I am starting a new computer service company, and I'm having a hard time figuring out whether or not I should be charging tax. After reading the following link: http://taxes.state.mn.us/taxes/sales...AT_1100107.pdf I am under the impression that if I'm doing something like a virus/spyware cleanup or fixing an error with Internet Explorer that it's not taxable. But if I'm installing a new computer system or software that it is taxable. I'm just not really sure though.

Any help would be greatly appreciated!
