@lthurman15 you brought back some painful memories haha. So, I calculated my cost basis by going through my statements for each transaction. I took the value of the shares when they vested (and the taxes were automatically withdrawn) and used that as my cost basis. Then, I took the value I sold those specific shares at to determine my gains that I actually owed taxes on, since initial taxes were taken out at vesting, I should only owe the difference in what I made from vesting until the sale. What complicated this was that it was all in Swiss Francs, so I had to do the conversions for each transaction, using the exchange rate on that given date. Since I only held the shares a few months after they vested, it wasn’t a significant gain and the tax burden wasn’t much. On the vest date they took out standard payroll taxes, so that was where the biggest hit was. Also, the 1099 they issued was mostly empty and completely inaccurate, so I dismissed that altogether. Hopefully your company’s broker isn’t as difficult to parse.
