Nucleus Accounting is a chartered accounting firm in the Sydney CBD, with a second office in North Sydney. Our team provides tax, accounting and advisory services for established businesses, family groups, professionals and property investors across Sydney.
As your Sydney CBD accountant, we handle individual and company tax returns, tax planning, business accounting, BAS and GST, bookkeeping, payroll, SMSF administration and business advisory, including cash flow and business structure advice. We work with companies, trusts, partnerships and sole traders.
Our principal is a registered tax agent, and our team works with clients through the year, not only at tax time, so lodgements, deadlines and planning opportunities are handled early.
Our Castlereagh Street office sits between Market Street and Park Street, a short walk from Town Hall and St James stations, and serves clients in the Sydney CBD, Haymarket, Surry Hills, Pyrmont, Ultimo, Darlinghurst, Barangaroo and The Rocks.
