Sales Tax Filing Procedures in Pakistan

Proper sales tax filing is crucial for maintaining compliance and avoiding penalties. This comprehensive guide walks you through the complete sales tax filing process in Pakistan.

Understanding Sales Tax Filing

Sales tax filing involves submitting monthly returns to the Federal Board of Revenue (FBR) detailing your sales, purchases, tax collected, and tax paid. All registered businesses must file returns by the 18th of each month for the previous month's transactions.

Filing Deadlines

Important dates to remember:

• Monthly Return: Due by the 18th of each month
• Tax Payment: Must be paid before or on the filing date
• Late Filing: Penalties apply after the deadline
• Annual Reconciliation: Additional annual statements may be required

Step-by-Step Filing Process

Step 1: Prepare Your Records

Before filing, ensure you have:

• Complete sales records for the month
• All purchase invoices with sales tax
• Records of tax collected from customers
• Records of tax paid on purchases
• Supporting documents and receipts

Step 2: Calculate Output Tax

Output tax is the sales tax you collected from customers on your sales. Calculate this by:

• Summing all sales tax collected on taxable sales
• Including sales tax on services provided
• Accounting for zero-rated and exempt sales separately

Step 3: Calculate Input Tax

Input tax is the sales tax you paid on purchases and business expenses:

• Sum all sales tax paid on purchases
• Include tax on raw materials, equipment, and services
• Ensure all purchases are from registered suppliers
• Verify invoices are valid and complete

Step 4: Calculate Net Tax Payable

Net tax payable = Output Tax - Input Tax

• If positive: You owe tax to FBR
• If negative: You may claim a refund (subject to conditions)
• If zero: No payment required, but filing is still mandatory

Step 5: Log in to IRIS Portal

Access the FBR IRIS portal using your credentials:

• Use your Sales Tax Registration Number (STRN)
• Enter your password and security code
• Navigate to the Sales Tax section

Step 6: Fill the Return Form

Complete the sales tax return form with:

• Total sales value
• Output tax amount
• Total purchases value
• Input tax amount
• Net tax payable or refundable
• Any adjustments or corrections

Step 7: Review and Submit

Before submitting:

• Double-check all figures for accuracy
• Verify calculations
• Ensure all required fields are completed
• Review for any errors or omissions

Step 8: Make Payment (if applicable)

If you have net tax payable:

• Generate payment challan from IRIS
• Pay through designated banks or online
• Keep payment receipt for records
• Update payment details in the return

Step 9: Save Acknowledgement

After successful submission:

• Download and save the return acknowledgement
• Keep a copy for your records
• Maintain supporting documents

Common Filing Scenarios

Scenario 1: Regular Filing

When you have both sales and purchases, calculate net tax and file accordingly.

Scenario 2: No Sales in a Month

Even with no sales, you must file a nil return to maintain compliance.

Scenario 3: Refund Claim

If input tax exceeds output tax, you may claim a refund subject to FBR verification.
