R&D Tax Credit Calculator

The calculator below will provide you with an estimate of the corporation tax savings that you could receive from HMRC, as well as the cost for using Tax Cloud.

Required Information

Which scheme are you eligible for? A SME scheme means your company has: - less than 500 employees - an annual turnover of less than €100 million OR a balance sheet of less than €86 million.

A Large Scheme, also known as the ‘RDEC’ scheme, means your company: - has more than 500 employees - Annual turnover exceeding €100 million - a balance sheet exceeding €86 million.

Please note that if a company has received a project grant, it can only apply for this under the Large Company Scheme (RDEC). Additionally, SMEs that have been contracted to do R&D by a Large Company may claim for this work under the RDEC scheme. SMEs that have been contracted by another SME cannot claim for this work.

Enter the amount you spent in your last accounting period on sub-contractors, freelancers, and agency workers working on R&D projects. Unconnected subcontractors and agency workers must be claimed at 65% of the value of the expenditure. The calculator will work this out for you. Connected subcontractors or agency workers (such as within the same group) can be included with the expenditure on staff, software and consumable items, as they can be claimed at 100% of their value.
