Business expenses are expenses you have paid to run the business. Not all business expenses are deductible.

What is Deductible

Deductible business expenses reduce your company’s taxable income and the amount of tax you need to pay.     


Business Expenses 15,000
 - Deductible Business Expenses 5,000
 - Non-Deductible Business Expenses 10,000
Income Subject to Tax ('Taxable Income')80,000 - 5,000 = 75,000
(Income minus deductible expenses)

Generally, deductible business expenses are those 'wholly and exclusively incurred in the production of income'. In other words, they must satisfy all these conditions:

  • The expenses are solely incurred in the production of income.
  • The expenses are not a contingent liability i.e. they do not depend on an event that may or may not occur in the future. In other words, the expenses must be incurred. An expense is 'incurred' when the legal liability to pay the expense arises, regardless of the date of actual payment of the money. 
  • The expenses are revenue, and not capital, in nature.
  • The expenses are not prohibited from deduction under the Income Tax Act 1947.

What is Non-Deductible

Non-deductible business expenses are activities you or your employees pay for that do not fulfil the conditions above. These include personal expenses (such as travel, or entertainment not related to the running of the business) and capital expenses (such as expenses incurred to incorporate a company and the purchase of fixed assets).

Learn how to make tax adjustments (such as adding back non-deductible business expenses) to arrive at the income that is chargeable to tax.
