The 7 Factors Tax Authorities Use to Determine Domicile

Domicile is not defined by which address you put on your tax return. Courts and state tax departments use a multi-factor test to determine where a person's 'true home' — their fixed, permanent place of abode to which they intend to return — is located. New York's audit criteria (the '183-Day Rule' plus 'Permanent Place of Abode' test) is the most elaborate in the nation.

| ContentWhat Auditors Look ForContentHow to Satisfy It** | | --- | --- | --- | | 1. Time Spent (183-Day Rule) | Most states use a 183-day rule: spending more than 183 days per year in a state creates a strong presumption of domicile. New York uses this rule aggressively — combined with the 'permanent place of abode' (PPA) test. If you maintain a NY apartment AND spend more than 183 days in NY, you are a NY statutory resident regardless of claimed domicile. | Keep a contemporaneous daily log of location — credit card receipts, cell phone records, E-ZPass, airline tickets. Spend 183+ days in the new state. Spend fewer than 183 days in the old state. Do NOT maintain a New York apartment as your primary abode. | | 2. Primary Home / Permanent Place of Abode | NY: maintains a 'permanent place of abode' in NY? If yes + 183+ days in NY = NY statutory resident for income and estate tax purposes. 'Permanent place of abode' includes apartments, condos, houses — even if they are not your 'primary' home. | Do NOT keep a NY / CA / MA apartment after claiming new domicile OR reduce to a truly temporary, transient arrangement. Size down dramatically. Better: sell the old-state home entirely. A Florida condo alone is not enough if you're still maintaining a 3BR Manhattan apartment. | | 3. Driver's License and Voter Registration | Obtain new state driver's license and voter registration; surrender old state license and registration; re-register vehicles in new state. | Do this within the first 30–60 days of move. File change of address with USPS and update all important accounts. | | 4. Professional and Business Relationships | Transfer primary attorney, accountant, financial advisor, and physician to new state. Open new state primary bank account. | Change primary professional relationships to new state within first year. Keep records of the transfer. | | 5. Declaration of Domicile | Execute a formal Declaration of Domicile in the new state (Florida: F.S. §222.17; other states have similar procedures). File with the new state court or county. | Execute Declaration of Domicile within 30 days of establishing new residence. Florida procedure: file with Clerk of Circuit Court of the county where you reside. | | 6. Estate Planning Documents | Update will, trust, and healthcare documents to reflect new state domicile. Documents that still reference old state domicile are evidence of continued connection. | Re-execute will and trust in new state with explicit new-state domicile statement. Update all documents within 90 days of move. | | 7. Social and Community Ties | Religious affiliation, club memberships, charitable activities, social activities — all weighed as evidence of the 'center of life.' A New Yorker who maintains their NYC club membership, attends synagogue only in New York, and visits grandchildren in New York 200 days a year has not really left New York. | Join a religious institution, club, or community organization in the new state. Establish social ties. These are harder to quantify but matter in an audit. |

The New York Domicile Audit — The Most Dangerous in the Nation

New York Audits Domicile Changes By the Wealthy More Than Any Other State — And Wins:

New York State Department of Taxation and Finance has a dedicated unit that audits claimed domicile changes by high-income and high-wealth individuals. The audit process can begin at death (estate tax audit) or during the taxpayer's lifetime (income tax audit of a claimed non-resident). NY uses a 'domicile questionnaire' that asks detailed questions about where you spend time, keep your valuables ('near and dear' test — where do you keep your jewelry, art, family photos, pets?), maintain business relationships, and conduct your daily life. NY court cases have found domicile to remain in New York even when taxpayers purchased Florida homes and claimed FL domicile, because they maintained a Manhattan apartment and spent significant time in NY. Key: if you maintain ANY significant presence in New York — a large apartment, regular extended stays, or primary business relationships — a claimed FL domicile will be difficult to defend.

| ContentWhat NY Examines Specifically** | | --- | --- | | Time | Daily calendar; credit card records; E-ZPass records; cell phone tower records; airline records | | Near and dear items | Where do you keep your jewelry, art, antiques, family photos, china, silver, pets? | | Business connections | Where is your primary business conducted? Where are your board meetings, client meetings, business address? | | Family and social contacts | Where do your children, grandchildren, and closest social circle live? Where do you attend religious services? | | Permanence of FL home vs. NY home | Is the FL home furnished like a primary residence? Size comparison matters — a 400 sq ft pied-à-terre in Miami with a 3,000 sq ft Manhattan apartment does not suggest FL domicile | | Active business in NY | Active management of NY businesses weighs heavily toward NY domicile regardless of time spent elsewhere |

Post-Move Estate Tax Risk: The 3-Year Look-Back

If you change domicile and die within 3 years of the move, the old state may challenge whether domicile was truly established. While there is no statutory '3-year rule' for domicile in most states, the practical reality is that recent domicile changes are more likely to be audited and challenged. Tax authorities look at the totality of circumstances at the time of death — not just what the taxpayer said before death. An estate attorney should be engaged immediately after any domicile change to document the change thoroughly.

| ContentOld-State Audit RiskContentDocumentation Priority** | | --- | --- | --- | | Year 1 (within 12 months) | Very high — domicile change is brand new; old-state ties likely still strong | CRITICAL — daily location log, Declaration of Domicile, professional transfers, all 7 domicile factors must be aggressively documented | | Year 2–3 | High — old-state scrutiny continues; new ties still being established | Continue all documentation; add receipts, club memberships, medical appointments in new state | | Year 3–5 | Moderate — new domicile becoming established; old ties fading | Maintain documentation; ensure all professional relationships have transferred | | Year 5+ | Low to moderate — well-established domicile; old ties minimal | Standard estate administration; domicile less likely to be challenged if properly established |
