What a BAS agent actually does
Only a BAS or tax agent registered with the Tax Practitioners Board may provide BAS services for a fee in Australia, under the Tax Agent Services Act 2009. Registration is checkable on the Tax Practitioners Board, public register (as at 14 October 2026). The service is the preparation and lodgment of activity statements, GST, PAYG withholding and PAYG instalments, from books that have been reconciled, plus the judgement calls that sit around them: GST on a mixed-use asset, an adjustment for a bad debt, a correction from an earlier period.
That last part is why the fee is not just a form-filling charge. A registered agent carries professional obligations and a safe-harbour position with the ATO that a chat tool or an unregistered helper does not.
How BAS agent fees are structured
| Model | What is included | Suits | Watch for |
|---|---|---|---|
| Per statement | Review of the quarter's figures, preparation, lodgment | A business that keeps its own books cleanly | Extra charges when the books need fixing first |
| Monthly bundle | Bookkeeping, BAS, often payroll, on a fixed fee | Owners who want one fee and one team | Scope creep in either direction; read the inclusions |
| Hourly | Time on whatever the agent is asked to do | One-off clean-ups and amendments | Open-ended; hard to budget |
Valont works on the monthly bundle model: bookkeeping, BAS and payroll as one function on a fixed monthly fee, month-to-month with no lock-in (Valont pricing). This page does not publish market price ranges, because none could be sourced to a reliable survey today; when one can, it will be added here with its source and date.
What drives the price
Four things move a BAS fee more than anything else. Transaction volume, because a quarter with 900 bank lines takes longer to review than one with 90. The state of the books, because an agent lodging from unreconciled accounts is doing bookkeeping first and BAS second. Whether payroll and superannuation are in scope, because from 1 July 2026 super is paid with each pay rather than quarterly (ATO, Payday Super for employers), which pulls payroll compliance into every month. And GST complexity: mixed supplies, imports, fuel tax credits and adjustments all take judgement.
What the alternative costs
The comparison most owners skip is what a late or wrong BAS costs. The ATO's failure-to-lodge penalty for a small entity is one penalty unit for each 28 days, or part of 28 days, a statement is overdue, up to five units (ATO, Failure to lodge on time penalty (last updated 22 Jun 2026)), and a penalty unit is $364 for infringements on or after 1 July 2026 (ATO, Penalty units (last updated 26 Jun 2026)). Interest on an unpaid amount runs separately. For FY2026-27 the standard quarterly dates are 28 October 2026, 28 February 2027 (a Sunday, so Monday 1 March), 28 April 2027 and 28 July 2027 (ATO, BAS agent lodgment program 2026-27); registered agents may have later dates under the ATO's lodgment program.
Questions to ask before you engage a BAS agent
Are you registered, and under what number? Will you lodge from books you reconcile, or from mine? What happens when a quarter needs a clean-up first, and is that priced separately? Who signs off, and when will I see the figures before lodgment? If payroll is included, how is Payday Super handled? An agent who answers those in writing is one you can budget around.
If this is the problem you are working on, Valont’s Finance hub runs bookkeeping and managed payroll as part of a connected back office, and the back-office cost calculator shows where to start.
