Jack Letts' father John, 55, and mother Sally, 53, have been charged with three counts of entering or becoming concerned in an arrangement to make money available, knowing or having reasonable cause to suspect that it may be used for terrorism.
They will appear at Westminster Magistrate's Court in London on June 9.
The couple had said the money was for their 20-year-old son to buy a new pair of glasses when they were arrested earlier this year.
The couple have said there was no evidence their son had become an ISIS fighter and claimed the police have "put two and two together and made 10".
"He has the freedom to practice whatever he wants, that's British values. It's so unfair, but if there is any evidence that he's done anything violent, if anyone can prove any of these allegations... If you can show me any of that I'll be the first to believe it and I'll be the first to report it,"Jack's mother Sally said.
