What Is IRS Form 15674?
IRS Form 15674 is a concise authorization form allowing taxpayers (individuals or entities) to consent to the IRS disclosing tax return information—defined under Section 6103(b)(2) as data from filed returns, including income, deductions, and credits—to designated parties, typically for closing agreements or appeals. It limits disclosure to essentials like legal name, principal business address, country of residence for treaty purposes, agreement effective date, and any failure to timely pay, preventing broader leaks. Unlike general power of attorney (Form 2848), Form 15674 is narrowly tailored for disclosure in specific IRS proceedings.
Key features:
- Limited Scope: Disclosure confined to agreement-related details; no full return copies.
- Irrevocable for Purpose: Valid until the agreement’s resolution; revocable only in writing.
- Corporate Focus: Primarily for businesses entering closing agreements under Section 7121.
The March 2025 revision (Catalog No. 95646S) introduces optional electronic submission and clarifies treaty-related disclosures. Download the PDF from IRS.gov/pub/irs-pdf/f15674.pdf.
