Most businesses think of tax as something they pay on their own profits. A large part of the Pakistani income tax system does not work that way: it makes businesses collect tax from other people at the moment of payment.

Get it wrong and the liability is yours — not the supplier's, not the landlord's, not the contractor's. That is what makes this the most common and most expensive compliance failure we see.

How it works

Under the Income Tax Ordinance 2001, prescribed persons — companies, AOPs above a threshold, and others — must deduct tax at source when making certain payments, deposit it with FBR, and file periodic withholding statements.

The person paying is the withholding agent. If you should have deducted and did not, FBR recovers the amount from you, with default surcharge and penalty, and the expense may be disallowed in computing your own income — so you lose the deduction as well as paying the tax.

That second consequence is what turns a modest oversight into a serious assessment.

Payments that commonly require deduction

Rates and thresholds change with each Finance Act, so the current rate must always be checked — but the categories are stable:

  • Supply of goods
  • Services — with different treatment for various categories
  • Contracts for execution of work
  • Rent of immovable property — the obligation landlords most often assume does not exist
  • Salaries, computed on the employee's estimated annual liability
  • Dividends
  • Profit on debt — interest and bank profit
  • Commission and brokerage
  • Payments to non-residents, including royalties, fees for technical services and other Pakistan-source payments
  • Imports, at the clearance stage
  • Prizes and winnings

Advance tax is also collected on a range of transactions — vehicle registration, electricity and telephone bills, cash withdrawals in some regimes, and property transfers. See tax on rental income and property.

Filer and non-filer

The Active Taxpayers List is central to this. Rates applied to persons not appearing on the ATL are substantially higher — frequently double — and in some categories non-appearance now blocks the transaction entirely.

Practical consequences:

Check the ATL at the time of payment, not when the supplier was onboarded. Status changes, usually because a return was filed late or not at all.

Keep evidence of the status you relied on. A dated ATL check saves an argument in an audit two years later.

Get on the list yourself. For a business, filer status affects your own cost base across dozens of transactions. See registering a company.

Adjustable, minimum and final — the distinction that matters

Not all withholding is the same, and confusing the three produces wrong returns.

Adjustable: the tax deducted is credited against your final liability, and excess is refundable.

Minimum: the tax deducted is the least you will pay on that income even if your computation shows less.

Final: the deduction discharges the liability on that income entirely, and it is not recomputed.

Which applies depends on the payment type and the recipient's status. This is the point at which advice is worth taking, because the tax outcome for the same transaction can differ substantially.

Your compliance calendar

  • Deduct at the time of payment or credit, whichever is earlier — the "credit" limb catches businesses that book an expense and pay later
  • Deposit within the prescribed time, on the correct payment slip
  • Issue certificates of deduction to the payee, who needs them for credit
  • File withholding statements periodically, accurately
  • Reconcile what you deducted against what your accounts show as expenses. This is exactly the reconciliation FBR performs, and mismatches drive audits

When you have not been deducting

Very common, particularly on rent, services and payments to small suppliers.

Do not simply start next month and hope. The exposure sits in the past periods, and FBR reaches it through the same expense reconciliation described above — frequently through a monitoring of withholding taxes proceeding, which is narrower and faster than a full audit and is where most of these cases surface.

The better course is to quantify the exposure, correct the position, and deal with it deliberately. Voluntary correction is a materially better posture than being found.

See FBR audit notices.

Non-residents and treaty relief

Payments abroad are where the largest single mistakes happen. Deduction on payments to non-residents can be reduced or eliminated under an applicable double taxation treaty, but relief is not automatic — it requires the correct process and documentation, including tax residency evidence.

Paying a foreign supplier gross, without considering withholding, creates a liability the foreign supplier will not reimburse and your contract probably did not price. Address it in the contract with a properly drafted tax and gross-up clause. See the contracts every business should have in writing, branch and liaison offices and repatriating profits and capital.

Sales tax withholding is separate

Provincial and federal sales tax regimes have their own withholding rules, with their own rates, returns and registrations. Complying with income tax withholding does not discharge them. See sales tax registration and compliance.

For freelancers and IT exporters

If you receive payments rather than make them, the relevant issues are export proceeds treatment, the applicable regime for IT and IT-enabled services, filer status, and claiming credit for tax deducted at source. See freelancers and IT exporters.

How the firm can help

We review a business's withholding position across all payment categories, quantify historic exposure and advise on correcting it, represent clients in withholding monitoring proceedings and audits, obtain treaty relief on payments to non-residents, and draft tax clauses that put the burden where the parties actually intended.
