New York State Residency Tax Audits: The Out-of-State Practitioner's Field State Tax Resolution Field Guide Series, Volume One

Your client forwarded a letter from the New York Department of Taxation and Finance. They are being audited on their residency status. They believe they moved to Florida two years ago. New York is not so sure.

New York runs one of the most aggressive residency audit programs in the country. If the Department determines your client is still a New York resident, they are taxed on their worldwide income for the entire year, not just the income sourced to New York.

For a high earner who believed they had left, the difference between resident and nonresident treatment can repeat across several tax years and produce substantial tax, interest, and penalties.

Your IRS training does not fully transfer here. Federal residency turns on citizenship and physical presence in the United States.

New York residency turns on domicile, on day counting inside a single state, and on a body of law and Department guidance that most out-of-state practitioners have never read. The burden is also different: the taxpayer has to prove they left. New York does not have to prove they stayed.

This field guide gives you the framework to handle the case the right way.

What's inside:

• The two independent doors into New York residency, and why the defense is different for each
• The 184-day trip-wire and the part-of-a-day rule that catches clients off guard
• The permanent place of abode trap and the Gaied rule (Matter of Gaied, 22 N.Y.3d 592)
• How the Department reconstructs a client's whereabouts using toll records, card swipes, key-card logs, and cell data
• Inside the audit: the questionnaire, the information document request, and what the Department's own published guidelines say
• A full worked case study: a physician's Florida move under audit, from notice to resolution
• Outcomes, appeals, and the strict 90-day protest clock
• A glossary and a full, traceable source and authority appendix

Who this is for: Enrolled agents and CPAs who are comfortable with IRS examinations but have never handled a New York state residency audit, especially one in a state they do not practice in.
