Frequently asked questions

Do I have to pay New York City income tax?

If you are a resident of New York City, yes: the city levies its own personal income tax on top of New York State and federal income tax. Non-residents who work in the city generally pay New York State tax on that income but not New York City resident tax. Residency rules can be complicated if you split time between places, which is one reason people moving to New York often hire an accountant.

What is a CPA?

A Certified Public Accountant is licensed by the state after passing the Uniform CPA Exam and meeting education and experience requirements. In New York, licenses are issued by the New York State Education Department, which has a public verification search.

Do I need a big firm for my personal taxes?

Not usually. Firms like these suit business owners, high-net-worth families, people with complex investments or cross-border income, and anyone moving to the US who needs pre-immigration tax planning. For a straightforward personal return, a smaller CPA practice or enrolled agent is often more cost-effective.
