The catch-22 of self-employment: you minimise your taxable income to cut the tax bill, then cannot show enough income to get a home loan. Lenders want two years of tax returns, the gross-to-net gap works against you, and "mortgage-ready" is a 1-2 year project, not a six-week one. Here is how it works and how to prepare.
What lenders want — income evidence
The standard full-doc self-employed assessment:
- two years of personal tax returns and ATO Notices of Assessment (your taxable income);
- two years of business, company or trust returns and financials if you trade through an entity;
- ABN history, BAS and business bank statements (3-12 months).
Lenders usually average the last two years (or use the lower year if income fell), and may "add back" non-cash deductions like depreciation for a truer serviceability picture. One-year or "low-doc / alt-doc" deals exist through specialist lenders and brokers (12 months' BAS plus bank statements and an accountant's declaration, sometimes a shorter ABN) — but at higher rates and a larger deposit.
The construction subbie complications
Four things work against a tradie:
- The gross-to-net gap — you invoice $220k but show $90k taxable after tools, vehicle, fuel and insurances, and the bank can only lend against the $90k.
- Lumpy, project-based income that makes lenders nervous without a consistent annual pattern.
- Equipment finance on the balance sheet (utes, excavators) increases liabilities and reduces borrowing power.
- Trading through a company or trust — money in your Pty Ltd or trust does not count as personal income unless it is clearly distributed (wages, directors' fees, dividends, distributions).
Broker tactics that help: choosing a lender on policy not just rate (ones that add back non-cash and accept contracting margins), cleaning up the entity structure so company profits visibly flow to you, documenting which equipment debt is paid out at settlement, and using contractor-friendly rules (some lenders treat a long-term contractor — 12-24 months, often ~48 weeks, with the same head contractor — more like a PAYG employee).
Deposit, LVR and pricing
- Full-doc with strong financials can reach 90-95% LVR with LMI, though 80% is much easier for variable income.
- Low-doc / alt-doc typically sits at 60-80% LVR with a 20%+ deposit.
- The sweet spot is a 20% deposit (80% LVR), where mainstream lenders extend near-PAYG rates to a clean self-employed file.
Like-for-like (same income strength, LVR and credit), pricing is often similar to PAYG — the difference is more about how hard approval is than a headline self-employed loading.
Government schemes — the Home Guarantee Scheme
The Home Guarantee Scheme (Housing Australia) includes the self-employed (income-tested on your Notice of Assessment):
- First Home Guarantee — as little as a 5% deposit, no LMI (the government guarantees part of the loan). (The scheme was significantly expanded around 1 October 2025 — the income and property-price caps changed, so confirm the current caps.)
- Regional First Home Buyer Guarantee — similar, for regional buyers.
- Family Home Guarantee — as little as a 2% deposit for eligible single parents.
A strong self-employed file benefits fully from the low-deposit feature — but the guarantee cannot fix a weak set of returns; you still meet the lender's self-employed credit criteria.
The 12-24 month prep
"Mortgage-ready" for a tradie is a 1-2 financial year project, not six weeks:
- Plan tax with the loan in mind — work with your accountant before 30 June to balance tax minimisation against showing enough taxable income for the target loan over the relevant years.
- Lodge returns early — the last two years lodged with NOAs issued, and no outstanding years, ATO payment plans or disputes when you apply.
- Separate business and personal — a dedicated account and a regular wage or drawings.
- Tidy the structure — show company or trust profits flowing to you via wages and dividends.
- Manage debt and bank conduct — pay down high-interest consumer debt, clear or document equipment finance, and avoid overdraft dishonours, BNPL and gambling markers in the 6-12 months before applying.
Common mistakes
- Maximising deductions for tax then being unable to show income for the loan.
- Returns lodged late, so the latest assessed year is not available.
- Mixed personal and business accounts that hide the true household cash flow.
- Applying six weeks out instead of preparing over 1-2 financial years.
