For over thirty years, our family owned and operated accounting business has continued to aid our clients in all manner of tax-related needs such as income and sales tax preparation, bookkeeping services, and payroll preparation.

We highly value not only continuing education and compliance training within our staff, but also attempt to consistently educate our clients regarding their ongoing tax obligations. Our dedication to honesty, competency, and accuracy underlies all we do at Lillis & Company, but what feeds our passion for the industry rests within the resulting relationships formed with you, our client.
