Without getting too specific . . . a lot! Companies can deduct up to 175% of qualifying expenditure when calculating their profit for tax purposes. What's more, you can claim R&D tax relief on expenditure that's up to three years old.

The precise size of the tax credit will depend on the size of your company, its tax rate and how many of your activities are eligible. Smaller companies, for example, can claim at a higher rate and qualify for extra financial support if they're loss making.
