Then I want one too. This is the highest dividend payment I receive each year. And every year it's a few euros more. Of course, I always get the withholding tax back (annually, but you can also submit an application for the last 3 years), so it's worth it for this amount. The refund is done online, I have been using the account with the Swiss authorities for years without any problems. It is important that you have the tax voucher from the bank. Enter your details in the portal, upload the tax voucher, print out the application and have it stamped by your local tax office. Then send the whole thing to Switzerland and about 3 weeks later you have the money in your account. Everything is totally easy and takes about 15 minutes plus 2 trips to the post office.
