What NYC & NJ Business Owners Say

5.0 · 47 Google Reviews
"As a new LLC owner in Queens I was overwhelmed by business taxes. OnPoint walked me through everything — bookkeeping setup, quarterly estimates, and my first business tax return. Now I feel totally in control of my finances."

Sofia M.

Founder, SM Consulting LLC — Queens, NY

"OnPoint is the best small business accountant on Long Island. They cleaned up two years of messy books, caught deductions my previous accountant missed, and got me a refund I didn't even know I was owed. Exceptional service."

Denise W.

Owner, Denise's Hair Studio — Long Island, NY

"I needed a New Jersey accountant who truly understood small business taxes and S-Corp elections. OnPoint nailed both. The S-Corp election they recommended saved me over $8,000 in self-employment tax last year alone."

Founder, Bright Start Tutoring — Montclair, NJ
