I'm a non-resident, and have done SA the last few years - it's got to the point now where the tax I receive back is less than my costs of processing the SA.
Can I tell HMRC that I don't want to do it anymore?
I only have a few savings accounts in the UK, no real assets anymore.
Hopefully, they'll follow through and NOT issue you with a notice to complete a return. However, be careful because they don't always do what they say.
