Split payment in Brazil: how it changes the way you collect invoices

A Brazilian company that sells to other businesses is used to collecting the full invoice, tax included, and paying that tax a few weeks later. During that gap, the tax money works as free working capital. Split payment is designed to close the gap: the tax is separated when the payment is made, and the supplier's account receives less than the invoice says.

At Soulbit Academy, we look at split payment from the treasury side rather than the tax side. The companion article on IBS and CBS, published the same day, explains what each tax covers and how the reform is built. Here we take that foundation as known and deal with cash flow: how much comes in, when it comes in, how much working capital is lost and what is worth preparing.

What split payment is and what changes when you collect an invoice

Split payment is the mechanism through which Complementary Law 214/2025 provides for the consumption tax to be separated at the financial settlement of each payment, so that the seller receives the net amount and the tax authority receives its share directly. The law regulates it in articles 31 to 35 and ties it to the two taxes of the reform: the federal CBS and the IBS levied by states and municipalities.

One paragraph of context is enough. The CBS replaces PIS and COFINS, and the IBS replaces ICMS and ISS, with a phased transition from 2026 to 2033. The year 2026 is a test year: the CBS is reported at 0.9% and the IBS at 0.1%, both offsettable against PIS and COFINS, with no effective collection and with ancillary obligations on the electronic invoice. The Federal Revenue Service places the start of real CBS collection in 2027, together with the end of PIS and COFINS, in its official guide to the consumption tax reform.

Today the flow is linear: the company issues the invoice, collects the full amount and calculates its taxes at period close. With split payment, the payment system identifies the transaction, checks how much tax is due and diverts it before crediting the remainder to the supplier. The company is still the taxpayer, but the timing of the tax payment is no longer its decision.

Is split payment a new tax?

No. Split payment creates no tax obligation: it changes the form and timing of collection. The CBS and the IBS are the taxes; the split is the pipe through which part of them reaches the tax authority. That is why its main effect is measured in liquidity, not in the total tax burden.

When split payment arrives: what the law says and what is still unconfirmed

The law does not set a single start date for split payment: it tasks the Federal Revenue Service and the IBS Management Committee with defining a gradual rollout. As of October 2026, we could not verify a published official calendar, and the sources we consulted disagree with one another. This article therefore does not state a date.

What specialist press reports as of October 2026 is the following. The first point is an optional start in 2027, limited to business-to-business transactions, with no consumer sales, cards or individual microentrepreneurs. The second is that it becomes mandatory for business-to-business transactions from 2028, with financial institutions joining gradually. The third is that the calendar has moved more than once in 2026, and the decision on which payment methods go first remains open. These are press reports, not an official act, and should be treated as provisional.

The law also distinguishes procedures. Under the general procedure, the payment system consults the Management Committee and the Federal Revenue Service to determine how much tax is separated. Under a simplified procedure, the separation uses simpler parameters and, according to several commentators' reading of the legal text, a buyer in the regular regime does not obtain credit for what was separated that way. Confirm that point in the text of Complementary Law 214/2025 on the Planalto website or with your tax adviser before basing a decision on it.

Split payment and cash flow: the supplier collects the net amount

The central effect of split payment on cash flow is that the cash arriving on the collection day is smaller than the invoice amount, because the tax is set aside before it reaches the supplier's account. The tax does not disappear: it is paid at the moment of collection rather than at period close.

Take an illustrative case. A company invoices BRL 200,000 to another business and assumes that BRL 30,000 of that invoice is consumption tax. Under the current setup, it collects BRL 200,000 and pays the BRL 30,000 to the tax authority, say, 45 days later. With split payment, it collects BRL 170,000 and the BRL 30,000 is separated at settlement.

Collection item	Without split payment	With split payment
Invoice amount	BRL 200,000	BRL 200,000
Tax included in the invoice (assumed)	BRL 30,000	BRL 30,000
Cash arriving on collection day	BRL 200,000	BRL 170,000
Tax the supplier pays later	BRL 30,000, about 45 days later	BRL 0, already separated
Working capital financed by the tax	BRL 30,000 for about 45 days	BRL 0
Cost of financing that tax (assumed 1.0% per month)	BRL 450	BRL 0

The aggregate effect depends on volume. A company that collects ten invoices like this one each month stops having BRL 300,000 of implicit financing, and that amount has to come from somewhere else: own cash, a credit line or receivables discounting. The company does not lose a tax, it loses an involuntary supplier credit that the tax authority used to grant it.

Who feels this calendar change the most?

Companies with thin margins and a high share of tax in the price. When tax weighs heavily on each invoice, the cash gap is larger, and if the collection cycle is long, treasury funds those days with its own resources. The rest of the cycle, supplier payment terms and inventory, determines how much of the gap is absorbed.

Working capital and tax credits: the other side of net collection

Split payment moves money out of the supplier's working capital and into the tax authority, but it does not remove the buyer's right to credit when the buyer is in the regular regime. The IBS and CBS system works on credit for what was paid along the chain. The split ensures the tax reached the authority at each link, and that is what supports the credit.

This creates an asymmetry in each company's flow, and treasury has to look at both sides. As a seller, it collects net and the tax stops being financed. As a buyer, the payment to the supplier is also divided: the supplier receives the net amount, but the company still pays the full invoice, and the credit is recognised under the rules of the system. Confirm that part with your accountant, because the credit treatment may vary with the procedure used.

The consequence for working capital comes down to three fronts. The first is the cash conversion cycle: the period in which the tax financed the business shortens, and the effective cycle lengthens in net terms. The second is the credit line: if the company financed part of the cycle with bank credit, the new calendar may raise the average drawn balance. The third is receivables discounting: the discountable amount changes if the invoice is collected net. To measure the first front, the guide on the cash conversion cycle and the cost of idle cash provides the method.

Reconciliation and forecasting under split payment: from invoice to settled net

Bank reconciliation gets harder because the amount that arrives no longer matches the invoice. Today treasury reconciles BRL 200,000 against a BRL 200,000 invoice. With split payment it reconciles BRL 170,000 against a BRL 200,000 invoice and a BRL 30,000 separation that must be documented. If the accounting system does not record that difference as tax collected at source, open items and false variances will appear.

There are four minimum changes to the process. The first is to add two fields to each receivable, the expected net amount and the expected separated tax. The second is to review automatic reconciliation rules, which usually compare amount to amount. The third is to agree with the tax team how the separated tax is recorded, so that the credit and the obligation are properly reflected. The fourth is to document the exception, meaning what happens when a payment does not go through a method subject to the split and arrives gross. Anyone who already manages accounts in several currencies will find the guide to multi-currency bank reconciliation useful.

The cash forecast needs the same treatment. The sales revenue line splits into net collection and separated tax, and the tax payment line disappears for the part already collected at settlement. If the flow includes revenue in reais and costs in another currency, each line still needs its own exchange-rate assumption, as explained in the guide to a cash flow forecast with foreign currency revenue. For those who convert reais, the cost of conversion also matters, and the article on IOF tax on foreign exchange for companies in Brazil describes that other layer.

Contracts, pricing and what treasury should prepare for split payment

Preparing treasury for split payment means reviewing six points that do not depend on the exact start date. That is the reason to do it now: the work is the same under either of the two possible calendars.

The first is the collection map: which customers pay through which method, because the split will be applied gradually by payment method. The second is the cash model: two columns per collection, net and tax, and one scenario with the split and one without. The third is contracts: price and payment clauses should state clearly that the amount payable is the gross invoice and that receiving a net amount because the tax was separated is not a partial payment. Without that clause, a customer may read the difference as an outstanding balance.

The fourth is pricing. If the cash gap has a cost, that cost should appear in commercial policy: payment terms, early-payment discounts and conditions for customers who pay through methods outside the split. The fifth is funding: work out how much additional credit line the new calendar requires and negotiate it before you need it. The sixth is accounting: how the credit and the liability for the separated tax are recorded, a decision best settled with your tax adviser. Next year's budget decisions benefit from the guide to the 2027 budget and the exchange-rate assumption.

What Soulbit V1 delivers and what it does not on split payment

Soulbit V1 has no connection to the split payment mechanism: it does not apply it, does not separate or withhold taxes and does not integrate with the Federal Revenue Service or the IBS Management Committee. Soulbit is not a bank or a tax adviser, and the tax treatment of each receipt is the responsibility of the company and its accountant.

What V1 does offer is a business account with balances in stablecoins (USDC and USDT) and in fiat (USD, EUR and GBP), institutional custody, conversion through OTC quotes on request, payment links and collection QR codes. It is a layer that helps a company with international operations keep part of its liquidity in digital dollars and decide when to convert. V1's local bank rail exists only in Colombia: there are no confirmed Brazilian rails, and this article does not present them as a Soulbit capability.
