Taxation in the Palestinian territories is a complex system which may involve payment to the Palestinian Authority (PA) and/or Israel in the context of the Israeli–Palestinian conflict. In 2005 the Palestinian Authority collected approximately $34 million per month from taxes and other charges, and Israel collected about $75 million per month in tariffs on foreign imports and value added taxes (VAT) on Israeli goods and services and on average kept about $15 million for the payment of water and power bills of Palestinians, while forwarding the other $60 million to the PA.[1] Israeli collected funds account for about two-thirds of the authority's self-generated revenue.[2] Since the 2006 Palestinian legislative election, Israel has regularly withheld the taxes it owes the Hamas-led Palestinian Authority.[1][3][4]
