New York Tax Topics We See Most Often

Across our NY-resident and NY-source-income clients, a handful of topics drive most of the year-end planning conversations. Understanding which of these apply to your situation is usually a faster path to a productive consultation than starting from a blank slate.

• NYC Statutory Residency — the 183-Day Rule: A taxpayer who maintains a permanent place of abode in New York City and is physically present for 184 or more days in a calendar year is taxed as a NYC resident on worldwide income. This applies regardless of where the actual domicile is located. The 183-day count is unforgiving — partial days count as full days, and the burden of proof is on the taxpayer. We handle the documentation and substantive analysis required to defend non-residency, including the "permanent place of abode" analysis that turned in cases like Gaied.
• Convenience-of-the-Employer Rule: New York's convenience-of-the-employer rule treats wages earned by a non-resident remote worker as NY-source if the work is performed remotely "for the employee's convenience" rather than the employer's necessity. This rule is responsible for an enormous amount of NJ-NY commuter overpayment and the corresponding refund opportunity for taxpayers who can document a true necessity-based remote-work arrangement.
• NYC Unincorporated Business Tax (UBT): Single-member LLCs and partnerships operating in NYC pay UBT (4% on net business income) in addition to NY State and federal tax. Sole-proprietor freelancers and gig workers operating from a Manhattan, Brooklyn, or Queens address are often unaware of UBT until they receive a notice. Entity-structure decisions (S-Corp election, LLC vs. corporation) interact directly with UBT exposure.
• NY Pass-Through Entity Tax (PTET) Election: New York's PTET election lets pass-through entities pay state tax at the entity level — deductible federally — while providing a state credit to owners. The election is annual and the deadline is March 15. The math must be run before electing, because for owners with significant out-of-state income, the election can backfire. We do the modeling each year for clients to confirm the election is still favorable.
• NY Estate Tax Cliff: New York imposes its own estate tax. Its basic exclusion amount runs on New York's own schedule, separate from the federal exclusion and far below it. For deaths in 2026 the New York basic exclusion amount is $7,350,000. It was $7,160,000 for deaths in 2025. Critically, once the New York taxable estate exceeds 105% of that amount, the exclusion is lost entirely. Tax is then due on the whole taxable estate — not just the excess. Estate-planning conversations for NY-domiciled clients should include the cliff analysis and, where appropriate, structuring to keep the estate below the threshold.
