The Sindh government has introduced financial penalties of up to Rs1 million for individuals and companies involved in designing, developing, customising or supplying invoicing software that enables the issuance of invoices in violation of provincial sales tax laws. The new provision has been enacted through the Sindh Finance Act, 2026, forming part of the provincial government’s wider effort to improve tax compliance and reduce evasion linked to non compliant invoicing systems.
Under the amended law, any person who designs, develops, customises or supplies invoicing software that facilitates the issuance of invoices which do not comply with sub rule 1 of Rule 29 of the Sindh Sales Tax on Services Rules, 2011, or Rule 6 of the Sindh Sales Tax Special Procedure (Online Integration of Business) Rules, 2022, will now be liable to financial penalties. The legislation prescribes a minimum penalty of Rs100,000, which authorities may increase to as much as Rs1 million depending on the nature and seriousness of the violation involved. The provision applies broadly to anyone involved in the software supply chain rather than only to the businesses ultimately using the invoicing systems, extending accountability to developers and vendors who build or customise such tools for clients operating in the province.
The amendment is designed to ensure that invoicing software used by businesses across Sindh fully complies with requirements set by the Sindh Revenue Board governing electronic invoicing and the online integration of taxable businesses. Sindh has been working to bring more transactions into a documented and traceable system in recent years, and this latest step targets a specific gap in enforcement, since previous penalties largely applied to businesses that failed to integrate their systems rather than to those who built software specifically capable of bypassing statutory requirements. Tax experts said the measure is expected to discourage the development and distribution of software capable of generating invoices that sidestep these rules, thereby improving transparency, reducing opportunities for tax evasion, and improving overall documentation of taxable transactions across the province.
The latest amendment forms part of a wider package of tax reforms introduced through the Sindh Finance Act, 2026, reflecting the provincial government’s continued focus on digital tax administration and revenue collection through improved enforcement mechanisms. Businesses operating in Sindh that rely on third party invoicing software will now need to confirm that their systems are fully aligned with Sindh Revenue Board requirements, since liability under the new provision extends to the developers and suppliers of such tools and not only to the businesses using them. The move reflects a broader pattern across Pakistan’s provinces, where digital invoicing and electronic tax integration have become central pillars of efforts to widen the tax net and reduce reliance on manual, undocumented transactions across various sectors of the economy.
