I just submitted my tax return a few days ago.

I saved the summary form, which shows how much I owed, as a pdf.

I paid what it said was owed.

Two days later I logged in and the box about how much I owed was now empty. So the payment had gone through.

Then just out of interest, I clicked on the View your payments section ( a new feature I think).

And digging around in there, I read I was now over £1000 in credit!

Back to the completed return, it still said the tax due was what I had paid!

So I will be on the phone to them tomorrow (Mondays they often seem to be very busy).

I think they need an update!
