Navigating U.S. tax obligations as an Amazon seller can be daunting—corporate tax, federal income tax, state sales tax, Nexus requirements, and more. This guide breaks down everything you need to confidently sell on Amazon in 2025.

1. Taxes for U.S.-Registered Companies on Amazon

Registered in the U.S.? Here’s what you’ll pay:

  • Federal Corporate Income Tax: 15–35%, filed annually
  • State Corporate Tax: 4.5–12% (some states like NV, WA, SD, WY have 0%)
  • Local Taxes: Vary by municipality
  • Payroll Tax: Withheld from employee wages
  • Business Privilege Tax: Charged by local governments
  • Sales Tax: Consumer-paid, remitted by seller. Rates range from ~5.4% to 12% (states like OR, DE, NH, and MT have no sales tax)

2. Understanding U.S. Sales Tax

Sales tax is collected from buyers and remitted by sellers, with filing periods ranging from monthly to semi-annually. Any Amazon seller with a physical presence (“nexus”) in a state must register, collect, and remit sales tax in that state, with rates typically between 5.4–12%.

3. How to Register and Remit

Traditionally, sellers must obtain a U.S. EIN and sales tax permits for each applicable state. Without these, selling may lead to severe penalties.

However, if you're using Amazon FBA, Amazon automatically collects and remits sales tax in states where it has fulfillment centers. You still manage tax settings but avoid handling remittances directly.

For FBM sellers, obtaining sales tax permits and remitting yourself—or outsourcing—is essential.

4. Which Products Are Taxable?

For FBA sellers, Amazon manages this entirely.

FBM sellers need to know taxable categories: essentials like groceries, magazines, prescription medication, and digital media may be exempt in some states. Most other products are taxable.

5. Tax Obligations for Taiwan-Based Companies

  • U.S. Income Taxes: Taiwan companies don’t pay U.S. corporate, state, or local income taxes just by selling via Amazon in the U.S..
  • Taiwan Income Taxes: Apply only when profits are repatriated to Taiwan (e.g., via Payoneer transfer to Taiwan). Keeping funds abroad for overseas expenses or services typically defers Taiwanese income tax.

6. Sales Tax Calculations for FBM

FBM sellers automatically charge combined state and local sales tax for each transaction, typically around 2.9%—unless shipping to a state with no sales tax.

7. Nexus & Tax Reporting Process

Post-June 2018, any U.S. nexus (e.g., inventory in a warehouse, office, employee, etc.) mandates sales tax remittance in that state.

Amazon Seller Central → Reports → Payments → Tax Reports allows you to generate filing-specific data.

Recommended states:

  • Delaware: No state corporate tax; ideal for larger companies
  • Wyoming: No franchise or state corporate tax; great for small businesses
