Small Business Accountant in Adelaide | Tax Returns, BAS & Growth Advisory
From annual tax returns and BAS lodgement to cash flow planning and business advisory, our small business accountants help Adelaide's sole traders, companies, trusts, and partnerships stay compliant, reduce tax, and grow with confidence.
Is Your Business Tax Working For You or Against You?
Running a small business in Adelaide means wearing every hat at once. And when tax time arrives, most business owners simply want it done and dusted. The return gets lodged, the bill gets paid, and the opportunity to actually improve your tax position gets left for another year.
The businesses that grow fastest are not the ones working hardest. They are the ones with the right financial foundations: accurate books, proactive tax planning, a clear picture of cash flow, and an accountant who understands their numbers as well as they do.
At The Kalculators, we are the small business accountants Adelaide owners come to when they are ready to stop reacting and start planning. We handle your tax return, BAS, bookkeeping, and business advisory under one roof so your compliance and your growth strategy are always working together.
Business tax returns start from $120. Transparent pricing, discussed upfront and based on the complexity of your business, because you should always know what you are paying before we begin.
Business Tax Returns for Every Structure
Every business structure carries different tax obligations, different deduction opportunities, and different compliance requirements. Our team understands the specific rules that apply to your entity so your return is always accurate, complete, and optimised.
Sole Trader Tax Returns
As a sole trader, your personal and business income are one, making deductions and tax planning critical. We review your full income picture, claim every legitimate expense, and advise on structuring to reduce your tax liability year on year.
Company Tax Returns
Companies are taxed as separate legal entities, at either 25% or 30% depending on the base rate entity test. We prepare and lodge company returns with the correct rate applied and documented. See our company tax return page for the full service.
Partnership Tax Returns
We manage the full partnership lodgement cycle, ensure income is correctly distributed and reported across all partners, and advise on structuring to optimise every partner's tax position.
Family Trust Tax Returns
A family trust delivers real tax benefits only when distributions are planned strategically. We prepare your return, advise on distribution resolutions before 30 June, and ensure your trust keeps delivering the savings it was designed for.
SMSF Tax Returns & Administration
Our SMSF specialists prepare your annual return, manage trustee compliance, and keep your fund in good standing with the ATO, so your retirement savings stay protected, compliant, and growing.
Late & Multi-Year Business Tax Returns
Behind on business tax returns? We handle overdue lodgements confidentially, communicate directly with the ATO on your behalf, and apply for penalty remission where eligible to minimise the cost of late filing.
What Our Clients Say (Real Adelaide Stories)
Kylie A.
Adelaide, Australia
I've been running businesses for 21 years and have had several accountants in that time. These guys by far are the best I've dealt with. No mucking around, kept it simple, and answered all my questions. Highly recommended!
What is a BAS and when is it due?
A Business Activity Statement reports GST, PAYG withholding, PAYG instalments and other tax obligations to the ATO. Most small businesses lodge quarterly. Businesses with GST turnover of $20 million or more lodge monthly.
Quarterly due dates are 28 October, 28 February, 28 April and 28 July. Lodging through a registered BAS agent adds roughly four weeks to most quarters. The December quarter is the exception, where both self-lodgers and agents are due 28 February.
We prepare and lodge BAS as part of our BAS lodgement Adelaide service, reconciled against your accounts rather than estimated.

Office LocationsHow Much Does a Small Business Accountant Cost?
It is one of the most common questions small business owners ask, and one of the most important ones to get a clear answer on before you commit.
At The Kalculators, business tax returns start from $120. The final cost depends on your business structure, the complexity of your return, and the level of advisory support required. A straightforward sole trader return sits at the lower end. A company with multiple entities, trust distributions, and investment income sits higher.
What never changes is our commitment to transparency. We provide a clear quote before we begin, based on your specific situation, so you always know what you are paying and why. No hidden fees. No invoice surprises. Just honest pricing for professional work.
When you consider the deductions we identify, the planning we provide, and the compliance risk we remove, the cost of a professional small business accountant is one of the best investments your business makes each year.
