Just to clarify: so your bank provided a 12 month bank statement "on the spot"? Some banks can do that eg Kasikorn.
Others eg BBL cannot.
Re 90 day report a TM47 will be required for anyone that has been continuously for 90 days
Yes up to 45 days early.
I personally was asked for 12 month bank statement last 2 extensions.
However others have reported photocopies of bankbook pages sufficient.
I also use funds in bank method.
TM47 definitely required.
Re any other doc: some folk supply TM30. I never have. Note I do provide lease.
Re other passport page photocopies.
Go downstairs to copy/print places and hand over pp and say "retirement extension" they will copy what you need.

OP, you have zero concerns.
Which immigration office do you deal with?
Regarding 90 day report do that via mail or online.
Obviously using your registered address
Think you are asking where/how can you obtain a non O based on retirement.
That can be obtained at Thai consulate/embassy or from visa exempt or tourist visa entry at your local Thai immigration office
Repeating it was triggered by your comment that... TGF can "handle it" which I found sorta silly.
In face immigration will notice that you have previously had 12 month extensions based on retirement.
When living in Thailand ongoing some immigration officers don't like ongoing back to back entries.
Depends a lot on time spent out of Thailand.
Even roster workers month on/off can be hassled.
You stated in one part of the OP...
"wondering if I can expect any problems down the track if I ditch doing the yearly retirement extensions"
Sounds like a plan to me .."IF I ditch,"
My advice was bad move.
And you will eventually end up with problems.
I answered this in other thread you asked.
This attached thread seems to indicate almost extinct species.
Haven't even seen recent reports of them even from Savannakhet.
Places like London eVisa removed them from menu.
https://aseannow.com/topic/1313316-multi-entry-non-o-retirement-visa/
Multi entry non O retirement (one year visa) is available in very few places now.
Where would you be hoping to apply?
For a single entry non O you can obtain that in a Thai consulate/embassy (good option) or in Thailand from a visa exempt or tourist visa entry.
In the last 30 days of that 90 day stamp you can apply for 12 months extension however has financial requirements.
OP, this is a good suggestion.
If say 6 months is required then you could enter Thailand visa exempt and then obtain the non O at immigration followed by the 60 day extension.
Assume you have a Thai bank account in your name only
Yes he is correct.
You can obtain a 12 month extension of permission of stay.
If you are living ongoing in Thailand skip Savannakhet and do annual extensions of your permission of stay.
Think it's best idea.
Pick a time when you are pretty sure that you won't need to exit Thailand for travel..
Earlier post has thread that outlines process for pp renewal.
Why so needing to squeeze as much as possible out of a pp.
Guessing USA pp valid for 10 years.
Obtain a new one well before expiry.
Yes if not your next extension will have expiry date same as expiry of current pp.

The thing is many offices want a TM47 receipt.
Esp at eg CW where they have a doc check girl.
In my example my last report was 10 months ago. I will show that receipt and my pp can show due to travel no reporting was due in last 10 months.
Never continuously in country 90+ days
