"* Under Regulation 73 of theIncome Tax (PAYE) Regulations 2003 , it is the employer's obligation to make End of Year returns by the due date. Our online system shows that no P35 was received on20 April 2010 . On checking with our online support team they have confirmed that the P35 for [ name redacted ] was received on the20 April 2010 at 09:28, the P35 for [ name redacted ] was received at 09:35 on the20 April 2010 (not 09:42) and there is nothing showing an attempt to file for Oz Building Construction Ltd 547/EZ14395 at all, should that be a test or otherwise until the2 November 2010 . HMRC website guidance (please see enclosed excerpt) advices that you will receive an acceptance or rejection message when you submit your return. * Can I please draw your attention to the e-mail provided in that it does show a 'successful receipt of online submission for reference 567/EZ55…' at the head of the copy, but a reference number 547/EZ14395 for all other receipts. Unfortunately I cannot ascertain as to why this discrepancy occurred. Whilst I recognise that the return was then submitted upon receipt of the penalty the fact remains it was not filed until the2 November 2010 . * HMRC is not required to issue reminders. Although penalties are charged on a monthly basis there is no statutory timetable HMRC must follow when issuing the notices. Penalty notices are not reminders."
