Currently Research and Development costs can be claimed back at 200%. Here is a statement from HMRC’s website:
“From 1 April 2011, the tax relief on allowable R&D costs is 200 per cent – that is, for each £100 of qualifying costs, your company or organisation could have the income on which Corporation Tax is paid reduced by an additional £100 on top of the £100 spent. It also includes a payable credit in some circumstances.”
