How can I obtain a Certificate of Residence from the Thai Tax Office as an Austrian pensioner in Kanchanaburi?

So far I did it all by myself after I got this paper as an example from another Dutch guy.

I transfer every month an amount in Euro to my Bangkok bank account as international transfer. That transfer amount in Thai Baht, I print every month. I made a spread sheet with those 12 amounts (to caculate my tax) and go to the Revenue office. They fill in a so called PND91 with the total year amount and the deductions (100k฿ for everyone, 60k฿ per family (official) member, only me in this case and 190k฿ deduction because I am 65 year plus). First tranch in their system of 150k฿ is zero %. So I have a total deduction of 500k฿. If you transfer e.g. 700k฿ in a year, than it's only 5% next 150k฿ and 10% over the last 50k฿. Then I pay and buy a legal copy of that PND91 for 18฿ 🤭. With that I could get that RO22 document. In another Revenue office though 🙄. I only need this document every 5 year to get tax exemption in the Netherlands.
