# Adds support for parking tax registration types in the US ## What’s new Adds two new registration types for US tax registrations: [parking_tax](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia#tax_registration_create-country_options-us-parking_tax) and [mass_transit_parking_tax](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia#tax_registration_create-country_options-us-mass_transit_parking_tax). Specify these types using the [country_options.us.type](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia#tax_registration_create-country_options-us-type) parameter when you [create a tax registration](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia). Each registration type accepts a [jurisdiction](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia#tax_registration_create-country_options-us-parking_tax-jurisdiction) parameter that takes a FIPS code to identify the specific taxing jurisdiction. ## Impact You can now register to collect and remit parking taxes and mass transit parking taxes in applicable US jurisdictions using [Stripe Tax](https://docs.stripe.com/tax.md). Use the `parking_tax` or `mass_transit_parking_tax` type along with the appropriate jurisdiction FIPS code when [creating a registration](https://docs.stripe.com/api/tax/registrations/create.md?api-version=2026-07-29.dahlia) for these tax types. ## Changes #### REST API | Parameters | Change | Resources or endpoints | |
