💼 Accountant Tax Deductions Australia
CPAs, BAS Agents & Financial Advisors — your complete 2026 ATO guide.
Last updated: May 2026
If you work as an accountant in Australia, you're entitled to claim a deduction for many of the costs you incur doing your job. The ATO has specific rules about what counts and what doesn't — and getting it right can mean a meaningfully bigger refund. This guide covers every tax deduction available to Australian accountants for the 2025–26 financial year, based on published ATO guidance for the Finance & Business sector. We break down what's fully deductible, what's partially deductible (and how to apportion it), and what to avoid claiming.
The 3 ATO golden rules
To claim a work-related deduction, you must meet all three:
- You paid for it personally and weren't reimbursed.
- The expense directly relates to earning your income.
- You have a record (usually a receipt).
✅ Fully deductible 14 items

Car expenses (between offices, clients)
Travel between offices or to clients is deductible; commute is not.
Home office running costs
Electricity, gas, and depreciation of office furniture used for work are deductible (70c/hr fixed rate or actual cost method).
❌ Not deductible 1 items
Common audit traps. Claiming these can trigger ATO review and penalties.

What's the simplest way to track accountant deductions during the year?
Keep a separate folder or app (like Receipt Bank or your phone's notes) and capture every work-related receipt as you spend. The 'shoebox approach' costs most accountants thousands in lost refunds each year.
Can I claim something my employer reimbursed?
No. If you've been reimbursed (or it was salary-packaged), you can't claim a deduction for it as well.
Do I need receipts for everything?
You need a receipt or written record for any deduction. For laundry up to $150 and small expenses up to $300 in total, you can use the ATO simplified methods without keeping every receipt.
What's the difference between deductible and partial?
Fully deductible means you can claim 100% of the cost. Partial means it's split between work and private use — you can only claim the work-use percentage based on a diary or logbook.
How long do I need to keep my receipts?
Five years from the date you lodge your tax return. The ATO can ask for records anytime in that window.
