Thailand has long been a magnet for Australians looking for a better lifestyle, a lower cost of living, and warm weather year-round. But while the beaches and street food are easy to navigate, financial planning as an Australian expat in Thailand can be anything but simple.
As a UK expat in Thailand, I completely understand the draw it has on people. I’ve lived in the region for 10 years and recently purchased a place here. Having spoken to a lot of Australians and knowing the challenges they face when it comes to financial planning, I wanted to write a blog to help understand what’s in your control.
Whether you’re planning your retirement, building offshore wealth, or protecting your family’s future, you need to understand how your Australian Superannuation works, how offshore structures fit in with the ATO, and how Thailand’s evolving tax rules could impact your decisions.
Let’s break down what you need to know as we move through 2025.

What Should You Do with Your Superannuation?
For most Australians, Superannuation remains the backbone of retirement planning. Living in Thailand doesn’t change that — your Super stays in Australia, and you can’t move it offshore. But you can manage how it’s invested.
You should review your Super regularly to make sure it’s properly allocated for your risk tolerance and long-term plans. If you’re under 65, keeping it invested in a mix of growth and income assets often makes sense. Many expats forget that a well-managed Super can outperform other structures because of its concessional tax treatment.
Remember, once you reach preservation age, you can draw down your Super and — if structured carefully — bring funds into Thailand under the right tax window (more on that shortly).
How Do Offshore Bonds Work with the ATO?
Some Australian expats look at offshore investment bonds as a tax deferral tool. These are single-premium life policies held offshore that wrap your investments in an insurance structure.
When used correctly — that is, when you only withdraw at or below the base cost (the amount you originally invested) — any growth can be deferred for tax until you bring the gains back. However, this is a grey area with the ATO and must be done precisely.
It’s crucial to understand that these are usually sold for high commissions. If you’re considering an offshore bond, make sure you have:
- At least AUD 500,000 to invest,
- A minimum 10-year investment horizon,
- And no need for liquidity in the short term.
- Used without commission, it should cost 0.2% (or less) plus an admin fee of $500-$650 a year.
When used well, offshore bonds can help manage tax and succession planning. When used poorly, they can lock up your funds with high fees and exit penalties. Always get independent advice and ask for a clear breakdown of the costs.

Thailand’s Offshore Tax Advantages and the New 2025 Rule
One reason Australians enjoy living in Thailand is its favourable treatment of foreign-sourced income. In 2024, Thailand introduced a rule that any foreign income remitted to Thailand is taxable, regardless of when it was earned.
However, in 2025, they have proposed a significant amendment: under this draft rule, foreign income brought into Thailand in the same year it’s earned — or the following year — would not be subject to Thai tax.
In practice, this means good planning around when you bring money into the country can save you substantial tax. Many expats hold offshore accounts and only remit funds under the favourable window.

Estate Planning for Australians with a Thai Spouse
If you have a Thai wife or family, estate planning is critical. Thailand does not have an inheritance tax for most situations, but the process can be complicated if assets aren’t structured correctly. Personally, this is something which I have been thinking about how I can maximise and begin to plan for. Having recently purchased a place, we were mindful to make sure the property was in both names and that any accounts created were set up correctly.
A common approach is to:
- Keep offshore investments in your name or a trust.
- Hold Thai property in a way that your spouse can inherit easily.
- Use an offshore account or trust to pass assets to your family smoothly.
Without a clear plan, your Thai spouse may face delays, local legal challenges, or frozen accounts. Using a well-drafted Will in both Australia and Thailand (and sometimes a trust) ensures your family won’t be left sorting out a financial mess.
Setting Up Offshore Accounts: Your Practical Options
Many Australian expats in Thailand maintain offshore accounts for flexibility, asset protection, and tax planning. Some popular choices include:
Saxo Bank — A Danish investment bank known for its multi-currency brokerage accounts, global market access, and strong digital tools.
Swissquote — A Swiss platform that provides robust private banking features with access to global equities, ETFs, and managed portfolios.
Adviser-Led Platforms like Ardan International or Morningstar Wealth Platform — These offer investment accounts that can be held under trust structures for better estate planning. They also allow your adviser to manage rebalancing, reporting, and consolidated statements.
These platforms often allow you to hold multiple currencies, making it easy to manage AUD, USD, EUR, and THB from one place.
The Bottom Line
If you’re an Australian expat in Thailand, your financial plan needs to cross two tax systems, manage currency risk, and protect your wealth for the long term.
- Review your Super – Keep it working efficiently in Australia.
- Use offshore bonds only when appropriate – Large sums, long time frames, and base cost rules matter.
- Time your remittances – Take advantage of Thailand’s new 2025 tax window.
- Get your estate plan right – Especially if you have a Thai wife or kids.
- Choose offshore platforms wisely – Go for transparent, well-regulated providers, not commission-heavy offshore sales pitches.
With proper planning, you can enjoy the best of Thailand – the lifestyle, the cost of living, and the beaches – without sacrificing your financial future.
Australian expats often deal with currency exchange risks, tax obligations in both countries, and limited access to Australian superannuation. Careful planning helps avoid double taxation and ensures retirement savings remain on track.
Yes. Expats can usually keep contributing to Australian superannuation funds, but eligibility depends on income sources and residency status. It’s important to check with the ATO and consider whether international pension structures or offshore platforms may offer more flexibility
The Australia–Thailand Double Tax Agreement (DTA) helps prevent double taxation, but expats should structure income and investments carefully. Using offshore accounts, diversified portfolios, and professional tax advice can reduce liabilities and improve long-term wealth management.
