While Florida has no state income tax, residents there still pay taxes in other ways. But the overall burden is low relative to most other states.
Property taxes are about 1% of assessed value. But don't let that percentage number seem high. The median value of a home in FL is all of around $150k.
So while other states, say California, has a lower property tax rate, the median home values there are 3 times as large as in FL. Thus, in CA even with a lower rate, their residents pay more in taxes.
Sales tax in Florida is probably the largest of the tax burdens a resident pays.
All in all, NO income tax, low property tax and a moderately high sales tax, PLUS the sun, not a bad place to be.
Keep n mind though, homeowners insurance is always a challenge in FL. So, get a quote BEFORE you buy a house!!!
