On PF, used position transfer to move position from IB.
Low amounts of dividend, can reinvest directly using the 18 CHF per quarter trading credit.
Higher amounts are wired back to IB (wire fees are like 15 USD iirc) for reinvestment.
Need to file R-US in addition of DA-1 (and some opportunity cost due to that, but that’s pretty small, I typically get the refund in summer of the following year).
