Enterprise-Grade Security

Compliance & Security
Overview.

We built TaxFort specifically for tax professionals and accounting firms who need enterprise-grade security, immutability, and client data isolation.

Our Commitment to You

All documents are stored with high-level encryption both at rest and in transit. Once a document is marked as final, it becomes non-rewritable and non-erasable, satisfying regulatory requirements for document retention.

01. Data Protection & Encryption

At Rest

All files are encrypted at rest using AES-256 by our primary storage provider, Backblaze B2.

In Transit

All traffic is encrypted in transit using TLS 1.3 via Cloudflare, ensuring no unencrypted data leaves our infrastructure.

02. Immutability & Retention (WORM)

Final documents (filed returns, signed engagement letters, IRS transcripts) are automatically stored in Compliance-mode Object Lock with a 10-year default retention.

Once locked, files are non-rewritable and non-erasable — even we cannot modify or delete them. This provides a true WORM (Write Once, Read Many) audit trail.

Source documents remain fully versioned and editable, with old versions permanently retained for audit trails.

03. Client Data Isolation

Strict Isolation

Per-taxpayer isolation using unique UUID structures ensures no data leakage between clients.

Granular IAM

Accounting firms receive specific IAM access keys that only allow access to authorized clients.

04. AI-Powered Auditability

  • AI automatically sorts and renames uploads into year + category folders
  • Full audit logging of every upload, view, download, and permission change
  • Detailed version history available for every document in the system
  • Instantly searchable metadata for transparency and reporting

05. Compliance Foundation

Infrastructure

Built on Backblaze B2 + JuiceFS, leveraging SOC 2 Type II compliant storage infrastructure.

Regulatory Standards

Designed to support SEC 17a-4(f), IRS Publication 583, and AICPA record retention requirements.

We are preparing for a full SOC 2 Type II report in 2026.
