Split payment tax reform: how it works, impacts on cash and how to prepare your company

O split payment tax reform is one of the most important points of the new tax collection logic in Brazil and promises to profoundly transform the way companies deal with taxes, cash flow and financial reconciliation.

If you're a financial manager, CFO or entrepreneur, understanding how the split payment IBS CBS works has ceased to be a technical curiosity and has become a strategic necessity.

After all, this model can have a direct impact on your company's cash flow, reducing the net value received from sales and requiring greater operational control.

What is split payment and why was it created?

O split payment tax reform is a mechanism for paying taxes in installments, in which the amount of taxes is automatically separated at the time of the commercial transaction.

In practice, this means that when a sale is made, the company does not receive the full amount of the transaction. Part of that amount, corresponding to taxes (such as IBS and CBS), is automatically directed to the government, while the rest is credited to the company.

This model has emerged as a solution to a historic problem in the Brazilian tax system: default and the mismatch between tax collection and payment.

Today, in the traditional model:

With the tax split payment, In this way, the government can guarantee tax collection at the time of the transaction, significantly reducing tax evasion.

In addition, the model is aligned with the concept of full non-cumulativeness of IBS and CBS, This allows greater control over tax credits and debits along the chain.

Another important objective is to simplify inspection: As the tax is already withheld at source, the need for complex audits and data cross-checks is reduced.

However, this change has significant impacts for companies, especially with regard to cash flow - a topic we will explore in detail in the next few topics.

Split payment: how does it work in practice?

To understand the split payment how it works, It is important to visualize the flow of a commercial operation within this new model.

Imagine a sale of R$ 1,000 with a tax burden of 25% (hypothetical for teaching purposes). In the current model, the company would receive the R$ 1,000 and then pay R$ 250 in taxes.

In the split payment IBS CBS, the flow changes:

• Customer pays R$ 1,000
• R$ 250 are automatically directed to the government
• Company receives only R$ 750 liquids

This process can be carried out through financial institutions, payment intermediaries or systems integrated with the tax environment.

Another important point is that split payment can operate in different formats, such as:

• Full retention at the time of the transaction
• Partial retention with subsequent adjustments
• Hybrid models with credit clearing

In addition, the system should consider the logic of tax credits. Companies that have accumulated credits can have compensation mechanisms to avoid double payments.

That's why split payment Brazil will not necessarily be uniform for all operations. It may vary depending on

• Type of transaction
• Economic sector
• Tax regime
• Company profile

Another important aspect is integration with billing and ERP systems. In order to work properly, split payment requires tax information to be aligned in real time with financial transactions.

This represents a significant change from the current model, where tax assessment takes place later.

Why is split payment a central pillar of tax reform?

O split payment tax reform 2026 is not just an operational innovation - it is one of the pillars underpinning the new collection model based on IBS and CBS.

The tax reform seeks to create a simpler, more transparent and efficient system. To this end, it adopts the concept of VAT (Value Added Tax), which depends on a well-controlled chain of credits and debits.

In this context, split payments play a key role:

• Ensure collection at the time of the operation
• Reducing defaults
• Increasing fiscal transparency
• Facilitate credit control

Without this mechanism, it would be more difficult to guarantee the proper functioning of full non-cumulativeness.

Another important point is that split payments reduce competitive distortions. Companies that previously didn't pay their taxes correctly were no longer able to compete on an equal footing with those that were up to date. With the new model, this difference tends to diminish.

In addition, the government gains greater predictability of tax collection, which can contribute to fiscal stability.

However, this centralization of collection also transfers part of the operational responsibility to companies, which will need to adapt their systems and processes.

Difference between the current model and split payment

The implementation of tax split payment represents a structural change in the way taxes are paid in Brazil.

In the current model:

• The company controls tax payments
• Greater cash flexibility
• There is a risk of default

As for the split payment model:

• The tax is collected automatically
• The company receives net amounts
• Cash control changes completely

This difference has a direct impact on financial management: Companies that use gross sales to finance operations will need to adapt quickly.

Another important point is predictability: Although the split payment reduces tax risks, it requires greater financial planning, This is because the cash available will be less when the funds come in.

In addition, the new model requires greater integration between areas:

• Tax
• Financial
• Technology

This change reinforces the importance of integrated and strategic management.

Impact of split payments on companies' cash

O split payment tax reform brings one of the most sensitive changes to financial management: the direct impact on cash flow.

This is undoubtedly the point that most worries managers, especially those who operate with tight margins or long financial cycles.

In the current model, the company receives the gross amount of sales and decides when to pay the taxes within the legal deadline.

In practice, this allows a certain cash flexibility, which is often used to finance operations, pay suppliers or even balance periods of low liquidity.

With the split payment IBS CBS, This logic changes completely. As the tax is withheld at the time of the transaction, the company only receives the net amount. This immediately reduces the amount of cash available.

This impact can have important consequences, such as

• Reduction in available working capital
• Greater need for bank credit
• Pressure on payment flows
• Need to review financial planning

In addition, companies that operate with long terms of receipt (such as installment sales) can face a financial mismatch.

In some scenarios, the tax can be collected before the company even receives the full amount of the sale.

Another critical point is the management of tax credits: As the IBS and CBS system is non-cumulative, companies will be entitled to credits.

However, the timing of these credits may not coincide with the cash flow, generating the need to more sophisticated management.

That's why impact of split payment on cash requires a change in mentality. The financial manager will need to act more strategically, with more precise forecasts and rigorous control.

Impact on the receivables cycle and working capital

O split payment also significantly alters the financial cycle of companies, especially with regard to the working capital.

In the traditional model, the financial cycle is made up of three main elements:

• Average collection period
• Average payment period
• Average storage time

With split payment comes a new factor: the automatic withholding of taxes at source, which reduces the net amount received.

In practice, this directly affects working capital, as the company starts to operate with fewer of its own resources. In many cases, it will be necessary to resort to external financing to maintain the same level of operation.

Another relevant impact is the anticipation of receivables: Companies that use tools such as credit card advances may experience changes in conditions, as the net amount available will be lower.

In addition, commercial contracts will need to be reviewed. Companies working with long terms may need to renegotiate conditions in order to balance their cash flow.

The main impacts on the financial cycle include:

• Reduction in immediate liquidity
• Increased dependence on credit
• Need to renegotiate with suppliers
• Review of forward sales policies

Companies that fail to prepare may face operational difficulties, even if they are profitable on paper.

On the other hand, those that adapt quickly can turn this change into a competitive advantage.

Impacts of split payments by type of company

The effect of split payment IBS CBS will not be the same for all sectors. Each type of company will have specific challenges, depending on its business model, margin and cost structure.

Services

Service companies tend to feel the impact more intensely, especially those with a high tax burden and low margins.

As many do not have large volumes of tax credit, The amount retained can represent a significant reduction in available cash.

In addition, service companies often have high operating costs (payroll, rent, etc.), which increases the pressure on cash flow.

Another relevant point is that the service sector may face challenges in pricing, since the reduction in cash may require adjustments to prices in order to maintain profitability.

Retail

In retail, the impact of tax split payment is directly related to the volume of operations and the profit margin.

Companies that work with high turnover and low margins will need strict control to avoid liquidity problems.

On the other hand, retailers can benefit from greater tax predictability, since the tax is collected automatically.

Another important point is integration with payment methods. Since most sales are made by card, split payment can be implemented directly in financial transactions.

Industry

In industry, The impact tends to be more balanced due to the possibility of using tax credits along the production chain.

However, the sector will still face challenges related to cash flow, especially in operations with long terms and high investment volumes.

Industry will also need to adjust its systems to ensure the correct calculation and offsetting of credits.

Practical scenarios of split payment in operation

To better understand split payment how it works, It's worth analyzing a few practical scenarios.

Scenario 1: Direct sales to consumers

A company makes a sale of R$ 1,000 with a tax charge of 25%.

• Customer pays R$ 1,000
• R$ 250 go directly to the government
• Company receives R$ 750

In this case, the impact is immediate.

Scenario 2: Production chain with credits

Supplier sells to industry:

• For sale: R$ 500
• Tax: R$ 125
• Supplier receives R$ 375

Industry sells to retailers:

• Sale: R$ 1,000
• Tax: R$ 250
• Credit: R$ 125
• Net tax: R$ 125

This scenario shows how non-cumulative taxation works, but it also highlights the need for strict control.

Scenario 3: Sale in installments

A company sells in 10 installments:

• Tax can be withheld at the time of sale
• Receipt occurs over time

This creates a financial mismatch that needs to be planned for.

Tax reconciliation and ERP integration

O split payment IBS CBS requires a profound change in the way companies do tax and financial reconciliation.

Today, many companies calculate taxes on a monthly basis, based on consolidated reports. With split payment, this logic tends to migrate to a model closer to real time.

This requires:

• Integration between ERP and tax systems
• Process automation
• Detailed control of each transaction

Conciliation becomes more complex, as it involves:

• Gross figures
• Net values
• Withholding taxes
• Credits to be offset

Companies without adequate systems can face significant operational difficulties.

This is why investing in technology will be key to ensuring compliance and efficiency.
