Where do Amazon seller fees go on Schedule C?

Updated October 10, 2026 路 Schedule C, Line 10
Short answer Schedule C, Line 10 Commissions and fees

Amazon seller fees belongs on Line 10, commissions and fees.

Why line 10

The referral fee Amazon keeps on each order, usually 8 to 15 percent of the item price, is a selling commission and belongs on line 10. Amazon reports gross proceeds, so the fees must be deducted on their own line instead of netted out of sales. Fulfilment by Amazon charges are a different category: pick, pack, ship and storage are fulfilment costs, and the goods themselves are Part III cost of goods sold.
