If you searched TDAmeritrade Singapore expecting to open an account, here is the blunt answer: you cannot. TD Ameritrade Singapore Pte. Ltd. was renamed Charles Schwab SG Pte. Ltd., and the last TD Ameritrade accounts moved across to Schwab in May 2024. The brand is retired. The twist that almost nobody mentions until you are deep in the sign-up flow is that Schwab Singapore now accepts accredited investors only. If your income is below S$300,000 a year and your net financial assets are below S$1 million, the door is shut. The good news: the thinkorswim platform survived the move, and there are cheaper, retail-friendly brokers built for Singapore. This guide covers the real 2026 status, the eligibility numbers, the fees, and the alternatives worth your time.
Charles Schwab agreed to buy TD Ameritrade back in 2020. For a few years the two ran in parallel while accounts and systems were stitched together. In October 2023, TD Ameritrade told retail clients it would stop serving them. The automatic transfer of accounts to Schwab completed on 10 May 2024, and after that the TD Ameritrade login simply stopped working.
The Singapore entity went through the same transition. TD Ameritrade Singapore Pte. Ltd. is now legally Charles Schwab SG Pte. Ltd. If you held a TD Ameritrade account here, it was migrated automatically. You did not need to re-paper everything, but you do log in through Schwab now, and any options, futures, or forex approval levels carried over.
So when people type tdameritrade singapore into Google in 2026, they are searching for a product that no longer takes new sign-ups under that name. The question worth answering is not how do I open TD Ameritrade, it is can I open the thing it became, and the answer depends entirely on how wealthy you are.
This is the part that trips up most people. Charles Schwab's Singapore office services accredited investors. It does not accept applications from ordinary retail investors. If you do not qualify, or do not want to opt in to accredited investor status, Schwab's own guidance is to close the account.
Accredited investor is a formal status defined by the Monetary Authority of Singapore, not a label Schwab made up. You have to meet at least one of three thresholds and prove it with documents. These are high bars by design, because accredited investors get fewer regulatory protections in exchange for access to a wider product set.
If you are a typical working adult in Singapore building a portfolio with a few hundred or few thousand dollars a month, you are almost certainly not an accredited investor, and that is fine. It simply means the broker formerly known as TD Ameritrade is not for you. Trying to inflate figures to squeeze through is a bad idea: you would be giving up MAS retail protections for a platform that has cheaper, better-suited rivals locally. If you are still learning the ropes, our walkthrough on how to start investing in Singapore is a more useful starting point than chasing a closed door.
The single best thing TD Ameritrade ever shipped was thinkorswim, the desktop, web, and mobile trading suite that active traders loved for its charting and options analytics. The fear during the merger was that Schwab would kill it. It did not. thinkorswim lives on as Schwab's advanced platform, and migrated clients kept their saved settings and watchlists.
Two practical points. First, thinkorswim is overkill for buy-and-hold ETF investors; it is built for active options and futures traders. Second, it is only relevant to you if you can actually open a Schwab account, which loops back to the accredited investor wall above. The platform surviving is good news for high-net-worth traders and irrelevant for everyone else.
For those who clear the accredited investor bar, the pricing is genuinely competitive and inherited the best of TD Ameritrade's structure. As of June 2026, Schwab International charges no commission on online-listed US stock and ETF trades, US$0.65 per options contract, and has no minimum deposit or account maintenance fee for a standard brokerage account. Always confirm the live numbers on Schwab's own pricing page before you act, because broker pricing shifts.
Note that commission-free does not mean cost-free for a Singapore investor. US tax follows you regardless of which US broker you use, and that is covered further down. Before you compare any broker on headline commission alone, it helps to understand what an expense ratio and total cost of ownership actually look like across a year of trading.
Because Schwab Singapore is closed to retail, the practical question is which broker gives you US-market access without the accredited investor gate. The three names most Singapore retail investors land on are moomoo, Tiger Brokers, and Interactive Brokers. All three let ordinary investors open an account and buy US shares, and all three undercut traditional brokerages on fees.
Figures below are as of June 2026 and are headline minimums; brokers run frequent promotions and tiered pricing, so verify on each provider's pricing page. We have deeper write-ups on moomoo, Tiger Brokers, and Interactive Brokers if you want the full fee breakdown for each.
| Broker | Open to retail? | Headline US stock cost | Best suited to |
|---|---|---|---|
| Charles Schwab SG (ex-TD Ameritrade) | No, accredited investors only | US$0 commission, US$0.65/options contract | High-net-worth active traders |
| moomoo SG | Yes | US$0 commission + US$0.99 platform fee per order | Cost-conscious beginners |
| Tiger Brokers SG | Yes | From ~US$1.99 minimum per trade (per-share pricing) | Active multi-market traders |
| Interactive Brokers | Yes | From US$1 minimum per trade (tiered/fixed) | Larger, multi-currency portfolios |
This applies to any Singapore investor holding US-listed shares, whether through Schwab, moomoo, Tiger, or IBKR. Singapore has no dividend tax treaty with the United States, so US dividends are hit with a flat 30% withholding at source. You file a W-8BEN form to confirm you are a non-US person; it does not reduce the 30% dividend rate, but it does keep you out of US capital gains tax.
The bigger trap is US estate tax. For a non-resident, only the first US$60,000 of US-situated assets is exempt, and that figure has not changed since 1976. Above it, your estate can face US estate tax at rates up to 40% on US-listed holdings. A common structural fix is to hold Ireland-domiciled UCITS ETFs instead of US-domiciled ones, which sidesteps US estate tax exposure and cuts fund-level dividend withholding to 15%. If you are weighing fund routes, our ETF versus unit trust comparison lays out the tradeoffs.
None of this is a reason to avoid US markets. It is a reason to size your US-domiciled exposure deliberately and to know the rules before your portfolio crosses US$60,000 in US-situated assets.
Your next move depends on which camp you are in. The decision is short.
No. TD Ameritrade Singapore was renamed Charles Schwab SG, and the brand was fully retired after accounts migrated in May 2024. New US-investing accounts in Singapore now go through Schwab, which accepts accredited investors only.
It was transferred automatically to Charles Schwab. You now log in through Schwab rather than the old TD Ameritrade site, and your trading approval levels carried over. If you no longer meet accredited investor requirements, Schwab may require you to close or transfer the account.
Yes. thinkorswim survived the acquisition and is now Schwab's advanced trading platform across desktop, web, and mobile. Migrated clients kept their settings. It is only useful to you if you qualify to open a Schwab Singapore account, since the broker is accredited-investors only.
Retail investors who cannot meet Schwab's accredited investor bar typically use moomoo, Tiger Brokers, or Interactive Brokers. All three are open to retail, allow US share trading, and charge far less than legacy brokerages, with headline US stock costs starting around US$0.99 to US$1.99 per order as of June 2026.
