Simonsgroup was founded on a simple belief: financial decisions should feel clear, not complicated. Since 2010, we’ve helped business owners and professionals move beyond reactive tax filing into confident, strategy-driven decisions—locally in Washington, DC and nationwide.
Too many tax firms treat clients like transactions—rushing to prepare returns once a year and disappearing until next April. That reactive model leaves business owners and professionals overpaying, under-planning, and unsure how to improve. We built Simonsgroup to be different. As a strategy-driven tax advisory firm, we take the time to understand your business, your income, and your long-term goals—so every financial decision is intentional, proactive, and aligned with the future you’re building.
