Live in Connecticut? Bought anything from Newegg in the past four years?
Congratulations! You can look forward to a nastygram from the Department of Revenue Services, along with a bill for Sales & Use Tax for all of your Newegg purchases going back to 2014.
Plus interest and penalties, of course.
That's not a worst-case scenario. They may very well use this information as a starting point…after all, if you bought from Newegg, you probably made other online purchases, too…so the sky's the limit. They might decide to audit you and demand you bring your credit card statements.
