“HMRC letter dated 15 th July stated the law says there must be reasonable excuse for failure to pay the tax owed by the due date and the reasonable excuse must have continued throughout the whole period when the payment was overdue. I believe there was genuine reasonable excuse for late payment and that HMRC contributed considerably to the cause of the delay. The circumstances and facts are as follows:- On 26 th January I moved home. I was 76 at the time and for 10 months extensive refurbishment of the property had been undertaken. My new home is an old listed Georgian building and delays in planning and extra costs had arisen. The extent of these extra costs was not known until January, 2015. I was in a situation where I had to pay the builder substantial extra costs and also had a considerable tax bill to pay. Both required payment to avoid penalty by the end of February. I immediately applied for and received a mortgage. The mortgage provider required Forms SA302. My agent requested these on 29 th January. The mortgage was available subject to receipt of forms SA302. HMRC letter dated 16 th September 2015 – first page, last paragraph states – “there is no note of a phone call made by your agent on 29 th January 2015 requesting a copy of your SA302 for your mortgage application.”
