“i. The whole problem started in January 2010 when I started work for CSC Computer Sciences Ltd. The crux of the problem is that despite numerous opportunities to do so, CSC Payroll set my tax coding at BL. Rate. When you start work for CSC, the way they calculate your actual "take home pay" is very complex. You have an amount of money (your Flex Fund in CSC language), and out of that you can choose how you receive the money. There are mandatory pension contributions to be deducted , but you can optionally take use some of the Flex Fund to purchase benefits, such as Life Insurance, additional pension contributions, company car etc.. What the CSC system doesn't actually show you, is the impact of these changes on your "take home pay". In short, after you have made your selections, you don't actually know what your "take home pay" will be until you receive your wage slip. ii. I made my selections prior to receiving my first pay from CSC, so when it did arrive, I assumed that (the net amount) was normal. I was never aware, and no indication was given that tax was being taken at an incorrect rate despite CSC knowing my full earning potential and relevant tax position (such as earning too much to be entitled to a personal allowance). iii. Firstly I believe that CSC failed in its duty towards me as an employee and its actions (or lack of) were the root cause of the current problem. The ability to resolve this problem was with CSC and not me. iv. To make matters worse, the situation continued to the end of 2009-10 and through 2010-11, until March 2011. It was only because I (not CSC) completed an online self-assessment that the issuance of a new tax code was triggered that brought the problem to light. v. When my "take home pay" did change in April 2011, I made the assumption that the newly reduced "take home pay" was as a result of me completing the self-assessment, and HMRC were now recovering monies due in 2009-10, prior to my employment with CSC. vi. During the period of October 2011 to November 2011, I was in contact with HMRC by phone to try and understand why, considering I was working on PAYE, and had been since January 2010, HMRC was claiming I still owed tax. It came as a nasty shock to find out on the phone, that HMRC hadn't been recovering money owed, but actually my current "take home pay" was now correct in terms of coding and tax payable. An even greater shock was being informed that I had therefore amassed a liability for tax in years 2009-10, and 2010-11. In a (telephone) discussion with HMRC during that period, I questioned the legality of CSC's position, and stated that I would be writing to HMRC to complain and appeal against this accrued liability. HMRC were very helpful and understanding on the phone, but at no point, made any reference that penalties and interest would be accruing whilst the matter was being investigated. vii. It took until the17th January 2012 for me to receive a response to my letter of the15th November 2011 . It was a very supportive letter in terms of looking into whether CSC had made a mistake. The letter does state that "if we do agree that your employer was at fault they will be directed to make payment in full". What the letter does not mention, at any point was that that penalties and interest would be accruing whilst the matter was being investigated. viii. I duly responded and provided a highly detailed analysis of why I considered CSC to be at fault, and that HMRC should intervene to recover the outstanding tax. ix. On the17th May 2012 , I received a letter from HMRC stating that "for tax year 2010-11, an underpayment arose as you were not due a personal allowance as your income exceeded£100,000.00 ". However, HMRC made a decision that, although I had offered significant evidence, and the CSC had a duty and opportunity to ensure my taxation was correct, the fault was mine (for not taking action that I didn't know I needed to take). Again, what the letter does not mention, at any point was that that penalties and interest would be accruing whilst the matter was being investigated. x. On the19th June 2012 , I responded to the letter from HMRC stating that I disagreed with the findings, would like to launch an appeal, as if I cannot get resolution with HMRC, I would be considering legal action against CSC for breach of duty of care. xi. On the7th August 2012 , I received a letter from HMRC stating that "HMRC cannot hold CSC Computer Sciences accountable for the tax underpaid". Again, what the letter does not mention, at any point was that that penalties and interest would be accruing whilst the matter was being investigated. Following HMRC's unwillingness to take action, I contacted CSC Computer Sciences Ltd and advised them that I considered they had breached their duty of care, and was considering legal action. I was in discussions with CSC HR and Payroll through August 2012. I got a response from CSC Payroll in mid-September 2012, in which they stated "that I had slipped through the net on headcount" and they hadn't requested a P45, although in their opinion, they were not liable. xii. In late October 2012, I contacted a solicitor who specialised in employment and taxation issues to invoke my last resort action of taking legal action against CSC for the recovery of unpaid tax through a breach of duty of care. The advice I received in early November was that although I was not treated fairly, in the eyes of the law, I would be unlikely to win any legal pursuit. xiii. Having, in my opinion exhausted all due process that I knew about, I resolved myself to having to pay the accrued liability, despite it being accrued through no fault of my own, and caused by events outside of my control. xiv. In my letter of the25th March 2013 , I did request that the debt be reduced to principle sum (tax owed) without interest and charges. Subsequent to that letter, I had a long conversation with HMRC on the24th April 2013 . The gentlemen who dealt with my query fully understood the case, could see why I felt penalised for something that was essentially not my fault, and was very helpful in getting the matter resolved. I asked him for a settlement figure that would exclude charges and interest. He informed me that£20,981.91 was owed and that I should pay that as soon as possible. I paid£500 that week, and the balance was paid by the13th July 2013 . He also said I should write to HMRC with details of "reasonable excuse" in order to get the previous charges revoked and state that during the "due process" there had been no mention, at any point, that penalties and interest would be accruing whilst the matter was being investigated. xv. On the2nd May 2013 , despite the assurance and phone call of the 24th April, and despite making payments, I was informed that the deadline for appeal had passed. I therefore wrote, to HMRC with a letter of "reasonable excuse" on the5th August 2013 . Throughout this process, I have not been ignoring HRMC, but communicating fully. Due to the nature of written communications, there have delays on both sides between receiving a letter and responding to it. All I have done is exercise due and legal process in full view of HMRC. Payments were not made earlier as the matter was in dispute. I believe I have acted in good faith in a situation that was not of my making, and not fully under my control. I therefore believe there is a strong case for HMRC to remove all penalties and interest accrued for tax years 2009-10 and 2010-11. After all, the tax liability caused by CSC has been paid by me, and the penalties relate purely to the due process that was followed in conjunction with, and in the full knowledge of HMRC.”
