Hi mark3066,
In your case, you have a choice.
If you pay the tax through your tax code, then the tax payable on your property income, is collected throughout the year and the final liability is, hopefully, below £1000, so POAs are not required.
Your alternative, is to removed the deduction from your tax code and pay the tax in POA 2 instalments by 31 January and 31 July each year. You would need to contact our Self Assesment helpline on 0300 200 3310 or contact our webchat facility here to make any changes:

Thank you.
