Proven tips to gather refinance documents FIFO workers need

What documents do you need to refinance a home loan as a FIFO worker?

You need to provide proof of income, proof of assets and liabilities, identification, and property information. Lenders assess refinancing applications the same way they assess purchase loans, which means they need to verify your capacity to service the new loan and confirm the security property value.

Income verification for FIFO workers involves more documentation than standard PAYG roles because your pay includes base salary, shift allowances, overtime, and potentially bonuses or living away from home allowances. Lenders shade irregular income components at different rates depending on how long you have earned them and whether they appear on your payslips continuously. Consider a fixed plant operator who has been on the same roster for 18 months with consistent shift allowances. That operator will need to provide payslips covering at least the last three months, a letter from their employer confirming the roster is ongoing, and tax documentation showing the income pattern over a full financial year. The lender will then apply a shading rate to the allowance component, typically 80% where the income has been earned continuously for six months or more, before calculating serviceability.

Most FIFO workers underestimate how much weight lenders place on demonstrating income continuity. A two-week gap between contracts, even if you moved straight into a higher-paying role, can trigger a lender to treat you as a new employee rather than someone with an established income history. That changes how they assess overtime and allowances, often reducing the usable income figure and limiting how much you can borrow when you refinance your home loan.

Payslips and employment verification for shift-based income

You need your three most recent payslips and a letter from your employer confirming your role, roster, and income structure. The payslips must show your base pay, overtime hours, shift allowances, and any other regular payments like travel or site allowances separately.

Lenders calculate annualised income by reviewing what you have earned over the payslip period and projecting it forward. If your payslips show fluctuating hours or allowances, they will average the income and apply a shading percentage. Suncorp, for instance, treats non-essential services overtime and allowances at 80% where you have earned them continuously for six months or more. Ubank applies 80% to regular PAYG overtime and shift allowances but only 50% to irregular annual bonuses verified over one year, increasing to 80% if the bonus has been paid for two consecutive years.

The employer letter needs to state your employment type, confirm whether your contract is ongoing or fixed-term, specify your roster pattern, and confirm that your current income structure is expected to continue. Where your contract is fixed-term but includes leave entitlements, some lenders will treat the income as 100% rather than shaded. If your contract does not include leave entitlements, expect the lender to apply a higher discount or request additional evidence of recurring work.

Tax returns and notice of assessment for annual income verification

You need your most recent tax return and notice of assessment to verify your total annual income, including any components that do not appear consistently on payslips. Lenders use this documentation to cross-check what you have declared on your application and to assess whether bonuses, allowances, or other variable income should be included in serviceability.

If you have been in the same role for more than two years and your income has increased year on year, the tax return strengthens your application because it shows a stable or improving income trend. If your most recent tax return shows lower income than your current payslips because you changed jobs or increased your roster mid-year, you will need to provide a detailed explanation and supporting evidence that the higher income is sustainable. In our experience, FIFO workers who move between employers or shift from part-time to full-time rosters mid-financial year often face questions during assessment because the tax return does not reflect current earning capacity.

Where your income includes a bonus, lenders will look at whether it appears in multiple tax returns. A one-off bonus paid in a single year will usually be excluded from serviceability calculations. A bonus paid in two consecutive years will typically be shaded to 80% and included, provided your employer confirms it is likely to continue.

Asset and liability statements for equity and servicing assessment

You need to provide statements for all bank accounts, credit cards, personal loans, car loans, and any other liabilities you hold. Lenders use these statements to verify your deposit or equity position, assess your spending patterns, and calculate your total debt obligations.

For refinancing, the equity calculation is central. If you are refinancing to access equity or consolidate debt, the lender will order a valuation on your property to determine its current market value and calculate how much you can borrow against it. You do not need to provide a valuation yourself, but you should have a realistic understanding of what your property is worth before you apply. Overestimating equity is one of the most common reasons refinancing applications stall.

Credit card limits are treated as if they are fully drawn for serviceability purposes, even if you pay the balance in full each month. If you hold a credit card with a $20,000 limit and you never carry a balance, the lender will still add a monthly repayment obligation to your expenses as if you owe the full $20,000. Closing or reducing credit card limits before you apply improves your serviceability and can increase the amount you can borrow or reduce the rate you are offered.

Identification and property documents to finalise the application

You need a current driver licence or passport, and you may need a Medicare card or rates notice as secondary identification. Lenders also require a copy of your current loan statement showing the outstanding balance, the interest rate, and the lender name, plus a copy of your most recent rates notice for the property you are refinancing.

The loan statement allows the new lender to calculate the exact payout figure and confirm there are no missed payments or arrears on your current loan. If you have a fixed rate loan and you are coming off a fixed rate period, check whether your fixed term has already expired or whether breaking the loan early will trigger break costs. Break costs are not part of the document checklist, but they are a cost you need to account for if you refinance before your fixed term ends.

The rates notice confirms the property address, the council valuation, and that rates are up to date. Some lenders will also request a copy of your building insurance policy to confirm the property is insured for an amount consistent with the loan size.

How lenders assess FIFO income differently when you refinance

Lenders apply income shading to calculate how much of your FIFO income they will use for serviceability. Income shading reduces the dollar figure used in the assessment to account for variability or the risk that overtime, allowances, or contract work may not continue.

Bankwest, for example, uses a dedicated FIFO income verification formula: total hours per cycle multiplied by the lowest hourly rate, multiplied by the number of working cycles per year. All hours above your minimum contracted hours are classified as overtime. Allowance and overtime income is calculated by annualising your year-to-date income, then subtracting annualised base income. This approach isolates the variable income component and applies a shading percentage to it before calculating serviceability.

CBA redirects FIFO workers with fluctuating base salary to their PAYG work-related allowances policy rather than their standard base income assessment. This distinction affects how much income is recognised and, in turn, how much you can borrow. Where your income has been consistent for 12 months or more, most lenders will shade overtime and allowances to 80%. Where your income history is shorter or your payslips show gaps, expect heavier shading or a request for additional evidence.

Income shading artificially inflates your debt-to-income ratio because it reduces the income figure used in the calculation while leaving your total debt unchanged. Since February 2026, banks have been restricted on how many loans they can write where total debt exceeds six times gross annual income. If your shaded income pushes your DTI above that threshold, mainstream banks may reduce the loan amount, increase the interest rate, or decline the application. Non-bank lenders regulated by ASIC rather than APRA are not subject to the same portfolio caps and may offer more flexibility where your DTI sits above six times income.

If you are refinancing and your income structure includes shift allowances, overtime, or contract work, the documentation process takes longer and the assessment is more detailed than it would be for a standard PAYG role. Having your payslips, employer letter, tax return, and liability statements organised before you apply speeds up the process and reduces the chance of delays or requests for additional information.
