Minnesotans are savvy shoppers. It's no secret to most of them that online shopping often offers bargains -- especially when one shops on websites that do not collect the sales tax that the law requires.
That's right: If you live in Minnesota, when you click the "buy" button to purchase a taxable item, sales tax is owed, whether or not the seller collects it. Minnesotans are bidden by law to pay any uncollected sales tax when they file their income tax returns.
But with no enforcement mechanism to compel compliance, that requirement may be the most widely disregarded feature in the state tax code.
This situation isn't unique to Minnesota. It's the consequence of federal court decisions made 20 years ago that limited states' sales tax reach to online sellers with a physical presence within their borders.
The online purchases that escaped taxation as a result amounted to a small, slow leak in state revenues 20 years ago. That leak is now a major breach in the revenue pipelines of all of the 45 states that rely on sales taxes.
According to the National Conference of State Legislatures, Minnesota is losing $455 million in fiscal 2012 in owed-but-uncollected tax on online purchases.
The NCSL tally for all 50 states is $23.3 billion -- enough to have averted some of the worst of the budget cuts states have inflicted on schools, public safety and human services since the Great Recession began.
One of the best things Congress could do to assist fiscally struggling states is to help them collect taxes they are already owed. Several measures have been introduced that would require all online sellers to collect state sales tax at the time of purchase, regardless of whether the seller has a physical presence in the state where the sale originates.
