Why Mushak 6.3 trips up most owners
The NBR's Mushak 6.3 form looks deceptively simple — until you realise that every single sales invoice above the threshold needs the right serial, the right HS code, and the right rounding.
Below is the workflow Ryzan customers use to never miss a filing.
1. Configure your VAT rates once
Set up rates per product category: standard 15%, truncated 7.5%, zero-rated, exempt. Once configured, every invoice line auto-applies the right rate.
2. Print the right invoice format
Mushak 6.3 must include: BIN, invoice serial, item description, quantity, unit price, VAT rate, VAT amount, total. Ryzan's default invoice template ships with this layout.
3. Reconcile monthly, not quarterly
Pull the VAT summary report at month-end. Match against your sales register. Any variance? Find it now, not at filing time.
4. File from one screen
Generate Mushak 9.1 (the master return) directly from Ryzan with one click. Submit, save the acknowledgement, attach to the period.
Common mistakes that cost penalties
- Wrong HS code on imports — pull the canonical list, don't guess.
- Mixing VAT-inclusive and VAT-exclusive prices — pick one, stick to it.
- Forgetting to reverse VAT on returns — automate it via your credit-note workflow.
- Late filing — set a calendar reminder for the 15th of every month.
A quick checklist
- BIN printed on every invoice
- Serial number unbroken across the period
- All rates correctly assigned to categories
- Monthly reconciliation done by the 5th
- Mushak 9.1 filed by the 15th
