Quote and bind the PI first
With the policy noting that TPB registration is applied for. The markets we use for tax practitioners have quoted on that basis, subject to their own terms.

BOOKKEEPER AND BAS AGENT INSURANCE
The TPB requires registered agents to maintain PI insurance that meets its requirements and to notify the Board of the cover, so most applicants arrange the policy up front rather than after approval. You pick the limit from a turnover estimate rather than a history, you name the insured to match how you will practise, and the certificate of currency goes into the application. New registrants we have placed have generally paid approximately $600 to $700 a year. That is a guide from past placements, not a quote.

THE SHORT ANSWER
How do I get professional indemnity insurance for a new BAS agent or tax agent registration in Australia?
Most applicants bind the PI policy first, with the insurer noting that TPB registration has been applied for, then use the certificate of currency in the application, because the TPB requires registered agents to hold compliant PI and to notify it of the cover. With no fee history, the limit is set from a reasonable estimate of the coming year's fees excluding GST: the TPB minimum is $250,000 up to $75,000 in fees and $500,000 from $75,001 to $500,000. Name the insured to match how you will practise, especially if the registration is in your own name and you trade through a company. New registrants Tank has placed paid approximately $600 to $700 a year. Guide only, not a quote.
Where an estimate sits near a tier boundary, it is worth pricing the higher tier before you bind. On our placements a $500,000 or $1,000,000 limit has often sat within a couple of hundred dollars of the floor, and on one submission it was cheaper.

It shows the insured name, limit, period and retroactive date.
And in whose name. If it lands in a director's personal name while you trade through a company, the policy may need a note or an endorsement so both are covered.
If you are applying as an individual but will operate through a company with another director or principal, say so up front. The insured entity, the registrant and the invoicing entity have to line up, or a claim can fall between them.
| New registrant | Estimated fees | TPB minimum | Outcome (approx.) |
|---|---|---|---|
| Accountant registering as a tax agent, sole practitioner, metropolitan NSW (quoted, not placed with us) | $50,000 | $250,000 | $500,000 quoted from $600; $250,000 at $1,100; $1,000,000 from $900 |
| Newly registered tax agent trading through a company, licence in director's name, South Australia | Around $75,000 | $250,000 | Placed at $650 for $500,000, below every $250,000 quote returned on that submission |
| New tax and accounting company, metropolitan NSW | Around $100,000 | $500,000 | Placed at $600 |
| First-year bookkeeper, no BAS registration yet | Under $20,000 | Not yet required | Quoted from $450 for $2,000,000; placed with public liability combined at $950 |
Two observations from that table: on these submissions the TPB minimum was not the cheapest option once a specialist market was included, and a $1,000,000 limit sat within a couple of hundred dollars of the floor. Where an estimate sits near a tier boundary, it is worth pricing the higher tier before you bind rather than endorsing mid-year.
Quote on the estimate and say the practice is pre-revenue.
If the insured entity or registrant is based outside Australia, the panel narrows sharply. On the one enquiry of this kind we handled, the markets we approached would not write it. Raise it before you apply so the placement question is answered first.
Any advice on financial products sits outside a bookkeeper or tax agent policy and requires separate licensing. If you will not give it, the policy should say so.
HR advice, payroll consulting and business advisory are quoted, but they change the occupation the underwriter rates and can trigger a referral.
