Presidential candidate Flávio Bolsonaro (PL) has pledged to abolish the split payment system, the automatic tax withholding mechanism established by Brazil's tax reform. The proposal drew an immediate pushback from Deputy Treasury Minister Dario Durigan, who argued that opposing the system amounts to "favoring tax evaders."
The dispute has thrust a highly technical policy into the center of the presidential runoff campaign, scheduled for October 25, 2026. It pits the current administration's focus on tax simplification and anti-evasion measures against the opposition's argument that the system threatens corporate cash reserves.
- What it is: The automatic splitting of taxes at the moment a purchase is paid.
- The clash: Flávio Bolsonaro wants to scrap the system; Dario Durigan argues it prevents fraud.
- The impact: Companies lose the grace period to remit taxes, tightening working capital.
For equity investors and business owners alike, the split payment is much more than bureaucratic jargon. It fundamentally changes how quickly cash leaves corporate accounts and reaches the government, directly impacting working capital.
What Is the Split Payment?
The split payment is a new method for collecting consumption taxes created by the tax reform: the federal Goods and Services Contribution (CBS), and the Goods and Services Tax (IBS), which is managed by state and municipal governments.
The name comes from English and literally means dividing a payment. In practice, the mechanism prevents companies from holding onto tax revenue in their cash reserves to pay the government the following month.
This system was already established in the constitutional amendment that created Brazil's dual VAT and has since been regulated by the reform's supplementary law. Its operational implementation by the national financial system remains the final step.
How Does the Split Payment Work in Practice?
The division of funds is carried out entirely in an automated fashion by banks, card processors, and payment institutions, which cross-reference transaction data with the operation's electronic invoice.
Imagine a hypothetical sale of R$ 100, where R$ 25 corresponds to the sum of the new taxes (CBS and IBS). Under the current model, the merchant receives the full R$ 100 in their account and has a grace period before remitting the R$ 25 to the government.
Once the split payment takes effect, the division happens directly at the card terminal or e-commerce payment gateway, routing the funds to their respective destinations instantaneously.
The R$ 25 tax portion does not pass through the company's checking account. Instead, it goes straight to Brazil's federal tax authority and the IBS management committee, minimizing the risk of tax default.
Why Has the Mechanism Become a Political Battleground?
The debate heated up after candidate Flávio Bolsonaro publicly advocated for ending the split payment, arguing that immediate tax withholding harms the financial health and liquidity of Brazilian micro and small businesses.
Conversely, Deputy Treasury Minister Dario Durigan pushed back against the proposed cancellation, stating that the split payment represents a crucial technological leap for the country and that opposing the system means siding with tax evaders.
The government maintains that automation eliminates the unfair advantage of competitors who sell goods more cheaply simply because they fail to pay their taxes at the end of the month.
Companies continue using tax funds temporarily as working capital, but default risks and complex enforcement remain high.
The government secures real-time collection, driving tax evasion down near zero, but forces companies to seek alternative short-term financing.
What Changes for Companies and Investors?
The main pain point for businesses regarding the split payment is the loss of the financial float—the period during which tax money sits in a company's account earning yield or being used to pay suppliers.
Many retail and service companies use this timing mismatch as an interest-free credit line. Without that cushion, they will need to rely on bank loans to cover day-to-day cash flow.
Exchange-listed companies with tight margins and high working capital needs may face additional pressure on free cash flow. Sectors such as brick-and-mortar retail and labor-intensive services will require closer scrutiny when analyzing short-term liquidity.
On the other hand, for large corporations that already operate in full tax compliance, the system could lower compliance costs—such as spending on accountants and systems to calculate tax filings—while accelerating the recovery of tax credits accumulated along the production chain.
What to Watch Moving Forward
The future of the split payment is tied directly to the election results in late October and the next phases of tax reform implementation.
Runoff Election Results — The October 25 vote will determine whether the project stays on its current schedule or faces repeal attempts in Congress.
Bank Adaptation — FEBRABAN and card processors must finalize technological testing to ensure the split does not cause processing bottlenecks during sales.
Transition Rules — Watch for any grace periods or special cash flow accommodations for micro and small businesses under the Simples Nacional regime.
The Rico aos Poucos Verdict
The split payment is a technological reality that will be difficult to completely overturn, given that it is baked into the foundation of the approved tax reform. For investors, the safest approach is to monitor the short-term debt levels of portfolio companies, anticipating which ones will struggle most to operate without the cushion of monthly tax float.
