Tax office / employer mistake is costing me £1800!!!

Chocolate25

Hi,
I pay tax via PAYE as an employed member of staff in the NHS.
I also pay tax via self assessment for any jobs I get on the weekend (in ther performing arts). When I started my new NHS job, the student loans company were not informed, and therefore the correct amount of student loan contribution was not taken.
After writing numerous letters and making hours worth of phone calls back and forth, it came to light that the amount I owe is at 1800 and continually rising.
Also, when my tax returns were sent in, and the tax office entered my details incorrectly, so the return for 09-10 was confused with the return for 10-11.
In the beginning, I was told I owed 500 pounds, and when I queried why, I was then told that I owe 1800.
I do not understand the ins and the outs of how or why - even after receiving invoices... nothing seems to make sense.
I feel that a mistake was made (either by my employer or by the tax office), and now I am being mato pay for this error.
Is there anything I can do about this? Can I ask that some of the amount is waived? Or that some of the interest is waived? Or that my employer takes the hit for not informing the tax office of me being emploeyed?
Is there anyone that can help me or tell me what the various options are?
I've tried speaking to staff at the tax office but to honest, the matter is so complicated, I do not think even they understand.
PLEASE HELP!

well

IF you post your first and second job earnings and tax code (for both years) and pension contributions made that would be a start.

There is a difference between student loan deductions and tax and student loan deductions should be shown separately - so who is asking for the £1800? The student loans company or HMRC?

CLAPTON

are you actually being asked to pay that amount or is that simply the amountstill outstanding?

but really we need the figures for each year to make any sense of the matter.

When you started your NHS job did you have a P45 to give them or did you comple a P46? In either case was the relevant box (box 5 on P45, box D on P46) marked to say you had a student loan? If it was then it's the emplyer's responsibility to inform HMRC and you may have some sort of case against them, if not then it's down to you - assuming of course that you did have a student loan and there was an amount outstanding when you started the job.

By the sounds of it your £1,800 would go to pay your student loan, so you'd have less debt. It's not actually "costing" you anything.

At 9% above £15k ........ that's potentially a lot of income (£20k) from the weekend 'performing arts' work?

But - PAYE + SA does admittedly cause some strange anomalies with SLC deductions.

Many thanks for all your comments. I will post accurate figures when I get home.
In response to Mikeyorks - the weekend work was nowhere near that - i'm estimating 5k extra a year tops.
