Municipal Inscription Number (IM)

The Municipal Inscription Number (IM) is the taxpayer identification number in the Municipal Tax Register. This registration is required for companies that provide services, and are required to pay the ISS tax to the city.

Companies doing business in multiple cities must have a different IM for each city. Municipal Inscription Numbers of the first party and the third parties are mandatory for tax reporting and service fiscal documents.

For first parties, use the Manage Tax Registrations of Legal Reporting Unit Tax Profiles task to define the Municipal Inscription Number.

Customers, suppliers, and other third parties can use the Manage Tax Registrations of the Third-Party Tax Profiles and Third-Party Site Tax Profiles tasks. This information is validated for uniqueness.
