What withholding tax really is.
Withholding tax (WHT) is income tax collected by the payer on behalf of the FBR before the payment lands in the recipient bank account. If your Karachi trading company pays a Lahore consultant PKR 100,000 for services, you do not write a cheque for 100,000. You write 90,000 (or 88,000 if the consultant is a non-filer), deposit the remaining 10,000 (or 12,000) into the FBR account on the consultant CNIC/NTN, and issue a CPR (computerized payment receipt) as proof. The consultant claims the deducted amount as advance tax against their year-end return.
The mechanism exists because the FBR cannot chase every freelancer for income tax. By forcing the corporate payer to collect at source, the government captures revenue from the formal sector and uses the WHT statement (form 165) as a cross-check against income returns. If you receive WHT credit you did not declare as income, an FBR audit notice usually arrives within 18 months.
Section 153: the rates that catch almost everyone.
Section 153 covers payments for goods, services, and execution of contracts. For services, the rate in tax year 2026 is 11 percent for filers (companies) and 22 percent for non-filers. For specified services like IT and IT-enabled exports, a reduced 0.25 percent applies. For sale of goods, the rate is 5.5 percent for companies and 6.5 percent for other taxpayers, doubled for non-filers. For contracts (typically construction and supply combined), 7.5 percent for filers, 15 percent for non-filers.
Worked example: a Faisalabad textile mill pays a Karachi clearing agent PKR 250,000 for customs clearance services. The agent is a filer. WHT = 250,000 × 11% = 27,500. The mill pays the agent 222,500 and deposits 27,500 into the FBR account against the agent NTN by the 7th of the following month. The mill expenses the full 250,000 in its books; the agent declares 250,000 as revenue and claims 27,500 as advance tax credit.
- Services to filers: 11 percent (Section 153(1)(b)).
- Services to non-filers: 22 percent.
- Goods to companies (filer): 5.5 percent.
- Goods to other taxpayers (filer): 6.5 percent.
- Contracts to filers: 7.5 percent.
- IT export services: 0.25 percent under Section 154A.
Other common WHT sections you will hit.
Section 149 covers salary. Every employer must deduct income tax from monthly salary using the salary slab and deposit it by the 15th of the following month. For a Karachi employee earning PKR 200,000 a month (PKR 2,400,000 annually), the tax for tax year 2026 is approximately PKR 165,000, deducted as PKR 13,750 a month. Section 155 covers rent. A company paying PKR 150,000 a month for office rent in Gulberg deducts 5 percent (filer) or 10 percent (non-filer) and pays the landlord the balance.
Section 233 covers commission, including digital marketing and influencer payouts. The rate is 12 percent for filers, 24 percent for non-filers. Section 236G/H cover dealer and distributor advance tax (collected by the manufacturer). Section 231A is the bank cash withdrawal tax (now repealed for filers but still relevant for non-filers above PKR 50,000 daily withdrawals).
Filer vs non-filer: the doubled rate that changes behaviour.
Every WHT rate has a filer schedule and a non-filer schedule. The non-filer rate is usually double. The intent is to push people onto the active taxpayer list (ATL). A Faisalabad fabric supplier who is a non-filer pays 13 percent WHT on every sale to a corporate customer instead of 6.5 percent. Over a year, on PKR 50 million of sales, that is an extra PKR 3.25 million held by FBR until the supplier files. Many never file, and the money is essentially forfeit.
Check ATL status before you pay anyone: go to fbr.gov.pk and use the Online Verification of ATL with the recipient CNIC or NTN. Nonari can be set to refuse to mark an invoice as paid until the supplier ATL status is confirmed in the last 30 days, which avoids the embarrassing case where you over-pay an old supplier whose ATL lapsed in March.
Filing the monthly 165 statement.
By the 15th of every month, every WHT agent must file a 165 statement on Iris listing every deduction made in the previous month: payee name, CNIC/NTN, section, gross amount, WHT rate, WHT amount, and CPR number. Miss it, and the penalty is PKR 5,000 per day up to a maximum of PKR 500,000 plus a default surcharge of 12 percent per year on the unpaid tax. A Lahore trading company that forgets the 165 for three months pays PKR 450,000 in penalties alone before any tax adjustment.
The mechanical step is brutal if you do it manually. You log into Iris, click 165, paste a CSV with 200 rows, validate, and submit. Half the time the CNIC formatting causes a rejection and you re-paste. Nonari produces the 165 CSV from the same vendor payments table that posts to the GL, so the numbers reconcile to the trial balance by construction. The journal entry on every WHT deduction is: DR Vendor Payable 100,000 / CR Cash 89,000 / CR WHT Payable 11,000.
How the deducted party claims the credit.
You are on the receiving end of WHT just as often as you are the agent. Every corporate customer that pays you for services deducts 11 percent and gives you a CPR. At year-end, you file your income return (form 114 or 116) and claim the sum of all CPRs as advance tax. If your final tax liability is PKR 800,000 and your CPRs total PKR 1,200,000, you have a refund of PKR 400,000 to claim from FBR.
The refund process is the painful part. File a 170 refund application within two years of the return, attach the CPRs, attach the bank statement, attach the audited accounts. FBR processes refunds in 6 to 18 months. For SMBs sitting on PKR 5 million in stuck refunds, this is real working capital pain. Two practical workarounds: apply for an exemption certificate under Section 153(4) if your tax liability is consistently below the WHT, or adjust the credit against your monthly advance tax under Section 147 instead of waiting for a refund.
The mistakes that trigger audits.
Mistake one: deducting at the wrong rate. Paying a non-filer at the filer rate is the single most common error, usually because the bookkeeper used last month ATL status without re-checking. Mistake two: depositing under the wrong section. WHT on services paid under Section 234A (transport) instead of 153 means the recipient cannot claim the credit. Mistake three: not issuing the CPR. The recipient has no proof and will demand a refund of the deducted amount from you directly.
Mistake four: late deposit. WHT deducted on October 15 must be deposited by November 7. Deposit on November 12 and the penalty is 12 percent annualized plus the default surcharge. Mistake five: forgetting Section 165 even when no payments were made. A nil 165 is still required every month. Nonari runs these checks automatically and flags any vendor payment that would violate a WHT rule before you save the bill.
