Enter the supported company and shareholder scenario to see Corporation Tax, Marginal Relief, dividend tax, and owner net proceeds.

Estimate the small-profits rate, main rate, or Marginal Relief for the supported accounting period.
Model a percentage of separately confirmed distributable reserves and the owner’s shareholding.
Estimate incremental personal dividend tax and net proceeds without treating company profit as automatically distributable.
The calculation uses uk-company-tax-2026-v1 and the same effective-dated dividend engine as the focused dividend tool. A qualified accountant or tax adviser should confirm the tax base, associated-company position, reserves, and final liability.
We can connect validated calculations to approvals, systems, audit evidence, and exception handling.
