Key Takeaways
- The golden rule: You can claim any expense that is directly linked to producing your **business income.**
- In 2026, the ATO is focusing on "apportionment"—how much of an expense is for business vs. personal use.
- The **Instant Asset Write-Off** is still a powerful tool for businesses under $500 million turnover (conditions apply).
In 2026, many Australian business owners leave thousands of dollars on the table at tax time. Whether it's the cost of your home internet or a piece of equipment you bought in June, every dollar of a legitimate business expense reduces your taxable income. Here is the ultimate 2026 checklist for maximizing your deductions.
The Big Four Categories
Most small business deductions fall into these four broad groups. You must have a **tax invoice** for anything over $82.50 (including GST).
1. Operating Expenses (The Daily Run)
- **Rent & Utilities:** For your office or showroom.
- **Marketing & Advertising:** (Google Ads, physical signage, social media management).
- **Software & Subscriptions:** (Xero, Microsoft 365, industry-specific apps).
- **Insurance:** (Professional Indemnity, Public Liability, Workers Comp).
- **Office Supplies:** (Stationery, coffee/tea for the staff kitchen).
2. Professional Fees & Services
- **Bookkeeping & Accounting:** (Wait, you're paying us? That’s 100% tax deductible!).
- **Legal Fees:** (Related to your business structure or client contracts).
- **Consultancy:** (Business coaching, HR advice).
3. Travel & Vehicle Expenses
- Motor Vehicle:** (Calculated via logbook or cents-per-kilometre).
- **Airfares & Hotels:** (For business trips and seminars).
- **Public Transport & Tolls:** (When visiting clients or sites).
4. Employees & Salaries
- **Gross Wages & Salaries:** (Including bonuses and commissions).
- **Superannuation:** (The 12% SGC—must be paid on time to be deductible!).
- **Training & Education:** (For yourself and your staff in your specific field).
- **Fringe Benefits Tax:** (The tax you pay on staff benefits is also deductible).
💡 Pro Tip: If you use an asset (like your phone or car) for BOTH personal and business use, you must **apportion** the expense. The ATO expects a 4-week diary or 12-week logbook as proof of your percentage.
