Koh Phangan has its own immigration point in Thong Sala for the everyday errands - the 90-day address report and TM30 notification - but a full annual extension of stay, a certificate of residence or a re-entry permit usually still means a ferry to Koh Samui Immigration in Na Thon. Here is the expat guide to what each office handles, where they are, and how to keep the paperwork side of island life low-stress.
For anyone living on Koh Phangan on a long-stay visa - retirement, marriage, the DTV, the LTR, work or family - immigration paperwork is a recurring but manageable part of island life. Since May 2021, a local immigration point at the Thong Sala police station has handled the routine 90-day address report and TM30 notification that every long-stay resident owes, so most people no longer need to leave the island for those errands. For the more involved annual extension of stay, a certificate of residence, or a re-entry permit, the standard route remains a ferry to Koh Samui Immigration in Na Thon, the main office serving the whole Surat Thani Gulf-island group of Samui, Phangan and Tao. This guide covers what each office handles, where to find them, how each errand works, the four ways to file a 90-day report, why the TM30 matters so much, and how to stay clear of overstay.
If you live on Koh Phangan under a long-stay extension (retirement, marriage, DTV, LTR, education or work), you must report your current address to immigration every 90 days. The island's own immigration point at the Thong Sala police station on Chaloklum Road handles this routine report, so most residents never need to leave the island for it. You can also file by registered post 7-15 days before the due date, online through the immigration website or app once you are enrolled in the system, or through an agent. Missing it carries a fine, so diarise the due date printed on your receipt slip.
Thai law requires the 'house master' - your landlord, condo or villa owner, or hotel - to notify immigration that a foreigner is staying at their address, normally within 24 hours of you moving in or returning from abroad. The Thong Sala office processes TM30 filings for Koh Phangan addresses, and the resulting receipt is one of the most important documents you hold on the island: it is usually required before a 90-day report, an extension application, or a certificate of residence goes through. Confirm your landlord has filed it and keep a copy.
The renewable one-year extension of stay - the permission that turns a retirement, marriage, work or family visa into a real long stay - is a more involved application than a 90-day report, and Koh Phangan's small Thong Sala point offers only limited services. Most long-stay residents take the ferry to Koh Samui Immigration in Na Thon, the main office for the Surat Thani Gulf islands (Samui, Phangan and Tao), bringing financial evidence, TM30 receipt, passport, photos and the TM7 form. Confirm current requirements and whether Thong Sala can process your specific case before booking a Samui trip.
A one-year extension of stay is cancelled the moment you leave Thailand unless you hold a re-entry permit, and a certificate of residence - the letter proving your address - is needed for a Thai driving licence, a vehicle purchase or some bank accounts. Both are typically arranged at Koh Samui Immigration in Na Thon rather than the Thong Sala point, though it is worth asking locally first as service levels on the island have expanded over time. Either way, sort these well before you need to fly out or sit a driving test, since a ferry trip adds a day to the errand.
Koh Phangan's immigration point sits on the grounds of the police station on Chaloklum Road in Thong Sala, the island's administrative and commercial hub near the main pier. It opened to give islanders a local option for the most common errands - 90-day reporting and TM30 notification - without a ferry trip. For anything the local point cannot process, the next stop is Koh Samui Immigration in Na Thon on the west coast of Koh Samui, roughly a 30-45 minute ferry crossing from Thong Sala pier.
Both the Thong Sala point and Koh Samui Immigration run busiest first thing in the morning and around visa-run season. Arrive early, dress neatly for a government office, and if you are making the ferry trip to Samui, build in the crossing time plus transport to Na Thon on either side. Extensions in particular can require a second visit, so never leave the errand until the final days before your permitted stay expires - especially with a ferry crossing in the mix.
For a 90-day report, bring your passport, TM30 receipt and the completed TM47 form. Extension and certificate applications add financial evidence, photos, proof of address and the relevant form, and requirements are periodically tightened, so confirm the current checklist - either with the Thong Sala point or Koh Samui Immigration - before you go. Bring more photocopies than you think you need; losing your place in a queue to find a photocopier is an avoidable frustration on either island.
Because a full extension or certificate errand on Koh Phangan can mean a ferry trip to Koh Samui, many long-stay residents use a visa agent based on Phangan, Samui or in Surat Thani to prepare paperwork, handle the TM30, and make the Na Thon trip on their behalf. A routine 90-day report at the Thong Sala point rarely needs one, but for annual extensions an established agent can save a wasted crossing if paperwork is incomplete.
File your 90-day report in person at the Thong Sala immigration point (queue ticket, passport, TM30 receipt and TM47 form, then collect your receipt slip), by registered post sent 7-15 days ahead of the due date, online via the immigration website or app once enrolled, or through an agent. Leaving and re-entering Thailand resets the 90-day clock, and the next due date is printed on your receipt - keep it.
A certificate of residence confirming your Koh Phangan address is generally issued through Koh Samui Immigration in Na Thon and is needed for a driving licence, buying a vehicle, or some bank accounts. Some long-stay residents instead pursue a yellow house book and pink ID card as a reusable proof of address that avoids repeat trips - ask locally or through a visa agent about the current process for Gulf-island residents.
Overstay is fined 500 baht per day up to a 20,000 baht cap, and longer overstays can trigger a re-entry ban. Watch the permitted-to-stay stamp in your passport rather than your visa's validity date, and start any extension application early given the extra step of a possible Koh Samui trip. If you plan to travel, arrange your re-entry permit first - do not assume Thong Sala can issue one on short notice.
Confirm your TM30 is filed before you go, bring every document plus copies, and check current opening hours and exactly which services the Thong Sala point handles before you plan around it - services there have expanded since it opened in 2021 but still trail a full provincial office. If your errand needs Koh Samui, time it around the ferry schedule and treat it as a half-day trip. A Thai-speaking friend or a reputable Gulf-islands visa agent removes most of the friction for annual extensions.
Yes - a local immigration point operates on the grounds of the police station on Chaloklum Road in Thong Sala, open since May 2021. It handles the most common errands: 90-day address reporting and TM30 notification of residence. For a full annual extension of stay, a certificate of residence, or a re-entry permit, most residents still need to ferry to Koh Samui Immigration in Na Thon, the main office for the Surat Thani Gulf islands. Confirm current services locally before planning your errand, as the office's capabilities have grown since opening.
The Thong Sala immigration point at the police station on Chaloklum Road processes 90-day reports for island residents, so a ferry trip is not usually required for this errand. Bring your passport, TM30 receipt and a completed TM47 form. You can also report by registered post, online once enrolled, or through an agent. Leaving and re-entering Thailand resets your 90-day clock.
Likely yes for a full one-year extension of stay (retirement, marriage, work or family). The Thong Sala point on Phangan offers limited services, and Koh Samui Immigration in Na Thon - roughly a 30-45 minute ferry crossing away - is the main office serving Koh Samui, Koh Phangan and Koh Tao under Surat Thani province. Confirm with the Thong Sala office first, since which extension types it can process has changed since it opened.
The TM30 is the address notification your landlord, villa or condo owner, or hotel must file with immigration when you move in or return from abroad, normally within 24 hours. The Thong Sala immigration point processes TM30 filings for island addresses, and the receipt is usually required before a 90-day report, extension or certificate of residence will be accepted. Confirm your landlord or the property's management has filed it, and keep your own copy.
A one-year extension of stay is cancelled the moment you leave Thailand unless you hold a re-entry permit first. These are generally issued at Koh Samui Immigration in Na Thon rather than the Thong Sala point, so plan a ferry trip in advance of any international travel rather than assuming you can sort it locally at the last minute. You can also buy one at the airport you depart from, but arranging it calmly beforehand is far less stressful.
