Tax Calculation Integration

Tax calculation integration automates the determination and collection of indirect taxes (sales tax in the US, VAT in the EU, GST in Australia/India, etc.) for each transaction. Tax rules are notoriously complex: rates vary by jurisdiction (state, county, city in the US), product type (SaaS may be taxed differently from physical goods), customer type (B2B transactions may be VAT-exempt with a valid tax ID), and thresholds (nexus rules determine where you have tax obligations). Manual tax calculation is unsustainable for any application with customers in multiple jurisdictions.

Stripe Tax integrates directly into Checkout Sessions, Invoices, and Subscriptions, automatically calculating the correct tax based on the customer's location and your product's tax code. You enable it by setting automatic_tax: { enabled: true } on the relevant Stripe objects and assigning tax codes (txcd_) to your products that classify them for tax purposes (e.g., txcd_10103001 for SaaS). Stripe determines the customer's location from their billing address, IP geolocation, or the tax location you specify, applies the correct rate, and itemizes the tax on the invoice.

For US sales tax, Stripe Tax tracks your economic nexus obligations by monitoring your transaction volume and revenue per state against each state's threshold (e.g., $100K revenue or 200 transactions in the state). When you cross a threshold, Stripe alerts you that you've established nexus and should register for tax collection in that state. After registering, you add the state to your active tax registrations in Stripe, and it begins collecting tax on transactions in that jurisdiction. For EU VAT, Stripe handles B2C VAT collection at the customer's country rate and supports B2B reverse charge mechanism when the customer provides a valid VAT ID.
