3 resources each dated and sourced
Every regulatory resource states the period it applies to, links the official sources behind its figures, and records when those sources were last verified.
ATO interest charges are no longer deductible: GIC and SIC from 1 July 2025
General interest charge and shortfall interest charge incurred on or after 1 July 2025 can no longer be deducted — enacted law, first biting in the 2025-26 returns now being prepared. What changed, the current quarterly rates, and what it means for payment plans and remission requests.

How to check that your tax agent is registered with the TPB
A plain-English walkthrough of the Tax Practitioners Board’s public register: how to search it, how to read an entry, what registration does and does not tell you, and why an unregistered preparer shifts risk onto you.

The mortgage broker best interests duty: what it actually requires
A technical guide to the statutory best interests duty for mortgage brokers — where it comes from, what ASIC’s RG 273 expects a broker to do, the conflict priority rule, the ban on conflicted remuneration, and the complaints path if you think the duty was not met.

What each resource answers
- How to check that your tax agent is registered with the TPB
The practical starting point: run the register check yourself, on any adviser, before handing over a tax file number. The resource walks the Tax Practitioners Board’s public register in sequence — where to find it, what to search on, and how to read what comes back, including registration status and any conditions attached. It also covers what a register entry cannot tell you, and what to do if your adviser does not appear at all. The check is free, and our own registration is published so the method can be tested on us first.
- The mortgage broker best interests duty: what it actually requires
Answers “what standard does the law hold my broker to?” — useful before, during and after any broker engagement. Inside: where the duty sits in the credit legislation, what it obliges a broker to do when recommending credit, the conflict-priority rule that travels with it, and the common misreadings that inflate the duty into promises the law never makes. This is a settled-law reference rather than a change log: the duty is enacted and in force, so the record is re-checked against ASIC guidance rather than tracked through parliamentary stages.
- ATO interest charges are no longer deductible: GIC and SIC from 1 July 2025
Read if you carry an ATO debt or payment plan: the economics of leaving it outstanding have quietly changed. This is a completed status track — the measure has moved from Budget announcement through bill to enacted law, and the record now documents the end state: which interest charges lost deductibility, the date the change took effect, and why a tax debt now costs more after tax than its headline rate suggests. Only ATO administrative guidance remains under watch, and the page records its last verification date.
About this collection
Who regulates the practitioners — and what changed
This collection covers the layer most clients never see: the rules that govern the practitioners themselves, and the regulatory changes that alter what good practice looks like. It exists for a simple reason — anyone can publish tax or lending content, and the difference between information and marketing is whether you can check the claims and the credentials behind them. These resources show you how.
It is written for two readers: clients — of any firm, not just this one — who want to confirm that the person handling their tax or their loan is registered and accountable, and readers trying to work out whether a change they have heard about is enacted law, a bill before Parliament, or merely an announcement. The discipline the whole Resource Centre applies — enacted versus announced, always with dates — matters most in this collection.
How to check that your tax agent is registered with the TPB walks through the Tax Practitioners Board register step by step — a check that takes minutes and that every taxpayer is entitled to make before handing over a tax file number. The mortgage broker best interests duty explains what the duty actually requires of a broker under the credit legislation, and — just as usefully — what it does not, so you can judge the service you receive against the standard the law sets.
The third strand tracks rule changes that shift behaviour. ATO interest charges are no longer deductible covers the removal of deductibility for the general interest charge and shortfall interest charge from 1 July 2025 — a change that quietly rewrites the economics of leaving a tax debt outstanding, and one that anyone on an ATO payment plan should understand.
A note on what qualifies as a regulatory update here. The label is reserved for status-tracking records: each attaches to a single measure or standard and follows it through its lifecycle — announcement, bill before Parliament, Act as passed, then regulator guidance — recording where on that path the measure currently sits. Some records, like the interest-charge change, have completed the journey; the practitioner-standards references describe settled law and simply hold their position. Review cadence follows the lifecycle rather than the calendar: a parliamentary stage or fresh guidance triggers a re-check, while stable records are re-verified on the scheduled cycle.
Resources here are verified against the regulators themselves — the TPB, ASIC and the ATO — and each page records when that check was last made; when a measure’s status moves from announced to enacted, the resource is updated and the change is dated rather than rewritten silently. Start with the TPB verification guide and run the check on your own adviser, whoever they are. The practice’s own registrations and licensing are published on the about page and in our Credit Guide, because a collection about verification should itself be verifiable.
