Simonsgroup Tax Advisory was founded in 2010 with a simple belief: financial decisions should feel clear, not complicated. We help business owners, professionals, executives, and investors move beyond reactive tax filing toward proactive tax planning and confident financial decisions. Based in Washington, DC, we serve clients throughout the DC, Maryland, and Virginia area as well as clients nationwide.
Many tax firms focus primarily on preparing returns and meeting filing deadlines. Simonsgroup takes a different approach. We work with business owners, professionals, and investors throughout the year to understand their financial position, identify planning opportunities, and make informed decisions before tax deadlines arrive.
Our goal is simple: provide clear, proactive tax advisory that connects today’s financial decisions with your long-term goals.
Founder, Simonsgroup Tax Advisory
Tim Simons founded Simonsgroup in 2010 with a mission to bring greater clarity and strategy to tax advisory. With decades of experience in accounting and tax planning, Tim works with business owners, high-income professionals, executives, and investors facing complex tax situations, business structures, and long-term financial decisions.
His approach goes beyond tax return preparation. Tim helps clients understand how their financial decisions can affect future tax outcomes, identify planning opportunities, and build a more proactive approach to their taxes.
