Corporate tax filing in Nepal isn't a single event — it's a chain of dependent deadlines starting with a statutory audit and ending with a reconciled return at the IRD. Miss the audit, and you can't file the return on time; miss the return, and interest starts compounding immediately. Here's the full picture for finance teams and company owners: which forms apply, how accounting profit becomes taxable income, and where companies most often trip up.
Applicable Return Forms and Filing Categories by Company Size/Type
Companies and other business entities file their annual income tax return using the corporate return (commonly referenced as Form 02 in IRD's return categorisation), distinct from the individual return (Form 01) and the presumptive/turnover-based small-taxpayer forms (D-01/D-02) covered in our small-business guides. Every registered company files this return annually regardless of profitability — a loss-making or dormant company still owes a nil or loss return; there is no exemption for having no activity in a given year. The standard corporate tax rate is 25% for most companies, rising to 30% for banks, financial institutions, insurance companies, and telecom operators, and dropping to roughly 20% for special industries such as manufacturing and export-oriented businesses, with further sectoral concessions available for hydropower and infrastructure companies.
Audited Financial Statement Requirement as a Filing Prerequisite
A statutory audit is mandatory for every incorporated company in Nepal — there is no revenue or size threshold that exempts a small or newly registered company from this requirement, regardless of what the company's own articles might suggest. The tax audit report, prepared by a licensed auditor, must accompany the corporate income tax return when it is filed with the IRD. Separately, under the Companies Act 2063, every company must hold an Annual General Meeting within six months of the fiscal year end and submit the AGM return — including audited financial statements and the directors' and auditors' reports — to the Office of the Company Registrar (OCR). In practice, this means the audit needs to be substantially complete well before the tax filing deadline, not treated as a parallel, lower-priority task.
Tax Reconciliation — Moving From Accounting Profit to Taxable Income
Your audited financial statements report accounting profit under prevailing accounting standards, but the IRD taxes a different, adjusted figure. The reconciliation generally follows this pattern: start with net profit per the audited financial statements, add back expenses that are not tax-deductible under the Income Tax Act, deduct income that is tax-exempt or already taxed at source as a final withholding, apply depreciation calculated under the IRD's own prescribed rates and pooling method (rather than your book depreciation), and adjust for any tax losses carried forward from prior years within the permitted carry-forward period. The resulting figure — not the audited profit itself — is what the 25% (or applicable) corporate rate is applied to.
Common Disallowed Expenses Under the Income Tax Act
Certain expenses that reduce accounting profit are added back for tax purposes because the Income Tax Act doesn't recognise them as deductible business costs. Common categories include: entertainment and hospitality expenses beyond prescribed limits, donations to entities not approved by IRD as tax-exempt, general or unspecified provisions (such as a blanket provision for doubtful debts that hasn't met the specific write-off criteria), fines and penalties paid to any government authority, personal or non-business expenses run through company accounts, and interest or expenses related to income that is itself exempt from tax. Getting this add-back list wrong — either missing a disallowed item or over-adding a genuinely deductible one — is one of the most common sources of disputes during an IRD assessment.
Depreciation Under Tax Law vs Accounting Depreciation — The Reconciliation
Book depreciation, calculated under accounting standards using straight-line or reducing-balance methods over the asset's useful economic life, almost never matches the depreciation the IRD allows. The Income Tax Act groups depreciable assets into prescribed pools (by asset class — buildings, vehicles, computers, plant and machinery, and so on) and applies a fixed statutory rate to the pooled written-down value each year, regardless of the specific useful life your accountant assigned in the books. The reconciliation adds back the full book depreciation charge and then deducts the tax-allowed depreciation instead, which can create a materially different taxable income figure — particularly in the early years of holding a new, large asset, where tax depreciation is often faster than book depreciation.
Advance Tax and TDS Credit Adjustment at Year-End
By the time you file the final return, your company has typically already paid tax through two channels during the year: the three cumulative advance tax instalments (40%/70%/100% of estimated liability, due Poush, Chaitra, and Ashadh end) and any TDS withheld by customers or clients on payments made to you. Both are credited against your final computed tax liability on the annual return. If the combined advance tax and TDS credits exceed your final liability, the excess is refundable or carried forward; if they fall short, the balance is due with the return itself, along with any applicable interest if the advance tax instalments individually fell short of the required 90% cumulative threshold.
Filing Deadline, Extension Process, and Late Filing Penalties
The final corporate income tax return, with the tax audit report attached, is due within three months of the fiscal year end — by Ashwin end (approximately mid-October). A company that genuinely cannot meet this deadline can request an extension from the IRD before the original due date lapses; extensions are discretionary and should be sought with a clear reason, not assumed automatically. Late submission of the tax audit report specifically can attract a separate penalty (commonly cited around NPR 1,000 per month of delay), on top of the standard late-filing fee and 15% annual interest on any unpaid tax balance that applies more broadly under the Income Tax Act.
FAQs — Filing for a Loss-Making Company, Carry-Forward of Losses
Q: Does a company that made a loss still need to file a return?
Yes. A loss return must still be filed by the standard deadline, complete with audited financial statements. Filing is not conditional on having taxable profit for the year.
Q: Can a business tax loss be carried forward to offset future profit?
Yes, tax losses can generally be carried forward and set off against taxable profit in future years, subject to a maximum carry-forward period (commonly cited as up to 7 years) and specific rules that can vary by industry or in the case of ownership changes.
Q: What happens if a company simply stops operating without formally filing?
The filing obligation and any associated penalties continue to accrue until the company is formally dissolved through the proper legal process at the OCR and IRD, including obtaining tax clearance. Simply going inactive does not end the compliance obligation.
Note: Deadlines, penalty amounts, and depreciation pooling rules should be confirmed against the current Finance Act and Income Tax Rules, as some figures are adjusted periodically. This guide is general information, not tax advice for your specific company.
