Form 8821-SP is the Spanish‑language version of IRS Form 8821, Authorization to Disclose Tax Information. It lets a taxpayer grant a third party permission to receive confidential tax return data from the IRS.
Plain English
Think of this form as a written permission slip. You sign it so an accountant, attorney, or other representative can look at your tax records without you having to hand over the actual returns. It does not give the representative power to act on your behalf, only to see information.
