Residency rules, sticky taxes, and first-year steps (2026)
2026.1 Edition · Revised 2026-07-25 · DomusDay Research
The move changes the rate; the record decides whether it sticks. Missouri keeps taxing until domicile actually changes, and its 183-day statutory test stays live while any Missouri abode is maintained. Below: what follows leavers, and the Florida steps that build the record.
At Missouri's top marginal rate (4.7%), every $100,000 of taxable income is $4,700 of state tax — an illustration at the top bracket, not an effective-rate calculation. Official rate tables are linked below.
F.S. §222.17 provides a sworn declaration recorded with the clerk of circuit court — a formal, dated public record of domiciliary intent that few states offer, and a common early step for new residents.

Source ↗Article X §4 exempts a Florida homestead from forced sale by most creditors, with exceptions for taxes and assessments, purchase-money and improvement obligations, and labor performed on the property.
Source ↗Florida is the easy half. Missouri decides whether the move counts, and it decides on evidence — the two tests below stay live until the record closes them out.

The headline delta: Missouri taxes its top bracket at 4.7% while Florida has no personal income tax. At the top marginal rate — an illustration, not an effective-rate calculation — every $100,000 of taxable income is $4,700 of state tax that stops accruing once Missouri residency actually ends. The rules above decide when that is; the day count and the domicile record decide whether it holds up.
The first weeks in Florida matter more than they look: each step below produces a dated document, and dated documents are what answer a Missouri examiner years later. Do them early and the record starts on your side of the timeline.
New residents obtain a Florida driver license within 30 days of establishing residency; F.S. §322.031 applies the 30-day rule to nonresidents who take employment or enroll children in school.
Source ↗Vehicles are titled and registered in Florida within 10 days of establishing residency or taking employment (F.S. §320.38).
Source ↗Voter registration is available online, by mail, or in person through the Division of Elections; the registration books close 29 days before an election.
Source ↗A sworn Declaration of Domicile may be recorded with the clerk of the circuit court under F.S. §222.17 — a dated public record of domiciliary intent.
Source ↗The homestead exemption requires permanent residence as of January 1 and an application filed with the county property appraiser by March 1; a missed deadline waives the exemption for that year.
Source ↗Registration requires Florida coverage — minimum $10,000 personal injury protection and $10,000 property damage liability — written through a Florida-licensed agent.
Source ↗Vessels and mobile homes are titled and registered on the same 10-day timeline as vehicles.
Source ↗Florida has no personal income tax return to file; the Department of Revenue's new-resident guide (GT-800025) describes the taxes that do apply.
Source ↗Use tax can apply to out-of-state purchases brought into Florida, as described in the new-resident guide.

Every rule on this page traces to a statute, regulation, or agency publication, listed in full on each state's own plate.
Thirty, in the aggregate, and only if the other two conditions hold. Section 143.101 treats a Missouri domiciliary as a resident unless no permanent place of abode is kept in Missouri, a permanent place of abode is kept elsewhere, and no more than 30 days of the taxable year are spent in the state. The 183-day figure is the separate arrival-side test for someone who is not domiciled here.
A permanent place of abode maintained in Missouri fails the first element of the departure exception, and the exception is conjunctive — so resident status stays in place on the department's reading of §143.101 whatever the day count. What the record shows about the home, and when, carries the analysis.
It does not, for individuals, from tax year 2025 forward: 100% of capital gains reported for federal income tax purposes is subtracted from federal adjusted gross income on Form MO-A. The subtraction covers short-term and long-term gains. The residency date decides which realizations fall inside it.
For city-performed work, yes. The tax defined by §92.111 covers compensation earned by nonresidents of the city for work done or services performed in the city, so the split between city and non-city workdays is what matters after the move. Ending city residency ends the tax on earnings from elsewhere.
Form MO-1040 with Form MO-NRI, which states the residency dates and computes the Missouri income percentage. A part-year resident is treated as a nonresident but may compute tax as if a resident for the whole year, and may use Form MO-CR instead — one individual cannot claim both.
