Independent guide, not an official website
Nepal Docs Guide is not affiliated with the Government of Nepal. This guide helps you prepare, but official portals and offices control final rules, fees, forms, and timelines.
Quick answer
To prepare a revenue-loss complaint, prepare tax, customs, fee or royalty record, official assessment or exemption, payment and account evidence, decision-maker and beneficiary details, confirm the current process with CIAA and the responsible public authority or regional office, complete the official application, and keep the receipt or reference for follow-up.
Eligibility
- People with evidence that a public official caused unlawful loss of government revenue
- Applicants who need to prepare a revenue-loss complaint using matching and genuine records
- An authorized representative only when the responsible authority accepts representation
Required documents checklist
- □ Complainant identity or confidential reporting details appropriate to the complaint
- □ tax, customs, fee or royalty record
- □ official assessment or exemption
- □ payment and account evidence
- □ decision-maker and beneficiary details
- □ Official CIAA online, hotline, email or office complaint reference
- □ Official public-service receipt, transaction, contract or payment record when relevant
- □ Any correction, consent, authorization, or supporting record required for your specific case
Step-by-step process
- Confirm that CIAA and the responsible public authority or regional office is the correct authority for this request.
- Compare names, dates, addresses, registration numbers, account numbers, and other identifiers across tax, customs, fee or royalty record, official assessment or exemption, payment and account evidence, decision-maker and beneficiary details.
- Identify the legal charge and actual payment, show the unsupported waiver or diversion, attach official records, and avoid guessing the total loss.
- Submit through the official portal or office and pay only through the approved channel.
- Save the application number, receipt, uploaded-file copies, and any written instruction for follow-up.
Fees and timelines
- Do not rely on an old fee screenshot or an agent's estimate. Check the latest official notice, citizen charter, portal, or responsible office before paying.
- Processing time depends on document matching, office workload, inspection, examination, technical review, or approval level. Keep the receipt and follow-up reference.
Common mistakes
- Using an old form, notice, fee, or unofficial link
- Submitting incomplete or mismatched tax, customs, fee or royalty record, official assessment or exemption, payment and account evidence, decision-maker and beneficiary details
- Paying an unofficial person or personal account without an official receipt
- Ignoring the difference between a new application, renewal, correction, duplicate, verification, or transfer
- A lawful exemption, appeal or accounting correction is not automatically revenue corruption.
Confirm CIAA jurisdiction and use lawful evidence-preservation methods
