What time does the tax year end?

It’s much safer to have everything wrapped up by Wednesday afternoon of 5th Apr

That would be too late for some providers, who have earlier cut off times.

Having ‘everything wrapped up’ does not mean starting anything. It means knowing the cutoff times of your providers well in advance, and having your tax position as you would like it at the end of the tax year, by the afternoon of the last day of the tax year, instead of relying on last-minute Faster Payments in the final hour.

Also remember that IT glitches can occur either at your own funding bank account or the ISA manager so it's best to make the contribution, where possible, with plenty of time to spare and try not to leave it to the last moment. ISA managers have been known to return the whole contribution if the subscription exceeds the limit by even a penny, etc. Try to leave time to resolve unexpected issues.
