Returns we prepare
- Schedule C for sole proprietors and single-member LLCs
- Form 1065 partnership returns, with a Schedule K-1 for each partner
- Form 1120-S for S-Corporations
- Form 1120 for C-Corporations

Key deadlines for calendar-year businesses
- March 15 — partnerships (Form 1065) and S-Corporations (Form 1120-S)
- April 15 — C-Corporations (Form 1120) and sole proprietors, on the personal return
- Extensions are available, but an extension gives you more time to file — not more time to pay
What to have ready
We'll confirm your exact list when we talk. Most clients need:
- Last year's business tax return
- A profit and loss statement — or your bank and card statements for the year
- Payroll reports and W-2 / W-3 summaries
- 1099s you received, and 1099s you issued to contractors
- Records of equipment or vehicle purchases
- Business mileage log
- Business loan statements
Please don't email your Social Security number or tax forms. After we talk, we'll tell you exactly how to send your documents.
Common questions
My records aren't organized. Can you still help?
Yes. We can clean up your books first so the return is accurate — see Bookkeeping & Payroll.
Does my LLC file its own tax return?
A single-member LLC usually reports on your personal return (Schedule C) unless it elected to be taxed as a corporation. A multi-member LLC files a partnership return (Form 1065) by default.
Can you file returns I missed in past years?
Yes. We prepare late business returns and help you get current with the IRS and New York State.
