Back in 2005 we lived in NC, my husband was a contractor for my uncles HVAC bizz. We bought a van, under the incorporation, so that saved us sales tax on the van. Well in 2006 we moved to WV, hubby's incorp. was dissolved and we switched the van over to WV, and paid WV sales tax on it. We recently traded the van in on a car I could use, the deal has been signed, its been almost 2 months. The dealer has paid the van off, and has the title on the van. Now the dealer says that the DMV wont swtich the title over from a NC title to a WV title because we now have to go back and pay the taxes on the van. Is this allowed and should we have to pay that, although the deal has been signed?
