I’m not quite sure what your trying to get exemption for so I can’t answer your specific question.

The address situation is ultimately for the CA Board of Equalization to decide.  I would think that if you just added a Suite A and Suite B to the addresses for the companies you would allow the BOE to be able to distinguish between the addresses for the two companies.  There are many places where businesses are in the same building and use this method to provide different addresses.

Just as a generally rule, one business entity can not be liable for another business entities tax liability.  Unless there is some cross mutual business dealings that links both companies.  For more specifics on this you would need to consult an attorney.  Since I’m not one I am prohibited from giving this type of advice.

The common rule for sales tax is that if you are purchasing the product to resale you don’t have to pay the Vendor sales tax as long as you provide them with a certificate of exemption.  The Vendor should be able to provide you the form… you complete it (be sure to put you CA sale tax license number on it), return it to the Vendor, they verify the number, they make a reasonable(good faith) determination that this would be a type of product that your company would resell, if they determine it is most likely for resale then they begin selling you their product without sales tax.

You would then be responsible to collect any sales tax due when the product is sold and remit it to the state in the manner they have provided.

If you are drop shipping into other states and the Vendor has nexxus within that state they may have to charge you sales tax since the Vendor is liable to collect the sales tax for that state if you don’t have a license to collect sales tax for the state.

I hope this helps.  If you can provide me with more details of you specific situation I will try to help further.

Thanks,
