Why lenders still need your tax returns after you file
You may assume that lodging your tax return with the Australian Taxation Office settles the paperwork. Then your mortgage broker or loan officer asks for the return, the notice of assessment and several supporting documents. It can feel like duplicated work, especially when you have only just submitted everything online.
The request is usually part of the lender’s income-verification process. A lender must establish how much you earn, whether that income is reliable and how much of it can safely support repayments. Your tax return gives a detailed record that payslips alone cannot always provide.
This applies to first-home buyers, investors, refinancers and borrowers replacing an existing home loan. It can also affect applicants with casual work, overtime, commissions, rental income or a business registered under an Australian Business Number (ABN).
The timing is rarely a sign that something is wrong with your application. In many cases, the lender wants the latest complete financial year rather than an estimate based on a newly filed return. Understanding that distinction can make the process feel far less like a bureaucratic faff.
What Your Tax Return Confirms
A tax return shows the income you declared for the financial year ending 30 June. It may include salary, business profits, rental income, dividends, trust distributions and other sources that do not appear on a standard payslip.
The lender may compare the return with your ATO notice of assessment, bank statements, payslips and employment records. This helps confirm that the figures are consistent and that the income was actually assessed, rather than simply entered as an expectation.
For employees, the return can also reveal deductions, salary-sacrifice arrangements and changes in earnings. A lender may not reduce your gross income because of every deduction, but it needs to understand the full picture before calculating borrowing capacity.
If you have recently changed jobs in Melbourne, moved from contract work to a permanent role in Brisbane, or taken parental leave, the lender may ask for extra context. A new payslip proves current employment, while the tax return helps establish your broader income history.
Why A Recently Filed Return May Still Be Needed
Lodging a return does not always mean the ATO has processed it. Your tax agent may submit it quickly, but the notice of assessment can arrive later. Until the return is assessed, a lender may treat the figures as unverified or rely on an older tax year.
There is also a difference between “most recent” and “latest available” income. If you have just lodged your 2024–25 return, the lender’s policy may still require the 2023–24 notice of assessment because that is the latest document already processed in its system.
Some lenders accept an ATO receipt, tax-agent confirmation or portal record while waiting for the assessment. Others will not formally use the new figures until the notice is available. The answer depends on the lender, the type of application and whether your income has become more or less predictable.
This is why a broker may request documents that appear repetitive. A clear document checklist can help you distinguish between proof that the return was lodged and proof that the ATO has assessed it.
How Income Type Changes The Assessment
PAYG employees generally have the simplest path. Lenders may use recent payslips, an employment letter and an income statement from myGov, then cross-check those details against tax information. Overtime, bonuses and commissions often require a longer history because they can vary from year to year.
Self-employed borrowers usually face more detailed checks. A lender may ask for two years of personal tax returns, business returns, notices of assessment, profit-and-loss statements and business activity statements. It may average profits across years or use the lower figure if earnings have fallen.
A borrower with an ABN may have strong cash flow but still show modest taxable income after business expenses. Some lenders add back selected expenses, such as depreciation, while others apply stricter rules. Your accountant’s explanation can help, but it does not replace the lender’s own assessment.
Rental income is treated carefully too. Banks may accept only a portion of rent to allow for vacancies, management fees and maintenance. A tax return helps show the property’s expenses, while a rental statement or lease confirms current income.
The Tax Details That Can Affect Borrowing Power
Taxable income is not identical to the money landing in your bank account. Salary packaging, fringe benefits, investment losses and business deductions can change the figure a lender uses. A home loan assessment therefore looks beyond a single annual number.
HECS-HELP or other study debt is another Australian consideration. Your repayment obligation may be calculated from your income, even if no separate direct debit appears on your bank statement. This can reduce serviceability and affect the amount a lender is prepared to approve.
Lenders also assess existing commitments, including credit cards, car finance and personal loans. Even an unused credit-card limit can be treated as potential debt. When your tax return indicates higher income but your liabilities have also grown, the extra earnings may not produce the borrowing increase you expected.
Australian banks generally apply a serviceability buffer above the proposed interest rate. This is designed to test whether you could cope with higher repayments, rather than assuming today’s rate will last for the entire loan term.
What To Send And What To Keep
Send the complete documents requested, rather than selected pages. A lender may need the full tax return, every notice of assessment, an income statement, business schedules or rental details. Cropped screenshots can create delays because important identifiers or totals may be missing.
Check that names, addresses and financial years match across your documents. If your current address is in regional Queensland but your tax records show an old Sydney property, explain the change early. A short note can prevent the lender from treating an ordinary move as an inconsistency.
Keep proof of recent changes too. This could include a promotion letter, a signed employment contract, a new lease, an updated BAS or evidence that a one-off deduction will not recur. Such documents are especially useful when this year’s income looks different from the previous return.
Avoid altering figures or estimating annual income without supporting evidence. If the return contains an error, speak with your accountant before sending an explanation to the lender. A correction lodged with the ATO is easier to assess than unexplained differences between documents.
Practical Steps For A Smoother Application
A few organised steps can reduce delays and make the lender’s questions easier to answer:
- Ask whether the lender needs the newly lodged return, the previous assessed return or both.
- Download your ATO notice of assessment and income statement from myGov where available.
- Give your broker a short explanation for major income changes, job moves or business fluctuations.
- Include supporting records for overtime, commissions, rent, dividends and self-employment income.
- Check all debts, credit limits and HECS-HELP details before the lender completes serviceability calculations.
| Applicant situation | Documents commonly requested | Reason the lender asks |
|---|---|---|
| PAYG employee | Payslips, income statement, tax return or notice of assessment | Confirms salary and variable income |
| Casual or commission worker | Employment evidence, payslips and one or more tax returns | Tests whether earnings are consistent |
| Sole trader | Personal and business returns, notices of assessment and BAS | Verifies sustainable business profit |
| Property investor | Tax return, rental statement and lease | Checks rent and property expenses |
| Recent return lodged | Lodgement receipt plus prior assessed documents | Separates submitted figures from verified figures |
Tax returns are therefore requested because they provide an independently recorded view of your financial position, not because the lender doubts that you filed. Until the ATO assessment is available, the lender may need older records or additional evidence to make a responsible decision.
Being asked for the documents again is common across home loans and refinances. Preparing the return, notice of assessment and supporting income records together can help your application move forward without unnecessary back-and-forth.
