This looks as though I may need to complete one of these for the state of FL as well? As far as filling out the W4 which needs to be turned in tomorrow (5/13) for my start date on Monday (5/16).. I am still unsure how to proceed.
Let's go back, there's some needless confusion been added.
It doesn't matter what address you put on the W-4. Use whatever address you want your employer to send your paycheck or other important mail.
Generally, in most states with income tax, the state will have a separate withholding form (in New York, it's called IT-2104), but if you only fill out a W-4, your employer can generally extrapolate what your state withholding should be. Since Florida has no personal income tax to withhold, there is no separate withholding form for your state income tax and you only need to file a W-4. Since Florida has no personal income tax, there is no 6 month minimum (although there may be minimum residency requirement for other tax breaks, such as vehicle taxes or property taxes, but you will have to ask in Florida. Try your county's tax assessor office.)
Regarding state income tax responsibility. You are considered a Michigan resident and owe MI state income tax on all your world-wide income until you do two things:
1. abandon your MI residency (or domicile)
2. establish a new permanent residency (domicile) some place else.
The location of your domicile is determined by analyzing many factors and is not determined by the date on any one particular document. Your domicile is your permanent home, it is where you have allegiance. Some factors include the location of your permanent home, your friends, church, significant social and business relationships, , doctor, dentist, voter registration, and so on. It is possible to be away from your home for a long time without actually changing your domicile.
For example, if you move to Florida but you are unsure if or when you might move back to MI, and you maintain connections to MI (property, professional relationships, relatives you visit often) then MI might still consider you an MI resident.
Changing domiciles requires that you actively abandon your old domicile and set up a new one. But there is no minimum time frame required.
For example, if you sell your MI home and move to Florida with the intent of making it your new permanent domicile, and you take other steps like changing your doctor and dentist and so on; but it doesn't work out and you decide to move back after 6 months; it may still be the case that you changed your domicile to Florida and then changed it back.
The date you change domiciles is the date it actually happened, regardless of when you get the paperwork fixed.
For example, you moved into a Florida home on May 5, with a lease that was effective May 1. Your old lease in Michigan expired May 31. You update your car registration and drivers license in July, your voter registration in August, and you see your new Florida dentist in November. The date you changed domiciles was May 5, even though specific bits of paperwork that prove you changed domiciles were dated before or after the actual move.
If you changed domiciles, you will owe MI income tax for the period of time you lived in MI, and you would file a "part-year resident return" at the end of 2022.
