Low-doc home loans for tradies and contractors: how they work and when they make sense

A low-doc home loan lets a self-employed borrower show income with documents such as BAS statements, business bank statements or an accountant's letter instead of two years of tax returns. They can suit tradies and contractors with a newer ABN or unlodged returns. They usually come with tighter deposit requirements and higher pricing, so many borrowers use one as a stepping stone and refinance later.

    If you're a sparky, chippie, plumber or machine operator working on your own ABN, the standard home loan checklist can feel like it was written for someone else. Most lenders want two years of personal and business tax returns. If you only started contracting last year, or your returns are still sitting with your accountant, that box stays empty. A low-doc loan is one way around it.

    What "low doc" actually means

    Low doc stands for low documentation. It doesn't mean no documentation, and it doesn't mean the lender skips checking your income. Under the responsible lending obligations in the National Credit Act, lenders and brokers must make reasonable inquiries about your financial situation and take reasonable steps to verify it. A low-doc loan simply lets you verify income with different evidence.

    Depending on the lender, that evidence could include:

    • Business activity statements (BAS), usually the most recent 6 to 12 months
    • Business bank statements showing regular deposits that line up with your declared income
    • An accountant's letter confirming your income, sometimes on a set form the lender supplies
    • A signed income declaration from you, backed by one of the above

    BAS statements matter here because they show turnover. A business must register for GST once its GST turnover reaches $75,000 or more, and a registered business lodges BAS. If you're under the threshold and not registered, your bank statements and an accountant's letter will do more of the work.

    Who it can suit

    Low-doc lending tends to fit a few common situations we see around Mackay and the Bowen Basin:

    • You've held your ABN for a year or so and your first full tax return isn't lodged yet
    • Your business has grown fast and last year's return no longer reflects what you earn
    • You moved from a wage job to contracting on the same site and your income is steady, just structured differently
    • Your returns are behind and you want to buy before they're caught up

    Time on your ABN still counts. Some lenders look for at least 12 months of ABN registration, others for two years, and a few may consider less if you worked in the same trade as an employee beforehand. It depends on the lender and your circumstances.

    The trade-offs

    Lenders see low-doc loans as higher risk because the income evidence is lighter. You'll usually feel that in three places:

    1. Deposit. Many lenders cap low-doc loans at a lower loan-to-value ratio than full-doc loans, so you may need a bigger deposit.
    2. Pricing. Interest rates and fees on low-doc products are generally higher than on standard home loans.
    3. Mortgage insurance. Where a lender allows a higher loan-to-value ratio, lenders mortgage insurance may apply, and it can cost more on a low-doc loan.

    Because of that, it pays to check whether you really need low doc. Plenty of tradies assume they don't fit a standard loan when they do. If you have one year of returns, some lenders will assess on a single year. If you contract to one main client on a regular roster, some lenders may assess you much like a wage earner using your contract and recent invoices. Those options are worth ruling in or out first.

    Contractors on a mine site

    A lot of Bowen Basin contractors run an ABN but work like employees: one client, a fixed roster, regular invoices. That pattern can help. A steady run of invoices and matching deposits tells a lender more than a single lump of annual income does. Keep your invoicing regular and your business account separate from your personal spending. Both make the assessment easier whether you go low doc or full doc. Our mining and FIFO home loans page covers roster income in more detail.

    Getting your paperwork ready

    Before you talk to a lender, pull together:

    • Your ABN and GST registration details
    • BAS statements for the last 12 months, if you lodge them
    • Six to 12 months of business bank statements
    • Your accountant's contact details, so the lender's form can be completed quickly
    • Details of any tax debt and any payment plan with the ATO
    • Your deposit savings history and personal bank statements

    Be upfront about tax debts and late lodgements. Lenders find them anyway, and an explained issue is far easier to place than a surprise.

    Plan your exit from low doc

    A low-doc loan works well as a bridge. Once your tax returns are lodged and show the income, you may be able to move to a full-doc loan with sharper pricing. Put a reminder in for when your next return is assessed, and have a look at our refinance page when you get there. Any refinance depends on your circumstances at the time, including property value and income.

    Your accountant can advise on how your business structure and tax position affect what shows up on paper. We then look for lenders whose policy fits those figures. More on that on our self-employed home loans page.

    For most home loans there's no broker fee; any fee is disclosed upfront in our Credit Guide.

    Common questions

    Can I get a home loan with only one year on my ABN?

    Some lenders may consider it, particularly if you worked in the same trade before going out on your own. Others want two years. It depends on the lender and your circumstances.

    Is a low-doc loan more expensive?

    Usually, yes. Low-doc products generally carry higher pricing and may need a larger deposit than a standard home loan.

    Do I need to be registered for GST to get a low-doc loan?

    Not always. BAS statements help, but if you're under the $75,000 GST threshold, some lenders may accept business bank statements and an accountant's letter instead.

    Can I switch to a standard loan later?

    You may be able to refinance to a full-doc loan once your tax returns are lodged and show your income. It depends on your circumstances and the lender at the time.
