Small Business Tax Deductions Australia (ABN Guide)
If you run a small business with an ABN in Australia, you can claim tax deductions for most expenses directly related to earning your income. This includes tools, vehicles, software, home office costs, and ongoing business expenses — but only the business-use portion.
If the expense helps you earn income, it’s deductible. If it’s personal, it’s not. That sounds simple, but most business expenses aren’t black and white — they sit somewhere in the middle. That’s where people either lose money or create problems.
What Small Business Owners Can Claim
| Expense Type | Tax Deductible? | Notes |
|---|---|---|
| Tools & Equipment | Yes | Immediate or depreciated |
| Vehicle Expenses | Yes (partial) | Work-related use only |
| Software & Subscriptions | Yes | Fully deductible |
| Home Office | Yes | Based on usage |
| Phone & Internet | Yes (partial) | Apportioned |
| Insurance | Yes | Some partial |
| Training | Yes | Must relate to current income |
This table looks straightforward — and it is. The issue isn’t understanding categories. The issue is execution. Most ABN holders either don’t track these properly during the year or don’t understand how to apply them correctly at tax time.

The Biggest Mistake: Missing Small Deductions
Most small business owners focus on the big-ticket items. Equipment. Vehicles. Large purchases.
That’s not where the real loss happens.
It’s the smaller expenses — the recurring costs that quietly stack up:
- subscriptions
- minor tools
- partial usage costs
Over 12 months, these often exceed the big purchases. If you’re not tracking them consistently, you’re not claiming them. And if you’re not claiming them, you’re overpaying tax.
Tools and Equipment
If you use tools to earn income, they are generally tax deductible. That part is simple. Where it gets messy is how they are claimed.
Lower-cost tools can usually be claimed immediately. Larger purchases must be spread over time through depreciation. This is where mistakes happen — claiming too much too quickly or not claiming at all.
The correct treatment matters. It affects both your refund and your compliance position.
Vehicle Expenses
If your vehicle is used for business, you can claim a portion of the associated costs. That includes fuel, servicing, insurance, and registration.
But the key word is “portion.”
You must separate business use from personal use. And this is where most ABN holders get it wrong. Either they claim too much, or they avoid claiming altogether because they’re unsure.
One rule catches people every year:
Driving from home to your regular place of work is not deductible.
That single misunderstanding drives a large percentage of incorrect claims.
Software and Subscriptions
This is one of the cleanest deductions available — and one of the most overlooked.
If you’re paying for tools to run your business, they are generally deductible. Accounting software, design tools, booking systems, industry platforms — if they help you earn income, they count.
The problem is they don’t feel like “big expenses,” so they get ignored. But across a year, they can add up significantly.
Home Office Costs
If you operate your business from home, you can claim a portion of your household running costs.
This includes electricity, internet, and phone usage. While each component may seem minor, the total impact over a full year is meaningful.
Most people either:
- don’t claim anything
- or claim incorrectly
Both outcomes cost you.
Phone and Internet
These are almost always partially deductible — but rarely fully deductible.
You need to apportion usage between personal and business. That means understanding how much of your usage actually relates to income-producing activity.
Guessing is not a strategy.
Tracking once properly removes the problem permanently.
Insurance
If you’re protecting your business or your income, the cost is generally deductible.
This includes:
- public liability insurance
- professional indemnity
- income protection (partially deductible)
These aren’t optional extras. They’re part of running a business — and they should be treated that way in your tax return.
Training and Education
Education expenses are deductible if they improve your current income.
That’s the key distinction.
If the training helps you perform your current work better, it’s deductible. If it’s preparing you for a different career, it’s not.
This line is often misunderstood — and misapplied.
Immediate Deduction vs Depreciation
| Type | Treatment |
|---|---|
| Low-cost items | Immediate deduction |
| High-cost assets | Claimed over time |
This is one of the most misunderstood areas of tax deductions.
The issue isn’t knowing that depreciation exists — it’s applying it correctly. Getting this wrong either reduces your refund or creates compliance issues down the track.
Example: Missed Deductions Add Up
A small business owner earning $95,000:
- missed software subscriptions
- underclaimed vehicle usage
- ignored smaller tool purchases
After correcting:
- +$4,000 in tax deductions
That’s not aggressive claiming. That’s just accurate reporting.
ABN vs Employee Deductions
| Area | ABN Business | Employee |
|---|---|---|
| Tools | Broad | Limited |
| Vehicle | Flexible | Restricted |
| Software | Fully deductible | Rare |
| Expenses | Wide | Narrow |
Running a business gives you more control — and more opportunity. But it also means you’re responsible for getting it right.
Employees have restrictions.
ABN holders have exposure.
Record Keeping Drives Everything
If your records are poor, your deductions will be too.
Simple.

No reconstruction. No guessing. No missed claims.
If You’re Guessing Your Deductions
You’re not managing your tax — you’re gambling with it.
You’re either:
- underclaiming and losing money
- or overclaiming and creating risk
Neither is a smart position.
