Privacy and AI Data Governance for Tax Documents

Use AI on Tax Documents Without Handing Over the SSN EIN & Pvt Data.

Tax Sanitizer finds the sensitive data in tax documents, such as Social Security numbers, EINs, account numbers, addresses, and dates of birth, and removes or encrypts it before the document goes anywhere: to a preparer, to cloud storage, or into an AI model. You keep the usefulness of the document and lose the risk.

Why It Exists

The Problem.

Every tax document is a complete identity kit. Sending it to an AI model, a shared drive, or an email thread is a breach waiting for a date.

0

Sensitive Values Exposed

What leaves the document is what a model or a reviewer needs. Identifiers stay encrypted with you.

100%

Of the Numbers Intact

Income, deductions, and totals survive sanitizing, so the document still works for analysis and prep.
