Income Tax
Allowable Business Expenses in Nepal
Applicable Income Year: FY 2083/84
Primary law: Income Tax Act, 2058, including Finance Act 2083 amendments Key provisions: Sections 12–20 and related provisions
A business expense is not automatically tax deductible simply because it is recorded in the profit and loss account.
For income-tax purposes, the expenditure must satisfy the applicable provisions of the Income Tax Act.
The starting test is whether the expenditure was properly incurred in deriving taxable business or investment income, followed by the specific rules governing interest, stock, repairs, research, depreciation, losses and prohibited expenditure.
1. Test whether an expense is deductible
CMA Seven-Point Deductibility Test
Before claiming an expense, ask:
1. Was the expense actually incurred?
There should be a genuine liability or payment.
2. Does it relate to the relevant income year?
Timing rules must be considered.
3. Was it incurred to derive taxable business or investment income?
A private expense does not become deductible merely because a business paid it.
4. Is it revenue or capital in nature?
Capital expenditure normally requires separate statutory treatment.
5. Is there a specific provision dealing with the expenditure?
Examples:
interest;
trading stock;
repairs;
pollution control;
research and development;
depreciation;
losses.
6. Is it prohibited under section 21?
Even commercially reasonable expenditure can be specifically disallowed.
7. Is adequate evidence available?
Invoices, PAN information, bank payment, TDS compliance and other records may be necessary.
Common Categories of Potentially Deductible Expenditure
Subject to statutory requirements, business expenses may include items such as:
employee remuneration;
office rent;
utilities;
telephone/internet;
professional fees;
business travel;
advertising;
insurance;
repairs;
bank charges;
interest;
software/subscriptions;
business supplies;
trading stock costs;
tax depreciation;
qualifying research and development;
qualifying pollution-control expenditure;
bad debts where statutory conditions are satisfied;
other expenditure directly connected with deriving taxable business income.
Each category must still pass the statutory test.
2. Payroll, rent and professional costs
Employee Costs
Business-related employee remuneration may generally be deductible where:
genuinely incurred;
supported by payroll/employment records;
PAN-related requirements are satisfied;
TDS has been correctly handled;
the payment is not personal expenditure disguised as salary.
Maintain:
employment agreement;
payroll;
attendance where relevant;
bank/payment proof;
TDS record;
SSF/PF/CIT records where applicable.
Rent
Business-premises rent can generally form part of deductible expenditure where genuinely incurred for business purposes.
However:
personal residence portions should be separated;
related-party rent should be commercially supportable;
applicable TDS should be deducted and deposited;
agreements and payment evidence should be retained.
Professional and Consultancy Fees
Examples:
audit fees;
legal fees;
accounting fees;
engineering fees;
management consultancy;
IT consultancy.
Deductibility should be tested together with: business purpose + invoice + PAN/VAT status + TDS compliance + payment evidence.
3. Interest, stock, repairs and special deductions
Interest Expense
Interest requires separate analysis under section 14.
Questions include:
Was borrowing used to generate taxable income?
Is part of the borrowing personal?
Is the borrowing related-party?
Is it cross-border?
Does transfer pricing apply?
Does withholding apply?
Is any part capitalised or otherwise governed by a special rule?
Therefore:
Loan exists → interest deductible
is not a safe rule.
Trading Stock
Section 15 contains specific rules for trading stock.
Tax computation may require analysis of:
opening stock;
purchases;
production costs;
closing stock;
valuation;
damaged/obsolete stock;
stock disposals.
Inventory accounting in financial statements and the tax computation should be reconciled.
Repairs vs Improvements
Section 16 requires a distinction between repairs and capital improvements.
Repair
Generally restores or maintains an asset.
Improvement
May increase capacity, extend useful life, substantially alter the asset or otherwise create capital value.
Example: Replacing a small damaged component may be a repair.
Constructing an additional storey on a building is unlikely to be an ordinary repair.
The tax and accounting treatment should both be reviewed.
Pollution-Control Expenditure
Qualifying pollution-control expenditure is dealt with under its own statutory provision.
This can be particularly relevant to:
manufacturing;
hospitals;
industrial facilities;
environmentally sensitive businesses.
It should not simply be added to ordinary operating expenditure without checking the statutory limits.
Research and Development
Section 18 provides special treatment for qualifying research and development expenditure related to business development or improvement of production/processes.
Acquisition of certain assets/property is subject to separate treatment.
For software development, product development, technical testing and process improvement, examine the nature of the expenditure and the statutory distinction between qualifying research expenditure and acquired assets.
software development;
product development;
technical testing;
process improvement;
internally developed intangibles.
Tax Depreciation
Accounting depreciation should normally be added back in preparing the tax reconciliation, with the appropriate tax depreciation deduction calculated separately under section 19 and Schedule 2.
Therefore: Accounting depreciation
≠
Tax depreciation
The tax computation should use the relevant tax asset group, tax pool and prescribed rate.
Business Losses
Section 20 allows eligible losses to be carried and utilised subject to statutory limits.
The current framework distinguishes, among other matters:
ordinary business losses;
investment losses;
foreign-source losses;
losses connected with exempt income;
specified infrastructure/project losses;
change-in-control restrictions.
A loss should therefore be tracked by source and character, not merely as one accumulated balance.
4. FY 2083/84 donation, CSR and payment changes
Donation Deduction — FY 2083/84
Finance Act 2083 increases the monetary ceiling for qualifying donations.
The current working limit is the lower of: NPR 300,000
or
5% of adjusted taxable income
The limit applies only to a qualifying donation under the statutory recipient and other conditions.
A donation should not be claimed merely because the business made a charitable payment. The recipient and statutory conditions must qualify.
CSR Expenditure — New FY 2083/84 Provision
Finance Act 2083 introduces a specific deduction for qualifying Corporate Social Responsibility expenditure required under prevailing law.
The deduction is subject to a ceiling of 1% of total taxable income under the new provision.
This should be distinguished from:
ordinary donation;
advertising/sponsorship;
voluntary charity;
sector-specific CSR obligations.
The business must first determine whether the expenditure qualifies under the applicable CSR law.
Cash Payment Restriction — Important FY 2083/84 Change
Finance Act 2083 significantly tightens the section 21 cash-payment restriction.
The current-year change: Old general threshold: NPR 50,000
New threshold: NPR 25,000 per transaction and the previous turnover-based limitation has been removed, making the rule applicable more broadly.
Example
Business purchases office equipment costing NPR 40,000 and pays entirely in cash.
The expenditure must be reviewed under section 21 rather than assumed deductible.
Exceptions
The Act contains specified exceptions, historically including categories such as certain payments to government/government-owned institutions, specified agricultural producers, locations without banking facilities and mandatory cash situations.
The current statutory exception list should be verified for FY 2083/84 before relying on an exception.
Share and Debenture Issue Expenses — FY 2083/84
Finance Act 2083 changes the section 21 treatment of expenditure incurred in issuing shares or debentures.
The Finance Act 2083 amendment removes share and debenture issue costs from the specified capital-expenditure definition. The remaining deduction conditions still apply.
Apply the ordinary deduction tests before concluding that a particular issue cost is deductible.
Therefore the safer formulation is:
Share/debenture issue expenditure is no longer automatically excluded solely under the former capital-expense treatment, but its actual deductibility must still satisfy the remaining Income Tax Act requirements.
5. Documents and a tax-adjustment example
Documentation Checklist
For every material deduction:
Invoice/bill obtained
Supplier identity verified
PAN included where required
VAT invoice obtained where applicable
Business purpose documented
Payment evidence retained
Cash-payment restriction checked
TDS requirement checked
Capital/revenue treatment checked
Related-party relationship checked
Contract/agreement retained
Expense recorded in correct FY
Tax adjustment documented
Supporting evidence retained for audit
Example — Accounting-to-Tax Adjustment
Accounting profit before tax: NPR 5,000,000
Included in accounting expenses:
accounting depreciation: NPR 600,000
personal director expense: NPR 150,000
income-tax penalty: NPR 50,000
Tax depreciation allowable: NPR 800,000
Simplified reconciliation: Accounting profit: NPR 5,000,000
accounting depreciation: NPR 600,000
personal expense: NPR 150,000
non-deductible penalty: NPR 50,000
− tax depreciation: NPR 800,000
= Indicative taxable income: NPR 5,000,000
The example illustrates why merely reading the accounting profit is insufficient.

Further guidance and practical checks
Tax deductibility should be established from the Income Tax Act rather than the accounting ledger alone. Evidence, payment method, withholding compliance and the purpose of expenditure should be reviewed together.
