When you apply for a home loan, lenders spend more time reviewing your income and employment than almost any other part of your application.
The reason is straightforward. Your ability to repay the loan depends on regular income, and lenders need confidence that your employment will continue beyond settlement. What can look like a strong financial position on paper might not meet a lender's serviceability criteria if your income structure is complex or your employment type falls outside their preferred categories.
How Lenders Categorise Employment Types
Lenders divide employment into four main categories: permanent full-time, permanent part-time, casual, and self-employed. Each category has different documentation requirements and different implications for your borrowing capacity.
Permanent employees with a consistent salary usually find the application process more straightforward. Lenders typically ask for payslips covering the most recent pay cycle and a letter from your employer confirming your position, salary, and employment start date. If you have been in your role for less than six months, some lenders will ask about your previous employment history to establish continuity in your field.
Casual and contract workers face additional scrutiny. Lenders want to see at least six to twelve months of consistent income in the same role or industry before they will include that income in their serviceability calculations. For casual workers, only the base hourly rate is usually accepted unless you can demonstrate a consistent pattern of overtime or penalty rates over an extended period.
Self-Employed Income Assessment
Self-employed borrowers need to provide tax returns and financial statements, usually covering the most recent two financial years. Lenders assess your net profit after business expenses rather than your gross revenue, which means your borrowing capacity may be lower than you expect if your business shows high turnover but modest profit margins.
Consider a Brisbane-based tradesperson who operates as a sole trader and earns a gross income of around $120,000 annually. After claiming vehicle expenses, tools, insurance, and other legitimate business costs, their taxable income sits closer to $75,000. Most lenders will use that lower figure when calculating how much they can borrow, even though the business generates significantly more revenue. Some lenders will add back certain depreciation expenses, but the assessment still centres on what appears in your tax return rather than your bank statements.
How Bonuses, Overtime, and Allowances Are Treated
Not all income is weighted equally. Lenders apply different percentages to non-guaranteed income depending on how reliably it appears in your pay history.
Base salary is counted at 100%. Bonuses and commissions are usually assessed at 80% of the average you have earned over the past two years, provided you can show they are a regular part of your remuneration. Overtime is treated similarly, but only if it appears consistently across multiple pay cycles. A one-off period of high overtime in the lead-up to your application will not carry much weight.
Allowances such as shift loading or tool allowances are assessed individually. Some lenders include them in full, while others exclude them entirely or apply a discount. If allowances make up a significant portion of your income, it is worth checking how your preferred lender treats them before you lodge a home loan application.

Probationary Periods and Job Changes
Starting a new job does not automatically disqualify you from borrowing, but it does introduce complexity. Most lenders prefer to see you past your probation period before they approve a loan. If you are still on probation, some will proceed if you can show you have worked in the same industry or role type for several years and the change represents career progression rather than a complete shift in direction.
Switching industries or moving from permanent employment to contract work mid-application can trigger a reassessment. Lenders may pause your application until you can provide updated payslips or an employment contract showing your new income and employment terms.
Income Verification and What Lenders Check
Lenders do not rely solely on the documents you provide. Most will contact your employer directly to confirm your employment status, and some run additional checks through third-party verification services that pull data from the Australian Taxation Office.
If there is a discrepancy between what you have declared and what the lender verifies, your application will be delayed or declined. It is not uncommon for applicants to round up their income slightly or include irregular payments they expect to continue. Those adjustments can create problems later in the process, particularly if the lender's verification shows a lower figure than what was used in the initial serviceability assessment.
Multiple Income Sources
If you have more than one job, lenders will usually consider both incomes provided each role meets their minimum criteria for hours worked and length of tenure. A permanent part-time role combined with casual weekend work can strengthen your application, but only if you can show both roles have been maintained consistently for at least six months.
Rental income from an investment property is typically assessed at 80% of the gross rent to account for periods of vacancy and maintenance costs. Centrelink payments, including Family Tax Benefit and Child Care Subsidy, are included by most lenders, though the percentage used varies. Some lenders exclude government payments entirely if they form your primary income source.
Why Employment Stability Matters More Than Income Alone
A higher income does not always translate to a higher borrowing capacity if your employment history shows frequent job changes or gaps. Lenders look for continuity because it suggests lower risk. Someone earning a lower salary in a role they have held for five years may be viewed more favourably than someone earning significantly more but who has changed employers three times in the past two years.
In our experience, this is where applicants with non-traditional career paths run into difficulty. If your work history includes periods of travel, study, or career changes, be prepared to explain those gaps in writing and provide context around your current employment stability.
How Lenders Calculate Serviceability
Once your income is verified, lenders apply a serviceability buffer to determine how much you can borrow. They calculate your repayments using an interest rate that is higher than the actual rate you will pay, usually by adding a buffer of around 3%. This ensures you can still afford the loan if interest rates rise.
Your existing debts are factored in as well. Credit card limits are treated as if they were fully drawn, even if you carry no balance. Personal loans, car loans, and Buy Now Pay Later accounts all reduce your borrowing capacity. If you have multiple credit commitments, it may be worth paying them down or closing unused accounts before you apply.
Documentation Checklist for Your Application
Gathering your documents before you speak to a broker will speed up the process. For most applicants, you will need recent payslips, a letter from your employer, and your most recent tax return or Notice of Assessment. If you are self-employed, add two years of financial statements and your business ABN details.
Bank statements covering the past three months are required to verify your savings and demonstrate consistent income deposits. Lenders will review your spending patterns as well, looking for regular gambling transactions, undeclared debts, or other red flags that might affect your ability to repay the loan.
What to Do If Your Income or Employment Changes
If your circumstances change between pre-approval and settlement, contact your broker immediately. A reduction in hours, a move to a lower-paid role, or the loss of a second income source can all affect your approval. Lenders reassess your position before settlement, and any material change will need to be disclosed and reviewed.
Voluntarily leaving your job after receiving pre-approval but before settlement can result in the lender withdrawing their offer. If you are planning a career change, it is usually worth waiting until after settlement to make the move, or at least discussing the timing with your broker beforehand.
Your income and employment form the foundation of your home loan application. Understanding how lenders assess these factors means you can prepare your documents, address any gaps in your employment history, and position yourself as a strong borrower before you begin the formal process.

Frequently Asked Questions
How long do I need to be in my job before applying for a home loan?
Most lenders prefer you to have completed your probation period, which is usually three to six months. If you are still on probation but have worked in the same industry for several years, some lenders will still proceed with your application.
Do lenders count overtime and bonuses as income?
Lenders typically assess overtime and bonuses at around 80% of the average earned over the past two years, provided they appear consistently in your pay history. One-off payments or irregular bonuses carry less weight in serviceability calculations.
What documents do self-employed borrowers need to provide?
Self-employed applicants usually need to provide two years of tax returns, financial statements, and their business ABN details. Lenders assess net profit after expenses rather than gross revenue when calculating borrowing capacity.
Can I apply for a home loan if I have casual employment?
Yes, but lenders generally require at least six to twelve months of consistent casual income in the same role or industry. Only your base hourly rate is usually accepted unless you can demonstrate a sustained pattern of additional hours or penalty rates.
What happens if I change jobs after getting pre-approval?
You must notify your broker immediately if your employment changes after pre-approval. Lenders reassess your circumstances before settlement, and any material change in income or employment status may affect your approval.
