I believe that Maine just added it to their form within the past few years, as internet sales proliferated. We have the option of keeping track; or paying a percentage of our income. I usually go with the latter, but when I bought my winch I had to declare it.Its a total serious question. So, guess I need to investigate this. I've not saw a place on my state tax forms to declare sales tax that I owe.
A quote by Clint Eastwood going to confession in "Grand Torino";
"I sold an outboard motor in 1972. I made $50 and didn't declare it on my taxes."
