Micro and small companies opting for Simples Nacional that provide services will have to issue their invoices only through the national system, Emissor Nacional, according to Revista Oeste. The rule also applies to providers that currently use city hall systems, including in municipalities that already have their own transmitter.
According to the publication, the obligation would begin on September 1st, but was postponed until November 1st. The basis of the measure is CGSN Resolution No. 191/2026. Issuance can be done via the web platform or via API, which offers companies two ways of operating the new system.
There is still a deadline on the companies' calendar. According to Revista Oeste, the period to settle pending issues and complete registration for Simples Nacional ends on Friday, October 30th. Pending issues can be checked on the Simples Nacional Portal. Entry takes place in 2027, and the calendar is now brought forward by resolution, as it was previously defined at the beginning of the year.
The report associates the topic with the Tax Reform, which changes the Simples Nacional options with regard to IBS and CBS. The details of these changes were not provided in the excerpt that served as the basis for this article, so their scope is still unclear.
In practice, what is at stake is the adaptation of billing processes to a single system and the predictability of a calendar that has already been postponed. For those who advocate less bureaucracy and clear rules for entrepreneurs, centralizing issuance can simplify the obligation, as long as the transition occurs smoothly.
What changes for the investor
For those who invest on the stock market, the direct effect tends to be small, as those opting for Simples Nacional are, in general, small companies that do not have shares traded on the stock exchange. The possible impact is on administrative costs and the effort to adapt service providers, which may be of interest to those who follow service sectors. It is worth observing how the Tax Reform will detail the regime options and whether the current schedule will be maintained.
