E-commerce businesses based in NJ face unique bookkeeping and tax challenges that traditional service businesses do not: multi-state sales tax nexus and economic thresholds, marketplace facilitator rules (where Amazon or Etsy collects tax on your behalf), inventory and cost of goods sold tracking, and reconciling platform payouts that arrive days or weeks after the sale with fees, refunds, and chargebacks deducted. Greg Monaco, CPA helps NJ e-commerce businesses set up bookkeeping systems that handle these complexities from the start.
E-commerce businesses based in NJ face unique challenges: multi-state sales tax obligations, marketplace facilitator rules, inventory tracking, and platform-specific payment timing.
How Do Multi-State Sales Tax Rules Apply to NJ E-Commerce Businesses?
If you sell to customers in other states and exceed their economic nexus thresholds (typically $100,000 in sales or 200 transactions), you must collect and remit sales tax in those states. Tools like TaxJar or Avalara can automate this.
How Do Marketplace Facilitator Rules Affect NJ E-Commerce Sellers?
If you sell through Amazon, Etsy, or similar platforms, the marketplace is generally responsible for collecting and remitting sales tax on your behalf. But you still need to track these amounts for bookkeeping and ensure they’re not double-counted.
How Should NJ E-Commerce Businesses Track Inventory and COGS?
E-commerce businesses must track cost of goods sold, the cost of the products you sell, including materials, shipping to you, and direct labor. Proper COGS tracking is essential for accurate profitability reporting and for your tax return.
How Do I Reconcile E-Commerce Platform Payouts in My Bookkeeping?
Amazon, Shopify, and other platforms don’t pay you immediately. Reconciling platform payouts to your bank deposits requires understanding the timing difference, fees, refunds, and chargebacks. I help e-commerce sellers and content creators who sell digital products navigate this reconciliation process.
What NJ Sales Tax Obligations Apply to E-Commerce Businesses?
NJ requires you to collect sales tax on taxable goods sold to NJ customers. Even if you sell primarily through marketplaces that handle collection, you need to file NJ sales tax returns if you’re a registered seller.
Key Takeaway
The two biggest tax compliance issues for NJ e-commerce businesses are multi-state sales tax obligations (triggered when you exceed $100,000 in sales or 200 transactions in another state) and accurate COGS tracking for inventory-based businesses. Automated sales tax tools like TaxJar or Avalara handle the first issue; proper inventory accounting in QuickBooks handles the second. Both should be set up from day one.

Frequently Asked Questions
Do NJ e-commerce businesses need to collect sales tax in other states?
Yes, if you exceed another state's economic nexus threshold, typically $100,000 in sales or 200 transactions, you must register, collect, and remit sales tax in that state. Tools like TaxJar or Avalara automate multi-state compliance.
Does Amazon handle sales tax for NJ sellers?
Amazon is a marketplace facilitator in all states that require sales tax collection, so it collects and remits sales tax on your behalf for sales made through its platform. However, you still need to track these amounts for bookkeeping and ensure they are not double-counted on your returns.
How do I track cost of goods sold for an e-commerce business?
COGS includes the cost of products you sell: materials, inbound shipping, and direct labor. Track beginning inventory, purchases during the year, and ending inventory. COGS equals beginning inventory plus purchases minus ending inventory. QuickBooks or similar software can automate this.
Do I still need to file NJ sales tax returns if I sell only through marketplaces?
Yes. Even if the marketplace collects and remits NJ sales tax on your behalf, NJ may still require you to file sales tax returns as a registered seller. The returns may show zero tax due, but the filing obligation remains.
