Inheritance tax reference numbers

longwalks1

hi everyone
we are currently filling in IHT400 and IHT436 (claim to transfer any unused residence nil rate band). I’m unsure if we need to get a Inheritance Tax Reference Number for mum (who passed away last month) and for dad (who passed 9 years ago).

our calculations, reading gov.uk and reading on here there will be no IHT to pay, so do we still need to get a tax reference number for mum (and dad?) ? 

I read it as you’d only need a tax reference number for mum/mum and dad if you have IHT to pay? 

Thank you all again for your help

If your father’s estate owed IHT it should have been sorted 9 years ago. If everything went to your mother that would not have been the case. As long as her estate will owe no IHT you don’t need a reference.
