I’m looking to sell some shared that I have in a mutual fund that tracks the S&P 500 to diversify my investing account. Ideally I would sell all of it and move it into some etfs. I’m currently down 700$. Would selling it at loss allow me to deduct the entire 700$ from my income or only a percentage. I usually get returns from my income tax since they withhold a lot from me, would it increase the value of my return by 700$? If I buy the etf immediately (VOO & VXUS) will it trigger a wash sale?
