⚡ Key Takeaways

  • Australians leave billions in legal deductions unclaimed every year — not through fraud, but through not knowing what they’re entitled to or fear of “getting in trouble” with the ATO. [2]
  • Etax calls union and registration fees one of the top three most-missed deductions — costing mid-career workers $100–$500+ a year without them realising. [2]
  • Many people working from home 2–3 days a week are leaving hundreds of dollars in WFH deductions unclaimed because they think tracking hours is “too hard.” [11]
  • Treasury’s April 2026 exposure draft proposes a $1,000 standard work-expense deduction from 1 July 2026 — but this does NOT apply to your 2025–26 return. You still need to itemise. [6][7]
  • Self-education costs (course fees, textbooks, workshops) linked to your current job are often fully deductible — and one of the most under-claimed categories in the system. [9][10]
  • ATO occupation-specific guides updated in May 2026 list allowable deductions for dozens of jobs — most Australians have never read theirs. [4]

Australian Tax Refund 2026: 7 Deductions You’re Probably Missing

By The Fine Print editorial team  |  Last updated: June 2026  |  11 min read  |  ⚠️ Not financial advice

Australians leave billions of dollars in legal tax deductions unclaimed every year — and it’s not because they’re doing anything wrong. It’s because they don’t know what they’re entitled to, they’re scared of the ATO’s warnings about over-claiming, or the information is spread across so many pages that nobody reads it all. In 2026, the ATO is loudly warning people to stop inventing deductions. But it’s equally clear that if you meet the three golden rules and keep records, you should claim every cent you’re legally allowed — or you’re tipping money back to Canberra for free. [1][2]Here are the seven deductions most Australians under-claim or miss entirely — and exactly what you need to know to claim them correctly this year.

📋 The 7 Deductions

💡 The ATO’s three golden rules — before every deduction

  1. You must have spent the money yourself and not been reimbursed.
  2. The expense must directly relate to earning your income.
  3. You must have records — receipts, logbooks, diary entries — to prove it. [1][4]

💰 Deduction 1: Union, Professional and Registration Fees

Etax lists union and professional registration fees as one of the top three missed deductions in Australia. If you pay union dues, industry registration fees, trade licences or professional body membership fees that relate to your current job, they’re generally deductible under “Other work-related expenses” (D5 in myTax). [2][4]This catches nurses paying ANMF fees, tradies paying their trade association, teachers paying their union, and engineers paying professional body membership — all commonly missed. The dollar amounts range from $100 to $500 or more per year, depending on your industry. That’s not a rounding error; that’s money you’ve already spent that you’re entitled to claim back at your marginal tax rate. [2]
💡 How to claim: Keep the membership invoice or annual fee receipt. In myTax, enter under D5 “Other work-related expenses.” If your employer reimburses the fee, you cannot claim it.

💰 Deduction 2: Work-From-Home (Properly Calculated)

The updated 70c/hour fixed-rate method covers electricity, gas, phone, internet and consumables for time spent working from home. Many people either don’t claim at all or put in a token amount because they think tracking hours is too hard. But all you need is a basic diary or calendar record of actual hours worked from home throughout the year. [8][1]For someone working from home 2–3 days a week, that’s typically 400–600 hours per year — translating to $280–$420 in deductions from the fixed rate alone, before any separately claimable equipment. Many people claim nothing, or claim a round number they picked out of the air. [11]
💡 What to record: A diary, calendar or timesheet showing actual hours worked from home for the full income year (1 July 2025 – 30 June 2026). A sample period is no longer accepted. Also retain bills showing additional phone, internet and energy costs. [1][8]

💰 Deduction 3: Home-Office Equipment and Depreciation

The 70c/hour rate covers running costs — but it does NOT cover the equipment you bought to work from home. Desks, office chairs, monitors, printers, ergonomic gear and dedicated office fit-out can often be claimed separately — either in full (for items under $300 or with an effective life of less than one year) or depreciated over time at their effective life. [10][9]Most employees only claim a phone or internet percentage and never think about the equipment itself. If you bought a $800 monitor, a $400 chair or a $350 desk this year for work use, and you can demonstrate the work-use percentage, that’s potentially hundreds of dollars in deductions you’re walking past. [10][8]
💡 How to claim: Items costing $300 or less with a work-use proportion can generally be deducted in full. Items over $300 are depreciated over their effective life. Keep the purchase receipt and be able to show the work-use percentage (e.g. 80% work, 20% personal use).

💰 Deduction 4: Self-Education and Training Linked to Your Current Job

Self-education is one of the most under-claimed deduction categories in Australia. If a course, conference, subscription or qualification maintains or improves your skills in your current role — or is likely to increase your income in that role — then associated costs can be deductible. This includes course fees, textbooks, some travel to attend, and relevant stationery. [9][10]The ATO’s occupation-specific guides, updated May 2026, list specific examples for dozens of roles. People miss this because they assume only formal university degrees qualify. They don’t. A short online course, a professional development workshop, an industry conference, a technical subscription — if it maintains or improves your ability to do your current job, it’s worth investigating. [4][9]
⚠️ Important boundary: If the course leads to a new career or qualifies you for a completely different field, it generally is NOT deductible. The ATO requires a direct connection to your current employment. When in doubt, check your occupation-specific guide or ask a tax agent.

💰 Deduction 5: Charitable Donations (Over $2, to DGRs)

Donations of $2 or more to registered Deductible Gift Recipients (DGRs) are tax-deductible — but only if you keep receipts. Etax reports that many Australians give to charity and disaster appeals throughout the year but never claim them at tax time, often because receipts were lost, or donations were made via workplace giving, fundraising pages or digital appeals without a clear receipt being saved. [2][9]For regular donors, this can mean hundreds of dollars in missed deductions each year. An annual donation of $50/month to a registered DGR charity is $600 in deductions — worth around $150–$225 at a 25–37% marginal rate, depending on your income. Check whether the charity is a registered DGR using the ATO’s ABN lookup tool before claiming. [2]
💡 How to claim: Gather receipts from DGR charities for 1 July 2025 – 30 June 2026. Enter the total in myTax under “Gifts or donations” (D9). Do not claim donations to non-DGR organisations, crowdfunding campaigns or GoFundMe pages — only registered DGRs qualify.

💰 Deduction 6: Tax-Agent, Accounting and Income-Protection Fees

Two commonly forgotten deductions that sit in plain sight: the fees you paid to prepare last year’s tax return (tax agent, accountant or online tax service), and income-protection insurance premiums — but only if the policy is held outside superannuation. [9][8]Many people forget to claim their previous year’s tax-agent fee because they can’t find the invoice, or don’t realise the current year’s return is the right place to claim it. Others don’t know that income protection insurance outside super belongs in its own deduction label in myTax (D14), separate from life insurance. Missing these is effectively paying extra tax for financial protection you’ve already paid for. [9]
💡 How to claim: Tax-agent fees from your 2024–25 return → D10 “Cost of managing tax affairs.” Income-protection premiums (outside super) → D14 “Income protection insurance.” Do NOT claim life insurance or TPD insurance premiums paid outside super — only income protection qualifies.

💰 Deduction 7: Rental-Property Expenses (Properly Tracked)

For investment property owners, accountants consistently identify the same pattern: the big expenses (mortgage interest, agent fees, rates) get claimed, but the small recurring costs are missed. These include bank fees on the investment loan, body-corporate levies, landlord insurance, repairs and maintenance, and depreciation on capital works and assets. [2][9]Poor record-keeping means landlords often under-claim by hundreds or thousands of dollars, especially when they self-manage the property or receive multiple small invoices across the year. A basic landlord expense spreadsheet — updated monthly as invoices arrive — typically captures $500–$2,000 in deductions that would otherwise be forgotten by July. [2]
⚠️ 2026–27 watch point: Baker McKenzie and other advisers flag that negative gearing and CGT discount changes are in the pipeline, with potential impacts on rental income reporting from 2026–27 onwards. If you own investment property, discuss the upcoming changes with a tax adviser before your 2026–27 return. [Baker McKenzie May 2026]

🔨 Three Actions to Stop Leaving Free Money in Canberra’s Pocket

Action 1: Build a one-page deduction checklist for your job

Go to the ATO’s occupation-specific guides (ato.gov.au → search “occupation guides”) — updated in May 2026 — and find the guide for your industry. It lists the most common deductible expenses for your job: tools, equipment, protective clothing, WFH, car, union fees, training and subscriptions. Print or save it as a one-page checklist and use it year-round to capture expenses as they happen. [4][1][8]

Action 2: Set up a dedicated “Tax 2025–26” folder today

Create an email folder and a cloud folder (Google Drive, Dropbox or iCloud) called “Tax 2025–26.” Every time you make a work-related purchase, receive a union fee invoice, make a charitable donation or pay an insurance premium, forward the receipt directly to that folder. At year-end, you have everything in one place — no scrambling, no guessing, no missing deductions because the receipt was deleted. [14][9]

Action 3: Use myTax’s correct labels — don’t dump everything in “other”

In myTax, use the right category for each deduction: D1 for work-related car expenses, D2 for travel, D3 for clothing and laundry, D4 for self-education, D5 for other work-related expenses (including union fees and small tools). Reserve D5 “Other” for genuinely uncategorised items — don’t use it as a catch-all. Each category has its own ATO guidance and pre-fill prompts, which help you claim correctly and confidently. [8][1]

❓ Frequently Asked Questions

Can I claim union fees on my tax return?

Yes — if they relate to your current job. Union dues, professional body membership fees and industry registration fees all go under D5 “Other work-related expenses.” Keep the invoice. [2][4]

Does the $1,000 standard deduction apply to my 2025-26 return?

No. Treasury’s April 2026 exposure draft proposes a $1,000 instant standard deduction from 1 July 2026 — meaning it applies to 2026–27 returns, not 2025–26. For this year’s return you must itemise every deduction with records. [6][7]

Can I claim a self-education course?

Yes, if the course maintains or improves your skills in your current role, or is likely to increase your income in that role. Course fees, textbooks, some travel and relevant stationery can be deductible. Not deductible: courses for a completely different career. [4][9]

Can I claim income protection insurance?

Yes, if the policy is held outside super and you pay the premiums yourself. Claim under D14 in myTax. Life insurance and TPD insurance (outside super) are NOT deductible. Income protection held inside super is not claimable in your personal return. [9][8]

⚖️ The Fine Print Verdict

The ATO’s computers are now better at detecting what you can’t claim than at telling you what you should. Most Australians overpay tax not because the law is harsh, but because the information is fragmented and the ATO’s warnings about over-claiming have scared them into not claiming things they’re legally entitled to. A 2026 tax return done properly isn’t about pushing the envelope. It’s about finally taking back the deductions the law already gives you — and building a system so you never leave them on the table again.
