ChatGPTAmazon seller tax compliance is complex, spanning federal income tax, state sales tax, self-employment tax, and potentially international VAT. Get it wrong, and you face penalties, interest, and audit headaches. Get it right, and you legally minimize taxes while staying compliant.
This comprehensive 2026 guide covers every tax obligation for Amazon sellers: federal filing requirements, sales tax nexus rules, deductible expenses, international considerations, and record-keeping best practices to stay audit-ready.
Federal Income Tax Obligations
Amazon business income is subject to federal income tax. How you're taxed depends on your business structure. The IRS sets the rules for each, and the pages below are the primary sources rather than a summary of a summary. Confirm your own position with a CPA before filing.
Sole Proprietor (Schedule C)
- Report profit or loss on Schedule C attached to Form 1040
- Pay self-employment tax on net profit
- Quarterly estimated taxes required if owing $1,000+
- Simplest structure, full personal liability
LLC (Pass-Through)
- Default: taxed like sole proprietor (Schedule C)
- Can elect S-Corp status for tax savings
- Limited liability protection
- Same self-employment tax unless S-Corp
S-Corporation
- Pay yourself "reasonable salary" (W-2)
- Remaining profit = distributions (no SE tax)
- Savings depend on the salary and distribution split, so model it before electing
- Usually considered once net profit is high enough to cover the added payroll and filing cost
Sales Tax: Marketplace Facilitator Rules
Amazon is a marketplace facilitator in all US states, meaning they collect and remit sales tax on your behalf for most transactions. However:
What Amazon Handles (Most States):
- ✓ Collects sales tax from customers
- ✓ Remits tax to state authorities
- ✓ Files sales tax returns
- ✓ Covers audit liability for Amazon sales
Your Remaining Obligations:
- Registration: some states still require marketplace seller registration
- Off-Amazon sales: you handle tax for your own website, other channels
- Wholesale/FBM: If you do FBM or wholesale, you're responsible
- Economic nexus: track thresholds if selling multi-channel
Deductible Business Expenses
Every dollar in deductible expenses reduces your taxable income. Common Amazon seller deductions:
Cost of Goods Sold
- Product costs
- Shipping to Amazon
- Customs/duties
- Prep services

Equipment

Record-Keeping Requirements
The IRS sets record retention periods by situation, commonly three years and longer in specific cases, so many sellers keep seven years to be safe. Essential documents:
- Sales records: Amazon settlement reports, invoices
- Expense receipts: all business purchases, credit card statements
- Bank statements: Business checking/savings accounts
- Inventory records: Purchase orders, COGS calculations
- Mileage logs: Business vehicle use
- Home office: Square footage, utility bills
- Payroll records: If you have employees or pay yourself (S-Corp)
