Welcome to DMA

Since 1972, DMA’s professionals have served our North American clients by partnering with them to solve their corporate tax problems. Our practice focuses on seven key areas of corporate taxation: property tax, sales/use & commodity tax, state income & franchise tax, tax technology, crown royalties, medical device excise tax, and unclaimed property tax. We assist companies with managing their compliance obligations, enhancing the efficiency of tax administration with technology, and minimizing their taxes.

DMA is proud to be employee-owned since 1994. Our clients – our partners – reap the benefits of DMA’s ownership culture.  DMA employee-owners ensure that your experience with DMA exceeds expectations by focusing on our core values of integrity, teamwork, flexibility, continuous improvement and creativity, and exceptional client results. DMA’s professionals work with you as an extension of your tax department, and take great pride in meeting your most critical needs with creativity, timeliness, and dedication.
