Corporation tax: the 26.5% band between £50,000 and £250,000

Companies with profits between the two limits pay an effective marginal rate of 26.5%, higher than the main rate. Knowing where your profit falls changes how you plan.

Insight2 min readShare

Corporation tax has two headline rates: 19% on profits up to £50,000 and 25% on profits above £250,000. In between, marginal relief eases a company from one to the other. The average rate rises smoothly, but each extra pound of profit in the band is taxed at 26.5%.

Why it matters

A company with £150,000 of profit pays £36,000 in corporation tax, an average of 24%. If it makes £10,000 of deductible spending before its year end, such as an employer pension contribution or a planned equipment purchase, it saves £2,650 in tax: more than it would at either the 19% or the 25% rate.

The limits are shared between associated companies and reduced for short accounting periods. A company with three associated companies divides them by four, so its band runs from £12,500 to £62,500.

Questions worth asking before the year end

  • Where will this year’s profit land, and how much of it falls in the 26.5% band?
  • Is planned spending that qualifies for capital allowances better made before the year end?
  • Are director pension contributions part of the plan?
  • Do associated companies reduce your limits?
