Simonsgroup was founded on a simple belief: financial decisions should feel clear, not complicated. Since 2010, we’ve helped businesses and individuals move beyond filing into confident, strategy-driven decisions.
Too many tax firms treat clients like transactions—rushing to prepare returns once a year and disappearing until next April.
We built Simonsgroup to be different. We take the time to understand your business, your goals, and your future—so every decision is intentional, not reactive.
Founder, Simonsgroup Tax Advisory
Tim founded Simonsgroup in 2010 with a clear mission: to bring clarity and strategy to tax advisory—not just compliance. With decades of experience in accounting and tax planning, Tim has helped hundreds of business owners, professionals, and investors take control of their financial futures.
Tim's approach is rooted in education and partnership. He believes that when clients truly understand their numbers, they make better decisions. That’s why every engagement at Simonsgroup includes not just expert execution, but clear explanation.
Based in Washington, DC, Tim works closely with each client to develop customized strategies that align with their goals—whether that’s minimizing tax liability, cleaning up prior-year issues, or building systems that support long-term growth.
We act in your best interest—always. Honest advice, transparent communication, and no hidden agendas.
We believe informed clients make better decisions. We explain the “why,” not just the numbers.
Clear structure. Clear reporting. Clear next steps—so you always know where you stand.
Strategy only matters if it’s usable. Every recommendation is built to be practical and implementable.
