Tax Deductions for Small Business - Australia

Maximising legitimate tax deductions is one of the most effective ways to reduce your tax bill as a small business. Every dollar you can deduct reduces your taxable income - but you must have proper documentation and the expense must be genuinely incurred in earning your business income. Understanding what you can and cannot claim is the difference between paying the right amount of tax and leaving money on the table.

Step-by-Step Process

  1. 1

    Understand the general deductibility rule: the expense must be incurred in earning assessable income

  2. 2

    Keep receipts and records for every business expense

  3. 3

    Separate personal and business expenses clearly

  4. 4

    Track home office expenses if you work from home

  5. 5

    Record vehicle and travel expenses with a logbook or diary

  6. 6

    Claim depreciation on business assets and equipment

  7. 7

    Review all insurance, professional development and subscription expenses

  8. 8

    Consider timing of deductions - prepaying expenses before year-end
