Thanks for the response and additional information
As you are NOT a UK citizen then you have a choice if the income is in excess of £2000 a year
You advsie 220 euros a month which is 2640 a year - you will need to convert this to sterling
So if less than £2000 a year you do not need to declare them as there is no tax arising due to the low level BUT if more then you choose between
1) If you choose NOT to bring or spend this source of income in the UK - then you can ask for this to be excluded, by being taxed under the remittance basis in the UK. If you choose this, then it does see a loss of entitlement to UK personal allowances (the equivalent of £11,000 x 20% = £2200 and this is at the basic rate) AND after you have lived in the UK for 7 of the previous 9 years then you are charges the remittance basis charge which is £30,000 charge a year (and then 12 out of the previous 15- a charge of £50,000)
2) You can claim to be taxed as any UK citizen which is known as the arising basis
This sees you declare ALL income worldwide, keep the personal tax allowances of £11,000 free income a year and then taxed at the appropriate rate bands thereafter (so next £32,000 at 20% then 40% from £43001 to £99,999 which sees a loss of personal allowances - then income in excess of £150,000 a year at 45%)
Let me know if I can assist further, or if you have all that you need, then it would be appreciated, if you could rate me for the level of service I have provided.
