Morley, a former Labour environment minister, pleaded guilty last month to claiming more than £30,000 in bogus mortgage payments.
He entered two guilty pleas for false accounting relating to his home in Winterton, near Scunthorpe, North Lincolnshire, between 2004 and 2007.
Morley was sentenced at London’s Southwark Crown Court.
A Labour Party spokesman said: “Elliot Morley had already been suspended from the Labour Party and following his custodial sentence he has now been excluded from the party.”
Morley, who appeared flushed throughout the hearing, showed no emotion as the sentence was delivered.
