If tax deductions were as generous as some people hope, edible underwear, gaming consoles and designer wardrobes would all be “essential work tools.” 

Unfortunately, the ATO isn’t quite that imaginative – and every year, it knocks back a long list of claims that are more wishful thinking than legitimate deductions. While some are amusing in hindsight, others can attract unwanted ATO attention and lead to penalties or amended assessments.

Let’s take a look at some claims that don’t pass the test, and what can legitimately be claimed instead.

Claims That Don’t Make the Cut

One of the most common myths is that everyday clothing is deductible. Claims for suits, business attire, activewear, or even luxury handbags worn “for work” are regularly denied. If the clothing is suitable for everyday wear, it generally isn’t deductible — no matter how professional it looks.

Another red flag is attempting to claim family holidays as work travel. Adding a conference or client coffee to a beach getaway doesn’t automatically make flights, accommodation, and meals deductible for the whole family. The ATO looks closely at whether travel was genuinely for work and how expenses are apportioned.

Some people also try to claim pets as security expenses, arguing that a dog protects a home office. Unfortunately, unless the animal is specifically trained and used for business security purposes, this type of claim is unlikely to succeed.

Then there are exaggerated claims for home office expenses, such as trying to deduct the entire mortgage, rent, or utility bills simply because some work is done at home. Without a dedicated workspace and proper records, these claims won’t stand up.

What Does Make the Cut?

The good news is that many legitimate deductions are often overlooked.

Work-related expenses that are directly connected to earning income can usually be claimed, provided you have records. This includes tools, equipment, professional subscriptions, union fees, and work-related phone or internet usage (apportioned correctly).

For those working from home, home office deductions may be available for electricity, internet, and depreciation on office furniture — but only for the work-related portion and using an accepted calculation method.

Education expenses can also be deductible when the course maintains or improves your current skills or is directly related to your role. However, courses that help you move into a new career generally don’t qualify.

The Bottom Line

If a claim feels like a stretch, it probably is. The ATO expects deductions to be reasonable, well-documented, and genuinely related to earning income. When in doubt, getting advice before lodging can save you from costly mistakes — and help ensure you only claim what you’re entitled to, and nothing more.
