Craig Mackinlay has been charged with declaring false election expenses in 2015
The 50-year-old Tory candidate for South Thanet – who stood against Nigel Farage – is accused of two counts of falsely declaring expenses.
His agent, Nathan Gray, 28, and party organiser Marion Little, 62, have also been charged with offences under the Representation of the People Act 1983.
They are due to appear at Westminster Magistrates' Court on July 4.
Mr Mackinlay is running for the South Thanet again in next Thursday's General Election.
The Conservative Party has denounced the charges, saying they stem from "politically motivated and unfounded complaints".
A spokesman, said: "The legal authorities have previously cleared Conservative candidates who faces numerous politically motivated and unfounded complaints over the Party's national Battlebus campaigning.
"We continue to believe that this remaining allegation is unfounded.
"Our candidate has made clear that there was no intention by him or his campaigners to engage in any inappropriate activity.
"We believe that they have done nothing wrong, and we are confident that this will be proven as the matter progresses.
"The individuals remain innocent unless otherwise proven guilty in a court of law.
"There is a broad consensus that election law is fragmented, confused and unclear, with two different sets of legislation, and poor guidance from the Electoral Commission.
"Conservatives are committed to strengthening electoral law to tackle the real and proven cases of corruptiong that were exposed in Tower Hamlets in 2015."
