Meet the Founder Behind Kirwan Financial Services
Kirwan Financial Services was built to help individuals and business owners approach taxes with clarity, confidence, and intention, not confusion or last-minute stress.
I founded this firm after seeing too many people do everything right throughout the year, only to feel blindsided at tax time. They were earning income, growing businesses, and making smart decisions, yet their tax strategy didn’t reflect that effort.
Today, Kirwan Financial Services serves clients who want more than just a completed return. My work centers on accurate, compliant tax preparation paired with thoughtful, forward-looking strategy so clients understand where they are and how to plan for what’s next.
This is where tax preparation meets education, structure, and long-term thinking.
Stress-Free Experience
I simplify the tax process by handling the details with care and precision, so filing feels organized, supported, and manageable—not overwhelming.
Forward-Thinking Solutions
I prepare every return with a forward-looking mindset, helping clients think beyond the current year and make informed decisions with confidence.
Trusted Expertise
As an IRS tax professional, I bring experience, accuracy, and integrity to every client relationship, because trust matters when it comes to your finances.
Client-Centered Approach
I work directly with my clients and take the time to understand their goals, questions, and concerns. This is a relationship-driven practice, not a one-size-fits-all service.
Meet Cassie Kirwan
I’m Cassie Kirwan, founder of Kirwan Financial Services and an IRS tax professional with an MBA and a strong background in analytical, process-driven work.
Before building my firm, I developed a deep appreciation for structure, accuracy, and thoughtful decision-making—skills that now shape how I approach tax preparation and planning. I bring that same clarity-focused mindset into every client relationship.
As my practice has grown, so has my commitment to helping clients feel informed and empowered—not dependent—when it comes to their taxes. That’s what led to the creation of the WhipSmart CEO Tax Strategy Framework, a proactive approach designed for business owners, self-employed professionals, and high-earning individuals who want to understand their numbers and plan intentionally.
I believe tax strategy should support real life, not complicate it. My goal is to help clients feel prepared, confident, and supported every step of the way.
