How do I handle sales tax for my Amazon business?
Amazon handles most sales tax collection automatically. Every state with sales tax has marketplace facilitator laws that require Amazon to calculate, collect, and remit sales tax on orders placed through their platform. For the majority of your transactions, the tax obligation is taken care of without you doing anything.
That doesn’t mean you can completely ignore sales tax.
If you use FBA, Amazon stores your inventory in fulfillment centers across multiple states. Having inventory physically located in a state creates nexus, which is a tax connection that may require you to register with that state’s department of revenue. Even though Amazon collects the tax on your behalf, some states require sellers to file returns showing marketplace-facilitated sales. These returns might show zero tax due because Amazon already remitted it, but you still need to file them.
The tricky part is that Amazon moves your inventory around based on demand. Your products might sit in a warehouse in Texas one month and get redistributed to Ohio the next. This means your nexus footprint shifts without you doing anything intentional. Tracking where your inventory goes requires pulling Amazon’s inventory reports regularly and understanding which states trigger obligations.
Registration requirements differ by state. Some require registration once you exceed certain sales thresholds. Others want you registered as soon as you have physical presence through inventory. Getting this wrong leads to penalties, especially if a state audits your business and discovers you should have been registered years ago.
On the bookkeeping side, you need to record sales tax correctly in your accounting software. Amazon’s settlement reports show tax collected on your behalf, but that money flows through your disbursements before Amazon remits it to the states. If your books don’t separate sales tax from revenue, your income looks inflated and your financial statements are misleading. E-commerce accounting requires understanding how Amazon’s reports translate into proper journal entries.
B2B sales create another consideration. If you sell to businesses that provide resale or exemption certificates through Amazon’s Tax Exemption Program, you may need to maintain records of those certificates. The documentation requirements can still fall on you as the seller even when Amazon facilitates the transaction.
Working with Scottsdale bookkeeping services that specialize in sales tax can simplify this significantly. Someone who understands Amazon seller accounting can track your nexus, manage state registrations, file required returns, and make sure your books reflect sales tax correctly. The cost is typically less than the penalties for non-compliance or the hours you would spend trying to navigate it yourself.
