@Paul ******

while there is a legal requirement to register a stay at every new accomodation (within 24 hours) for foreign visitors using form tm30, there is no legal requirement to refile if you are returning to an accomodation where you have a registered stay and the stay period is still active, (eg your home with a null checkout date on the form). However, while its not a legal requirement, it can be a requirement of some IO's to refile an updated version prior to face to face interaction. This was a change to the law in i believe jun 21.

Sam Sam sorry, legally its not required if returning to the registered address within the valid check-in dates. However it is highly recomended if you need to interact with an IO to reregister and reprint it.

James Reid Patrick not that easy with regard Thailand, as it is only a remitence based tax system. You would require a zero rate tax code to be issued to you, which the UK tax office is very reluctant to issue to tax residents of remitence based tax regimes, where if you didnt remit all your income it wouldnt be taxed in either country.

You can pay your normal tax in UK, and then pay Thai tax on the remitted funds and then ask UK for a refund after the fact. But theres 'no opting out' as such.

Mark Wright while it is recomended, and certain offices require upto date tm30's when interacting with them, its not been a legal requirement since 2020 if returning to your normaly registered property within the registered check in period. .

Legal change effective mid-2020 clarified repeat filing

The regulation published on 16 June 2020 and effective 30 June 2020 amended how TM30 is handled:

Once a TM30 has been filed for a foreigner’s stay at a specific address, the owner does not need to re-submit a TM30 every time that foreigner leaves and returns to the same address as long as the stay remains within the original declared stay period in that TM30.

That means the same TM30 is legally considered valid for multiple entries and departures to and from that address, provided the original check-in/check-out dates declared haven’t expired.

This change was officially published in the Government Gazette — so it is not just immigration “policy” or local office practice, it’s a legal/administrative regulation that modifies how Section 38 is applied.

✅ 3. Applying that to your specific question

You asked:

When returning to your house from traveling abroad within the original registered stay/check-in period, is it legally required to file a new TM30?

Legal answer: NO — if:

A valid TM30 was already filed for that same address (with a declared stay period that covers the time you are returning), and

You are returning to that same address, and

You are staying within the stay period already declared in that TM30 submission, then

→ There is no legal requirement to file a new TM30 just because you left the country and returned.

This is because the 2020 regulation removed the need to repeatedly notify Immigration for the same foreigner/ same residence as long as the original stay declaration hasn’t expired.

⚠️ Important Legal Clarifications

The law does not oblige you to file it — it obliges the owner/landlord to file it.

If the declared “period of stay” in the original TM30 expires (e.g., you declared you would stay until date X), a new TM30 would be required if you are now residing past that date — because the previous declared period is no longer valid.

If you move to a different address (different residence), a new TM30 must be filed within 24 hours of arrival at that new address.

🧠 Summary — Strict Legal Position

Situation New TM30 legally required?

First arrival at your house and TM30 filed Yes (initial TM30)

Leave Thailand and return within the same declared period No

Leave Thailand and come back after the declared period has expired Yes

Move to a different residence Yes

Domestic travel and return to same address within declared period No

This is what the law/regulations actually say, regardless of some immigration offices enforcing other practices in reality.

If you want, I can also point you to the exact sections of the regulation in Thai text that show this rule — that’s the legally binding source.

Gary Colclough pretty much impossible to obtain a zero tax code in uk based on living and paying tax in Thailand. This is because in TH you only pay tax on the money you move here (if its assesable). So if you only moved half your pension here to live on, the part left in uk would end up un taxed which isn't allowed.

Legally, if you are returning to your previously recorded location within the check-in> check-out dates on the tm30 for that location, after any sort of travel, you do not have to file a new record.

For the sake of practibility its best to reregister at least once a year before your visa extension or where you may need to produce a copy to the IO.

Your house/condo should have null checkout date, making it an underlying permanent record, hotels fill in checkout dates creating temporary records which expire.

Terry Larcombe thats not a problem, on the 9th Feb you receive an under consideration stamp (permission to stay) until March 9th, and on 9th March you receive your extension until 25th Feb 2027.

I do it every year, jan 6th visa date, but dont request extension until Dec 24th giving me a pick up date of Jan 14th. The only watchout is absence of any re-entry permit you might currently hold between Feb 25th and March 9th.

The reset comment from the government was made with regards "extensions' (the new 30 & 7 max per year), not 'exemptions'.

A student visa is only required by those entering the country for the sole purpose of attending an education facility. Your son is entering as a dependant child presumably of school age, meaning there is an expectation he will attend some form of school to maintain his education. There are thousands of children of expats on various visa's here as dependants and attending schools no ed visa required. You yourself may decide to enroll in a school to learn Thai to ease your stay, you don't have to get a different visa for that.
