In October 2012 the Canada Revenue Agency (CRA) will be releasing a revised Form T661, Scientific Research and Experimental Development (SR&ED) Expenditures Claim, to accommodate the legislative changes proposed in the March 2012 federal budget that will be coming into effect starting January 1, 2013.
This revised version of Form T661(12) (revision code 1201) will be effective as of its publication date. We encourage you to start using the new form as soon as it is available.
You can submit the T661(11) version of the form until December 31, 2012. Starting January 1, 2013, we will accept only the T661(12) version of the form for all tax years.
