Turn on Sales Tax Calculations for Session Fees on the Studio Details Area:

Once turned on here, it will follow the sales tax rules configured in your Stripe Account. Stripe has an automatic or manual sales tax calculation feature controlled through your Stripe Dashboard:

Option 1 — Manual Tax Rates (simpler) Go to Dashboard → Products → Tax rates and create your rates there. You can define any number of tax rates and apply them to invoices, subscriptions, and one-time payments. If you work with a small number of rates, this is the easiest approach.

Note that you can't change the percentage, country, or state after you set them — if you need to update those, you'd create a new rate and archive the old one.

Option 2 — Stripe Tax (automated) If you want automated tax calculation where you don't need to define rates yourself, use Stripe Tax instead. It handles rate lookups by address automatically.
