Voted on wrc.com by thousands of fans globally, Tänak and co-driver Martin Järveoja gained more than 45 percent of the poll to win ahead of Elfyn Evans, Craig Breen and Sébastien Ogier.
Debuting in the Hyundai i20, the Estonian pairing's Monte-Carlo weekend came to a brutal halt on Friday's second leg. Remarkably both driver and co-driver were able to walk away safely following the high-speed accident which resulted in multiple rolls.
When the WRC season moved on to Sweden three weeks later, Tänak and Jarveoja were back competing - putting their Monte fright behind them to finish second behind Welshman Evans.
Only afterwards did Tänak reveal the lingering pain from the crash and how he won a race against time to be fit to compete in Sweden.
Upon learning of his win, Tänak had the following message for his fans: "Thank you everyone for your continued support. 2020 was not an easy ride.
"Generally, with my performance, I can not be too happy but the New Year is already starting and we are ready to go so of course we want to be better and we are looking forward and hopefully we will be able to see you (the fans) on the stages to enjoy rallying together."
Tänak will be back behind the wheel of a Hyundai i20 when the season starts in Monte-Carlo from 23-26 January.
