Enter the total of already-eligible spending, net of non-repayable State co-funding, as certified by the declaration from the National Innovation Agency. A year with no R&D spending counts as zero in the average of the two previous financial years.

The Investment Tax Code in force covers tax periods up to 2025. Law 13/2026 of 16 April authorised the Government to extend SIFIDE II to 2026 and to end the indirect route through investment funds, but that authorisation runs for 180 days and the decree-law amending the Code has not been published yet. Until it is, the last period covered remains 2025.

The period's corporate tax charge of €55,000.00 is not enough to absorb the whole credit: €60,000.00 is carried forward. Article 38.º(4) allows it to be deducted up to the 12th following tax period, so it is not lost, only deferred. The deduction stops at the tax charge and never produces a refund.

An educational estimate based on the figures you enter. It does not work out whether the spending is eligible, which is the substance of the regime and depends on the certifying declaration from the National Innovation Agency: the categories in article 37.º, the 120% treatment of level-8 qualified staff and of eco-design projects, and the cap on operating costs at 55% of staff costs. It also leaves out the indirect route through investment funds, the conditions in article 39.º, group taxation, autonomous taxation and the municipal and state surcharges, which sit outside the deduction ceiling. The 1,500,000 EUR limit is applied to the incremental credit itself.
