Step 0: Client Onboarding Questions
Before proceeding with any West Virginia sales tax analysis, collect the following from the client: [T1]
| # | Question | Why It Matters |
|---|---|---|
| 1 | Do you have a West Virginia sales tax registration / tax ID? | Determines whether registration is needed before filing. |
| 2 | What is your current filing frequency (monthly / quarterly / annually)? | Controls which return periods to prepare. |
| 3 | What is your nexus type -- physical presence, economic nexus, or both? | Determines registration obligations and applicable rules. |
| 4 | Are you a marketplace seller (selling through Amazon, Etsy, etc.)? | Marketplace facilitator may already be collecting on your behalf. |
| 5 | What types of products or services do you sell in West Virginia? | Drives taxability classification under West Virginia law. |
| 6 | Do you sell to exempt entities (government, nonprofits, resellers)? | Determines whether exemption certificates must be collected and retained. |
| 7 | Do you have locations, employees, or inventory in West Virginia? | Physical presence creates nexus independent of economic thresholds. |
| 8 | Do you sell into multiple West Virginia local jurisdictions? | Local tax rates vary; determines compliance complexity. |
If the client cannot answer questions 1-4, STOP and gather this information before proceeding. [T1]

EC3 -- Broad Service Base Impact on Compliance [T2]
