2026 Program Changes
The Portuguese government's State Budget 2026 indicates intention to phase out the tax benefit for investment in R&D funds (known as 'indirect SIFIDE'). This would affect taxpayers who invest in R&D fund participation units. Direct SIFIDE (for companies conducting their own R&D) remains fully operational. Estimated budgetary impact: €124.2M decrease in 2026, €162.6M in 2027 if indirect SIFIDE is revoked.

Common Questions
Qualifying R&D activities under the SIFIDE - System of Tax Incentives for Business R&D in Portugal generally include systematic investigative work aimed at achieving scientific or technological advancement, developing new products or processes, and resolving technical uncertainties. This encompasses activities such as developing AI algorithms, creating novel software systems, engineering new materials, and conducting experimental development. The work must go beyond routine engineering or application of existing knowledge. Companies should document their R&D projects thoroughly, including technical objectives, methodologies employed, personnel time records, and associated expenditures to substantiate their claims.
Companies typically apply by submitting project details to the relevant government agency or tax authority in Portugal, including descriptions of the R&D activities, technical challenges being addressed, project timelines, and detailed cost breakdowns. Supporting documentation should include employee timesheets, expense receipts, technical reports, and evidence that the work constitutes genuine research rather than routine development. Applications often need to be filed before or during the fiscal year in which expenses are incurred. Engaging a qualified R&D tax advisor familiar with the local regulatory framework is recommended to maximize the claim value and ensure compliance.
