Introduction

This article, written from a corporate law perspective, explains every step a Nepalese company must take to file taxes in Nepal: registrations (PAN, VAT), what taxes apply (corporate income tax, VAT, withholding taxes/TDS, excise), how to compute tax liability, supporting documentation (audited financials, reconciliation statements), IRD e-filing mechanics, deadlines, penalties, tax audits, and practical compliance checklists.

Part I — Preliminary compliance: registrations every company must complete

1. Obtain Company Registration (OCR)

Before any tax step, the company must be legally incorporated and registered with the Office of the Company Registrar (OCR). This provides the legal identity that will be linked with tax registrations and bank accounts.

2. Obtain PAN (Permanent Account Number) from IRD

Every company must obtain a PAN from the Inland Revenue Department (IRD). PAN is the primary tax identity — without an active business PAN, a company cannot file returns, open formal corporate tax accounts, or process many transactions. The online IRD portal supports PAN registration.

3. VAT registration (if turnover threshold or activity requires)

VAT registration is mandatory where a company’s taxable turnover exceeds the statutory threshold (and for certain specified activities regardless of turnover). VAT registration enables monthly (or, where allowed, quarterly) VAT return filing and input VAT credit. By default, VAT returns are filed monthly within 25 days of the end of the Nepali month. Nil returns are required even if there is no activity.

4. Other registrations (excise, customs, industry-specific)

Depending on business activity — e.g., excisable goods, banking, insurance, telecommunication — additional registrations and licenses (Excise, Customs E-ID, NRB approvals) may be necessary. These affect periodic returns and reporting obligations.

Part II — The principal taxes a company must file and pay

Corporate (Income) Tax — levied on taxable profits of the company; companies must file annual income tax returns and pay taxes as prescribed. Relevant forms include the company Income Tax Return (IRD prescribed form) and supporting schedules (audited financial statements, tax reconciliation).
Value-Added Tax (VAT) — levied on the supply of goods and services (standard rate commonly 13%) and filed monthly (25th of next month) unless IRD permits quarterly filing for small taxpayers. Input VAT credit, zero-rating of exports, and specific exemptions apply.
Withholding Tax / Tax Deducted at Source (TDS) — companies are withholding agents where payments (salary, contractor payments, professional fees, rent, dividends, payments to non-residents) attract withholding obligations. Withholding must be deposited and returns filed (usually monthly) in accordance with IRD rules. Failure to withhold or to deposit invites penalties and personal liability for withholding agents.
Excise Duty / Customs Duties — where applicable, separate filing and payment rules apply for excisable goods and imports.
Advance / Estimated Tax (instalment) — taxpayers required to pay advance tax in instalments when the liability crosses statutory thresholds; estimated tax returns and advance payment schedules are required. Professional briefings for FY 2081/82 highlight these advanced tax rules and filing windows.

Part III — The annual corporate income tax filing process (step-by-step)

Below is a stepwise legal and practical workflow for filing taxes as a company in Nepal.

Step 1 — Ensure PAN is active and linked to the company’s legal identity

Confirm that PAN registration is completed in the IRD system and the PAN is linked to the company’s OCR registration data (name, address, directors). Discrepancies delay filings and refunds.

Step 2 — Maintain statutory books and prepare audited financial statements

Before filing income tax, the company must prepare statutory financial statements — profit & loss, balance sheet, cash flow — in accordance with Nepal Financial Reporting Standards (NFRS) / relevant accounting standards. For most companies, audited financial statements are mandatory and must be attached to the income tax return.

Practical checklist: trial balance → adjustments → tax reconciliation (book profit → taxable income) → depreciation schedules → related party disclosures → tax losses carried forward.

Step 3 — Complete tax reconciliation schedules and compute taxable income

Book profit is adjusted for non-deductible expenses, exempt incomes, provisions, and allowable deductions. Deductible items must adhere strictly to Income Tax Act provisions; for example, certain provisions/reserves may not be deductible until realised. Keep schedules and supporting vouchers for all adjustments (bank statements, invoices).

Step 4 — Verify tax credits: withholding taxes and foreign tax credits

Aggregate withholding taxes (TDS) certificates obtained from agents and reconcile them with the recorded TDS credits. If the company has foreign tax paid, consider double taxation relief as per applicable DTAs (if any) — supporting documentation is essential.

Step 5 — Complete the prescribed IRD Income Tax Return and attachments

The IRD requires a specific return form for companies (check the current IRD form code). Attach audited financials, tax audit report (if required by turnover or legal threshold), reconciliation statements, and withholding tax certificates. Many IRD offices now require e-submission via the IRD Taxpayer Portal, and subsequently, the physical verification or office visit may be necessary depending on the taxpayer’s compliance profile.

Step 6 — Submit the return and pay the tax due

File the return electronically via the IRD e-filing portal (or physically where permitted), and ensure payment of outstanding tax (including any interest/penalties). If the tax is refundable, maintain bank account details linked to PAN for refunds.

Step 7 — Retain records and respond to IRD notices

Keep all records for statutory retention periods (normally several years) and be prepared to respond to IRD information requests or audit notices.

Part IV — VAT filing mechanics (practical law firm guidance)

Registration trigger: exceed the statutory threshold or undertake VATable activity.
Return frequency: by default, monthly, within 25 days from the end of each month. Quarterly filing may be permitted for small businesses with a turnover below the IRD threshold. Nil returns are required when there are no transactions.
Documents & internal controls: maintain VAT invoices for output VAT and supplier invoices for input VAT. Prepare VAT reconciliation schedules monthly to substantiate claims and reduce audit risk.
Common pitfalls: failing to issue standard invoices, not preserving supplier invoices, claiming input VAT without corresponding supplier documentation, and late filing leading to interest and penalties.

Part V — Withholding tax (TDS): the corporate withholding agent’s obligations

When to withhold: salary, contractor payments, professional/technical fees, rent, dividend payments, payments to non-residents — following the prescribed rates and categories.
Deposit & return: withheld amounts must be deposited to the government within stipulated timelines; reconciliation and filing of withholding tax returns is regularly required (monthly/quarterly, depending on IRD rules). Failure to deposit can result in interest, penalties, and director-level scrutiny.

Part VI — Deadlines, payments and common penalties (what directors must be aware of)

Income tax return: annual filing by the company — current IRD practice requires returns within the statutory period after the fiscal year end; for many years, the statutory deadline has been within three months of the fiscal year end (confirm current year deadline on IRD portal). Late filing attracts penalties and interest.
VAT returns: monthly—within 25 days of the month end.
Withholding tax returns/deposits: regular monthly obligations.
Advance tax / Estimated tax instalments: payable by persons who are liable for instalment tax per fiscal year; estimated tax returns and timely deposits are necessary to avoid underpayment penalties.

Note: IRD deadlines and permitted formats may change after each Finance Act; always confirm current year deadlines on the official IRD e-portal before filing. For the most current, authoritative details, consult the IRD SOP and notifications on ird.gov.np.

Part VII — E-filing with the IRD: practical steps and tips

Create a taxpayer login on the IRD Taxpayer Portal (if not already created).
Upload required registrations: PAN number, VAT certificate, and company details.
Prepare digital attachments: audited accounts (PDF), reconciliation schedules (spreadsheet/PDF), and TDS certificates.
Fill the IRD online return modules — income tax, VAT, withholding tax modules — carefully. The portal auto-generates submission numbers and receipts.
Verify & sign the return using authorised signatory credentials (digital signature if required).
Pay tax online through the IRD portal or bank e-channels and retain vouchers for audit.

Pro tips: file a test run early to find portal issues; reconcile TDS credits before filing; submit VAT monthly reconciliations well ahead of the 25-day deadline to manage cash flow.

Part VIII — Documentary evidence and what IRD wants to see in an audit

IRD and auditors typically request:

Audited financial statements and auditors’ report.
Bank statements and reconciliations.
Sales & purchase ledgers, VAT invoices and VAT register.
Fixed asset registers and depreciation schedules.
Withholding tax deposit vouchers and certificates.
Transfer pricing documentation and related party disclosures (for cross-border or related party transactions).
Copies of contracts, invoices and supporting vouchers for major transactions.

Maintain organised, indexed documentation to reduce audit time and dispute risk. A failure to produce documentation often results in IRD adjustments and additional tax assessments.

Part IX — Common legal issues, red flags, and how to avoid them

Mismatch between books and VAT returns — reconcile monthly, and correct promptly.
Failure to deposit withheld taxes — this can result in director liability and fines.
Late filing or non-filing — penalties and interest; repeated non-compliance can escalate to prosecutions in serious cases.
Claiming ineligible expenses — maintain documentary support and legal basis for deductions.
Poor documentation of export sales / zero-rating — maintain export contracts, shipping documents and bank remittance evidence.
Cross-border transactions without transfer pricing — ensure compliance with related party pricing rules and maintain contemporaneous documentation.

Practical defence: implement an internal compliance calendar, a monthly tax close, and an independent monthly review by an external tax adviser.

Part X — Handling disputes, assessments and appeals

If IRD issues an assessment or tax audit report with proposed adjustments:

Promptly evaluate the legal and factual basis for the adjustment with your tax counsel and auditor.
Prepare documentation and a written response within the timelines set by the IRD.
Negotiate when possible (e.g., additional substantiation or alternative settlement).
If unresolved, appeal to the prescribed administrative review body and, subsequently, the appellate tribunal or courts per the tax law procedure. Document timelines carefully — missing appeal windows forfeits rights.

Part XI — Practical compliance checklist for the board / CFO (quarterly & annual)

Quarterly: VAT filing (monthly), TDS deposits & returns, bank reconciliations, payroll tax remittance.
Semi-annual / Annual: audited financials, income tax return and payment, tax reconciliation, advance tax instalments, transfer pricing package if applicable, board review of tax exposures.
Documentation: maintain scanned and indexed copies of all tax vouchers, e-payment receipts, TDS certificates, export documentation and contracts.

Frequently Asked Questions (FAQs)

Q1: What is the deadline to file a company income tax return in Nepal?
A1: Deadlines are set by the Income Tax Act and IRD notifications. Historically, companies file within three months after the fiscal year end, though they confirm the current year deadline on the IRD portal before filing. For the most authoritative procedural details, refer to IRD SOP and current announcements.

Q2: Does every company in Nepal need to register for VAT?
A2: Not every company automatically needs VAT registration — registration is required if turnover exceeds the statutory threshold or for specified VATable activities. Once registered, VAT returns are typically monthly and due by the 25th of the following month.

Q3: What happens if a company fails to deposit withheld tax?
A3: The company (and the responsible officers) may face interest, penalties and potential personal liability. Withholding obligations are taken seriously by IRD — keep deposit vouchers and file returns timely.

Q4: Can tax returns be filed online?
A4: Yes. IRD operates a Taxpayer Portal for online registrations and returns (PAN, VAT, income tax). E-filing and e-payment reduce processing time, but always verify that uploaded attachments meet IRD’s format and signature requirements.

Q5: What documents should be attached to the company income tax return?
A5: Audited financial statements, tax reconciliation, withholding tax certificates, bank statements, fixed asset and depreciation schedule, transfer pricing documentation (if applicable) and any special schedules requested by IRD.
