How do I prepare my Amazon seller books for tax season?
The most important task is reconciling your Amazon settlements to your bank deposits. Amazon doesn’t send you gross sales. They send the net amount after deducting fees, refunds, and other charges. Your bank shows one deposit, but behind that deposit is a mess of transactions you need to untangle. Many e-commerce sellers skip this step and end up with inaccurate profit margins because they recorded net deposits as revenue instead of breaking out the components.
Download your Amazon settlement reports for the entire year from Seller Central. These reports show every transaction, fee, and adjustment that makes up each deposit. Your accounting software should track gross revenue separately, then record FBA fees, referral fees, storage fees, advertising costs, and refunds as distinct expense categories.
Inventory is where most Amazon sellers struggle at tax time. You need to calculate cost of goods sold, which means tracking what inventory you started with, what you purchased during the year, and what you had left at year end. If you use FBA, pull your inventory reports from Seller Central and match them to your purchase records. Beginning inventory plus purchases minus ending inventory gives you COGS. Get this wrong and you either overpay taxes or trigger audit flags.
Gather your 1099-K from Amazon. The gross amount on the 1099-K should match closely to what you recorded as revenue for the year. If there’s a significant difference, something went wrong in your bookkeeping and you need to find the discrepancy before filing. The IRS receives a copy of that 1099-K and will notice if your reported revenue doesn’t align.
Sales tax has gotten simpler since Amazon now collects and remits in most states as a marketplace facilitator. But you still need records of what was collected and where, especially if you sell through other channels or have nexus in multiple states from inventory stored in FBA warehouses.
Get your books to your accountant at least a month before you want to file. Give them clean financial statements, your 1099-K, settlement report summaries, and your inventory calculations. If you hand over a login to messy books and expect them to figure it out, you’ll pay for the cleanup in accounting fees.
If your books aren’t in good shape right now, consider getting help from Scottsdale bookkeeping services that understand Amazon accounting. The settlement reports and inventory tracking are specialized enough that generic bookkeeping often misses important details that affect your tax liability.
