Mushak 6.5 is a VAT form prescribed by the National Board of Revenue (NBR) in Bangladesh, used as a goods transfer invoice for centrally registered entities. It documents the movement of goods between different units, branches, or locations under the same central VAT registration. The form records details such as the description of goods, quantity, value, and transfer destination. Maintaining Mushak 6.5 ensures proper tracking of internal transfers, supports accurate inventory records, and helps businesses remain compliant with the Value Added Tax and Supplementary Duty Act.
