E-Billing / Electronic Invoicing in Nepal: IRD Requirements Explained
Walk into most supermarkets, restaurants, or retail chains in Nepal today, and the bill you receive is generated by software connected directly to the Inland Revenue Department's system. This is e-billing in Nepal, and it has moved from being a large-business requirement to something a growing number of small and mid-sized businesses now need to comply with. This guide covers who is required to use e-billing, how to identify approved POS billing software in Nepal, the penalties for non-compliance, and how the whole system connects back to your VAT reporting.
What Is E-Billing and Why IRD Introduced It
Electronic invoicing, often referred to as e-billing or Central Billing Monitoring System (CBMS) integration, requires a business to generate sales invoices through software that transmits transaction data to IRD's central system, either in real time or at short intervals. The purpose is straightforward: it gives tax authorities a direct, tamper-resistant view of actual sales volume, which significantly reduces underreporting of VAT and income.
Who Is Required to Use E-Billing / POS Software
IRD has progressively expanded the scope of mandatory e-billing, and the following categories are typically covered:
Large taxpayers and businesses registered under the Large Taxpayer Office, supermarkets, department stores, and organized retail chains, restaurants, bars, and hotels, particularly those operating multiple branches, businesses in sectors that IRD has specifically notified through circulars as required to adopt CBMS-linked billing, and VAT-registered businesses above certain turnover levels, as periodically defined by IRD notices.
Because this list is expanded through periodic IRD notices rather than a single fixed rule, any VAT-registered business experiencing steady growth should check whether it now falls under a mandatory category, rather than assuming last year's exemption still applies.
How E-Billing / POS Systems Work
Step 1 — Sale is made at the counter: A customer's purchase is entered into IRD-approved point-of-sale (POS) software rather than a manual or unlinked billing system.
Step 2 — Electronic invoice is generated: The software issues a digital bill carrying a unique transaction identifier and the applicable VAT breakdown.
Step 3 — Data syncs with IRD: Transaction details are transmitted to IRD's central monitoring system, either instantly or at scheduled intervals, depending on the software's integration method.
Step 4 — Figures feed into VAT reporting: Because sales data is already captured centrally, it feeds into the business's periodic VAT return, reducing manual reconciliation and making discrepancies easier for IRD to flag.
Approved Billing Software
IRD maintains and periodically updates a list of approved billing and POS software vendors that meet its technical integration standards. A business cannot simply use any invoicing tool and call it compliant — the software must specifically be certified for CBMS or e-billing integration with IRD. Before adopting any billing system, it is worth confirming its current approval status directly through IRD, since vendor approvals can be added, updated, or withdrawn over time.
Penalties for Non-Compliance
Businesses that fall under a mandatory e-billing category but continue issuing manual or non-integrated invoices can face monetary penalties per violation or per tax period, increased scrutiny and a higher likelihood of a full tax audit, disallowance of certain input credits if invoicing does not meet the prescribed format, and reputational risk with corporate clients who require IRD-compliant invoices for their own compliance. Given how easily IRD can now cross-check a business's declared turnover against third-party card and payment data, operating outside the e-billing requirement when it applies is an increasingly risky position to be in.
How E-Billing Links to VAT Reporting
Because every e-billing transaction is already logged with IRD at the point of sale, the system creates a running record that can be compared against what a business later declares in its periodic VAT return. Significant mismatches between the two — declared sales that are lower than the transactions IRD already has on file — are a common trigger for audit selection. In this sense, e-billing does not just change how a bill looks to the customer; it fundamentally changes how closely a business's day-to-day sales are monitored against its formal tax filings.
Frequently Asked Questions
Do small retailers need e-billing too?
Not automatically. Mandatory e-billing has historically targeted larger taxpayers, chains, and specifically notified sectors first, but the scope has been expanding over time. A small retailer should periodically check current IRD notices, since crossing a certain VAT turnover level or operating in a newly notified sector can bring even a small business into the mandatory category.
Can a business use its own custom-built billing software?
Only if that software goes through IRD's certification process and meets the required technical specifications for data transmission and invoice format. Businesses cannot assume an in-house system is automatically compliant just because it generates a bill.
Does e-billing replace the need to file VAT returns?
No. E-billing feeds data into IRD's monitoring system and supports the accuracy of VAT reporting, but the business is still required to file its periodic VAT returns in the normal manner. E-billing makes those returns easier to verify — it does not remove the filing obligation itself.
