5 Payslip Red Flags Every Mortgage Broker Should Spot Before Submitting

One in four Australian mortgage applications is delayed or rejected due to income documentation issues. Most payslip issues show themselves before submission — you just need to know how to identify them. Here are five loan application red flags and how brokers use advanced risk detection to identify them within seconds.

Red Flag #1: Income That Doesn't Add Up Between Pay Periods

What it looks like: Gross pay of $3,200 for most periods — then suddenly $5,800 for one period, followed by $3,100 the next.

Lenders frequently check applications because inconsistent income records between pay periods rank among the most frequent reasons for inquiries. A sudden income increase usually results from a bonus, overtime, or back-pay — but these must be treated differently from standard base salary. Some banks will only use base salary and exclude all forms of variable pay.

What to do: Use a consecutive payslip analysis across at least three pay cycles. Document and explain all irregularities and established one-time income sources.

Red Flag #2: Recent Job Changes or Unexplained Employment Gaps

What it looks like: Payslip from employer A dated March. Payslip from employer B dated May. A 6-week gap with no documentation.

Lenders want to see stable income. A job change within the last three to six months — particularly across industries — raises questions about employment continuity. Most lenders apply a probation period rule: if your client has been in their role less than three to six months, the income may not be accepted at face value.

A payslip dated more than 90 days before submission may be rejected outright under the 90-day rule. Lenders will assume the worst case when they find a gap between payslips that lacks leave documentation.

What to do: Collect at least two to three consecutive payslips from the current employer. For job changes, collect an employment contract or offer letter with salary details, start date, and probation requirements.

Red Flag #3: YTD Figures That Don't Match the Pay Rate

What it looks like: Gross weekly pay: $1,200. Pay date is Week 30 of the year. Expected YTD: ~$36,000. Actual YTD shown: $28,400.

This is a significant danger signal that most people cannot detect through regular examination. The payslip presents a regular pay rate which does not match the actual YTD figures, creating a mathematical discrepancy. This can indicate unpaid leave, decreased work hours, role changes, or a modified payslip.

Lenders and payslip fraud detection algorithms are tuned specifically to catch this discrepancy.

What to do: Run a YTD income verification check on every payslip before submission. BrokerMaite analyses per-period pay, YTD totals, pay dates, and tax withheld to identify mathematical errors before they become your responsibility.

Red Flag #4: HECS/STSL Deductions That Are Invisible on the Application

What it looks like: Client earns $95,000 gross. HECS repayments of $6,000/year appear on payslip YTD. Application submitted without disclosing the debt.

Many borrowers fail to disclose HECS and STSL deductions visible on their payslips. Lenders calculate serviceability based on net income after all commitments, and HECS repayments count. A person earning $95,000 must pay HECS repayment amounting to 6.5%, which equals $6,175 annually or $513 monthly.

What to do: Always check the payslip for HECS/STSL YTD before submitting. Payslip analysis software automatically detects this element.

Red Flag #5: Employer Details That Don't Match

What it looks like: Payslip says 'ABC Constructions Pty Ltd'. PAYG certificate says 'ABC Construction Services'. ABN doesn't match ASIC records.

Lenders now actively investigate employer detail discrepancies as part of payslip fraud detection. Any mismatch between registered names and trading names requires explanation before lenders will proceed.

What to do: Check the payslip employer ABN against the Australian Business Register before submitting. Payslip verification software automatically detects ABN mismatches and formatting errors.

Why These Red Flags Cost More Than Just Time

Application delays lead to settlement and processing delays. Rejections damage client trust and credit records. Repeated lender inquiries damage your professional relationship with credit teams. The brokers who consistently achieve clean first-submission approvals are the ones who catch these issues before the lender does.
