Mortgage brokers operate with a revenue model that has very few parallels in other industries: upfront commissions paid at settlement, trail commissions that recur monthly for the life of the loan, and clawback provisions that can claw back upfront commissions when a loan is repaid early. Getting the bookkeeping treatment right requires understanding both the commercial arrangements and the applicable revenue recognition standard.
Upfront Commission Income
Upfront commissions are paid by the lender at loan settlement. Under AASB 15 Revenue from Contracts with Customers, the performance obligation associated with an upfront commission is typically satisfied at or around settlement — the broker has identified the customer, facilitated the application, and settled the loan. Revenue is therefore recognised at settlement.
For tax purposes, upfront commission income is assessable income under s.6-5 of ITAA 1997 on receipt (for cash-basis smaller practices) or when the entitlement arises (for accruals-basis practices). Most mortgage brokerage businesses of any size use the accruals basis, so the commission should be recognised as income when earned (at settlement) regardless of whether the lender has paid yet.
Journal entry at settlement (before cash received):
DR Commission Receivable [upfront commission amount]
CR Upfront Commission Revenue [income recognised]
When cash is received from the lender:
DR Bank [amount received]
CR Commission Receivable [receivable cleared]
Trail Commission Income Recognition
Trail commissions are monthly payments from lenders based on the outstanding loan balance, typically ranging from 0.15% to 0.20% per annum of the outstanding balance. For a $500,000 loan at 0.15% trail, the monthly trail commission is approximately $62.50 — modest individually, but material in aggregate across a large book of loans.
Under AASB 15, trail commission is a variable consideration that depends on future loan performance (the loan remaining active, the borrower not repaying early). The output method of revenue recognition is the most appropriate approach: trail commission is recognised as it is earned each period, based on the outstanding balance at that time.
For tax purposes, trail commission income is assessable in each period it is received or becomes receivable. Unlike upfront commissions, trail commissions have an ongoing performance obligation (the broker's obligation to service the client relationship over the loan term). This distinction is relevant to any dispute about timing of income recognition.
Practical accounting note: Many brokers operate on a cash basis for trail commissions because the amounts per period are small and the administrative cost of accruing them monthly exceeds the benefit. This is acceptable for smaller practices but should be a deliberate policy choice documented in the practice's accounting policies.
Clawback Provisions: Contra Income or Provision?
Clawback is the most distinctive feature of mortgage broker bookkeeping. If a borrower refinances or repays their loan within a specified clawback period (typically 12–24 months), the lender claws back all or part of the upfront commission from the broker.
The two approaches to clawback accounting:
Contra income approach (most common): When a clawback is notified, the amount is recorded as a reduction of commission revenue (contra income) in the period the clawback occurs:
DR Clawback Expense / Contra Commission Revenue [amount clawed back]
CR Bank / Commission Payable [cash returned to lender]
Provision approach (more technically correct under AASB 15): At the time of recognising upfront commission income, estimate the expected clawback rate based on historical experience and recognise a provision for expected clawbacks as a reduction of variable consideration. This smooths the P&L and provides a more accurate picture of net commission income:
[At settlement, recognising upfront commission net of expected clawback:]
DR Commission Receivable [net expected commission]
DR Clawback Provision [expected clawback amount]
CR Commission Revenue [gross commission recognised]
The provision approach requires the broker to have reliable historical data on clawback rates. For established brokerages, this is readily available. For newer businesses, the contra income approach is simpler and defensible.
For income tax purposes, the ATO's view is that commission income is assessable when earned (at settlement) and a clawback repayment is a deduction in the year it is paid (not an amendment to the prior year's income). This timing asymmetry is manageable with good record-keeping.
Aggregator Fees
Mortgage brokers typically operate under an aggregator (ACL holder) who provides the licence, lender panel, and compliance infrastructure. The aggregator charges a membership fee and/or takes a clip of commissions (typically 10–20% of the broker's upfront and trail commissions).
Aggregator fees are deductible business expenses under s.8-1 of ITAA 1997. They are typically structured as:
- A fixed monthly membership fee (deductible as incurred)
- A percentage clip on each commission payment (deductible as incurred, often netted against the gross commission by the aggregator before remitting)
Where the aggregator remits net of their clip, the broker should gross up the revenue and record the aggregator clip as an expense — not recognise only the net amount as income. This ensures the P&L accurately reflects gross commission rates and gives the broker visibility over their clawback-adjusted net position.
PAYG: Employed Brokers vs. Self-Employed Brokers
Mortgage brokerage businesses often operate with a mix of employed mortgage brokers and self-employed brokers who operate under a sub-aggregator arrangement. The PAYG treatment differs significantly:
Employed mortgage brokers: The employing entity withholds PAYG from salary or commission payments, pays SGC at 11.5%, and is liable for payroll tax if the wages threshold is exceeded. Standard employer obligations apply.
Self-employed brokers (operating through their own ABN or company): No PAYG withholding, no SGC obligation from the principal brokerage. However, the broker is responsible for their own quarterly PAYG instalments, and the personal services income rules under Subdivision 84-A of ITAA 1997 may apply if the broker derives more than 50% of their income from one principal.
Professional Indemnity Insurance
Professional indemnity (PI) insurance is a mandatory expense for AFSL/ACL-holder mortgage brokers under the Corporations Act 2001 and ASIC requirements. PI insurance premiums are fully deductible under s.8-1 of ITAA 1997. For brokers who prepay an annual premium, the prepayment rules under s.82KZMD of ITAA 1936 apply — the deduction may need to be spread over the period of cover if the prepayment period exceeds 12 months or the amount exceeds the threshold.
