Clarity over Cash ISA

I deposited 20k in a cash ISA last year and made approx. 1k interest.
I noticed that when I login to my account it states I have another 20k "remaining" to invest.

I assume this is because of the new tax year.

If I deposited it another 20k this tax year will the interest on the 41k be tax free?

    Each tax year runs from  6th April to 5th April, you get £20k ISA allowance each tax year, though rumours are that could be reduced, look here
    All interest in an ISA is tax free. have a read here.

    Thanks, I'm aware of the rumours about reductions with the push to get more people to switch to stocks & shares.

    So, just to clarify I can add an additional 20k each tax year, as it stands and any previous 20k investments plus accrued interest are tax free. 
  • Correct.
    Remember if you decide to switch to a new provider, say to get a better interest rate, you must get new provider to do the switch, you can't just take the money out and transfer or you will lose ISA status.
