SIFIDE II Calculator 2026

SIFIDE II is a Portuguese IRC tax credit for R&D investment: 32.5% of eligible expenses (base rate), plus an incremental rate up to 50% on the increase versus the prior two-year average. Certified by ANI and deductible against IRC.

How to estimate your credit

Enter your eligible R&D expenses for the year and the calculator returns the base estimate (32.5%). The exact figure depends on the incremental component, SME uplifts and expense eligibility — which HVR confirms in the application file.

Legal basis and rates

SIFIDE II is the R&D tax incentive in the Tax Investment Code (Código Fiscal do Investimento, approved by Decree-Law 162/2014). Under Article 38, companies subject to corporate tax (IRC) can deduct from the tax due a base rate of 32.5% of eligible R&D expenses for the year, plus an incremental rate of 50% on the increase over the average of the two previous years, with the incremental part capped at €1,500,000. Base and incremental rates together can reach 82.5% of the extra spend.

What the calculator shows

It applies the 32.5% base rate to the eligible expenses you enter. The incremental part depends on your R&D spending in the two previous years and on which expenses qualify, so it is left to the application file rather than estimated online.

Eligibility and application

The R&D activities and expenses must be certified by the National Innovation Agency (ANI). Applications go to ANI by the end of May of the year after the expenses were incurred. Typical eligible costs include R&D staff, assets used in R&D, R&D contracted from universities and research centres, and patent registration and maintenance.

Worked example

A software company spends €200,000 on eligible R&D in 2026 after averaging €150,000 in 2024 and 2025. The base credit is 32.5% × €200,000 = €65,000 and the incremental credit is 50% × €50,000 = €25,000, for €90,000 deductible from IRC, subject to ANI certification. The credit is claimed in the Modelo 22 corporate tax return for the year. HVR assesses eligibility and prepares the application file as part of its business consulting.
