# Adds Tax ID Element support to Customer Sessions ## What’s new Adds the [Tax ID Element](https://docs.stripe.com/api/customer_sessions/create.md?api-version=2025-10-29.preview#create_customer_session-components-tax_id_element) component to [Customer Sessions](https://docs.stripe.com/api/customer_sessions/object.md?api-version=2025-10-29.preview), enabling you to securely collect and save tax identification numbers for your customers. ## Impact You can now use the Tax ID Element to securely collect and display tax identification numbers on the client side. Create a Customer Session that enables the `tax_id_element` component to authorize client-side access to tax ID management for your customers. ## Changes #### REST API | Parameter | Change | Resources
