Pakistan's tax-to-GDP ratio of 9.5 per cent is among the lowest in the world and the government is under pressure from foreign donors and lenders, including the International Monetary Fund (IMF), to increase collection to boost the struggling economy.
Revenue authorities say they have identified about a quarter of a million new taxpayers who they project will add around 14 billion rupees (USD 140 million) to government coffers.
Currently less than one per cent of Pakistanis pay income tax and the government collected just USD 8 billion in total income tax in the 2013-14 fiscal year -- barely enough to cover just the country's defence expenditure of USD 7 billion.
The finance ministry is aiming to boost the tax-to-GDP ratio to 15 per cent in the current fiscal year ending June 30.
"We are collecting information from the vehicle registration authority, car manufacturers, utility companies, telecom companies and property registration offices and tracing people who are not paying any tax," FBR spokesman Shahid Hussain told AFP.
The data is used to generate profiles of potential taxpayers, after which demands are issued for them to pay income tax.
"FBR has already issued notices to 261,250 potential tax payers," Hussain told AFP, adding that that new taxpayers have paid 570 million rupees since the crackdown started.
The FBR has taken punitive measures against some "chronic defaulters", freezing nearly 300 bank accounts, seizing more than 100 vehicles, putting 78 properties up for sale and issuing arrest warrants in 40 cases.
