Your lender will assess your refinance application based on the documents you provide, not on what you tell them verbally. Missing paperwork or incomplete records can delay approval by weeks, even when your financial position is solid.
What Documents Do You Need to Refinance a Home Loan?
Most refinance applications require proof of income, proof of identity, recent loan statements, and property valuation evidence. Lenders use these documents to confirm you can service the new loan and that the property provides adequate security. The specific documents vary depending on whether you're self-employed, have rental income, or are consolidating debt, but the core requirement is consistent: lenders need verifiable evidence of your financial position.
Consider a homeowner in South Perth who wants to refinance from a fixed rate that expired six months ago. They're now on a revert rate that's costing them an additional $400 per month. They apply to refinance to a lower variable rate, but their application stalls because they submitted payslips that don't match their bank statements. One shows salary credited fortnightly, the other shows a mix of salary and irregular overtime payments. The lender requests three months of additional payslips and proof of employment to reconcile the discrepancy. What could have been a four-week approval stretches to nine weeks, costing the borrower an extra $1,600 in unnecessary interest while the paperwork is sorted.
The documents need to align. If your payslips show bonuses or allowances, your employment letter should reference them. If your bank statements show rental income, your tax return should declare it. Lenders cross-check everything, and inconsistencies trigger requests for more information.
Income Verification for PAYG Employees
Payslips from the last three months and a letter of employment are standard for employees. The letter should state your position, salary, employment start date, and whether your role is permanent or contract. Some lenders also request Year-to-Date (YTD) summaries from your employer or your most recent tax return.
If you've recently changed jobs, you may need to provide additional documentation to show continuity of income. A gap in employment, even a short one, can prompt the lender to request an explanation or reduce the amount they're willing to lend. If you've been in your current role for less than six months, expect to provide evidence of your previous employment as well.
Bank statements are also scrutinised. Lenders look for gambling activity, frequent dishonours, buy-now-pay-later repayments, and unexplained cash deposits. If you've recently received a large deposit from family or savings, you'll need a statutory declaration explaining the source. Undeclared liabilities often surface during this review, which is why it's worth reviewing your statements before submitting them.

Income Verification for Self-Employed Borrowers
Self-employed applicants typically need two years of tax returns, two years of financial statements, and two years of tax assessments (Notices of Assessment). Some lenders also request a letter from your accountant confirming your ongoing income and business structure. If your business is a company or trust, you may also need to provide company financials and trust deeds.
The lender will assess your income by averaging your taxable income over two years, though some lenders allow you to add back certain deductions like depreciation if they don't impact cash flow. If your income has dropped significantly from one year to the next, expect questions. A declining income trend can reduce your borrowing capacity or trigger a decline, even if your current cash flow is strong.
In our experience, the most common issue for self-employed borrowers is submitting incomplete tax returns. If you lodge online through MyGov, ensure you download the full Notice of Assessment, not just the summary page. The lender needs to see the breakdown of income, deductions, and any offsets claimed.
Property Valuation and Loan Statements
Your current lender will appear on your credit file, but you'll still need to provide a recent loan statement showing the outstanding balance, repayment amount, and account number. This helps the new lender calculate your Loan-to-Value Ratio (LVR) and determine whether Lenders Mortgage Insurance (LMI) applies.
Most lenders organise their own valuation once your application is submitted, but you should still provide evidence of your property's current value if you have it. Recent sales in your street, a council rates notice showing land value, or a valuation you've commissioned privately can all support your application. If the lender's valuation comes back lower than expected, your LVR increases, and you may need to adjust your loan amount or pay LMI.
Refinancing to access equity adds complexity. If you're releasing equity to purchase an investment property, the lender will want to see the contract of sale for the new property, along with rental appraisals if you're borrowing based on projected rental income. If you're consolidating debt, they'll need statements for every liability you're paying out, including credit cards, personal loans, and car loans.
Identification and Supporting Documents
You'll need a current driver's licence or passport, plus a Medicare card or rates notice to satisfy identification requirements. If your name has changed due to marriage or deed poll, provide a marriage certificate or change of name certificate. If you're refinancing jointly, both applicants need to provide separate identification.
Some lenders also request additional documents depending on your circumstances. If you're receiving child support, you'll need a court order or Centrelink statement. If you're on a temporary visa, you'll need visa documentation and evidence of your residency status. If you've recently separated or divorced, a separation agreement or divorce order may be required, particularly if your former partner is listed on the existing loan or property title.
For those coming off a fixed rate, it's worth gathering your documents at least two months before expiry. Refinance applications can take four to six weeks to settle, and if you leave it until the last minute, you may end up on a revert rate while your new loan is processed.
How Lenders Assess Liabilities
Every credit card, personal loan, and buy-now-pay-later account reduces your borrowing capacity, even if the balance is zero. Lenders assess credit cards based on the limit, not the balance, so a card with a $10,000 limit costs you the same serviceability as if you owed the full amount. If you're not using a card, close it before applying.
Unexpected liabilities often surface during the application. A joint account with a family member, an old store card you forgot about, or a personal loan you co-signed for someone else will all appear on your credit file and affect your serviceability. Obtain a copy of your credit report before applying so you can address any issues upfront. If there are errors, dispute them with the credit reporting agency before submitting your refinance application.
When to Request a Loan Health Check
If you're unsure whether refinancing will deliver a tangible benefit, or if your financial situation has changed since you first borrowed, a loan health check can clarify your options. It reviews your current interest rate, loan features, and repayment structure against what's available in the market. It also identifies any documentation gaps before you commit to a formal application, which reduces the risk of delays or decline.
Gathering your documents before you speak to a broker speeds up the process. You don't need to submit everything upfront, but having your payslips, tax returns, and loan statements ready means your broker can give you an accurate assessment of your borrowing capacity and likely approval timeframe.

Frequently Asked Questions
What documents do I need to refinance my home loan?
You'll typically need proof of income such as payslips or tax returns, proof of identity including a driver's licence or passport, recent loan statements, and evidence of your property's value. The specific documents required depend on whether you're employed or self-employed and whether you're consolidating debt or accessing equity.
How long does it take to process a refinance application?
Most refinance applications take four to six weeks to settle, though this can extend if documents are missing or incomplete. Starting the process at least two months before your fixed rate expires gives you time to address any issues without ending up on a higher revert rate.
Do lenders check my credit cards even if the balance is zero?
Yes, lenders assess credit cards based on the limit, not the balance. A card with a $10,000 limit reduces your borrowing capacity even if you never use it. Closing unused cards before applying can improve your serviceability.
What income documents do self-employed borrowers need?
Self-employed applicants typically need two years of tax returns, two years of Notices of Assessment, and two years of financial statements. Some lenders also request a letter from your accountant confirming your income and business structure.
What happens if the lender's valuation is lower than expected?
A lower valuation increases your Loan-to-Value Ratio, which may require you to pay Lenders Mortgage Insurance or reduce your loan amount. Providing recent sales data or a council rates notice can support your application if you believe the valuation is conservative.
