VAT Audit in Bangladesh: NBR Audit Procedures & Defense Strategy

A VAT audit conducted by the Customs, Excise and VAT Commissionerate or the Audit, Intelligence & Investigation Directorate (AIID) examines discrepancies between reported sales, input tax credits, and audited annual balance sheets. Knowing your legal rights and presenting a cohesive documentation defense prevents catastrophic revenue demands.

Statutory Timeline: Under Section 90, tax authorities may conduct a comprehensive VAT audit covering up to five preceding financial years.

Common Inspection Triggers

  • Sharp deviations in input-output coefficient ratios without declared price revisions.
  • Continuous accumulation of negative VAT balances (excess input tax rebates) over consecutive months.
  • Unreconciled turnover differences between annual audited accounts and cumulative Mushak 9.1 filings.
  • Failure to deposit Value Deducted at Source (VDS) collected from suppliers within statutory deadlines.

Preparing Your Audit Defense Pack

  • Consolidate all 12 monthly Mushak 9.1 returns alongside original Treasury Challans.
  • Provide cross-matched bank statements confirming that all sales revenues passed through corporate accounts.
  • Organize supplier Mushak 6.3 invoices validating all claimed input tax rebates.
  • Draft a formal legal reply addressing audit queries item by item under Section 83/84.
