01. OVERVIEW

The Registration of Service Providers of Other Municipalities (CPOM) was an initiative of the prefectures of several Brazilian states in order to guarantee the correct payment of the service tax (ISS) in typical cases in which the provider has a CNPJ in a municipality other than where the service will be provided. This measure aims to combat tax evasion practiced by some companies that use fictitious addresses to pay less taxes.

How this evasion works:

By the Complementary Law no. 116/03, ISS must be collected at the service provider’s establishment (rule that includes numerous exceptions). The municipalities have the autonomy to define the ISS rate between 2% and 5%. Some business owners, in face of this fact, register companies in addresses from municipalities where the rate is lower than that of the municipality where the business is actually established.

02. EXEMPLIFIED CONCEPT

With CPOM in force, the provision of services is now subject to ISS double taxation. We are talking specifically about the following scenario: 

• City A - 2% ISS rate
• City B - 5% ISS rate
• Service provider’s CNPJ - City A
• Service contractor’s CNPJ - City B

Prefecture of city B requires CPOM

03. PROCESSES

Accounts Payable

• Current ISS withholding operational flow:

• ISS withholding operational flow for CPOM:

As from the Supplier Municipality Verification event (yellow circle), due considerations will be made in the Tax module, in the ISS Double Taxation Registration. Both taxes (both the service provider and the service contractor's) will be calculated and withheld in the Financial module when the Accounts Payable bill is issued. For the ISS withholding on the bill post (parameter MV_MRETISS = 2), this functionality has not yet come into effect.

• How it works in the System (simple ISS double taxation scenario):

MV_MRETISS = 1
MV_ALIQISS = 2

Nature Registration

Supplier Registration

ISS Double Taxation Registration (this will include, by type of service, Service Providers - Suppliers that are from other municipalities and that do not have CPOM for the municipality where the Accounts Payable invoice is being issued)

ISS Rate Registration (also enter, in this registration, the Supplier that represents the Municipality responsible for paying ISS double taxation). It is not necessary to bind a product

Addition of Accounts Payable for BRL 10,000.00, in which BRL 200.00 is ISS

When saved, the routine validates the scenario:

By filling the ISS Serv Code field with the type of service previously registered to calculate the ISS double taxation
