Business Expenses

Business expenses are expenses you have paid to run the business. Some examples are CPF contributions, wages, renovation, advertising, etc.

Business expenses may be deductible or non-deductible. When deductible, they reduce your taxable income and the amount of tax you need to pay.


Income  $80,000
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)


Deductible Business 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:

Expenses are solely incurred in the production of income.

Expenses are not a contingent liability, i.e. it does not depend on an event that may or may not occur in the future. In other words, the legal liability to pay the expenses must have arisen, regardless of the date of actual payment of the money. 

Expenses are revenue, and not capital, in nature.

Expenses are not prohibited from deduction under the Income Tax Act.

Non-Deductible Business Expenses

Non-deductible business expenses are activities you or your employees pay for that do not fulfil the conditions above. This includes 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 purchase of fixed assets.
