Common Questions

Montclair Business Accountant — FAQs

Common questions from Montclair business owners before working with us.

Most of our Montclair clients work with us entirely remotely — secure document sharing and video calls for consultations. If you prefer to meet in person, we can arrange it — many of our Essex County clients start with a video call and never need to come in. Either way works perfectly.

Yes — home-based businesses are one of our specialties. We help you claim the home office deduction correctly, separate business and personal expenses, handle quarterly estimated taxes, and choose the right entity. Many home-based Montclair clients save thousands each year with an S-Corp election once their income justifies it.

New Jersey businesses face federal income tax, NJ Corporation Business Tax (CBT) for corporate entities, NJ gross income tax on pass-through income, and NJ sales tax if you sell taxable goods or services. We prepare and file all of these as part of our standard service — plus payroll filings if you have employees.

Absolutely. Catching up on unfiled returns is one of our most common engagements. We prepare all outstanding years, calculate your actual liability (often less than you fear), identify penalty abatement options, and communicate with the IRS and NJ Division of Taxation on your behalf. The sooner you start, the less interest and penalties accrue.

Our fees are flat and quoted upfront before any work begins. A typical small business tax return starts around $750–$1,500 depending on entity type and complexity. Monthly bookkeeping packages start at $350/month. We'll give you an exact quote after a free 20-minute consultation — no obligation.
