Czech Republic R&D Tax Deduction

The Czech Republic allows companies to deduct eligible R&D costs from their tax base, effectively providing a double deduction since the same costs are also treated as regular deductible business expenses. This R&D allowance applies to personnel costs, materials, depreciation of R&D equipment, and overhead directly related to R&D activities. Unused allowances can be carried forward for up to three years, benefiting companies not yet in a tax-paying position.

Companies must prepare a written R&D project document before starting the project, describing the objectives, methods, expected outcomes, and budget. They must maintain contemporaneous records of R&D activities, time sheets, invoices, and a separate cost accounting for each R&D project. The tax authority may request this documentation during an audit. Having well-organized records from the project start is critical, as retroactive documentation is often challenged.

The enhanced regime increases deductions for collaborative research with Czech universities and Academy of Sciences institutes. Newly eligible costs encompass prototype testing fees from accredited laboratories, specialized research software licensing, and personnel costs for doctoral candidates in structured industrial PhD programs. These expansions incentivize deeper industry-academia collaboration and knowledge transfer acceleration between research institutions and private enterprises.

Companies prepare formal project documentation before commencing qualifying activities, specifying objectives, methodology, outcomes, personnel, and budget allocations. Documentation must be available upon request but requires no advance submission. Claims exceeding CZK 10 million frequently trigger examinations where inspectors assess whether activities constitute systematic investigation resolving technological uncertainty rather than routine engineering adaptation.
