The Federal Board of Revenue (FBR) has quietly executed a massive structural overhaul of its Inland Revenue field formations across Pakistan. In an official order issued on July 16, 2026, the revenue authority has completely dismantled specific high-level tax offices, created entirely new corporate jurisdictions, and re-designated existing setups across major economic hubs including Islamabad, Rawalpindi, Lahore, and Karachi.
As mainstream media has yet to widely report this disruptive regulatory shift, PayPaysa brings you an exclusive, in-depth breakdown of these structural changes and how they immediately impact corporate taxpayers, digital business models, and filers nationwide.
1. The Big Shakeup: Key Corporate Tax Office Abolished & Created
In exercise of the powers conferred under the Federal Board of Revenue Act, 2007, and following decisions from the Board-in-Council, the FBR has implemented an immediate restructuring model:
* Abolition of CTO Islamabad: The Corporate Tax Office (CTO) in Islamabad has been officially dissolved.
* Two New Corporate Zones in RTO Islamabad: To absorb the corporate tax base from the abolished office, the FBR has established Corporate Zone-I and Corporate Zone-II under the administrative umbrella of the Regional Tax Office (RTO), Islamabad.
* New Corporate Zone in RTO Rawalpindi: A dedicated Corporate Zone has been newly minted within the Regional Tax Office (RTO), Rawalpindi to handle localized corporate portfolios.
* Creation of RTO-II Lahore: A brand-new field formation, Regional Tax Office-II, Lahore, has been formally established to partition regional workloads.
2. Mass Re-Designation: Official Nomenclature Changes
The organizational framework has shifted instantly for major field formations in Sindh and Punjab, changing how corporate taxpayers identify their respective tax offices:
| Previous Office Nomenclature | New Official Nomenclature |
|—|—|
| Medium Tax Office Karachi | Corporate Tax Office – II Karachi |
| Corporate Tax Office Karachi | Corporate Tax Office – I Karachi |
| Regional Tax Office Lahore | Regional Tax Office – I Lahore |
3. The Alphabetical Split: Finding Your New Jurisdiction in RTO Islamabad
Following the migration of corporate files into RTO Islamabad, the FBR has instituted a strict alphabetical division based on the starting character of the taxpayer’s name. This dictates exactly which Commissioner holds administrative authority:
Corporate Zone-I (RTO Islamabad)
This zone covers the Islamabad Capital Territory (ICT), Gilgit Baltistan, and Northern Areas for titles starting with a number or letters A through L:
* All companies and non-resident entities within this specific alphabetical bracket.
* All Registered Trusts, NGOs, and NPOs starting with a number or A–L.
* Associated Directors, Members, and Trustees of these corresponding corporate bodies.
Corporate Zone-II (RTO Islamabad)
This zone manages the remaining half of the corporate spectrum for the same territories where titles start with letters M through Z:
* All corporate and non-resident taxpayer accounts falling within the M–Z initial range.
* All Trusts, NGOs, and NPOs whose registered titles begin with letters M–Z.
* The respective Directors, Members, or Trustees connected to these companies.
4. RTO Rawalpindi’s New Corporate Command
For enterprises operating within the Rawalpindi Division, the FBR’s newly formed Corporate Zone under RTO Rawalpindi centralizes command over local corporate tax streams.
This specific formation now commands:
* All corporate cases, non-resident ventures, trusts, and NGOs operating inside the Rawalpindi Division boundaries.
* The structural monitoring and aggressive enforcement of withholding taxes for all taxpayers covered under its jurisdiction.
* Direct handling of cases concerning Directors, Members, or Trustees linked to these local companies.
What This Means for Businesses and Filers
> Urgent Regulatory Notice: Because this transition is marked with immediate effect, businesses previously mapping their tax compliance to CTO Islamabad must re-verify their corporate titles.
> The Pakistan Revenue Automation Limited (PRAL) is actively making the necessary configuration changes on the national e-portal. Taxpayers must keep a close eye on their e-portal profiles to ensure their filings, withholding declarations, and automated invoices are routed toward the correct corporate zone.
