Thailand Marriage Visa: The Financial Requirements
Of all the requirements for a Thailand marriage visa extension, the financial threshold is the one that causes the most confusion, and the most rejected applications. It sounds simple on the surface: 400,000 THB in the bank, or 40,000 THB a month in income. In practice, how that money is held, where it comes from, and how long it has been sitting there all matter just as much as the amount itself.
The Two Ways to Qualify
Thai Immigration accepts one of two routes to meet the financial requirement for a marriage based extension:
400,000 THB deposit held in a Thai bank account
40,000 THB per month in verifiable income
The requirement must be met in full through one method or the other. Immigration offices in our own service area do not accept a blend of the two, so plan around whichever single method actually fits your situation, rather than trying to combine a smaller deposit with a smaller income.
Method 1: The 400,000 THB Bank Deposit
The deposit must be held in a Thai bank account, in your own name only. A joint account with your spouse is generally not accepted for this purpose; immigration wants to see the funds clearly attributed to the foreign applicant.
The money needs to have been sitting in that account for at least two full months before your first application. At each annual renewal after that, many immigration offices ask for three months of seasoning instead of two, even though this is stricter than the underlying rule technically requires, so it is worth confirming with the office handling your file rather than assuming two months will always be enough.
The seasoning period is not the end of the story. Immigration reserves the right to check your account history at any time, and several offices expect the balance to remain reasonably intact well beyond your application date, not just long enough to pass the appointment. Depositing the full amount right before applying, then withdrawing most of it shortly after, is one of the most common reasons an account draws scrutiny at the next renewal.
Method 2: 40,000 THB Monthly Income
This route traditionally required a letter from your embassy in Thailand affirming your income. That option has narrowed considerably in recent years: the embassies of the United States, the United Kingdom, and Australia, among others, no longer issue these income affidavits.
Where that letter is unavailable, most immigration offices now accept twelve months of actual bank transfers into your Thai account, each showing at least 40,000 THB arriving from abroad, as proof of income instead. This is generally easier to prepare consistently than it sounds, since it simply means keeping a regular paper trail of your existing income rather than requesting a document from an embassy that may no longer provide it.
If your income arrives in a foreign currency, build in a buffer rather than calculating to the exact minimum. A monthly income that converts to exactly 40,000 THB today can easily convert to less after a shift in the exchange rate between now and your appointment. Aim comfortably above the threshold, not exactly at it.
Common Mistakes With This Requirement
Using a joint account. Funds held jointly with your Thai spouse are generally not accepted as meeting the deposit requirement on their own.
Treating the deposit as a one time event. Moving money in only to move it back out shortly after approval creates a pattern immigration officers do look for at your next renewal.
Assuming your embassy still issues income letters. Several major embassies have stopped, and finding this out at the immigration counter rather than beforehand costs you a wasted trip.
Using a foreign bank account for an in-country renewal. Only a Thai bank account counts once you are extending your stay from inside Thailand, regardless of what was accepted for your original visa abroad.
Cutting an income calculation too close to the minimum. A monthly transfer that clears 40,000 THB today can fall short by the time of your appointment, purely due to exchange rate movement.
This is exactly why we check all of this before you ever set foot in an immigration office.
