Complete Guide to Nepal IRD Bill Format & HS Code Requirements 2026

For every Nepali business, creating IRD-compliant invoices is a legal requirement, not just good practice. With the phased rollout of mandatory e-billing, understanding the proper Nepal IRD bill format is essential for tax compliance and avoiding penalties. This comprehensive guide covers everything from mandatory fields and HS codes to the latest updates on e-billing, CBMS integration, and compliance reporting in 2026.

What is Nepal IRD Bill Format? (Official Requirements)

The Inland Revenue Department (IRD) of Nepal mandates specific elements that must appear on every tax invoice for VAT-registered businesses. These are prescribed by Rule 17 of the VAT Rules, 2053. Non-compliance can result in penalties during tax audits.

Mandatory Elements for IRD-Compliant Invoices:

1. 'Tax Invoice' Header clearly displayed in Nepali or English
2. Seller's Details: Business name, address, VAT/PAN number
3. Buyer's Details: Name, address, and VAT/PAN number (if registered or transaction ≥ NPR 10,000)
4. Invoice Serial Number (unique for each financial year, following fiscal year-based numbering)
5. Invoice Date and Transaction Date
6. Description of Goods/Services with quantity, unit, and rate
7. Discount (if any) shown separately
8. Taxable Value (net of discount, subtotal before VAT)
9. VAT Amount separately shown (13% standard rate)
10. Grand Total Including VAT (in words and figures)
11. Seller's Signature or authorized stamp

Understanding E-Billing and CBMS Compliance

Nepal is rapidly moving towards a fully digital tax ecosystem. The government has mandated e-billing (computerized billing) for a broader base of taxpayers to increase transparency and curb tax evasion.

What is E-Billing & Why is it Mandatory?

E-Billing replaces handwritten bills with invoices generated using IRD-approved software. It simplifies the billing process, reduces errors, and ensures tax compliance.

• Thresholds for E-Billing: Businesses with annual transactions exceeding NPR 10 crore (or NPR 5 crore for certain sectors like hotels and restaurants) must use IRD-approved billing software.
• Central Billing Monitoring System (CBMS): A centralized system developed by the IRD to monitor and manage invoices in real-time. Businesses with an annual turnover above NPR 25 crore must sync all invoices with CBMS in real-time.

Who Needs IRD-Approved Billing Software?

Using IRD-approved software is mandatory for businesses that cross the specified thresholds. The software must meet technical and legal standards to issue valid electronic invoices. Key requirements include:

• Database Security: SQL-based database, data integrity, and automated log archives.
• Invoice Controls: Fiscal year-based serial numbering, restricted reprints, and cancellation with reasons.
• Reporting & Export: Capability to generate reports in IRD-prescribed formats (e.g., Annex 5, Annex 13) and export data.
• CBMS Integration: Seamless integration with IRD's system via Web API for real-time monitoring.

For cloud-based solutions, there are additional requirements, such as the central server being located in Nepal, informing the IRD, and allowing access upon request.

Understanding HS Code for Nepal Imports/Exports

What is HS Code?

The Harmonized System (HS) Code is an internationally standardized system of names and numbers for classifying traded products. Nepal follows the HS code system for customs, with codes typically consisting of 8-10 digits.

Why HS Code Matters for Nepali Businesses:

• Customs Clearance: Required for all imports/exports
• Tax Calculation: Determines applicable customs duties and VAT
• Trade Statistics: Government tracking of trade items
• Documentation: Needed on commercial invoices and packing lists

Common HS Code Categories in Nepal:

• 0701.10.00: Seed potatoes
• 0901.11.00: Coffee, not roasted
• 1006.30.00: Rice, semi-milled or wholly milled
• 5201.00.00: Cotton, not carded or combed
• 8544.42.00: Electric conductors, fitted with connectors

How to Find Correct HS Code for Your Products

1. Visit Nepal Customs Department Website: Access the official HS code directory
2. Use Online Search Tools: International trade databases with Nepal-specific codes
3. Consult Clearing Agents: Professional advice for accurate classification
4. Check Similar Products: Reference competitors' or suppliers' documentation

IRD Compliance Reports: Annex 5 & Annex 13

For businesses using e-billing, generating correct IRD compliance reports is crucial for tax filing and audits.

• Annex 5 (Transaction Records): Auto-prepared from daily sales, purchase, and return entries. It lists all transactions for the fiscal year, including bill number, customer name/PAN, bill date, taxable amount, VAT, and total amount.
• Annex 13 (High-Value Transactions): Used to list sales, purchases, and fixed assets where the transaction value exceeds NPR 100,000 (One Lakh). This report is critical during the audit filing period.

An audit trail, which logs every action (create, update, delete) in the system, is also a key IRD requirement for maintaining data integrity and transparency.
