If part of your pay comes from overtime, bonuses, commissions or allowances, your overtime and bonus income may help your car loan application, but lenders do not always treat it like base salary. Variable pay can lift your borrowing power, yet it is often looked at more cautiously because it can change from one month to the next.
This guide explains how that income shows up in your records, why a lender may count it differently, and what you can do to present it clearly. It is general information, not advice about your own circumstances.
The short answer
Quick answer: Lenders generally treat base salary as the most reliable income. Overtime, bonuses, commissions and allowances may also be counted, but often only where they are regular and documented, and some lenders may count only part of them. Payslips, your ATO income statement and a consistent history make variable pay easier to assess.
How much of a typical pay packet is overtime
The Australian Bureau of Statistics publishes two measures that show the gap between ordinary pay and overtime. In its Average Weekly Earnings release for May 2026, published on 13 August 2026, full-time adults' average weekly ordinary time earnings were $2,083.70, up 3.7% over the year. Full-time adult average weekly total earnings, which add overtime to ordinary time earnings, were $2,156.50 in original terms.
That puts the average overtime component for full-time adults at about $72.80 a week. For most people, overtime is a small top-up on a much larger base. For some workers in shift-based or seasonal jobs it is a much bigger share, and that is exactly where the way a lender treats it starts to matter.
Two details from the ABS methodology are useful here. First, ordinary time earnings already include items such as penalty payments, shift and other allowances, commissions, and bonuses related to the pay period. Second, the survey excludes irregular and infrequent payments such as annual bonuses, and the ABS advises caution when turning weekly earnings into an annual figure. Lenders face the same problem: a single good week, or a once-a-year bonus, does not show what you will reliably earn.
Do lenders count overtime for a car loan
Many lenders may count overtime, but how much they count depends on the lender and on your history. Common approaches include:
- counting regular overtime in full where it is a normal part of the role, such as rostered overtime in some industries
- counting only a portion of overtime to allow for the chance it drops away
- averaging overtime over a longer period, such as the year to date or the previous financial year
- leaving overtime out where it is recent, irregular or hard to verify
Each lender sets its own policy, so the same payslip can produce different borrowing power estimates with different lenders. That is one reason it can help to compare car loan lenders before you apply, rather than relying on a single assessment.
Bonuses and commissions
Bonuses and commissions are usually assessed with more care than overtime because they can be lumpy. A lender may want to see that a bonus has been paid in more than one year, or that commission income has been steady over a period, before relying on it.
If you are paid partly or mostly by commission, expect to be asked for more documents than someone on a fixed salary. If you have just moved to a commission-based role, a lender may lean mainly on your base pay until a pattern builds up. Our guide to a car loan on probation or in a new job covers how lenders may view a recent change of role.
Allowances
Allowances cover a wide range of payments, and not all of them are income in the same sense. Some, like a tool or qualification allowance, are paid steadily with your wages. Others, like travel or overtime meal allowances, reimburse costs you incur for work.
A lender may count allowances that are ongoing and not tied to a specific expense, and may set aside allowances that simply cover work costs. If your payslip shows several allowances, it helps to know which ones are regular and which ones depend on particular duties.
What your ATO income statement shows
If your employer reports through Single Touch Payroll, your yearly figures appear as an income statement in ATO online services through myGov. According to the ATO's guide to accessing your income statement, it separates your salary and wages into components including gross pay, overtime, paid leave, bonuses and commissions, directors' fees and salary sacrifice. Allowances are listed separately by type and added together as a Total Allowances Amount.
The ATO also explains that the income statement is updated each time your employer pays you, and that after the end of the financial year it is marked "Tax ready" once your employer has finalised it. For a car loan application, a finalised statement for the previous year can be a clear record of how much of your income came from each source.
The ATO's salary or wages instructions for the 2026 tax return confirm that commissions and bonuses are declared as salary and wage income. If you have not lodged yet, our article on the 31 October 2026 tax return deadline and car loans explains why an up-to-date notice of assessment can help.
How variable pay can affect serviceability
Serviceability is the lender's check that you can afford the repayments on top of your existing commitments and living costs. When part of your income is discounted or left out, the income side of that calculation shrinks, while your expenses stay the same. The result can be a lower maximum loan amount, or a request for a larger deposit.
This is why two people on the same total pay can get different answers. One may earn mostly base salary, while the other relies on overtime or bonuses that a lender only partly counts. Our guide to car loan borrowing power on an average salary walks through how lenders compare income with commitments, and the car loan repayment calculators let you test different loan amounts against the income you can document.
It can be sensible to work out a budget using your base pay alone, then treat regular overtime as a buffer. If the repayments only work when every overtime shift comes through, the loan may be harder to keep up with in a quiet period.
How to present overtime and bonus income
A clear application helps a lender assess variable pay quickly. Steps that can help include:
- Gather recent payslips that show overtime, bonuses or commissions as separate lines, ideally covering more than one pay cycle
- Download your income statement from myGov for the last financial year, and check it is marked "Tax ready"
- Keep your notice of assessment handy as a second record of the year's total income
- Ask your employer for a letter confirming that overtime is regular or that a bonus scheme is ongoing, if that is the case
- Explain any one-off amounts, such as a back payment or a single large bonus, so they are not mistaken for regular pay
- Be accurate about your expenses, because a lender will weigh them against whatever income it accepts
If you also have income from a second employer or casual shifts, our guides to a second job car loan and car loans for casual employees cover how lenders may look at those.
Where salary packaging fits
Salary packaging changes what appears on your income statement, because sacrificed amounts are shown separately and taken out of the total gross amount. If you are thinking about a novated lease instead of a car loan, it is worth understanding how each arrangement affects both your take-home pay and the income a lender sees.

The bottom line
Overtime, bonuses, commissions and allowances are real income, and many lenders may take them into account. The key is showing that they are regular and well documented. Payslips, a finalised ATO income statement and a clear explanation of any one-off payments give a lender what it needs to assess your variable pay fairly, and budgeting on base pay first helps keep the repayments manageable if the extra hours dry up.
