As a virtual CPA practice, Monaco CPA serves Newark clients throughout Essex County, from individual W-2 filers to small business owners managing payroll, bookkeeping, and annual tax returns.
Whether you are a Newark entrepreneur filing your first business return, a freelancer managing self-employment taxes, or a professional navigating NJ/NY commuter tax rules, Monaco CPA provides the focused knowledge and CPA credentials your situation requires.
Newark's economy includes a growing tech and startup community, logistics and transportation businesses, healthcare providers, and a large population of self-employed professionals and gig workers who face complex self-employment tax obligations. Monaco CPA works with construction companies, manufacturers, and restaurants throughout the Newark area.
Many Newark residents work in New York City and face dual-state filing: a New York nonresident return for NY-source wages plus a NJ resident return, with a NJ credit for qualifying tax paid to New York. New York City's personal income tax generally applies to NYC residents, not NJ commuters - but proper filing is essential to avoid double taxation.
Newark's Opportunity Zone designations still matter for real estate investors and startup founders with realized capital gains - but the rules have shifted. Under the legacy Qualified Opportunity Zone rules, previously deferred gain is generally recognized no later than December 31, 2026, and a new 2026 investment cannot earn the former five- or seven-year basis step-ups, so evaluate current law before investing.
Newark's logistics, construction, and restaurant employers depend on flexible labor, and that's exactly the hiring pattern NJ's worker-classification rules scrutinize most. I build the classification review into payroll services so the question is answered before the state asks it.

"Filing my taxes is usually no big deal, but 2025 was a major hassle due to the new crypto filing regulations, and specifically because exchanges like Coinbase weren't reporting cost basis. My own CPA wasn't crypto-knowledgeable and couldn't help me pull reports from Coinbase and Genesis. I spent hours researching crypto-knowledgeable CPAs and spoke with half a dozen firms - quotes ranged from $2K to $6K to reconcile my crypto sales and file my return, plus $400 to $600 an hour for anything extra. Then I found Monaco CPA. I left Greg a voicemail and he returned my call the same day, answered all my questions, and quoted me way less than anyone else. He got everything done - crypto reporting and taxes filed - within two weeks. Super satisfied, and I'll be using Monaco CPA for my 2026 return. Highly recommended!"

"I've known Greg for many years, and he's always been incredibly reliable and detail-oriented. He's a hard worker who runs a tight ship and operates with honesty and integrity. Greg has always been great with his own finances, and I would trust him without hesitation to handle mine or anyone else's. I'll definitely be recommending Monaco CPA to friends and family. If you're looking for a CPA who is upfront, disciplined, and genuinely cares about doing things the right way, Greg is your guy."
