About David G Mayer
David G Mayer Jr earned advanced legal training before opening his own practice. He holds a Master of Laws in Taxation from the University of Missouri–Kansas City School of Law, completed in 2012. He also earned a juris doctor degree from the University of Nebraska–Lincoln earlier in his training. The LL.M. provided specialized coursework in federal taxation, tax planning and compliance that informs his day-to-day work.
Mayer began his legal career after law school and built experience across matters that intersect tax, business and estate planning. Over time he moved into private practice where his academic background in taxation became a practical asset. Colleagues describe him as methodical; clients expect careful attention to the numbers and to legal detail. He combines technical tax knowledge with courtroom and transactional experience developed through routine client work.
He is admitted to practice in Iowa and Wisconsin and maintains current memberships in professional associations. Those admissions allow him to represent clients in matters governed by state rules in both jurisdictions. He has handled matters for individuals and businesses that require coordination between state and federal tax concerns, and he has advised on tax implications of business structures and transfers.
Mayer’s work blends counseling and advocacy. He drafts agreements and tax-sensitive business documents, prepares filings, and negotiates with taxing authorities when disputes arise. He also prepares estate-related documents where tax consequences are a significant factor. The LL.M. training supports technical research and analysis on complex transactions and regulatory issues.
Outside of client work, Mayer keeps current on changes in tax law and regulation. He attends continuing legal education and engages with peers through association membership. That ongoing study helps when new rules require rapid adjustments in client planning and compliance strategies.
He is principal at Mayer Law, LLC, where he manages a small practice that handles a mix of tax, business and estate matters for clients in Iowa and Wisconsin. His practice concentrates on applying specialized tax knowledge to practical legal problems at Mayer Law, LLC, where he now practices.
