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.
Understand the general deductibility rule: the expense must be incurred in earning assessable income
Keep receipts and records for every business expense
Separate personal and business expenses clearly
Track home office expenses if you work from home
Record vehicle and travel expenses with a logbook or diary
