A chartered accounting firm in Caringbah, Sydney, serving businesses and individuals since 1987

Australian accounting practice offering tax returns, business advice, compliance and SMSF support for small businesses

Founded in January 2000, A. Costa & Associates is run by accountants and business advisers in Australia. A small group of accountants set it up just after the goods and services tax arrived in Australia, expecting that small businesses would need regular information and support well beyond the work of a simple tax return accountant. The practice was built around that idea, with processes to keep clients informed and access to information from the Australian Taxation Office and other sources.
The firm organises accounting and tax returns in an efficient and orderly way, in line with the requirements of the Australian Taxation Office. Its compliance work covers recording and reporting, so that a business keeps its records well structured and documented, and its owners can concentrate on running the operation rather than on paperwork.
For clients who want more control over their retirement savings, the practice helps with Self Managed Superannuation Funds. That includes keeping up with the obligations that come with running a fund and planning how to make the most of superannuation over time.
The advisory side begins with what a client is trying to achieve, and then shapes its input around those outcomes. The firm's stated goal is to help a business become more competitive, focused and profitable, and to grow efficiently and effectively. Advice covers financial, taxation and business questions, with services set up to suit the way each client wants to work.
The firm publishes articles and updates on matters that may affect clients, covering topics such as the difference between leasing a car and taking it on hire purchase, the way interest rate changes affect household finances, the tax treatment of staff benefits at Christmas, cash flow forecasting, and government budgets. It also offers its clients an online space for information, resources and help with running their businesses.
The practice mainly serves small businesses, alongside individuals who need tax and financial guidance. Its work is designed to save clients time on the administrative side of accounting, so that routine obligations are handled on schedule and the firm's advice is available when a decision needs to be made.
