Marriage Allowance

Both my wife and I do not have job income, but are relying only on interest income to maintain our daily expense. The interest income which are being generated under our joint named account, are normally more than GBP12,570 every year. So, who, either she or I, both of us should file the tax return? If the interest income will be filed my me, does it mean that my wife is not required to file the same income again in order to avoid being double taxed? If my wife filed no income but only me, can we enjoy the Marriage Allowance? Thanks

Hi Man Kit Derek Lam,

As it is  a joint account that you have, the interest should be splt 50/50 and only if your share exceeds £10,000 then you would need a tax return - both of you if your share is over the 10k.
If not, you can both send details in a letter for any tax due to be calculated.

Thank you.
