VAT & Excise
VAT Assessment, Tax Audit and IRD Investigation in Nepal
Applicable framework: VAT Act, 2052 — Sections 20–23 Current source basis: Consolidated VAT Act through Finance Act 2082 + Finance Act 2083 overlay
VAT is principally a self-assessment tax, but the Tax Officer may make an assessment where statutory grounds exist.
Section 20 includes circumstances such as:
VAT return not filed;
incomplete or incorrect VAT return;
false/fraudulent return;
reasonable grounds to believe VAT has been understated or is incorrect.
Before final assessment, the taxpayer must be given an opportunity to submit its explanation/evidence under the applicable assessment procedure.
1. Self-assessment Comes First
A VAT-registered taxpayer:
calculates taxable sales;
calculates Output VAT;
claims eligible Input VAT;
files Schedule 10;
pays net VAT.
That filed return is the taxpayer's self-assessment position.
But IRD can subsequently verify it.
2. When Can IRD Assess VAT?
Section 20 permits assessment where, among other matters:
Return not filed
Taxpayer does not file within the statutory period.
Incomplete return
Required information is missing.
Erroneous return
Return contains incorrect figures/treatment.
False return
Return contains false/fraudulent information.
Understated VAT
Tax Officer has reasonable grounds to believe VAT liability has been understated or otherwise incorrectly reported.
3. Assessment Evidence
Section 20 permits assessment based on matters including:
proof/evidence of transactions;
tax-audit findings;
comparable transactions/tax paid by similar taxpayers,
subject to the statutory framework.
The assessment should not be arbitrary.
The tax authority must establish the basis for the proposed VAT adjustment.
4. Burden of Proof
Section 20 expressly places the burden of proof on the Tax Officer for the tax assessment made under that framework.
This does not mean that the taxpayer can refuse to provide records.
Section 23 gives IRD significant inspection/audit powers.
The practical position is: IRD must support its assessment
while taxpayer must maintain and produce required VAT records.
5. Defence Opportunity
The current VAT assessment procedure gives the taxpayer a period to submit evidence/clarification before the final assessment order.
The current Rules framework reflects a: 15-day defence period
in the assessment process.
The taxpayer should use this stage seriously.
Do not submit:
“We disagree.”
Instead prepare:
transaction reconciliation;
tax invoice;
purchase/sales book;
bank evidence;
Input VAT evidence;
customs data;
legal arguments.
6. Assessment Limitation
VAT Section 20 contains an ordinary: four-year assessment limitation framework subject to statutory exceptions such as fraud and specific reassessment situations.
For a disputed limitation issue, review any applicable court decision together with the statutory wording and the filing history.
The precise limitation date should therefore be calculated from:
filing history;
applicable statutory wording;
relevant judicial interpretation;
rather than assuming the Income Tax reassessment rule applies identically to VAT.
Important
Income Tax normal reassessment limit = current three-year framework does not mean: VAT limit also became three years.
They are different Acts.
7. Fraud Exception
Where the original VAT assessment/return is affected by fraud, the ordinary limitation protection can differ.
Therefore businesses should not describe the four-year rule as:
“IRD can never assess VAT after four years.”
8. Jeopardy Assessment — Section 22
Where IRD believes tax collection is at risk because the taxpayer may:
leave Nepal;
transfer property;
conceal/remove assets;
the Tax Officer, with required approval, may use the Section 22 jeopardy-assessment mechanism.
This is an exceptional protective assessment process.
9. Inspection and Audit — Section 23
IRD has statutory powers to inspect and audit VAT compliance.
This can include verifying:
VAT registration;
tax invoices;
sales;
purchases;
inventory;
Input VAT;
imports;
business premises;
books and records.
A taxpayer preventing lawful Section 23 inspection can face separate penalties.
10. Common VAT Audit Reconciliations
IRD may compare:
Sales
VAT return ↔ financial statements
Purchases
VAT purchase book ↔ accounts
Customs
imports ↔ Input VAT
TDS
service transactions ↔ Income Tax withholding
Bank
collections ↔ turnover
Inventory
purchases + opening stock − sales ↔ closing stock
Electronic Billing
invoice sequence ↔ sales declaration.
Businesses should perform these reconciliations before IRD does.
11. Common Audit Issues
sales suppression;
missing VAT invoices;
duplicate Input VAT;
blocked Input VAT;
fake invoices;
purchases unrelated to business;
incorrect zero-rating;
exempt/taxable misclassification;
undeclared branches/warehouses;
invalid Credit Notes;
unexplained inventory differences;
customs/VAT mismatches;
electronic-billing manipulation.
12. Assessment Example
VAT return showed: Output VAT:
NPR 1,000,000
Input VAT: NPR 800,000
VAT paid: NPR 200,000
IRD audit disallows: NPR 150,000 of Input VAT
Revised VAT: Output VAT: NPR 1,000,000
Allowed Input VAT: NPR 650,000
VAT liability: NPR 350,000
Already paid: NPR 200,000
Additional principal VAT: NPR 150,000
Then separate:
additional fee;
interest;
penalty, if applicable
must be calculated according to the Act.
13. Administrative Review
A taxpayer dissatisfied with VAT assessment can apply for Administrative Review under Section 31क within the statutory period.
The VAT Act separately provides the review/Revenue Tribunal route.
Use the separately applicable:
VAT Appeal & Administrative Review
resource rather than assuming the Income Tax appeal page applies unchanged.
14. VAT Audit Defence File
VAT registration certificate
VAT returns
Sales books
Purchase books
Tax invoices
Credit/Debit Notes
Customs declarations
Input VAT reconciliation
Output VAT reconciliation
Financial statements
Bank reconciliation
Inventory records
Contracts
Zero-rate evidence
Exemption evidence
Electronic billing data
IRD notices
Response chronology
15. Common Errors
Applying Income Tax limitation periods to VAT
Ignoring a proposed assessment until the final order
Submitting only ledger printouts without underlying invoices
Claiming Input VAT solely because a supplier invoice exists
Failing to reconcile turnover across VAT, TDS and financial statements
16. Further guidance and practical checks
VAT assessment is transaction- and invoice-intensive. The best defence is a contemporaneous audit trail that reconciles invoices, accounting records, customs data, inventory and filed VAT returns.
