Refinance Cashback: Eligibility and Costs

Refinance cashback is a lender-funded cash payment for moving an eligible home loan to that lender under a promotion’s terms. Approval alone doesn’t secure the payment. The loan must meet the offer’s application, settlement and payment conditions.

The incentive must outweigh switching costs and any higher ongoing costs. A cashback loan can cost more than a loan without an incentive. Compare equivalent products over the same period, then repeat the calculation with no cashback before recommending the refinance.

How Refinance Cashback Works

The lender pays refinance cashback after the eligible loan settles and the offer’s conditions are met. The payment often goes into a nominated transaction account, so it usually arrives separately from the funds that discharge the old loan.

Different home loan offers change the comparison in different ways.

• A cash payment provides a stated amount after a qualifying transaction.
• A rate discount changes the interest charged on the outstanding loan.
• A fee waiver removes a specified charge. It doesn’t cover other switching costs unless the terms say so.
• A broker rebate is paid under the broker’s own arrangement. Its payer, timing and repayment terms need a separate record.

Count each benefit once. If a fee is already waived in the cost estimate, don’t subtract the waiver again as cashback. A retention payment from the existing lender is also a separate offer, with its own conditions.

An Approved Loan That Settles Too Late

In this hypothetical case, an offer requires application by 31 August and settlement by 30 September. A $600,000 refinance is approved on 20 September but settles on 4 October. The offer promises $3,000 only if both dates are met.

The approval letter proves credit approval. It doesn’t prove an extension of the cashback deadline. Keep the applicable offer terms, application receipt, settlement confirmation and any written lender agreement extending eligibility for this loan.

Without an extension that covers the payment, assess the refinance with $0 cashback. If switching costs are $1,200, the cash position changes from a $1,800 surplus to a $1,200 cost. Recalculate the ongoing savings and discuss the revised outcome with the client before proceeding where the delay is known in advance.

Eligibility and Common Exclusions

Cashback eligibility depends on the specific offer and the transaction that settles. Match the client’s application to the offer terms, including how the lender defines new lending and the application date.

Eligibility check	What the broker must establish
Minimum debt	The eligible refinanced amount meets the threshold. Check whether additional lending or multiple splits count
New-to-lender status	The existing loan comes from an eligible external lender. An existing deposit account alone doesn’t establish ineligibility
Product and purpose	The actual loan product, occupancy and repayment type qualify
Loan-to-value ratio (LVR)	The debt as a percentage of the lender’s assessed property value sits within the offer’s limit
Application and settlement	The lender records the required application event and the loan settles within both calendar and elapsed-day limits
Channel	The promotion applies to the route used, such as a broker, branch or direct online application
Borrower eligibility	The borrowers meet the offer and loan rules for residency, legal entity and ownership
Prior incentives	Every applicant meets restrictions on earlier cashback, rebates or other promotions

Exclusions are offer-specific. An internal refinance can fail the external-lender requirement even when it creates a new loan account. A related brand can also count as the same lending group.

For a trust or company borrower, check both the entity applying and the eligible product list. Bridging and construction loans can be excluded even when ordinary residential loans qualify. An ownership change can alter the transaction’s purpose, so establish whether the lender treats it as an eligible refinance.

Late settlement and previously paid incentives are separate checks. Passing a minimum-debt or LVR test doesn’t waive either restriction. Use the offer version that applies to the client’s dates, rather than copying rules from a different promotion.

Payment Conditions and Clawbacks

Payment conditions decide when cashback arrives and whether the borrower must repay it later. Establish the eligible receiving account and the payment trigger before settlement, then record the expected payment date.

Check whether the terms require an account in a borrower’s name at settlement, a nominated direct-credit destination or a claim submitted by the broker. If repayment conduct is a condition, record the required repayments and the period they cover. Keep the receiving account open for the required period and reconcile the payment against its statement.

As at October 2026, IMB Bank’s cashback terms, updated 15 May 2026, require an eligible IMB transaction account on settlement day. Payment is due within 60 days of settlement. Borrowers must repay 50% of the cashback if the eligible loan ends within 12 months, including through full repayment or refinance.

For multiple eligible loans under one IMB application, that repayment applies if all those loans end within the 12 months. The amount enters the final loan payout. Keep this borrower cashback obligation separate from any lender commission clawback owed by the broker.

A clawback is not a universal feature of home loan cashback offers. Read the exact repayment clause and distinguish it from reversal for fraud, illegality or failure to meet eligibility. A lender’s right to reverse an invalid payment doesn’t by itself create a general early-exit penalty.

If an eligible payment is overdue, give the lender the application identifier, settlement date and receiving-account details with the applicable terms. Ask for the unmet condition or payment status in writing. Record the cashback as outstanding until the account statement shows it was paid.

Calculate the Net Refinance Cost

Add switching charges to ongoing loan costs, then subtract only the incentive the borrower is entitled to receive. Moneysmart’s switching guide also warns that extending the remaining loan term can increase total interest.

Start with the old lender’s discharge fee and any fixed-rate break cost. Add the new loan’s application, valuation and settlement charges, legal costs and government mortgage registration or discharge charges. Include any lenders mortgage insurance (LMI), which protects the lender, and the package or account fees over the comparison period.

Obtain the actual charges for the security and transaction. Don’t treat cashback as cash available to pay settlement costs when it arrives later. If fees are added to the new loan, include the interest charged on those fees.

A Cashback Loan Against a Lower-Rate Loan

This hypothetical Australian-dollar example compares two otherwise equivalent interest-only loans over three years. Each loan has a constant $600,000 balance and the same features, with $1,200 in switching costs. Rates remain unchanged, fees are paid from cash and neither loan has an offset balance or early-exit charge.

Option A pays $3,000 cashback, charges 6.10% per year and has a $300 annual package fee. Option B has no cashback, charges 5.90% per year and has no package fee. These are fictional figures, not lender quotes or a recommendation to use interest-only repayments.

Three-year cost	Option A: cashback	Option B: no cashback
Interest	$109,800	$106,200
Switching charges	$1,200	$1,200
Package fees	$900	$0
Cashback deducted	$3,000	$0
Total cost before tax	$108,900	$107,400

Interest is $600,000 multiplied by the annual rate and three years. Option A costs $1,500 more over the period despite the cashback. Its extra annual cost is $1,200 in interest plus $300 in fees, so the $3,000 incentive covers two years of that difference.

Option A costs $111,900 with $0 cashback, or $4,500 more than Option B. A delayed payment leaves the borrower funding costs and repayments until it arrives. If the payment is reduced, subtract the confirmed amount and repeat the comparison.

For principal-and-interest loans, use an amortisation calculation because the balance falls with repayments. Compare the same remaining term and include the remaining balance at the end of the period. A lower monthly repayment caused by resetting the loan to 30 years doesn’t establish a cheaper refinance.

Tax Questions About Cashback

Use a before-tax comparison until the client’s tax adviser assesses the actual incentive and circumstances. Give the adviser the offer and payment records together with the loan purpose. Don’t assume that every cashback payment is tax-free or that every switching expense is immediately deductible.

For an investment or mixed-purpose loan, retain records showing how the refinanced debt and any additional funds are used. The Australian Taxation Office (ATO) separates income-producing and private borrowing when explaining rental-property interest in its interest expenses guidance. That interest question is separate from the treatment of the incentive itself.

Suitability Beyond the Incentive

A suitable refinance must meet the client’s objectives and lending needs even when the cashback is delayed, reduced or unpaid. Assess policy fit and serviceability, which is the lender’s test of whether income can support repayments, before treating the incentive as a benefit.

Check the valuation’s effect on the approved loan amount and LVR. Compare the product features the client uses, including offset access, redraw restrictions and extra repayments. Preserve the intended remaining term unless a different term meets a documented client need.

A broker can use Bulma’s Policy Advisor to compare lender rules and retain the quoted policy wording in the file. Offer eligibility and pricing still come from the lender’s promotion and loan terms. Bulma doesn’t quote interest rates, fees or product pricing.

The Australian Securities and Investments Commission (ASIC) explains the mortgage broker’s best interests duty in Regulatory Guide 273. Keep a file note explaining the alternatives considered, the client’s objectives and why the recommended loan meets them. Record the cost result with the expected incentive and with no incentive.

If the no-cashback result changes the recommendation, resolve that risk before relying on the promotion. The refinance requirements guide covers the wider refinance process. For additional funds, the cash-out refinance guide explains purpose and evidence checks.

Verify Named Lender Refinance Offers

Separate a current promotion from an expired promotion and an unpaid entitlement under an earlier transaction. The lender examples below reflect offer pages and terms checked on 3 October 2026. They illustrate eligibility patterns, without ranking refinance deals.

ANZ and Westpac

As at October 2026, ANZ’s retained Home Loans Switching Cashback terms end the application period on 30 September 2025. That document is historical, even though its URL remains accessible. The terms also restrict included drawdowns to that date and require drawdown within 120 days of applying.

ANZ’s expired offer required at least $250,000 in new eligible lending and paid $2,000 at LVR of 80% or less. Internal group refinances, including from Suncorp or ANZ Plus, were excluded.

ANZ’s current standard refinance page promotes discounted rates and fee terms, rather than that switching payment. ANZ Plus has separate products and terms.

For an unpaid ANZ entitlement from the expired promotion, match the original application and drawdown dates to those terms. The eligible account had to exist at drawdown. The terms provide an automatic payment process within 60 days of qualifying where no valid fulfilment request has been received.

As at October 2026, Westpac’s refinance page promotes an online rate offer, with LVR and channel conditions. It doesn’t advertise a general refinance cashback payment. The rate offer excludes internal refinances within the Westpac Group.

Westpac’s earlier $3,500 cashback promotion ended for new applications on 30 June 2023, according to Australian Broker’s dated report. An unpaid payment from that promotion needs its original terms and transaction records. Today’s rate-offer conditions cannot establish an earlier cashback entitlement.

IMB Bank

As at October 2026, IMB Bank’s home loan cashback page advertises an active offer, subject to variation or withdrawal. Its terms, updated 15 May 2026, require at least $250,000 in eligible new lending and LVR no higher than 80%. They specify eligible Budget, Essentials and Fixed Rate home loans, excluding the one-year fixed product.

For applications from 15 May 2026, refinances must settle within 120 days of IMB accepting the application. There is no fixed calendar closing date in those terms. The current tiers pay $2,000 for $250,000 to $499,999, $3,000 for $500,000 to $749,999 and $4,000 from $750,000.

The offer excludes internal IMB refinances, commercial loans, self-managed superannuation fund loans, reverse mortgages, aged care loans, construction and bridging loans. A discretionary interest rate agreed in place of cashback also excludes the payment. Once an eligible application is approved, further applications including those borrowers cannot qualify in the following 12 months.

Payment goes to an eligible transaction account within 60 days of settlement, with the 12-month retention and repayment conditions described above. Compare that retained benefit against IMB’s actual loan costs and policy fit before counting it in the client’s recommendation.

CBA, Macquarie and St.George

As at October 2026, Commonwealth Bank of Australia (CBA) promotes digital products and online rate discounts on its refinance page. The page doesn’t advertise a general refinance cash payment. Historical cashback references don’t make a current application eligible, and loyalty rewards or fee rebates are separate benefits.

As at October 2026, Macquarie’s home loan page describes its loan products and refinancing options without advertising a general switching cashback payment. A broker rebate connected to a Macquarie loan needs the broker’s terms, rather than an assumption that Macquarie funds it.

As at October 2026, St.George’s refinance page promotes rates, features and refinancing options without advertising a general mortgage cashback payment. A bank-account or shopping cashback promotion doesn’t establish eligibility for home loan cashback.

For an earlier CBA, Macquarie or St.George transaction with an unpaid incentive, use the offer issued for that transaction and the evidence of meeting its conditions. Establish whether the lender or broker owes the payment. Keep the entitlement separate from today’s offers, and base the refinance decision on total cost and the client’s needs.
