|The core charge is a deposit and I don't think I've ever been taxed. Usually the core charge is a separate item on the receipt but if it was rung up as a miscellaneous item or by someone who didn't know better then taxes may (accidently) be added.|
But then I'm not in Texas.
It's probably best if you called some place like Pepboys or the parts department at a dealership and ask if they charge taxes on a core charge and if so, if the taxes are refunded when you bring in the core. They are more likely to give accurate info than some high school dropout at a junkyard.
So I suppose you googled the word 'core' and were led here with a discussion of dual core cpus?
