Reading income evidence without rewriting the underwriting call
File testers should test whether income proofs support the affordability worksheet—not substitute their own credit appetite.
A financial audit of loan origination applications often spends the most time on income. That is where hopeful assumptions hide: screenshots without dates, employer letters that predate the application by a year, or bank statements that show inflows from unnamed sources.
Stay inside the policy
Your job as reviewer is to ask whether the pack meets the evidence standard written in the credit policy. If the policy accepts two recent payslips, test for that. If it requires six months of statements for self-employed borrowers, do not quietly accept three because the approval already happened.
Common gaps in Thai consumer packs
- Salary slips that omit employer tax identifiers
- Statements cropped so account holder names are missing
- Affordability worksheets using promotional installment amounts
- Reused income packs from a prior facility without a freshness check
Tone in the exception log
Write “income evidence does not meet policy clause 4.2” rather than “borrower looks overstated.” The first helps remediation; the second invites debate about credit taste. Keep the underwriting judgment with the bank—your audit of the loan origination application is about evidence and process.
