CSA keeps getting the amount wrong

Apart from getting nearly every detail wrong, bar my children’s names and dates of birth, they can’t calculate my weekly earnings correctly.

I get a half-teachers pension, which is a little more than my tax allowance, so it uses up my allowance (obviously) and so my current self employment is then all taxed at 20% – again obviously.

But no – the CSA cannot see that my pension uses up my tax allowance (and is only taxed a teensy ammount). So they are calculating the tax on my self-employment after taking another allowance off the top: a double whammy – making that a teensy ammount of tax too and ending up with over £20 per week too much on my weekly earnings.

Will they listen to reason? No. They are Vogon Bullies.

All this because I lost my SA302 – official tax calculation – despite my sending them the printout of my tax total for the year in question from my internet portal. I had no idea I would ever need my SA302 – don’t I get statements of accounts through the year anyway? I sent them one of these – but they couldn’t interpret it!

Now HMRC are not so busy I might get through on the phone and I should be able to get another (SA302) official calculation in time for my appeal.
