Plaxico Burress pled guilty to tax evasion in New Jersey Monday -- but will NOT spend one second behind bars ... TMZ Sports has learned.
As we previously reported, officials in Mercer County, NJ charged the ex-NFL star with two tax crimes for failing to pay $48k in state taxes ... each count carried a maximum 5 year prison sentence under NJ's new ultra-strict tax laws.
But Plax's rep tells TMZ Sports ... Burress struck a plea deal with prosecutors in which he agreed to plead guilty and in exchange he'll serve no jail time.
Instead, Plaxico will do community service and pay penalties -- in addition to repaying the money he initially owed. In fact, we're told Plax has already paid off his financial debt.
