Moving from Australia to Japan: A Financial Guide for Expats

Moving from Australia to Japan is an exciting life decision. Whether you are relocating for work, business, or family reasons, Japan offers a dynamic economy, world-class infrastructure, and a rich cultural experience.

However, moving from Australia to Japan can also create a range of complex financial considerations. Tax residency, cross-border income, superannuation, investments, and estate planning all require careful structuring as part of the relocation. Without proper advice, Australian Expats can unintentionally trigger additional taxation or inefficient outcomes.

The following blog is a practical guide to help you navigate the financial implications of moving from Australia to Japan as an Expat.

Tax Residency: The Foundation of Your Financial Strategy

One of the most critical aspects of moving from Australia to Japan is determining your tax residency status, both in Australia and in Japan.

Japanese Tax Residency Rules

An individual is considered a resident taxpayer in Japan if they:

• have a ‘jusho’ (i.e. a domicile) in Japan, or

• have maintained a ‘kyosho’ (i.e. temporary place of abode) in Japan for one year or more.

Additionally, among resident taxpayers in Japan, there are two distinct classifications:

1. Non-permanent resident taxpayer: A resident taxpayer who is not a Japanese national and has lived in Japan for five years or less within the preceding ten years is classified as a non-permanent resident taxpayer.

   
   

2. Permanent resident taxpayer: If a resident taxpayer is a Japanese national, or a foreign national who has stayed in Japan for more than five years within the preceding ten years, they are classified as a permanent resident taxpayer.

   
   

When moving from Australia to Japan, your taxpayer classification will significantly affect how your income is taxed (discussed next).

How Japan Taxes Personal Income

Japan’s tax treatment differs depending on tax residency status and classification status:

• Non-resident taxpayers are taxed only on Japan-sourced income.

• Permanent resident taxpayers are taxed on their worldwide income.

• Non-permanent resident taxpayers (i.e. those who are not foreign nationals and reside in Japan for five years or less) are taxed on:

  • Japan-sourced income.

  • foreign-source income that is paid into or remitted to Japan only.

For Australians moving from Australia to Japan, this distinction is extremely important. For example, investment income or capital gains earned outside Japan may only become taxable if remitted into Japan, depending on your classification.

Strategic income planning before and after moving from Australia to Japan can materially impact your tax exposure.

Australian Tax Residency Still Matters

While Japanese tax residency rules are critical, your Australian tax status is equally important when moving from Australia to Japan.

If you remain an Australian tax resident after relocating, you may still need to declare:

• Japanese salary

• Dividends and investment income

• Capital gains on shares

If you become a non-resident for Australian tax purposes, different tax rules apply, including changes to capital gains tax treatment and withholding taxes.

The interaction between Australian and Japanese tax systems, including the Australia–Japan tax treaty, should be reviewed before moving from Australia to Japan to avoid unintended consequences.

Superannuation Planning Before and After Relocation

Superannuation remains one of your most valuable long-term assets when moving from Australia to Japan. Upon moving to Japan, your Australian super will generally remain preserved (i.e. inaccessible) until you meet a valid condition of release, as would be the case if you were in Australia.

Before moving from Australia to Japan, consider:

• Consolidating super accounts

• Reviewing your investment allocation

• Checking insurance inside super (life, TPD, income protection)

• Understanding contribution opportunities before departure

Superannuation does not disappear simply because you relocate. In fact, moving from Australia to Japan makes proactive super management even more important.

Managing Currency Risk Between AUD and JPY

Moving from Australia to Japan usually means earning income in Japanese yen (JPY) while maintaining assets or obligations in Australian dollars (AUD).

Currency fluctuations between AUD and JPY can significantly affect:

• Australian mortgage repayments

• Investment portfolio values

• Cash flow planning

• Future repatriation of funds

Without a currency strategy, exchange rate movements can undermine otherwise sound financial planning. When moving from Australia to Japan, it is wise to align currency exposure with future spending needs and consider the timing of large transfers.

Property Strategy: Retain or Dispose?

Many Australians moving from Australia to Japan need to decide whether to keep their Australian property.

Becoming a non-resident for Australian tax purposes can impact:

• Main residence capital gains tax exemption in Australia

• Withholding tax rules on sales under the FRCGW regime

• Land tax obligations

• Whether foreign resident tax rates apply

Whether moving from Australia to Japan is temporary or permanent will heavily influence your property strategy.

Investment Structuring Across Jurisdictions

When moving from Australia to Japan, your investment structure must be reviewed carefully. Certain Australian investments may not be tax-efficient once you become a non-resident. Similarly, Japanese investments may create reporting complexities if you later return to Australia.

Areas requiring review include:

• Australian ETFs and managed funds

• Direct share portfolios

• Trust structures

• Company ownership

• Japanese brokerage accounts

For Australian Expats with investment structures in Australia, you should also consider the deemed disposal rules and whether to apply this as part of your departure. Cross-border investment mistakes are common when moving from Australia to Japan, but they are avoidable with forward planning.

Estate Planning Across Australia and Japan

Estate planning becomes more complex once you hold assets in multiple jurisdictions.

When moving from Australia to Japan, key questions include:

• Is your Australian will still appropriate?

• Do you require a separate Japanese will?

• How will assets in each country be administered?

• Are there forced heirship considerations in Japan?

A coordinated estate plan ensures clarity and minimises stress for family members across borders.

Planning for a Future Return to Australia

Not everyone moving from Australia to Japan stays permanently. Many expats return after several years. Planning for that return before you leave is imperative, as it can reduce:

• Capital gains tax exposure

• Currency risk

• Superannuation inefficiencies

• Re-entry tax complications

• Complications with the repatriation of foreign pension funds

Moving from Australia to Japan should be approached as part of a long-term strategy, not a short-term relocation.

Conclusion

Moving from Australia to Japan offers a tremendous opportunity, personally, professionally, and financially. However, cross-border tax residency rules, Japanese personal income tax classifications, Australian tax obligations, superannuation, currency risk, and estate planning all intersect in complex ways.

The key to successfully moving from Australia to Japan is proactive planning. With the right advice, you can structure your finances to remain compliant, tax-efficient, and aligned with your long-term goals.
