Trying to link myGov to ATO but not working? You’re not alone. Many Australians run into this issue, but getting this connection right is essential for managing your tax affairs online. From lodging your annual return to checking your superannuation, a successful link is the gateway to handling your tax obligations efficiently.

This guide provides clear, step-by-step instructions for linking your accounts, along with practical fixes for the most common errors.

Quick Fixes for myGov ATO Linking Issues

• Can’t link? You’ll need your TFN and two pieces of information (e.g. Notice of Assessment or super details) that match ATO records exactly.
• Identity verification failing? Ensure your name and DOB in myGov match ATO records perfectly (including middle names).
• Need a linking code? Call the ATO on 13 28 61 to get a 24-hour linking code.
• myGov account locked? Use account recovery or contact the myGov helpdesk.
• ATO missing from myGov? The link has broken, relink via the ‘Services’ page.
• Still stuck? You may need help from a tax professional.

Why Linking Your myGov and ATO Accounts Is Essential

InIn Australia, linking myGov to the ATO is now standard for millions of taxpayers managing their affairs online. This connection is important not just for convenience, but also for security and compliance.

Once linked, you can:

• Lodge your tax returns
• Manage Business Activity Statements (BAS)
• Check your superannuation balances
• Track employment income and PAYG instalments
• Update your personal details with the ATO

Digital access is now the norm. In recent years, over 90% of Australian tax returns are lodged electronically, either through myGov or registered tax agents.

How to Link ATO to myGov Account

Connecting your ATO and myGov accounts should be straightforward, but it requires careful preparation. Follow these steps to get it done right the first time.

Before you start, ensure your myGovID app shows at least a ‘Standard’ identity strength. A ‘Basic’ strength is not sufficient to link to the ATO.

1. Log in to myGov: Go to the official myGov website (my.gov.au) and sign in using your username, password, and the security code sent to your phone or generated by the myGovID app.
2. Navigate to Services: On your myGov home screen, find the ‘Your services’ section and click the ‘Link another service’ button.
3. Select the ATO: From the list of available government agencies, choose the Australian Taxation Office.
4. Agree to Terms: You will be prompted to agree to the terms of use. Read them and click ‘I agree’ to proceed.
5. Provide Your TFN: Enter your Tax File Number (TFN). Double-check it for accuracy before continuing.
6. Verify Your Identity: This is the most critical step. You must provide two specific pieces of information that exactly match the ATO’s records for you.

To avoid myGov login issues, gather your documents before you start. The details you provide must match what the ATO has on file for you, character for character. You can learn more directly from the ATO’s guidance on creating and linking your myGov account.

Information You Need for ATO Identity Verification

Have two of the following documents ready. You must use information from two different sources.

Information Type	Details Required	Common Pitfall to Avoid
Notice of Assessment	The date of issue and the “Our reference number”.	Using a notice older than five years.
PAYG Payment Summary	The total gross income amount (in whole dollars).	Using a summary older than two years.
Superannuation Account	The fund’s ABN and your member account number.	Using an inactive or closed super account.
Bank Account Details	The BSB and account number where you recently received an ATO refund.	Entering details of an account the ATO has never paid a refund into.
Centrelink Payment Summary	The taxable income amount from your summary.	Using a summary from more than two years ago.

Once you’ve successfully entered two matching details, the link will be complete. The ATO will appear under your ‘Linked services’ on the myGov homepage.

If you are a new taxpayer or don’t have enough history to provide these documents, you’ll need an ATO linking code. Our guide on what to do when you need an ATO linking code breaks down exactly how to get one.

Remember: System processes can change. Check current ATO or myGov guidance if you encounter any issues.

Troubleshooting: Common myGov and ATO Linking Issues and Fixes

Hitting an error wall trying to establish your myGov ATO login link? It’s a notoriously finicky process, but most error messages are straightforward to solve once you know the cause. Let’s fix the specific issues that trip people up most.

Issue 1: Identity Verification Failure (Error: A951.22)

This is the most common hurdle. It means the details you entered don’t exactly match what the ATO has on file. A staggering 1 in 5 Australians face problems linking myGov to the ATO due to tiny mismatches.

• The Cause: Mismatched names (e.g., “Jon” vs “Jonathan”), an old address, or using information from a document not linked to your personal TFN (like a business bank account).
• The Fix: Do not re-enter the same information. Stop and cross-reference your myGov profile details (full name, date of birth) with your official ATO documents. If your name has changed, you must update it with the ATO before you can link your accounts. Use a different combination of verification documents, like a Notice of Assessment and a super statement.

Issue 2: ATO Linking Code Has Expired or Is Invalid

An ATO linking code is a temporary, single-use code that is only valid for 24 hours.

• The Cause: You waited too long to use the code, or you entered it incorrectly.
• The Fix: You must call the ATO again to request a new one. Before you call, have all your identity documents ready so you can complete the linking process immediately after you hang up.

Issue 3: The ATO Has Vanished from Your Linked Services

Sometimes the link between myGov and the ATO can break, often after a system update or if you haven’t logged in for a long time.

• The Cause: A system sync error or account inactivity.
• The Fix: Go to the ‘Your services’ page in myGov. If you see an option to ‘Link’ the ATO where it should be listed as a connected service, the connection is gone. You will have to go through the linking process again. Our guide on ATO call verification processes can help if you need to confirm details over the phone.

Issue 4: Your myGov Account is Locked

If you enter your password or secret question answers incorrectly too many times, myGov will lock you out for security.

• The Cause: Too many failed login attempts.
• The Fix: Use the “Forgot your password” or “Recover your account” options on the myGov login page. You will need to answer your secret questions or use your myGovID app to regain access. If you are completely stuck, you must call the myGov helpdesk. Procedures can change, so always check current myGov guidance.

Worked Example: How to Fix a Failed ATO Link

Let’s walk through a common scenario to see these fixes in action.

Meet Priya, a sole trader trying to link her myGov and ATO accounts for the first time. She’s sure she has the right info but keeps hitting the frustrating ‘Unable to verify’ error.

The Initial Attempt and the Mistake

Priya logs into myGov, navigates to the ATO linking section, and enters her TFN. For her two identity documents, she uses:

1. Details from a recent superannuation statement.
2. Her business bank account details, where her last tax refund was paid.

The system accepts the super details but rejects her bank details.

The Problem: Priya’s tax agent lodged her last return, and the refund was paid into her business account. However, the ATO’s primary record for her as an individual taxpayer does not have that business bank account listed. The system is looking for a match on her personal file, not a business one. This mismatch causes the myGov identity verification to fail.

Finding the Right Information and Succeeding

Priya thinks back. Before starting her business, she worked a part-time job. She finds her PAYG payment summary from that employer.

She tries the linking process again with a different combination:

1. Her recent superannuation statement details.
2. The gross income amount from her PAYG payment summary.

Success! Because both documents are tied directly to her personal TFN record, the system finds a perfect match. The myGov ATO login link is now active.

Priya’s experience is a classic example of why you must use information the ATO already associates with your individual tax file. Always check the current ATO or myGov guidance for the right documents to use.

Your myGov ATO Linking Checklist

Before you hit that ‘link’ button, run through this quick checklist to ensure you have everything needed for a smooth, one-and-done setup. Spending five minutes here can save you an hour of frustration.

•  Check Your myGovID Strength: Open your myGovID app. You must have at least a ‘Standard’ identity strength. A ‘Basic’ strength will not work for linking to the ATO.
•  Have Your TFN Ready: Find your Tax File Number (TFN) and write it down. A single wrong digit will cause an instant failure.
•  Gather Two Key Documents: You’ll be asked to verify your identity. Grab two approved documents, such as a recent Notice of Assessment, your PAYG payment summary, or a superannuation statement.
•  Ensure Your Details Match Perfectly: The full name and date of birth in your myGov profile must be an exact match to what the ATO has on record. A missing middle initial or a typo will block the connection. Check your myGov profile settings first.
•  Use a Secure Connection: Only use a private, secure internet connection, not public Wi-Fi, when accessing your tax information.

Common Mistakes and How to Fix Them

• Mistake: Using a business bank account for individual identity verification.
  • Fix: Use personal bank account details that the ATO has previously paid a personal tax refund into, or use another document type like a Notice of Assessment.
• Mistake: Name in myGov doesn’t match the ATO’s records (e.g., maiden name vs. married name).
  • Fix: Before linking, update your name with the ATO first. You cannot link accounts with mismatched names.
• Mistake: Entering information from an old document (e.g., a PAYG summary from three years ago).
  • Fix: Only use documents from within the specified timeframes (e.g., within the last two years for a PAYG summary or five years for a Notice of Assessment).
• Mistake: Trying to link with a ‘Basic’ myGovID identity strength.
  • Fix: Open the myGovID app and upgrade your identity strength to ‘Standard’ or ‘Strong’ by verifying more documents like your driver’s licence or passport.

When to Get Expert Help with Your Tax Affairs

Sometimes a myGov linking error isn’t just a technical glitch; it’s a symptom of a bigger problem with your tax affairs. Knowing when to stop wrestling with the system and call a professional can save you time, stress, and potential ATO penalties.

If you’ve tried every troubleshooting step and you’re still locked out, it’s a red flag.

When to Call in a Professional

It’s time to get an expert involved if you’re facing any of these roadblocks:

• Ongoing Linking Errors: You’ve tried every fix, but the system flat-out refuses to connect your myGov and ATO accounts. This could point to a data integrity issue on the ATO’s end.
• Complex Tax Situations: You’re not just a standard employee. You might be running a business, managing a trust, have a Self-Managed Super Fund (SMSF), or require help with a company setup.
• Overdue Lodgements: You have one or more tax returns or BAS statements outstanding. This often complicates the ATO’s identity verification process and can block your online access.
• ATO Notices or Debt: You’ve received a letter from the ATO about an audit, an outstanding debt, or another compliance issue. Don’t ignore it.

Don’t let a small login problem snowball into a major tax headache.

Frequently Asked Questions

How do I link ATO to myGov?

To link the ATO, log in to myGov, go to ‘Services’, select ‘Australian Taxation Office’, and follow the prompts. You will need to provide your TFN and two specific pieces of information, such as details from a Notice of Assessment or superannuation account, to verify your identity.

Why can’t I link my ATO account to myGov?

The most common reason is that the identity information you provide does not exactly match the ATO’s records. This includes your name, date of birth, and the details from your verification documents. Ensure your myGovID is at a ‘Standard’ strength and that all details are 100% correct.

What is an ATO linking code and how do I get one?

An ATO linking code is a temporary, 24-hour code used to verify your identity when you can’t use online documents. You can only get one by calling the ATO on 13 28 61 and answering security questions over the phone.

What if my myGov account is locked?

If your myGov account is locked due to too many incorrect password attempts, use the account recovery options on the login screen. You may need to answer your secret questions or use your myGovID app. If you are still unable to get in, you must contact the myGov helpdesk for assistance.

Can I access ATO online services without myGov?

No. For individuals and sole traders, myGov is the only way to access ATO online services. The old methods of logging in directly to the ATO have been phased out, making the myGov ATO login link a mandatory step for digital tax management.

What identity strength do I need for myGov to link to the ATO?

You must have a minimum of ‘Standard’ identity strength in your myGovID app to link to the ATO. A ‘Basic’ strength is not sufficient. You can increase your identity strength by verifying official documents like your driver’s licence or passport within the app.

My details are correct but the linking still fails. What should I do?

If you are certain all your details are correct, there may be an issue with your ATO record itself. This is the point where you should stop and either call the ATO for help or engage a tax agent who can investigate the problem on your behalf.

What should I do if I suspect my myGov or ATO account has been compromised?

If you notice suspicious activity, immediately contact the ATO’s Client Identity Support Centre and the myGov helpdesk. It’s also wise to report the incident to the Australian Cyber Security Centre. Read more about protecting yourself from ATO identity theft issues.
