IRS Pub 4557

Safeguarding Taxpayer Data

GLBA

Safeguards Rule

SOC 2

Type II

SEC 17a-4

Records Retention

The Problem

Tax season runs on chasing documents

Firms lose hours every week tracking down client files across email threads, consumer file-sharing apps, and a separate tool for every signature — with sensitive taxpayer data scattered across all of them.

The Patchwork Approach

  • Documents requested and returned over plain email
  • A separate, add-on tool for every e-signature
  • No single record of who accessed which client file
  • Taxpayer PII sent without scanning or controls
  • Manual reminders and status spreadsheets

The MnemoShare Approach

  • Secure forms collect documents in one place
  • Built-in e-signature — no bolt-on subscription
  • One immutable audit trail across every client
  • DLP scanning detects taxpayer PII automatically
  • Automated reminders and real-time tracking
Use Cases

Common accounting & tax workflows

Client Document Collection

Collect tax documents, financial statements, and supporting records with secure web forms and request lists — clients upload directly, with reminders and real-time tracking instead of endless email chasing.

Replaces: Email attachments, consumer file-sharing tools

Engagement Letters & Approvals

Send engagement letters, authorizations, and sign-offs for built-in e-signature — clients sign online, and every signature is captured with a complete, tamper-evident audit record.

Replaces: Print-sign-scan, separate e-signature add-ons

Deliverable & Return Delivery

Deliver completed returns, financials, and advisory packages through a secure client portal — encrypted end to end, with confirmation of exactly who downloaded what and when.

Replaces: Unencrypted email, mailed paper copies

Third-Party & Advisor Exchange

Exchange working papers and financials with lenders, auditors, attorneys, and the client's other advisors — identity-bound access and audit logging on every transfer.

Replaces: SFTP, shared drives, cloud folders

Compliant Client Notifications

Send secure-message and document notifications from your firm's own domain, with DLP scanning that flags taxpayer PII before it leaves — keeping client communication on-brand and protected.

Replaces: Plain email, BCC sprawl, generic no-reply senders
