Apologies if it is actually simple but after a lot of homework done I am still completely stumped on the following aspect after I relocated this tax year to non-UK address:

1. I should and apparently can change my main address & correspondence address to my new non-UK address (no longer own a home in UK) on their online portal,

2. BUT the SA109 form for tax residence is only possible to file for previous tax year - therefore, I can only file it after this tax year. Everything says it must be filed "when" I move out of the UK but this is impossible - as it refers always to previous tax year and it makes sense due to numerous residency tests.

So... having filed my self-assessment for previous tax year, can I just change address on their portal (so that it matches what private pension admins and other institutions have) then let them know about tax residence aspects much later i.e. in the next tax year via SA109?

Thank you, as it has been doing my head in and keep circling re-re-reading all the relevant materials.

It was so spot-on back then... but looks and sounds eerily prophetic in 2026... With everything that went down in just the last few years, this is painfully revoltingly accurate.

Just before I left the UK, I sold the car, too. As time was of essence, I sold it to Webuyanycar's local branch that is located inside a retailer's time-limited car park.

Weeks after the morning appointment & sale a parking fine reaches me for overstaying. The Webuyanycar employee drove out of the car park with my car more than 8 hours after I sold it, as per evidence, thus triggering their time limit enforcement with cameras.

NOTE: there was and is no process nor capability for my "logging" of the special case with them, buyer has to resolve this hardly unique situation based on whatever process and agreement they have. Clearly, they screwed this up.

I now appealed from abroad, also submitted change of liability request but...:

- the car park company shows no lifesigns (it can take 28 days and may decide to ignore all filed evidence, why not...),

- the local Webuyanycar branch does not respond to phone calls, voice mail, nor to emails sent to their specific address,

- and central Webuyanycar "customer support" email resulted in a response where they casually asked me to let them know of the appeal outcome. ZERO active involvement based on my attached documents, they sit back and twiddle thumbs, of course.

So the expat-related question: if this becomes a total mare, i.e. car park company rejects appeal despite proofs on the timeline, plus Webuyanycar obviously washes their hands... What can really happen? I could ignore it all and have a laugh but I tried to be stupidly responsible via all official channels - and now ended up stressed out like hell.

All my family and friends are laughing that I even bother to handle this from afar and spent days filing all kinds of emails, appeals, phone calls made... but... while this is totally absurd and stressing me out, what is worst case scenario here?
