About us

Osa Services Inc., (Osa) started as a sole-proprietorship in 1993, initially providing tax services to individuals in the Dorchester, and Roxbury neighborhoods of Boston, Massachusetts. The business grew quickly, which led to its expansion. As a result of its expansion, Osa had to relocate its business from the popular Mattapan Square area of Boston, to another popular and busy area part of Boston in January 1997, the Ashmont Station neighborhood, where it’s currently located. Osa was incorporated in 2003. Shortly after incorporation, it applied and was granted the S-Corporation Status by the Internal Revenue Service. Over the years, Osa has diversified into Accounting, bookkeeping, payroll, and business consulting services. Our core continues to be taxation: Individual, business, and non-profit.
