Executive Summary & Key Takeaways
- Monthly VAT returns (Mushak 9.1) must be filed on or before the 15th day of the following month—even if there were zero transactions (Nil return).
- Always issue and collect formal Mushak 6.3 Tax Invoices to protect input tax rebates and client VDS deductions.
- Reconcile your 12 monthly Mushak 9.1 returns against your annual financial statements before closing the year.
1. e-BIN Registration & Choosing the Right VAT Regime
Under the Value Added Tax and Supplementary Duty Act 2012, eligible businesses must obtain a 13-digit Business Identification Number (e-BIN) from the National Board of Revenue (NBR). Depending on your annual turnover, nature of supply (manufacturing, trading, service, or import/export), and statutory thresholds, your entity may fall under standard VAT registration, truncated rates, or Turnover Tax.
Note that entities opting for reduced/truncated VAT rates generally cannot claim input tax credit (rebate), whereas standard-rate (15%) registered taxpayers can offset eligible input VAT against output VAT.
2. Essential Mushak Forms Every SME Should Maintain
VAT compliance is built on contemporaneous register maintenance rather than year-end reconstruction. Key statutory forms include:
- Mushak 6.1 (Purchase Register) & Mushak 6.2 (Sales Register) or Mushak 6.2.1 (Combined Register for traders).
- Mushak 6.3 (Tax Invoice): Issued with every taxable supply of goods or services.
- Mushak 4.3 (Input-Output Coefficient Declaration): Mandatory for manufacturers and commercial suppliers prior to supplying goods.
- Mushak 6.6 (Withholding VAT Certificate): Issued when VAT is Deducted at Source (VDS) by a withholding entity.
- Mushak 9.1 (Monthly VAT Return): Submitted on or before the 15th of the following month.
3. Protecting Your Input Tax Credit (Rebate)
A frequent source of VAT disputes in Bangladesh is the disallowance of input tax credits during audit. Under the VAT & SD Act 2012, claiming an input tax rebate requires strict adherence to procedural conditions: the purchase must be declared in your Mushak 4.3, supported by a valid Mushak 6.3 invoice or Bill of Entry, recorded in Mushak 6.1, paid through banking channels where required, and claimed within the statutory tax periods.
