Can I Get a Home Loan With Just an ABN?

A lot of self-employed borrowers ask the same question:

Can I get a home loan with just an ABN?

The honest answer is: sometimes, but usually not with the ABN alone.

An ABN helps show that you are operating a business. But the lender still wants to know whether the business is making money, how long it has been operating, whether the income is consistent, and whether the loan is affordable.

ABN-only vs ABN plus income evidence

An ABN proves registration. It does not prove serviceability.

The lender may still ask for:

• Tax returns.
• Notices of assessment.
• BAS.
• Accountant letter.
• Business bank statements.
• Profit and loss statement.
• Invoices and contracts.
• Evidence of recurring work.
• Details of debts and tax liabilities.

The ABN tells the lender the business exists. The income evidence tells the lender whether the business can support a mortgage.

ABN and GST registration

GST registration can matter because it helps the lender understand business scale and reporting history.

Business.gov.au says businesses must register for GST when GST turnover is $75,000 or more, and that registration is optional below the threshold unless another rule applies. It also says businesses should register if they expect turnover to reach the threshold in the first year and must register within 21 days after becoming aware they will go over it.

The Australian Business Register also states that GST registration is required when business GST turnover is $75,000 or more, and that taxi or limousine passenger travel providers must register regardless of turnover.

This does not mean every borrower under $75,000 must be GST registered. It means the story needs to make sense.

If the borrower claims strong turnover but has no GST registration, the lender may ask questions.

Do I need an ABN if I earn less than $75,000?

This question mixes two different things.

An ABN and GST registration are not the same.

You may have an ABN without GST registration if your turnover is below the GST threshold and no other rule requires GST registration. For lending, the bigger issue is not only whether GST is registered. The bigger issue is whether income can be proven.

How long do you need an ABN before getting a home loan?

This depends on lender policy.

Some lenders prefer two years of ABN history and two years of financials. Some may consider one year. Some specialist or alt-doc lenders may consider shorter trading history.

Westpac says low-doc home loan requirements can include a registered business name, ABN, and in most cases an ABN held for at least two years, plus BAS for the last 12 months and GST registration history. Pepper Money advertises self-employed options that may consider six months of ABN and GST registration, subject to full assessment.

That is why lender choice matters. The same borrower can be a poor fit for one lender and a workable fit for another.

Sole trader vs company vs trust

The structure changes the documents.

This is why an ABN loan cannot be treated like a basic payslip application.

Can I use BAS instead of tax returns?

Sometimes.

NAB lists BAS as a document that may be used if tax returns are not available. Pepper Money lists lodged BAS as one possible alt-doc evidence item when combined with GST and ABN evidence and a declaration of financial position.

But BAS shows turnover. It does not automatically show net profit.

A business can have high turnover and low profit. The lender still needs to understand expenses, margins, debts, and real repayment capacity.

Common mistakes ABN borrowers make

Thinking an ABN is enough

An ABN supports the story. It is not the full story.

Waiting too late to prepare financials

If the latest year is strong, speak to your accountant early so financials are ready when needed.

Not registering for GST when required

If turnover is above the threshold, GST registration and BAS history need to be handled properly.

Mixing personal and business banking

Clean statements make the application easier to explain.

Going to the wrong lender

Some lenders are far better than others for self-employed and ABN borrowers.

What to do next

1. Confirm your ABN start date and GST status.
2. Check whether you have current tax returns and notices of assessment.
3. Gather BAS and business bank statements if tax returns are not ready.
4. Check business and personal debts.
5. Decide whether the file is full-doc, low-doc, or alt-doc.
6. Use start enquiry if you want NewGen to check lender fit.

Final word

You can sometimes get a home loan with an ABN, but the ABN is not the approval.

The approval depends on income evidence, trading history, deposit, credit profile, debts, and lender policy.
