I registered as self employed recently, starting a few years ago, but have only started making more than £1k this year. I was regularly employed until June 23. I got letters through to do my self assessments to covered since I started my self employment, fine… nothing to report as less than £1k so should be straight forward. I did these last week. Comes up that I owe tax and that my company car hadn’t been accounted for, for the last few years (21/22) despite my P11d being completed correctly and sent to HMRC via employer. I complete all my self assessments and owe a chunk of tax… ouch. Today I get letters advising of fines over £400 for late payment of tax..! Surely this isn’t my fault, HMRC have given no indication of tax due despite having all the information, if I appeal is this a situation they are likely to waiver the tax due and fines?
