How Shopware sales tax works
What Shopware does
Shopware calculates tax from rates and rules you set by country, state, zip code, or zip code range. For the US, Shopware's docs say its complex tax systems can only be mapped in a practicable way by external tax services, which plug in as tax providers at checkout.
Where it stops
Shopware's tax settings stop at calculation: its US guide has you check which state has which rate, and its tax docs don't cover filing or remitting returns.
What Kintsugi adds
Kintsugi plugs in as your Shopware tax provider: its tax engine calculates sales tax at checkout in real time, and the same data drives nexus monitoring, registration, filing, and remittance.
