Bookkeeper, BAS agent, tax agent or DIY: who does what and how they charge
| Option | What they can do | Usual pricing model | Good for | Watch out for |
|---|---|---|---|---|
| Do it yourself with accounting software | Your own bookkeeping, invoicing, and lodging your own BAS and returns | Software subscription only | Simple sole traders with few transactions and time to learn | Errors in GST coding and missed deadlines; your time has a cost |
| Bookkeeper (not registered) | Data entry, reconciliations, invoicing and payroll processing under your direction | Hourly or monthly | Keeping records up to date between accountant visits | Cannot charge a fee for BAS services such as preparing or lodging your BAS |
| Registered BAS agent | Bookkeeping plus BAS services: GST, PAYG withholding and instalments, STP and super reporting | Hourly, per BAS or monthly package | Businesses with regular GST and payroll obligations | Cannot prepare income tax returns or give income tax advice |
| Registered tax agent (accountant) | Income tax returns, financial statements, tax advice, BAS and ATO representation | Fixed annual fee, hourly or package | Most companies, trusts and growing sole traders | Quotes often assume reconciled books; clean-up is billed extra |
Frequently asked questions
How much does an accountant cost for a small business in Australia?
There is no regulated or standard fee. The price depends on your structure (sole trader, company, trust), the number of entities and returns, whether BAS and payroll reporting are included, and above all the condition of your records. Get two or three written quotes with the same scope, and use the fee estimator to test whether the hours implied make sense.
Can a bookkeeper lodge my BAS?
Only if they are registered with the Tax Practitioners Board as a BAS agent or tax agent and charge you for it. An unregistered bookkeeper can do your data entry and reconciliations, but preparing and lodging a BAS for a fee is a BAS service that needs registration. Check the TPB register.
Are accountant fees tax deductible?
Generally yes: fees for preparing tax returns, managing your tax affairs and ongoing business accounting are deductible, usually in the year you incur them. Some costs, such as advice on setting up a new structure, may be capital. See the deductibility guide.
Will accounting software replace my accountant?
Software with bank feeds and rules can replace much of the data entry and reconciliation, and can cut the year-end fee if your books arrive clean. It does not replace tax judgement, year-end adjustments, structuring advice or representation with the ATO. See what automation actually replaces.
What changed for small business accounting on 1 July 2026?
The main change is Payday Super: employers now pay super with each pay cycle, generally reaching the fund within 7 days, and the Small Business Superannuation Clearing House has closed. ASIC fees were indexed and the $20,000 instant asset write-off threshold continues. Check the 2026 rules guide and the ATO for anything announced but not yet law.
How do I change accountants?
Appoint the new agent, nominate them through the ATO's online services, and ask the new firm to request your records and prior-year information from the old one. Export your software data and make sure you, not the old firm, own the subscription. See the switching guide.
Where can I complain about an accountant or tax agent?
Complaints about a registered tax or BAS agent's conduct go to the Tax Practitioners Board. If the person belongs to a professional body, that body also has a complaints process. Fee disputes and small business disputes can be raised with the ASBFEO or your state small business commissioner. See the complaints guide.
