For Maryland, you can itemize on your Maryland tax return if you itemize on your federal return, but you do NOT have to itemize if the standard deduction gives you a greater tax benefit.
BTW, since you are filing two state returns, credits for taxes paid in the other state will probably apply. For this reason, it would probably be better if you have a tax professional prepare these returns to make sure that you do not pay taxes to both states on the same salary.
