Every profit-bearing bank account in Pakistan — savings accounts, fixed deposits, National Savings certificates — has tax withheld at source under Section 151 of the Income Tax Ordinance. The rate depends entirely on whether you're on the Active Taxpayer List: filers pay 15%, non-filers pay 35%. On a decent-sized fixed deposit, that gap can run into hundreds of thousands of rupees a year.
How Section 151 Works
Banks, financial institutions, and National Savings Scheme offices are required to deduct withholding tax automatically whenever they credit profit to your account — you never have to calculate or pay this yourself, it just comes off the top.
| Investment Type | Filer Rate | Non-Filer Rate | Adjustable? |
|---|---|---|---|
| Savings account profit | 15% | 35% | Yes, via annual return |
| Fixed / term deposit | 15% | 35% | Yes |
| NSS certificates (DSC, SSC, RIC) | 15% | 35% | Yes |
| Prize bond winnings | 15% | 25% | Final if under Rs. 10,000 |
| Mutual fund dividend | 15% (equity) / 25% (debt) | Higher rates apply | Yes |
The word "adjustable" matters here — filers can declare this income in their annual return, claim the deducted tax as a credit, and get a refund if their actual tax liability turns out lower. For non-filers, the 35% deducted is final; there's no return-filing route to a refund on it.
What the Gap Looks Like in Rupees
| Investment | Amount | Annual Profit | Filer Tax | Non-Filer Tax |
|---|---|---|---|---|
| Savings account | Rs. 500,000 | Rs. 65,000 | Rs. 9,750 | Rs. 22,750 |
| 1-year fixed deposit | Rs. 1,000,000 | Rs. 150,000 | Rs. 22,500 | Rs. 52,500 |
| 3-year Defense Savings Certificate | Rs. 2,000,000 | Rs. 320,000 | Rs. 48,000 | Rs. 112,000 |
The pattern repeats at every scale: the non-filer rate is more than double the filer rate, and the difference only grows as the deposit amount rises.
National Savings Products — One Exception Worth Knowing
Most NSS products — Defense Savings Certificates, Special Savings Certificates, Regular Income Certificates, Pensioners Benefit Accounts — follow the same 15%/35% split. The one notable exception is the Bahbood Savings Certificate, reserved for senior citizens and widows, where profit is tax-free regardless of filer status. Everything else in the NSS family follows the standard filer/non-filer split.
Cash Withdrawal Tax Is a Related Trap
Separate from bank profit tax, Section 231A charges non-filers 0.6% on cash withdrawals above Rs. 50,000 in a single day (aggregated across withdrawals). Filers pay nothing on this. Someone withdrawing Rs. 100,000 in cash as a non-filer loses Rs. 600 to this alone — and for shopkeepers or traders who withdraw cash daily, that adds up to a meaningful annual cost that disappears entirely once they're on the ATL.
Claiming Your Credit at Return Time
- Get an annual profit/tax deduction certificate from your bank (most provide this online)
- Declare the profit under "Income from Other Sources" in your IRIS return
- Enter the tax already deducted by the bank as a withholding credit
- If your actual computed tax liability is lower, the difference comes back as a refund
A retired person whose only income is NSS profit, for example, might have an actual computed tax liability far below what was deducted at 15% — filing a return and claiming that difference back is often worthwhile, something a non-filer paying 35% has no route to at all.
Multiple Accounts, One Return
If you hold savings accounts, fixed deposits, and NSS certificates across several banks, each institution deducts tax independently. Everything gets reconciled together in your annual return — all income sources and all withholding credits are combined, and the final payable or refundable amount is calculated against your actual total tax liability for the year.
