Muhedin Ali, of Chesterton Road, west London, is accused of assisting one of the suspects in the attempted bombings, Hussain Osman, to evade arrest.
He is also charged with failing to disclose information about Mr Osman, and will appear before magistrates in central London on Saturday.
The failed attacks took place two weeks after suicide bombers killed 52 people.
Mr Osman, 27, is charged with offences including the attempted murder of Tube passengers at Shepherd's Bush and conspiracy to murder.
Three other men face the same charges as Ethiopian-born Mr Osman, in relation to an attempt to bomb three Tube trains and a bus.
They are Ibrahim Muktar Said, Yassin Hassan Omar and Ramzi Mohamed. A fifth man is charged with conspiracy to murder.
Seventeen people have been charged in total, mostly with offences of helping suspects to evade arrest or withholding information from police.
The principle defendants are expected to stand trial in the autumn.
The charges faced by Mr Ali are:
- that between 21 July and 28 July he had information which "he knew or believed might be of material assistance in securing the apprehension, prosecution or conviction of Hussain Osman in the United Kingdom" and that he failed to disclose it, contrary to Section 38B of the Terrorism Act 2000.
- that "without lawful authority or reasonable excuse", he assisted Hussein Osman to evade arrests "knowing or believing" that Osman had committed offences of attempted murder, conspiracy to murder and offences contrary to the Explosive Substances Act on July 21.
The failed 21 July attacks took place two weeks to the day after four suicide bombers killed 52 passengers on the London transport network.
