The pair appeared to exchange angry words on stage after shaking hands at the end of their semi-final match at Alexandra Palace, which Taylor won.
Afterwards the 52-year-old apologised to the Dutchman and expressed his disappointment at his actions, adding he would be happy to feel the full force of any disciplinary action.
Taylor had claimed Van Barneveld's handshake had been too strong.
A PDC spokesman confirmed tonight: "As with any incident like this, it has been referred to the Darts Regulation Authority.
"They will decide if there's been any breach of the rules and whether there should be a punishment."
Taylor went on to win his 16th world title by beating Van Barneveld's compatriot Michael van Gerwen in the final.
Proteas crush Kiwis
CRICKET: South Africa finalised an innings and 27-run hammering of New Zealand midway through the third day of the opening Test in Cape Town.
The Proteas' fast-paced success, their fifth biggest Test win over New Zealand, was all but secured after they bowled the tourists out for just 45 on the opening morning.
The Black Caps were never likely to recover from slumping to their lowest ever total against South Africa, beating the 79 they managed at Johannesburg in 1954, and only Dean Brownlie's maiden century stretched the contest beyond halfway of the scheduled five days.
Victory ensured South Africa, the top-ranked Test nation, will go an 11th series without defeat before the second and final match in Port Elizabeth begins on January 11.
