Accountant Fees for Small Business: What Drives the Cost

Darren Trew, CA 7 September 2026 9 min read

Every small business owner wants the same thing from this question: a number. What should I be paying an accountant?

The honest answer is that the number depends on things a stranger cannot see from the outside, and most of them are about your business rather than about the accountant. What is useful is understanding what moves that number, because several of those things are within your control and one of them can halve a bill.

Why Nobody Publishes a Price List

You can find quoted ranges for accounting work online. Treat them carefully, because the spread within any one of them is usually so wide as to be useless for budgeting, and the same service description covers very different amounts of work.

"Annual tax return" for a sole trader with one income stream and tidy books is a couple of hours. The same three words for a company with staff, inventory, a trust distribution and a year of uncategorised transactions is a different job entirely. Any range broad enough to cover both tells you almost nothing about which end you sit at.

What you should expect instead is a quote, given in writing, after someone has looked at your actual situation. If a firm cannot tell you what a piece of work will cost before they start it, that is worth knowing early.

The right question is not "what do accountants charge?" but "what will this cost for my business, and what changes it?" Any accountant worth engaging can answer the second one specifically.

The Three Ways You Get Billed

Almost every arrangement is one of three shapes, and the shape matters as much as the rate.

Hourly

How it works
Time recorded against your file and invoiced, usually monthly.
Good for
Unpredictable work with no clear scope: an ATO query, a one-off problem.
Watch for
No cost certainty. A job that uncovers something takes longer, and you carry that risk.

Fixed fee

How it works
An agreed price for defined work, set before anything starts.
Good for
Jobs with a clear beginning and end: an annual return, a company setup.
Watch for
What sits outside the scope. That is where the extra invoices come from.

Monthly retainer

How it works
A recurring fee covering an agreed bundle of ongoing work.
Good for
Continuing needs: bookkeeping, activity statements, payroll, regular advice.
Watch for
Scope creep in both directions. Review it yearly against what you actually used.

There is a quieter benefit to fixed and retainer arrangements that owners consistently underrate. When the meter is running, people stop ringing their accountant. They sit on a question for three months, make the decision without advice, and the advice would have been worth more than the call. Predictable pricing removes that hesitation, and that is usually where the value is.

Trew North works on flat rates for this reason. Not because it is cheaper in every case, but because it means clients ask.

What Actually Drives the Number

Four things, in roughly descending order of impact.

Your structure

A sole trader has one return and modest obligations. A partnership adds a return of its own on top of each partner's. A company brings ASIC obligations, director duties and formal financial statements. A trust adds annual resolutions and its own distribution rules, with real consequences for getting them late or wrong.

Each step up is more work every year, permanently. It is worth understanding that before you restructure, because the compliance cost is part of the trade. Our guide to business structures covers what each one actually asks of you.

Volume

A consultant issuing five invoices a month and a retailer processing several hundred transactions a day need different amounts of work, regardless of turnover. Volume is what drives bookkeeping effort, and bookkeeping is usually the largest recurring line.

The state of your records

The single biggest swing factor, and the one nobody quotes for accurately, because it is only visible once the work starts. More on this below, because it is also the one you control.

What you are actually asking for

Compliance, which is lodging what must be lodged, is the floor. Bookkeeping is ongoing work at a different rate. Advisory sits above both because it needs someone senior thinking about your business rather than processing it. Specialist work such as SMSF administration or a business valuation is priced accordingly.

Bookkeeping and accounting are genuinely different jobs charged at genuinely different rates, and paying the second rate for the first kind of work is the most common way to overspend. We set out the difference in bookkeeping versus accounting.

The Part You Control

An accountant's time is the entire product. Anything that consumes it without producing anything shows up on your invoice, and disorganised records consume enormous amounts of it.

The gap between a well-kept file and a poorly kept one is not marginal. The same business, same structure, same turnover, can cost substantially more to look after simply because someone has to reconstruct the year before they can begin on it. That reconstruction is billed at professional rates and produces nothing you did not already have.

Four habits do most of the work:

  • Separate the accounts. A dedicated business bank account and card, with nothing personal running through them. Untangling mixed accounts is slow, and it has to happen before anything else can.
  • Reconcile weekly. Twenty minutes a week beats a day in July, and errors get caught while you can still remember what the transaction was.
  • Capture receipts as you go. Photograph them when they are in your hand. A receipt you cannot find is a deduction you cannot claim, which costs more than the bookkeeping did.
  • Send everything at once. Bank statements, loan documents, asset purchases, in one go rather than a fortnight of follow-ups. Chasing is billable time and it also delays your lodgement.

Cloud software does most of this for you now, provided you actually use it. Our guide to the best accounting software for small business in Australia covers the options, and bookkeeping habits covers the routine.

Clean books are the cheapest thing you can buy. Every hour your accountant spends sorting out what happened is an hour not spent on what to do about it, and you pay the same rate for both.

What to Ask Before You Engage

Comparing accountants on price alone is difficult, because you are rarely comparing the same scope. These questions make the comparison real.

On price

  • Will I get a written quote or engagement letter before work starts?
  • What is specifically included, and what is out of scope and billed separately?
  • How and when am I invoiced?
  • What happens if the job turns out to be bigger than expected? Do you come back to me first?

On the work

  • What are you registered for? A registered tax agent can lodge income tax returns, a BAS agent can lodge activity statements, and the registration is checkable on the Tax Practitioners Board register.
  • Who actually does my work, and who do I speak to?
  • Do you have clients in my industry and at my stage?
  • Which software do you work in, and does it match mine?

On the relationship

  • Am I charged for quick questions by phone or email?
  • What is a normal turnaround for a query?
  • Will you tell me about changes that affect me, or do I need to ask?

That first question in the last group matters more than it looks. It determines whether you have an adviser or a lodgement service.

Cheaper Is Not Always Cheaper

Fees are a real cost and worth managing. They are also small next to the things a good accountant changes: the structure you trade through, the deductions you actually claim, the tax you pay on a sale, the deadline you do not miss.

A cheap return that misses a concession costs more than an expensive one that finds it. A missed lodgement brings penalties and interest that dwarf the saving. The point is not that dearer is better, because it often is not. The point is that the fee and the value are different numbers, and only one of them appears on the invoice.

The sensible test is whether you are getting something back beyond compliance: a call before 30 June rather than after it, a heads up when a threshold is about to catch you, an answer when you are deciding whether you can afford to hire. If the only contact you have all year is an invoice and a return to sign, you are paying for the cheapest part of what an accountant does.

Frequently Asked Questions

Are accounting fees tax deductible?

Yes. Fees for managing your tax affairs and for work related to earning your income are deductible, and that includes the cost of preparing and lodging returns. Keep the invoices.

Should I pay for bookkeeping and accounting separately?

You need both functions, but not necessarily two providers. A single firm doing both removes the handover, which is where errors and delays tend to appear. Two providers can work well when the bookkeeping is in house. What does not work is paying accounting rates for bookkeeping tasks.

Is a cheaper accountant a false economy?

Not automatically. A simple business with clean records genuinely does not need much, and paying for advisory you never use is its own waste. The false economy is buying compliance only, then finding out at the point of a sale, an audit or a restructure that nobody was thinking about your position.

What should I expect for the money?

At minimum: work lodged on time and correctly, a written scope, and an invoice with no surprises in it. Beyond that, contact before decisions rather than after them.

Can I change accountants mid year?

Yes, and it is more routine than people expect. Your records are yours, and the incoming accountant handles the transfer with the outgoing one through an ethical clearance letter. The best time is right after a lodgement, when the file is in a natural resting state.

Why is a quote sometimes lower than the final invoice?

Usually because the work found something the quote could not have known about, most often in the records. A firm that quotes properly will come back to you when that happens rather than presenting it at the end. Ask in advance what their practice is.


What an accountant costs is a fair question, and the useful version of it is specific to your business. Structure, volume, the state of your books, and what you actually want done between them decide almost all of it.
