Why Lenders Treat Bonus Income, Commissions, and Allowances Differently for Australian Expats – And How It Affects What You Can Borrow
TL;DR: Key Takeaways
- Lenders rarely count 100% of bonus, commission, or allowance income for Australian expats – policies vary significantly across lenders [1][5].
- The type of income component, how long you have received it, and the currency it is paid in all affect whether a lender will include it in your assessment [7].
- Some lenders will not count certain variable income types at all, while others require additional approval before including them [4].
- Borrowing power, LVR, and approval outcomes depend on individual circumstances and lender policy, which is subject to change and varies by lender and borrower profile.
- Matching your specific income structure to the right lender requires knowledge of how 40+ institutions apply their policies – not information that is publicly published.
Why Does Variable Income Get Treated Differently in the First Place?
Australian lenders are required to assess whether a borrower can sustainably service a loan over its full term. Base salary is straightforward: it is fixed, contractually guaranteed, and predictable. Bonus income, commissions, and allowances are none of those things. From a lender’s perspective, a $50,000 annual bonus that arrived three years in a row might not arrive in year four, especially if the borrower changes roles or their employer adjusts its incentive structure.
This becomes more complex for expats because overseas income already carries an additional layer of uncertainty – foreign exchange risk, varying employment frameworks, and income documentation in a different language or format. Many expats are shocked when their borrowing capacity does not match their expectations, precisely because banks assess expat income differently than they would for a domestic borrower [6].
The result is a layered assessment process where lenders apply different treatment to each income component, and no two lenders apply the same rules.
How Do Lenders Assess Each Income Component?
Building on the volatility concern above, the practical application of these policies differs by income type. The table below summarises how variable income components are commonly treated, noting that specific policies are subject to change and vary by lender and borrower profile.
| Income Component | Common Lender Treatment | Key Risk Factors for Lenders |
|---|---|---|
| Base Salary | Generally counted in full, subject to foreign income shading | Currency risk, employment stability overseas |
| Bonus Income | Often requires 1-2 years of history; may be partially counted or require additional lender approval [1] | Irregular, discretionary, not contractually guaranteed |
| Commission Income | Some lenders will not count it at all; others count an average over 1-2 years [4] | Performance-dependent, highly variable year to year |
| Work-Related Allowances | May require additional lender approval; treatment depends on allowance type [1] | May not transfer with a role change; some are non-taxable and treated differently |
| Overtime Income | Often requires additional approval and evidence of regular receipt [1] | Employer-discretionary, not guaranteed |
| Salary Sacrifice / Company Car | Some lenders will gross this up as additional income; others ignore it [2] | Non-cash; valuation inconsistencies across lenders |
Where a lender does agree to include bonus or commission income, they will typically want to see it documented across at least two payslips or two years of payslips, plus potentially tax returns or employer letters confirming it is an ongoing part of the package [5][7].
What Does “Additional Approval” Actually Mean for Expats?
A related but distinct question is what happens when a lender places a variable income component into a category requiring additional approval. This is not a minor procedural step. It means the income component is escalated to a credit team or senior underwriter for manual review, which introduces subjectivity into the assessment.
For an expat applying for a mortgage UAE-side or from any other overseas hub, this adds time, documentation requirements, and an element of uncertainty. The lender may ultimately count the income in full, count a portion of it, or exclude it entirely. The outcome is not predictable without knowing that lender’s current internal policy and credit appetite [3].
This is why lender selection is not a secondary decision for expats with complex income structures. It is the primary one.
How Does Foreign Income Shading Compound the Problem?
Stepping back from the specific income types, a separate concern is how lenders apply foreign income shading on top of these assessments. Most Australian lenders do not count 100% of foreign income when calculating borrowing power. They apply a discount to account for currency fluctuation risk and cross-border income uncertainty.
The practical effect is a compounding one:
- First, only a portion of the variable income component may be counted (or none at all).
- Then, the total recognised income figure is further reduced by the lender’s shading policy for foreign currency income.
- The result is a borrowing capacity that can be materially lower than a simple calculation based on your gross salary package would suggest [6].
The degree of shading applied depends on the currency, the country of employment, and the specific lender’s policy at the time of application. These policies are not published and are subject to change.
What Can You Do to Maximise Your Assessed Income?
Building on the shading issue, the harder question is whether anything can be done to present variable income more favourably. The answer is yes, but it requires preparation well before you apply.
Practical steps to improve how lenders view your variable income:
- Document consistency: Two or more years of receiving the same bonus or commission income, with payslips and tax records to match, gives lenders the pattern of regularity they need to include it [7].
- Obtain an employer letter: A letter from your employer confirming that a bonus, commission, or allowance is a contractual or standard part of your remuneration package can make a material difference to how a credit assessor treats it [5].
- Choose the right lender first: Some lenders accept bonus and commission income as part of their standard assessment; others require escalation or exclude it entirely [3][4]. Identifying which lender’s policy matches your income structure before you apply is far more effective than appealing a low assessment after the fact.
- Understand what can be grossed up: Certain non-cash components like a company car or salary sacrifice arrangements may be recognised by specific lenders as additional income, which can lift borrowing power [2]. Not all lenders apply this treatment.
Frequently Asked Questions
It depends on the lender and your documentation. Many lenders require bonus income to have been received consistently over one to two years before counting it in a serviceability assessment. Some require additional credit approval before including it. Others may count it in full if properly documented [1][5].
Some lenders will include commission income based on an average over one to two years; others will not count it at all [4]. The outcome depends on the lender selected, the consistency of the income, and how it is documented. This is one of the clearest cases where lender selection determines the result.
Allowances received as part of an overseas salary package can be accepted for loan servicing purposes, but many lenders require additional approval before including them [1][5]. The type of allowance and whether it is taxable in your country of residence can affect how it is assessed.
Most Australian lenders apply a discount to foreign income to account for currency risk. This discount is applied on top of any partial recognition of variable income components. The combined effect can significantly reduce assessed borrowing power compared to a gross salary calculation. Specific shading rates depend on individual lender policy and are subject to change [6].
Lenders typically want multiple payslips showing the income, two years of employment history where possible, and may request an employer letter confirming the income is a regular part of your remuneration package. Requirements vary by lender [7][5].
The treatment of UAE-sourced income under an expat mortgage UAE application follows the same framework as other foreign income, but specific lender policies around currency (AED), documentation formats, and income verification can differ. Some lenders are more familiar with UAE salary structures, including housing and car allowances, than others [3].
Submitting multiple simultaneous applications is generally not advisable. Working with a specialist broker who already knows which lenders are most likely to count your specific income components, and applying to the most suitable lender first, is a more considered approach. This is general information only and not personal credit advice; speak with a specialist broker for guidance specific to your situation.
