Having interviewed a variety of people who have lived, or are still living under Daesh rule, the newspaper outlined the Islamic zakat tax, which is collected at a rate of 2.5 percent of capital owned by people with sufficient income, loot markets, customs duties, salary and remittance taxes as major revenue sources for the terrorists.
With revenues of $20 million from farming and $23 million from salary taxation in Iraqi's Mosul alone, Daesh now benefits from trade with Turkish suppliers who have been contributing $140 million a year in duties, according the newspaper's research.
The Daesh terrorist group has been in control of large areas of Syria and Iraq since 2014. The violent religious extremist group is outlawed in many countries including Russia, where it is classified as a terrorist organization. Last week, Russia presented evidence of oil smuggling by the group across the border with Turkey.
