Will your business qualify?

So many businesses engage in innovation every day but don’t realise that it falls under the R&D umbrella. They incorrectly assume these tax credits are the domain of lab coat companies.

That’s not the case, so it’s well worth checking if your organisation’s innovative activities qualify.

Use the calculator below to see how much your innovation is worth.

What is your current financial position?

Annually, how much do you spend on innovation?

Spend includes staff and consumable items (materials, electricity, component parts etc.)


We estimate your claim to be worth:

Sample R&D calculations:

Profit-making SME with £50,000 innovation spend:

£50,000 x 130% Expenditure Enhancement = £65,000

£65,000 (Enhanced Expenditure Value) x 19% Corporation Tax = £12,350

Loss-making SME with £50,000 innovation spend:

£50,000 x 230% Expenditure Enhancement = £115,000

£115,000 (Enhanced Expenditure Value) x 14.5% R&D Surrender Rate = £16,675
