  • Medicare levy exemption: If applicable (visitors, foreign residents)

Step 1: Set Up Your myGov Account

If you don't already have a myGov account, you'll need to create one. myGov is the Australian Government's secure online portal that links to various government services including the ATO.

Creating a myGov Account

  1. 1
    Go to my.gov.au

    Visit the official myGov website

  2. 2
    Click "Create an account"

    Enter your email address and create a password

  3. 3
    Verify your email

    Check your inbox and click the verification link

  4. 4
    Set up security questions

    Choose questions and answers for account recovery

  5. 5
    Set up myGov Code Generator (recommended)

    Download the myGov Code Generator app for secure login

Once you have a myGov account, you need to link it to the ATO. This is a one-time process that gives you access to MyTax and other ATO online services.

Linking to ATO

  1. 1
    Log into myGov

    Use your email and password or myGov Code Generator

  2. 2
    Click "Link services"

    Find this in the Services menu

  3. 3
    Select "Australian Taxation Office"

    Choose ATO from the list of available services

  4. 4
    Verify your identity

    You'll need 2 of the following:

    • • Notice of assessment from a previous year
    • • Bank account details linked to ATO
    • • Super account details
    • • Centrelink payment summary
    • • PAYG payment summary

First Time Linking?

If you're new to Australia or haven't lodged before, you may need to call the ATO on 13 28 61 to get a linking code. Have your TFN and identity documents ready.

Step 3: Access MyTax and Start Your Return

Now you can access MyTax and begin your tax return. The ATO pre-fills most of your information, but you should check everything carefully.

Starting Your Tax Return

  1. 1
    Click on "ATO" in myGov

    This opens ATO Online Services

  2. 2
    Select "Tax" then "Lodgements" then "Income tax"

    Navigate to the tax return section

  3. 3
    Click "Lodge tax return"

    Select the financial year (e.g., 2024-25)

  4. 4
    Wait for pre-fill to load

    This can take a few moments. Pre-fill includes employer income, bank interest, dividends, and health insurance

Wait for Your Income Statement

Your employer must finalise your income statement by 14 July each year. If you lodge before this, your pre-fill may be incomplete. Check that your income statement shows "Tax ready" before lodging.

Step 4: Review Your Pre-Filled Income

MyTax pre-fills income from various sources. Review each section carefully and add any missing information.

Types of Pre-Filled Income

Income Type Source Check For
Salary & wages Employer income statements All jobs listed, amounts match payslips
Bank interest Banks & financial institutions All accounts included
Dividends Share registries Franking credits included
Government payments Centrelink All payments and tax withheld
Private health Health insurers Days covered, rebate tier

Important: Check All Pre-Fill Data

Don't assume pre-fill is complete or correct. You are responsible for the accuracy of your tax return. Common issues include:

  • • Missing casual or part-time jobs
  • • Incomplete bank interest (some accounts not reported)
  • • Crypto/share income not pre-filled (you must add manually)
  • • Rental income not pre-filled (you must add manually)

Step 5: Claim Your Deductions

Deductions reduce your taxable income, which means you pay less tax or get a bigger refund. Only claim deductions you're entitled to and can support with records.

Common Work-Related Deductions

Car and Travel

  • Cents per km: Up to 5,000 km at 88c/km (2024-25)
  • Logbook: If over 5,000 km, need 12-week logbook
  • Travel between jobs: Can claim full cost
  • Home to work: Generally NOT deductible

Working From Home

  • Fixed rate: 67c per hour (2024-25)
  • Actual cost: Calculate real expenses
  • Records needed: Diary of hours worked
  • Includes: Electricity, internet, phone

Clothing and Laundry

  • Compulsory uniform: Full cost deductible
  • Protective clothing: Safety gear, boots
  • Laundry: $1 per load (up to $150 no receipts)
  • Everyday clothes: NOT deductible

Tools and Equipment

  • Under $300: Immediate deduction
  • Over $300: Depreciate over useful life
  • Phone/laptop: Work-use percentage only
  • Keep receipts: For 5 years

Other Deductions

  • Self-education: Courses directly related to your current job
  • Union fees: Professional association memberships
  • Tax agent fees: Previous year's tax agent costs
  • Income protection insurance: Premiums you pay (not via super)
  • Donations: To registered charities ($2+ with receipt)

$300 No-Receipt Threshold

If your total work-related deductions are $300 or less, you don't need receipts. However, you must still have actually spent the money on work-related items. The ATO can ask you to show how you calculated your claim.

Step 6: Check for Tax Offsets

Tax offsets (also called rebates) directly reduce the tax you pay. MyTax will automatically apply some offsets based on your income and circumstances.

Offset Who Qualifies Maximum Value
Low Income Tax Offset (LITO) Taxable income under $66,667 Up to $700
Low and Middle Income Tax Offset Ended 30 June 2022 No longer available
Private Health Insurance Rebate PHI holders below income threshold 8.202% - 32.812% of premium
Seniors and Pensioners Tax Offset Age pension recipients Up to $2,230

Step 7: Medicare Levy and Surcharge

Most Australian residents pay the Medicare levy of 2% of their taxable income. You may also need to pay the Medicare Levy Surcharge if you earn above certain thresholds and don't have private hospital cover.

Medicare Levy Exemptions

  • Low income: Full exemption if income below $26,000 (single)
  • Foreign residents: Not entitled to Medicare benefits
  • Certain visa holders: With no Medicare access

Medicare Levy Surcharge (MLS)

If your income is over $93,000 (single) or $186,000 (family) and you don't have private hospital cover, you'll pay an extra 1% - 1.5% surcharge. Getting basic hospital cover is often cheaper than paying MLS.

Step 8: Review and Lodge

Before lodging, MyTax shows a summary of your tax return including your estimated refund or tax payable.

Final Checklist Before Lodging

  • All income sources included and correct
  • Deductions are accurate and I have records
  • Bank account details for refund are correct
  • Spouse details (if applicable) are correct
  • Private health insurance details checked
  • Estimated refund/payable looks reasonable

Click "Lodge" to submit your tax return. You'll receive a confirmation and your Notice of Assessment will be available in myGov within 2 weeks (usually faster if lodging electronically).
