Tax evasion: a separate investigation track under the Revenue Leakage Act alongside the powers in each tax law

Possible conflict between lawsMedium confidenceEnacted ActReform recommendation

The Revenue Leakage (Investigation and Control) Act 2052 makes evasion of any tax an offence and gives the Department of Revenue Investigation power to investigate it. The Income Tax, VAT, Excise and Customs Acts also give the tax and customs offices power to search, recover, stop travel, prosecute and (for customs) decide cases. The High-Level Economic Reform Suggestion Commission said this creates duplicate investigation and recommended repealing the 2052 Act. The Customs Act 2082, passed later, still refers to officers acting under the revenue leakage law.

Laws and sections involved

राजस्व चुहावट (अनुसन्धान तथा नियन्त्रण) ऐन, २०५२ s.2(क) (definition of revenue); s.4 (acts deemed revenue leakage); s.6(1) (Department's jurisdiction)
Our paraphrase: "revenue" covers customs duty, excise, income tax, VAT and other federal, provincial and local taxes and non-tax charges (s.2(क)); filing false accounts or returns to pay less or no revenue, hiding income, and similar acts are revenue leakage (s.4); investigation of revenue leakage offences "shall be done by the Department" (s.6(1)).

The apparent issue

The same suspected evasion can fall within the Revenue Leakage Act, investigated by the Department of Revenue Investigation, and within the tax or customs Act, administered by the Inland Revenue Department or Customs. The texts read do not set out which body leads, how a case moves from one to the other, or how duplicate inquiries into the same transaction are avoided.

Evidence

The Commission said the evasion the 2052 Act defines is also covered in each tax and non-tax law, and those laws give their own bodies power to investigate and act. It listed the Income Tax Act powers in ss.82, 104–106, 111 and 135, said the VAT and Excise Acts give even wider powers, and noted the Customs Act lets customs officers investigate and impose up to one year's imprisonment. High-Level Economic Reform Suggestion Commission Chapter on institutional, policy and legal environment, paras 12–14, printed pp.86–87 (PDF pp.153–154)
The Commission concluded that the 2052 Act creates a double system of investigation and action, that this has been used to intimidate businesses, that the Department has at times entered matters a specialist body should handle and filed wrong cases, and that vehicles carrying goods with certified stock-transfer documents have been stopped arbitrarily on highways. It recommended repealing the Act. High-Level Economic Reform Suggestion Commission Para 14, printed p.87 (PDF p.154); recommendation 33(ज), printed p.93 (PDF p.160); executive summary 24(ज), printed p.XIV (PDF p.17)
The Commission's report is dated 2081 Chaitra 29. The Customs Act 2082, published later (2082/05/22), expressly recognises officers authorised under the revenue leakage law to inspect and seize sealed customs goods (s.29), and the Revenue Leakage Act itself was amended again in 2082 (2082/04/14). The texts read therefore show the dual system was kept after the recommendation. Nepal Law Commission Customs Act s.29, PDF pp.17–18; Revenue Leakage Act title page, PDF p.1

Possible readings

Reading 1 (the Commission's view): the tax Acts already provide complete investigation and enforcement powers, so the 2052 Act duplicates them, raises compliance costs and creates room for repeated or misdirected cases; it should be repealed.
Reading 2: the 2052 Act targets organised or cross-tax evasion (false declarations, collusion with staff, hidden income across several taxes) that a single tax office may not see; the overlap is deliberate, and Parliament reaffirmed it in the Customs Act 2082. The problem, if any, is coordination, not conflict.
Reading 3: the general rule that a person is punished only once for one offence (Nepal Law Interpretation Act s.25) limits double punishment, but does not by itself prevent two investigations of the same facts; whether a second investigation is lawful once one body has acted is a separate question.

Why it matters in practice

If the overlap is uncoordinated, a business could face more than one inquiry into the same transaction, with higher compliance costs and inconsistent outcomes; if the overlap is removed without a replacement, investigation of complex evasion that crosses several taxes could become weaker.

Hypothetical example

Hypothetical: an importer under-declares the value of goods. Customs opens a case under the Customs Act and the customs officer decides it. Months later the Department of Revenue Investigation opens an inquiry under the Revenue Leakage Act into the same shipments and the importer's income tax returns. The importer is unsure whether the first decision ends the matter.

Possible improvements and trade-offs

Repeal the Revenue Leakage Act 2052 and leave investigation to the body administering each tax law (the Commission's recommendation).
Removes duplication; but would require deciding what happens to pending cases, to the Department of Revenue Investigation and to the provision the Customs Act 2082 now makes for its officers, and may leave cross-tax and collusion cases with no single investigator.
Keep the Act but add a lead-agency and referral rule: the Department investigates only above a threshold, across several taxes, or on referral, and must not reopen a matter already decided under a tax Act.
Keeps specialist capacity and reduces duplication; needs careful drafting of thresholds and of the finality rule, and data sharing between bodies.
No change to the Acts; address the problem through an inter-agency protocol and published statistics on overlapping cases.
Quick and flexible; a protocol cannot limit powers an Act grants, so businesses would have no enforceable protection.

Questions for legal review

Where the same conduct is an offence under the Revenue Leakage Act and under a tax or customs Act, which body has priority, and does a final decision under one Act bar proceedings under the other?
How does s.25 of the Nepal Law Interpretation Act (one punishment for an offence under two Acts) apply to administrative penalties and to investigation, as distinct from punishment?
What would repeal mean for s.29 of the Customs Act 2082 and for cases pending under the 2052 Act?

Research status

Researched: 2026-10-12
Confidence: Medium confidence — The overlapping powers were read in the official texts and a government-appointed commission states the duplication directly. Confidence is not high because the Commission's account of harm is not quantified in the pages read, and the later Customs Act suggests Parliament may regard the overlap as intended.
Review: Not yet reviewed by a qualified lawyer.

Still unresolved

No data were found on how many cases are investigated under both regimes or on outcomes.
The VAT and Excise Acts' investigation provisions were not read section by section for this note.
The Government's response to the Commission's repeal recommendation was not found.
