Top Accountants In Sydney For 2026

Choosing accountants in Sydney is partly a question of size. A sole trader needs tax returns and BAS handled cleanly, a family business may need structuring and succession advice, and a growing company may need audit, advisory and a firm with national reach. The best fit is the one that matches your stage and answers questions in plain English.

For this list, each firm was checked against its own website. We looked for a Sydney presence and a clear description of accounting, tax or business advisory services. Directories, lead-generation sites and marketplaces were left out, and we only state facts the firms publish themselves. Most firms here are larger practices, and not every site gives a street address.

Accountants In Sydney At A Glance

Best Accountants In Sydney

1. Latitude Accountants — Xero Platinum Partner At Sydney Olympic Park

Latitude Accountants lists its Sydney office at Suite 1.02, Level 1, 5 Murray Rose Avenue, Sydney Olympic Park, and a second office at 207-209 Marrickville Road, Marrickville. The firm says it was founded in 2011 and serves more than 2,000 clients.

Services include accounting, taxation, advisory, superannuation, structural advice and tax planning, along with payroll management, Xero training and Division 7A loan packs. It is a Xero Platinum Partner, and its team profiles list Chartered Accountant designations. The site shows several 2025 and 2026 industry awards, though it does not name every awarding body.

Latitude suits small and mid-sized businesses, sole traders and individuals who want cloud accounting, practical tax planning and a local office rather than a large corporate network.

2. Prosperity Advisers — Business Advisory And Audit Firm With 35 Years Of Experience

Prosperity Advisers lists offices in Sydney, Brisbane and Newcastle and says it has 35 years of experience. Its services are broad: business advisory (including virtual CFO, bookkeeping and payroll), taxation, audit and assurance, international business migration, financial advice, lending, salary packaging and sustainability advisory.

The site names sectors it works with, including health care, hospitality, family business, government, not-for-profit, and innovation and technology. It describes an award-winning record but does not name specific awards.

Prosperity suits owner-managed and family businesses that want accounting, tax, audit and finance advice under one roof. Confirm which services are delivered from the Sydney office before you engage.

3. William Buck — Advisory And Audit Firm With A Sydney Office

William Buck runs ten offices across Australia and New Zealand, and its site links to a dedicated Sydney office page. Services cover audit and assurance, business advisory, corporate finance, restructuring and insolvency, tax, wealth advisory and international business services.

The firm is a member of Praxity, which it describes as the world’s largest alliance of independent accounting firms. Its liability is limited by a scheme approved under Professional Standards Legislation, which is worth noting when you review engagement terms.

William Buck suits mid-sized companies, investors and businesses with overseas links that need audit, tax and advisory services from one firm, but expect a more structured engagement than a small local practice offers.

4. Pitcher Partners — Private Business Advisers With A Sydney Practice

Pitcher Partners has a Sydney practice, with Sydney careers, investment advice and client portal pages on its website, and Sydney partners named in its articles. The firm is a member of the global network of Baker Tilly International.

Its listed services include business advice and improvement, audit and assurance, business recovery and insolvency, business tax, deal advice, digital and data solutions, advice for families, investment advice, personal tax and wealth management. The site does not say which are delivered by the Sydney office, so ask.

Pitcher Partners suits private businesses and families that want a single adviser across tax, transactions and wealth, and that value a firm focused on owner-managed groups.

5. RSM Australia — Tax, Assurance And Consulting With 1,800+ Staff

RSM Australia lists Sydney among its offices, and says it has over 1,800 staff across 32 offices nationally. Services are grouped into assurance, tax, consulting, business services, private wealth and digital solutions such as cyber security and ERP consulting.

The firm cites several Beaton’s Client Choice Awards, including Best Accounting and Consulting Services Firm (over $200m) for seven consecutive years. The site says RSM has been delivering services for over 100 years.

RSM suits larger businesses and groups that need assurance, tax and specialist consulting from a national firm. A very small business will likely find the scale and fees more than it needs.

6. HLB Mann Judd Sydney — Integrated Advisory And Accounting Firm

HLB Mann Judd describes its Sydney office as an integrated advisory and accounting firm with a cost-conscious fee structure. Firm-wide services include advisory, audit and assurance, business services, tax consulting and wealth management.

The firms are members of HLB International, and their liability is limited by a scheme approved under professional standards legislation. The website mentions a 2026 Client Choice Awards win in the firm’s revenue category, though it does not tie that award to Sydney specifically.

It suits businesses that want a combined accounting, tax and advisory relationship and are sensitive to cost. Ask for a written scope and fee estimate for the Sydney team before starting.

7. Moore Australia — Business Advisory And SMSF Services In Sydney

Moore Australia has a Sydney office page and says it has over 600 professionals across 13 offices nationwide. Its services include audit and assurance, taxation, business advisory, corporate finance, ESG reporting, international business, private clients, consulting, and superannuation and SMSF.

Moore Australia is a member firm of Moore Global, which won Network of the Year at the International Accounting Awards 2025, according to the firm’s site. That award relates to the network rather than the Sydney office.

It suits businesses and private clients who want a mid-sized national firm with specialist services such as SMSF and international business support, rather than a small local practice.

8. Nexia Australia — Tax, Audit And Advisory For Private Groups

Nexia’s New South Wales site names Sydney as one of its local offices. Services are grouped under advisory (including family office, forensics and sustainability), tax (for individuals, private business groups and corporate groups) and audit, and it lists sectors such as legal, healthcare and hospitality.

The national site shows Great Place to Work certification badges and a TopAcct25 logo, though it gives no detail on the latter. Liability is limited by a scheme approved under Professional Standards Legislation.

Nexia suits private business groups and professional practices that want tax, audit and advisory support from a firm with an international network behind it.

How To Choose An Accountant In Sydney

Which Qualifications And Registrations Should You Check?

Look for membership of Chartered Accountants Australia and New Zealand or CPA Australia, which set professional and ethical standards. Anyone who charges to prepare tax returns or lodge them for clients should be a registered tax agent with the Tax Practitioners Board, and you can search its public register. Ask which individual will sign your work.

Do You Need A Small Practice Or A Larger Firm?

Smaller practices usually offer direct partner access and lower fees, which suits sole traders and small companies. Larger firms bring specialist teams for audit, transactions and international tax. Match the firm to your complexity: if you only need returns and BAS, a national network may be more than you need.

How Will You Be Charged?

Accountants charge fixed fees for set work such as returns and financial statements, hourly rates for advice, or monthly subscriptions for bookkeeping and BAS. Ask for the scope in writing, what counts as extra, and how often fees are reviewed. Compare like for like, since a low price may exclude payroll or planning.

Do They Work With Your Accounting Software?

If you use Xero, MYOB or QuickBooks, choose a firm comfortable in that system, and ask whether they offer training. Cloud tools let your accountant see figures in real time, which helps with cash flow and BAS. Check how files are shared and who can access your data.

What Support Do You Get Outside Tax Time?

Good accountants talk to you during the year, not only in July and October. Ask how often you will hear from them, who answers questions, and whether planning meetings are included. A firm that flags issues before year end is usually worth more than one that only processes paperwork.

Conclusion

Sydney has accountants for every stage. Latitude Accountants is the clearest pick for small businesses and individuals on cloud software, Prosperity Advisers suits family and growth businesses, and William Buck, Pitcher Partners, RSM, HLB Mann Judd, Moore and Nexia bring the depth of larger networks.

Shortlist two or three, ask each for a written scope and fee estimate, and speak to the person who would actually handle your file.
