Split payment: float goes to zero

There is a credit line on almost every Brazilian company's balance sheet that was never contracted, never priced and never disclosed in a note: the interval between the moment tax accrues and the moment it is remitted. The sale happens today; assessment closes at month end; payment goes out later. In that gap, the State's money works inside the company's account. Nobody agreed to this — it is simply how the tax calendar was drawn. And, like every involuntary financing, it only becomes visible on the day it ends.

Split payment inverts the mechanics: tax is separated at the moment of financial settlement, not in the following month's assessment. The money divides at source — part to the supplier, part to the State — and the gap disappears. For those selling cash with a long remittance deadline, a source of working capital that had been there for decades vanishes. For those selling on credit, the arithmetic changes differently, because receipt and accrual stop moving to different beats. In both cases the effect is not on the result: it is on treasury, which is where companies break.

There is a second effect, quieter and more expensive. While assessment was monthly, a classification error had thirty days to be found and fixed before it turned into money. With separation at the point of sale, the error becomes lost cash immediately, and the correction becomes a refund claim — with all the procedure, the deadline and the paperwork that entails. The tax registry, which used to be accounting's problem, becomes treasury's problem. Few companies have noticed that those two areas have just become the same area.

The test is a three-line calculation you can run with the bank statement in hand. Take the last twelve months of tax remitted, work out the average interval between the taxable event and actual payment, and multiply the average balance by that interval at the rate your bank charges you today. The figure that comes out is the annual cost of the financing you will need to contract to replace what used to be free. It is an uncomfortable figure — and better discovered now, over a coffee, than in February, on the phone with your relationship manager.
