Franked Investment Income
UK Corporation Tax.
Franked Investment Income is often part of the income of a UK tax paying company.
It means dividends received from other UK companies (which are not in the same UK tax group).
Dividends are paid net, but they have an associated tax credit, reflecting the corporation tax already paid by the dividend-paying company.
For tax calculation purposes, the amounts of the related tax credits are added to the net amounts of the dividends actually received.
The Franked Investment Income is the grossed up amount of the net dividend plus the tax credit.
