VAT billing in Nepal has specific requirements. Here's exactly how to create compliant VAT invoices.

Mandatory Invoice Fields

Every VAT invoice must include:

1. Business Details: - Your business name and address - PAN/VAT number - Contact details

2. Invoice Header: - "Tax Invoice" or "कर बीजक" - Unique invoice number from IRD-registered series - Date in BS (Bikram Sambat)

3. Customer Details: - Customer name - Customer PAN (for B2B sales above threshold) - Delivery address

4. Line Items: - Product/service description - Quantity and unit - Rate per unit - Taxable amount - VAT amount (13%) shown separately

5. Totals: - Subtotal (before VAT) - VAT amount - Grand total - Amount in words

VAT Calculation

Standard calculation: - Item price: NPR 1,000 - VAT (13%): NPR 130 - Total: NPR 1,130

VAT-inclusive pricing: If your price already includes VAT: - Total price: NPR 1,130 - VAT component: NPR 1,130 ÷ 1.13 = NPR 130 - Net amount: NPR 1,000

Invoice Numbering

Invoice numbers must: - Be from IRD-registered series - Be unique (no duplicates) - Reset each fiscal year (Shrawan 1) - Run sequentially with no gaps

Example: FY2082/83-001, FY2082/83-002, etc.

NitiERP POS handles this automatically, resetting numbers each fiscal year.

Credit and Debit Notes

When needed: - Return/cancellation → Credit note - Price increase → Debit note - Correction → Appropriate note

Requirements: - Must reference original invoice - Must adjust VAT registers - Cannot simply delete original

Common Mistakes

  • Missing PAN on B2B invoices
  • Incorrect VAT calculation
  • Gaps in invoice numbering
  • Not resetting numbers in new fiscal year
  • Editing invoices instead of issuing notes

Digital Requirements

Nepal is moving toward mandatory e-invoicing through CBMS. Using IRD-approved software ensures: - Compliant invoice formats - Real-time CBMS reporting - Automatic fiscal year management - Built-in validation
