A Rich History

C. F. Suppa, CPA, P.C., founded in 1983, is a trusted CPA firm located in Massapequa Long Island.  We have a rich history of providing both personal and business tax preparation services to clients throughout Long Island.  By design, it has been a boutique practice dedicated to providing personal service to select individuals and local business owners.  The core of our clientele represents small to midsized businesses that retain our services for accounting, Quickbooks training and support, sales tax, bookkeeping, payroll, and business tax preparation.

Our clients are diverse.  Many clients are simply individuals in need of personal income tax return preparation. Others require services related to small business tax return preparation. Finally, there are multi-state businesses with millions of dollars in annual revenue requiring more complex tax planning.

Last but not least, since 1990 we have provided outsourced per diem CFO and comptroller services for Long Island Business owners making it extremely cost effective for their business by eliminating the various expenses associated with employing a full time CFO or comptroller. The savings are due to the elimination of costly employee health insuranceretirement benefitspayroll taxesdisabilityunemployment, and workers’ compensation.
