FWIW one more experience, I went to my local tax-office outside Chiang Mai a week ago, and played old (which often helps, here) & stupid but willing, saying (well, it was true !) that my overseas-bank wanted to know my Thai T.I.N., so that they could send year-end information about me to Thailand.
They didn't speak much English, I (of course) don't poot much Thai, either.
They asked if I was married to a Thai, "Yes".
Did I live in my wife's house, "Yes".
They then asked did I have the house-papers, "Not with me, and anyway I'm not on them".
Did I have a copy of my marriage-certificate, "Not with me, Sorry".
At this point she spoke to her senior-officer, made a brief phone-call, took copies of my passport & visa & recent sole-name/offshore bank-statement which has my Thai residential-address.
Then punched my details into her computer, made me sign her book of newly-issued TINs, and handed me what I wanted ... a simple certificate (3-inches square) showing my name/address/new T.I.N !
I thanked her profusely, lots of wai-ing, and made my retreat.
At no time was I asked-for, or did I offer, to make an annual-return for 2024. Which would anyway have shown, that my local bank-interest & transfers-into-Thailand fell a few-thousand Baht short, of owing them any income-tax, for the year !
Result !
