Bank-Grade Security Architecture

Security & Data Protection

How Taxamba safeguards taxpayer data, PII, and financial documents with IRS Pub 4557 compliance.

AES-256 Encryption

All Social Security Numbers (SSN), Employer Identification Numbers (EIN), and income values are encrypted at rest using AES-256 bit military-grade encryption keys stored in isolated hardware security modules.

IRS Pub 4557 & FTC Safeguards

Strict adherence to IRS Publication 4557 security standards for tax return preparers, including immutable audit logging, multi-tenant database isolation, and perimeter threat detection.

Multi-Factor Authentication (MFA)

Enforced MFA via TOTP authenticator apps (Google Authenticator, 1Password) and SMS tokens to prevent unauthorized account access.

Isolated S3 Document Vaults

Tax document uploads (W-2s, 1099s) are stored in encrypted AWS S3 buckets accessible only via short-lived, presigned URL tokens.
