Priya works as a registered nurse across two casual positions at a Sydney hospital. Her fortnightly income is strong and consistent, but when she approached her bank directly, she was told her casual status made things complicated. She left without an answer and assumed a home loan was out of reach.

It was not out of reach. Within six weeks of speaking with Laxmi Home Loans, Priya had pre-approval with a lender whose policy was well-suited to her employment structure and income history. Her situation was not unusual. Many Australians with variable or non-standard income face the same experience when they go directly to a bank.

The problem is not the income. The problem is choosing the wrong lender or presenting the application incorrectly.

What Is a Complex Income Assessment?

A complex income assessment is the process lenders use when your earnings are not fixed or consistent throughout the year. Unlike borrowers who receive the same salary every fortnight, lenders need additional evidence that your income is stable and likely to continue before they will include it in your borrowing capacity calculation.

Complex income is not rare. A significant portion of the Australian workforce earns income that does not fit the traditional PAYG salary model. Lenders have established processes for assessing it. The challenge is that those processes differ substantially between lenders, which is why the same borrower can receive very different borrowing capacity results depending on which institution they approach.

Why Your Borrowing Capacity Varies Between Lenders

This is one of the most important things to understand as a borrower with complex income. Your borrowing capacity is not a fixed number. It depends heavily on which lender assesses your application and how their credit policy treats your specific income type.

The difference between these approaches can amount to hundreds of thousands of dollars in borrowing capacity. This is exactly why comparing lenders matters, and why submitting a single application directly to your everyday bank is rarely the most effective strategy for borrowers with complex income.

How Lenders Assess Commission and Bonus Income

Commission income is one of the most common forms of complex income in Australia. Many professionals earn a base salary plus commission, while others earn commission only. Both situations are assessable, though the documentation requirements differ.

Most lenders want to see that your commission has been received consistently over time. The standard approach is to average the last two financial years of commission earnings. Where there is a significant difference between years, some lenders use the lower figure. Others apply a shading percentage, accepting only 80% or 90% of the averaged amount to account for variability.

Bonus income is treated more cautiously. Where bonuses are contractual and have been paid consistently for two or more years, some lenders will include them. Discretionary or one-off bonuses are typically excluded. Providing payslips, employment contracts confirming the bonus structure, and two years of tax returns gives lenders the clearest possible picture of your earnings.

How Lenders Assess Contract Workers

Contract workers are one of the fastest-growing employment groups in Australia, particularly in information technology, engineering, healthcare, and government sectors. Lenders have developed specific policies to assess this type of income, though those policies vary considerably.

The key factors lenders consider for contract workers include the length of contracting history, industry experience, the duration remaining on the current contract, renewal history, any gaps between contracts, and future work prospects in the field.

Where appropriate, lenders may annualise your current income based on a standard working year. For example, if you earn a daily rate of $600, a lender may calculate your annual income as $600 multiplied by approximately 220 working days. If you have multiple contract renewals with the same client, or a long history of continuous contracting in the same industry, this strengthens your application significantly.

Short gaps between contracts are not automatically disqualifying. Providing a clear explanation and evidence of ongoing work history reduces lender concerns about income continuity. Industries with high demand for contractors, such as healthcare and technology, are generally viewed more favourably.

How Lenders Assess Casual Workers

Casual employment is common across nursing, aged care, education, hospitality, and support work. Many casual workers earn reliable, long-term incomes despite their employment classification. Lenders recognise this, though the required employment history varies between institutions.

Some lenders accept casual income after six months if the employment history demonstrates stability and consistent hours. Others require twelve months or longer. The key factors are your current employer, the length of your casual engagement, the regularity of your hours, your year-to-date income, and demand for your occupation.

If your casual hours are consistent each fortnight, many lenders treat your income similarly to a permanent part-time arrangement. Registered nurses and healthcare workers in casual roles often benefit from lender policies that specifically recognise the demand stability of their occupation.

What Happens If You Have Multiple Income Sources?

Many borrowers combine income from two casual jobs, a salary plus commission, casual employment plus rental income, or contract work plus investment returns. Each income source may be assessed differently, and the total picture presented to a lender requires careful structuring.

The most common challenge is that a borrower presents all income sources to a lender whose policy is conservative across several of those categories. A broker can identify lenders whose policies are most favourable to your specific combination of income types, and ensure each source is presented with the right documentation to support inclusion in the assessment.

How the Assessment Process Works

1. 1
   Employment stability review. The lender reviews your employment history to determine whether your income is sustainable and likely to continue. Industry, tenure, and occupation demand all form part of this assessment.
2. 2
   Document collection. Supporting documents typically include recent payslips, your employment contract, tax returns for the last two years, a Notice of Assessment, bank statements covering three to six months, and group certificates or income statements.
3. 3
   Assessable income calculation. Depending on lender policy, income may be averaged over two years, annualised from a current rate, shaded by a percentage, or based on the lower of two years. The method applied varies between lenders.
4. 4
   Serviceability assessment. The lender applies their servicing calculator, which accounts for your existing debts, living expenses, credit history, dependants, and a mandatory interest rate buffer above the loan rate.
5. 5
   Lender credit policy applied. Final eligibility is determined by the lender’s credit policy, including their specific rules on employment type, income history length, and industry.

Common Challenges and How to Address Them

Short Employment History

Changing jobs recently does not automatically mean your application will be declined. Some lenders focus on industry experience rather than time with a specific employer. A nurse who has moved between hospitals is viewed differently from someone who has changed industries entirely. A broker can identify lenders whose policies suit your specific situation.

Income Fluctuations Between Years

Seasonal or performance-driven income naturally varies year to year. Providing a longer income history helps demonstrate overall stability. Where one year is significantly lower than another, it is important to explain the reason, whether that was parental leave, illness, or a specific business event. Context helps lenders make a fair assessment.

Gaps Between Contracts

Contractors commonly experience short breaks between engagements. A brief gap in a high-demand industry is generally less concerning to lenders than a gap in a declining sector. Providing a written explanation alongside evidence of ongoing work history and future contract prospects reduces lender concern about continuity.

Multiple Income Sources

Where income comes from two jobs, a salary plus commission, or employment plus rental income, each source needs to be assessed and documented separately. Combining all income into one figure without proper support documents often leads to lenders excluding some sources entirely. Read our guide on how banks calculate borrowing power to understand how each income stream is treated.

How to Strengthen Your Application

• Maintain stable employment. Avoid changing jobs immediately before applying unless necessary. If a change is planned, speak with a broker first about timing.
• Reduce existing debts. Lower credit card limits and personal loan balances where possible before applying. Unused credit limits reduce your borrowing capacity even if the balances are zero.
• Build a genuine savings history. Regular deposits into a savings account over at least three months demonstrate financial discipline. Lenders treat genuine savings favourably.
• Keep accurate records. Retain payslips, contracts, and tax documents from previous years. Missing documents are one of the most common causes of delays and declined applications for complex income borrowers.
• Choose the right lender. The lender you choose has more impact on your outcome than almost any other factor when your income is variable. This is where working with an experienced broker adds the most value.
