Tax Agent Portal: The Complete Professional Guide (2026)

The Australian Taxation Office (ATO) has replaced the former Tax Agent Portal with Online Services for Agents, a modern and secure platform built specifically for registered tax professionals. It provides a single location where Tax Agents, BAS Agents, and authorised practice staff can manage client tax matters, submit lodgements, access ATO records, and communicate securely with the ATO.

Compared with the previous Tax Agent Portal, the updated platform introduces stronger identity protection through myID and the Relationship Authorisation Manager (RAM). It also offers improved client management, faster access to tax information, enhanced reporting tools, secure digital correspondence, and better practice administration features.

Understanding the Tax Agent Portal

Now known as Online Services for Agents, the Tax Agent Portal is the Australian Taxation Office’s secure online system for registered tax professionals. It enables authorised users to manage client tax information, complete electronic lodgements, review tax accounts, update client details, and securely exchange information with the ATO from a single dashboard.

The platform is designed for:

Registered Tax Agents
Registered BAS Agents
Practice managers and administrators
Authorised employees
Contractors working within registered tax practices

Because the service contains confidential taxpayer information, every user must verify their identity using myID and receive the appropriate business permissions through Relationship Authorisation Manager (RAM) before access is granted.

Before accessing Online Services for Agents, ensure the following requirements have been completed.

1. Hold an Active TPB Registration

Access is available only to professionals who are currently registered with the Tax Practitioners Board (TPB) as either a:

The Australian Government uses myID (previously called myGovID) to confirm your identity when accessing secure government services.

To prepare your account:

Install the myID app on your mobile device.
Register using your personal email address.
Verify your identity documents.
Achieve either a Standard or Strong identity strength.

Identity verification may require documents such as:

A higher identity strength allows access to more government digital services.

3. Connect Your Business Through RAM

Reports and Forms
Accounts
Practice Mail
Communication

Search tools

The dashboard is organised to help practitioners quickly locate client information while maintaining strict security for sensitive tax records.

Managing Clients Through Online Services for Agents

Client management is one of the platform’s core functions. Once a client has authorised your practice, you can administer their tax obligations and access relevant records from a single location.

Adding a New Client

Use the following process to link a new client to your registered practice.

Step 1: Open the Clients Section

From the main navigation menu, select Clients.

Step 2: Select Add Client

Choose Add Client to begin creating a new client relationship.

Step 3: Enter the Client’s Identifier

Search for the client using one of the following:

Tax File Number (TFN)
Australian Business Number (ABN)

Ensure the identifier matches the client’s official records exactly to avoid search errors.

Step 4: Review the Client Information

The system will display the client’s available details.

Confirm that the following information is correct before continuing:

Client name
Business name
Entity type
Identification details

If anything appears incorrect, double-check the TFN or ABN before proceeding.

Choose the tax accounts your practice has permission to manage.

These may include:

Income Tax
Business Activity Statements (BAS)
Goods and Services Tax (GST)
Pay As You Go (PAYG)

Other authorised tax obligations

Step 6: Confirm the Client Relationship

After reviewing the information, finalise the client link.

Once approved, the client will be added to your directory and will be available for ongoing tax management and lodgements.

What Is Agent Nomination?

To strengthen account security, the Australian Taxation Office now requires Agent Nomination for many individuals and businesses before a registered tax practice can be linked.

This additional verification helps ensure only authorised tax professionals gain access to taxpayer information.

How Clients Nominate Their Tax Agent

If Agent Nomination is required, ask your client to complete these steps:

Sign in to their government online account.
Open Online Services.
Go to Profile.
Select Agent Details.
Choose Add Agent.
Search using your Registered Agent Number (RAN).
Submit the nomination request.

Once the nomination has been submitted, your practice has 28 days to add the client.

If that period expires, the client will need to complete the nomination process again before you can proceed.

Lodging Business Activity Statements (BAS) and IAS

Online Services for Agents enables registered practitioners to prepare and lodge both:

Business Activity Statements (BAS)
Instalment Activity Statements (IAS)

Electronic lodgement is generally faster than paper filing and allows agents to review calculations before submitting information to the ATO.

How to Lodge an Activity Statement

Step 1: Locate the Client

Open Clients and search using the client’s:

Name
TFN
ABN

Step 2: Open Activity Statements

Navigate to:

Lodgements → Activity Statements

Step 3: Select the Outstanding Reporting Period

Locate the reporting period listed under Not Lodged, then open the relevant activity statement.

Step 4: Review Existing Information

The system may already contain pre-filled information based on ATO records, including:

PAYG withholding
GST importer details
ATO instalment calculations

Always review every figure carefully before making any edits.

Step 5: Enter Any Required Adjustments

Update the statement where necessary by entering the appropriate figures, such as:

Sales
GST amounts
PAYG adjustments
Other required reporting information

Step 6: Calculate the Outcome

Select Calculate to allow the system to estimate:

Amount payable
Expected refund
Remaining balance

Review the calculated figures to ensure they are accurate.

Step 7: Submit the Statement

Read the declaration carefully.

Tick the declaration checkbox, then select Lodge to submit the activity statement electronically.

After successful submission, the system will display a confirmation that the lodgement has been received.

Using Pre-fill Information

Pre-fill information can significantly reduce manual data entry when preparing client income tax returns.

To view available pre-fill data:

Open Clients.
Select Reports and Forms.
Choose Pre-fill Availability.
Select the required financial year.

Depending on the client, available information may include:

Interest income
Dividend payments
Managed fund distributions
Private health insurance details
Centrelink payment information
Other tax reporting data provided to the ATO

Many practice management systems can import this information directly, helping improve accuracy while saving valuable preparation time.

How Long Does It Take to Become a Registered Tax Agent in Australia?

The time required to become a registered tax agent depends on the qualification pathway you choose. For most applicants, the entire process can take anywhere from 1 to 4 years, although applicants using an experience-only pathway may require significantly longer.

After you have met the education and work experience requirements and submitted a complete application to the Tax Practitioners Board (TPB), the application is generally processed within 30 to 60 days. In some cases, particularly where additional information is required or the application is more complex, processing may take up to the maximum legal timeframe of four months.

Estimated Timeframes by Qualification Pathway

Pathway	Typical Time Required
Accounting Degree	Approximately 1 to 2 years, including at least 12 months of relevant work experience and any Board-approved subjects not already completed as part of the degree.
Diploma Qualification	Around 2 to 3 years, including 2 years of relevant professional experience together with the required Board-approved courses.
Experience-Only Pathway	Applicants without a recognised degree generally need 8 years of relevant experience gained within the previous 10 years, along with completion of specified Board-approved courses.

Start by installing the myID app on your smartphone or tablet. After opening the app, enter your personal information and verify your identity using accepted documents, such as an Australian passport or driver’s licence. To access ATO online services, your Digital ID should have at least a Standard or Strong identity strength.

How to Authorise a Tax Agent for UK Self Assessment

If you want a tax agent to manage your HMRC Self Assessment on your behalf, they must first send you an online authorisation request. HMRC will then email you a secure approval link, often referred to as a digital handshake. To complete the process, sign in using your personal Government Gateway account and approve the request within 21 days.

Authorising an Agent Using the Digital Handshake

The quickest way to grant access is through HMRC’s online authorisation process.

Your agent starts the request. They create an authorisation request using their HMRC online account or compatible tax software.
Watch for the HMRC email. HMRC sends you a secure link to the email address associated with your tax account.
Approve the request. Open the link, sign in with your Government Gateway credentials, and follow the on-screen instructions to authorise your agent.
Complete it within 21 days. The approval link expires after 21 days, so you should confirm the request before the deadline.

Alternative Option: Paper Form 64-8

If you are unable to use the online authorisation process, you can appoint an agent by submitting HMRC Form 64-8.

To use this method:

Download and complete the HMRC 64-8 Authorising Your Agent form.
Enter your Unique Taxpayer Reference (UTR) and your agent’s correct reference details.
Sign and date the form before posting it to HMRC for processing.

The paper method usually takes longer than the digital handshake but remains available for taxpayers who cannot complete the online authorisation process.

Fees you pay to a registered tax agent are generally tax-deductible. If you paid a tax agent to prepare or manage your previous year’s tax affairs, you can usually claim those costs as a deduction on your current year’s tax return. Simply enter the amount you paid under the “Cost of Managing Tax Affairs” section when completing your return.

Final Thoughts

Online Services for Agents, formerly known as the Tax Agent Portal, has become the central digital platform for registered Australian tax professionals. By combining secure identity verification through myID, business authorisation using Relationship Authorisation Manager (RAM), and comprehensive client management tools, it enables tax practitioners to manage compliance efficiently in a secure online environment.

Whether you’re linking new clients, lodging BAS and IAS statements, reviewing pre-fill information, or working across multiple authorised practices, understanding how the platform operates can improve productivity and help maintain compliance with ATO requirements. Keeping your myID current, reviewing RAM permissions regularly, and following recommended security practices will help you make the most of the services available through Online Services for Agents.
