Overview

Understanding Your
Industry's Tax Landscape

The retail landscape changed permanently after the Supreme Court's 2018 Wayfair decision. Online sellers now face economic nexus obligations in states where they have never set foot, maintained inventory, or had a physical presence. For e-commerce businesses selling nationally, this means potential sales tax obligations in 40+ states — each with different rates, exemptions, and filing frequencies.

Common Challenges

Tax & Financial Challenges
Retail & E-Commerce Businesses Face

These are the issues we see most often — and the ones that cost the most when handled incorrectly. Click any item to read more.

Economic Nexus Post-Wayfair — 50-State Exposure+
After South Dakota v. Wayfair (2018), states can impose sales tax based on economic activity alone — no physical presence required. Most states set thresholds at $100,000 in sales or 200 transactions. If you have been selling nationally without collecting sales tax, you likely have significant back liability across multiple states.
Marketplace Facilitator Rules+
Amazon, Etsy, eBay, and other marketplace facilitators collect and remit sales tax on your behalf in most states. But this does not eliminate your direct sales obligations — you still need to track marketplace sales, exclude them from your own nexus analysis, and file returns where you have direct nexus.
Inventory Accounting Methods — FIFO vs. LIFO vs. Average Cost+
The inventory accounting method you choose directly affects your cost of goods sold and taxable income. LIFO can create significant tax deferral during periods of rising costs but requires an IRS election. The right method depends on your product mix, margin structure, and long-term plans.
Sales Tax on Digital Products & Services+
Sales tax on digital products varies dramatically by state. Some states tax all digital goods, some tax none, and some distinguish by product type. If you sell digital products, your nexus and taxability analysis must account for each state's specific rules.
Multi-Channel Inventory & Drop-Shipping Nexus+
Storing inventory in Amazon FBA warehouses creates physical nexus in every state where Amazon places your inventory — potentially 20+ states. Drop-shipping arrangements create additional nexus questions based on supplier location and delivery state.
Use Tax Obligations for Business Purchases+
When you purchase supplies or inventory from out-of-state vendors who do not collect sales tax, you owe use tax in your home state. Most retailers under-report use tax — a common finding in state sales tax audits.
