Second mortgage for the self-employed: when your income doesn't fit a bank's form

Self-employed people are often the strongest borrowers on paper that a bank never sees. The business makes money, the property has equity, but income arrives in lumps, tax returns run a year behind and deductions make the taxable figure look thin. A bank’s form wants payslips and two clean years. A private second mortgage asks different questions.

If you’re a sole trader, contractor, partner or new business owner, this page explains how a second mortgage works when your income doesn’t fit the usual mould.

Why do banks find self-employed borrowers difficult?

Banks build their decisions around serviceability: proving, from documents, that income comfortably covers repayments for years. business.gov.au’s own list of what lenders commonly request includes financial reports, cash flow statements and forecasts. For an employee, a payslip does the job. For the self-employed, the evidence is messier:

• Taxable income looks low because legitimate deductions reduce it.
• Income is lumpy, with big months and empty ones.
• Returns lag. A return for last financial year may not be lodged yet, and the year before that may not reflect today’s business.
• The business is new, with no full year of figures at all.

None of that means the business can’t repay a short-term loan. It means the bank’s yardstick doesn’t measure it well.

What does a private second mortgage look at instead?

Payslips or accountant’s income letter	The state of that existing loan: is it up to date?

We lend up to 80% of value on residential property and up to 70% on commercial, counting every existing loan on the title, and there’s no sworn valuation because we assess value ourselves. The equity calculator gives you a first idea of the room behind your current loan.

Which property can a self-employed borrower use?

Most self-employed borrowers use one of three:

• The family home. The second mortgage sits behind the home loan, which keeps running as normal. Our page on a second mortgage on your home for business covers the extra care that goes with using the home.
• An investment property. Often the cleanest option, because a sale is a natural exit. See our guide to a second mortgage on an investment property.
• Business premises. A workshop, shed or office you own can secure the loan too, within the commercial limit.

If the property is jointly owned, every registered owner signs. That might be a spouse or partner who isn’t in the business. Moneysmart’s guidance on guarantees is a useful read for anyone in that position: it encourages getting independent advice before signing and notes that a person backing a loan can be asked to repay it if the borrower can’t.

What if your tax returns or BAS are behind?

This is common and it’s not disqualifying. What matters is being upfront about it.

The ATO’s quarterly BAS dates for lodging and paying are 28 October, 28 February, 28 April and 28 July. If you’ve missed one or more, say which, and whether there’s a debt attached. If you owe the ATO, our page on a second mortgage with ATO debt covers how equity can clear it.

The one place late lodgements matter is the exit. If your plan is to refinance to a bank in a year, that bank will want lodgements up to date. Build the catch-up into the plan: the second mortgage solves today’s problem, and your accountant uses the breathing space to bring the books current.

What do self-employed borrowers use a second mortgage for?

It has to be a business purpose. Within that, the uses are as varied as the businesses:

• Tools, vehicles and equipment for a bigger contract. See equipment and machinery.
• Materials and wages for a job that pays on completion.
• A tax bill that landed at the same time as a slow quarter.
• Fit-out or premises costs for a move or expansion.
• Buying out a partner in a partnership that’s splitting up.
• Starting out, where there’s no trading history at all. See start-up businesses.

What it can’t be used for is personal spending, holidays or buying a home to live in.

Which exits work for the self-employed?

Interest can be capitalised for up to 6 months, so there are no repayments in that period, which suits income that arrives unevenly. The loan still needs a way to end:

1. A completed contract or invoice that pays the loan out.
2. The sale of a property or major asset.
3. A refinance, once returns are lodged and show the business clearly.
4. A tax refund or other expected receipt, with paperwork to show it’s coming.

Terms are open and there’s no early repayment penalty, so whichever arrives first can close the loan.

Illustrative example: a Ballarat sole-trader carpenter has been self-employed for three years. His last tax return showed modest income after deductions and this year’s isn’t lodged yet. He wins a $400k fit-out contract that needs $120k of materials and a second worker upfront. He and his partner own their home, worth about $800k, with $420k owing. Illustrative: at an 80% residential band, total lending could reach $640k, leaving $220k of room. A $120k second mortgage is approved on the equity and the signed contract, interest is capitalised, and the loan is repaid when the final progress payment lands five months later.

When should a self-employed borrower look elsewhere?

A second mortgage is a short-term tool. It’s probably not the answer if:

• the need is ongoing, such as topping up thin margins every month, rather than a defined job or bill;
• the home is the only asset and there’s no realistic exit apart from hoping trade improves;
• a bank top-up would arrive in time and the paperwork is already in order, because bank money costs less;
• the funds are really for household spending.

In those cases, a conversation with your accountant about cash flow, pricing or an ATO payment plan may serve you better.

What will you need to provide?

Less than a bank asks for, but enough to show the story:

• photo ID for every registered owner;
• the latest statement for the existing mortgage;
• your ABN and, if relevant, partnership or business name details;
• what the funds are for, such as a quote, invoice or contract;
• exit evidence, such as a contract, listing or accountant’s letter on refinance timing;
• a short note on any late lodgements or credit marks.
