Adding a sole proprietorship business to your National Tax Number (NTN) is an essential step for individuals who wish to operate a business officially under their own name and open a dedicated business bank account. The Federal Board of Revenue (FBR) provides an online portal, IRIS, where taxpayers can seamlessly register or modify their income tax registration profiles without needing to visit an office physically.

Whether you are starting a fresh business or registering additional ventures under your existing NTN, the FBR IRIS portal streamlines the modification process. This guide provides a detailed, step-by-step explanation of how sole proprietors can modify their registration, add business details, link property addresses, attach the required documentation, and verify their updated registration status online.

Step 1: Accessing the FBR IRIS Portal and Initiating Modification

To begin the process, navigate to the official FBR IRIS portal at iris.fbr.gov.pk.

• For New Taxpayers: If you do not already possess an NTN, click on New Registration on the home page and complete the simple registration steps to generate your NTN.
• For Existing Taxpayers: If you already have an active NTN, simply log in using your credentials.

Accessing Form 181

1. Once logged in, locate the top navigation bar and select the Registration tab.
2. Under the Forms section (found in the second column), select 181 Form of Registration File for Modification Income Tax.
3. Select the relevant Tax Period. The income tax period in Pakistan runs from July 1st to June 30th. For example, for the tax year ending June 2024, select 2024 to automatically load the tax period from 1st July 2023 to 30th June 2024.
4. Click Continue to load the modification form.

Step 2: Entering Business Details and Selecting Activities

The Modification Form includes several tabs: Property, Business, Link, Attachment, and Bank Account. To register a sole proprietorship, navigate directly to the Business tab.

Adding New Business Information

1. Click the Plus (+) icon designated for Add New Business Detail.
2. Enter your exact Business Name.
3. Specify the Acquisition Date (the date you acquired or started the business).
4. Set the Capacity by selecting whether you are an Owner or a Tenant (select Owner for sole proprietorships where applicable).

Defining Business Activities

1. Activity Type: Choose the nature of your registration. If you are not registering for Sales Tax or specialized FBR activities, select Principal Activity.
2. Business Section/Category: Search for and select your specific industry category (e.g., trader, manufacturer, general order supplier, or information technology). For general order suppliers, search for and select Other Service Activities Services General Order Suppliers.
3. Re-enter or verify the business start date and click OK. The activity will now be added with the “Principal” box checked.

Step 3: Linking Business Property Details

After specifying your business activity, you must link a valid property address to the business profile.

1. Under the business entry, click on Link Business Address.
2. Using Home Address: If your business is operated from home, you may select your existing residential property address.
3. Adding a New Property: If the business address is different, navigate to Add Other Property Details and specify:
   • Property Type: Select whether the property is Residential, Commercial, or Industrial.
   • Property Sub-Type: Choose House, Flat, Bungalow, or Apartment.
   • Measurement Unit & Size: Specify the measurement unit (e.g., Marla, Square Feet, or Square Yard) along with the complete address.
   • City and Town: Search and select your city and relevant town. If the town is unknown, selecting the city alone is sufficient.
   • Capacity and Ownership Share: If the property is owned by parents rather than directly by you, select Benami Lease Tenancy and assign a minimum share value of 1.
4. Select the completed property entry and click OK to link it to your business profile.

Step 4: Uploading Required Attachments and Submitting

To complete the modification request, navigate to the Attachment tab to upload necessary supporting documentation.

Required Documents

• Modification Form: Print out and attach the 181 Form of Registration File for Modification (by clicking the Plus icon if required).
• Evidence of Business Premises: Attach proof of ownership or tenancy (e.g., rental agreement or property documents under parents’ names).
• Utility Bill: Attach a recent electricity bill for the business premises (not older than three months).

Once all required documents are attached, click the Submit button. Upon successful submission, your application will move from the out-box to the Complete Task section.

Step 5: Verifying Business Registration Status

To verify whether your newly added business has been successfully updated in the official FBR system:

1. Visit the FBR NTN Inquiry or Taxpayer Profile Inquiry portal.
2. Enter your CNIC Number and complete the security verification code.
3. Click Search. After a short processing period, your profile inquiry will display your newly added sole proprietorship business details.
