A plain-language explanation of common tax-professional identifiers and roles.
Why this matters
Strong businesses and informed taxpayers make better decisions when they have organized information and a repeatable process. PTIN, EFIN, and ERO is not just a one-time task; it connects to training, compliance, operations, and technology.
What to focus on
Start with complete, accurate records instead of estimates or assumptions.
Create a repeatable process so important tasks do not depend on memory.
Review financial, tax, compliance, and operational information together when they affect one another.
Document decisions and keep supporting records in a consistent location.
Ask for professional guidance when the issue requires tax, legal, lending, investment, or other licensed advice.

BRG Firm Practical Action Guide
PTIN, EFIN, and ERO: Understanding the Roles should be approached as building a regulated professional service business, not simply purchasing tax software. A new tax office needs clear responsibilities, secure client intake, documented compliance, training standards, and controls over who can prepare, review, and transmit returns.
What to review
Review PTIN responsibilities, whether an EFIN or ERO relationship is required for the planned model, software access levels, due-diligence procedures, data security, client document handling, e-file authorizations, bank-product procedures when offered, and how preparers are trained before receiving live access.
Common mistakes to avoid
New offices can create unnecessary risk by giving broad software permissions too early, skipping practice returns, failing to document due diligence, or treating an EFIN as if it removes the responsibility of individual preparers and office leadership.
Practical checklist
Define PTIN, EFIN, and ERO responsibilities in writing.
Require training and practice returns before live production access.
Use role-based software and client-data permissions.
Build compliance and security checks into the normal workflow.
