Missing an FBR deadline can knock you off the Active Taxpayers List and trigger penalties and higher withholding. This calendar consolidates the key statutory dates for Tax Year 2026-27 so you can plan ahead. Confirm each date against the latest FBR notification, as the Board frequently grants extensions.
Salaried slabs verified: Finance Act 2026 (Finance Bill 2026-27 passed National Assembly, June 2026). Business income slabs, withholding rates, and deadlines: confirm with a consultant or at fbr.gov.pk before filing. Individual figures still flagged where not yet confirmed.
Annual Return Deadlines

|---|---|---|
| Income Tax Return (Individuals & AOPs), TY 2026 | 30 September 2026 | Salaried, business, AOP |
| Income Tax Return (Companies), TY 2026 | 31 December 2026 | Companies (Dec year-end) |

What is the last date to file income tax return in Pakistan for 2026?
For individuals and AOPs, the statutory due date for Tax Year 2026 is 30 September 2026, though FBR commonly grants extensions.
Treat 30 September as the real deadline, not the extension. Filers who wait for an extension and then miss it land on the late-filers list, which now carries a surcharge to rejoin the ATL. File early and you avoid the portal congestion in the final week too. (confirm current amount with FBR)
Monthly & Quarterly Obligations
| Obligation | Frequency | Due |
|---|---|---|
| Sales Tax Return (FBR) | Monthly | 18th of following month |
| Withholding Statement (u/s 165) | Quarterly | As notified |
| PRA Sales Tax on Services (Punjab) | Monthly | 15th of following month |
Advance Tax Instalment Dates

Late-Filing Penalties
- Removal from the Active Taxpayers List until a surcharge is paid.
- Higher withholding-tax rates on banking, property and vehicle transactions as a non-filer.
- Statutory penalty per day of default, subject to a minimum.
How to Use This Tax Calendar to Avoid Penalties
The most effective strategy is to treat each FBR deadline as a hard stop, not a target. Set a phone reminder seven days before every deadline in the calendar above so you have a full week to gather documents, review figures, and submit without the portal congestion that builds in the final 48 hours. This seven-day buffer is especially important for the annual income tax return deadline of 30 September, when IRIS slows significantly under load.
For advance tax, make your payment a few days early rather than on the last day. Late or short payment of advance tax attracts a default surcharge at KIBOR plus 3 per cent per annum on the shortfall, calculated from the due date to the actual payment date. A payment made even two or three days early eliminates this exposure entirely. Use the IRIS e-payment channel rather than paying over the counter at a bank branch — e-payments are auto-linked to your tax profile within 24 hours, whereas manual CPR challans sometimes take several working days to appear on your ledger.
Keep physical printouts or PDF copies of every CPR (Computerized Payment Receipt) and every return acknowledgement. IRIS does retain these electronically, but having your own archive means you can resolve any discrepancy with FBR without waiting for a data correction. If you engage Kamboh Associates for filing, we store copies of all submissions in your client file as a matter of routine, giving you a second backup at no extra charge.
FBR Late Filing Penalties — Quick Reference
These are the statutory penalties that apply when deadlines are missed. Confirm current amounts at fbr.gov.pk or with a consultant, as FBR may revise penalty rates through Finance Acts or SROs.
- Income tax return filed after 30 September: Rs. 1,000 per day of default, up to a maximum of 50 per cent of the tax payable for the year. The minimum penalty applies even if no tax is due.
- Advance tax — late deposit: Default surcharge at KIBOR plus 3 per cent per annum on the amount not deposited by the due quarterly instalment date, running until actual payment.
- Withholding tax monthly statement (section 165) — late filing: Rs. 2,500 per day for each day the statement remains unfiled beyond the due date.
- Sales tax return — late filing: A fixed penalty of Rs. 10,000 per return per month of default, in addition to any additional tax on late payment of the net sales tax amount.
- Removal from ATL: Non-filers are automatically excluded from the Active Taxpayers List, triggering higher withholding rates on banking, property, and vehicle transactions until they rejoin by filing and paying any applicable surcharge.
Advance Tax Quarterly Deadlines — Detailed Breakdown
Each advance tax instalment under Section 147 covers a specific quarter of the tax year, and the due date falls at the end of that quarter. Q1 is due on 25 September and covers income earned during April to June of the preceding year — this is the first instalment for Tax Year 2026-27. Q2 falls on 25 December and covers the July to September period. Q3 is due on 25 March and covers October to December income. Q4, the final instalment, is due on 15 June and covers the January to March quarter.
Each quarter's payment is calculated as one quarter of your estimated annual tax liability for the year, minus any withholding tax already deducted at source during that period (such as bank profit WHT or WHT collected by customers under Section 153). This net figure is what you remit as the quarterly instalment. Businesses with annual turnover above Rs. 250 million must also pay 1% minimum tax under Section 113 alongside their advance tax, so their quarterly calculation involves an additional step. To make the payment, log into IRIS and go to the Payments section — select CPR type "Advance Tax" from the dropdown, complete the challan with the relevant quarter's period, pay via internet banking, and attach the downloaded CPR receipt to your quarterly return submission so the payment is correctly matched to your tax account.
