Form Validation · W-8 / W-9 / Self-certification

Every form right the first time.

W-8BEN, W-8BEN-E, W-9 and CRS self-certifications validated field-by-field the moment they’re submitted. Catch the six mistakes we see most before you ever accept the document.

The problem

An invalid form is a liability you accepted

A W-8 with a missing treaty claim or an expired signature isn’t just paperwork — it’s a documentation gap that surfaces at exactly the wrong time. Label validates each form against current IRS and OECD rules at submission, so only clean documents enter your records.

How it works

Validate at submission, not at deadline

  1. 1

    Submit

    Investor completes a digital W-8, W-9 or self-certification.

  2. 2

    Validate

    Every field checked against current rules instantly.

  3. 3

    Guide

    Errors flagged inline for the submitter to fix on the spot.

  4. 4

    Accept

    Only clean, valid forms enter your records — with expiry tracked.

The forms that reach our team are already clean. Validation moved upstream, and our remediation backlog basically disappeared.
