When you notify Hacienda about the 030 form, there is a very high chance you will receive an audit for the previous four years, and questions about any source of income or accounts including any undeclared EMI accounts, crypto etc. This is just a provisional measure. Additionally, you will be added to their list, and after-the-fact they can claim that you have your center of vital or economic interests in that location. Ideally, your house should not be in your name; it’s better to hold it under a company, and even better if someone else is living there and you can demonstrate it.
