S-Corp Tax Preparation for NYC & NJ
Expert S-Corp tax returns, reasonable compensation analysis, and S-Corp election strategy. Flat-fee pricing. 100% in-house.
OnPoint Business Tax & Accounting prepares S-Corp tax returns (Form 1120-S) for small and mid-size businesses in New York and New Jersey. Our enrolled agents handle the federal return, NYS IT-204-LL, NYC filings, and the shareholder K-1s — all in a single flat-fee engagement.
We also help LLC owners evaluate whether an S-Corp election makes sense for their situation, run the numbers on reasonable compensation, and handle the Form 2553 election filing when the time is right.

A complete service — not just a transaction.
Form 1120-S Preparation
Complete federal S-Corp return including all schedules, shareholder K-1s, and built-in deduction review.
Reasonable Compensation Analysis
We determine a defensible reasonable salary for shareholder-employees — the most audited area of S-Corp returns.
S-Corp Election Strategy
