GREEK officials put the final touches yesterday on an overhaul of the country's ineffective tax system - part of their urgent effort to fix a debt crisis that has shaken the entire eurozone.

The government has pledged to fight endemic tax evasion and increase taxes on the rich, as well as taxes on fuel, cigarettes and alcohol.

Finance Minister George Papaconstantinou says a new tax bill to be presented this week will expand the top 40 percent tax bracket to incomes below the current 75,000 euros (US$102,000) threshold.
