R&D Expenditure Credit (RDEC)

Businesses around the UK can reduce their tax bills or claim cash credits as part of their R&D tax credits Capital Expenditure.

Though it was originally known as “Above the Line R&D Tax Relief”, the scheme is now known as RDEC Scheme. Any business carrying out research and development practices is likely to be able to claim R&D tax credits captial Expenditure, though most companies choose to trust established tax advisors, in order to guarantee success. CapEx Tax Specialists can help organisations apply for and claim Research and Development Credits.

This, in turn, will provide greater stability and make it easier for companies to factor in the relief when they make investment decisions. Another positive characteristic of the RDEC scheme is that it can be used by loss-making companies as well.
