Builder and Plumber Home Loans Sydney: How Lenders Assess Trade Income
By the Mortgagefy Team · Published · Last reviewed
Trade income is often variable: work comes in waves, you may be a sole trader or run a company, and tax deductions can make your taxable income look lower than what you really earn. This guide explains how lenders may assess that.

The real challenge
Lenders usually assess self-employed income from tax returns. If deductions reduce your taxable income, your borrowing capacity can look lower than your real earning power. Seasonal work and a new business add to that.
Some lenders accept alternative documents such as BAS statements or an accountant's letter, and some consider add-backs for certain business expenses. Policies vary by lender and by how long you have been trading.
How lenders may assess trade income
| Income type | What lenders commonly look at (varies) |
|---|---|
| Sole trader (ABN) | Tax returns, notices of assessment and BAS. Time in business matters. |
| Company director | Company and personal tax returns and financials. How salary, dividends and retained profit are treated varies. |
| Subcontractor or labour hire | Payment summaries or ABN income and your contract history. |
| Employee tradie | Payslips. Overtime and allowances may be partly included, depending on the lender. |
| New business (under two years) | Some lenders consider a shorter trading history with supporting documents, while others require two years. |
General information only. Requirements vary by lender and change over time. Confirm current requirements with your chosen provider.
Documents lenders may ask for
- Two years of tax returns and notices of assessment, or alternative documents where a lender allows them
- Recent BAS statements and business bank statements
- An accountant's letter confirming your income
- ABN registration details, proof of your deposit and identification
- A list of your debts and credit card limits
Ways to make your application clearer
- Keep your BAS and tax returns lodged on time
