Deductibility
Whether an expense may be subtracted from income in computing taxable profit.
Also called

Where you meet this
Deductibility is the question of whether an expense can be subtracted from income before tax is computed. It is the single commercial reason invoicing discipline pays for itself: unsupported expenditure is taxed as though it were profit. The exposure usually sits on the buying side rather than the selling side, which is where businesses tend not to look.
What it sits alongside
In Kenyan business records deductibility sits alongside Tax invoice, Purchase invoice and Income tax. The pages for each explain how they connect.
