The intent to charge Mr Abhisit and his former deputy was announced after a meeting of Thailand's Department of Special Investigation (DSI), police and Thai prosecutors.
"The tripartite meeting has decided to charge former prime minister Abhisit Vejjajiva and former deputy Suthep Thaugsuban under article 288," said DSI chief Tarit Pengdith, referring to the murder provision under Thailand's criminal code.
In September, an inquest found that taxi driver Phan Kamkong was shot and killed by Thai soldiers during political violence around anti-government Red Shirt protests in 2010.
An earlier court ruling found the taxi driver was killed in a volley of army bullets when he ran out of an apartment building to see what was going on after hearing gunfire.
Mr Abhisit and Mr Suthep are expected to be questioned next week.
About 90 people were killed and nearly 1,900 were wounded in a series of street clashes between demonstrators and security forces, which culminated in a bloody military crackdown.
Two foreign journalists were among those killed.
Until now, no government or military officials had faced charges over the deaths.
Mr Abhisit, who oversaw the crackdown, has insisted the protest leaders should accept responsibility and said his government had no choice but to take tough action.
Red Shirts, mostly supporters of ousted ex-premier Thaksin Shinawatra, have raised accusations of double standards over the prosecutions of 24 of their leaders on terrorism charges for their part in the rallies.
Rights campaigners have said both the protesters and the authorities of the time should be held accountable.
