An offset account usually reduces trail commission because most lenders pay on the loan balance after deducting linked offset savings. The lender’s commission terms decide the balance used. A client can still owe the same principal while the balance earning trail falls.
Does an Offset Account Reduce Trail Commission?
Yes, an offset account usually reduces trail commission when the lender deducts linked offset balances from the loan balance. The MFAA’s broker remuneration factsheet describes trail as payable on the outstanding balance net of offset funds.
That makes a lower trail payment consistent with a client saving money while keeping their loan. It does not, by itself, establish a refinance or a payment error. Match the loan’s commission terms to the balance reported before deciding why income fell.

How Lenders Calculate Trail on the Net Balance
Lenders that net offsets subtract the eligible linked savings from the loan balance before applying the trail rate. Some use a month-end snapshot. Others use balances across the month, so money moving in or out partway through the period changes the result.
A simple monthly estimate is net commission balance multiplied by the annual trail rate, divided by 12. A daily calculation can differ because of the days in the period and the lender’s calculation method. Keep the rate’s GST treatment and any aggregator or broker split consistent when reconciling the payment.
Hypothetical Monthly Example
Assume a $600,000 loan, a fully eligible $100,000 offset and an annual trail rate of 0.15% excluding GST. These are hypothetical figures. Assume the balances stay unchanged and the lender divides annual trail into 12 equal payments.
| Position | Balance Earning Trail | Monthly Trail, Excluding GST |
|---|---|---|
| Loan with no offset savings | $600,000 | $75.00 |
| Same loan with $100,000 in offset | $500,000 | $62.50 |
| Same loan fully offset | $0 | $0.00 |
The $100,000 offset reduces the monthly estimate by $12.50 before any aggregator or broker split. If eligible offset savings equal the loan balance throughout the calculation period, a net-balance calculation produces no trail. A fully offset position at month-end can still produce some trail under an average-balance method if earlier days had positive net debt.
Which Lenders Net Offset Balances
CBA, Bankwest and Virgin Money have published net-of-offset trail provisions in the Connective Commission Guide. The table identifies the residential provisions in that guide, rather than assuming all products or settlement cohorts share one rule.
| Lender | Trail Basis in the Published Guide | Source and Application |
|---|---|---|
| CBA | Net: month-end home-loan balance less linked MISA or Everyday Offset credit balances | Connective guide, page 36, residential trail definition |
| Bankwest | Net: average loan balance less average linked offset balances | Connective guide, page 23, eligible residential loans |
| Virgin Money | Net: daily loan balances after applicable mortgage offsets | Connective guide, page 100, residential trail |
| Macquarie | Check with the lender for the offset deduction applicable to the loan | Connective guide, page 66 specifies average daily balance for trail |
Use the terms applying to the actual loan and your aggregator agreement when reconciling a statement. A net-of-offset upfront provision does not establish how trail is calculated.
Extra Repayments, Lump Sums and Trail
A lump sum repayment or regular extra repayments reduce the actual loan principal, which lowers the balance earning trail. Offset savings remain in a separate account and can leave again. A repayment’s reduction remains unless the borrower redraws or borrows more.
If a client pays an extra $50,000 into the loan, principal falls by that amount before subsequent interest and other transactions. If they later redraw $20,000, principal rises again. Trail can then rise with the eligible balance under the lender’s terms.
Moving $50,000 from a fully eligible offset into the linked loan can leave the net commission balance unchanged. The loan principal and offset each fall by $50,000. Avoid forecasting another $50,000 reduction in trail-bearing debt for that transfer.
How Offset Shows on Aggregator Reports
Offset savings can appear as a lower commission balance and lower trail even when the client’s gross loan principal barely changes. A lump sum repayment reduces principal itself. The statement’s field definitions determine which balance you see.
Compare consecutive reports using the same loan reference and the same type of balance. A hypothetical row falling from $500,000 to $400,000 with lower trail is a signal to investigate, rather than proof of its cause.
| Observation | Next Check | What Separates the Causes |
|---|---|---|
| Commission balance falls but principal is steady | Compare the linked offset balance over the same period | More offset savings can explain the lower net balance |
| Principal and commission balance both fall | Inspect repayments and any transfer or refinance records | A lump sum pays down debt; a partial refinance moves debt elsewhere |
| Loan disappears or trail stops | Confirm account status and repayment details | A discharge closes the debt; a fully offset loan can remain open |
Track My Trail’s Quick Analysis compares two monthly aggregator reports and lists clients who paid down a large amount between them. It also separates clients who dropped off from those shown as discharged or refinanced. Use those results to choose which loans need a closer look.
With each client’s open banking consent, Refinance Finder shows their loan balance, offset and net balance beside the trail figures. Match the data’s update point to the statement period before using it to explain a movement.
If the balance does not explain the shortfall, follow the missing trail commission checks and keep the loan reference and affected periods for the aggregator enquiry.
Offset Account vs Extra Repayments: Advising Clients
Choose between offset and extra repayments according to the client’s cash needs, loan costs and tax circumstances. Both can reduce interest, but their access rules differ. Moneysmart’s offset guidance explains that offset savings remain accessible, while redraw access depends on the loan terms.
For an owner-occupier keeping an emergency fund, offset can suit money they need to access readily. Compare the expected interest saving with the offset product’s fees and any higher interest rate. A small or frequently spent balance can make the extra cost hard to justify.
For a client focused on permanently reducing debt, extra repayments can suit money they do not need back. Check repayment limits and any charges before recommending a lump sum, particularly on a fixed-rate loan. Redraw access remains subject to the lender’s rules.
For investment loans, repayment and later redraw can change the purpose of the borrowing for tax. The ATO’s guidance on interest deductions and redraw addresses the use of redrawn funds. Have the client ask their accountant about their proposed offset, repayment or redraw before treating the choices as tax-equivalent.
Use the borrower’s offset account guide for the savings mechanism and the offset versus redraw comparison for product features.
When providing regulated credit assistance, the best interests duty requires mortgage brokers to act in the consumer’s interest. A lower trail payment does not change that obligation. Sections 158LA and 158LE of the National Consumer Credit Protection Act 2009 set out the duty. Sections 158LB and 158LF require priority for the consumer where interests conflict.
Record the client’s expected savings balance, cash-access needs and the costs compared. Add the reason for recommending offset or repayments and any accountant referral. ASIC Regulatory Guide 273, Mortgage brokers: Best interests duty explains the record-keeping expectations.
Forecast Trail When Clients Build Savings
Expect lower trail when clients steadily build offset savings on loans paid on a net basis. Forecast income from the eligible net balance, with separate assumptions for savings growth and principal repayments.
Keep an offset balance separate from a permanent repayment in the forecast because the client can spend the offset savings. Model a sustained-savings case and a withdrawal case without treating either as guaranteed income. For book value, carry the lower expected trail into the cash-flow assumptions instead of valuing the gross loan balance alone.
Before updating the forecast, reconcile the latest statement to the lender’s balance method. Record whether the movement comes from offset savings, a repayment or debt moving elsewhere, then change the income assumption for that loan.
