Lowell General Hospital and Saints Medical Center serve a population that’s grown 10% since 2010, driven by the city’s affordability compared to Boston suburbs. The Acre and Centralville neighborhoods house a vibrant Cambodian, Brazilian, and Latin American business community, with over 200 immigrant-owned enterprises along Middlesex Street and Broadway.

Massachusetts’ new millionaire’s surtax adds 4% on income over $1M, making the effective rate 9%. The PTEE election allows pass-through entities to pay at the entity level, creating a federal deduction. Business owners near the $1M threshold should carefully time income recognition and consider entity-level strategies.

Lowell is home to 4,900+ small businesses and a population of 115,554. From Advanced Manufacturing, Healthcare, Technology to professional services, Lowell business owners need CPAs who understand Lowell’s diverse immigrant-owned business community faces language barriers and complex international tax situations including FBAR and FATCA compliance and can provide year-round tax planning — not just compliance.
