Research and Development (R&D)
Companies can claim enhanced deductions for expenditure on R&D projects at rates broadly dependent on the size of the company as follows:
Small and medium(SME): 225% of qualifying expenditure
Large: 130% of qualifying expenditure
Where the SME deduction for R&D is claimed and the company makes a loss, it can claim a cash credit from HMRC of 11% of that loss. This rate is increased to 14.5% where the R&D expenditure is incurred from 1 April 2014.
Around 46 enterprise zones have been formed around the country to encourage investment and job formation. Businesses in some of those zones can claim 100% capital allowances on the equipment they use within the zone. The period for which those 100% allowance are available has been extended by three years to 31 March 2020.
