A Morris County CPA firm that knows your name

Large firms can make you feel like a file number. As a boutique practice, we keep every engagement close: you work directly with a CPA who knows your return, your business and your goals. We're based in Mine Hill, in the western part of the county, and work with clients throughout Morris County, including Morristown, Parsippany-Troy Hills, Randolph, Dover, Rockaway, Denville, Madison, Chatham, Florham Park, Hanover Township (Whippany and Cedar Knolls), Boonton, Montville, Roxbury and Mendham.

Most of our work happens through a secure client portal, by phone and by video call, so you never have to take time off to drop off documents. We respond within one business day and are available Saturdays as well as weekdays.

Tax preparation for Morris County individuals and families

Whether your return is straightforward or complicated, it's prepared and reviewed by a CPA, not run through software and sent back. We regularly handle:

Morris County small business tax planning

Morris County is home to thousands of owner-run businesses: professional practices, contractors, consultants, medical offices and family companies. For them, a tax accountant should do more than file the return. We help you:

New Jersey doesn't follow federal bonus depreciation, and it imposes its own minimum tax on S corporations, so your state return often differs from your federal one. We plan for both.

New Jersey and New York multi-state compliance

Many Morris County residents commute to New York, whether on the Morristown Line from Dover, Denville, Morristown, Madison or Chatham, or work remotely for New York employers. That usually means a New York nonresident return alongside your New Jersey resident return, with a credit for the tax paid to New York. New York's "convenience of the employer" rule can also tax days you work from home in New Jersey. We prepare both returns together, so the credit is claimed correctly and you aren't taxed twice on the same income. See our guide to New Jersey and New York multi-state taxes.

New Jersey tax controversy and IRS representation

A letter from the IRS or the New Jersey Division of Taxation is stressful, but it's rarely as bad as it first looks. As CPAs, we can represent you directly, so in most cases you never have to call the agency yourself. We handle:
