Self Assessment and post Payment on Account

[ConfusedWeb]

Really simple questions ( i think) , but i could not already find an answers in the search

I had a company last year, most payments were dividends so had to pay on account ( in the year 19/20) for 20/21) (fair enough)
This years self assessment (20/21). i owe tax including for some dividends for this year, (way less than last year) but i expected the payment on account from (19/20 for 20/21) figure to cover this, but it does not seem to have been considered in the online calculation. Have i missed something ?

ALso is it simple enough to get the payment on account removed if the majority of you earling are payee, just a web form ?

Many Thanks

When you calculate your tax the actual bill is calculated without refernce yo any payments on acounnt that have been made.

Once return is processed then If relevant payments on account may be revised downover automatically by hmrc systems if relevant - roughly speaking payments on accout will be no more than 50% of final bill each.

SO if 5/4/21 return has ben processed your current position should be updated reasonably quikcly presuming return has been processed.

You can also reduce payments on account as appropriate at any stage - but figures always run the chance of being amended backup later if for any random reason you reduce payments too much.

Note if you are removed from sa the whole problem goes away for the tax year you are moved out of sa.
