Define the release decision
A verified year-end packet must remain available through filing and any later inquiry without turning a laptop or sync folder into the only recoverable copy.
Create a bounded encrypted archive while keeping editable working files, credentials and recovery material separate.
Run the control sequence
- 01Test the current software release with fictional tax records on the supported Windows environment.
- 02Import only manifest-approved files and verify plaintext copies are not left in temporary folders.
- 03Lock, reopen and compare file counts and selected checksums with the source manifest.
- 04Store a separately controlled recovery copy and keep credentials away from the archive media.
- 05Record archive identifier, software version, custodian, recovery location and next test date.
Preserve enough evidence
Record the tax packet identifier, tax year, source device or system, export date, manifest, responsible custodian, authorized preparers, key location, encryption environment, recovery result, retention rule and next review date. Do not put passwords, recovery secrets or unnecessary taxpayer values in the decision record.
Keep the manifest, custodian, approved recipient, key-separation decision, restore result and retention owner together without copying taxpayer values into the record.
Keep surrounding controls visible
An encrypted archive does not replace endpoint security, provider permissions, a separately stored backup or a tested recovery method.
Tax preparation can create extra copies on tablets, laptops, removable media, synchronization folders and recipient devices. The archive owner must address those copies separately and verify the current software release before relying on product behavior.
Questions to ask
Should the archive password travel with the tax packet?
No. Send the archive and its credential through separate approved channels, and verify the preparer before release.
Does encryption make the tax packet accurate?
No. Encryption restricts file access; it does not validate amounts, deductions, classifications or filing eligibility.
