# Brazil e‑invoice, split‑payment and tax reform rollout > Live situation record from CLSTR: https://clstr.news/situations/brazil-electronic-water-billing-rollout > Updated: 2026-07-28T15:27:56.000Z. Sources: 47. Developments: 5. By late July 2026 Brazil’s electronic water‑billing rollout continued to expand, with utilities adding QR codes for Pix payments and links to full tax invoices. The federal mandate to use the National NFS‑e portal for all service invoices took effect on 1 August 2026, obliging municipalities such as Nova Iguaçu to issue invoices exclusively through the portal while still accepting earlier documents. From 3 August 2026 companies in the regular tax regime were required to add IBS (Imposto sobre Bens e Serviços) and CBS (Contribuição sobre Bens e Serviços) fields to every electronic fiscal document; documents missing these fields are rejected. A symbolic collection of the new taxes began in August 2026 with a uniform 1 % test rate (0.1 % IBS, 0.9 % CBS). Full collection for B2B transactions under the split‑payment system starts on 1 January 2027, with the mechanism retaining tax amounts at the point of sale via Pix, card or bank transfer and slated to extend to retail and replace ICMS and ISS entirely by 1 January 2033. The NFS‑e portal’s XML schema was updated to include the new fields, alphanumeric CNPJ support and IBS/CBS groups, moving from a restricted‑production environment on 27 July 2026 to full production on 10 August 2026. NF‑e and NFC‑e must display the new fields from 3 August 2026; NFS‑e adoption begins 1 October 2026 for most services and 1 December 2026 for digital platforms, rentals and condominiums, with Simples Nacional firms facing a unified deadline of 1 January 2027. A Serasa Experian survey found 42 % of SMEs unable to assess the reform’s impact and 40 % uncertain of their preparation stage, prompting industry calls for early system upgrades. ## Claims - From 1 August 2026, Nova Iguaçu taxpayers must issue electronic service invoices exclusively through the National NFS‑e portal.
