RDEC R&D Tax credit helps innovative businesses undertaking R&D related activity claim a generous corporation tax deduction. It is aimed at large companies, but SMEs may be able to claim in certain circumstances.


R&D tax relief is a tax incentive from the UK Government designed to encourage companies to invest in R&D.
The scheme has been around since 2000 and last year over 9,000 UK companies claimed £3.4bn in RDEC tax relief. See here for more R&D tax credit statistics.
Since 2011, Jeffreys Henry’s specialist R&D tax team have provided an end-to-end service to existing clients, new businesses and our network of professional introducers.

Research and Development Expenditure Credit (RDEC) is typically claimed by large companies. Other factors such as having received grant funding and carrying out R&D work for a large company can restrict access to the SME scheme.

RDEC is available if you are a large company for R&D purposes with:

  • more than 500 staff
  • a turnover of more than €100m or a balance sheet total more than €86m


The main difference between R&D for SMEs and the Large company scheme (RDEC) is the costs which qualify under the RDEC scheme. Subcontracted expenditure cannot be claimed unless it has been directly undertaken by a scientific research organisation i.e. a charity, university, or an individual.

SMEs with a turnover less than €100m, may be eligible to claim SME Research and Development Expenditure Credit.


For large companies and SME’s who fall under the RDEC scheme you will be able to claim a tax credit for 12% of your qualifying R&D expenditure from 1st January 2018 and 13% from 1st April 2020.


An RDEC claim is a taxable ‘above-the-line’ credit of 13% of the qualifying expenditure identified. This is subject to corporation tax at 19%, and is calculated as a deduction from your tax bill. If there is no tax payable, the net amount can be claimed as a cash credit.

A company has identified £100,000 of qualifying expenditure incurred on its R&D project.

The net RDEC amount claimable as a credit is calculated as follows.

Above the line credit: £100,000 x 13% = £13,000

Net RDEC amount claimable: £13,000 – (£13,000 x 19%) = £10,530

After tax benefit: £10,530 / £100,000 = 10.53%

HMRC tackle SME R&D Tax Relief abuse

HMRC has released its review of R&D tax relief (also known as R&D tax credit), alongside details that confirm extra measures that will be put in place to end the abuse of R&D tax relief. Recent data suggests a loss of over £300 million due to fraud and error in R&D claims. In such cases, companies had claimed cash through the payable tax credit, despite having no R&D activity. Moreover, HMRC have also identified structures that had been set up with the intention to claim the payable tax credit, despite there being little employment or activity in the UK.

SME R&D Tax Relief – Impact of CBILS, Bounce Back Loans and State Aid

The government has classed the CBILS and the Bounce Back Loan as ‘Notified State Aid’ (NSA) under the European Commission’s new Temporary Framework for COVID-19. If a company receives CBILS or the Bounce Back Loan, then it will not be possible to claim SME R&D Tax Relief for that project as a company can only be in receipt of one form of NSA on any one project.
