Paying tax through a PSID: the four fields that matter
Paying tax in Pakistan is mechanically simple and goes wrong often, almost always for one of two reasons: a slip generated but never settled, or a slip settled against the wrong field. Both are avoidable in under a minute of checking.
What a PSID actually is
A Payment Slip Identification is a reference generated in IRIS that tells the banking system what your payment is for. It carries four determinative fields:
| Field | What it controls |
|---|---|
| Taxpayer | Whose account the credit attaches to. A payment against the wrong registration is a credit for someone else |
| Tax year | Which year the payment settles. Paying the wrong year leaves the intended year outstanding |
| Payment head or nature | Which liability is being settled — tax payable, advance tax, penalty, default surcharge, or the section 182A restoration surcharge |
| Amount | What is settled; a short payment leaves a balance accruing |
The sequence
- Complete the computation so you know the exact amount and what it is for.
- Generate the PSID in IRIS, selecting taxpayer, tax year, head and amount.
- Check all four fields on screen before proceeding. This is the checkpoint.
- Settle the slip through an accepted channel — bank counter, internet banking, mobile banking, ATM or another available route.
- Obtain the Computerised Payment Receipt. This is your evidence of payment.
- Confirm the credit appears against your registration for the correct year and head.
- Reference it in the return and store the receipt with that year records.
You draw a salary, tax is deducted at source every month, and you want the return filed properly without spending a weekend inside IRIS.
The gap between step 2 and step 4
This is the failure that recurs every filing season. A taxpayer generates the slip, sees a reference number, submits the return and considers the matter finished. The slip was never settled, so the liability remains outstanding with default surcharge accruing quietly.
The check is simple: a generated PSID gives you a reference; a settled PSID gives you a Computerised Payment Receipt. If you do not have the receipt, you have not paid. See the filing sequence.
Different payments, different heads
| What you are paying | Keep it distinct because |
|---|---|
| Tax payable with the return | Settles your assessed liability for that year |
| Advance tax instalment | Belongs to a specific period; misallocation produces default surcharge on the instalment |
| Section 182A restoration surcharge | Buys Active Taxpayer List inclusion; separate from tax payable |
| Penalty under section 182 | A consequence of default, separate again |
| Default surcharge | Accrues on late payment; distinct from penalty |
| Withholding tax deposited as an agent | Attaches to the payees, not to your own liability |
A withholding agent depositing under the wrong head is a particular problem, because the credit never appears for the supplier or employee it was deducted from — and they will come back to you for it. See the rate card guide.
Choosing a payment channel
Once a slip is generated, several routes will settle it, and the practical differences matter more than they appear:
| Channel | Practical note |
|---|---|
| Bank counter | Reliable and produces a stamped record; slower, and subject to banking hours near a deadline |
| Internet or mobile banking | Fastest for most taxpayers; confirm the receipt is generated rather than assuming the debit is sufficient |
| ATM | Available outside hours; retain the slip and confirm the receipt separately |
| Alternate delivery channels | Availability varies by bank; check before relying on one close to a deadline |
What to keep
- The Computerised Payment Receipt for every payment, filed by tax year.
- The return acknowledgement for the same year, stored alongside it.
- A simple schedule of payments made — date, amount, year, head, receipt reference — which makes the annual reconciliation and any refund claim straightforward.
- For advance tax, the instalment schedule showing what was due and when it was paid.
That schedule is also what you produce if a credit is ever questioned, and it takes minutes to maintain against hours to reconstruct — bookkeeping for tax compliance.

Questions people also ask
I generated a PSID. Is my tax paid?
No. A PSID is a payment instruction with a reference number; it is not a payment. Until it is settled through a bank counter, internet banking, an ATM or another accepted channel, nothing has been paid. Every year taxpayers generate a slip in September, believe they have filed and paid, and discover in March that only the return was submitted.
What happens if I select the wrong payment head?
The payment lands against something other than the liability you intended to settle. That means your intended liability remains outstanding — accruing consequences — while a credit sits somewhere you did not want it. Correcting it is a procedure rather than a transfer, so check the head before settling rather than afterwards.
Can I pay in instalments against one PSID?
A slip is generally settled as a single payment for the amount stated. Where you intend to pay a liability in parts, generate separate slips rather than part-paying one. For advance tax instalments, each instalment is its own payment for its own period and should be kept distinct in your records.
How do I prove I paid?
The Computerised Payment Receipt issued when the slip is settled is your evidence, and it is what you retain and reference in the return. Keep it with the acknowledgement for that tax year. A bank transaction record alone is weaker, because it does not show which liability the payment attached to.
The payment does not show against my account. What now?
Check the receipt for the taxpayer registration, tax year and head first — most cases are a field error rather than a lost payment. If all four fields are correct and the credit still does not appear after a reasonable period, raise it with the bank and with FBR, producing the receipt. Do not simply pay again.
