The British Asian singer-songwriter was recognised in the 'Best Playback Singer (Male)' category for his track from Salman Khan and Kareena Kapoor's Bodyguard.
King said: "It feels great to be nominated for an IIFA in what was my first big year in the Bollywood industry.
"I feel privileged to be nominated for Best Playback singer alongside some of the top vocalists of Indian music today and am honoured that IIFA have recognised me in this category."
This year's awards ceremony will take place in Singapore in June.
King added: "This will be my first time going to Singapore for the awards and being British, I do hope all the Brits vote for me so I can bring the award home."
The London singer has featured on six major Bollywood soundtracks, with songs including 'Dil Gira Dafatan' from Dehli, 'Te Amo' from Dum Maaro Dum, 'I Love You' and most recently 'Aunty Ji' from 'Ek Main Aur Ekk Tu.
King won the Stardust award for 'Best Male Singing Sensation' earlier this year.
Bodyguard was released in August 2011.
