subtax

I live in UK since last 2 years and i have an NRO [NOT NRE] or non resident ordinary account in india. I already pay 30 percent income tax to indian government on any interest earned from fixed deposit held in that acount. 1. as i am in 40 percent tax bracket in UK, do i need to pay additional 40-30 = 10 percent tax in UK as self declaration? 2. Or, I have to pay another 40 percent tax to UK government and show the reciept of 30 percent tax paid to Indian governemnt to get some credit? what proof is required for this - could you please suggest entire process. in any case, do the total interest paid to UK and Indian governement can exced 40 percent?

I have a CASH ISA account from last year and i was saving in it till May 2024. After that, i have opened a new CASH ISA with another provider for better interest rate. Can i still continue saving in both Cash ISA? Or i should close old one and transfer my money to new Cash ISA and use the new one only for future savings? With new rules in 2024, can i open a new stocks and shares ISA this year and operate it alngwith my old/new CASH ISA?

I live in UK and work from here for UK company. I used to send money to India from UK in my NRE account. I have earned around 800 pound interest in NRE account in last UK financial year. Do I need to pay tax in UK for this amount in case i want to bring the money back to UK now or paying tax is required only when interest income is beyond 1000 pound in an year? If i need to pay tax in UK, then could you please share the process how can i pay tax for this in UK? Also, NRE interest is not taxable in india. But while paying UK tax for this interest, can i still apply 15 percent credit as per DTAA agreement?
