As 1053857 stated, if the taxiway holding position line marks the entrance to the movement area, then yes, you need ATC clearance to proceed.
If, however, you're already taxiing and encounter the combination dashed/solid lines, you may proceed through the intersection so long as the dashed lines are the ones facing you. "Dash through the dash; stop at the solid."
Do you have an airport diagram with labels to show the intersection to which you are referring?
