The Rs. 20,000 I Almost Left Behind: A Pakistani Engineer's Guide to Tax Adjustments Through Your Employer

I was complaining about how expensive everything had gotten. Inflation, bills, the constant small drain of card fees and ATM charges accumulating over a month. A colleague mentioned, almost in passing, that he'd just gotten his taxes adjusted through the company: card deductions, ATM withdrawals, phone bills, all of it credited back through payroll. Then he asked if I was doing the same.

I had no idea what he was talking about.

Twenty minutes later, I understood something that nobody had explained to me in years of working at a registered IT company: I had been prepaying tax on every card swipe, every ATM withdrawal, every phone and internet bill, and my employer had the legal right to adjust all of it against my income tax liability. I just had to ask.

I went back through 12 months of bank statements. Small deductions, every month, on things I barely noticed. I submitted one form. Sent one email.

This article is everything I wish someone had told me on my first day.

In Pakistan, the Income Tax Ordinance 2001 requires various institutions (banks, telecom companies, utility providers, airlines, educational institutions) to collect tax at the point of transaction and submit it to the FBR on your behalf. This is called advance tax or withholding tax (WHT).

It is not a penalty. It is not extra tax. It is a prepayment of your eventual income tax, collected in advance by whoever is facilitating your transaction.

Here's what's being deducted from you constantly, whether you know it or not:

Every one of these is adjustable against your final income tax liability. The legal basis is Section 168 of the Income Tax Ordinance: credit for tax collected or deducted at source.

The system is simple in theory: at the end of the year, you declare your income, compute your total tax, and subtract everything that was already deducted. If you over-paid, you get a refund. If you under-paid, you settle the balance.

The problem: most salaried employees never do this. Their employer deducts salary tax, submits it to FBR, and the process ends there. All the other advance taxes (the card swipes, the ATM fees, the phone bills) just stay in the FBR's pocket.

Here is where it gets interesting for IT sector employees specifically.

Your employer is legally allowed to adjust advance tax deductions made on your behalf against the income tax they withhold from your salary. This means your company's payroll team can reduce the tax withheld from your monthly salary, since you've already pre-paid part of it elsewhere.

The adjustment has to happen during the fiscal year. Pakistan's tax year runs July to June. Any advance tax deducted within the same fiscal year (e.g., July 2024 to June 2025) can be adjusted in that year's payroll.

The practical window: initiate the process 2–3 months before June. Payroll cutoff is typically the 20th of each month, so factor that in. If you miss June, you can still file for a refund directly with FBR when submitting your annual return. Having your employer adjust it in payroll is faster and simpler.

Based on the Income Tax Ordinance and confirmed by FBR's Finance Act 2025 circular, here's what's adjustable:

The core three (most relevant for everyday earners):

• Card transactions (domestic and foreign): every swipe, every online purchase
• Cash withdrawals from ATMs and bank branches
• Mobile and internet bills: postpaid, prepaid, home broadband

Additional credits worth knowing:

Charitable donations (s. 61):If you've donated to an FBR-approved institution or NGO, up to 30% of your taxable income is eligible for tax credit. You need a bank transfer or cheque as proof. Cash donations don't qualify.

Life insurance premiums (s. 62A): A tax credit is available on life insurance premiums paid to an SECP-registered company. The limit is the lower of 20% of taxable income or Rs. 2 million. The policy must not be surrendered within 2 years.

Pension fund contributions (s. 62): Contributions to an approved voluntary pension fund (Al-Meezan, UBL, MCB, NBP, etc.) are eligible for a tax credit of up to 20% of taxable income. This credit directly reduces your tax payable, not just your taxable income.

Housing loan interest (s. 64A): If you have a mortgage from a scheduled bank for construction or purchase of a house up to 1,500 sq ft, or a flat up to 2,000 sq ft, you can claim a credit on the profit on debt paid. Restored under Finance Act 2025.

Medical allowance exemption:Medical allowance up to 10% of basic salary is exempt from income tax, provided your employer doesn't already offer a reimbursement scheme.

Disability (s. 53): If you are a registered disabled individual, a 50% reduction in tax applies on salary income up to Rs. 1 million.

If you are not on the FBR's Active Taxpayers List (ATL), you are paying higher WHT rates on every transaction. Banks, telecoms, and utilities charge non-filers a premium.

Becoming a filer is free. It takes under an hour on the FBR IRIS portal using your CNIC. Once you're on the ATL:

• Your withholding rates drop
• All advance taxes become adjustable (not final)
• You build a documented tax history that matters for everything from property to vehicle registration

If you're employed and earning, there is no reason not to be a filer. The advance taxes you've paid as a non-filer are still adjustable, but at the non-filer rate. Future deductions will be at the lower filer rate once you register.

Not everything is adjustable. Some withholding taxes are designated as final taxes under the Ordinance. Once deducted, they cannot be credited against your income tax:

• Tax on dividends
• Tax on prize bonds and lottery winnings
• Tax on certain contracts specified under the Ordinance

If you're unsure whether a specific deduction is adjustable or final, your payroll team or a tax consultant can clarify.

For context: I had been employed at an eligible company for over a year before this conversation happened. I had paid advance tax on every card transaction, every ATM withdrawal, every monthly phone and internet bill, for more than a year.

When I went through 12 months of statements, the total came to Rs. 20,000+.

That's not a life-changing number. But it is real money: a month of groceries, a utility cycle, a few months of internet bills. And it was money I had legally already paid, sitting unclaimed, because I had never submitted a form.

The worse realisation: this had been happening since my first day in the industry. Multiple fiscal years. Multiple employers. Every one of them had the mechanism to help me claim it. None of them had told me to.

The engineers who know about this usually grew up in households where tax planning was just... discussed. Everyone else finds out through a colleague, years in.

This information is public. It is legal. It is unambiguously yours to claim.

But knowing it requires knowing where to look. This article is my small attempt to make the information slightly more available.

The process takes less than an hour to initiate. The rest is waiting.

The Rs. 20,000 I recovered isn't the point of this article.

The point is that I had been working in this industry for years, at companies with the exact mechanism to help me, and it had never come up: not in onboarding, not in a manager conversation, not in a company email.

If you're a team lead or engineering manager: share this. Put it in your team's onboarding. Add it to the start-of-fiscal-year checklist. The people who most need this information are the ones least likely to find it on their own.
