Payroll Withholding: What Pakistani Employers Must Deduct

A Pakistani payroll is never just salary out and work in. In each pay run the employer acts as an unpaid collection agent for the federal tax authority, a federal old-age institution and a provincial social-security scheme, while remaining a regulated debtor to its own workers under wage legislation that dates from 1936. The obligations stack; they do not merge, and no authority forgives an employer for having paid the wrong one. This briefing sets out what must be deducted, what must be contributed on top, and what may lawfully be taken out of a pay packet, as the law stands in July 2026. Rates and thresholds move with each Finance Act and each provincial budget, so every figure-shaped item below is deliberately left for verification against the current notifications.

Section 149: the employer as withholding agent

Section 149 of the Income Tax Ordinance 2001 requires every person responsible for paying salary to deduct tax at the time of payment. The deduction is not computed on the month's cheque in isolation. It is computed on the employee's estimated income under the head "salary" for the whole tax year, taxed at the applicable rates in Division I of Part I of the First Schedule, and then withheld on an average basis across the pay periods [current salary slab rates for the tax year — TO BE VERIFIED BY REVIEWING LAWYER]. The employer is therefore making a forward projection every month: annualise the package, apply the slabs, divide, deduct. A mid-year raise, a bonus, or a joiner who arrives in month nine all change the projection and require the withholding to be trued up within the year, not left for the employee to reconcile later.

The base is wider than the basic salary line. Section 12 of the Ordinance sweeps into "salary" essentially everything that flows from the employment: wages, overtime, bonus and commission, leave encashment, most allowances, perquisites such as a company-maintained car or subsidised loan valued under the Income Tax Rules 2002, and benefits under employee share schemes [valuation rules and exempt allowances — TO BE VERIFIED BY REVIEWING LAWYER]. A payroll that withholds on basic pay and treats allowances as invisible is under-deducting every month, and the shortfall belongs to the employer as much as to the employee.

Section 149 does allow the employer to make adjustments in the employee's favour — for tax the employee has already suffered under other withholding provisions and for specified tax credits — but only against documentary evidence provided by the employee [permitted adjustments and evidence requirements — TO BE VERIFIED BY REVIEWING LAWYER]. Adjustments made on an employee's verbal assurance are the employer's problem when the return is examined.

Deposit, statements, certificates

Deducting is half the duty. The tax must be deposited into the government treasury within the period prescribed under the Income Tax Rules 2002 [deposit deadline — TO BE VERIFIED BY REVIEWING LAWYER], and the employer must file periodic withholding statements under section 165 identifying each employee, the amounts paid and the tax deducted [current filing frequency and deadlines — TO BE VERIFIED BY REVIEWING LAWYER]. Each employee is entitled to an annual certificate of the tax deducted, which is what the employee files against.

The sanctions for getting this wrong land on the employer, not the employee. Tax that should have been deducted but was not is recoverable from the employer under section 161 as though it were the employer's own liability, with default surcharge under section 205 and penalty exposure under section 182. The Ordinance also puts deduction failures at risk of expense disallowance in the employer's own return [scope of disallowance for non-deduction — TO BE VERIFIED BY REVIEWING LAWYER]. In our experience the surcharge and penalty, accrued quietly over three or four years, routinely exceed the original shortfall.

The wage floor beneath the arithmetic

Withholding arithmetic sits on top of a floor the employer does not set. Minimum wages are notified provincially — by the wage boards under the Minimum Wages Ordinance 1961 and its provincial successors, with Sindh operating its own minimum wage statute, and separate notifications for the Islamabad Capital Territory — usually revised with the annual budgets, and with distinct rates for unskilled, semi-skilled and skilled categories [current notified rates by province and category — TO BE VERIFIED BY REVIEWING LAWYER]. For payroll purposes the notifications matter twice over: they fix the lowest lawful gross for covered workers, and they drive the contribution bases described below. No deduction structure, however well-papered, may be used to bring a covered worker's wage beneath the notified floor.

The contribution stack

Two social contributions ride on the same payroll, and they are governed by different statutes, collected by different institutions and borne differently.

The first is the old-age contribution under the Employees' Old-Age Benefits Act 1976. It has two components: an employer share and a smaller employee share, each calculated as a percentage of the notified wage base [current percentages and wage base — TO BE VERIFIED BY REVIEWING LAWYER]. The employee share is the only social contribution that lawfully comes out of the pay packet. The employer share never does.

The second is provincial employees' social security — SESSI in Sindh, PESSI in Punjab, and their counterparts elsewhere — which is an employer-only contribution against wages of secured workers up to a notified ceiling [current rate and ceiling by province — TO BE VERIFIED BY REVIEWING LAWYER]. An employer that recovers this from workers has made an unlawful deduction, not a contribution.

The registration, coverage and enforcement mechanics of these institutions are a subject of their own; for the payroll function the essential discipline is narrower: know which lines are deductions from the employee, which are costs on the employer, and never let the payroll software blur the two.

What may lawfully leave a pay packet

The Payment of Wages Act 1936 and its provincial successors, including Sindh's own payment of wages legislation, work on a closed-list principle: a deduction from wages is unlawful unless the statute permits it. The permitted categories are short — fines imposed under an approved schedule with notice and subject to a cap; deductions for absence from duty, in proportion to the absence; deductions for damage or loss after the worker has been heard; charges for housing or amenities actually supplied; recovery of advances; income tax; deductions ordered by a court; and contributions to provident funds and similar approved schemes [permitted categories, the cap on fines and the aggregate ceiling on deductions — TO BE VERIFIED BY REVIEWING LAWYER]. Anything else — a "notice pay" clawback invented in a policy, a training-bond recovery never documented, a shortage in the till debited without inquiry — is recoverable by the worker before the wages authority, with compensation that can be a multiple of the amount deducted.

The deduction-obligation table

The figures belong in the current notifications, not in a briefing. The structure does not change, and it is this:

Obligation	Instrument	Borne by	When it is paid	Evidence to keep
Income tax on salary	s.149, Income Tax Ordinance 2001; First Schedule rates	Employee (deducted at source)	Each payment; deposited within the prescribed period	Payroll tax computation, deposit challans, s.165 statements, employee certificates
Old-age contribution — employer share	Employees' Old-Age Benefits Act 1976	Employer	Monthly	Contribution challans, employee registration records
Old-age contribution — employee share	Employees' Old-Age Benefits Act 1976	Employee (deducted at source)	Monthly	Pay slips showing the deduction, challans
Social security contribution	Provincial employees' social security statutes (SESSI, PESSI and counterparts)	Employer only	Monthly	Challans, secured-worker registers
Minimum wage floor	Provincial minimum wage notifications	Employer	Continuous	Wage register mapped to notified categories
Other deductions (fines, advances, provident fund, court orders)	Payment of Wages Act 1936 and provincial successors	Employee, within statutory limits	As they arise	Approved fine schedule, signed acknowledgments, deduction register

Where payroll goes wrong

Four failures account for most of the exposure we see. Withholding on basic pay while allowances travel tax-free. Promising a "net salary" in the contract and then treating the gross-up casually — the employer still bears the tax and still must compute and report it correctly. Mishandling final settlements, where leave encashment and terminal benefits have their own tax treatment [taxation of terminal benefits — TO BE VERIFIED BY REVIEWING LAWYER] and where the last pay run is the one most often improvised. And missing the July reset, when new slab rates, new wage notifications and new contribution bases all arrive at once. A structured payroll compliance review once a year, timed to the Finance Act, is cheaper than any one of these four discovered in an audit.

What this means for you

Build the payroll around the statutes, not around last year's spreadsheet. Annualise every package and re-run the section 149 projection whenever pay changes, not just in July. Keep the deduction lines and the employer-cost lines visibly separate, and let nothing leave a pay packet that a Payment of Wages authority would not recognise. File the section 165 statements on time even in months where nothing changed, and archive the challans as if you will need them in five years — because if you are audited, you will. Where the stack has drifted — allowances untaxed, an employee share over-recovered, a fine regime never approved — quantify the gap first and take advice on correcting it deliberately; our HR advisory practice spends more time repairing improvised fixes than original mistakes.
