What Is Sales Tax Registration in Pakistan?

Sales Tax Registration is the process through which a person or business becomes registered with the Federal Board of Revenue (FBR) for Sales Tax purposes where registration is required or applicable.

FBR states that Sales Tax registration is the first step before filing a Sales Tax Return. Registration provides the relevant Sales Tax Registration Number (STRN) or access credentials for the electronic filing system.

The automated Sales Tax registration process is available through the FBR IRIS system for persons having active IRIS credentials.

Important:

Sales Tax registration should not be confused with Income Tax registration. A business may have separate Income Tax and Sales Tax compliance obligations depending on its activities and legal circumstances.

Who Needs Sales Tax Registration?

The requirement for Sales Tax registration depends on the nature of the business, taxable activities, category of taxpayer and applicable provisions of Pakistani tax law.

Depending on the circumstances, relevant businesses may include:

  • Manufacturers
  • Importers
  • Wholesalers and distributors
  • Specified retailers
  • Businesses making taxable supplies
  • Other persons required to register under applicable Sales Tax rules

Because Sales Tax registration requirements can differ according to business activity, taxpayers should check the latest FBR requirements before submitting an application.

What Is STRN?

STRN stands for Sales Tax Registration Number.

It is associated with a person's registration for Sales Tax with FBR. A registered taxpayer uses the relevant FBR electronic system to manage Sales Tax compliance and file returns.

Remember:

Having an NTN or Income Tax registration does not automatically mean that a person has completed Sales Tax registration. Sales Tax registration is a separate compliance matter.

Documents and Information Required for Sales Tax Registration

Before starting the FBR IRIS Sales Tax registration process, it is advisable to prepare the required business information and supporting documents.

Requirement Details
IRIS Credentials Active FBR IRIS credentials.
Tax Period Relevant tax period required by the registration form.
Business Information Business name, acquisition date, capacity, business activity and branch information where applicable.
Bank Account Bank account details and bank account certificate in the business name.

Step-by-Step Sales Tax Registration on FBR IRIS

Step 1: Login to FBR IRIS

Open the official FBR IRIS portal and log in using your active IRIS credentials.

Step 2: Open the Registration Menu

After logging in, go to the Registration menu.

FBR's published procedure refers to:

Form 14(1) – Form of Registration filed voluntarily through Simplified (Sales Tax)

Step 3: Select the Tax Period

Select or enter the relevant tax period requested by the system.

Step 4: Provide Sales Tax Information

Provide the required Sales Tax information.

For individuals, the registration type may require selecting whether the taxpayer is a Manufacturer or Non-Manufacturer.

For an AOP or company, FBR's procedure refers to the CNIC of the relevant member, director or principal officer along with the applicable manufacturer/non-manufacturer classification.

Step 5: Enter Bank Account Details

Enter the required bank account information and provide the bank account certificate issued in the name of the business.

Tip:

Check that the business name appearing on your bank documentation is consistent with the registration information.

Review all information carefully before submitting the registration application.

After the required information and documents have been submitted, the system processes the Sales Tax registration according to the applicable FBR procedure.

Biometric Verification After Sales Tax Registration

One of the important steps after Sales Tax registration is biometric verification.

FBR states that a person registered through the IRIS portal is required to visit a NADRA e-Sahulat Centre within 30 days for biometric verification.

Important Warning:

Failure to visit the e-Sahulat Centre or failure of biometric verification can result in removal of the registered person's name from the Sales Tax Active Taxpayer List.

What Is a Sales Tax Return?

A Sales Tax Return is a declaration submitted by a registered person for a particular tax period.

The return contains information relating to transactions, input tax, output tax, Sales Tax liability and, where applicable, refund or excess input tax.

Basic Concept

Output Tax − Allowable Input Tax = Net Sales Tax Liability

Actual calculations can involve additional adjustments, restrictions and applicable legal provisions.

Sales Tax Return Due Dates

FBR provides different Sales Tax Return categories, including monthly, quarterly, annual and final returns.

Compliance Standard Timing
Annexure C 10th of the following month
Payment 15th of the following month
Electronic Return 18th of the following month

These are the standard monthly dates published by FBR. Different categories can have different filing arrangements, so taxpayers should confirm the applicable due date for their specific category.

How to File Sales Tax Return on FBR IRIS

Step 1: Login to IRIS

Log in to your FBR IRIS account.

Step 2: Open Declaration

From the IRIS dashboard, go to Declaration.

Select the relevant Sales Tax and Federal Excise Return option, including the voluntary return filing option available in the IRIS workflow.

Step 3: Select the Tax Period

Select the relevant tax year and month/period for which you are preparing the return.

Step 4: Complete Sales Tax Credit

Open the Sales Tax Credit section and enter or load the relevant information. Use the calculation option provided by the system.

Step 5: Complete Sales Tax Debit

Go to Sales Tax Debit and complete the relevant output tax information.

Step 6: Calculate Payable

Open the Payable section and calculate the amount payable according to the information entered.

Step 7: Calculate Head-Wise Payable

Use the Head Wise Payable calculation option where applicable.

Understanding Sales Tax Annexures in IRIS

Annexures are an important part of Sales Tax Return preparation. They help organize sales, purchases, imports, exports, stock and other relevant transaction information.

Annexure C – Sales

Annexure C is used for relevant sales information. The IRIS workflow provides a Load Invoices option for domestic sales invoices for the selected period.

Annexure A – Purchases / Input Tax

Annexure A is used for relevant purchase and input tax information. Available invoices can be loaded, reviewed and claimed where legally allowable.

Annexure B – Import/GD Information

Relevant Goods Declaration information can be loaded and claimed where applicable.

Annexure D – Exports

Annexure D deals with relevant export-related Goods Declaration information where applicable.

Annexure H – Stock

The IRIS workflow provides an option to add relevant stock information and save the required items.

Annexure J – Products

Annexure J allows relevant goods/products to be managed and required information to be entered.

Annexure K

Relevant information and shipment details can be entered under the applicable Annexure K fields.

Annexure E

Applicable information can be entered and calculated under Annexure E.

Input Tax vs Output Tax

Input Tax Output Tax
Sales Tax paid on eligible purchases/inputs, subject to applicable legal conditions. Sales Tax charged or accounted for on taxable supplies made by the registered person.
May be available as a tax credit where permitted. Forms part of the taxpayer's Sales Tax liability calculation.

Input tax should not automatically be treated as allowable in every case. Proper documentation and compliance with applicable Sales Tax provisions are important.

How to Add CPR Payment in FBR IRIS

Once the Sales Tax liability has been calculated and paid, the relevant payment information can be reflected in the return through the payment section.

The IRIS workflow allows taxpayers to search payment information using details such as:

  • CPR Number
  • Amount Code
  • Paid Amount
What is CPR?

CPR stands for Computerized Payment Receipt. Always check that the payment information corresponds to the correct tax period and liability before linking it with your return.

Verification and Final Submission of Sales Tax Return

1. Review Your Return

Check your sales, purchases, input tax, output tax, adjustments, payment and applicable annexures.

2. Check CPR

Confirm that the correct payment/CPR information has been entered.

3. Open Verification

Go to the Verification tab.

4. Enter PIN

Enter the required PIN and use the verification option.

5. Save as Draft

If your return is incomplete, use the draft functionality where available and continue working on it later.

6. Submit the Return

Once the return has been reviewed and verified, submit it through the IRIS system.

Best Practice:

Do not submit a Sales Tax Return without reconciling your sales, purchases, input tax, output tax and payment records.

Common Sales Tax Registration and Filing Mistakes

Maintain your accounting records and tax documents throughout the month so that your Sales Tax Return can be prepared and reviewed on time.
