Taxation of US Military compensation payments when declared during the visa process

I am a US citizen and veteran. My wife is an EU national and moved to the US with me on a fiance visa. We now plan to move back the UK permanently. I will be applying via spouse visa. In the US I receive approx. $4,300 per month via military disability compensation (not retirement or pension). We plan to use those payments as proof of income for the spouse visa process. The payments are not taxed in the US. As far as I understand I do not need to pay taxes on that income while I am living in the UK. I am looking for confirmation on this matter. My other concern is that by declaring the US military compensation payments during the spouse visa process, it might be subjected to different tax laws, and therefore could be taxed later down the road. Please advise, thank you in advance!

Hi Logan,
This income sounds similar to a UK war pension/armed forces disability pension and is not taxable in the UK.
We cannot comment on future events as legislation and/or plans may change.
Thank you. 

Would declaring it in the visa process change anything as far as taxation? Would the income need to be self reported if deposited in a UK bank account? Would it be taxed in that case? Thanks again.

Hi,

The income is not taxable in the UK and doesn't need reporting.

You would need to check with the Home Office regarding the visa information required.

Thank you.
