giveing money to charity?

Question

@ what ratio is it tax deductible in the UK?

Answer 1

If an individual donates money under gift aid then this is deemed to be net of basic rate tax (22%). The charity then reclaims that tax.

If you are a standard rate taxpayer thete is no further deduction but if you pay at the higher rate you can claim the additional relief (i.e. 40 - 22 = 18% of the gross figure)

A business making allowable deductions would just deduct the donation from its profits just like any other expense.
