My primary residence is in Massachusetts (which has a significant state income tax). I also own an apartment in Florida where I live half of each year (FLA has no state income tax). So, to save on state income taxes, I'd like to change my primary residence to FLA.
I'd still live in my current MA house half of each year for, say, the next 10 years. By changing my primary address, as above, I'd lose the advantage of the primary-residence home sale exclusion when I eventually sell the MA house to downsize to a smaller house there.
I'm looking to have my cake and eat it too; i.e. stop paying state income taxes and still get the primary home sale exclusion on my much-appreciated house in MA. I wish I could sell my MA property now, pay any taxes owed (after the $500K exclusion) and then buy it back immediately (probably a sham transaction). Anyway, that would salvage the $500K primary residence exclusion as well as significantly increasing the cost basis of my house in MA. Then when I sell the MA house in ten years hence I would have to pay tax on the full gain (I believe the MA house will not appreciate significantly above the new cost basis during the next ten years.)
Is there any legal way I could have my cake and eat it too?
