Every year, tens of thousands of high-income families relocate to Florida to eliminate their state income tax burden. Most of them think the move itself is sufficient. It is not. States like New York, California, Connecticut, New Jersey, and Illinois aggressively audit former residents — and they win when the paper trail is incomplete. Establishing defensible Florida domicile is not about where you sleep. It is about what you can prove.
This checklist is organized in four phases, from the practical steps before your move through the ongoing maintenance that keeps your domicile audit-proof. It is not legal advice — work with a qualified attorney and CPA for your specific situation — but it is the framework we walk through with every client making this transition.
Phase 1: Before the Move
- ☐ Obtain a Florida driver’s license within 30 days of establishing residency
- ☐ Register to vote in Florida
- ☐ File a Declaration of Domicile with your Florida county (within 30 days)
- ☐ Update your address with the IRS, Social Security Administration, and all financial institutions
- ☐ Notify your prior state’s tax authority of your change of domicile
Phase 2: Establishing the Paper Trail
- ☐ File for Florida Homestead Exemption (by March 1 of the following year)
- ☐ Move primary banking relationships to Florida institutions
- ☐ Update estate documents (will, trusts, POA) with a Florida attorney
- ☐ Transfer vehicle registrations to Florida
- ☐ Update professional licenses, memberships, and affiliations
Phase 3: Maintaining Defensibility
- ☐ Track days spent in Florida vs. prior state (183+ days in FL)
- ☐ Keep a calendar or log of physical presence
- ☐ File Florida as your tax home on all returns
- ☐ Maintain Florida address on all government documents
- ☐ Review annually with your CPA and financial advisor
Phase 4: Asset Protection (Often Overlooked)
- ☐ File Homestead Exemption for unlimited creditor protection
- ☐ Review tenancy-by-entirety titling for joint accounts
- ☐ Consider Florida-specific trust structures (DAPT, land trusts)
- ☐ Review beneficiary designations on all accounts
Common mistakes that trigger audits
Even families who follow every step above can stumble on the details. These are the errors we see most often — and the ones that former-state auditors look for first:
- Keeping your prior-state driver’s license “just in case.” A valid driver’s license in your old state is one of the strongest pieces of evidence an auditor can use to argue you never truly left. Surrender it.
- Maintaining voter registration in two states. Some families forget to cancel their prior registration. Auditors check.
- Filing a part-year return incorrectly. The year you move is the most scrutinized year. Work with a CPA who understands the statutory residency rules of your departure state — not just the 183-day rule.
- Leaving estate documents governed by your old state. If your will says “I, a resident of Connecticut” and you claim Florida domicile, you have created a contradiction. Update everything.
- Not tracking days rigorously. “I think I was in Florida most of the year” is not a defense. Auditors will subpoena credit card statements, E-ZPass records, cell phone tower data, and social media check-ins. Keep a contemporaneous log.
- Ignoring the “closer connection” test. Some states (notably New York) apply a subjective “closer connection” test that looks beyond day counts. Where are your doctors, your country club, your children’s schools, your place of worship? If those are all in your old state, a day count alone may not save you.
- Failing to claim Homestead Exemption. The Homestead Exemption is not just a property tax benefit — it is also one of the strongest pieces of domicile evidence and provides unlimited creditor protection under the Florida Constitution. File it.
The families who get audited are not the ones who moved to Florida. They are the ones who moved to Florida but left half their life behind.
Florida residency, done correctly, is one of the most valuable financial planning decisions a high-income family can make. The state has no personal income tax, no estate tax, and some of the strongest asset protection laws in the country. But the benefit only accrues to those who do the work — completely, deliberately, and with documentation that can withstand scrutiny.
If you are planning a move, or if you have already moved and are not confident your domicile is defensible, schedule a Florida Residency Review. We will walk through this checklist together and identify any gaps before an auditor does.
