She was suspended from competition by the Athletics Integrity Unit in January 2021 after being charged with 'tampering of doping control'. She had missed three out-of-competition drug tests.
The American won the gold medal in the women's 100 m hurdles in Rio Games. The 29-year-old is also a former world champion.
The Athletics Integrity Unit (AIU) announced the ban on Friday.
The AIU, however, said that she can still take part in the US trials for the Tokyo Olympics later this month while she appeals the ban, which is backdated to August 15, 2020.
Her appeal is expected to be heard before the Olympics begin on July 23.
AIU said she had been banned for “tampering within the results management process”.
It was her second doping violation after she missed the 2017 World Championships while serving a one-year ban for missing three drug tests.
McNeal had in February protested her innocence.
“The system is pretty messed up if you ask me but that’s another topic for another day,” she said in an Instagram post.
She added: “As far as my situation goes, I am still me! Very clean, very honest and transparent.
“Once all of this blows over I will provide more details of what’s actually going on.”
