theodp writes to tell us that according to the Wall Street Journal, Amazon.com has raised a few eyebrows with their strategy to avoid paying sales tax in eight states where they have warehouses or distribution centers. "As an online retailer, Amazon can avoid collecting sales tax in states where it has no presence, at least until Congress changes the law. But in states where a company has actual facilities, such as warehouses, states tax officials can require the company to collect sales tax. Despite operating hundreds of thousands of square feet of distribution facilities in the eight states, Amazon says it doesn't have any presence in them. The company argues that it doesn't operate the plants, its wholly owned subsidiaries do."
