Today I received a tax calculation notice from the Inland Revenue to say that they had operated the wrong tax code during the years 2003/4 and 2004/5. It would appear that during each year I have underpaid by £1100 (total £2200)
The error appears to have happened when I asked for a tax allowance for my first child (born May 2002) and asked for a childs tax credit of £1049 for one year. However, it appears that they gave me an allowance of £10490 (note the extra 0!) and my tax code went from 473L to 950T. I just thought that this was normal and have really not taken much notice of my tax notices over the last few years. I am a teacher employed by my local LEA so assume that all my tax is sorted for me.
I notice my tax code is now 1015T which is way over what it should be (or so I have found out!) I am a basic rate tax payer.
They have informed me that I will have to repay the error starting April 2007 and I assume that this will be over 12 months (which worked out at £183 a month). I will obvioius need to have my present tax code reassessed but I don't mind that.
Surely if the IR have made a mistake then I am not liable. I tried ring them today but their 'systems were down'
Any experts out there know what my rights are?
