I got fed up with paying the accountant good money for doing very little, I just completed my online self assessment.
They want all the money I owe by Jan 31st, nothing new there, but now they want half as much again on account for 2110/11. This is also payable by 31st Jan. They want another payment for the same amount on account 31 July.
Reading this they want the equivalent you paid in tax for 09/10 by 31st July 2111.
I had already paid some on account last July, so I deducted that amount from the payment. It's supposed to be easy, but to be fair I found it quite confusing.
The old bank account is gettig hammered early this year.
