I received a bill from Keene Gas charging me $36 for minimum use, because we only use about 50 gals per year. I'm ok with that but when I saw that they taxed on this FEE I decided to question it. I checked with VT Dept of Taxes at http://www.state.vt.us/tax/contact.shtml and was told that as long as the propane is used for residential purposes it is not taxable and neither is the minimum fee. Keene Gas has been charging VT sales tax on their deliveries to VT for at least 2 years now. Check your invoices. I'm curious to see how wide spread this is. ...
