Arkansas Sales Tax Nexus: Thresholds & CPA Steps

Introduction

Arkansas was an early adopter of economic nexus enforcement following Wayfair and maintains a relatively straightforward sales tax compliance framework. However, marketplace facilitator rules and local tax considerations require careful CPA oversight.

This guide outlines Arkansas nexus thresholds, registration requirements, filing obligations, and practical CPA advisory steps.

What Creates Sales Tax Nexus in Arkansas?

Physical Nexus

Physical presence includes:

• Offices, warehouses, or retail locations

• Inventory stored in Arkansas

• Employees or service activity in the state

Economic Nexus

Remote sellers may establish nexus without physical presence.

Affiliate and Marketplace Nexus

Affiliate relationships and marketplace activity can create collection obligations.

Economic Nexus Thresholds in Arkansas

A seller establishes nexus if it has:

• $100,000 or more in gross Arkansas sales, or

• 200 or more separate transactions

Either threshold independently creates nexus.
