The penalty was imposed on Maria Lagoda at a Proceeds of Crime Act hearing at Peterborough Crown Court.
Last year she and her husband, Peter Lagoda, a Cambridgeshire county councillor, admitted between them a number of benefit fraud offences.
Mrs Lagoda was ordered to pay the council £23,075 in compensation within six months or be jailed for 10 months. Mr Lagoda was told he must pay £1,950, also within six months, or spend 30 days in prison.
Last March they were each given a 12-month community order after admitting between them a number of benefit fraud offences in order to claim more than £25,000 in extra benefits over two years.
Cllr Lagoda represents Wisbech South on Cambridgeshire County Council.
Police investigating the murder of Wisbech pensioner Una Crown are looking into new information following a fresh appeal.
Last week marked the two-year anniversary since 86-year-old Mrs Crown’s body was found at a bungalow in Magazine Lane.
Detectives made a renewed appeal for information.
A police spokesman said: “As a result of the fresh appeal, we have received two different pieces of information from members of the public which we are now looking into.”
A £10,000 reward from Crimestoppers is still on offer for information leading to an arrest.
Call police on 101.
