VAT Tax Invoice Requirements in Nepal

Why the Tax Invoice Matters

The tax invoice performs three functions:

Seller

Evidence of taxable sale and Output VAT.

Buyer

Principal evidence supporting Input VAT claim.

IRD

Transaction-level audit trail.

Therefore:

Wrong invoice → possible Output VAT, Input VAT and audit problems for both parties.

Seller Information

The prescribed invoice format includes information such as:

• seller name;

• address;

• PAN/VAT registration number;

• contact information where applicable;

• invoice date;

• transaction date.

The current Schedule format published by IRD confirms these core fields.

Buyer Information

The invoice should include relevant buyer details such as:

• buyer/customer name;

• address;

• PAN/VAT number where applicable.

For business-to-business transactions, obtaining the correct buyer PAN is particularly important for Input VAT and system matching.

Goods / Service Description

The invoice should clearly identify the supply.

For goods, the current Rule 17 framework can require details such as:

• type;

• size;

• model;

• brand;

• relevant harmonised code information for imported items.

The description should be sufficient to establish what was actually supplied.

Avoid vague descriptions such as:

“Goods supplied”

where more precise identification is required.

Quantity and Value

A proper invoice should identify relevant:

• quantity;

• unit rate;

• value;

• VAT-exclusive amount;

• VAT amount/rate;

• total amount.

The VAT should be clearly determinable.

VAT Rate

For ordinary taxable supply: 13%

The invoice should identify VAT according to the prescribed format.

Do not charge 13% merely because the seller is VAT registered if the particular supply is:

• exempt; or

• zero-rated.

The transaction classification controls.

Invoice Serial Number

Invoice numbers should be sequential.

IRD states that invoice serial numbering should:

• start from 1;

• proceed sequentially; and

• restart from 1 at the beginning of each fiscal year.

An electronic billing system should prevent unexplained:

• duplicate invoice numbers;

• deleted invoice numbers;

• out-of-sequence numbering.

When Should an Invoice Be Issued?

For goods, IRD explains that the invoice is issued at the earlier relevant event involving:

• buyer taking/receiving goods; or

• consideration being received,

subject to the statutory time-of-supply rules.

Services have their own time-of-supply analysis.

The invoice should not simply be postponed to month-end for administrative convenience where the tax point arose earlier.

Number of Copies

The current Rule 17 framework generally requires the tax invoice to be prepared in:

Three copies

with:

• original provided to recipient;

• second retained for production to tax office when required;

• third retained for the registered person's business records.

IRD can approve additional copies where necessary.

Electronic invoice systems must preserve equivalent statutory evidence.

Tax Invoice Need Not Be Pre-certified

IRD confirms that ordinary tax invoices do not need to be separately certified by the tax office before use.

However, the invoice must still comply with:

• prescribed format;

• numbering;

• accounting records;

• electronic-billing requirements where applicable.

Simplified Tax Invoice

Retail businesses can, with the relevant tax-office approval, issue a simplified tax invoice under Rule 18/Schedule 6.

Not everyone may issue one.

IRD states that this facility is generally available to approved retail sellers selling to final consumers.

Important

A buyer obtaining a simplified tax invoice cannot generally claim Input VAT on that invoice.

The current VAT Rules expressly state that purchases supported by a simplified tax invoice do not qualify for Section 17 Input VAT deduction.

Simplified Invoice Limit

IRD's current FAQ states that a simplified invoice cannot be issued for a tax-inclusive value exceeding: NPR 10,000.

For transactions beyond the applicable limit, a normal tax invoice should be issued.

Cash Invoice vs Credit Invoice

The method of payment does not eliminate the invoice requirement.

The Schedule invoice format provides for payment-mode information such as:

• cash;

• cheque;

• credit.

A credit sale is still a taxable supply where the tax point has arisen.

VAT-inclusive Pricing

Where retail prices are presented as VAT-inclusive, the VAT component must be correctly extracted.

If total VAT-inclusive price is: NPR 113

VAT-exclusive value: NPR 100

VAT: NPR 13

Do not calculate: 13% × 113 = 14.69 because VAT is already included in NPR 113.

Debit and Credit Notes

Where taxable value changes after invoicing due to matters such as:

• return;

• discount;

• cancellation;

• price adjustment;

the correction should be made through appropriate debit/credit-note procedures rather than deleting or rewriting the original invoice.

See the VAT credit-and-debit-note guide for the adjustment requirements.

Electronic Billing

IRD increasingly regulates electronic billing and computerised invoices.

The current tax administration also includes:

• CBMS/electronic invoice requirements for designated taxpayers;

• electronic billing permission;

• statutory penalties for manipulation/deletion of electronic billing data.

Therefore businesses should use accounting software that preserves:

• invoice number;

• issue date;

• audit trail;

• cancellation history;

• user/action history.

Invalid Invoice Risk

A buyer's Input VAT may be challenged if:

• supplier is not validly VAT registered;

• invoice is not a valid tax invoice;

• PAN is incorrect;

• invoice has been altered;

• transaction did not occur;

• purchase is unrelated to taxable activity;

• supporting evidence is missing.

A tax invoice is necessary evidence, but invoice possession alone does not prove entitlement to Input VAT.

Common Errors

Issuing VAT invoice while not VAT registered

Using old invoice format

Missing buyer PAN

Non-sequential invoices

Restarting invoice sequence during the same fiscal year without basis

Using simplified invoice where full tax invoice is required

Claiming Input VAT from simplified invoice

Deleting invoice instead of using correction procedures

Further guidance and practical checks

A compliant VAT invoice is both a tax document and an accounting control document. Billing software should preserve the statutory format, sequential numbering and immutable transaction history.
