The Bureau of Internal Revenue (BIR) is now focusing its target audit on business establishments suspected to be issuing bogus receipts and invoices to their customers. BIR Commissioner Romeo D. Lumagui, Jr. said such modus has been causing the government to lose billions of pesos annually. Lumagui said an initial list of these business operators has been consolidated  based on fake sales papers seized during the raid of the contraband factory in Eastwood, Quezon City in December last year. The confiscated and spurious receipts and invoices bore the names of traders operating in Metro Manila and other urban centers across the country. "We are not only targeting the printers and distributors, but the buyers and users as well as their accountants who assist them in manipulating their financial records to reduce tax payments, " Lumagui said. As the income tax filing  ends on April 17, the BIR chief warned buyers and users of bogus receipts to stop using them, or "you will be spending more than paying correct taxes." He said they will be prosecuted in court for tax evasion and which carries the penalty of jail time.
