Yes, regardless of where you live, if you purchase a car in MA you must pay the 6.25 percent sales tax in MA within 10 days if you're going to register in MA or within 20 days if you're going to register it anywhere else. Use MA DOR Form ST-7R Motor Vehicle Certificate of Payment of Sales or Use Tax.
