Amazon FBA sellers face a distinctive tax challenge: inventory can move between fulfilment centres and create obligations in states where the business has no office. A useful tax platform needs to understand both inventory movement and marketplace-collected tax.
What to look for
- Real-time physical and economic nexus monitoring.
- Automated registration, filing, and remittance.
- Pricing that fits transaction volume and product margins.
- Integrations across Amazon, Shopify, eBay, Walmart, and accounting systems.
- Reconciliation that separates sales tax from Amazon fees and settlements.

Why Kintsugi fits Amazon sellers
Kintsugi monitors nexus, classifies products, reconciles marketplace data, and supports registration and filing. Its team combines automated workflows with human help for notices and state-specific questions.
Amazon may collect tax as a marketplace facilitator in many states, but sellers still need to understand where returns, registrations, or other reporting responsibilities remain. Review each state's current rules (our marketplace facilitator laws by state table covers thresholds and seller obligations) and keep marketplace and direct-channel sales distinct.
