Smith is currently in the midst of his third series as the Time Lord and he has revealed to the Radio Times that he has no desire to vacate the role.
"We've got Doctor Who's 50th anniversary coming up in November 2013, and one assumes there'll be another Christmas special after that, and I'd hope to be part of it," he explained.
The actor continued: "I take each year as it comes. All good things come to an end, but my mum is aghast at the thought of me ever not being the Doctor. The show is the star and will continue without me.
"I'm committed to it next year and will sit down with Steven Moffat and see where we go from there. I've no immediate plans to leave. I'm around for a whole year and that's a long time."
Smith's commitment to Doctor Who means he will be present throughout the show's 50th anniversary next year.
Doctor Who debuted on BBC One on November 23, 1963 with William Hartnell as the First Doctor and Carole Ann Ford, Jacqueline Hill and William Russell as the first companions.
The current 11th Doctor is to be joined by a new companion played by Jenna-Louise Coleman in the upcoming Christmas special 'The Snowmen', which also stars Richard E Grant.
'The Snowmen' airs at 5.15pm on BBC One in the UK and at 8pm on BBC America.
