How do I pay due tax by deadline?Usually my only income is the state pension and my annual income is lower than the tax threshold and so I do not have to do a tax returnI This year only I have rental income of £7,500 and after allowances and reliefs I calculate that I have £162.54 to pay in tax. I have a Government Gateway number but do not have a UTR number as I have never had to submit a tax return before. If I apply to be registered for Self Assessment a UTR number will not be allocated to me until after the online filing deadline for 2021-22. I obviously want to avoid a late filing penalty. Is there a way that I can pay this small amount of tax without a UTR please.
