SIFIDE – System of Tax Incentives for Business R&D
SIFIDE – System of Tax Incentives for Business R&D aims to increase the competitiveness of companies by supporting their efforts in Research and Development (R&D) through the deduction of R&D expenses from the corporate income tax (IRC).
SIFIDE was created in 1997 as a measure to stimulate the participation of the business sector in the overall R&D effort. The experience resulting from its implementation shows that this mechanism has contributed to an effective increase in R&D activity by Portuguese companies.
SIFIDE II came into effect in 2011 with the introduction of some changes to the legislation that make it even more attractive for companies.
The registration must be made by the person responsible for the company, who may assign the responsibility for preparing and submitting the application to the Application Manager (for example, another employee or an external company).
Once registered, the Application Manager will have access to the company’s data after authorization from the company’s representative.
To use your portal securely, you must authenticate yourself using the Digital Mobile Key (CMD) or the Citizen Card (CC).
