We do collect sales tax and remit to the state of Massachusetts. If you are tax exempt, please select this option during checkout. Accounting will follow-up before order ships to collect a copy of your sales tax exemption to have on file with your order. If you’re an out of state buyer, shipping to an out of state address, we do not collect sales tax for a majority of the states. It is the buyer’s responsibility to notify their state and submit the tax on their own behalf.
