Of all the paperwork that comes with retiring to Thailand, banking is the one that touches everything else. Your visa extension may depend on money sitting in a Thai account. Your rent, your electric bill, the noodle shop on the corner — all of it runs more smoothly once you have a local account and the bank's app on your phone. The good news is that none of it is hard. It is just particular: Thai banks work branch by branch, document by document, and the retirees who get sorted fastest are the ones who walk in prepared.
This is the list we wish someone had handed us in our first month — ten things to sort, in roughly the order you will need them, whether you settle in Phuket, up in Surin in Isan, or anywhere in between.
Opening the account
1. Pick the branch before you pick the bank
Thailand's big banks — Bangkok Bank, Kasikornbank (the green KBank), SCB, Krungthai and a handful of others — all offer perfectly good everyday accounts, solid apps and ATM networks that cover the country. The difference that actually matters day to day is not the logo. It is the branch. Account-opening rules for foreigners are interpreted locally, so one branch may open your account in twenty minutes while another across town asks for a document the first never mentioned. Choose a branch near where you will actually live, because that branch becomes your "home branch" for the bigger jobs later: replacing a lost book, certifying balances for immigration, and sorting problems in person. If you are splitting your year between two places, open the account where your visa business is done.
2. Walk in with the full document folder
Bring more than you think you need: your passport, your current visa or extension stamp, proof of your Thai address (a lease, a house book copy from your landlord, or a utility bill in your name), and — the one that unlocks most doors — a certificate of residence from your local immigration office. Some branches also ask to see a Thai phone number that is registered in your own name, so have your SIM sorted first. Dress neatly, go on a weekday morning, and be patient and polite; in Thailand that combination opens more accounts than any argument about policy. If one branch says no, thank them and try another branch of the same bank before you give up on it — this is normal, not personal.
3. Understand what the account is for: your visa money lives here
For most retirement extensions, immigration wants to see money seasoned in a Thai bank account in your name only — the figure most applicants know is 800,000 baht held for the required period, or a monthly-income route, depending on your visa type and nationality. Rules and seasoning periods change, and embassies and immigration offices do not always read them the same way, so treat any number you read online (including here) as a prompt to confirm the current rule at your own immigration office well before renewal time. The practical point stands either way: open the account early, keep the visa money separate from your spending money if you can, and never let the balance dip below the required line in the months before your extension.
4. Get the app, the card and the bank book — all three
Thai banking still runs on a paper passbook alongside the app, and you will want both. The passbook is what immigration photocopies; the app is what you will actually use every day. Before you leave the branch, have the staff help you activate mobile banking on your phone, set your PINs, and make one small test transfer while you are standing there. Ask for a debit card too, even if you mostly pay by phone — it is your backup at ATMs and in bigger shops. Photograph the front of your bank book and keep the photo somewhere safe; the account number in that book is the one detail you will be asked for again and again.
Moving money in from home
5. Send your pension like a local, not like a tourist
Once the account exists, the monthly rhythm begins: pension or savings in, Thai life out. Most long-stayers move money with a specialist transfer service such as Wise rather than a traditional bank wire, because the exchange rate is usually the real mid-market rate and the fee is shown up front — but compare on the day, every time, on the total baht that lands, not on the headline fee. Keep transfers regular and boring: the same sort of amount, around the same time each month. If you ever use the income method for your visa, that steady pattern of foreign transfers, clearly coded as coming from abroad, is exactly what immigration wants to see, so keep your transfer receipts.
6. Keep your home account and cards alive
Do not burn the bridges behind you. Keep at least one account open back home with online access, a working card, and your home-country phone or authenticator app still able to receive its security codes. You will need it for tax matters, for subscriptions that insist on a home address, for the occasional big purchase, and as your emergency back door if a Thai card is ever swallowed by an ATM on a Sunday night. Tell your home bank you live in Thailand before you move, not after their fraud system discovers it for you.
7. Build a two-pot system: visa money and living money
The retirees who sleep best tend to run two pots. Pot one is the visa account: it holds the seasoned balance, it is touched as little as possible, and some people keep it at a different bank entirely so there is no chance of an absent-minded transfer dipping it under the line. Pot two is everyday money: rent, food, fuel, fun. Top it up monthly from home and spend it down without anxiety. Two pots turn the annual extension from a scramble into a photocopying exercise, and they make your monthly budget almost embarrassingly easy to see at a glance.
Surin money or Phuket money? Banking where you actually live
Where you open the account matters more if you split your life the way we do — between Surin, up in Isan, and Phuket, where the work is. In Phuket, especially around Patong, Phuket Town and the big malls, you will find branches of every major bank, staff who deal with foreigners daily, and immigration paperwork that surprises nobody. In Surin and other smaller Isan cities the same big banks are all present — this is not the back of beyond — but foreign customers are fewer, so the certificate of residence and a lease in your name carry even more weight, and a smile and a weekday morning carry the rest. The apps, the ATMs and PromptPay work identically in both places; a baht in Surin spends exactly like a baht in Patong, it just tends to go noticeably further at the market.
One more local habit worth copying early: keep your paperwork the Thai way. Thais keep folders — real folders — with photocopies of passport pages, visa stamps, the bank book, the lease and the house registration of wherever they live. Start your own folder in month one and add to it every time a stamp, a receipt or a certificate crosses your path. Half the errands of Thai life, from opening this account to renewing your extension to registering at a hospital, become five-minute jobs when the folder is already in your hand, and half-day sagas when it is not. It is the cheapest, dullest, most valuable retirement habit on this entire list.
Everyday money, the Thai way
8. Learn PromptPay and QR — Thailand barely uses cash or cards now
The single biggest surprise for new arrivals is how completely Thailand has gone QR. Market stalls, coffee carts, pharmacies, taxis, the lady selling bananas from a sidecar — all of them display a PromptPay QR code, and you pay by scanning it with your Thai banking app. No fee, no minimum, no fumbling for change. Link PromptPay to your account as soon as the app is live, practice on small purchases, and always check the shop's name and the amount on your screen before you confirm. Within a month you will find your wallet getting lighter and your coin tray at home getting strangely full.
9. Cash is still king in the small places — carry some, wisely
QR has not reached everywhere. Temple fairs, village markets up in Surin, the songthaew driver, the man who fixes your fan — cash still talks, and small notes talk best. Keep a modest float of 20s, 50s and 100s at home, use ATMs attached to bank branches where you can (a human is nearby if the machine misbehaves), and remember that foreign-card ATM withdrawals here carry a flat local fee per withdrawal, so fewer, larger withdrawals cost less than daily small ones. Never carry your whole month's money on a night out; Thailand is kind, but wallets are forgetful everywhere on earth.
10. Protect yourself: the boring security habits that matter
Thai banks will never phone you and ask for a code, a PIN or a password — anyone who does is a thief, full stop, however official they sound. Turn on transaction alerts in the app so every movement pings your phone. Set a sensible daily transfer limit; you can raise it in the branch the one day a year you actually need to move something big. Keep your banking app behind your phone's fingerprint or face lock, and keep a note — on paper, at home — of your bank's real hotline number from the back of your card, so if anything ever looks wrong you are calling the bank, not a number from a text message.
A simple first-month checklist
And one last encouragement, because almost everyone puts this job off: the whole thing is smaller than it looks from outside. Most retirees we know were fully banked — account open, app working, first transfer landed, first QR paid at a market stall — inside a single week, and the ones who took a month mostly took it in queueing time spread across three short mornings, not in difficulty. Staff in Thai bank branches do this all day, every day; a prepared foreigner with a tidy folder is an easy customer, not a problem. Start on a calm weekday, finish before lunch, and go and celebrate with something cold by the water. You have earned it, and you will have paid for it by QR.
In order, then: get your Thai SIM in your own name; get your certificate of residence; choose your home branch; open the account with the full document folder; activate the app, card and PromptPay before you leave the branch; make your first transfer in and keep the receipt; set up the two pots; and file the passbook somewhere you will find it again in eleven months, because extension season comes around faster than you think. Do those things in your first month and Thai banking quietly stops being a topic at all — it just becomes how the days work, from the morning market QR to the pension landing in your account while you are still asleep. Which is exactly what retirement here is supposed to feel like.
