Short answer: not always. You can finance a vehicle through your ABN without being registered for GST. But GST registration often widens your options, especially for low-doc loans, and it affects what you can claim back on the vehicle.
Why lenders care about GST
- Evidence of trading. GST registration and BAS lodgements give lenders an independent view of your turnover.
- Low-doc programs. Many low-doc lenders require GST registration, often for a minimum period such as 12 to 24 months, because they rely on it instead of full financials.
- Loan size. Non-GST ABNs often face lower maximums on low-doc.
When GST registration is compulsory
- Generally, when your GST turnover is $75,000 a year or more
- Ride-sourcing (Uber, DiDi and similar) and taxi drivers must be registered before their first trip, regardless of turnover
What GST registration means for the vehicle
- Registered: you may be able to claim a GST credit on the purchase for business use. For cars, it's capped at one-eleventh of the car limit ($6,353 for 2026–27). Utes and vans designed to carry a tonne or more aren't capped by the car limit.
- Not registered: no GST credits, but you may still claim interest, depreciation and running costs for business use.
Not registered? Your options
- Full-doc business finance using tax returns
- Low-doc with lenders that accept non-GST ABNs, usually with a longer ABN history
- A consumer car loan, if you also have PAYG income or the car is mainly personal
More detail: low-doc car loans without GST registration.
Should you register just for finance?
Generally, no. Registering means charging GST and lodging BAS, which affects your pricing and admin. Make the decision with your accountant based on the whole business.
