Is corporation tax paid at the end for the whole accounting period or per sale?

Question

for example if i sell three products naming them ONE, TWO and THREE for simplicity and I make £10 profit each on ONE (sold in Jan) and TWO (sold in Feb) but THREE does not make any profit or maybe has to be sold at a loss so -£5. will i pay corporation tax on per sale basis now or on the £10 £10 (-£5)=£15 for the whole yearly period. I hope i have explained well in my waffle and baffle:)

Answer 1

In the UK, Corporation Tax is calculated and assessed on the taxable profits for the whole accounting period, normally one year. You couldn't calculate this for each sale anyway, because most of the allowable costs relate to the whole business and not one individual transaction. Rent, Rates, wage costs etc.

Answer 2

In the US, its monthly for a corporation.  And you can subtract any money you lost.  Because it is net profits, and not not sales.
