Municipal active debt and Complementary Law 208/2024

The assignment reaches the proceeds of the claim — the financial flow — not ownership of the tax claim itself.

The public entity retains authority over collection, registration and tax enforcement. The assignee does not become a tax creditor and acquires no treasury prerogatives.

The nature of a tax claim is inalienable: the law did not turn taxes into private assets, it merely permitted onerous assignment of collection proceeds.

A municipality's active-debt stock typically accumulates decades of registrations, including time-barred claims, non-existent debtors, unrecoverable amounts and duplicates.

Diligence begins by stratifying the stock: age of registration, type of tax, debtor registry status, existence of security and collection history by band.

Registered nominal value and the present value of recoverable flow typically differ by orders of magnitude.

The municipality's fiscal capacity and governance — the drivers of flow predictability.

The quality of the municipal attorney's registry and database.

Specific legislative authorisation, following the proper procedure and compliant with the law.

Vehicle structure and investor protections, including asset substitution mechanisms.

This is a new asset class in Brazil. The regulatory framework continues to consolidate and case law on specific points is still forming.

The practical consequence is that required diligence is proportionally greater than in mature classes, and structures tend to incorporate more conservative protections.
