Corporation tax for the current accounting period: imported months as they are, the rest forecast by you.
Type over any forecast figure. Depreciation and disallowable in forecast months come from the starting point you fill from, so the tax add-backs carry on; they don’t change when you type over overheads.
Accounting profit (income less cost of sales and overheads, leaving out lines you marked Leave out), plus depreciation and disallowable costs, less capital allowances, plus any other adjustment you enter.
Worked out with the rules on the Settings page: small profits rate, main rate, and marginal relief in between, with the limits divided by associated companies plus one. A period that straddles two financial years is split by days.
The tax divided by the whole months left until it’s due, at least 1. It doesn’t know what you have already put aside.
Losses brought forward, group relief, dividends received from other companies, research and development relief, and paying in instalments as a large company.
