Understanding Your Options
Every Australian taxpayer has three main options for lodging their annual tax return. Each has distinct advantages depending on your situation, complexity, and comfort level with tax matters.
Option 1: MyTax (ATO's Free Online Service)
MyTax is the ATO's free online lodgement system, accessible through your myGov account. It's designed for straightforward tax returns and includes:
- Pre-filled information: Income from employers, banks, dividends, government payments, private health insurance details
- Guided questions: Step-by-step prompts to ensure you don't miss anything
- Instant estimate: See your refund/debt as you complete sections
- Quick processing: Refunds typically within 2-12 business days
Option 2: Registered Tax Agent
A registered tax agent is a professional authorised by the Tax Practitioners Board to lodge tax returns on your behalf. This includes:
- Accountants - Full-service tax and financial professionals
- Tax shops - H&R Block, ITP, Tax Smart, etc.
- Online tax agents - Etax, TaxReturn.com.au, etc.
- Bookkeepers - Some are also registered tax agents
Option 3: Paper Form
You can still lodge via paper, but it takes longer (6-8 weeks for refund) and has higher error rates. Only recommended if you have no internet access.
Cost Comparison
| Service | Cost Range | Best For |
|---|---|---|
| MyTax (DIY) | FREE | Simple returns, employees, basic investments |

Tax Agent Fees Are Deductible
You can claim the cost of using a tax agent as a deduction in the following year's return. So a $300 fee effectively costs $210 if you're in the 30% tax bracket.

- ☑ Bank interest and dividends
- ☑ Private health insurance (pre-filled)
- ☑ Government payments (Centrelink, etc.)
- ☑ Standard super contributions
- ☑ One rental property with clear expenses
- ☑ No significant changes from last year
When You Should Use a Tax Agent
Professional help is worth the investment for complex situations:
Consider a Tax Agent If You Have:
- ☑ Self-employment or ABN income
- ☑ Multiple rental properties
- ☑ Sold shares, cryptocurrency, or investment property (CGT events)
- ☑ Foreign income or overseas assets
- ☑ Complex investment portfolios
- ☑ Business income (sole trader, partnership, company)
- ☑ Major life events (separation, death of spouse, inheritance)
- ☑ First time lodging in Australia
- ☑ Previous ATO issues or audits
- ☑ Negative gearing strategies
- ☑ SMSF contributions
The Extended Deadline Advantage
One significant benefit of using a registered tax agent is the extended lodgement deadline:
| Lodgement Method | Deadline | Notes |
|---|---|---|
| MyTax (DIY) | 31 October 2025 | For 2024-25 returns |
| Tax Agent | 15 May 2026 | If registered by 31 October |
Important: Tax Debt Implications
If you owe tax, the extended deadline doesn't extend your payment date. Interest may accrue from 21 November 2025 if you have a debt, even if using an agent. Ask your agent about payment plans if needed.
How to Choose a Good Tax Agent
Check Their Registration
Always verify your tax agent is registered with the Tax Practitioners Board. Search the TPB Public Register before engaging anyone.
Questions to Ask
- What qualifications do you have?
- What's your fee structure? (Fixed fee vs hourly?)
- Do you specialise in my type of return?
- How will you communicate with me?
- What happens if I'm audited?
- Can you help with tax planning for next year?
Red Flags to Avoid
Warning Signs
- ✗ Promises a specific refund before seeing your documents
- ✗ Suggests claiming false or inflated deductions
- ✗ Charges a percentage of your refund
- ✗ Not registered on the TPB register
- ✗ Wants you to sign blank forms
- ✗ Can't provide a written fee estimate
- ✗ Has recent disciplinary actions on record
Hybrid Approach: Get the Best of Both
You don't have to choose one forever. Consider this approach:
- Year 1 - Use a tax agent if your situation is new or complex. They'll set up your return correctly.
- Year 2 onwards - Use MyTax if your situation remains stable. You can copy deductions from previous years.
- Major changes - Use a tax agent again for any significant life events.
Common MyTax Mistakes to Avoid
If you decide to DIY, watch out for these common errors:
1. Forgetting to Add All Income
Don't rely solely on pre-fill. Check bank statements for interest, share dividends not reported, cash work, etc.
2. Over-claiming Home Office
Use the actual or fixed-rate method correctly. Keep a record of hours worked at home.
3. Claiming Personal Expenses as Work
Home to work travel, plain clothes, and personal phone plans are not deductible.
4. Missing Rental Deductions
Don't forget depreciation, borrowing costs, land tax, and property management fees.
5. Incorrect Private Health Insurance Details
Always use the statement from your health fund - don't guess the details.
