Online self assesment

Hello,

Can anyone tell me - Is the calculation at the end of the online tax return set in stone, or does it get double checked and then confirmed by HMRC ?

Many thanks

The calculation is, as near as one can say, flawless. Have you identified some kind of error? The contents of the return which gave rise to the calculation is open to checks by HMRC, either randomly, because of a more technical aspect (e.g. complicated Capital gains) or because something 'jumps out' (e.g. 500% increase in motor expenses for a sole trader).

If you're asking if HMRC will send confirmation that the calculation is correct then I think the answer is no. You do your return and pay the tax due, you're responsible for making sure you do it by the due dates, don't wait for HMRC to say how much you owe because they reckon they've already told you when you submitted the tax return!

Is it correct? Well, it depends on your figures, if they are correct, then it should be correct. I have seen a lot of tax calculations and still have not seen any incorrect one, mathematically speaking. But I am not saying that it is always never wrong, as I don't know that.

It is called SELF ASSESSMENT for a good reason, if you include all taxable income, tax deductions, etc correctly, the calculation should be correct. But HMRC may check it later. The enquiry window is 12 months, I think.
