Marriage Visa Money: The 400,000 Baht Requirement Explained

Marriage Visa Money: The 400,000 Baht Requirement Explained

The Thai marriage visa (technically a Non-Immigrant O visa based on marriage to a Thai national) needs one of three financial proofs: ฿400,000 (~$12,120) sitting in a Thai bank account in your own name, ฿40,000/month (~$1,210) in verifiable income, or a combination of the two that adds up to ฿400,000 a year. The number that trips people up is not the amount, it's the timing: the money has to be seasoned, meaning it sits untouched in the account for a set period before you apply.

Seasoning works differently depending on where you are in the process. Before your first Non-O application, the ฿400,000 needs to have been in the account for at least 2 months. Before every annual extension after that, immigration wants at least 3 months of seasoning. Miss that window with a lump-sum deposit two weeks before your appointment and the officer will reject it, no matter how much money is sitting there.

Quick answer: the three financial routes

• Bank route: ฿400,000 (~$12,120) in a Thai bank account, own name, seasoned 2 months before the first application, 3 months before each extension.
• Income route: ฿40,000/month (~$1,210) in verifiable income, evidenced by 12 months of bank statements showing regular incoming transfers or a home-country income letter.
• Combination route: deposit + annual income that together reach ฿400,000/year (e.g. ฿200,000 in the bank plus ฿20,000/month, or ฿160,000 plus ฿20,000/month for 12 months).
• No health insurance requirement — unlike the retirement O-A visa, the marriage-based Non-O does not require proof of medical insurance.
• Extension fee: ฿1,900 at Thai immigration, paid annually alongside the financial proof.
• A one-day dip below ฿400,000 during the seasoning window can restart the clock — treat the balance as frozen, not spending money.

The bank deposit route in detail

The most straightforward path is a single Thai bank account holding ฿400,000 or more, in the applicant's own name (not the Thai spouse's account, and not a joint account in most immigration offices' reading of the rule). The account needs to be with a Thai bank, and it needs a passbook or statement immigration officers can physically stamp or photocopy on the day.

Seasoning is the part people underestimate. For a first-time application, the money must have rested in the account for at least 2 months before you submit. For every annual extension after that, immigration raises the bar to at least 3 months, applying every single year you renew. Officers check the passbook's transaction history, not just the current balance, so a single large transfer that arrived last week and pushed the balance over ฿400,000 will not pass, even if the balance has technically been above threshold since that transfer.

The safest practice: keep the account at ฿400,000 or higher continuously, never letting it dip below that line even for a day to cover an unrelated bill. If you need spare cash for holidays or a condo deposit, hold it somewhere else and treat the visa account as untouchable.

The income route in detail

Instead of a lump sum, you can show ฿40,000/month (~$1,210) in income, evidenced either by a formal income letter from your embassy or 12 months of Thai bank statements showing regular incoming transfers of at least ฿40,000 a month.

The embassy letter has gotten harder to obtain. Several embassies, including the US, UK and Australian embassies, have stopped issuing the income-verification letter that Thai immigration traditionally accepted, pushing more applicants toward the bank-statement route by default. If your embassy still issues one, it typically needs a supporting affidavit and can take weeks to arrange. If it does not, plan on a full year of clean, regular transfers into a Thai account before you can rely on the income route alone.

The combination route

If you don't have the full ฿400,000 sitting idle and don't clear ฿40,000/month either, immigration accepts a blended calculation: a smaller deposit plus a smaller monthly income that together reach ฿400,000 over the year. A commonly cited example is ฿200,000 in the bank plus ฿20,000/month in income, but the math is flexible as long as the annual total clears ฿400,000. Some offices calculate it as deposit + (monthly income × 12), so run the arithmetic with your specific numbers before you commit to a plan, and confirm the exact formula your local immigration office uses, since interpretation varies slightly by office.

What the marriage visa does NOT require

Unlike the retirement-based O-A visa, the marriage Non-O has no mandatory health insurance requirement. That's a real gap: if something goes wrong medically, you're exposed to Thailand's private hospital pricing, which is not cheap and often not itemized clearly in advance. Most people on this visa still buy their own cover; see the comparison of SafetyWing, Genki and Cigna for what a policy costs at different ages.

There's also no lump-sum "elite" buyout option here the way there is with the Thailand Elite program — the financial test is fixed at ฿400,000 or the income equivalent, regardless of how much money you actually have.

Fees and ongoing costs

The extension itself costs ฿1,900, paid at Thai immigration alongside your financial documents each year. On top of that, budget for a re-entry permit if you plan to leave and return during your permit-to-stay, and mandatory 90-day address reporting, which is free if done on time but carries a 2,000 THB fine for reporting late in person. None of these figures move the needle compared to the ฿400,000 seasoning requirement itself, but they add up over a multi-year stay.

How this compares to other Thai visa money rules

The ฿400,000 marriage threshold sits below the retirement visa's ฿800,000 deposit or ฿65,000/month income test, since a Thai spouse is treated as a lower-risk sponsor than a solo retiree. It's also well below the DTV's ฿500,000 liquid-funds requirement, a different category entirely (remote-work focused, not marriage-based) with its own 3-month seasoning rule and near-universal bank account refusals for DTV holders. Run your numbers through the DTV funds checker or the cost-of-living calculator before picking a visa path.

Tax note for marriage-visa holders

Holding a marriage visa does not change your Thai tax exposure. Spend 180 days or more in Thailand in a calendar year and you become a Thai tax resident, meaning any foreign-sourced income you remit into Thailand is assessable under the current remittance rule (Por 161/162, effective 1 January 2024). This is the live law right now — a 2025 proposal to exempt foreign income remitted within two years was never enacted and is frozen pending the new government formed after the 8 February 2026 election. Track the live status on the Thailand foreign income tax status tracker before moving large sums into your visa account, and confirm separately whether you need a Thai tax ID.

Frequently Asked Questions

Can I use my Thai spouse's bank account for the 400,000 baht requirement?

No, in almost all immigration offices the money needs to be in the foreign applicant's own name, not a joint account and not the Thai spouse's sole account. Some offices have shown flexibility on joint accounts, but the safe, universally accepted route is a Thai bank account held solely by the foreign spouse.

Does the 400,000 baht have to be a lump sum, or can I build it up over time?

You can build it up, but the balance needs to have been at or above ฿400,000 continuously for the required seasoning window (2 months for a first application, 3 months for each extension) before your appointment. A recent lump-sum deposit that only just crossed the threshold will likely be rejected even if the current balance looks fine.

What happens if my balance dips below 400,000 baht during the seasoning period?

It resets the clock in most cases. Immigration checks the passbook transaction history, not just the balance on the day you apply, so a dip below threshold during the seasoning window can force you to wait out a fresh 2- or 3-month period before reapplying.

Do I need health insurance for a Thailand marriage visa?

No. Health insurance is not a requirement for the Non-O marriage visa or its extensions, unlike the retirement O-A visa which mandates coverage. It's still strongly recommended given how expensive Thai private hospital care can get without cover.

The bottom line

The marriage visa's ฿400,000 threshold is one of the more forgiving financial tests in the Thai visa system, but the seasoning rule is where people get caught out. Park the money at least 2 months before your first application, keep it above ฿400,000 continuously, and give yourself 3 full months of clean history before every extension after that. If you're choosing between the bank, income, or combination route, pick the one you can document cleanly for a full year, not just the one that's easiest to fund today.
