Is there a refinance county tax stamp charge for Frederick county Maryland?

Yes - it is $12.00/thousand refinanced, on your primary residence.

In simple terms:

In other words, if you have a $200,000 deed of trust that will pay off a $100,000 deed of trust, there is a $100,000 difference, so 100 X $12 = $1200 state recordation tax.

If however you are getting an equity line for $50,000 and are not paying anything mortgage off, then it is 50 x $12 = $600.00.
