ABN & Business Credit Guide Australia | Loan Eligibility

By AusTaxTools Editorial Team · March 17, 2026

Short answer

Getting a business loan in Australia starts with your ABN. Most lenders want to see at least 2 years of trading history backed by BAS statements or tax returns. Your business structure, GST registration status, industry risk profile, and personal credit history all factor into eligibility and the rate you are offered. Newer businesses have options, but they come at a premium.

ABN age matters

Lenders use ABN age as a proxy for business viability. Under 1 year is considered high risk by most banks. At 2+ years with consistent BAS lodgements, you unlock mainstream rates. GST registration signals revenue above $75k and adds credibility.

Structure impacts access

Sole traders are assessed on personal financials, which limits separation between business and personal risk. Companies (Pty Ltd) can build a separate credit profile but need directors' guarantees for most small business loans. Trusts add complexity to applications.

Credit history

For small business loans, lenders check both the business credit file and the directors' personal credit. Defaults, late payments, or too many recent applications can trigger declines. Check your Equifax business and personal reports before applying.

Common mistakes

Applying to multiple lenders in quick succession — each credit inquiry can lower your score and signal desperation to subsequent lenders.
Not having BAS statements up to date — lenders use these to verify revenue and GST compliance. Overdue BAS is a red flag.
Assuming a brand-new ABN means no options — some lenders offer startup business loans, but you need a strong personal credit profile and often security.
Mixing personal and business finances extensively, making it harder for lenders to assess true business cash flow.

Frequently asked questions

How old does my ABN need to be to get a business loan?

Most mainstream lenders require an ABN that has been active for at least 2 years with matching tax returns or BAS statements. Some specialist lenders accept 1 year, and a handful offer loans to businesses trading for 6 months — but at significantly higher rates.

Does being a sole trader vs a company affect my loan options?

Yes. Companies with an ACN can access a wider range of business lending products. Sole traders are assessed partly on personal income and credit, which can limit options but also simplifies the application. Trusts and partnerships have their own documentation requirements.

Can I get a business loan with bad credit?

Some non-bank lenders specialise in adverse credit business lending, but rates are substantially higher — often 15% to 25%. Improving your credit score before applying, offering security, or using invoice finance as an alternative can provide better outcomes.
