Filing employee personal details in HMRC starter checklist

Hello. I am starting my first employment with a UK-based company and I am currently residing in the UK. I was asked by my employer to complete the HMRC starter checklist. I am wondering about providing info under the last and first name columns HMRC starter checklist. I do not have a last name in my Indian passport and in my UK BRP, my last name is mentioned as a single line. How do I fill the last and first name columns in the HMRC starter checklist? Any guidance will be helpful.

Hi,

If you have registered for a National Insurance number then how this has been noted would be the information we would require. If not, how will your employer be noting you on their systems, will they be using a first name/surname? If so, you should use the same format as that so when they provide us your pay and tax information it will link up. You can see information here:

Thank you.
