Tax Agent Melbourne — Registered Tax Agent for Business & Individual Lodgements

Mina Baselyous is a registered tax agent registered with the Tax Practitioners Board (TPB) and holds two of the highest credentials available to an Australian tax practitioner: Certified Practising Accountant (CPA Australia) and Chartered Tax Advisor (CTA — The Tax Institute). Based in Melbourne, Pinnacle Accounting & Advisory acts as registered tax agent for business owners, company directors, and individuals across Melbourne and Australia.

When you engage Pinnacle as your tax agent, you are not just handing over a tax return. You are engaging a credentialled professional who understands your tax obligations in the context of your broader financial position — and who can legally deal with the ATO on your behalf.

Whether you need a business tax return lodged, ATO correspondence handled, or access to the extended lodgement deadlines that only a registered agent can provide, Pinnacle is equipped to manage your entire tax compliance position from start to finish.

What Does a Registered Tax Agent Do?

Only a registered tax agent — a professional registered with the Tax Practitioners Board (TPB) — can legally prepare and lodge tax returns on behalf of clients for a fee. This is a critical distinction that many business owners overlook.

A bookkeeper, even a qualified one, cannot lodge an income tax return on your behalf. A family friend with accounting knowledge cannot legally act for you in ATO dealings. Only a TPB-registered tax agent has the legal authority and professional obligations to act as your representative with the Australian Taxation Office.

As your registered tax agent, Pinnacle Accounting & Advisory can handle:

• Individual income tax returns — employees, investors, and individuals with complex situations
• Business tax returns — sole traders, companies, partnerships, and trusts
• SMSF annual tax returns and compliance lodgements
• Amended returns — correcting errors or omissions in prior-year lodgements
• ATO audit support — responding to ATO review letters and audit requests
• ATO correspondence and dispute resolution — dealing with the ATO directly on your behalf
• BAS and IAS lodgements — as a registered BAS agent, Pinnacle handles activity statements too

Who Uses Pinnacle as Their Registered Tax Agent?

Pinnacle Accounting & Advisory works with a broad range of clients who need a qualified, reliable tax agent — not just someone to lodge a return, but someone who understands their situation.

• Business owners — sole traders, companies, and trusts wanting one firm to handle both lodgements and proactive tax planning
• Company directors who need to manage multiple entities and meet their obligations under director penalty notice rules
• Individuals with complex returns — investment properties, share portfolios, rental income, side businesses, or foreign income
• Anyone who has received an ATO notice — review letters, audit requests, or payment demands — and needs a qualified agent to respond
• Clients seeking extended lodgement deadlines — registered tax agents have access to the Tax Agent Lodgement Program (TALP), which provides extended deadlines beyond the standard 31 October date
• New business owners starting out who want to structure their affairs correctly from day one

More Than Just a Tax Return

Most tax agents lodge returns and move on. Pinnacle Accounting & Advisory takes a different approach — and that difference starts with Mina’s qualifications.

As a Chartered Tax Advisor (CTA) — The Tax Institute’s highest designation — Mina reviews every lodgement with proactive planning in mind. The question is never just “what tax do you owe this year?” It is “what could be structured differently to reduce what you pay next year?”

This means clients who engage Pinnacle as their registered tax agent benefit from a tax planning lens applied at every lodgement — not just at end of financial year. When your return is prepared by someone with a CTA designation, you have a practitioner who understands the law at a level that goes beyond lodgement.

Qualifications That Matter

Not all tax agents are equal. Credentials matter — and Pinnacle Accounting & Advisory holds dual credentials that are rarely combined in a single practitioner:

• Registered Tax Agent — Tax Practitioners Board (TPB) registration, the legal requirement to lodge tax returns for clients
• Certified Practising Accountant (CPA) — CPA Australia, one of Australia’s most recognised professional accounting designations
• Chartered Tax Advisor (CTA) — The Tax Institute’s highest designation, awarded for advanced expertise in Australian taxation law
• 79+ five-star Google reviews — consistent client satisfaction across business and individual engagements

Tax Lodgement Deadlines in Australia

Understanding lodgement deadlines is one of the practical benefits of engaging a registered tax agent early. The standard income tax return deadline for individuals and businesses is 31 October each year. However, clients who engage a registered tax agent before that date gain access to the Tax Agent Lodgement Program (TALP), which provides significantly extended deadlines.

For many business clients, this means returns can be lodged in January, March, or even May — months after the standard deadline — without incurring ATO late-lodgement penalties. This extension is a genuine, practical benefit of being on a tax agent’s client list before 31 October. For a full overview of key dates for businesses, see our ATO tax key dates guide for 2025–26.

If you are currently self-lodging or using tax software like myTax, you lose access to these extensions. Engaging Pinnacle as your registered tax agent restores that flexibility — and adds the benefit of professional review to every lodgement.

Frequently Asked Questions

What is a registered tax agent?

A registered tax agent is a professional who is registered with the Tax Practitioners Board (TPB) and is legally authorised to prepare and lodge tax returns on behalf of clients for a fee. Registration requires meeting strict education, experience, and ongoing professional development requirements. You can verify any agent’s registration on the TPB public register.

What’s the difference between a tax agent and an accountant?

Not all accountants are registered tax agents, and not all tax agents are accountants. A registered tax agent has met the TPB’s specific requirements to lodge returns on behalf of clients — this is a legal authorisation, not just a professional qualification. Mina Baselyous holds both a CPA accounting designation and a Chartered Tax Advisor designation, and is a registered tax agent — combining all three credentials in a single practitioner.

Can a tax agent help if I receive an ATO audit notice?

Yes. One of the significant advantages of having a registered tax agent is that they can deal directly with the ATO on your behalf. If you receive a review letter, audit request, or payment demand, your registered agent can respond, negotiate, and represent you through the process — something a bookkeeper or financial advisor cannot do.

Do I need a tax agent if I use tax software like myTax?

You can self-lodge simple returns using myTax or similar software. However, for business owners, company directors, those with investment properties, or anyone in a complex tax situation, a registered tax agent significantly reduces the risk of errors, omissions, and ATO scrutiny. You also lose access to the extended lodgement deadlines available through the Tax Agent Lodgement Program when you self-lodge.

How do I check if someone is a registered tax agent?

Check the TPB public register at tpb.gov.au. You can search by name or registration number to verify that any practitioner claiming to be a registered tax agent has current, active registration.

Pinnacle Accounting & Advisory holds a 4.9-star Google rating across 79 reviews — earned through client outcomes, not marketing spend. Here is what clients say about having Mina as their registered tax agent.

Over the years I’ve struggled to find an accountant who can not only do the work but genuinely understands the tax laws surrounding the work. Mina is a true expert in his field — he is able to educate a person who has no knowledge of tax laws.

Mina’s ability to provide round-the-clock advice on the most confusing elements of tax-related topics is impressive.
