2026: What Changes in Taxes in the Reform's First Year

Executive Summary

2026 is the first year in which your company needs to move beyond curiosity and into real preparation for the new system. Even though the transition is gradual, this is the moment to review processes, contracts, and technology so you are not caught off guard later on.

What Really Changes in 2026

The main shift in 2026 is not the total replacement of the old taxes. It is the new system entering your company’s planning routine.

In practice, 2026 requires:

  • assessing the operations affected;
  • reviewing your ERP and tax invoicing;
  • training the finance, tax, and accounting teams;
  • organizing the data needed for credits and reconciliation.

Where Business Owners Go Wrong

The most common mistakes in this first year are:

  1. assuming the reform only matters once the final rate appears;
  2. waiting for the supplier or the accountant to solve everything alone;
  3. keeping contracts without a tax-revision clause;
  4. ignoring the transition’s effect on cash flow.

What to Do Still in 2026

  1. Map sensitive operations: sales, purchases, services, and recurring contracts.
  2. Review systems and records: without clean data, there is no reliable calculation.
  3. Train the team: a reform without training turns into rework.
  4. Build a cash-flow scenario: the change in the timing of collection — especially with Split Payment — may weigh more than the rate itself.
  5. Follow the regulation with discernment: not every news item becomes a rule that applies to your case.

Conclusion

2026 is not the year when everything changes at once. It is the year your company decides whether it will enter the transition prepared or behind.
