A tax audit notice from the IRD can feel alarming, but it usually isn't a surprise if you understand what typically triggers a review — and it's entirely manageable if you respond within the right deadlines. The bigger risk isn't the audit itself; it's missing a response window or letting the statute of limitations catch you off guard. Here's how the process actually works, and how to prepare before a notice ever arrives.
Types of Audits (Desk Review vs Field Audit)
The IRD generally conducts two broad categories of review, differing in scope and intensity:
A desk review is often triggered by something specific and narrow — a mismatch between your declared income and a third party's TDS filing, for example — and can frequently be resolved by submitting the requested clarification or document. A field audit is more involved, typically covering a fuller review of business records, and is more likely for larger businesses, specific high-risk sectors, or cases with more significant discrepancies.
Response Deadlines After Receiving a Notice
Whenever the IRD issues a formal notice — whether requesting clarification, additional documents, or informing you of a proposed reassessment — the notice itself will specify a response deadline, commonly ranging from a matter of days to a few weeks depending on the nature and complexity of the request. Missing this deadline can result in the IRD proceeding with an assessment based solely on the information already available to it, which is often less favourable than if you had responded with your own supporting evidence.
If you genuinely need more time to gather documentation, it is generally far better to request an extension in writing before the deadline passes than to simply miss it and hope for leniency afterward.
Statute of Limitations for Reassessment
Tax authorities don't have unlimited time to reopen an old filing. Nepal's Income Tax Act generally sets a statutory limitation period within which the IRD can reassess a previously filed and accepted return — beyond this window, absent specific exceptions such as fraud or concealment, the assessment is generally considered final and cannot ordinarily be reopened.
This is precisely why maintaining organised records for several years back matters — not just for the current filing, but because a reassessment notice can, within the statutory window, relate to a return filed a few years earlier.
Appeal Deadlines and Process (Revenue Tribunal)
If you disagree with a final assessment order issued after an audit, Nepal's tax system provides a structured appeal path:
Administrative review: An initial request for review or reconsideration can often be made to the IRD itself within a specified period after the assessment order.
Appeal to the Revenue Tribunal: If the matter remains unresolved, a formal appeal can be filed with the Revenue Tribunal within the prescribed appeal deadline from the date of the final administrative decision — missing this window generally forfeits the right to appeal through this channel.
Given the technical and time-sensitive nature of tax appeals, engaging a licensed tax advocate or professional early in the process — ideally as soon as a disputed assessment is received — significantly improves the chances of a well-prepared and timely appeal.
How to Prepare Documentation in Advance
The best defence against a stressful audit response window is preparation well before any notice arrives:
• Maintain organised, dated records of invoices, bank statements, and TDS certificates for each fiscal year, ideally digitised and backed up.
• Reconcile your own records against third-party TDS filings periodically, rather than only at year-end, to catch mismatches early.
• Keep copies of all filed returns and assessment orders — these are frequently referenced again in the event of a later audit or dispute.
• Establish a relationship with a tax professional before you need one urgently, so that a notice doesn't require starting from scratch under time pressure.
Frequently Asked Questions
Does receiving an audit notice mean I've done something wrong?
Not necessarily — many notices arise from routine data mismatches or random selection criteria rather than deliberate wrongdoing, and are often resolved with straightforward clarification.
Can I request more time to respond to an audit notice?
Extension requests are often possible if submitted in writing before the original deadline, though approval is at the discretion of the reviewing office.
What happens if I ignore an audit notice entirely?
The IRD can proceed to a best-judgment assessment based on available information, which is generally less favourable than actively participating in the review.
Do I need a lawyer for a Revenue Tribunal appeal?
While not always strictly mandatory, engaging a qualified tax advocate is strongly advisable given the procedural and technical nature of tribunal appeals.
