Income and deductions for business

Most income your business receives is assessable income – which means you need to declare it and it's subject to tax.

You can claim tax deductions for most costs you incur in running your business but there are exceptions. For example, you cannot claim deductions for private or domestic expenses. Entertainment, fines and some other expenses are also specifically excluded.

The rules for business income and deductions vary depending on your business structure, whether you hold and sell trading stock, and the nature of your income and expenses.


Record keeping

You must keep accurate and complete records of all your assessable income and deductions you claim. If you make false or misleading statements, we may:

  • determine your income, based on industry benchmarks and other information, and issue an amended assessment
  • apply penalties
  • commence prosecution.
