Jurisdictions

A jurisdiction is a lowercase code used to group and filter Check's tax-related resources geographically. It is either fed (federal) or a lowercased ISO 3166-2:US region code — essentially the two-letter state code, lowercased.

Two things to keep in mind:

• Local taxes use their state's code. A Pennsylvania borough's Local Services Tax has a jurisdiction of pa, so filtering taxes or agencies by jurisdiction=pa returns that state's state and local entries together.
• The format is designed to extend internationally. Non-US jurisdictions prefix the country, e.g. ca_qb for Québec, Canada. Today the catalog is US-only.

For how jurisdictions relate to taxes and agencies, see the Taxes, Agencies, and Jurisdictions guide.
