Your Sales Tax reports will show your total taxable sales and sales tax collected for each state you have set up for tax collection in Seller Central.
Currently, Amazon will only collect AND remit the sales tax for the states listed in this article from Amazon.
This will reflect as the Marketplace Facilitator Tax in the "Other" area of your Profit & Loss and in the Marketplace Facilitator Tax Collected section on the Reports>Sales Tax Report page.
This report breaks down the following information:
Total Taxable Sales - the dollar amount of taxable sales
Total Sales Tax Collected - the total sales tax collected from your taxable sales
Total Marketplace Facilitator Tax - the amount of sales tax Amazon collected and automatically remitted to the IRS on your behalf
Total Sales Tax Refund - the sales tax amount refunded to the buyer due to a return (This amount is negative since it is refunded to the buyer.)
Total Marketplace Facilitator Tax Refund - the amount refunded to the seller due to a return (Since Amazon remitted this amount to the IRS on your behalf previously, they refund this back to your account. This should then be offset by the sales tax refunded back to the buyer.)
You can change the view to specify a preset date range, based on Daily, Weekly, Monthly, Quarterly, or Yearly.
