R & D Tax Relief



R & D tax relief allows SME companies to either:


  • Deduct an extra 130% of their qualifying R & D costs from their profit, which is in addition to the normal 100% deduction
  • Claim a tax credit if the company is loss making, worth up to 14.50% of the surrenderable loss




Employee costs (including Employers NIC/Pension)

Subcontractor costs






Profit before tax (prior to R & D Claim)                  £200,000

Corporation tax @ 19%                                     £38,000


Following the preparation of a R & D claim, it is calculated that there are R & D costs of £100,000. A further enhancement of 130% is available on these costs so the revised corporation tax due is as follows:


Profit before tax                                             £200,000

Less: R & D enhanced expenditure                         (£130,000)

Revised profit before tax                                    £70,000

Corporation tax @ 19%                                       £13,300


Corporation tax saving £24,700




Loss before tax                                              £200,000

Add R & D enhanced expenditure                           £130,000

Adjusted loss before tax                                    £330,000


The surrenderable loss is the lower of the following:


  • the amount of the unrelieved trading loss sustained in that period (£330,000); and
  • 230% of the related qualifying R&D expenditure (£100,000 x 230% = £230,000)


The lower of these amounts (£230,000) is multiplied by 14.50% to result in a tax refund due of £33,350




You are required to provide HMRC with a copy of your calculations and a report detailing how the R & D project:


  • looked for an advance in science or technology and aimed to achieve this advance
  • had to overcome scientific or technological uncertainty
  • overcame this uncertainty
  • could not easily be worked out by a professional in the field
