People who hide their money overseas to avoid paying tax face bigger fines and could be jailed more easily under government plans to fight tax evasion. To prosecute at present, tax officials must prove a person holding income offshore has intended to evade tax. But under a new criminal standard officials would only have to show money was taxable and undeclared. Chancellor George Osborne said the changes would mean there was "no safe haven" for those evading tax. But Labour said the government was "failing to tackle tax avoidance and evasion". A consultation will be held to let the public have their say on the plans.
