It is one of the most common questions finance teams ask around year-end closing: can the fee paid to the statutory auditor actually be claimed as a deduction against taxable income? The short answer is yes, in almost all ordinary cases — but the fuller answer involves understanding exactly why it qualifies, how other types of assurance fees are treated, what documentation the Inland Revenue Department (IRD) expects to see, and a withholding tax obligation that catches many businesses off guard the first time they engage an external auditor.
Legal Basis: Income Tax Act 2058 Allowable Business Expense Provisions
The Income Tax Act, 2058 (2002) sets out the general principle that expenses incurred wholly and exclusively for the purpose of earning business income are deductible in computing taxable profit, unless specifically excluded or restricted elsewhere in the Act. Professional and consultancy fees — which include statutory audit fees — fall squarely within this general deduction principle, since engaging an auditor is not optional for most registered companies; it is a legal requirement under the Companies Act, 2063, and a cost that is directly and necessarily connected to operating a compliant business. Because the expense arises from a statutory obligation rather than a discretionary choice, there is generally no dispute about whether it relates to the business — the more relevant question in practice is whether it is properly documented and correctly taxed at source.
Statutory Audit Fees as a Deductible Operating Expense
Statutory audit fees — the amount paid to the appointed auditor for conducting the annual audit required under the Companies Act — are treated as a normal deductible operating expense, recorded under professional or legal and audit fees in the profit and loss account. This applies regardless of company size, since every company registered under the Companies Act is required to have its accounts audited annually (with limited exceptions for very small or dormant entities under specific thresholds), making the audit fee a routine and fully allowable cost of doing business, not a discretionary or capital expense that would need to be treated differently.
Tax Treatment of Other Assurance Fees
Beyond the statutory audit, companies increasingly engage professionals for other assurance and advisory work — internal audits, due diligence reviews ahead of a fundraise, forensic investigations following a suspected fraud, or special-purpose audits requested by a lender or regulator. These fees are generally deductible on the same underlying principle, provided they are genuinely incurred for business purposes. A due diligence review commissioned as part of raising equity capital, for instance, is a cost connected to the business's capital-raising activity and is typically deductible as a revenue expense rather than treated as a cost of acquiring a capital asset, though the specific facts and purpose of the engagement can affect this classification. Forensic audit fees incurred to investigate suspected fraud or financial irregularity within the business are similarly deductible, since they relate directly to protecting the company's financial interests. As with any deduction, the key test remains whether the expense was genuinely incurred for the purpose of the business, rather than for a personal or unrelated purpose of the promoters or directors.
Documentation Needed to Support the Deduction
A deduction is only as strong as the paperwork behind it. To support an audit or professional fee deduction during a tax assessment, companies should retain:
- A formal engagement letter or appointment confirmation from the auditor, specifying the scope and fee for the assignment.
- A properly issued tax invoice or bill from the auditor, showing the fee amount, VAT (if applicable), and the auditor's PAN details.
- Proof of payment — bank transfer records or payment vouchers — matching the invoiced amount, net of any TDS withheld.
- Evidence of TDS deduction and deposit, including the TDS certificate issued to the auditor and the corresponding e-TDS filing with the IRD.
Missing or informal documentation — for example, an audit fee paid in cash without a proper invoice — is one of the more common reasons a claimed deduction gets challenged or disallowed during a tax assessment.
TDS Obligations on Payments to Auditors
Here is where many businesses trip up, particularly when engaging an auditor or professional service provider for the first time: payments for professional and consultancy services, including audit fees, are subject to tax deduction at source (TDS) under the Income Tax Act. The company paying the fee is required to withhold the applicable percentage from the payment due to the auditor, deposit that amount with the IRD within the prescribed deadline, and issue a TDS certificate to the auditor reflecting the amount withheld. Failing to withhold TDS correctly does not just create a compliance issue for the payer — it can also affect whether the underlying expense is fully allowed as a deduction, since the IRD may disallow expenses where the corresponding TDS obligation was not properly discharged. Companies should confirm the correct withholding rate applicable to professional fees at the time of payment, since rates and thresholds are set out in the Finance Act provisions applicable for each fiscal year and can be revised from one year to the next.
Conclusion
Statutory audit fees, and most other genuine assurance and advisory fees connected to the business, are deductible business expenses under Nepal's Income Tax Act — the deduction itself is rarely in question. What determines whether that deduction survives scrutiny is the quality of the supporting documentation and whether TDS was correctly withheld and deposited at the time of payment. Getting both of these right at the time the fee is paid, rather than trying to reconstruct them at year-end, is the simplest way to make sure a routine, legitimate expense doesn't turn into an avoidable dispute during a tax assessment.
