The short answer

For a large transfer, plan the South African side as carefully as the rate: work out how much falls within your R2 million allowance, apply for SARS approval for the rest weeks in advance, check your bank's limits, and have source-of-funds evidence ready. Send on a weekday morning, well clear of South African and Thai holidays. On the Thai side, send to an account in your name with the purpose stated, and expect the bank to ask for documents on larger sums. Above all, don't accept your bank's rate on a seven-figure sum: get a quote from an FX specialist such as Vita Capital, our FX partner, who handles transfers of all sizes and can fix or target your rate.

How much you can send, and how

Exchange control decides the ceiling before your bank's limits come into it. Allowances run from 1 January to 31 December and apply to each adult South African resident.

SARS and Reserve Bank rules (2026). Standard Bank's terms, for example, say app payments count against the discretionary allowance, and investment-allowance payments need a branch or bureau de change visit. A married couple each have their own allowances.

Bank limits on large payments

Before you book a rate, check how much your bank will let you send — and when.

FNB limits and fees via Wise ZA (30 September 2026); Standard Bank international payment terms for residents and Forex Pricing Guide 2026; Absa via Wise ZA (September 2026); Capitec bank charges (from 1 March 2026). Limits change and vary by account; check your own before you book a trade.

Four ways to plan around the limits

Our recommended routes for large transfers

Our number one for large sums, our number-one offshore account, a Thai bank for receiving, and a flat-fee bank for the smaller pieces.

How a large transfer works with a specialist

1. Talk through the plan — the amount, the purpose, the deadline, your allowances and how you'll fund it.
2. Sort out SARS approval for anything above your discretionary allowance, before you trade.
3. Complete the checks — identity and source of funds, done once before you trade.
4. Book the rate — spot for now, a forward for a future date, or a limit order for a target.
5. Fund the trade by the agreed deadline, with the balance-of-payments declaration.
6. The baht or foreign currency is paid to your Thai account, a seller or a developer.
7. Collect the confirmation and the Thai bank's paperwork for your records.

The order matters: know how you'll fund it — and that the allowance or approval is in place — before you book. A booked trade is binding, and if you can't send the money in time, you can face a loss if the rate has moved.

Source-of-funds evidence

Every regulated provider must know where a large sum came from. Your South African bank will ask, SARS will want to see your tax affairs in order for an approval, and the Thai bank may ask too. Have the evidence ready before you start, in one folder:

• A house sale — your conveyancer's statement on registration.
• Savings — statements showing how the balance built up.
• A retirement lump sum — the fund's payment letter and tax directive.
• An inheritance — the liquidation and distribution account or executor's letter.
• A business sale — the sale agreement and payment confirmation.
• Investments — the sale confirmation and statement.
• A gift — a letter from the giver and their own evidence. Donations tax may apply in South Africa above the annual exemption.
• Your ID, proof of address and tax number, in date.

Timing a large transfer

A large payment can be delayed by things that never affect a small one. Plan around them.

General guidance. Standard Bank's terms say international payments take at least two business days. Your provider confirms value dates and funding deadlines when you book.

Receiving a large sum in Thailand

• Use an account in your own name, with the name spelled exactly as on the transfer.
• State the purpose — "retirement savings", "purchase of condominium unit", "living expenses".
• Expect document requests on larger sums — SCB, for example, asks for supporting documents from USD 50,000.
• For a condo, receive foreign currency — usually US dollars — so the bank converts it and issues the FET form.

Tell your Thai branch in advance if you can. A large deposit arriving unexpectedly is more likely to be queried, and a branch that knows it's coming can have the paperwork ready. Our guide to SWIFT transfers to Thai bank accounts covers the receiving side.

A worked example: R5 million from a house sale

One way to move R5,000,000 over a few months, splitting it between tools and allowances rather than converting everything on one day. Illustrative rates from ฿2.04 today.

Illustration before any provider margin. Forward rate from the interest-rate difference (South Africa 7.25%, Thailand 1.00%). Limit orders aren't guaranteed to fill. A couple could send the first R4 million under two discretionary allowances. Specialist rates are quoted — ask Vita Capital for yours.

One transfer or several?

For a condo, each tranche of purchase money needs its own FET form or credit advice — keep them all. For savings, a single well-timed transfer or a planned series both work; with the rand moving more than 9% within 2026, many people prefer to spread the timing. A specialist can help you decide.

Baht, dollars or an offshore account?

With a large sum, it's worth deciding what form the money should take once it leaves South Africa.

Couples, joint money and other people's money

Large sums often belong to more than one person — a couple's house sale, a joint investment, money from a parent. That's fine, but the names on each end of the transfer need to make sense together.

• Each spouse has their own allowances. Send each person's share from their own account under their own allowance or SARS approval.
• Match the names. Money from one person's account to a Thai account in another's name may raise questions; tell your provider and the Thai bank who owns it.
• For a condo, send from the buyer. If the unit will be in one name, the purchase money should come from that person's account — check with your lawyer.
• Gifts need paperwork — a gift letter and the giver's source-of-funds evidence — and donations tax may apply in South Africa.

Your FX specialist will ask about all of this at the start. Being clear up front avoids the most common reason for a large payment being held: a name that doesn't match.

Tax and the paper trail

A large transfer is also a large entry in your financial history. While you remain a South African tax resident, SARS taxes your worldwide income and gains — and a house sale may carry capital gains tax. If you're also tax resident in Thailand — 180 days or more in a year — foreign income earned from 2024 onwards that you bring into Thailand can be taxable here, subject to the South Africa–Thailand tax treaty. Savings built up before 2024 are treated differently, but only if you can show it.

That makes the paper trail valuable: the conveyancer's statement or savings statements that show where the money came from and when, your SARS approval, the transfer confirmation, and the Thai bank's credit advice or FET form. Keep them together, scanned and on paper, and take advice before moving a large sum if you're already living in Thailand. Our guide to receiving overseas income in Thailand explains the rules.

After the money arrives

• Check the amount against your confirmation the day it lands, and query any shortfall at once.
• Update your passbook and ask for a credit advice or bank letter while it's fresh.
• Move what you don't need day to day into a separate savings or fixed deposit account.
• File every document — you'll need them for visas, tax, a purchase and, one day, sending money back.

Fraud and payment holds

Large international payments are exactly what fraudsters target — and exactly what banks scrutinise. A legitimate payment may be held while your bank calls you to check. That's a good thing; answer quickly and have your paperwork to hand. Recalls aren't guaranteed once money has left, so the checks before sending matter most.

• Never act on changed bank details sent by email or message — confirm by phone on a number you already have.
• Only pay the client account named in your provider's own confirmation.
• Never share an OTP, and protect your South African number against SIM swaps.
• Use a private, protected connection when banking from hotels and cafés in Thailand.

Our guide to payment scams covers the warning signs.

Questions to ask before a large transfer

• How much falls within my allowance this calendar year, and do I need SARS approval?
• What's my bank's limit for this payment, and at what times?
• What's the funding deadline once I book?
• What source-of-funds evidence will you need?
• How far is your rate from the market rate, and what will arrive?
• Should I split it between spot, a forward and a limit order?
• What will the Thai bank need to see on arrival?
• How is my money held between sending and delivery?

Mistakes with large transfers

1. Booking a rate before SARS approval is through.
2. Accepting the bank's rate on a seven-figure sum.
3. Sending in the afternoon or on a Friday, or just before a holiday.
4. Not having source-of-funds evidence ready, so the payment stalls.
5. Sending baht for a condo when foreign currency is needed.
6. Converting everything on one day without considering a forward or limit order.

How we researched this guide

We used Standard Bank's terms and conditions for international payments by South African residents, FNB's online limits and fees as published by Wise ZA (30 September 2026), Standard Bank's 2026 Forex Pricing Guide, Capitec's 2026 bank charges, SARS and Reserve Bank rules on allowances, SCB's SWIFT inward remittance terms, ThaiLawOnline's guide to the FET form, and Vita Capital's own published information on its private client services (October 2026). South African banks don't publish their exchange-rate margins, so the 3% margin is an illustration. Worked examples use ฿2.04 = R1 (22 October 2026) and are illustrations, not quotes. Vita Capital is JLIT's FX and escrow partner, and we can arrange Standard Bank Offshore accounts; we may receive a fee, which never changes the rate you're quoted. Checked 23 October 2026.
