Testimonials
Rated 5.0 on Google by clients across Sydney. Visited our Miller Street office? We would love to hear how we went.
I have had an excellent experience working with Jenny and Nucleus Accounting.
Jenny provided professional and strategic guidance in establishing
The A&W Richer Pty Ltd and The Richer Family Trust for my investment property structure.
Her knowledge of company and trust structures, compliance requirements, and long-term planning
was evident throughout the process. All documentation was handled efficiently, accurately,
and with a high level of attention to detail. Jenny communicated clearly, acted promptly,
and ensured the structures were set up correctly from both a legal and tax perspective.
I value the quality of advice and professionalism provided and intend to continue working
with Jenny and Nucleus Accounting on an ongoing basis. I would confidently recommend her
services to investors seeking a reliable and well-informed accounting partner.
Jenny and the Nucleus team have been handling my business and personal accounting and taxes for the last three years. I can't thank them enough for the level of service and attention they have provided. I've had accountants before who completely missed what Jenny and her team picked up — saving me so much time, energy, and stress. Highly recommended.
Ju Do and her team at Nucleus Accounting consistently go above and beyond. Every year, tax time feels completely stress-free thanks to their professionalism, efficiency, and attention to detail. They make the entire process smooth and straightforward, and I always feel confident that everything is being handled with care and expertise. I truly appreciate the support and guidance they provide!
I’ve been working with Nucleus Accounting for several years now, and the most impressive part has always been their attention to detail. They don’t just look at the numbers — they genuinely treat my business as if it were their own, always striving to create better impact and more benefits.
As a sole trader, I often have very basic questions, but they always respond with sincerity, clarity, and patience, helping me understand and feel confident in my decisions. Thanks to their support, I can focus on running my business smoothly without worrying about the accounting side of things.
I’m truly grateful for their ongoing assistance and highly recommend Nucleus Accounting to anyone looking for a firm that goes beyond the basics, paying close attention to every detail while genuinely caring about your business success.
I've had tremendous results provided by Jenny and the team regarding both my business and personal tax matters. They’ve delivered a seamless service and have been with me every step of the way, supporting both me and my business.
Thank you to the Nucleus Accounting team for your hard work, dedication, and results. We look forward to working closely with you into the new year!
Whether you run a café in Crows Nest, a consultancy on Walker Street or an investment portfolio from Kirribilli, you need the same four things: the right structure, clean records, lodgements on time and someone who plans ahead with you. Here is how we deliver each one from Miller Street:
Financial statements, company and trust tax returns, BAS and ATO compliance for owner-run businesses in North Sydney.
Personal and business tax returns prepared by a chartered accountant, with tax planning all year, not just before 30 June.
Reconciliations, BAS and monthly reporting in Xero, MYOB or QuickBooks, plus fast catch-ups if you have fallen behind.
Pay runs, Single Touch Payroll, super and NSW payroll tax handled, so your team is paid correctly and on time.
Cash flow forecasting, budgeting and virtual CFO support for established SMEs ready for their next stage.
Self-managed super fund setup, annual accounts, tax returns and audit coordination to keep your fund compliant.
How it works
It depends on how many entities you have (individual, company, trust or SMSF), how organised your records are, whether you need bookkeeping or payroll, and how much advice you want during the year. Here is how we work out your fee:
We learn about your structure, records and goals, at Miller Street or online.
You get a written quote and engagement letter setting out the scope and price.
We look after your accounts, tax and lodgements and keep you updated along the way.
Anything outside the agreed scope is discussed and agreed with you first.
Accounting and tax agent fees are generally tax deductible, so the real cost to you is often lower than the invoice.
Our North Sydney clients range from sole traders to established enterprises in one of Sydney’s busiest commercial centres.
Cafés, clinics, consultants and trades who want an accountant who picks up the phone, explains things plainly and keeps your BAS and tax returns on time.
Consulting, technology, marketing and finance firms around Miller and Walker Streets that need dependable compliance plus forward-looking advice as you grow.
GP, dental and physio practices with service entities, payroll and equipment finance to manage.
Larger organisations and charities that need accurate reporting, governance-ready accounts and payroll handled properly.
If your tax affairs include salary packaging, an employee share scheme, a rental property or overseas income, we handle those every week.
Ownership structures, negative gearing, capital gains tax, GST on property and land tax, set up correctly from the start.
SMSF compliance, retirement income, and the tax rules that apply when you move to or from Australia.
FAQs
It depends on the work involved. An individual tax return costs less than a company or trust return, and ongoing bookkeeping or advisory is usually priced as a monthly package. We start with a free 30-minute consultation, then give you a transparent quote so you know the cost before we start.
Generally, yes. As an individual you can usually claim the cost of managing your tax affairs, including tax agent fees, in the year you pay them. For your business, accounting and bookkeeping fees are normally a deductible expense. We confirm what applies to you when we prepare your return.
We are at 50 Miller Street, North Sydney NSW 2060, on the Lower North Shore just across the Harbour Bridge from the CBD. You can see us on Google Maps. Book ahead so we can set aside time for you.
Yes. There is paid parking in the surrounding streets and nearby car parks. If you prefer public transport, North Sydney station and Victoria Cross Metro are both a short walk away.
Yes. Miller Street is a short trip from all three, and many of our Lower North Shore clients are based there. We can also meet you at your premises where that is easier.
Good times are when you start a business or choose a structure, when you buy an investment property, when your income becomes more complex (shares, rentals, overseas income), when you register for GST or hire staff, or when you fall behind on lodgements and need to catch up with the ATO.
Check that they are a registered tax agent on the Tax Practitioners Board register and a qualified CA or CPA, that they work with businesses or situations like yours, that they give you a clear quote upfront, and that their Google reviews mention responsiveness and clear explanations.
Yes. We regularly catch up overdue tax returns, BAS and bookkeeping, and we can deal with the ATO about penalties or a payment plan while we bring your records back up to date.
