The End of the State Invoice? 7 Myths and Facts About What Really Changes
Debunking 7 myths about the end of the state invoice and what actually changes with the National NFS-e under the Tax Reform.
Executive Summary
One of the most alarmist narratives about the Tax Reform is that “the state invoice is going away” or that “ICMS will disappear.” This claim is partly correct — and the rest is a mix of fact and exaggeration that breeds confusion. This post separates seven myths from facts about what really changes for the invoice with the introduction of the National NFS-e and the replacement of ICMS by IBS.
Context: What Is Actually Changing
Before dismantling the myths, it is worth understanding what LC 214/2025 effectively establishes:
- ICMS formally continues to exist until 2032, but will be progressively replaced by IBS
- ISS formally continues to exist, but will also be replaced by IBS
- The National NFS-e is created as a unified system to replace the state and municipal electronic service invoice systems
- The goods invoice (NF-e) continues to be issued at the federal level (now simply called NF-e, without “state”)
The confusion stems from the fact that “state invoice” can mean two different things:
- NF-e (Electronic Goods Invoice): a continuation of today’s electronic invoice, operated by each state’s tax authority (SEFAZ), but evolving.
- NFS-e (Electronic Service Invoice): it will be national and standardized, replacing the municipal ISS systems.
MYTH 1: “ICMS will end and states will lose all their revenue”
Myth — but with nuance
What happens:
- ICMS does not end immediately. LC 214/2025 provides for a transition period until 2032, when IBS will be fully operational.
- During the transition, ICMS continues to be charged, but with rates converging toward national standards.
- IBS will gradually replace ICMS, but the distribution of IBS keeps a share for the states.
What is not true:
- States will not lose all their revenue. The distribution of IBS preserves a share for the destination entities, so a state like São Paulo, a major consumer, continues to receive tax.
- Exporting states (those that produce more than they consume) will lose relative revenue — but this is partly offset by the transition mechanisms.
The full truth:
States with a strongly producer profile may face significant adjustments during the transition, which is why the compensatory mechanisms and federative governance remain at the center of the debate.
Verdict: Myth — ICMS does not end overnight, and states do not lose all their revenue.
MYTH 2: “The state service invoice will end in 2026”
Myth
What the legislation establishes:
The National NFS-e will be introduced gradually:
- 2026: Companies with annual revenue above R$ 10 million begin to adopt it
- 2027: Companies above R$ 1 million per year
- 2028: All companies
Until 2028, the old systems remain valid. There is no abrupt end.
What is true:
- The migration will be gradual — those not ready in 2026 will not be fined immediately
- There will be a period of coexistence between the old systems and the new one
- Full obligation only arrives in 2028
Verdict: Myth — the transition will be gradual, not abrupt.
MYTH 3: “With the National NFS-e, you no longer need a municipal registration”
True with nuance
What happens:
The municipal registration (which today identifies the company before the city hall for ISS purposes) loses relevance for issuing invoices, because the National NFS-e will use the CNPJ (company tax ID) as the main identifier.
What is still needed:
- The municipal registration is still required for other purposes (licenses, permits)
- Some city halls still require municipal registration to issue local NFS-e (while the systems are not yet integrated)
- Construction companies or those issuing NFS-e for works still need a specific registration at the city hall
Verdict: Half-truth — municipal registration loses importance for issuing invoices, but is still required for other purposes.
MYTH 4: “The National NFS-e will end the fiscal war between municipalities”
Fact
This is one of the myths that, in this case, is true — and it is one of the goals of the reform.
Why it works:
- Uniform national rates: IBS will have a single rate for each type of operation — there is no longer ISS variation between municipalities.
- Mandatory NBS code: service classification is standardized — there is no longer “service code” variation between municipalities.
- Tax destination: IBS goes to the destination state/municipality of the service — so there is no longer any advantage in luring companies with ISS incentives.
What no longer works:
- A city hall offering lower ISS for a company to set up in the municipality? It no longer works — the tax follows the consumer.
- A state offering ICMS credits for a factory to set up there? It works partly — the destination principle reduces the incentive.
Verdict: Fact — the ISS and ICMS fiscal war should end significantly.
MYTH 5: “Everyone will pay the same tax rate”
Myth
What the legislation provides:
LC 214/2025 establishes uniform national rates for IBS (estimated at 12.4%) and CBS (estimated at 8.8%). But that does not mean everyone pays the same amount of tax.
Why not:
- Different tax base: a company that buys many inputs pays less because it generates more credits
- Sectors with differentiated rates: education, health, and food have specific treatments
- Remaining credits: companies with transition credits have additional benefits
- Simples Nacional: companies under the Simples (simplified tax regime) remain in a differentiated regime
Example:
Two storefront companies in São Paulo, both with revenue of R$ 1 million:
- Tech Solutions (software development): few inputs, much labor → pays more tax
- Metalúrgica ABC (industry): many inputs, generates many credits → pays less tax
Both have the same rate (12.4% IBS) — but the effective amount paid is different.
Verdict: Myth — uniform rates do not mean a uniform burden.
MYTH 6: “With the National NFS-e, you no longer need an accountant”
Serious myth
This is a dangerous myth. The National NFS-e automates invoice issuance — but does not replace accounting work.
What the National NFS-e does:
- Issues invoices with standardized fields
- Automatically transmits to the Federal Revenue Service database
- Calculates some fields automatically
What the National NFS-e does not do:
- It does not replace accounting bookkeeping (ECF, ECD)
- It does not perform tax assessment
- It does not guarantee that the NBS codes are correct
- It does not perform tax reconciliation
- It does not advise on tax planning
- It does not respond to audits
The accountant’s role:
The accountant is the one who ensures the NBS classification is correct, that credits are being generated and used correctly, and that the EFD-IBS is being filed correctly. Technology facilitates issuance — but does not replace professional judgment.
Verdict: Serious myth — the accountant remains essential.
MYTH 7: “The electronic invoice is gone — now everything is digital”
Partial myth
What is true:
The National NFS-e is 100% digital — there is no paper version. The NF-e (goods invoice) has also been digital since 2008.
What is not true:
It is not that the electronic invoice has ended — it is that it is being unified and modernized. What was fragmented (municipal ISS systems, state ICMS systems) is being integrated into a national system.
The real evolution:
- 2008: NF-e is created (100% digital goods invoice)
- 2014: The National NFS-e begins to be discussed
- 2026-2028: The National NFS-e becomes reality
- 2032: The old system (ICMS, ISS) completely replaced
The revolution is not “paper to digital” — that had already happened. The revolution is “a thousand systems to one system.”
Summary: What Really Changes
What to Do: Step by Step for Companies
- Don’t panic: the transition is gradual, not abrupt
- Update your systems: ERP and tax software must support the National NFS-e by 2027
- Train your team: those who issue invoices need to understand the NBS code
- Review contracts: add tax rebalancing clauses
- Consult an accountant: correctly classifying services is a professional responsibility
