Common Questions

Business Tax Questions — Answered

The questions NYC and NJ business owners ask us most before getting started.

A business tax return reports the income, expenses, and tax liability of your business entity — LLC, S-Corp, C-Corp, or partnership. A personal return (Form 1040) reports your individual income, which may include income passed through from your business. Most small business owners need both. We prepare both in a single engagement so nothing is missed and the numbers flow correctly between them.

Common signs include: paying more than 25–30% of net profit in combined taxes, not having an S-Corp election reviewed, missing depreciation or Section 179 deductions, not maximizing retirement contributions, or not separating personal and business expenses. We review every new client's prior returns for missed opportunities — most find at least one significant item.

Yes. Every engagement includes federal, NYS, and NYC returns (where applicable). For NJ businesses, we include the NJ Corporation Business Tax or Gross Income Tax return. Multi-state businesses operating in both NY and NJ get both state returns prepared together with proper income allocation — no extra coordination required.

Standard turnaround is 7–10 business days once we have all your documents. During peak season (February–April) it may be 2–3 weeks. If you have a hard deadline — a bank loan, investor due diligence, or an IRS notice — let us know and we'll prioritize accordingly. Rush preparation is available for an additional fee.

For most small businesses we need: last year's return (if applicable), a profit & loss statement or bank statements for the tax year, any 1099s issued or received, records of major asset purchases, payroll records if you have employees, and your EIN. We'll send you a detailed checklist after your free consultation — and we'll tell you exactly what's missing so you're not guessing.

Yes — multi-year unfiled returns are a core part of our practice. We prepare all outstanding years, calculate your actual liability (often less than you fear), identify penalty abatement options, and communicate with the IRS and NYS on your behalf. The sooner you start, the less interest and penalties accrue.
