Research & Development Capital Allowances (RDA)

You may know them by their full name - Research & Development Capital Allowances - or just by the acronym RDAs.

What is it?

How does an RDA accelerate the timing of an improved post-tax position?


An RDA is the Capex equivalent of the R&D tax relief scheme that allows R&D that is capital in nature for tax purposes, 100% of the capital cost to be depreciated in the year the cost was incurred (rather than applying the appropriate depreciation policy). As a result, RDAs can make a significant positive impact in reducing your tax liabilities in this first year. Unlike AIA's, there's no limit on the amount that can be claimed.

The MMP Tax team will help to make sure you're not missing out

If any of the following apply to your company, then you should strongly consider applying for an RDA:

  • You have constructed or purchased a laboratory, lab equipment, a test bed, or pilot plant
  • You have purchased tangible assets, plant and equipment, specifically for R&D purposes
  • You have understood that your capital expenditure is ineligible for R&D tax relief

    We keep track of HMRC's assessment criteria, and tailor every new RDA application to the latest guidance. The Government's official manual on RDA claims is split into 9 sections, which can look especially daunting.
