- Jurisdictions: United States

## When to use it

Use when a taxpayer will let a named individual, corporation, firm, organisation or partnership inspect or receive confidential tax information for listed types of tax and periods, or will revoke an earlier tax information authorisation. Do not use it to appoint a representative before the IRS.

## Used for these tasks

- [Build a document index for an ATO audit or review response](https://ailawframework.com/practice/taxation/build-a-document-index-for-an-ato-audit-or-review-response.md)

## How AI may be used

The tool may list which line 1 to line 3 facts are still missing from a lawyer's checklist, and it must not enter any name, year or tax matter that will be written on the form.

**AI may:**

- List whether line 1, the designees, the line 3 columns, and the line 5 retention choice are still blank on the lawyer's checklist
- Remind the lawyer that a new authorisation revokes earlier ones unless line 5 is used, and that the opened extract shows no perjury declaration

**AI must not:**

- Must not type or draft any name, tax type, form number, year or specific tax matter that will appear on Form 8821
- Must not add a penalty-of-perjury sentence. The opened extract does not contain one
- Must not sign the form or certify that a signer has legal authority
- Must not treat Form 8821 as Form 2848 or as permission to represent the taxpayer

**The lawyer checks:**

- The about page says Form 8821 authorises any individual, corporation, firm, organisation or partnership to inspect or receive confidential information, verbally or in writing, for the type of tax and the years or periods listed, and to delete or revoke prior authorisations
- The about-page PDF link is labelled 0121 Form 8821. The instructions link is labelled Instructions for Form 8821 (09/2021). The opened PDF extract does not print a revision line. Do not add "Rev. January 2021" from the Form 2848 header
- Line 1 says the taxpayer must sign and date on line 6. More than two designees: attach a list. There is a checkbox for access via an Intermediate Service Provider. Line 3 columns are type of tax, form number, year or period, and specific tax matters
- The words "Civil Penalty" on line 3 are a type of tax information, not a perjury warning. The opened extract contains no perjury declaration
- If the line 4 box is not checked, the IRS revokes all prior tax information authorisations unless the line 5 box is checked and copies of the authorisations to retain are attached. Revoking without a new authorisation is in the line 5 instructions, which were not opened
- Line 6: if a corporate officer, partner, guardian, partnership representative or designated individual, executor, receiver, administrator, trustee, or other individual signs, that person certifies legal authority for the line 3 matters and periods. An incomplete, unsigned or undated form is returned. Do not sign a blank or incomplete form
