“How much does an accountant cost?” is one of the most common questions Australian small business owners ask — and one of the hardest to find a straight answer to online.

The reason is that “small business accountant fees” covers a huge range. A sole trader with one income source pays one number. A small company with payroll, BAS, inventory and a Virtual CFO scope pays a different number entirely. And the way the price is structured — hourly, fixed fee, or value-based — can mean two firms quoting the same dollar figure are actually proposing very different things.

This article gives a transparent look at what Australian small businesses should expect to pay an accountant in 2026, what drives the price up or down, how to tell whether you’re paying too much or too little, and the questions to ask before signing an engagement letter. It comes from our team at Trinity Accounting Practice — a Sydney-based registered tax agent practice with 22 years of experience pricing services for NSW small businesses.

The Three Ways Accountants Charge

Pricing structure matters as much as the headline number.

Hourly billing. The firm bills against time recorded on your file at a published hourly rate. Common range in 2026: $180–$450+ per hour depending on seniority. Honest, but the bill is unknown until the work is done — and complex jobs can blow out fast.
Fixed fee per engagement. A quoted amount for a specific deliverable (e.g., annual return + financial statements = $X). Predictable for both sides. Sometimes accompanied by a separate hourly rate for “out of scope” advice.
Fixed monthly subscription. A bundled monthly fee covering bookkeeping, BAS, year-end, plus a defined number of advisory calls. Increasingly the default for growing businesses because it smooths cash flow and reduces the “is this billable?” friction every time you have a quick question.
Value-based pricing. The fee is set based on the value delivered (e.g., a 1% scoping fee on a successful transaction, or a fixed advisory retainer). Common in Virtual CFO and M&A advisory work.

Realistic 2026 Fee Ranges in Australia

The ranges below are indicative market averages for small business clients in 2026 — not a Trinity quote. Your actual fee depends on the specifics.

Sole trader (one ABN, no employees)

Annual tax return only: $250–$600
Annual return + BAS lodgment (4 quarterly): $1,200–$2,400 per year
Full bookkeeping + BAS + annual: $300–$700 per month

Small company (1–5 employees, turnover under $2m)

Annual tax return + financial statements: $1,800–$4,500
+ Quarterly BAS lodgment: add $1,200–$3,000 per year
+ Monthly bookkeeping: add $400–$1,500 per month
+ Payroll (under 10 staff): add $150–$500 per month
Bundled fixed monthly (full compliance): $600–$1,800 per month all-in

Mid-sized SME (5–25 employees, turnover $2m–$10m)

Compliance (tax + BAS + bookkeeping + payroll): $2,000–$5,000 per month
+ Monthly management reporting: add $800–$2,000 per month
+ Virtual CFO with quarterly reviews: add $1,500–$4,000 per month

Other common services

SMSF annual compliance + audit coordination: $1,800–$3,500 per year (audit fee additional, paid to an independent SMSF auditor)
FBT return: $1,200–$3,500 depending on complexity
Business activity statement (single, ad-hoc): $220–$550
Tax planning meeting (90 minutes): $450–$1,200
Company setup (incorporation + ASIC + initial advisory): $1,400–$2,800
Trust setup (deed + ABN/TFN + advisory): $1,800–$3,500

What Drives the Price Up

The same business profile can attract very different fees depending on:

Bookkeeping quality. A clean Xero file with bank rules running smoothly is fast to work with. A file with months of un-reconciled transactions and a suspense balance is not. Many fee surprises come from clean-up work in the first three months of an engagement.
Multi-entity groups. Each company, trust, partnership and SMSF is a separate set of compliance. A “small business” with five entities is five engagements.
Inventory and stock. Adds bookkeeping complexity and year-end work.
Multi-currency / overseas income. Adds FX accounting and sometimes overseas advisory referrals.
Payroll size and award complexity. A 3-staff payroll is straightforward. A 25-staff retail payroll with shift loadings, leave loading and TFN declarations is materially more.
Lateness. Rushing prior-year returns for ATO catch-up always costs more than running on time.
Firm overhead. A CBD office costs more to operate than a suburban one. Virtual firms generally sit 15–30% below in-office firms for equivalent work.

What Drives the Price Down (Without Cutting Corners)

Clean, current bookkeeping. Worth more than any “discount” — a tidy file genuinely costs less to work with.
Bundling services. An accountant doing all your compliance will price differently than one doing only the annual return.
Locking in a fixed monthly fee. Both sides get predictability; the firm can plan capacity; you don’t get billed for every email.
Sending information once, complete. Eight rounds of “can you also send X” turns a 4-hour job into an 8-hour job.
Choosing a firm matched to your size. A Big 4 firm pricing model on a sole-trader business is rarely justifiable. Match the firm to the scale.

What “Too Cheap” Usually Means

If a quote feels surprisingly low, it usually means one of three things:

Scope is narrower than you think. “Annual tax return” might not include the financial statements your bank wants.
It’s the first year teaser. Year two prices revert to standard.
It’s a high-volume, low-touch firm. Lower price reflects less time on your file, less advisory, and a junior team member as your main contact.

None of these are wrong per se — just be clear which you’re buying.

The Five Questions to Ask Before Signing an Engagement

“Is this a fixed fee, an estimate, or an hourly arrangement?” Get it in writing.
“What’s specifically included and what’s specifically out of scope?” Most disputes come from ambiguity here.
“Who will I actually deal with day-to-day?” The partner who quoted may not be the person doing the work.
“How are ‘quick questions’ billed?” A fixed monthly arrangement should answer ‘no extra charge’ for routine queries.
“What’s your process when the fee will exceed the estimate?” A reputable firm tells you before doing the work, not after.

A Trinity insight from 22 years in practice

The most common pricing mistake we see new clients make isn’t paying too much — it’s choosing the cheapest quote without checking the scope. We’ve had clients arrive with three years of “$880 tax return” engagements that didn’t include the financial statements their bank needed for finance, didn’t include strategy review, and didn’t include any chasing of the ATO when issues arose. The headline fee was low. The actual value was very low. The cheapest accountant is rarely the one who saves you the most money.

What This Means for You

If you’re shopping accountants now: get fixed-fee quotes from at least two firms, with scope spelled out in writing. Compare on inclusions, not headline numbers.
If you’ve been with the same accountant for years and never reviewed the fee: a benchmark conversation every 2–3 years is healthy. The market and your business have both moved.
If your accountant only does the annual return: consider whether a small monthly retainer for advisory access would pay for itself in better decisions through the year.
