The 23-year-old is one of 12 golfers to feature on the list which profiles the wealthiest sportspeople in Britain and Ireland.
Last year, McIlroy made it onto the list of wealthy young sportsmen, aged 30 and under, with a £7m fortune.
Sir Nick Faldo topped the 2012 Golf Rich List and is believed to be worth a massive £34m.
Meanwhile, fellow NI golfer Graeme McDowell appeared just above McIlroy on the richest golfers' list with a wealth of £12m.
Darren Clarke and Lee Westwood saw their golf fortunes fall by £6m after they lost money by jointly buying a 10-seater Challenger 601 jet at the top of the market and selling during the slump.
Manchester United's Sir Alex Ferguson is the wealthiest football manager on the Sunday Times list.
His fortune is up £5m on 2011 and now stands at £32m.
