Can my wife and i use the same address and both use married filing separately

Why aren't you filing Joint?  Joint is usually the best way to file.  You can lose several credits if you file separately. See …….

Yes, but you will generally pay more combined tax on separate returns than you would on a joint return due to special rules.

Please see this IRS link for more information regarding the special rules: https://www.irs.gov/publications/p17/ch02.html#en_US_2016_publink1000170777
