Client Onboarding Best Practices Guide

How to onboard a new tax client: engagement letter, document collection, intake questionnaire, GLBA privacy notice, and compliance file setup.

5 stepspractice
1

Send the engagement letter

Provide a written engagement letter that defines the scope of services, responsibilities, fees, and document retention policy. Have the client sign and return before work begins.

2

Collect required documents

Provide a document checklist specific to the client's situation (W-2, 1099, K-1, prior-year return, etc.). Set a clear deadline for submission and confirm receipt of all items.

3

Complete the intake questionnaire

Use a standardized intake form to capture filing status, dependents, deductions, life changes, and prior-year carryovers. This becomes the basis for due-diligence documentation.

4

Deliver the GLBA privacy notice

Provide the Gramm-Leach-Bliley Act privacy notice at the start of the engagement. Document delivery and retain a copy in the client file.

5

Set up the compliance file

Create the client file with all engagement documents, intake records, and a due-diligence checklist. Establish the workflow from intake through preparation, review, filing, and closeout.
