Make sure you get and keep your receipts, especially for the big items like engine, trans, rear end. If you have paid sales tax on the big stuff you should not have to pay it again. For the kits you get out of state and don't pay tax on when you buy them you will have to pay the tax when you register but you will still need the receipt and MSO (Manufacturer Statement of Origin). Even if you buy and pay for the items you have to prove the items are not stolen, Keep the receipts.

That is another reason the donor concept is popular, the donor should come with a title.

If the big items are in order they usually assume you bought the small stuff locally and paid sales tax.

The last car (street rod) I built I used an engine out of a truck I owned so I didn't have a receipt for it, but I had the receipt for the wrecking yard engine I put in the truck, so with that and a statement of facts they accepted that I already owned the engine and had already paid tax on it. It can be a nightmare if you don't keep the paper trail intact.
