As a Swiss resident who has inherited US assets, you may be subject to US inheritance tax. US assets can also include stocks listed on US markets (for example Sunrun or Beyond Meat). Nonetheless, the exemption limit is set at USD 60,000. If your stocks (or other assets) from the US therefore are valued at less than USD 60,000, you are neither tax liable nor are you required to declare your assets in the USA.
Since your Inyova portfolio is well diversified across different countries, you generally only have to consider this if you have an investment upwards of CHF 200,000. If this applies to you, please feel free to contact our customer success team for more details on your portfolio: email@example.com.
