Service Exports Under the Tax Reform | VMAHUB
The tax reform changes the rules for service exports. Understand the impact on CBS, tax credits and the NBS Schedule — regardless of your sector.
Executive Summary
Brazil’s Tax Reform, driven by LC 214/2025 — which establishes the IBS and the CBS — brings profound changes for every company that exports services: technology, consulting, design, agribusiness, education and other sectors. The new system preserves the core principle of not taxing exports, but it completely reshapes the mechanics of crediting, the classification of services rendered abroad and the ancillary obligations. For any Brazilian company that bills in foreign currency, the landscape tends to be more favorable than the current one in several respects — but it demands heightened attention to NBS classification and the safekeeping of supporting documentation. This guide explains, with concrete examples from the technology sector, what changes and how to prepare, whatever your sector may be.
How Service Exports Are Treated Under IBS/CBS
The rules below apply to any company that exports services — whether a software house, a strategy consultancy, a design studio, an agribusiness firm providing technical consulting abroad, or an education platform with students in other countries. The practical examples use the technology sector because it is the most representative, but the reasoning is the same for all.
The non-cumulative principle and exports
One of the reform’s major promises is the transition from a cumulative system to a non-cumulative one. In practice, this means each tax applies to the value added at each stage — and does not accumulate in a cascade as happens today with ISS levied on top of ISS.
For service exports, the benefit is direct: the idea is that the exported service leaves the Brazilian tax chain free of accumulated indirect tax. In practice:
- CBS: On service exports, the treatment seeks to remove the domestic incidence of CBS, preserving the neutrality of the transaction for the Brazilian provider.
- IBS: For IBS, the logic is similar: if consumption occurs abroad, the transaction generates no incidence in Brazil.
This model follows the international logic recommended by the OECD and already partly adopted by countries such as Mexico and Chile. For the Brazilian technology company, the export transaction tends to become cleaner from a tax standpoint.
Crediting on service exports
One point deserves attention: even without CBS/IBS incidence on the export, the company may hold credits for taxes paid in earlier stages of the production chain.
Practical example:
VertixTech is a Brazilian company from São Paulo that develops custom software for clients in the United States. Its inputs include:
- Cloud servers (AWS) — contracted from a US company, paid in dollars
- Development tool licenses (JetBrains, GitHub)
- Salaries of developers in Brazil
- Office in São Paulo (rent, electricity, internet)
Today, VertixTech pays ISS on the full value of the service invoice, and can deduct only a minimal fraction of credits. With the reform, the flow changes:
- Domestic inputs (office, electricity) generate IBS/CBS credits that can be used to offset the tax owed on other transactions.
- The services provided to the US company are classified as a service export and leave free of CBS/IBS.
- Any remaining credits may be the subject of a refund request to the federal government.
In typical market simulations, the net result tends to be a reduced tax burden for exporting technology companies, depending on their input profile.
Classifying Services: The Role of the NBS
One of the greatest practical challenges for technology companies during the transition is the correct classification of the exported service under the Brazilian Services Nomenclature (NBS).
The NBS is the new classification system that will replace the current municipal ISS lists. Each service has a specific code, and the difference between one code and another may mean a distinct tax treatment or even a change in the place of incidence.
Why does this matter for technology exports?
The NBS has a specific section for technology services:
- 6201 — Custom software development (made to order)
- 6202 — Off-the-shelf software licensing
- 6203 — Information technology consulting
- 6204 — Technical support and systems maintenance
- 6205 — Data processing and hosting services
Each code has its own rules about the place of incidence. For exports, codes 6201 and 6202 are particularly relevant — and the analysis must confirm whether the customer or the end user is located abroad.
Classification example:
DataSafe Cloud offers backup and cloud storage services for companies in Brazil and abroad. It needs to classify:
- Storage for a Brazilian client: code 6205, IBS applies in the state where the client is located.
- Storage for a US client: code 6205, classified as an export, with no IBS/CBS incidence in Brazil.
The company needs systems that can identify, at the moment the NFS-e is issued, whether the customer is in Brazil or abroad — because the tax classification depends on that information.
Compliance Obligations for Technology Exporters
The National Electronic Service Invoice (National NFS-e)
With the reform, the National NFS-e comes into operation — a standardized tax document for all of Brazil. For service exports, this is a significant improvement:
- The export NFS-e will have specific fields to indicate the destination of the service (Brazil or abroad).
- Filling in the NBS code will be mandatory.
- Numbering will be centralized (no longer by municipality).
The transition to the National NFS-e begins in 2026 and will be gradual. By 2028, all municipalities are expected to be integrated into the national system.
Supporting documentation for exports
A critical point: a company that exports services must keep documentation proving that the service was in fact rendered abroad. This includes:
- Signed contracts with overseas clients (with certified translation, if necessary)
- Communication records (emails, support tickets) showing performance abroad
- Proof of payment by international clients
- System access logs showing use by users abroad
Without this documentation, the Receita Federal (Federal Revenue) may challenge the export classification — and the company could lose the tax benefit, on top of being subject to penalties.
Document retention period
The legislation requires five years of retention for documents that prove the export. This is especially important because, under the new system, a credit refund may be requested for up to five years after the transaction.
Step by Step: How the Exporting Company Should Prepare
- Map your international client base: identify all contracts with overseas customers and classify them by type of service (NBS).
- Review your contracts: include clauses that evidence the performance of services abroad (place of execution, customer’s address, proof of the client’s tax residence).
- Update your invoicing systems: make sure the ERP system can issue an NFS-e with a destination field (export) and the correct NBS code.
- Train your billing team: the team that issues invoices needs to understand the difference between selling software to a Brazilian client and exporting services.
- Run a remaining-credits assessment: before the full transition, map which credits the company is entitled to use or claim back.
- Consult a specialist: every company has a different cost structure — the impact of the reform can vary considerably.
Concrete Example: A Brazilian Software House Exporting to the US
BrazilaSoft is a company from Joinville (SC) that develops made-to-order e-commerce platforms for clients in the US. It currently bills BRL 5 million per year, with 80% from exports.
Current scenario (ISS + IRPJ + CSLL):
- ISS on exports: 5% of the value (municipal minimum), but with difficulty crediting
- IRPJ + CSLL on profit: ~34% of net profit
- Estimated effective burden: ~28% of revenue
Post-reform scenario (IBS + CBS + IRPJ + CSLL):
- CBS: estimated rate of 8.8% of the value, with a zero rate for exports
- IBS: estimated rate of 12.4% of the value, with a zero rate for exports
- IRPJ + CSLL: maintained, but on a cleaner calculation base (fewer cumulative costs)
- Estimated effective burden: ~22% of revenue (a reduction of ~6 percentage points)
The 6-percentage-point difference represents savings of roughly BRL 300,000 per year for BrazilaSoft — resources that can be reinvested in R&D or in hiring more developers.
Common Mistakes to Avoid
- Don’t mix domestic and export transactions in the same contract: this creates complexity in NBS classification and can lead to assessments.
- Don’t forget to update the CNPJ (company tax ID) with the Receita Federal: companies that export must have export activity registered with the Federal Revenue.
- Don’t issue an NFS-e as a domestic transaction when it is an export: the NBS code for exports is different — using the wrong code is an infraction.
- Don’t fail to keep supporting documentation: the lack of documentation is one of the main causes of tax assessments at exporting companies.
What Lies Ahead
LC 214/2025 provides for a transition period running until 2032, when the old system (ISS, IPI, PIS, COFINS) will be completely replaced by IBS/CBS. For exporting technology companies, the time to prepare is now — the sooner a company adapts to the new NBS classification and the new NFS-e procedures, the smoother the transition will be.
