How it works

NBFC internal audit needs a workbook that connects the RBIA audit universe to loan-level testing. The same file should show how governance, onboarding, disbursement, collections, asset classification, provisioning, treasury, returns and ITGC evidence connect.

The Excel export gives auditors separate sheets for engagement scope, RCM rows, loan-file testing, NPA/IRACP recomputation, collections reconciliation, ECL/provision tie-out, ALM/treasury/returns and monitoring exceptions. It is a workpaper starting point and must be tailored to the applicable RBI directions.

Worked example

A CA firm is performing quarterly internal audit for a middle-layer NBFC with MSME loans, vehicle finance and personal loans.

Common mistakes

Using a statutory-audit checklist as RBIA scope
NBFC internal audit/RBIA needs recurring control, risk management and follow-up evidence, not only year-end financial statement support.
Testing NPA from one report only
DPD, borrower-level classification and interest reversal should be tested across loan master, repayment schedule, classification extract and GL.
Ignoring outsourcing and digital partners
Collection agencies, sourcing partners, digital-lending partners and service providers can carry material operational and compliance risk.
