In Cebu, compliance was 74.9 percent, 77.3 percent in Davao del Sur, and 88.6 percent in Laguna.
In the provinces of Negros Oriental, Nueva Vizcaya and Pangasinan, the monitored cigarette packs had no tax stamps.
Since late 2014, the Bureau of Internal Revenue (BIR) has been implementing the Internal Revenue Stamps Integrated System (Irsis) on tobacco products, aimed at ensuring collection of correct excise taxes.
The BIR under then Commissioner Kim S. Jacinto-Henares tightened its monitoring of cigarette firms’ tax payments through Irsis, especially after tens of thousands of unstamped packs were confiscated in provinces such as Batangas and Nueva Ecija last year.
The BIR also intensified its monitoring not only of cigarettes products but also their manufacturers and sellers. The country’s biggest tax-collection agency had conducted on-the-spot surveillance of tobacco products in production and storage facilities as well as in retail outlets.
