Common Tax Deductions Individuals Miss Each Year
When tax time comes around, most people focus on the obvious things: their salary, bank interest and any investments they've earned income from. But what about the expenses they've paid throughout the year?
A professional membership, part of your home internet bill or the cost of having last year's tax return prepared might seem insignificant. Yet, if an expense is genuinely tax-deductible, forgetting to claim it could mean paying more tax than necessary.
The trick isn't to claim every expense you can think of. It's to identify the expenses that relate to earning your income, keep the right records and make sure your claims comply with Australian Taxation Office (ATO) rules.
Here are some commonly overlooked tax deductions for Australian individuals, along with practical tips to help you avoid missing out.
First, understand how tax deductions work
A tax deduction reduces your taxable income. It doesn't reduce your tax bill dollar for dollar.
For example, if you're eligible to claim $800 in work-related expenses and your marginal tax rate is 30%, the deduction could reduce your tax by $240, assuming the relevant circumstances remain the same.
Before claiming an expense, ask three questions:
Did you pay for the expense yourself?
Was it connected to earning your assessable income?
Can you support the claim with appropriate records?
If an expense was partly private and partly work-related, you can generally claim only the work-related portion. You also need a reasonable way to calculate that portion.
Tax rules, rates and thresholds can change, so check the ATO's guidance for the relevant income year before lodging your return.
1. Home office expenses
Working from home can involve more deductible expenses than you might realise.
Depending on your circumstances, eligible running costs may include electricity, heating, cooling, internet, phone expenses, stationery and computer consumables. Work-related equipment may also qualify for a deduction or depreciation.
The ATO provides different methods for calculating home office running expenses, including a fixed-rate method and an actual-cost method. The requirements differ, so don't assume the same approach suits everyone.
The biggest trap is record-keeping. You need to keep appropriate evidence of the hours you actually worked from home and records supporting the expenses you claim. Estimates made from memory at tax time may not be enough.
If you work from home regularly, compare the available methods before deciding which one to use.
Remember that working from home doesn't automatically make your rent, mortgage interest, council rates or home insurance deductible. Occupancy expenses have separate rules, particularly for employees.
2. Self-education and professional development
Have you paid for a course, conference or professional subscription to improve your skills at work?
Some education expenses may be deductible when they maintain or improve skills used in your current employment, or are likely to increase your income from that employment.
For example, a nurse undertaking further nursing training has a clear connection between the course and their existing work. Studying for an entirely different career does not qualify.
Depending on the circumstances, eligible expenses can include course fees, textbooks, professional journals, relevant travel and conference registration.
However, not every education expense is deductible. HECS-HELP repayments, for example, are repayments of a student loan rather than deductible education expenses.
Before claiming a course, consider how it relates to your current income and retain the invoices and other supporting records.
3. Work-related travel and vehicle expenses
Your everyday trip between home and your usual workplace is considered private travel. However, other work-related journeys may qualify.
Examples can include travelling between separate workplaces, driving from your office to a client, or travelling to a temporary work location in eligible circumstances.
If you use your own car for work, the ATO provides different methods for calculating eligible car expenses. The cents-per-kilometre method is simpler, while the logbook method involves recording your business use and calculating the appropriate proportion of vehicle expenses.
The best option depends on your circumstances and the records you have available.
Keep in mind that carrying tools or equipment doesn't automatically make your ordinary commute deductible. Specific conditions apply, including rules around bulky equipment.
4. Income protection insurance premiums
If you pay for income protection insurance, the premiums may be tax-deductible because the policy protects your income.
This is an easy deduction to overlook when premiums are automatically taken from your bank account.
Check your annual insurance statement to see what you've paid and what portion relates to income protection. If your policy combines different types of cover, ask your insurer for a breakdown.
Life insurance, trauma insurance and total and permanent disability (TPD) premiums generally aren't deductible to an individual in the same way.
You also generally can't claim premiums paid through your superannuation fund as your personal deduction. Check how your policy is held before including anything in your return.
5. Personal superannuation contributions
Making personal contributions to super may offer a tax deduction if you meet the relevant requirements.
However, contributing money isn't enough on its own. You generally need to give your super fund a valid notice of intent to claim a deduction and receive its acknowledgement within the required timeframe.
If you miss the relevant requirements, you may lose the deduction. Certain rollovers, withdrawals or changes to your super account can also affect whether a notice remains valid.
Contribution caps and eligibility rules apply, including rules around unused concessional contribution caps from previous years.
If you're considering a personal super contribution to manage a high-income year or a capital gain, check the rules before acting. You can read more in our article on how concessional and non-concessional contributions work together.
6. Work equipment, tools and software
Laptops, phones, tablets, tools, protective equipment and software subscriptions may qualify for deductions when they're used to earn your income.
The tax treatment depends on the item, its cost, how it's used and the applicable rules. Some eligible lower-cost items may be deductible immediately, while other assets need to be depreciated over time.
A common mistake is claiming the initial cost of an asset but forgetting that depreciation deductions may continue in later years.
Here are some general examples:
Work tools and devices: Keep purchase receipts and records of work-related use.
Computers and other equipment: Check whether depreciation applies.
Protective clothing: Ordinary clothing generally doesn't qualify simply because you wear it to work; specific rules apply to protective clothing and eligible uniforms.
Software subscriptions: Keep invoices and claim only the eligible work-related portion.
Don't rely on an item's price alone to determine its tax treatment. Check the rules that apply to the relevant income year.
7. Union fees and professional memberships
Small recurring expenses can be surprisingly easy to forget.
Union fees, professional association memberships, eligible registration renewals and subscriptions to work-related publications may be deductible when they relate to your current employment or income-producing activities.
The same may apply to certain software subscriptions and professional indemnity premiums you pay personally.
A simple habit can help: save renewal emails and receipts in a dedicated folder throughout the year. That way, you aren't trying to remember every payment when your tax return is due.
General-interest subscriptions don't automatically qualify. There needs to be a sufficient connection to earning your income.
8. Interest and expenses on investments
If you borrow money to acquire income-producing investments, the interest may be deductible to the extent the borrowing is used for that purpose.
Other eligible expenses associated with managing investments may also qualify, depending on the circumstances.
The important issue is how the money is used. If an investment loan is also used for private expenses, you may need to apportion the interest. Keeping investment and private borrowings separate can make the records easier to manage.
Property investors should also check whether they have claimed eligible capital works deductions and depreciation. A quantity surveyor's report may help identify deductions, although the outcome depends on the property and applicable rules.
9. Charitable donations
Genuine donations to organisations with deductible gift recipient (DGR) status may be deductible, provided the relevant requirements are met.
But not every payment made at a charity event qualifies. If you receive something in return, such as a raffle ticket, dinner or auction item, the payment may not be a deductible gift.
Check the organisation's status and keep your donation receipt.
If you donate through workplace giving, check how the donation has been treated through payroll. You don't want to claim the same amount twice.
10. The cost of preparing your tax return
Here's one that can easily slip through the cracks: the cost of managing your tax affairs.
Eligible expenses may include fees for preparing and lodging your tax return, tax-related advice and certain costs associated with objections or appeals.
The deduction is generally claimed in the income year the expense was incurred or paid, as applicable to the relevant rules. So, a fee paid this year for last year's return may belong in this year's deductions.
Keep your accountant's invoice with your other tax records. You can find details of our individual tax return services and pricing if you need help with your own return.
Keep records throughout the year
Good record-keeping makes claiming legitimate deductions much easier.
Rather than waiting until June or July, try these simple habits:
Save receipts and invoices when you receive them.
Keep a record of work-related use for items that also have a private purpose.
Record work-from-home hours and eligible business travel as you go.
Keep records for the required retention period, generally five years for many individual tax records, with longer periods potentially applying in some circumstances.
Make a note explaining unusual expenses while you still remember why you incurred them.
The ATO's pre-fill information can help with income and other details, but it won't necessarily identify every expense you paid. You still need to check your own records.
Frequently asked questions
Can employees claim home office expenses?
Yes, eligible running expenses may be deductible where you genuinely work from home and meet the relevant requirements. You need to follow the record-keeping rules for the method you use. Private occupancy expenses generally aren't deductible for employees simply because they work from home.
Do I need receipts for every deduction?
You should keep records to substantiate your claims. Some limited concessions apply to particular expenses, but the rules differ by claim type. Check the ATO's current requirements rather than assuming that a bank statement or a total below a particular threshold is always sufficient.
Can I claim an expense I forgot about last year?
You can't simply add a previous year's expense to your current return. If you missed an eligible deduction, you may be able to request an amendment to the original assessment. Time limits depend on your circumstances, so check the applicable rules.
Do tax deductions guarantee a refund?
No. A deduction reduces taxable income, but whether you receive a refund depends on your overall tax position and how much tax you've already paid or had withheld.
Don't leave legitimate deductions behind
Most missed deductions aren't the result of complicated tax strategies. They're often everyday expenses that weren't recorded properly or weren't considered when the return was prepared.
A little organisation can make a difference. And if your finances include investments, superannuation, rental property or a side business, it may be worth looking beyond individual receipts to make sure your tax affairs are being managed appropriately.
