This update prepares Odoo for Brazil's upcoming shift to a new consumption tax system starting in 2026.

The changes adapt existing modules to comply with Avalara's requirements.

2026 marks the start of Brazil's 8-year plan to migrate to a completely new consumption tax system [1]. The new system is meant to be simpler than the old one, but we defer to Avalara for tax calculation so we don't really notice it technically.

The old and new system have to coexist for the foreseeable future because the rollout happens gradually over many years. Whether the new system has to be enabled depends on the federal state the business is in, the type of transactions they do, and other factors. The user has the option to enable it through the l10n_br_is_icbs Boolean flag on the company, which gates all the new functionality.

These changes impact both tax calculation and EDI. This set of modules adapts our existing l10n_br* modules to the new requirements set out by Avalara. We are required to send extra values to their API, and in some cases adapt existing ones.
