<prompt> Human: I live in Connecticut and I got a letter from the State of Connecticut Department of Revenue Services. It says that Newegg has provided records of my online purchases during taxable years 2014, 2015, and 2016 that I was not charged state sales tax on. It says the total purchases made during this time frame are around 2000 so I owe about 125 in taxes, 13 in interest, and 13 in penalties. It also says that if I sign the enclosed Use Tax Acceptance Form acknowledging that I made purchasesowe the taxes I can pay this amount minus the penalties.The actual details included in this letter are pretty vague other than the totals. It only says that I made purchases during at least one of the listed years. Theres no actual dates or transaction details included. Ill have find all my records and try to check the accuracy of these claims. I did buy a lot of expensive parts to build a computer at one point, but I believe that was in summer-fall in 2013, not the listed years.What is the legality of this? Am I really responsible for paying this if the retailer refused to collect sales tax? Can I disputerefuse to pay this? Can I at least request an itemized list to see what they believe I owe money on?EDIT:Thanks for your input everyone. It seems like its realtheres no way out of this. Other than verifying numbers, theres not much to do other than pay it. I guess Im just not purchasing from Newegg again if it turns into tax hassles like this.Assistant: Check the numbers are right, but yea you owe it, best to just pay.I do think its insane they are sending you a bill for sales tax from years ago. But you owe it and youre not going to be able to prove otherwise.Human: Ill request more specific details from them on Tuesday if possible but mostly Im pretty annoyed that Im getting a random tax bill for around 150 dollars from purchases made years ago.  <response>: Its not random, you didnt include those purchases when you filed in those years.
