Tax Services for Ecommerce Businesses
Specialized tax preparation and compliance for ecommerce sellers, online retailers, and digital product creators. From sales tax nexus to 1099-K reporting and inventory accounting, we help you navigate the complex tax landscape of online selling.
Ecommerce Tax Complexity
Selling products online creates tax obligations that traditional businesses rarely face. Between economic nexus laws in nearly every state, varying sales tax rates across thousands of jurisdictions, 1099-K reporting from payment processors, and the intricacies of inventory accounting, ecommerce sellers operate in one of the most tax-complex environments in small business.
Platforms like Shopify, Amazon, Etsy, and eBay each report seller data differently. Fees, refunds, and adjustments complicate revenue reconciliation. Sales tax collection is often handled at the platform level but not always accurately. Our team helps you cut through the complexity and file with confidence.
Key Tax Considerations for Ecommerce Sellers
Multi-state selling creates multi-state tax obligations.
Sales Tax Nexus
Economic nexus laws require out-of-state sellers to collect sales tax once they exceed state-specific thresholds. We help identify where you have nexus and manage compliance across all applicable states.
1099-K Reconciliation
Payment processor 1099-Ks report gross payment volume, not net income. We reconcile these forms against your actual revenue, subtract fees and refunds, and ensure accurate income reporting.
Inventory Accounting
Proper cost of goods sold (COGS) calculation is essential. We help you choose between FIFO, LIFO, and average cost methods and ensure your inventory valuation is IRS-compliant.
Shipping & Fulfillment
Shipping costs, fulfillment fees, and FBA storage charges have specific tax treatments. Understanding what is deductible and how sales tax applies to shipping is critical for accurate reporting.
Multi-State Income Tax
If you have physical presence in multiple states through inventory storage or offices, you may have multi-state income tax filing obligations. We manage apportionment and state filing requirements.
Platform Fees & Adjustments
Marketplace fees, advertising costs, subscription charges, and refund adjustments all affect your taxable income. Proper categorization ensures you claim every deductible expense.

Ecommerce Tax FAQ
How do I handle sales tax for online sales across multiple states?
Sales tax nexus rules vary by state. If you have inventory stored in a state, exceed economic thresholds, or use fulfillment centers like FBA, you may be required to register and collect sales tax. We help determine your nexus obligations.
What is a 1099-K and how does it affect my taxes?
Payment processors issue 1099-K forms reporting your gross payment volume. The IRS threshold for 2026 is $5,000 in gross payments. This form captures total revenue before fees, refunds, and adjustments, so your actual taxable income may differ.
Should I use cash or accrual accounting for my ecommerce business?
Cash basis is simpler and often preferred by small ecommerce businesses. Accrual basis may be required if you carry inventory or have gross receipts above $30 million. We help you choose the right method and maintain consistency.
How do I deduct inventory and product costs?
Cost of goods sold (COGS) includes product purchase price, shipping in, packaging, and direct labor. You can use methods like FIFO, LIFO, or average cost. Proper inventory tracking is essential for accurate COGS calculation.
