HMRC Admin 10 Response

Hi
Any interest arising on savings within your ISA are tax free.  If you take that interest out of the ISA and use on general day to day expenses, then any interest arising from the money taken out of the ISA will be taxable.
 

Hi
No. You need to send the whole return either on paper or buy 3rd party software to file online.

Hi
You don't need to declare any kind of ISA interest on your Self Assessment return - as such, it doesn't count towards the £10,000 interest threshold for needing a return. You can read more here - Individual Savings Accounts (ISAs)

Hi
You will need to telephone 0300 200 3300.

Hi
No the trading allowance is £1000 for the full tax year no matter when started.

Hi
1. for joint accounts it is 50/50  2. the form 17 is for income in joint names and not just property. You would still need this to change the split on the joint interest account. Your wife will be entitled to the £17570 you refer to for income in her name only.

Hi
Please refer to Self Assessment tax returns

Hi
Yes you need to show separate income and expenses.

Hi
It sounds like you have completed the wrong box as the income tax losses should be empty. The losses need to be shown in relation to the type of income they refer to - self employment or capital gains.
