Forwardable tax brief · Tax-authority CISO

Separate exact-state integrity from acceptance and tax correctness.

Why should I care?

A retained copy can be altered without an independently checkable final state.

What does not need to change?

Keep IAM, monitoring, audit, DLP and security controls.

What can be piloted safely?

One non-confidential verification flow.

UD is proposed as a portable record and provenance layer. This brief does not claim authority integration, filing acceptance, tax correctness, legal sufficiency, compliance or institutional adoption.
