Patent Box Claims with ForrestBrown

  1. 1

    Establishing eligibility

    The first step is to establish that a business is eligible for Patent Box and that it meets the substance requirements of the regime – the active ownership condition and the development condition.

    Our project team will undertake an initial assessment so we can understand the fundamentals of your patent position. Once we have established eligibility, our specialists will begin to review the more complex details relating to qualifying expenditure.

  2. 2

    Mapping qualifying expenditure

    Next, we stream the business’s income and expenditure to determine how its profits map to its relevant product sales, royalties and license fees, patent sales, infringement income and notional royalties on processes or services.

    Our team of chartered tax advisers and accountants have the technical firepower to determine the extent to which your profits relate to your IP activity, extracting efficiencies and minimising risk.

  3. 3

    Calculating the R&D fraction

    Further adjustments are made to track and trace these profits back to R&D activities attributable to its patents. This is the profit that is eligible for the effective 10% rate of tax.

    Our sector specialists have in-depth industry experience and have unique insight into how R&D activities are undertaken across a range of sectors. Working with our tax team they help to identify relevant IP income to the level of R&D expenditure incurred to develop IP within a claim or project.
