplete or outdated information. In such cases, the IRS wants to confirm that you still want the listed third party to have access.

Pro Tip

Set up IRS account alerts online to get real-time notifications on any changes to your tax return or account. This helps you stay updated on adjustments and due dates.

How does the IRS LTR6018-b Notice affect you?

An LTR6018-b Notice serves as a reminder to verify the third-party access to your tax information. While it does not mean that your data has been exposed, it is important to review the notice carefully to ensure the security of your tax account.

Verifying third-party access

The notice allows you to confirm whether a third party, such as a tax professional, should continue to have access to your account. If you recognize the authorized party listed in the letter, no further action may be required. However, if you do not recognize the name or did not authorize access, you will need to notify the IRS to revoke the authorization.

Potential consequences of not responding

Ignoring the LTR6018-b Notice can result in the IRS retaining third-party access to your tax account, even if it is unauthorized. This could pose a risk to your personal information. Additionally, failing to respond may lead to further IRS communications or actions, such as additional reviews or limitations on your account.

Impact on your tax account

Responding promptly ensures that your account is up-to-date and helps prevent any unauthorized parties from accessing your tax records. The IRS will not take any adverse actions based solely on the issuance of this notice, but non-response could lead to future complications.

Pro Tip

Use multi-factor authentication for your IRS online account to add an extra layer of security, ensuring that your tax information remains protected from unauthorized access.

Steps to take when you receive an IRS LTR6018-b Notice

Upon receiving an IRS LTR6018-b Notice, follow these steps to ensure a prompt and accurate response:
  • Review the notice thoroughly: Read the letter carefully to understand the reason for the notice and any instructions. The letter will list the name of the third party whose authorization is being reviewed.
  • Verify your records: Check your records to confirm whether you have authorized the listed party to access your tax information. If you have a tax professional, consult them to confirm that the authorization is accurate.
  • Respond according to your situation: If you recognize the authorization, you can call, write, or fax the IRS to confirm. If you do not recognize the name or did not authorize access, check the “I did not authorize” box on the form and return it to the IRS. Make sure to include a clear explanation if needed.
  • Submit your response: Mail or fax your completed response to the IRS within 30 days. If you prefer to fax, use a secure method and understand the privacy policies of any digital fax service you may use. A timely response helps prevent delays and ensures your account stays protected.
  • Keep records: Retain a copy of the notice, your response, and any correspondence with the IRS. These documents may be important if you need to refer back to the situation later.

Pro Tip

Keep a copy of all correspondence with the IRS, including notices and your responses. This will help if you need to reference previous communications or dispute any future issues.

Consequences of not responding to the IRS LTR6018-b Notice

Ignoring the LTR6018-b Notice can result in continued third-party access to your tax account, even if the access is no longer authorized. Here’s what could happen if you don’t respond:
  • Unauthorized access: If you fail to act, the IRS will assume the listed third party should continue to have access to your tax records, potentially exposing your sensitive information.
  • Delayed resolution: Not responding may lead to further IRS notices or require additional documentation to resolve access issues later.
  • Potential future issues: Ignoring the notice could lead to unauthorized changes to your tax records or difficulties in resolving future tax matters.

Pro Tip

Consult a certified tax professional if you have questions about the LTR6018-b Notice or other IRS communications. A professional can provide guidance to ensure your response is accurate and timely.

How to protect your tax account from unauthorized access

Ensuring the security of your tax information goes beyond responding to IRS notices. Here are some additional steps you can take:

Monitor your IRS account regularly

Log in to your IRS account to monitor the status of your authorizations and track any changes to your tax information. Regular account checks can help you detect unauthorized access early.

Use multi-factor authentication

When setting up an online IRS account, use multi-factor authentication to add an extra layer of security. This requires a secondary verification method, such as a text message or email, to confirm your identity.

Limit the sharing of your tax information

Only share your tax information with trusted professionals and authorized individuals. Make sure any tax professional you work with is properly certified and affiliated with a reputable organization.

Regularly update your contact information

Keep your contact information up to date with the IRS. If your address, phone number, or email changes, notify the IRS as soon as possible. This ensures you receive important notices and communications promptly.
