Tax inside a payment platform
Stripe Tax calculates and collects sales tax, VAT and GST on Stripe transactions. Registration and filing need Tax Complete, a one-year plan, and are done by Stripe in some countries and by partners elsewhere.
Choose Stripe Tax if you’re one of these:
Kintsugi is free to start and charges per filing (Free monitoring; Starter is $75 per registration or filing). Kintsugi charges for each registration and return, so the bill grows with every state and filing. Stripe Tax charges 0.5% per transaction (Tax Basic; Tax Complete from $90 a month on a one-year contract). That price covers every state and country you sell into. Having one US state’s returns filed costs $75 per filing with Kintsugi. Filing is optional with Stripe Tax: one US state filed for you costs $430 a month.
