Tax Question

I am a US citizen, and have just applied for British citizenship with form UKM. I live in the US and file US taxes. Once I become a British citizen, will I have to file UK taxes? I will still be living in the US.

As a US citizen, you are required to file taxes unless you are under the minimum threshold.  Becoming a British citizen does not affect this requirement.

I know I have to file US taxes. The question was do I have to file a UK tax return as a British citizen.

Oops, sorry!  No, there is no requirement as there is for US citizens.

You will only have to file UK taxes if you have investments and/or sources of UK income.

Thanks, everyone. That's what I thought. Just wanted to make sure

Actually UK law says there is a requirement to file a Return if there is a liability or reclaim: and although it's probably true to say that's likely if you have investment income or gains, it's also true if you have any earnings or pensions sourced from the USA. The safe way is to compute your UK tax liability every year - as required under self assessment - and then decide if you need to put in a UK tax return based on whether there is a balance due/reclaimable.

If the OP isn't a UK resident how can any US source income be liable to UK taxation?
