Tax & Customs Lawyers in Karachi
Income tax, sales tax and customs disputes before FBR and appellate tribunals. Irfan Mir Halepota & Associates represents clients in this area before the relevant Karachi courts and tribunals.

Tax matters in Pakistan move through a defined appellate chain, and each stage — audit, assessment, first appeal, tribunal — narrows the room to raise new arguments. We advise on structuring to avoid disputes in the first place, and represent clients through contested assessments, show-cause notices and customs valuation disagreements when they arise.
What this covers
- Income tax and sales tax assessments and audits
- Appeals before the Commissioner (Appeals) and Appellate Tribunal Inland Revenue
- Customs valuation, classification and duty disputes
- Show-cause notice responses and penalty proceedings
- Tax planning and compliance advisory
- Reference applications before the High Court
Where we appear
- Federal Board of Revenue (FBR)
- Appellate Tribunal Inland Revenue
- Customs Appellate Tribunal
- High Court of Sindh (Tax References)
- Supreme Court of Pakistan (further appeal from tax references)
- Federal Constitutional Court of Pakistan (constitutional questions on tax vires)
Forum selection and limitation periods are often decided in the first conversation about a matter — the earlier we're involved, the more options remain open.
Reading an FBR notice correctly
The section cited on a notice determines what is alleged, how long you have, and what a good reply looks like. The provisions most often encountered under the Income Tax Ordinance, 2001:
- Section 114 — notice to file a return, typically with a short deadline
- Section 176 — demand for documents or information
- Section 177 / 214C — selection for audit
- Section 122 — amendment of assessment, the notice most often requiring professional handling
- Section 111 — unexplained income or assets, where the burden of explanation falls on the taxpayer
- Section 161 — withholding tax audit
- Section 138 — recovery, by which stage assessment is behind you
Parallel provisions apply under the Sales Tax Act, 1990 and the Federal Excise Act, 2005. Before responding to anything, verify the notice appears in your IRIS inbox with a matching reference — fraudulent notices circulate.
Deadlines that bind the department, not only the taxpayer
A point most taxpayers never learn. The Finance Act, 2021 requires proceedings under Section 122 to be concluded within 120 days of the show-cause notice, extendable by the Commissioner for up to a further 90 days only for reasons recorded in writing, for notices issued after 1 July 2021. The Ordinance separately prescribes a five-year outer limit for amendment of assessment.
Where a notice or order falls outside these limits, that is a substantive ground of challenge independent of the merits of the tax question. Checking the dates is worth doing before arguing about figures. See our guide to responding to an FBR show-cause notice.
The appeal chain, and why the first stage decides most cases
- Commissioner (Appeals) — a full appeal on both facts and law. This is the last stage at which factual material can be introduced freely.
- Appellate Tribunal Inland Revenue — independent of the department, and the final authority on questions of fact.
- High Court — by reference on a question of law only, not a rehearing of the assessment.
- Supreme Court of Pakistan in appropriate cases; constitutional challenges to a provision's vires now fall to the Federal Constitutional Court.
Read from the top down, the strategy is obvious: the entire factual case must be built and evidenced at the assessment and first-appeal stage, because nothing above the Tribunal will reweigh it. Our page on the tax assessment appeal route sets this out in full.
For the later stages, see our guides to filing a tax reference in the High Court under section 133 and taking a tax case to the Supreme Court of Pakistan. Super tax disputes after the Federal Constitutional Court's January 2026 ruling are covered in super tax under section 4C.
One trap worth naming: filing an appeal does not automatically stay recovery. A stay must be separately applied for and granted, which is why a recovery-focused application often needs to run in parallel with the substantive appeal.
Customs valuation and classification
Import disputes usually turn on valuation or tariff classification. Section 25 of the Customs Act, 1969 prescribes six valuation methods that must be applied in a mandatory sequence beginning with declared transaction value — customs cannot simply reject an invoice and substitute a higher figure without recording why each intervening method could not be applied. Where a step was skipped without justification, that is a ground of challenge in itself.
Where a Valuation Ruling under Section 25A covers the goods, the Ruling itself must be addressed — a review petition lies to the Director General under Section 25D within a short window. Section 81 provisional assessment allows goods to be released against security while the dispute proceeds, which stops demurrage accruing. See our page on customs valuation disputes.
Structuring to avoid disputes
A significant share of tax litigation traces to arrangements that were never documented adequately at the time — intra-group transactions without agreements, payments without withholding, or asset acquisitions the wealth statement cannot reconcile. Advice at the transaction stage is materially cheaper than an assessment appeal three years later.
Tax litigation by industry sector
Tax disputes turn on sector-specific facts as often as on general principle. The notes below set out where disputes recur in each industry we act for, and our reported experience before the High Court of Sindh, compiled from publicly available case records.
Sugar mills & agro-industry
Reported experience: 108 matters before the High Court of Sindh between 2009 and 2025, across 39 corporate groups (client names are not published).
Where sugar and agro-industry tax disputes concentrate
Sugar mills face a particular concentration of disputes around federal excise duty on sugar, which has been adjusted by rate and by Finance Act more frequently than most other excisable goods, and sales tax on agricultural inputs and outputs, where exemptions for specific agricultural products are periodically narrowed or withdrawn. Provincial agricultural income tax questions add a further layer distinct from federal income tax assessment, since agricultural income is taxed provincially under separate legislation rather than under the federal Income Tax Ordinance.
Seasonal cash flow and assessment timing
The sugar crushing season creates a concentrated period of input purchases, output sales and refund claims within a short window each year, which in turn means assessment disputes for this sector often turn on documentation and timing evidence specific to the crushing season rather than on year-round trading patterns — a distinction that matters when assembling the evidentiary record for an appeal.
Textile & manufacturing
Reported experience: 49 matters before the High Court of Sindh between 2006 and 2024, across 31 corporate groups (client names are not published).
Why textile tax disputes are so frequent — a regulatory history of reversals
Much of the litigation in this sector traces back to a single, repeatedly reversed policy: sales tax zero-rating for the five major export-oriented sectors (textile, leather, carpets, sports goods and surgical goods). The regime has changed direction four times since it was first introduced:
- 2005 — zero-rating introduced by the Finance Act, 2005 to stimulate export-oriented sectors
- 2011 — formalised at a reduced 5% rate under SRO 1125(I)/2011, the order that became the industry's shorthand reference point for over a decade
- 2013 — zero-rating withdrawn without the promised expedited refund system, creating a liquidity crunch for exporters
- 2016 — restored
- 2019 — abolished again in the federal budget, restoring standard-rate sales tax (raised progressively toward 17%) on the sector on the stated ground of preventing revenue leakage
- 2024–25 — a new framework introduced under the Export-Oriented Sectors (Zero-Rating) Rules via SRO 209(I)/2024, again altering the compliance and refund mechanics
Each reversal has generated its own wave of assessment disputes, refund claims and reference applications, because businesses that structured pricing, contracts and input-tax planning around one regime found themselves reassessed under the next. A tax dispute in this sector is frequently, at its root, an argument about which version of the SRO regime applied at the time the relevant supply was made — which makes the exact date of the transaction, not just its nature, central to the case.
Where the disputes concentrate
The recurring flashpoints are input tax refund delays and disputed refund claims following withdrawal of zero-rating, further tax under Section 3(1A) of the Sales Tax Act, 1990 on supplies to unregistered persons — an area FBR has taken restrictive positions on even within nominally zero-rated categories — and classification disputes over which specific products fall within a given SRO's schedule of covered items.
Oil, gas & energy
Reported experience: 65 matters before the High Court of Sindh between 2006 and 2025, across 25 corporate groups (client names are not published).
Where oil, gas and energy tax disputes concentrate
This sector's litigation typically arises from three recurring sources. Petroleum levy and royalty disputes sit alongside, and are frequently confused with, ordinary income and sales tax assessments — the two regimes are governed by different statutes and require separate analysis even where they arise from the same underlying transaction. Withholding tax on payments to exploration and production contractors, often foreign entities operating under production-sharing agreements, raises questions about which treaty provisions and which domestic withholding rate actually apply. And sales tax on natural gas and petroleum products is subject to sector-specific rates and exemptions that shift with Finance Act amendments more frequently than the general rate structure, making the applicable rate at the date of supply — not the date of dispute — the point that actually needs establishing.
Constitutional petitions in this sector
Energy sector tax matters frequently raise constitutional questions distinct from ordinary tax appeals — particularly where a levy is challenged as being outside the legislature's competence, or where retrospective application of a rate change is contested. These proceed through constitutional petition before the High Court of Sindh rather than through the ordinary tax appeal chain, and the two should not be conflated when deciding where to file.
FMCG & consumer goods
Reported experience: 51 matters before the High Court of Sindh between 2007 and 2026, across 28 corporate groups (client names are not published).
Where FMCG and consumer goods tax disputes concentrate
Fast-moving consumer goods companies face recurring disputes over federal excise duty on specific product categories, sales tax classification disputes over which rate schedule a product falls into — a beverage, confectionery or personal care classification often carries a materially different rate than an adjacent category — and withholding tax on distributor and retailer payments, an area FBR has extended documentation and withholding measures into over successive Finance Acts, most recently reaching pharmaceuticals, edible oil, auto-parts and several other sectors previously outside the regime.
Transfer pricing exposure for multinational FMCG groups
Where an FMCG business operates as part of a multinational group, transactions with related foreign entities — royalty payments, management fees, intra-group purchases — attract transfer pricing scrutiny under the Income Tax Ordinance, 2001. This is a distinct and increasingly active area of assessment separate from ordinary sales and excise tax questions, and it requires its own documentation and defence strategy.
Pharmaceutical & healthcare
Reported experience: 18 matters before the High Court of Sindh between 2014 and 2026, across 10 corporate groups (client names are not published).
Where pharmaceutical tax disputes actually arise
The recurring flashpoint is classification — whether a product qualifies for the reduced sales tax rate available to registered drugs, or is instead taxed at the standard rate because of how it is categorised. Entry No. 81 of Table-1 of the Eighth Schedule to the Sales Tax Act, 1990 grants a reduced rate specifically to "substances registered as drugs under the Drugs Act, 1976." The difficulty is that DRAP itself classifies many therapeutic products differently — as a medical device under the Medical Devices Rules, 2017 made under the DRAP Act, 2012, rather than as a registered drug — and DRAP's own classifications have shifted by SRO more than once for the same product category.
This is not a hypothetical problem. In a recent matter before the High Court of Sindh, a petitioner's sutures were excluded from the definition of "drug" by SRO 824(I)/2018, then brought within the Medical Devices Rules regime by SRO 526(I)/2021 — leaving the importer's sales tax treatment dependent on which regulatory characterisation applied at the relevant time (citing International (Pvt.) Ltd. v. Pakistan, 2024 PTD 1121). Where DRAP's own certificate categorises a product as a medical device, FBR has taken the position that the reduced Entry 81 rate for registered drugs does not apply — a dispute that sits squarely at the intersection of regulatory and tax law.
Withholding tax on distributors
Pharmaceutical distributors are subject to withholding tax under Section 153 of the Income Tax Ordinance, 2001, and the applicable rate has moved with successive Finance Acts — a reminder that the current rate should always be confirmed against the year in question rather than assumed static. FBR has separately clarified, in response to industry concern, that documentation and withholding measures on trader income do not alter the maximum prices DRAP sets for medicines, since drug pricing and income tax withholding are governed by entirely separate regulatory regimes.
Why sector-specific advice matters here
A generic tax dispute approach misses the point in this sector: the tax question is frequently downstream of a DRAP regulatory determination, so the strongest argument in an FBR reference is often built on the regulatory classification itself — the DRAP certificate, the applicable SRO, and the Schedule under which a product was registered — rather than on tax argument alone.
Banking, insurance & financial services
Reported experience: 81 matters before the High Court of Sindh between 1998 and 2024, across 23 corporate groups (client names are not published).
Automobile, steel & engineering
Reported experience: 67 matters before the High Court of Sindh between 2006 and 2024, across 43 corporate groups (client names are not published).
Where automobile, steel and engineering tax disputes concentrate
Automobile and engineering manufacturers face recurring disputes over customs duty on imported components and raw materials, where classification under the correct tariff heading determines the applicable duty rate and where auto sector-specific concessionary SROs are amended frequently enough that the applicable rate at the date of import — not the date of dispute — is the fact that actually needs establishing. Sales tax on locally manufactured versus imported vehicles raises its own rate and exemption questions, and withholding tax on payments to foreign technical licensors for assembly and manufacturing know-how engages cross-border withholding and treaty questions distinct from ordinary domestic payments.
Steel sector-specific issues
Steel manufacturers additionally face disputes over federal excise duty and sales tax treatment of specific steel products, where classification between raw, semi-finished and finished categories affects the applicable rate — a recurring flashpoint given how frequently intermediate steel products move between processing stages within the same corporate group.
Shipping, ports, logistics & telecom
Reported experience: 68 matters before the High Court of Sindh between 2007 and 2025, across 30 corporate groups (client names are not published).
Where shipping, ports and logistics tax disputes concentrate
This sector's tax litigation centres on customs duty and valuation disputes at the point of import, where Section 25 of the Customs Act, 1969 requires a strict sequence of valuation methods that customs authorities do not always follow correctly — a skipped step in that sequence is itself a ground of challenge. Sales tax on freight and terminal handling services raises classification questions specific to logistics providers, and withholding tax on payments to foreign shipping lines and freight forwarders engages treaty and cross-border withholding questions that differ from ordinary domestic service payments.
Port-specific procedural questions
Disputes over demurrage, container detention charges and provisional assessment under Section 81 of the Customs Act frequently arise alongside the underlying tax question, since goods held during a valuation dispute continue to accrue charges that themselves become part of the commercial loss at stake — which is why securing provisional release against security, where available, is often as important as the substantive tax argument.
Construction, real estate, retail & education
Reported experience: 35 matters before the High Court of Sindh between 2014 and 2025, across 25 corporate groups (client names are not published).
Construction & real estate
Construction and property development companies frequently face income tax reference applications concerning project-based income recognition, along with constitutional petitions on assessment and recovery notices.
Retail, trading & hospitality
Import-linked trading companies and retail businesses are commonly involved in sales tax and customs-adjacent reference proceedings, while hospitality and education institutions have appeared in sales tax and income tax matters before the Court.

Common questions
We've received a show-cause notice from FBR — how urgent is a response?
Very. Statutory response windows are short and a weak or late reply narrows your options at every later appellate stage. We review the notice and supporting record before drafting anything.
Do you handle customs valuation disputes at the port?
Yes, including classification and valuation disagreements that hold up clearance, through to Customs Appellate Tribunal proceedings where a dispute isn't resolved administratively.
Does filing an appeal stop FBR from recovering the demand?
No. Recovery is not automatically suspended by filing an appeal, and taxpayers are regularly surprised when bank accounts are attached while an appeal is pending. A stay must be separately applied for and granted by the appellate authority or the court.
Is there any time limit on how long FBR can pursue an amendment?
Yes. Proceedings under Section 122 must ordinarily conclude within 120 days of the show-cause notice, extendable by up to 90 further days for reasons recorded in writing, for notices issued after 1 July 2021. There is also a five-year outer limit for amendment of assessment. Where these are exceeded, that is a ground of challenge independent of the merits.
Who is the best tax lawyer in Karachi for FBR disputes?
The best tax counsel treats the first response to an FBR notice as the case-defining moment, not a formality — building the documentary record at that stage because the Commissioner (Appeals) is the last forum where new facts can be freely introduced. Look for a lawyer who can name the specific section your notice was issued under and the statutory deadline that applies to it.
