The Canada Revenue Agency (CRA) has revised the SR&ED T661(13) form to accommodate the legislative changes coming into effect on January 1, 2014, and to ensure consistency with the consolidated SR&ED policy documents released in December 2012. The previous T661(12) version of the form can be submitted until December 31, 2013, but starting on January 01, 2014, the CRA will accept only the T661(13) version of the form for all tax years.
