TPB Advertising Rules for Accountants: What Registered Tax Agents Can (and Can't) Claim in Marketing

26 August 2026·5 min read

Quick answer: Registered tax and BAS agents must not advertise in a false, misleading or deceptive way, and must accurately represent their registration and qualifications — a well-established principle under the TPB Code of Professional Conduct. In practice, that rules out guaranteed-refund claims, vague "registered agent" language that doesn't specify what you're actually registered for, and implying services you're not qualified to provide. Below is a self-check list to run before you publish any ad or post, three worked examples, and the mistakes that quietly cross the line. ✨

Marketing an accounting practice is a strange balancing act — you need to sound confident enough to win the client, without ever promising an outcome you can't control. Most firms don't set out to mislead anyone; they just reach for the same punchy phrases everyone else uses, and some of those phrases don't hold up. Here's how to market with genuine confidence and stay clearly on the right side of the line. 💖

What most accounting firms get wrong

"Guaranteed maximum refund" style claims — no agent can guarantee a specific tax outcome for a client they haven't assessed.
Vague "registered agent" language that doesn't say registered with whom, or for what — tax agent, BAS agent and bookkeeper are not interchangeable.
Letting old badges and claims linger on a website or ad after a registration has lapsed, changed, or was never actually held by every team member listed.
Testimonials that promise a repeatable outcome — "they got me $4,000 back!" implies every client gets the same result.
Implying a service you're not registered to provide — a BAS-agent-only business hinting at income tax return services is the most common version of this.

The marketing claims self-check list

Run every ad, post or website line through this before it goes live:

1. Am I claiming a specific outcome (a refund amount, a guaranteed saving)? If yes, remove or generalise it.
2. Am I accurately describing my registration — tax agent, BAS agent, or neither — rather than a blanket "registered accountant"?
3. Does this imply a service I'm not currently registered or qualified to provide?
4. Would a reasonable person reading this expect a guarantee I can't actually give?
5. Is my TPB registration status current, and correctly described for every person named or pictured?
6. Are testimonials general ("made tax time painless") rather than promising a replicable financial outcome?

Three worked examples

Same principle, three different practice structures. 📈

Sole-practitioner accountant: a social ad reading "I'll get you the biggest refund possible, guaranteed" gets reworded to "I'll make sure you're claiming everything you're legitimately entitled to — no guesswork, no missed deductions." Same confidence, no promised outcome.

Small accounting firm: a website banner claiming "award-winning" needs to point to a real, verifiable award — not a vague nod to unspecified recognition. If it's genuine, name the award; if it's not something you can point to, drop the claim rather than let it imply more than it means.

BAS-agent-only bookkeeping business: marketing copy saying "we handle all your tax" gets tightened to "we handle your BAS lodgement, payroll and bookkeeping — and work alongside your tax agent for income tax returns." It's honest about scope and still reads as capable, not limited.

Why this actually matters (the general principle)

The TPB Code of Professional Conduct requires registered agents to act honestly and with integrity, and specifically not to advertise in a way that's false, misleading or deceptive — including about their registration status, qualifications and the services they're entitled to provide. It's a broad, well-established standard rather than a list of banned words, which means the test is less "did I use a forbidden phrase" and more "would this reasonably mislead someone about what I can promise or provide." That's a useful lens for any new ad, not just the obvious ones.

💡 Heads up: "no guaranteed refund" claims are one of the most consistently flagged issues across the industry — if a competitor is running that line, it's not proof it's fine, it's a sign their marketing hasn't been checked. The same caution applies to testimonials that mention a specific dollar figure; keep those general, or add a plain "individual results vary" note.

Mistakes to avoid

Copying a competitor's ad language without checking whether it actually holds up.
Forgetting to update marketing when a registration lapses, a team member leaves, or your service scope changes.
Using "tax agent" and "accountant" interchangeably when they're not the same registration.
Publishing testimonials with specific outcomes attached, without any general disclaimer.
Assuming social media posts are lower-stakes than the website — the same standard applies everywhere you advertise.

Please note: this is general information, not legal or professional advice — always check current guidance from the Tax Practitioners Board (TPB) and the TPB Code of Professional Conduct for your specific registration and circumstances before publishing marketing claims.

Frequently asked questions

Can I say "registered tax agent" in my ads?

Yes, if you genuinely hold current registration — it's a legitimate and useful trust signal. The honest catch is that it needs to stay current and accurate for exactly who it describes; if a named team member's registration lapses or changes, update the marketing at the same time, not months later.

Can I promise a specific refund amount?

No — steer well clear of any guaranteed or specific-figure refund claim, since no agent can promise an outcome before assessing a client's actual situation. "We'll make sure you claim everything you're entitled to" does the confidence job without the guarantee.

Can a BAS agent advertise tax return services?

Only if they're genuinely also a registered tax agent for that purpose — BAS agent and tax agent are separate registrations with separate scopes. Advertising income tax return services without that registration is exactly the kind of misleading claim the Code is aimed at.

What if a client's testimonial mentions a refund figure?

Here's the honest trade-off: a specific, glowing figure makes a great testimonial but risks reading as an implied guarantee to anyone else who sees it. The safer approach is to keep published testimonials general, or pair a specific one with a plain note that individual results vary.
