A tax regime chosen for an earlier stage of the business may no longer reflect current revenue, payroll, activities or margins. Changes in the operation are a reason to revisit the assumptions.

Look beyond the tax payment

Growth, a change in payroll, a new activity or a reduced margin can make an old comparison unreliable. Knowing the current Simples annex and how revenue is classified is part of understanding the position.

Compare the whole operation

A reliable comparison uses historical revenue and a consistent projection, together with payroll, owners’ remuneration, costs and the owners’ personal-tax position. Compliance work and the documents required for each regime are part of the cost.

  • Reconcile revenue by activity and period.
  • Review payroll and Fator R where applicable.
  • Compare contribution margins and relevant costs.
  • Include declarations, accounting records and owner withdrawals.

Respect the decision calendar

Election and transition deadlines depend on the year and circumstances, including specific calendars during tax reform. Review the official rules before deciding; do not assume a change can always be made immediately.
