Do I have to use my resale certificate? Can I stop using and and paying taxes on just keys when I buy to avoid?
We can't really answer sales tax questions since every state is different. In the states where I have lived, a merchant would not pay sales tax on materials, provided that they charge sales tax on the final product or service. For income tax purposes, you deduct whatever you pay for the item as your cost ($1 for a no-tax blank, or $1.10 for a taxed blank, for example).
