PROFESSIONAL ACCOUNTING Services

KC Gillis CPA is a boutique accounting firm built on a simple idea: business owners deserve technical expertise while retaining the responsiveness of working directly with a CPA. Founded by Kassi Gillis, a licensed CPA, the firm brings technical skills to real estate investors, multi-entity business owners, and clients navigating international tax complexity.

​

Based in Richfield, Wisconsin and serving Washington County and beyond, KC Gillis CPA provides bookkeeping and tax services with a specialty in real estate portfolios, multi-owner property groups, and businesses with cross-border tax needs — areas where most local firms simply don't have the depth.
