Mushak 6.2 is a VAT form prescribed by the National Board of Revenue (NBR) in Bangladesh, used as a Sales Book for businesses registered for VAT. It records details of all taxable sales, including invoice numbers, buyer information, product descriptions, quantities, values, and applicable VAT amounts. Maintaining Mushak 6.2 ensures accurate sales tracking, proper VAT calculation, and compliance with the Value Added Tax and Supplementary Duty Act. This form is essential for audit readiness and transparent reporting to the NBR.
