Calculate UK corporation tax including small profits rate, marginal relief and main rate. Adjust for associated companies.
The £50,000 and £250,000 thresholds are divided by the number of associated companies. If you have 2 associated companies, the small profits rate applies on profits up to £25,000.
Marginal relief, associated companies, R&D claims, group structures, capital allowances — the calculator covers the basics, but most CT savings come from planning before transactions, not after. Book a review.
