In the early 1980s, direct taxes accounted for about 15% of government revenues. The share provided by indirect taxes declined from 42% to 30%, as revenues from natural gas and state enterprises played an increasing role in government finance. Tax collection, never an effective source of revenue in rural areas, was essentially disabled by the disruption caused by fighting and mass flight. Under the Taliban, arbitrary taxes, including those on humanitarian goods, were imposed.
In 2005 the government introduced an income (or wage) tax. Employers with two or more employees were required to pay 10% on annual income over about $3,500 and 20% on income over about $27,000.
