Tax Reform: The Importance of Keeping the Customer Address Correct

In the Tax Reform context, the customer address reported on the invoice becomes a decisive element for the correct incidence of IBS and CBS, serving as the basis for defining the place of consumption and, consequently, the federative entity entitled to collect the tax.

In practice, this data will be used automatically to:

• Determine the place of IBS incidence;
• Cross-validate against national registries and geo-referenced bases;
• Correctly assess the taxes due on the operation;
• Analyze compliance in electronic fiscal cross-checks.

With the implementation of the new model, auditing will heavily rely on automatic data cross-checks, involving the national taxpayer registry, geo-referenced addresses, electronic fiscal documents, and revenue-sharing rules between states and municipalities.

In this scenario, any divergence between the registered address, the actual place of consumption/provision and the official bases can be automatically identified by tax authorities, exposing the issuing company to relevant fiscal risks such as:

• IBS collection for the incorrect state or municipality;
• Tax difference charge by the harmed federative entity;
• Interest and late-payment fines;
• Fines for inaccurate or incorrect invoice information;
• Challenges to the validity of the fiscal operation;
• Denial or dispute of the buyer's tax credits, when applicable;
• Joint liability of the invoice issuer;
• Increased exposure to electronic audits, automatic notifications and infraction notices;
• Need to rectify fiscal documents and open ex officio fiscal proceedings.

It is important to note that, in the new tax model, the issuing company cannot exempt itself from the risk by claiming customer master errors, since the responsibility for correctly issuing the fiscal document and defining the place of tax incidence remains with the supplier.

As a result, the customer address stops being merely operational data and takes on a weight equivalent to CNPJ/CPF in tax relevance, directly impacting fiscal compliance, tax assessment and risk exposure in the IBS and CBS environment.

Considering the importance of correctly maintaining the customer address — and the fact that a company can change its address at any time of the year — no single strategy can guarantee permanent perfection of the master.

In this context, using solutions like MDM+ BRO and MUB enables building a mixed strategy that combines triggers, automations, workflows and human interactions, ensuring high quality and reliability of address information in the customer master:

• During the initial onboarding of each customer, run queries to public bases (RFB, CCC, Simples Nacional);
• Monthly, for customers classified in the A, B and/or C curves, run automated cleansing based on public queries (RFB, CCC, Simples Nacional);
• Since the address can be updated at any time of the year, an effective alternative is to trigger automated cleansing based on public queries from transactional events (ERPs/CRMs/SRMs coupled via events like SAP Business Workflow Event Manager, TOTVS Event Viewer / Audit Trail Triggers) such as the creation of a Sales Order, Delivery or NF-e issuance, ensuring the master information used is up-to-date at the exact moment of the operation. This scenario also allows, in the worst case, generating an alert to interrupt the operation in case of a serious master discrepancy that could not be resolved automatically.

Given the new model introduced by the Consumption Tax Reform, the customer address stops being a simple master data field and becomes a critical attribute of tax governance.

Errors or outdated information in this field can result in undue tax payments, assessments by states and municipalities, fines for incorrect information, credit denial and a significant increase in companies' fiscal exposure.

In this context, relying only on manual controls or one-off validations is not enough. The combination of queries to public bases, automated cleansing, intelligent workflows and automated triggers, enabled by solutions like MDM+ BRO and MUB, allows organizations to adopt a preventive, intelligent posture aligned with the new tax scenario.

Both in the current model and in the IBS and CBS environment, customer address management must become a systemic, integrated and recurring process, allowing companies to reduce fiscal risks, increase master data reliability and ensure greater predictability, safety and compliance.
