Where to receive and store package?

I'm having a problem right here. My business mainly deal with importing and exporting. I have to ship a lot of stuffs to and from the US. Most of the things I buy from other places I have to receive them at my house or my workplace. Recently, the house owner and my boss said that I can not ship the packages to those place because the IRS will track it down. There is nothing wrong with the packages and my business. I just don't want any trouble to my house owner and my boss
So what should I do here? Where can I get an address to ship all of my packages? I need a real address to deliver everything to store until I ship them out again

so, what should I do there? Where can I find a place to ship all of my items and store them there?

You could rent office or warehouse space.

If you want to be cheap, get a mailbox with the UPS Store or Postal Annex or some such. You can either bring them home or rent a storage unit. I've heard some storage unit places will accept mail/packages, but I don't have experience with that.
