I wouldn't worry about the TM30 unless you need something from immigration. It's not your responsibility anyway, it's the landlord. You just need it done before your 90 day and most hotels/guesthouses will do it without you asking. You can ask and confirm. Although I don't recommend it, and I would try to do them, if you are never doing an extension it is unlikely you would face any consequences for missing a 90 day report anyway, they don't care about it on exit or entry, only if you need to deal with immigration in country. I prefer to follow all regulations regardless but just pointing out. Worst case if it did come up it's a 2,000B fine, which never increases.
