Von Fischer and Collinson became joint directors of BIFA in 2006 and between them have produced the Awards since 2001. The Awards were founded by Raindance in 1998 and will return to Raindance, with a new structure to be announced later this year.
Von Fischer and Collinson said: "It has been a tough decision to move on from BIFA but we are ready to take on new challenges and excited about embarking on a fresh chapter in our careers. We are extremely proud of how BIFA has developed over the years and have been fortunate to have the incredible support of the film industry, our advisory committee, our partners and a loyal team who have helped to raise the profile of BIFA and without whom we could never have pulled off so many fantastic awards ceremonies.
"For now we are currently focused on the selection process and it certainly looks as if 2014 will be a year to remember."
Raindance and BIFA founder Elliot Grove, added: "Tessa and Johanna have become synonymous with BIFA. Through their great work the awards have risen to new heights. We look forward to working with the industry and stakeholders to develop the next era for the British Independent Film Awards."
Agency GSP Events has worked on the event for the last 13 years, and will be devising this year's ceremony, to be held at Old Billingsgate. This year's awards will be sponsored by Moet & Chandon for the fifth year running.
