Florida 183-Day Rule: Why Florida Counts No Days
Quinn Moran · September 25, 2026
There is no 183-day rule in Florida: it has no personal income tax, so it has no residency test and does not count your days. The counting is done by the state you left, usually in two ways: a statutory-resident test that applies if you keep a home there and spend more than 183 days there, and a comparison of your days in that state against your days in Florida, which feeds into whether your domicile really changed.

Florida is the one move where the destination state never asks how many days you spent there. It has no personal income tax, so it has no residency test to run and nothing to count. The counting still happens, but the state you left does it, and it usually keeps two separate tallies with different rules.
This post covers those two tallies: what each one measures, how a day is scored, and where Florida's own filings sit on the same calendar. For Florida domicile as a whole, including the homestead exemption, the Declaration of Domicile and the evidence auditors weigh, the Florida tax residency guide sets out the rules in one place.
Is there a 183-day rule in Florida?
Florida's constitution prohibits a personal income tax. Florida has no state income tax return, no statutory-resident test and no day threshold. It also imposes no estate tax and no inheritance tax.
Florida residency does have legal machinery, but it concerns domicile, meaning your permanent home, and it works through documents rather than arithmetic:
- The Declaration of Domicile under Fla. Stat. §222.17 is a sworn statement, filed with the clerk of the circuit court in your county, that your Florida home is your permanent home. The statute expressly covers people who keep homes in other states, who declare their Florida home to be their predominant and principal home.
- The homestead exemption, claimed on Form DR-501, requires you to swear that the home is your permanent residence.
Neither filing creates domicile by itself, and neither involves a day count. The former state decides whether a person really left, using its own rules.
Tally one: your old state's 183-day rule
Many states treat a person as a statutory resident when two conditions are both met: they keep a home in the state, and they spend more than 183 days there in the year. Most northeastern and midwestern states have a test like this, and a statutory resident is taxed as a full resident.
Two features of this tally surprise people who have moved to Florida.
First, it ignores domicile. Someone can hold a Florida driver's licence, a filed Declaration of Domicile and a homestead exemption and still be a statutory resident of the old state if they kept the northern house and went past 183 days there. The Florida paperwork plays no part in the calculation.
Second, a day does not have to be a full day. In most of these states, any part of a day spent in the state counts as a day there. A morning in the old state followed by an afternoon flight to Florida counts as an old-state day. So does a day that starts in Florida and ends with a late arrival up north. In those states, travel days in both directions go into the old state's column.
This is why the rule of thumb many people rely on, "six months and a day", says little about where they actually stand. Months of nights in Florida can sit alongside an old-state count that is higher than expected once every travel day, weekend visit and short trip back counts as a whole day.
Tally two: old-state days against Florida days
The 183-day line is a bright line. The second tally has no line at all.
Even when a person stays under every statutory threshold, auditors compare time spent in the old state with time spent in Florida. States weigh where a person actually spent the year when they decide whether that person's domicile really changed, whether or not they also have a statutory-resident test. A year with more old-state days than Florida days is hard to square with a claim that Florida is the principal home.
The comparison is made for each year separately, so one well-documented move year does not settle it. Florida days might lead in the first year and then slip in the second or third, and audits of those later years are designed to find that pattern.
| Tally one: statutory residency | Tally two: the comparison | |
|---|---|---|
| Question | Was a home kept there, and were more than 183 days spent there? | Where was the year actually spent? |
| Threshold | More than 183 days | None; the days are weighed against each other |
| What counts as a day | In most of these states, any part of a day | Old-state days against Florida days |
| Role of Florida filings | None | Weighed separately, as evidence of domicile |
| Outcome if it goes against you | Taxed as a full resident | Domicile treated as never having changed, so all income is taxable there |
Where the Florida filings sit on the calendar
Florida's filings carry dates, and those dates become fixed points on the calendar the old state is rebuilding.
The homestead exemption shows this most clearly. To qualify, you must have owned the home and made it your permanent residence as of January 1, and you must apply to your county property appraiser by March 1 using Form DR-501. The exemption takes up to $50,000 off the assessed value of the primary residence. It also brings the Save Our Homes cap, which limits annual growth in the home's assessed value to 3% or the change in CPI, whichever is lower.
The homestead application is a sworn statement that the home was your permanent residence on January 1. The Declaration of Domicile is a sworn, dated, public statement that Florida is your predominant and principal home. The old state can obtain both as evidence in its audit. If the day record for the months around those dates shows most days spent in the old state, the audit file contains sworn statements and a calendar that tell different stories.
Florida enforces its own rules on the property side. County property appraisers police the homestead exemption. Claiming homestead on a home that is not truly the permanent residence, or keeping a residency-based exemption in another state at the same time, leads to repayment of the tax break with penalties and interest, plus a lien.
How the old state rebuilds your year in an audit
Auditors do not depend on the taxpayer's memory. New York, California and similar states run dedicated nonresident-audit programmes aimed at recent Florida movers. They subpoena cell records, card statements, EZ-Pass records and flight histories, then rebuild the year from them. The data trail is covered in detail in how states use smart meter and cell phone data. For how two of the most active states approach this, see leaving New York and leaving California.
Two features of these audits matter for day counting:
- The burden of proof usually sits with the person who moved. The old domicile lasts until it is abandoned and a new one is established, and the mover has to prove the change.
- The lookback covers several years. The move year plus one or two more can be examined if the income makes it worthwhile, and the audit window generally covers the move year plus the two or three years after it.
A reconstruction from third-party records answers the question "where was this person on this day?" years later, from data the taxpayer did not choose. A contemporaneous log answers the same question, but it was recorded on the day itself.
What a day count settles, and what it does not
The day record settles tally one directly. Once the days are known and the state's rule for part-days is applied, the 183-day test is simple arithmetic; the free 183-day calculator runs it, and the state lookup shows which rule your old state uses. The day record is also the main input to tally two.
It does not settle domicile. Domicile is a question of fact about where a person actually lives and intends to stay. It depends on the home, the household, the homestead and declaration filings, licences and registrations, and the calendar, all taken together. That decision is not a day count.
The day record also has no effect on source income. After the move, the old state can still tax rent from property there and income from a business operating there. In some states that also includes equity compensation earned while working there. Days come back in with wages: wages for days physically worked in the old state stay taxable there. That makes the day record relevant to income sourcing as well as residency.
Where iReside fits
iReside records which country and state you were in on each calendar day, from your iPhone's location, in the background. Day counts for each rule you track are computed from that record continuously. The old-state number builds up as you go, so nobody has to reconstruct it in December, or three years later in answer to an audit letter.
The day-by-day record exports as CSV or PDF, and each day is labelled with its source: GPS, manual entry, or a planned future day. That labelling matters here. A record that separates GPS days from manual entries is a different kind of document from a calendar filled in from memory, and a planned future day is marked as a plan, not as history.
The Florida side of the file (the Declaration of Domicile, the homestead dates and what Florida does and does not require) is set out in the Florida residency guide. The Florida residency proof checklist lists the documents that back it up.
