Yeah, absolutely right. Sorry -- I confuse even myself, frequently...
Domicile for
tax purposes is IL. Airlines use the word "domicile" meaning "based in" but to avoid confusion, if you write them back, I recommend you use the word "based" in any reference to Fresno to avoid confusion. Only use "domicile" to refer to your tax domicile, which is IL.
In addition to aforementioned licenses, leases, property taxes, FED income tax forms with your IL address on them, if you can show major purchases (credit card reciepts) for stuff like large appliances it helps. It'd be pretty unlikely that you'd buy a refridgerator in IL if you live in CA (and vice versa). NOT saying go out and buy a fridge just to avoid CA taxes, but if you make any major purchases, keep the receipts!
