Hi I have just paid mine and my husbands self assessment tax bill by online payment through my bank. However, the reference number is hmrc rather than tax reference number for mine, however its correct for my husband. Both payments have come from the same bank account. Do i need to do anything so that hmrc is aware payment has been made an to be allocated against my account? I don't think the phone line is going to be an option given its 30 January!
