Hey does anyone know if Wharton offers an MS in taxation?

Does wharton or harvard offer an MS in taxation? I tried to google it all over, but I just keep bumping into MBA programs for those schools and I was wondering if there is a site where they compare MBA to MS because even though I'm 90% sure i want an MS in taxation i wanted to make certain of it up to 100%, but I couldn't find any comparisons of MBA to MS.
