I have a magazine with an office in the state of Florida. We are planning to sell ad space to clients from all over the US. I'm trying to find out if by operating in Florida I have to include Florida sales tax to the ad space we sell to clients in the magazine or not? As I understand it, advertising sales usually aren't subject to sales tax since it's not tangible goods. But I'm sure this varies from state to state. So would sales taxes based on the location of our company, or based on the location of the client buying the ad space?
Another words, if we sell ad space to a company in California, do we need to know the California tax regulations or do we simply abide by the Florida ones? And to take it a step further, does it matter where our company is incorporated? If our company is incorporated in NJ, but we have our office in FL, which tax laws do we abide by (if applicable)?
