Tax return redaction is the removal of return information from a federal filing protected under IRC §6103 (26 U.S.C.). That section guards a taxpayer's identity and figures from disclosure. anonym.plus marks each identifier on your device, so the form reads cleanly while protected data goes.
When this applies
A return states the filer's SSN, address, and dependents on the first page. You strip that protected information before the copy leaves your office.
How anonym.plus handles it
- Open the filing in anonym.plus on your device.
- Local OCR reads a scanned or printed copy.
- The tool flags the SSN, ITIN, name, and address.
- Confirm each flag and keep the line totals.
- Mask the SSN or swap it for a label.
- Save the clean copy locally.
What you need to provide
- The filing (PDF, scan, or DOCX).
- An operator: Mask keeps only the last four of an SSN.
- Optional allow-list for the tax year you must cite.

Limitations & cautions
Section 6103 protects return information broadly, including indirect clues. The tool flags named items; a unique figure can still hint at a filer. Review the schedules before you share.
Frequently asked questions
What does IRC §6103 protect on a filing?
It protects return information — a taxpayer's identity, the figures reported, and data the IRS holds. anonym.plus flags those identifiers so you can apply the rule.
How much of the SSN may stay?
Often only the last four digits, depending on the recipient. The Mask operator keeps those four and hides the rest in one pass.
Is the copy sent to a server?
No. The app is fully offline. The filing and its data never leave your device.
