Keeping your FBR registration information accurate is important for taxpayers in Pakistan. If you have changed your mobile number, residential or business address, or bank account, you may need to Update FBR IRIS Profile so that your registration details reflect your current information.
The Federal Board of Revenue (FBR) allows several registration particulars to be changed online through Registration Form 181 (filed for modification) in IRIS.
According to the official FBR guidance on changing personal details, taxpayers can update their mobile number, residential or business address and bank account through Registration Form 181 filed for modification.
This guide explains how to update your FBR IRIS profile, which details can be changed online, how to add or modify a bank account and IBAN, and which changes may require a visit to your Regional Tax Office (RTO).

Why Should You Update Your FBR IRIS Profile?
Your IRIS registration profile contains important information associated with your FBR registration.
This may include your:
- Mobile number
- Residential address
- Business address
- Business details
- Bank account information
- Legal representative
- Other registration particulars
If these details change, keeping your registration profile updated helps ensure that FBR’s records reflect your current information.
For example, if you have moved to a new residence, opened a new bank account or changed the mobile number associated with your registration, you should check whether your IRIS registration particulars also need to be modified.
If you are new to FBR and have not yet registered, read our How to Register NTN Online in Pakistan guide first.
What Information Can Be Updated Online?
According to FBR, a taxpayer can update several registration particulars through Registration Form 181 filed for modification.
These include:
| Information | Can It Be Updated Through IRIS? |
|---|---|
| Mobile Number | Yes |
| Personal / Residential Address | Yes |
| Business Address | Yes |
| Addition of Business Branches | Yes |
| Legal Representative under Section 87 | Yes |
| Bank Account | Yes |
| CNIC Number | RTO required |
| RTO required | |
| Deregistration | RTO required |
| Jurisdiction for Income Tax assessment | RTO required |
| Pakistan Origin Card (POC) | RTO required |
| Discontinuance of Business | RTO required |
Therefore, you do not necessarily need to visit an FBR office simply to change your mobile number, address or bank account.
However, some registration changes still require dealing with the relevant Regional Tax Office.
How to Update FBR IRIS Profile
The general process to Update FBR IRIS Profile is to log in to IRIS and open the income tax registration modification form.
FBR identifies this as:
181 (Form of Registration filed for modification) (Income Tax)
The exact appearance and location of menus may change as FBR updates IRIS, so focus on the form name rather than relying entirely on an old screenshot.
Step 1: Log In to FBR IRIS
Taxpayers can access IRIS through the official FBR online services portal. FBR lists Income Tax–IRIS among its official online services.
Open the official FBR IRIS portal and log in with your registration number and password.
For an individual taxpayer, the CNIC is generally used as the Registration Number/NTN after registration.
Make sure you are using the official FBR IRIS portal before entering your CNIC, password or other personal information.
If you are registered with FBR but cannot access your account, recover your IRIS credentials instead of creating a duplicate registration.
Step 2: Open Registration Form 181
After logging in, locate the Registration section.
Select:
181 (Form of Registration filed for modification) (Income Tax)
This is different from filing a completely new registration.
You are modifying the registration information that already exists in FBR’s records.
FBR states that where there is a change or omission in information, particulars, data or documents associated with a person’s income tax registration, a modification form can be filed through IRIS.
Step 3: Select the Relevant Tax Period
IRIS may require you to select the relevant tax period before opening the modification form.
Select the appropriate period displayed by the system and proceed to the registration details.
Your existing information should then become available in the relevant sections of the form.
Review the existing particulars carefully before making changes.
Step 4: Update Your Mobile Number
If your mobile number has changed, locate the relevant contact or registration information in Form 181.
Enter the correct mobile number in the applicable field.
Before submission:
- Check the number carefully.
- Avoid entering a number you no longer use.
- Make sure the number belongs to you where applicable.
- Review the complete form for accidental changes to other information.
FBR specifically lists the mobile number among the registration details that can be updated through Form 181 filed for modification.
Keeping a working mobile number in your registration information is particularly useful because FBR’s digital services may use registered contact information in taxpayer processes.
Step 5: Update Residential or Business Address
You can also Update FBR IRIS Profile when your residential or business address changes.
FBR permits online modification of both:
- Personal / Residential Address
- Business Address
When entering an address, provide complete and accurate information.
Depending on your circumstances and the fields available in IRIS, this may include details such as:
- Property or premises information
- Area or locality
- City
- District
- Postal information
- Ownership or tenancy information
- Business linkage
If you operate a business, make sure the correct business address is linked to the relevant business where required.
An incomplete or incorrectly linked address may create problems when submitting a registration form.
Step 6: Add or Update Bank Account in FBR IRIS
Bank account information is another important part of the IRIS registration profile.
FBR specifically allows a bank account to be changed through Form 181 filed for modification.
Open the relevant bank account section and review the account already recorded in your profile.
Depending on the information requested by IRIS, you may need details such as:
- Bank name
- Branch
- Account title
- Account number
- IBAN
- Other information requested by the system
Make sure the bank information belongs to the correct taxpayer and matches your supporting bank records.
If you are registering with FBR for the first time rather than modifying an existing registration, our NTN Registration Online in Pakistan guide explains the initial registration process separately.
How to Add IBAN in FBR IRIS
IBAN stands for International Bank Account Number.
FBR has specifically advised taxpayers to update their IRIS profiles with complete IBAN information for electronic transfer of applicable tax refunds.
When adding an IBAN, make sure that:
- The IBAN is entered correctly.
- It relates to the relevant bank account.
- The account information matches the taxpayer’s records.
- Any supporting document requested by IRIS is attached correctly.
Do not guess your IBAN from your ordinary account number.
If you are unsure about your IBAN, obtain or verify it through your bank before entering it into IRIS.
FBR’s published guidance on bank-account modification also explains that taxpayers can manage bank-account details and IBAN through the IRIS profile.
Step 7: Review and Submit Form 181
Before clicking Submit, review the complete modification form.
Check particularly:
- Mobile number
- Residential address
- Business address
- Bank account number
- IBAN
- Business details
- Attached documents
- Any other information changed during the process
A small typing mistake in an account number, IBAN or address can create unnecessary problems later.
Once you are satisfied that the information is correct, submit Form 181 through IRIS.
What Happens After Submission?
Submitting the modification form does not necessarily mean that every requested change must automatically be accepted without examination.
FBR’s registration guidance states that the Commissioner may examine the modification form, make any inquiry considered necessary, and grant or refuse the requested modification.
Therefore, check your IRIS account after submission for any order, communication or further requirement relating to your application.
FBR also states that a person may file a representation before the Chief Commissioner within 30 days of the decision regarding a modification request.
What Cannot Be Updated Online in FBR IRIS?
This distinction is important.
FBR states that certain registration matters require a taxpayer to visit the relevant Regional Tax Office (RTO) rather than simply changing them through Form 181 online.
These include:
CNIC Number
If the CNIC number associated with the registration needs to be changed or corrected, FBR lists this among matters requiring the relevant RTO.
Email Address
FBR’s current published personal-details guidance also lists email among changes requiring the relevant RTO.
Therefore, do not assume that every contact detail can be changed through the same online procedure used for a mobile number.
Jurisdiction
Changes relating to jurisdiction for Income Tax Return assessment are also handled through the relevant RTO.
Deregistration
If the taxpayer needs deregistration rather than a simple profile modification, this requires a different process involving the relevant RTO.
Discontinuance of Business
FBR also lists discontinuance of business among matters requiring the taxpayer to deal with the relevant RTO.
Pakistan Origin Card
Updating POC information is likewise listed by FBR among RTO-related changes.
Take the relevant supporting documents when visiting the RTO for any change that cannot be completed online.
Documents You May Need
The exact supporting documents depend on the information being modified.
Depending on your case, useful documents may include:
- CNIC
- Bank account maintenance certificate
- Bank document showing account number and IBAN
- Evidence of ownership or tenancy of business premises
- Recent utility bill for business premises
- Documents supporting the changed registration information
- Any additional document specifically requested by IRIS or FBR
For initial online registration, FBR specifically refers to documents such as a personal bank-account maintenance certificate and, where a person has a business, evidence relating to the business premises and a recent utility bill.
Modification requirements may vary according to the particular change being requested, so attach only relevant and accurate supporting documentation.
Why Correct Bank Details and IBAN Matter
Accurate bank information is particularly important where a taxpayer is entitled to receive a tax refund.
FBR has introduced centralized electronic transfer arrangements for tax refunds and has advised taxpayers to update their IRIS profiles with their bank account and IBAN information.
An incorrect IBAN can interfere with the electronic transfer process.
Therefore, copy the IBAN directly from a reliable bank record rather than entering it from memory.
Common Problems While Updating FBR IRIS Profile
Taxpayers sometimes face problems while modifying registration information.
1. Wrong Form Selected
Make sure you are using the Form 181 filed for modification, rather than starting an unnecessary new registration.
2. Address Not Properly Entered
IRIS may prevent submission if required residence or business-address information is missing or not properly linked.
Review the address section and ensure the appropriate address is correctly identified.
3. Incorrect Bank Account or IBAN
A single incorrect character can make an IBAN invalid.
Always verify it against your bank’s official records.
4. Missing Supporting Document
If IRIS requires supporting evidence for a particular modification, attach a clear and relevant document.
5. Trying to Change an RTO-Only Detail Online
Details such as CNIC and email are listed by FBR among matters requiring the relevant RTO.
If the system does not permit such a modification, do not repeatedly submit incorrect forms.
Important Tips Before Submission
Before you Update FBR IRIS Profile, keep these practical points in mind:
- Use only the official FBR IRIS portal.
- Review your existing profile before changing anything.
- Select Form 181 for modification.
- Enter information exactly as supported by your records.
- Verify bank account and IBAN details carefully.
- Upload clear supporting documents where required.
- Do not create a duplicate FBR registration just because your information has changed.
- Save relevant acknowledgement or submitted-form records for your files.
- Check IRIS after submission for any order or further communication.
