Many years back I invested a few thousand dollars in a stock fund. My intention was to "buy and hold" and occasionally add a little here and there. However, life changes meant that I didn't have extra money to contribute. At some point, I must have missed a letter or something, as I recently received a notice from my state that said they had money from the fund in their "Unclaimed Property". I filed the necessary paperwork and received a check for what must have been the value of my holdings in the fund at the time it was declared "unclaimed".
When tax time rolls around, will I be responsible for any taxes (income or otherwise) on this money? (I live in Maryland in the United States.)
