New York Estate Tax Cliff and Florida: What Moving Saves

The estate tax cliff is the one New York buyers discover and immediately call their estate attorney. The income tax savings pay for the move. The estate tax savings pay for the next generation.

How the New York Estate Tax Cliff Works

New York’s estate tax operates differently from the federal estate tax: (1) Below the exemption: estates at or below $7.35M (currently): zero New York estate tax. (2) Between 100% and 105% of the exemption ($7.35M to $7.72M): only the amount above $7.35M is taxed. A $7.5M estate pays tax on $150K at rates starting at 3.06%. (3) Above 105% of the exemption (above $7.72M): the ENTIRE estate is taxed from the first dollar. No exemption applies. (4) The cliff in numbers: Example: $8M estate. This exceeds the $7.72M cliff. New York taxes the full $8M. Tax calculation: approximately $773,200. An estate of $7.349M (just under the $7.35M exemption): zero NY estate tax. $651,000 difference in estate, $773,200 difference in tax. (5) The effective marginal rate at the cliff: moving from $7.71M to $7.73M in estate value crosses the cliff and triggers tax on the full $7.73M. The marginal tax rate at the cliff can exceed 100% — adding $1 in estate value costs more than $1 in estate tax.

What Happens Without Portability

New York does not allow surviving spouses to use a deceased spouse’s unused exemption. This is the most significant structural difference from the federal estate tax: (1) Federal portability: under federal law, a surviving spouse can “inherit” the deceased spouse’s unused federal exemption ($13.99M in the current year). A couple can effectively shelter $27.98M from federal estate tax through proper planning. (2) New York non-portability: New York does not allow portability. The first spouse’s $7.35M exemption is lost if not fully used at death. A couple where the first spouse dies with $2M in assets and the second spouse inherits those $2M plus has their own $8M: the surviving spouse’s estate is $10M, fully above the cliff. The first spouse’s exemption was wasted. (3) The Florida domicile solution: Florida has no state estate tax. There is no portability issue, no cliff, no non-portability trap. The full $27.98M federal exemption (or whatever the federal exemption is) applies without any New York overlay.

The Gift Clawback Trap

New York has a gift clawback rule that many NY-to-FL movers don’t know about: (1) The rule: gifts made within three years of death (excluding annual exclusion gifts and charitable gifts) are pulled back into the New York taxable estate for estate tax purposes. (2) The implication: a New York resident who makes $1M in gifts in January and dies in December of the same year: the $1M in gifts is added back to the taxable estate. This can push an estate that would otherwise be under the cliff, over it. (3) The Florida domicile answer: a person who establishes genuine Florida domicile and dies as a Florida resident: New York’s gift clawback rule does not apply to the Florida estate. The gifts are simply gifts, not clawback income. (4) Timing critical: the domicile must be established and the person must die as a Florida resident for the full clawback avoidance. Someone who moved to Florida but maintained meaningful NY connections may face a domicile challenge from the NY Department of Taxation.

The Real Estate Transaction as Estate Planning Tool

For New York residents with estates in the $5M–$20M range, the Florida property purchase is as much an estate planning decision as a real estate decision: (1) The FL primary residence anchors domicile: purchasing the Florida primary residence and establishing it as the genuine domicile is the foundational estate planning step. (2) The FL Declaration of Domicile: filing a Declaration of Domicile with the Florida county clerk creates a public, dated record of Florida domicile. This is evidence in any subsequent NY domicile challenge. (3) Timing for maximum estate protection: establishing Florida domicile well in advance of any anticipated estate event and maintaining it consistently (183+ days in Florida, minimal NY connections) produces the strongest protection. (4) The estate attorney’s role: the real estate specialist introduces the Florida property. The estate attorney coordinates the domicile change, the NY estate plan revision (will, trusts, powers of attorney updated to FL), and the documentation of the transition.
