You should hire a tax accountant once your finances become more than a single salary and a few basic deductions. The clearest triggers are starting a business or going out on your own, buying an investment property or shares, having a big one-off event like selling an asset or receiving an inheritance, earning income from several sources, or facing the ATO over a review or debt. In those situations an accountant usually saves more than they cost and keeps you out of trouble. If you earn a wage from one job with nothing unusual, you can still lodge it yourself. The rule of thumb is simple: the more moving parts, the sooner you need one.
Signs it is time to hire a tax accountant
As a quick checklist, it is worth speaking to a tax accountant if you:
have started, or are about to start, a business or sole trader work
have bought, or are about to buy, an investment property or shares
have sold, or plan to sell, an asset that could trigger capital gains tax
earn income from more than one source, or your income has changed a lot
are unsure which deductions you can claim, or think you are missing some
have received a letter, review, or debt notice from the ATO
simply do not have the time or confidence to get it right
Any one of these is a reasonable reason to get professional help. The sections below explain the most common ones.
You have started a business or gone sole trader
This is the most common trigger. The moment you start earning business income, your tax gets more complex: you have income to report, expenses and depreciation to claim, possibly GST and BAS, and decisions to make about structure. Getting this right from the start saves money and prevents mistakes that are expensive to unwind later. An accountant can also advise whether you should stay a sole trader or move to a company or trust as you grow, which is a decision with real tax consequences. Our business advisers help new businesses set this up properly from day one.
You have bought an investment property or shares
Investments add layers to your return. A rental property brings deductions, depreciation, and eventually capital gains tax when you sell. Shares and managed funds bring dividends, franking credits, distributions, and capital gains. These are exactly the areas where people either miss legitimate deductions or get the treatment wrong, and where an accountant’s knowledge pays for itself. If you have just bought your first investment, it is worth a conversation before your first tax time with it, not after.
You have a big one-off event
Some years are not like the others. Selling a property or business, receiving an inheritance, being made redundant, or realising a large capital gain can all change your tax position significantly, sometimes with planning opportunities that only exist before the event happens. A tax accountant can help you understand the consequences and, where possible, reduce the hit, for example by timing a sale or using an available concession. Waiting until the return is due often means the chance to plan has already gone.
Your situation has several moving parts
Even without a business or investments, complexity itself is a trigger. If you have two jobs, income from a side hustle, work across state or national borders, or a mix of employment and contracting, the return gets harder to get right and easier to get wrong. An accountant untangles it, makes sure nothing is missed or double counted, and gives you the confidence that the return is correct.
You are dealing with the ATO
If you have received a review, an audit, a debt notice, or a please explain letter from the ATO, that is the point to get professional help rather than face it alone. A registered tax agent can deal with the ATO on your behalf, respond correctly, and often resolve the matter faster and with far less stress than you would manage yourself. This is one of the clearest cases where an accountant is worth it.
When in the year should you engage one?
Most people think of an accountant only at tax time, but the more valuable timing is earlier. The tax you pay is largely decided before 30 June, so seeing an accountant during the year, especially before a big decision, lets them plan rather than just report. If you are starting a business, buying or selling an asset, or expecting an unusual year, speak to them beforehand. And if you simply want your annual return done, engaging a registered tax agent before 31 October also gives you a later lodgement deadline, often into the following May. Our tax planning checklist is a good way to prepare for either.
When you probably do not need one yet
To be fair, not everyone needs an accountant. If you earn a salary from one employer, have no investments, and claim only standard deductions, myTax will get you the same result for free, and an accountant adds little beyond convenience. A good accountant will tell you that honestly rather than take the fee. The value grows with complexity, so the right time to hire one is when your situation crosses from simple to something with real decisions and dollars attached.
How to choose one when you are ready
Once you have decided it is time, the next step is picking a good one. The key checks are that they are a registered tax agent, that they have experience with your kind of situation, and that they are upfront about pricing. Our guide on how to find a good tax accountant walks through exactly what to look for.
The short version
Hire a tax accountant when your finances gain moving parts: a business, investments, a big one-off event, several income sources, or contact from the ATO. Engage them ideally before the decision rather than after, because that is when they can plan and not just report. If your situation is genuinely simple, it is fine to wait and lodge yourself, and a good accountant will say so.
