Form 8821 (sp): Tax Information Authorization, Spanish Version
Form 8821 (sp) is the Spanish version of Form 8821, Tax Information Authorization. The one-page PDF is in Spanish under the title "Autorización para Recibir Información Tributaria" and is dated January 2021 ("enero de 2021", Rev. 1-2021). The IRS made it for taxpayers who read Spanish. The agency name, the labels inside the IRS-use-only box and a few footer items are printed in English.
A taxpayer uses it to name one or more designees who may inspect and/or receive the taxpayer's confidential tax information for the types of tax, form numbers, years or periods and matters listed on line 3. The top of the form says not to use Form 8821 (sp) to request copies of tax returns or to authorize someone to represent the taxpayer, and not to sign it until every applicable line is complete.
The PDF points to www.irs.gov/Form8821sp for its instructions. The instructions cited on this page are the English Instructions for Form 8821. The English edition, Form 8821, has its own page. You can fill out this Spanish PDF free in your browser on this page and download it without an account.
What's on Form 8821 (sp)
Line 2: designees
Two blocks for a designee's name and address, CAF number, PTIN, phone and fax, a box to send them copies of notices, and boxes for a changed address, phone or fax.
Line 3: tax information
Four columns: (a) type of tax information, (b) tax form number, (c) years or periods and (d) specific tax matters, plus a box for access through an intermediate service provider.
Lines 4 and 5: specific use and prior authorizations
Line 4 is a box for a specific use not recorded on the Centralized Authorization File (CAF). Line 5 is a box to keep earlier tax information authorizations in place.
