Permanently Immutable.
Audit-Proof Forever.
WORM (Write Once, Read Many) technology is the backbone of the TaxFort vault. Once marked as final, documents are locked from any modification or deletion for a minimum of 10 years. Even we cannot touch them.
The WORM Lock Advantage
Non-Erasable
Files in the Final folder are stored with Object Lock compliance which prevents anyone, even the root administrator, from deleting them.
Versioned History
Non-locked source files maintain a complete version chain. Every change is tracked, and old versions are always retrievable for auditors.
10-Year Default Retention
We enforce the industry-standard 10-year retention policy for all tax documents by default, exceeding IRS Publication 583.
Compliance-Mode Object Lock
This document has been frozen at the hardware level. The retention period expires on March 10, 2036.
Unbreakable Security Architecture
Why top practices are moving to immutable-first environments.
SEC 17a-4(f) Compliant
Meets or exceeds the strictest storage compliance requirements from SEC and IRS.
Deduplication Check
Verifies hashes before locking ensures you only store and lock unique versions.
Multi-Region Archive
Locked documents are replicated across different geolocations for disaster recovery.
Zero Deletion Policy
Under no circumstances can final documents be removed before their retention expires.
Instant Verify
Built-in checksum verification ensures document integrity every time it's accessed.
Audit Trail Ready
Full metadata logs for every lock event, providing a clear chain of custody.
