The song was written by group members Siobhán Donaghy, Mutya Buena and Keisha Buchanan in collaboration with Cameron McVey, Jony Lipsey, Felix Howard and Matt Rowe, and produced by McVey, Lipsey and Paul Simm. "New Year" is a pop and R&B ballad with influences of soul and alternative rock. It features acoustic instrumentation, and the lyrics describe the experience of breaking up on Christmas Day.

Critics praised the song for its seasonal nature and the group's performance. Upon release, it charted at number twelve in the United Kingdom and number twenty-five in Ireland. To promote the song, a music video was directed by Alex Hamming and filmed in London, England. On 31 December 2012 the trio performed "New Year" at a New Year's Eve party in London, under their new group name Mutya Keisha Siobhan.

British girl group the Sugababes were formed in 1998 by Siobhán Donaghy, Mutya Buena and Keisha Buchanan. Donaghy and Buena first met during an a cappella gig, where they heard each other sing and later performed a duet. The duo decided to work together on a new song, and while they were in the studio, Buchanan came to visit her friend Buena. Donaghy's manager, Ron Tom, concluded that the trio were to join together as a band, known as the Sugababes. They later signed to London Records and began writing songs for their debut album One Touch.
