HMRC Non Landlord Resident returns

Hi guys

So I have a property in the UK and I registered with HMRC but I have to file my tax return , I was late filing in 2015/2016.

They sent me out a form but I lost it and looking to download a new one online.

I just don't know what form I have to fill out I always thought it was a NRL 1 form but it seems to be the form to register the property on HMRC

Can someone please advise me?

I have found a small bit of more information

Its either a SA100 form I need to file or a SA105 form I need to file..

Does anyone know I think it may be SA105 form if anyone has clarification appreciate it

Its ok I think I have it sorted

Its a SA100 and SA105 form I had to fill in
