How Lenders Assess Your Income for a Home Loan
Lenders assess your income by examining its consistency, verifiability, and likelihood of continuing. Permanent employees with a base salary typically receive the most straightforward assessment, while variable income, overtime, and self-employment require additional documentation to confirm stability.
Consider a buyer working full-time in Brisbane's CBD on a base salary of $95,000 with regular quarterly bonuses averaging $8,000 per year. The lender will include the full base salary immediately but may only recognise 80% of the bonus income after reviewing the last two years of payment summaries and recent payslips. That approach reduces the assessed income from $103,000 to around $101,400, which directly affects borrowing capacity and the loan amount approved.
Lenders apply different policies depending on how income is earned. Base salary is assessed at 100% if employment has been ongoing for at least three months. Overtime and allowances are typically averaged over the most recent 12 to 24 months, and lenders may apply a discount of 20% to account for variability. Commission income follows a similar pattern, with most lenders requiring at least two years of evidence and applying a discount unless the income has been consistent or increasing. Rental income from investment properties is assessed after deducting expected vacancy rates, property management fees, and other costs, usually at around 80% of the gross figure.
Self-Employed and Contract Workers: What You Need to Prove
Self-employed applicants and contractors need to provide tax returns and financial statements covering at least two full financial years. Most lenders assess the taxable income shown on your ATO Notice of Assessment, adding back certain non-cash deductions like depreciation depending on the lender's policy.
In our experience, self-employed buyers in Brisbane often underestimate how their declared income affects what they can borrow. A buyer operating a profitable small business in Fortitude Valley might show a taxable income of $78,000 after legitimate deductions, even though the business generates significantly more. Lenders typically work from that $78,000 figure unless you apply through a lender that offers low-doc or alternative income verification products, which generally come with a higher interest rate and may require a larger deposit.
Contractors on Australian Business Number (ABN) arrangements are treated similarly to self-employed applicants if they have been contracting for more than two years. Contractors with less than two years of history but more than 12 months may still be assessed, though fewer lenders will accept the application and the terms may be less favourable. Pay-as-you-go (PAYG) contractors who receive regular pay through a recruitment agency and have tax withheld at source are often assessed in the same way as permanent employees, provided the contract has been ongoing or regularly renewed.

How Employment Type Affects Your Interest Rate and Loan Terms
Employment type influences not just whether you are approved, but also the interest rate, the loan-to-value ratio you can access, and whether the lender will waive certain fees. Applicants in permanent employment typically access the lowest advertised rates and can borrow at higher LVRs without additional scrutiny.
Casual employees, contract workers, and those in probationary periods are often subject to rate loadings or stricter deposit requirements. Some lenders will not lend to casual employees who have been with their current employer for less than six months, while others will assess casual income only after 12 months of continuous employment in the same role or industry. A casual worker in Brisbane's hospitality sector may have two years of consistent rostered hours and income, but if the employment contract is classified as casual, several lenders will either decline the application or require a 15% to 20% deposit rather than the standard 10%.
Probationary employment is treated differently depending on the lender. Some lenders will assess a borrower who is within their probation period if they can provide a signed employment contract showing permanent employment will commence after the probation ends. Other lenders require the probation period to be completed before they will assess the application. Applicants who change jobs frequently or move between industries may also face additional questions, as lenders assess the likelihood that income will continue.
Strengthening Your Application Before You Apply
The most effective preparation involves aligning your employment and financial documentation before a lender reviews your file. Obtain your most recent payslips, ATO Notice of Assessment, employment contract, and any records of additional income such as rental statements or trust distributions. Check that your employer can provide a letter confirming your position, salary, and employment status if the lender requests one.
If you receive variable income such as overtime, bonuses, or commissions, gather evidence showing that income has been consistent over at least 12 months. A single large bonus paid in one year but not repeated will not usually be included in your assessed income. Applicants in casual or contract roles should compile timesheets, contracts, and payment summaries that demonstrate regular hours and income continuity.
Reducing liabilities before you apply also improves your position. Lenders assess your debts against your income using a debt-to-income ratio and serviceability calculation. Paying down credit card balances, closing unused credit accounts, and clearing personal loans or buy-now-pay-later arrangements will increase the amount you can borrow. Even if you do not carry a balance on a credit card, the lender includes the full credit limit in their serviceability assessment, so reducing or closing those accounts has a measurable impact.
Documentation Requirements for Different Income Types
Lenders require different supporting documents depending on how you earn income. Permanent employees typically provide two recent payslips, an employment letter, and the most recent ATO Notice of Assessment. If you have been in your current role for less than six months, the lender may also request a signed employment contract and evidence of previous employment to confirm work history.
Self-employed applicants provide two years of personal tax returns, two years of business tax returns if operating a company or trust, business activity statements, and financial statements prepared by an accountant. Some lenders also request evidence of business continuity such as ABN registration details, a business transaction account statement, or copies of recent invoices.
Applicants relying on rental income provide current lease agreements, property management statements covering at least three months, and evidence that rental income has been declared on the most recent tax return. If you own an investment property but have not yet completed a full financial year, some lenders will assess the income using the signed lease agreement and a letter from your property manager confirming rent has been received.
When a Broker Adds Value to Your Application
A mortgage broker can match your employment and income circumstances to the lenders most likely to approve your application and offer competitive terms. Lenders apply different policies to casual employees, contractors, and self-employed applicants, and those differences are not always visible when comparing published rates online.
We regularly see applicants in Brisbane who have been declined by one lender but approved by another with better loan features, simply because the second lender's policy accommodated their income type. A broker who understands those differences can structure your home loan application to suit your situation, confirm which documents are required, and identify whether you would benefit from waiting until probation ends or additional income history is available. That advice can determine whether you are approved at a variable rate with an offset account or declined altogether.
