Jason Huggett appeared at Worthing Magistrates Court last week.
He admitted three charges of failing to notify changes in his circumstances to both Chichester District Council and the Department for Work and Pensions, and providing false documents to the council.
He was ordered to undertake 100 hours of community work and to pay £400 towards costs.
Chichester Council and the DWP aims to recover all the money that Mr Huggett falsely claimed.
