Single Sign On (SSO) with Okta

Read about how to configure SSO with the identity provider, Okta.


Single Sign On (SSO) allows users to sign in once across multiple applications, sites and platforms.

Taxamo have created an integration with Okta, an identity provider for SSO. Taxamo acts as a service provider, storing the users from your merchant's account with Okta.

For more information about Okta, see logged out from

This has the following benefits:

  • Role assignments are done in Okta.
  • Security is optimized because Taxamo (as the service provider) stores all the user information with Okta (the identity provider). This means that Taxamo cannot see your users' data.
  • Single LogOut (SLO) is also implemented. This allows users to log out from the identity provider (Okta) by logging out of the service provider (Taxamo).

Two types of login are possible after you complete the configuration:

  • Service Provider (SP) initiated: This is when a user logs in using the Taxamo dashboard. This requires the Organization ID and a login through Okta.
  • Identity Provider (IdP) initiated: This is when a user logs in using the Taxamo app in Okta.
