How much input tax does a Tier-1 retailer lose if its outlets are not integrated?

What does the law say?

Section 8B of the Sales Tax Act, 1990 limits how much input tax a registered person can set against output tax. Subsection (6) is aimed at Tier-1 retailers. If a Tier-1 retailer “does not integrate his retail outlet” as required, during a tax period or any part of it, “the adjustable input tax for whole of that tax period shall be reduced by 60%”.

Three features of the wording matter:

• Any outlet. The trigger is a single retail outlet that is not integrated.
• Any part of the period. The words “or part thereof” mean the outlet need not be out of integration for the full month.
• The whole period. The reduction is applied to adjustable input tax for the whole tax period, not to a daily or per-outlet share.

A tax period is one month under section 2(43), unless the Board specifies otherwise. So in practice the cut is applied month by month.

How does it work in practice?

A registered Tier-1 retailer pays sales tax at the rate that applies to the goods it sells, as section 3(9A) provides, and reduces its output tax by the input tax it paid on purchases. Section 8B(6) shrinks that input tax figure for any month in which an outlet was not integrated.

The integration duty itself is in the proviso to section 23(6): from the date and in the manner the Board prescribes, all Tier-1 retailers shall integrate their retail outlets with the Board’s computerized system for real-time reporting of sales.

Section 8B has other limits that can apply in the same month:

• The 90% cap in section 8B(1). Input tax above 90% of output tax is not adjustable, except for fixed assets or capital goods. A proviso added by the Finance Act, 2026 lets the Board, by notification, reduce or enhance this limit based on compliance with POS and other electronic systems.
• Board-set limits in section 8B(4). The Board may prescribe other limits or use automated risk management to defer input tax.

Worked example (illustrative figures)

A home appliances retailer in Islamabad is a Tier-1 retailer with three outlets. In the September tax period, one outlet’s POS was not integrated for five days. The other two were integrated all month. All figures are invented.

Step	Working	Amount
Output tax for September	Illustrative figure	Rs. 1,800,000
Input tax paid on purchases	Illustrative figure	Rs. 1,200,000
90% cap under section 8B(1)	90% x Rs. 1,800,000	Rs. 1,620,000
Input tax within the cap	Rs. 1,200,000 is below Rs. 1,620,000	Rs. 1,200,000
Reduction under section 8B(6)	60% x Rs. 1,200,000	Rs. 720,000
Adjustable input tax	Rs. 1,200,000 - Rs. 720,000	Rs. 480,000
Sales tax payable	Rs. 1,800,000 - Rs. 480,000	Rs. 1,320,000

Had all three outlets been integrated all month, the tax payable would have been Rs. 1,800,000 - Rs. 1,200,000 = Rs. 600,000. The five-day gap at one outlet costs Rs. 1,320,000 - Rs. 600,000 = Rs. 720,000 of extra tax for the month, before any penalty.

In this example the input tax sits below the 90% cap, so the order in which the two limits are applied makes no difference. The Act does not say which comes first where input tax exceeds the cap, and this page does not settle that.

What if the outlet stays non-integrated for several months?

The reduction applies to each tax period in which an outlet was not integrated for all or part of the period. Separately, serial 25A of the section 33 table imposes penalties of Rs. 500,000, Rs. 1 million, Rs. 2 million and Rs. 3 million for successive defaults, and the premises can be sealed.

What if the retailer has no input tax that month?

Then there is nothing for section 8B(6) to reduce. The penalty and sealing provisions still apply to the failure to integrate.

Common mistakes

• Reducing only the outlet’s share. The text reduces adjustable input tax “for whole of that tax period”.
• Thinking a few days do not count. “Part thereof” covers any part of the period.
• Assuming the reduced amount carries forward. The carry forward in section 10(1) refers to input tax not adjustable under section 8B(1). Section 8B(6) is silent on carry forward.
• Reading 60% as the amount you keep. The input tax is reduced by 60%, so 40% remains adjustable.

What to check in the official text

Section 8B(6) still refers to integration “in the manner as prescribed under sub-section (9A) of section 3”. In the edition amended to 30 June 2026, the proviso to section 3(9A) is shown as omitted by the Finance Act, 2025, and the integration duty now appears in the proviso to section 23(6). The Act has not updated the cross-reference, and this page does not resolve what effect that has. Also check any Board notification under the new proviso to section 8B(1) that changes the input tax limit for POS compliance; such notifications are not held on this site.
