Monaco CPA is a virtual CPA practice serving Denville, New Jersey, and the surrounding Morris County area with personal tax preparation, small business accounting, and bookkeeping services. Known as the Hub of Morris County, Denville is home to commuters, lake community residents, and a growing small business community along Route 10 and Route 46, all of whom benefit from proactive, NJ-specific tax planning.
Founded by Greg Monaco, CPA, the practice is built on personalized attention. You get an experienced CPA who knows your situation and treats your return with care.
The fully virtual practice model means Denville residents get expert CPA support without driving to an office. All consultations are conducted via video call or phone, and documents are exchanged securely through an encrypted client portal.
Denville's 17,100 residents include a substantial commuter population that uses the township's dual NJ Transit lines (Morristown Line and Montclair-Boonton Line) to reach Manhattan and Hoboken. Those commuting to New York face dual-state filing obligations, credit-for-taxes-paid calculations on Schedule NJ-COJ, and potential complications from New York's convenience-of-the-employer rule for hybrid workers. Monaco CPA handles these multi-state returns and helps Denville commuters claim every credit they are entitled to.
Denville's four private lake communities, including Indian Lake with its 1,200 homes, give the township a character unlike any of its neighbors. Lakefront property owners face higher assessed values, and those who rent their homes on a short-term basis must report rental income on both federal and NJ returns while accounting for Denville's 3% municipal occupancy tax. Monaco CPA helps lake homeowners with Schedule E reporting, proper expense documentation, and compliance with local rental requirements.
The Route 10 and Route 46 commercial corridors, combined with a vibrant downtown Business Improvement District, support roughly 673 businesses with a 10.8% self-employment rate that exceeds most neighboring towns. Small business owners in Denville benefit from the NJ BAIT election to bypass the federal SALT cap, S-Corp election analysis for growing consulting practices, and ongoing bookkeeping and payroll support. Monaco CPA also works with medical practices near Saint Clare's Health and service businesses along both highway corridors.
Denville sits at the geographic center of Morris County with direct connections via I-80, Route 10, Route 46, and Route 53. Monaco CPA leverages this connectivity to serve clients not just in Denville but across the broader Morris County area, including Parsippany, Rockaway, Boonton, Mountain Lakes, Dover, and Randolph.
