Now aged 15, the boy who comes from a Turkish background, is accused of "participating in a terrorist group". His case will be heard at a Sankt-Polten court, west of the capital.
Arrested at school in October 2014, police said the boy has admitted he was trying to make a bomb, and that he was planning to plant it at one of Vienna's main stations.
Investigators said they found IS propaganda images on his computer, phone and video game console.
The teenager has also admitted he wanted to travel to Syria to join the IS's ranks. He broke his bail conditions and tried to flee in January with a 12-year-old friend, with both apparently trying to reach the war-torn country.
Because of his age, the maximum sentence he could face is five years in prison.
According to unconfirmed press reports, IS had promised the teenager 25,000 euros (USD 28,000) to commit the Vienna attack.
Vienna says at least 200 people from Austria, including women and children, have travelled to Syria and Iraq, where the IS controls vast swathes of territory and commits horrific abuses.
