What expense category is Amazon Marketplace US?
Amazon's US third-party e-commerce marketplace for buying and selling products — commonly used to source event supplies, merchandise, or office goods.
Amazon Marketplace US enables businesses to purchase or sell products through Amazon's platform. As a business expense, charges here typically represent product purchases (event supplies, decorations, equipment, or general merchandise) rather than a service fee. Sellers may also incur monthly Professional plan fees ($39.99/month) or per-transaction referral and fulfillment fees. The tax treatment depends on what was purchased — supplies are operating expenses, while equipment may be capitalizable. The 'Event expenses' category suggests purchases of event-related items.
How businesses classify Amazon Marketplace US
Tax details
- Save the Amazon order confirmation for every purchase — the IRS requires documentation of what was bought and its business purpose, not just the credit card statement.
- If you purchased equipment over $2,500 through Amazon Marketplace, reclassify it as a capital expenditure subject to depreciation or Section 179.
- For event-related purchases (decorations, supplies, branded merchandise), document the event name, date, and business purpose to substantiate the deduction.
- Amazon Marketplace seller fees (referral fees, FBA fees, monthly plan) are fully deductible as ordinary business operating expenses under IRC §162.
- Separate personal and business purchases on your Amazon account, or use a dedicated business account, to avoid commingling and audit risk.
