This Tax Deduction Got Rejected Fast: Common Tax Claim Mistakes Australians Make
Learn why tax deductions get rejected,
The most common tax claim mistakes Australians make, and how to stay compliant with ATO rules.
“My mate claims it, so surely I can too.“
It’s one of the most common phrases accountants hear every tax seasonβand one of the biggest reasons taxpayers end up making incorrect claims.
Whether it’s claiming everyday clothing, family pets, home expenses, or personal purchases, many Australians unknowingly rely on advice from friends, colleagues, social media, or previous accountants instead of understanding what the Australian Taxation Office (ATO) actually allows.
In this episode of The Account Rant, Latitude Accountants’ Raymond Semaan and Catarina Santini unpack some of the most common tax deduction myths they encounter when working with Australian individuals and business owners. From wedding photographers disguised as website costs to casino withdrawals recorded as business materials, the conversation highlights how easily taxpayers can make incorrect assumptionsβand why a good accountant’s job is to look beyond what’s written on the transaction.
For Australian business owners, employees, contractors and investors, understanding these rules is essentialβnot only to maximise legitimate deductions but also to avoid unnecessary ATO scrutiny.
What Sparked the Discussion?
Every year, Australians ask the same question:
“Can I claim this on tax?”
The answer is rarely as simple as yes or no.
Throughout the podcast, Raymond and Catarina shared real-life examples of expenses clients attempted to claim, including wedding photography presented as a website cost, casino cash withdrawals categorised as building materials, family pets described as guard dogs, and assumptions that ordinary work clothes automatically qualify as tax deductions.
While these stories may sound humorous, they illustrate a much larger issue.
Many taxpayers genuinely believe that if someone else successfully claimed an expense, they should be entitled to claim it too.
Unfortunately, tax law doesn’t work that way.
Every deduction must be assessed based on the taxpayer’s own circumstances, the purpose of the expense, and whether it satisfies the ATO’s requirements.
Good Accountants Look Beyond the Transaction
One of the strongest themes throughout the episode is that good accountants don’t simply accept a transaction description at face value.
A payment labelled “materials” may turn out to be a casino withdrawal. A website expense may actually be wedding photography. Even something described as a guard dog may simply be the family pet.
Rather than processing transactions without question, experienced accountants dig deeper to understand what the expense was actually for and whether it genuinely relates to earning income.
This investigative approach not only helps clients stay compliant but also ensures their financial records accurately reflect their business activities.
Why This Matters for Australian Taxpayers and Business Owners
Incorrect tax claims don’t always result from deliberate tax avoidance.
More often, they’re caused by misunderstandings.
Australian small business owners frequently receive conflicting advice from friends, industry peers, Facebook groups, or casual conversations. While the advice may be well intentioned, it’s often taken completely out of context.
For example, one industry may legitimately claim an expense because it’s essential to generating income, while another industry cannot claim exactly the same item because it has no connection to their work.
Making assumptions like these can lead to:
- Rejected tax deductions
- Amended tax returns
- Additional tax payable
- Interest and penalties
- Greater ATO scrutiny in future years
The safest approach is always to understand why an expense is deductible rather than simply assuming it is.
Why So Many Tax Deductions Get Rejected
Raymond explains that before any expense can be claimed, it needs to satisfy what he refers to as the three golden rules of tax deductions.
1. The expense must relate to earning your income
This is the most important requirement.
Whether you’re an employee or business owner, there needs to be a clear connection between the expense and how you earn your income.
Personal purchases generally remain private expenses, even if they’re occasionally used for work.
2. You must have paid for the expense yourself
If somebody else paid the expense on your behalfβsuch as your employerβyou generally can’t claim it yourself.
Similarly, expenses paid from business funds need to be correctly recorded to reflect their true purpose.
3. You can’t claim expenses that have been reimbursed
If you’ve already been reimbursed by your employer or another party, you generally can’t claim that same expense again.
Claiming a deduction for something you didn’t ultimately pay for could create compliance issues if reviewed by the ATO.
Different Industries Have Different Deduction Rules
One of the biggest tax myths discussed in the podcast is the belief that everyone can claim the same deductions.
The reality is very different.
One of the funniest observations from the episode is how many tax myths begin with conversations “down at the pub.”
Someone hears that another business owner claimed a particular expense and assumes the same rule applies to them.
In reality, deductions are based on your own occupation, your business activities, and your individual circumstancesβnot what someone else claims on their tax return.
Tax deductions depend heavily on the type of work you perform.
For example:
- A farmer may be entitled to claim expenses relating to a genuine working farm dog because it directly contributes to producing income.
- A security business may have legitimate deductions relating to working guard dogs in specific circumstances.
- A hairdresser, however, generally can’t claim the family pet simply because someone else in another industry could.
The same principle applies across many professions.
Dentists, nurses, tradespeople, accountants, builders, medical professionals and consultants all incur different expenses while earning income.
Rather than comparing yourself to someone in another occupation, it’s far more important to understand how your own expenses relate to your business or employment.
Real Tax Deduction Myths Accountants See Every Year
The podcast featured several memorable stories that demonstrate why accountants often need to dig beneath transaction descriptions before deciding whether something is deductible.
The Wedding Photographer That Became a Website
One client initially asked whether a new website could be claimed as a business expense.
As the conversation continued, it became clear the invoice wasn’t for a website at allβit was for wedding photography.
The lesson?
Changing the description of an expense doesn’t change its tax treatment.
The ATO looks at the true purpose of the purchase, not simply the label attached to it.
Casino Withdrawals Recorded as Building Materials
Another example involved ATM withdrawals made at a casino but recorded within the bookkeeping system as “materials.”
Experienced accountants don’t simply accept account descriptions at face value.
Reviewing supporting information helps ensure financial statements accurately reflect what actually occurred.
Good bookkeeping isn’t just about taxβit also improves financial reporting and business decision-making.
The “Guard Dog” That Was Really the Family Pet
Another client attempted to claim the purchase of a guard dog.
After further discussion, it became apparent the animal was simply the family’s pet.
While genuine working animals may be deductible in limited circumstances, family pets are generally private expenses.
The key question is always whether the expense genuinely relates to producing assessable income.
“My Previous Accountant Claimed It”
This is one of the most common statements accountants hear.
However, previous treatment doesn’t automatically make something correct.
There are many reasons why an expense may have appeared in prior financial statements.
Perhaps additional information wasn’t available at the time.
Perhaps the expense wasn’t actually claimed as a deduction at allβit may simply have been allocated to drawings or a loan account.
Or perhaps the previous adviser formed a different view based on the information they received.
Regardless, every financial year should be assessed on its own facts.
At Latitude Accountants, every deduction is reviewed based on current tax rules, available evidence, and the client’s unique circumstancesβnot assumptions or past practice.
As Raymond explains during the episode, “Whatever your previous accountant did or didn’t do, this is how we run things at Latitude.”
Rather than relying on past practices, the team reviews every client’s circumstances independently, sets clear expectations from day one, and provides advice based on current tax rules and supporting evidence.
Every Client’s Situation Is Confidential
During the discussion, Catarina also explains why accountants cannot confirm what another client has claimed.
Even if someone tells you they successfully claimed a particular expense, a qualified accountant can’t discuss another client’s affairs.
Beyond professional confidentiality, every taxpayer’s circumstances are different, meaning an expense that is deductible for one person may not be deductible for someone else.
Can You Claim Work Clothes?
Another common misconception is that anything worn to work automatically becomes tax-deductible.
Unfortunately, that’s rarely the case.
The ATO generally allows deductions only where clothing falls within recognised categories, such as:
- Protective clothing designed to reduce the risk of injury.
- Occupation-specific clothing unique to a profession.
- Registered or compulsory uniforms that clearly identify an employer.
Simply wearing business attire, office clothing, or smart casual outfits to work doesn’t automatically make those purchases deductible.
Branding also plays an important role.
A registered uniform featuring permanent company logos is treated very differently from ordinary clothing that could just as easily be worn outside work.
Understanding these distinctions helps avoid one of the most common deduction mistakes made each year.
Working From Home Deductions: More Than Just Your Electricity Bill
Working from home has become a normal part of life for many Australians, but it’s also one of the most misunderstood areas of tax.
During the podcast, Raymond and Catarina explained that there isn’t a single “best” method for claiming working-from-home expenses. Instead, the right approach depends on your individual circumstances and whether you can properly substantiate your claim.
Generally, the ATO provides different methods that allow eligible taxpayers to claim running expenses, provided they keep appropriate records of the hours worked and meet the relevant requirements.
For some taxpayers, calculating a fixed-rate claim may be the simplest approach. Others may consider claiming actual running expenses where appropriate.
Rather than automatically recommending one method, Raymond explained that Latitude compares both available approaches wherever possible to determine which provides the better outcome for the client. Just as importantly, the team explains the longer-term implications of each method so clients can make an informed decisionβnot simply choose the largest deduction.
However, claiming occupancy expensesβsuch as a portion of mortgage interest or home ownership costsβrequires careful consideration.
Be Careful When Claiming Part of Your Home
One of the biggest points raised during the discussion was that claiming occupancy expenses can have longer-term implications.
If part of your home is treated as a place of business rather than simply a home office, it may affect the main residence capital gains tax (CGT) exemption when the property is eventually sold.
That doesn’t mean occupancy claims are never appropriate. Rather, taxpayers should understand both the immediate tax benefit and the potential long-term consequences before making a decision.
As Raymond explained, the best approach is to weigh up both available methods, explain the trade-offs to the client, and choose the option that best suits their circumstancesβnot simply the one that produces the highest deduction.
Because every situation is different, professional advice is often worthwhile before deciding which approach to use.
Laundry Deductions Still Require Evidence
One of the lighter moments in the episode came during a discussion about laundry claims.
Raymond shared that he keeps a notebook to record every wash (with a little help from his wife), prompting laughter because very few people actually keep detailed laundry records.
Behind the humour was an important reminder: there is no automatic “$50 laundry deduction.” Like any other tax deduction, laundry claims need to be supported by appropriate records or a reasonable basis for how the claim was calculated. Good substantiation is often the difference between a legitimate deduction and one that may be questioned. Keeping notes, maintaining a simple log, or retaining relevant evidence throughout the year can make tax time significantly easier and help support your claim if it’s ever reviewed.
Why Accurate Record Keeping Matters
Many of the examples discussed in the podcast had one thing in commonβthey started with poor records or incorrect assumptions.
Accurate bookkeeping isn’t just about preparing tax returns.
It helps business owners:
- understand where money is being spent
- identify private expenses correctly
- improve cash flow reporting
- reduce bookkeeping errors
- support legitimate tax deductions
- stay prepared if the ATO requests evidence
When financial records are accurate throughout the year, tax time becomes far less stressful.
Instead of trying to justify expenses months later, business owners already have the documentation needed to support their position.
What Should Business Owners Do Now?
Rather than asking, “Can I claim this?”, business owners should ask a better question:
“Why is this expense deductible?”
Before claiming any expense, consider whether:
- it genuinely relates to earning your income
- you personally paid for it
- you haven’t already been reimbursed
- you have sufficient records to support the claim
- the deduction aligns with your specific occupation or business
If you’re unsure, it’s always better to ask before lodging your return than attempting to fix problems later.
Seeking professional advice early can help maximise legitimate deductions while avoiding unnecessary compliance issues.
Common Mistakes to Avoid
Many tax deduction mistakes are entirely avoidable.
Some of the most common include:
- Assuming a friend’s deduction also applies to you.
- Claiming personal expenses as business costs.
- Believing previous tax returns automatically set a precedent.
- Treating ordinary clothing as deductible workwear.
- Claiming working-from-home expenses without sufficient records.
- Failing to separate private and business transactions.
- Keeping poor bookkeeping records throughout the year.
- Relying on social media tax advice instead of qualified professionals.
Avoiding these mistakes can reduce the likelihood of ATO reviews while giving you greater confidence at tax time.
Frequently Asked Questions
1. Can I claim something because my friend claimed it?
No. Tax deductions depend on your own circumstances, occupation, and whether the expense relates to earning your income.
2. Does my previous accountant’s approach mean I can continue claiming the same expenses?
Not necessarily. Every year should be assessed based on current tax law, available evidence, and your individual circumstances.
3. Can I claim ordinary work clothes?
Generally, no. Ordinary clothing is usually not deductible, even if it’s only worn at work. Limited exceptions apply for protective clothing, occupation-specific clothing, and eligible uniforms.
4. Can I claim branded uniforms?
In many cases, eligible compulsory or registered uniforms may be deductible if you paid for them yourself and meet the relevant ATO requirements.
5. Can I claim laundry expenses?
If you’re washing eligible work-related clothing, you may be able to claim laundry expenses, provided you calculate the claim appropriately and keep suitable records.
6. Can I claim working from home expenses?
Many employees and business owners may be eligible to claim working-from-home expenses if they satisfy the ATO’s requirements and maintain appropriate records.
7. Can claiming part of my home affect capital gains tax?
Potentially. Claiming occupancy expenses for a home used as a place of business may impact the main residence CGT exemption. Professional advice should be obtained before making these claims.
8. What records should I keep for tax deductions?
Keep invoices, receipts, bank statements, logbooks, timesheets, and any documentation that demonstrates how the expense relates to earning your income.
9. What happens if the ATO rejects my deduction?
Depending on the circumstances, you may need to repay tax, interest, or penalties. Maintaining accurate records and seeking advice before lodging can help reduce this risk.
10. Should I ask my accountant before claiming something?
Absolutely. Asking before lodging your tax return is usually much easier than correcting mistakes after the ATO reviews your return.
Final Thoughts
Throughout this episode of *The Account Rant*, Raymond Semaan and Catarina Santini reinforce a simple message: good tax advice isn’t about claiming everythingβit’s about claiming the right things.

By understanding the rules, maintaining accurate records, and seeking professional advice when you’re unsure, you can confidently claim the deductions you’re genuinely entitled to while avoiding costly mistakes.
