It entirely depends on what your sentence is. Usually there will be no comma, for example:
'This is the happiest day of my life.'
'This was definitely not what I was expecting.'
'This meat is too tough for me to eat.'
In constructions like examples 1 and 2 above, there will be a comma if 'this' is separated from the verb that follows it, for example:
'This, the so-called happiest day of my life, is turning into a disaster.'
'This, which was supposed to be making my life easier, is causing me extra work.'
Remember that a written comma normally corresponds to a spoken pause. Say your sentence aloud and see if you would naturally pause after 'this'. For the constructions illustrated above, note that the commas come in pairs, because they act as parentheses.

You can put a comma before or after just about any word if the sentence structure requires it. If the sentence structure does not require it, it may be permissable to use a comma to assist in clarity and avoid confusion. Otherwise, don't use a comma. Have I confused you yet? Using a comma does not depend on the word, it depends on the structure of the sentence.
