Please note that the following answer only applies to clients of our german Wealth offering.‌ 
Tax optimisation may affect your broker portfolio. Dividends, coupons and sales in the broker may result in taxable events after the wealth tax optimisation in mid-December. 

However, before the tax optimisation - between the end of November and mid-December - you still have the option to opt out of the tax optimisation by phone or email at service@scalable.capital.
