Online retailer Amazon.com made headlines last year when it began collecting every state-level sales tax on its direct sales. Savvy observers quickly noted that this change did not affect the company’s large and growing “marketplace” business, where it conducts sales in partnership with third-parties and rarely collects tax. But far fewer have noticed that even on its direct sales, Amazon is still not collecting some local-level taxes.

Corporate America is doing alright. Corporate profits soared last year, and 2018 has already brought a major windfall in the form of the Trump-GOP tax law, which dramatically cut the federal corporate tax rate from 35 percent to 21 percent and shifted to a territorial tax system, giving income earned offshore by U.S. companies a free pass by no longer making it subject to U.S. taxes.

When Republican leaders rushed through an overhaul to the federal tax code over a seven-week legislative period, they failed to acknowledge that many provisions in their bill would have negative consequences for states. One such provision of the Tax Cuts and Jobs Act that undermines state laws is the expansion of federal tax breaks that now allows taxpayers to use 529 savings plans to pay for private K-12 education.
