Better Exposed Filters
I tried on my local with 


drupal 7.30-dev 
views 7.x-3.7 
better exposed filter 7.x-3.0-beta4


Added term reference field in article content type. Created a view, added this term reference field as exposed filter i was able to get the checkboxes for tid.

Make sure the term reference field setting is set to "Dropdown" and Use Ajax options is set to "yes".




After setting term reference field setting to "Dropdown" i was able to see the "Checkbox/radio buttons" options in better exposed filter setting.
