IRS Form 8821: Tax Information Authorization

The IRS is required by federal law to keep your tax information confidential. If you’d like a tax professional, lawyer, or bank loan officer to look at your current or previous returns, you will need Form 8821. This document allows you to authorize a person, corporation, firm, or organization the ability to receive and inspect your confidential information from the designated tax type and year you file for.

What is Tax Form 8821?

IRS Form 8821, Tax Information Authorization, allows a taxpayer to authorize the right of any person or company to review their personal tax information from prior returns. The official IRS Form 8821 is a single page document and can be used to grant permission to any type of tax filing for any given year. It can also be used to revoke prior tax information authorizations.

When Can I File Form 8821?

There are many circumstances in which you might want to grant permission for a third party to review your taxes, such as when you’re applying for a mortgage. However, it’s important to know the time limits placed on the different types of requests used on tax Form 8821.

If you are authorizing access to your confidential information for a reason that does not address a tax matter with the IRS (such as income verification,) there is a period of 120 days by when the IRS must receive the form. If the IRS receives Form 8821 more than 120 days after the date of the taxpayer’s signature, they must submit a new form.

If the reason for submitting Form 8821 does address or resolve a tax matter with the IRS, that 120-day requirement no longer applies. For example, if you hire a tax advocate to correct a mistake on your return that is flagged by the IRS, you have more than 120 days from the signature date to submit Form 8821.

What is the Difference Between Form 8821 and Power of Attorney?

It’s easy to confuse tax Form 8821 with Power of Attorney because they both grant third party access to your private information. However, there are many important distinctions between the two. Unlike Power of Attorney, Form 8821 does not give the appointed individual or company permission to make decisions on your behalf.

The designee of Form 8821 is not allowed to:

  • Speak on your behalf
  • Disclose your information to another third party
  • Advocate your position in regard to federal tax laws
  • Execute waiver, consents, or closing agreements in your place
  • Represent you in any other manner in front of the IRS
  • Appoint another party as your authorized third party
  • Negotiate your tax refund check
  • Receive your refund check via direct deposit

Whereas a Power of Attorney Form could allow the appointed third party to act on your behalf by setting up an IRS online payment agreement or seeking tax abatement services, for example, Form 8821 prohibits any action other than the right to view confidential information. Additionally, an 8221 tax form will expire after the designated period is over, while a power of attorney must be explicitly revoked.
