FBR Tax Calculator Pakistan 2026: Sales Tax Rates and Digital Invoice Calculations

Understanding Sales Tax in Pakistan

Sales tax in Pakistan is governed by the Sales Tax Act, 1990 and administered by FBR. The standard rate is 18% on the value of taxable supplies, but numerous exemptions, reduced rates, and additional taxes apply depending on the product, buyer status, and applicable SROs. Correct tax calculation is critical for FBR digital invoicing compliance.

Standard Sales Tax Rate: 18%

The general sales tax rate of 18% applies to most taxable goods. On a digital invoice, this is calculated as:

• Taxable Value: Unit Price x Quantity - Discount
• Sales Tax (18%): Taxable Value x 0.18
• Total: Taxable Value + Sales Tax

Example Calculation

For a supply of 500 KG of chemicals at Rs. 200/KG:

• Taxable Value: 500 x 200 = Rs. 100,000
• Sales Tax: 100,000 x 18% = Rs. 18,000
• Invoice Total: Rs. 118,000

Further Tax

Further tax is an additional levy on supplies to unregistered persons. When your buyer is not registered for sales tax (no NTN), you may need to charge further tax:

• Rate: Varies by SRO (commonly 1-3% of taxable value)
• When applicable: Supplies to unregistered buyers in specified sectors
• On digital invoice: Listed as a separate line in the tax calculation

Extra Tax

Extra tax applies in specific scenarios defined by FBR notifications:

• Supplies of specific goods listed in the Third Schedule
• Luxury items and specified categories
• Rate varies by product category

Advance Tax Under Sections 236G and 236H

Section 236G — Advance Tax on Sales to Distributors

When selling to distributors, dealers, or wholesalers:

• Filer rate: 0.1% of the gross amount
• Non-filer rate: 0.5% of the gross amount

Section 236H — Advance Tax on Sales to Retailers

When selling to retailers:

• Filer rate: 0.5% of the gross amount
• Non-filer rate: 1.0% of the gross amount

These advance tax amounts must be collected and deposited to the government, and should be reflected on the digital invoice for transparency.

Zero-Rated Supplies (0%)

Certain supplies are zero-rated under the Fifth Schedule:

• Exports and supplies against export orders
• Supplies to diplomats and international organizations
• Supplies to registered exporters under specific conditions

Zero-rated means 0% sales tax is charged, but the supplier can still claim input tax credits on purchases related to these supplies.

Exempt Supplies

Exempt supplies are not subject to sales tax at all. Key exemptions include:

• Basic food items (unprocessed)
• Agricultural inputs (fertilizers, pesticides)
• Medicines and medical equipment
• Educational materials

Unlike zero-rated supplies, exempt supplies do not allow input tax credit claims.

Calculating Tax on FBR Digital Invoices

DigitalInvoices.pk automatically calculates all applicable taxes based on:

• Buyer Status: Registered (NTN) vs unregistered (CNIC) determines additional taxes
• Province: Buyer's province for provincial tax considerations

Tips for Accurate Tax Calculations

1. Use updated HS codes: Tax rates are HS code-specific and change with FBR notifications
2. Verify buyer ATL status: Determines advance tax rates (236G/236H)
3. Check SRO applicability: Many items have reduced rates under specific SROs
4. Round correctly: FBR expects amounts rounded to 2 decimal places
5. Match totals: Ensure line item totals sum to the invoice total exactly
