Pakistan Income Tax Return Guide (TY2026)
8/30/2026

The financial landscape for businesses in Pakistan has undergone a significant transformation with the promulgation of the Finance Act, 2025. Effective from July 1, 2025, this Act introduces crucial amendments to the Income Tax Ordinance, 2001, particularly concerning disallowance provisions that directly impact the computation of taxable income. At R.M. Tahir & Co. Chartered Accountants, we are committed to ensuring our clients are fully informed and prepared to navigate these changes. This comprehensive analysis clarifies the statutory foundations, operational implications, and necessary compliance measures stemming from these new rules.
The Finance Act, 2025, has meticulously amended key sections of the Income Tax Ordinance, 2001, to introduce stringent disallowance clauses aimed at enhancing documentation and formalizing the economy.
1.Disallowance of Cash Sales Exceeding Rs. 200,000
A pivotal amendment has been inserted into Section 24 (Deductions not Allowed) of the Income Tax Ordinance, 2001. This newly added sub-section explicitly states:
"Where any sale proceeds are received in cash and the amount of such cash sale exceeds two hundred thousand rupees in respect of a single transaction or per invoice, fifty percent of the expenditure attributable to such sale shall be disallowed for the purposes of computing income under the head 'Income from Business'."
This provision is clear: if your business receives cash for a single transaction or per invoice that exceeds the Rs. 200,000 threshold, a substantial 50% of the expenditure directly linked to that specific sale will be deemed non-deductible for tax purposes. It is crucial to note that while recent Federal Board of Revenue (FBR) notices have alluded to an effective tax disallowance of 20.5%, this appears to be an interpretative derivation, possibly factoring in minimum tax or withholding impacts. The explicit legal stipulation, as per the Finance Act, unequivocally maintains the disallowance rate at 50% of the corresponding expenditure. Businesses must strictly adhere to the 50% statutory rate when planning their compliance strategies.
2. Disallowance of Payments to Non-NTN Holders
In a further step towards comprehensive documentation, a new clause has been incorporated into Section 21 (Deductions Not Allowed) of the Ordinance, targeting transactions with unregistered entities. The provision mandates:
"Any expenditure incurred by a taxpayer in respect of a payment made to a person not bearing a valid National Tax Number (NTN) shall be subject to disallowance to the extent of ten percent of such expenditure."
This implies that any expense incurred and paid to an individual or entity that does not possess a valid National Tax Number (NTN) will be subject to a 10% disallowance for tax deduction purposes. This measure strongly aligns with the FBR's intensified enforcement efforts, where invoices or transactions lacking proper NTN documentation are increasingly being refused recognition for tax credits or adjustments. The intent is to discourage informal transactions and bring more entities into the tax net.
These new provisions carry significant operational ramifications that demand immediate attention from all taxpayers:
The introduction of these provisions has naturally elicited a diverse range of reactions across commercial sectors:
To safeguard your business against potential disallowances and ensure seamless compliance, R.M. Tahir & Co. strongly recommends the following immediate actions:
The measures introduced through the Finance Act, 2025, are legally anchored and represent a firm legislative intent to formalize economic activities and enhance tax compliance. While the legal text regarding the disallowance percentages is clear, practical application, particularly concerning implementation timelines and audit methodologies, will undoubtedly benefit from further procedural guidance.
All tax payers are strongly advised to adopt a conservative compliance posture. This involves a proactive avoidance of high-value cash transactions and a concerted effort to engage exclusively with NTN-compliant parties. Such a disciplined approach is paramount to safeguarding against potential disallowance of deductions and mitigating resultant tax exposure.
