Introduction
To enhance transparency and reduce tax evasion, the Federal Board of Revenue (FBR) has introduced Digital Invoicing Integration under the Sales Tax Rules, 2006. This system facilitates real-time reporting of B2B and B2C transactions by integrating business invoicing systems with FBR’s central database.
Digital integration is more than just compliance—it represents a strategic move toward a transparent, efficient, and digital tax ecosystem.
Initially implemented in February 2024 for FMCG manufacturers, importers, and wholesalers, FBR expanded this requirement on 22 April 2025 through S.R.O. 709(I)/2025 to cover all sales tax–registered persons (corporate and non-corporate).
Key Deadlines:
Corporate Entities: Until 1 May 2025 (extended to 1 July 2025)
Non-Corporate Entities: Until 1 June 2025 (extended to 1 August 2025)
This mandate now requires real-time generation, validation, transmission, and archiving of e-invoices via FBR’s Invoice Management System (IMS).
Legal Basis
FBR’s Digital Invoicing Integration is governed by:
Section 50 of the Sales Tax Act, 1990
Chapter XIV-A (Rules 150Z to 150ZH) of the Sales Tax Rules, 2006
This legal framework mandates that certain categories of taxpayers issue digital tax invoices and integrate with FBR’s system.
