Frequently Asked Questions

Do I need to collect sales tax if I sell on Amazon or Shopify?

It depends on your state registrations and where your customers are located. Amazon collects and remits sales tax in most states as a marketplace facilitator, but Shopify stores typically require you to handle your own sales tax obligations. Once you establish economic nexus in a state (usually $100,000 in sales or 200 transactions), you must register and collect. We help you determine where you have nexus and manage all filings.

How do I track cost of goods sold (COGS) for my online store?

COGS should include the direct cost of products sold — purchase price, shipping to your warehouse, and any prep fees. Proper inventory tracking is essential for accurate profit reporting and tax filing. We set up bookkeeping systems that automatically reconcile your platform sales data with your inventory costs.

What business structure should I use for my e-commerce store?

Most online sellers start as a sole proprietor or single-member LLC. As income grows, an S-Corporation election can significantly reduce self-employment taxes. We review your numbers and recommend the right structure based on your actual revenue and long-term goals.

How do I handle taxes if I sell internationally?

International sales may trigger VAT registration requirements in foreign countries, and any foreign income must be reported on your U.S. return. If you use overseas suppliers or have foreign accounts, additional FBAR and FATCA reporting may apply. We handle international tax compliance so nothing falls through the cracks.
