With the United Kingdom preparing to abolish the non-domiciled (“non-dom”) tax status from April 6, 2025, many Australians are considering the tax impact of returning home. See our article Australians Living In The UK: How The New “Non-Dom Tax” Changes May Affect You.

Whether you make the decision to return home before the tax changes take place, or you remain in the UK until after the new laws impact you, when you return home it is important to manage your UK tax exit obligations.

Simple Checklist For Australians Returning From The UK

1. Confirm UK tax residency status and apply for split-year treatment (if eligible).

2. File a final UK tax return and settle any outstanding liabilities.

3. Plan capital gains tax-efficiently (consider selling non-UK assets after leaving to avoid UK CGT).

4. Transfer UK savings and close unnecessary UK bank accounts.

5. If keeping UK property, register with HMRC’s Non-Resident Landlord Scheme and  ensure that you continue to file UK tax returns as a non-resident.

6. Seek advice on Australian taxes and ensure your Australian tax return is prepared in accordance with Australian tax residence rules, including declaring worldwide income.

7. Review foreign asset disclosures and pension tax treatment with the ATO.

8. Be mindful of the 10-year UK IHT rule for former UK residents9- Use the UK-Australia Double Tax Agreement to mitigate double taxation.

The Key Differences For Australians Returning To Australia Before vs After The UK’s New Non-Dom Rules (April 6, 2025)

The timing of departure from the UK will significantly impact an Australian’s tax obligations in both the UK and Australia. The key differences arise in capital gains tax (CGT), inheritance tax (IHT), and foreign income treatment.

1. UK Capital Gains Tax (CGT) Implications On Worldwide Assets

The Key Difference for CGT purposes is that leaving before April 2025 allows Australians to sell non-UK assets CGT-free under the remittance basis. Individuals leaving after April 2025 may still owe UK CGT on global assets if they were UK residents for more than 4 years.

2. UK Inheritance Tax (IHT) Exposure

The key difference for IHT exposure is that before April 2025 a non-domiciled resident does not have their worldwide assets caught in UK IHT rules when they leave the UK. Leaving after April 2025 can expose them to UK IHT for up to 10 years if they were a UK tax resident for a decade or more.

3. UK Tax On Foreign Income And Remittances

Non-domiciled individuals who leave before April 2025 avoid retrospective taxation on foreign income and remittances. Leaving after April 2025 could mean more UK tax on past foreign income, depending on transition arrangements.

4. Remittance Of Foreign Income Into The UK

Prior to 2025 a non-domiciled resident would avoid UK taxes on foreign income if they did not bring this income into the UK.

Under the new UK tax rules all foreign income is taxable in the UK after the first four years, regardless of whether the income is brought into the UK or not. It is important to ensure that your Australian income isn’t brought into the UK prior to 6 April 2025 if you want to avoid UK taxes on that income.

After 6 April 2025 you may be exempt from paying UK taxes under the four-year exemption rule. If you are not exempt under this rule you may be able to bring previously untaxed foreign income into the UK under a reduced tax rate if a decision to designate this income for remittance into the UK is made before the end of the 2028 financial year. Foreign income earned from 6 April 2025 (other than income earned under the 4 year exemption rule) will be taxable, regardless of whether it is remitted into the UK or not.

5. UK Property And Rental Income

The rules remain similar in that UK rental income will continue to be taxable in the UK as the country of source, as well as being taxable in Australia as the country of residence. However, the CGT rules may be stricter for UK purposes for former UK residents, meaning that the key difference is that an individual returning to Australia may see better CGT outcomes if they sell their UK property before they leave. As this will depend on specific factors, it is important to obtain correct tax advice for your specific situation prior to making your move back to Australia.

 6. Australian Tax Treatment Upon Returning

Regardless of when an individual returns, Australians:

a) Will immediately become Australian tax residents and be taxed on their worldwide income for Australian tax purposes.

b) Must declare UK rental income, pension withdrawals, and foreign bank accounts.

c) May claim foreign tax credits for UK tax paid on income still sourced in the UK.

Leaving before April 2025 gives returning Australians more flexibility to clear UK tax obligations before Australian tax residency resumes.

Overview Of Tax Impact Of Australian Leaving Before Or After April 2025

Summary

Australians who leave the UK before April 6, 2025 will avoid new UK tax burdens on foreign assets, income, and IHT. Anyone staying past April 2025 or moving to the UK after this date, may face unexpected UK tax liabilities which may continue even after leaving.

These changes mark a significant departure from the UK’s previous tax regime. Understanding these changes is important when assessing a decision around how long you plan to live in the UK, and how this may impact your current tax obligations, as well as the tax impact on your estate.

Whether you are still making your decision on living in the UK, or need to understand the tax consequences of your decision, it is important to engage an international tax specialist who can provide up to date and accurate information tailored to your specific situation.

The United Kingdom is prepared to abolish the non-domiciled (“non-dom”) tax status from April 6, 2025. This is a significant reform which will mean that all UK residents, regardless of their domicile, will be taxed on their worldwide income.

Current Tax Rules In The UK For Non-Domiciled Individuals

Under the current tax rules Australians who live in the UK are taxed according to their domicile status and the nature of their income. An Australian who is not domiciled in the UK may make a claim to be taxed on foreign income on a remittance basis, meaning you are only taxed on any UK-source income and gains plus any foreign income remitted to the UK.

They are also able to return home to Australia without worrying about any ongoing impact of UK taxes for anything other than assets that remain in the UK.

How The UK Tax Rules Are Changing

There are a number of key aspects of the proposed changes which could have a significant impact on Australians in the UK. These include:

1. Abolition Of The Remittance Basis

Under the new system, individuals will be taxed on their worldwide income, similar to the way that Australian residents are taxed on their worldwide income. This means that while living in the UK you will need to include any income that you earn from Australian investments or income sources in other countries, even if you don’t bring that money into the UK.

2. Introduction Of A Four-Year Foreign Income And Gains Regime

On the positive side, new arrivals to the UK, who have not been UK tax residents in the previous ten consecutive years, will benefit from a new four-year period during which they receive 100% relief on foreign income and gains. This relief applies irrespective of whether the income is remitted to the UK. This effectively allows individuals to live in the UK for 4 years without having to worry about the consequences of bringing in their overseas income, and may make it more appealing for Australians to live in the UK on a short term basis that does not exceed this four year period. 

3. Imposing Inheritance Tax (IHT) Even After Departure From The UK

The domicile-based system for IHT will be replaced with a residence-based system. In addition, expats who return to Australia after the new rules are in place may be exposed to IHT for up to 10 years after leaving the UK. This makes estate planning more complex for any Australians living in or returning from the UK.

4. Capital Gains (CGT) On Worldwide Capital Gains

Australians who previously benefited from the remittance basis will now face UK CGT on all gains from worldwide assets, even if those gains are not brought into the UK.

Transitional Rules

There are a number of transitional rules that will help ease UK residents into the new tax system.

Individuals who have previously been non-domiciled and used the remittance basis of taxation will have the option to value their foreign capital assets as of April 5, 2017. This creates a new capital base value to avoid CGT applications on the increase of value up to that date.

Current non-dom individuals will also have access to a transitional discounted tax rates on their previously unremitted foreign income and gains until the 2028 tax year.

Practical Steps To Take If You Stay In The UK After April 6, 2025

Australians who are currently non-domiciled residents of the UK, who decide to stay in the UK, should take practical steps to minimise their UK tax exposure and optimise their financial position. Key actions include:

1. Revaluing assets held outside the UK prior to April 2017 for CGT purposes.
2. Selling assets before April 2025 if advantageous.
3. Utilising transitional tax reliefs by obtaining the right advice from a tax specialist.
4. Maximising the four-year tax exemption (if eligible).
5. Reviewing investment strategies, retirement planning and estate planning strategies to factor in the new tax consequences of remaining in the UK.
6. When assessing the timing of potentially returning to Australia, consider the impact of Inheritance taxes if you live in the UK for 10 years or more.
7. Keep clear records and obtain up to date tax advice to mitigate tax consequences.

It is important to engage an international tax specialist to complete a personalised assessment for tax planning in your specific situation.

Revalue Australian (And Other Foreign) Assets

You should obtain formal or independent valuations for properties, shares, and other investments as of 6 April 2017.

The UK is offering a one-time rebasing relief, allowing individuals who previously used the remittance basis to revalue their foreign assets to April 6, 2017, for Capital Gains Tax (CGT) purposes. This means only gains accrued after April 6, 2017, will be subject to UK CGT when the asset is sold. This relief is not applicable if you were deemed to be domiciled at some point between 6 April 2017 and the introduction of the new tax laws on 6 April 2025.

Plan Asset Sales Before April 2025

If you are planning to sell Australian assets:

a) Consider if there is an overall benefit in selling these assets before April 6, 2025 to avoid UK CGT.

b) If selling after April 2025, use the rebasing relief to reduce taxable gains.

c) Review whether holding assets via a trust or corporate structure might help in specific cases. If so, it may be possible to sell individually owned assets to a corporate structure that you control prior to April 6 2025.

After April 2025, all worldwide capital gains (including on Australian assets) will be taxed in the UK unless you are living in the UK for less than 4 years.

Use Transitional Tax Discounts

Take advantage of any transitional rules where possible.

a) If receiving Australian rental income, dividends, or business profits, consider bringing forward earnings to take advantage of this discount.

b) If withdrawing funds from an Australian trust or investment portfolio, consider timing withdrawals within this period.

For tax relief that is based on timing and access to transitional rules it is important to obtain correct and up to date tax information from the relevant tax specialist.

Consider How To Utilise The Four-Year Foreign Income And Gains Exemption For New Arrivals

If you have not been a UK resident in the previous 10 years then you can utilise the new four-year foreign income exemption.

a) New and recent arrivals in the UK should utilise this period of exemption to plan and structure income sources for optimal tax outcomes.

b) Where you have control over timing of income, consider triggering capital gains or significant foreign income events within the four-year exemption period.

Notably, under the new rules the four-year exemption applies regardless of whether the funds are brought into the UK. This means that any Australians who were not UK tax residents in the previous 10 years will not be taxed on foreign income or gains for their first four years in the UK. This gives Australians a good opportunity to live in the UK on a short-term basis without being impacted by the new rules.

Review Australian Superannuation And Pension Taxation

Engage a tax specialist to complete tax planning strategies for your retirement and review any current and upcoming lump sum or pension income.

a) Obtain long term advice on tax planning strategies that take into consideration the way the new rules will impact any UK tax on lump sum withdrawals or pension income from Australian super funds.

b) If applicable, time superannuation withdrawals strategically before tax rates increase.

c) Consider the types of investment income you are currently earning from Australia. Understanding the tax consequences of these changes gives you the opportunity to assess optimising your ongoing investment and income strategies.

With the tax rules changing, it is important to understand how this could impact your long-term and immediate investment and retirement plans so you can make informed decisions about your finances.

Plan For UK Inheritance Tax (IHT) On Worldwide Assets

The UK imposes an inheritance tax (IHT). Under the new rules IHT will apply to worldwide assets.

a) Consider trusts or corporate structures to protect assets from UK IHT.

b) Review wills and estate planning to align with both UK and Australian tax laws.

c) If planning to leave the UK, remember IHT exposure may continue for 10 years after departure.

Under the new rules, individuals who have been a UK tax resident for 10+ years will be subject to IHT on worldwide assets. This includes Australian property, shares, and businesses. It is therefore important to revise your inheritance strategies if you will be a long term UK tax resident. You should also consider the impact of IHT when assessing timing for making a move back to Australia, as you may be able to avoid IHT by making an earlier move.

Maximise Double Tax Relief And Tax Credits

Talk to an international tax specialist to ensure you have appropriate, current and up to date tax planning strategies in place that consider the new rules. With the UK taxing worldwide income it will be more important to utilise double taxation relief provisions to minimise your tax exposure.

a) Keep detailed tax records to claim foreign tax credits efficiently.

b) Engage an international tax advisor to structure investments efficiently.

The UK-Australia DTA can mitigate double taxation, but relief must be claimed properly as certain income types (e.g., rental income) may still be taxable in both countries.

In Summary 

The new rules will have a significant impact on Australians living in the UK, both while they are living in the UK, and when they return home. For more about the tax implications of returning to Australia under the new rules see our article Australians Living In The UK: Returning To Australia Under The New Non-Dom UK Rules.

While the new rules may reduce the tax impact of residing in the UK for a period of less than four years, long-term residents will now be liable for UK taxes on their worldwide income. This is a significant departure from the current income remittance rules and will mean any Australian currently residing in the UK should seek tax advice regarding their worldwide assets and investments. 

The current remittance basis tax regime will be replaced by a residence based regime from 6 April 2025.

Foreign Income And Gains

Existing non domiciled individuals who have been resident in the UK for less than 4 years will be able to take advantage of the new scheme which provides for tax free foreign income and gains for up to the first four years of residence.

Longer term UK residents (greater than four years) will have to pay tax on all foreign income and gains from 6 April 2025.  However, transitional arrangements will mean that:

• For the 2025/26 tax year they will only pay UK tax on 50% of their foreign income arising in that year;
• Foreign income and gains arising before 6 April 2025 will be able to be remitted to the UK in the 2025/26 and 2026/27 tax years at a temporary 12% tax rate;
• Foreign assets will be able to be re-based to 5 April 2019 value for disposals after 6 April 2025
• Foreign income and gains arising on non-resident settlor interested trusts will not be taxed unless the income and or gains are paid to UK residents.

Overseas Workdays Relief

Non-UK domiciled individuals are currently able to claim tax relief for earnings from duties overseas for up to three years of UK residence – subject to not remitting the funds to the UK.

The Government is to consult on reforming the current regime.  However, it has been confirmed that the basic relief will remain, but the restriction on remittance will be removed.  This will be a welcome simplification for many.

Inheritance Tax

The Government will consult on changes to the inheritance tax regime in light of removing domicile and changing to a residence based regime.

However, to provide certainty, they have confirmed that the treatment of non-UK assets settled into a trust by a non-UK domiciled settlor prior to April 2025 will not change. 

Summary

It is clear that the Government’s intention is to encourage capital inflows into the UK rather than provide disincentives to do so.

However, many long term non domiciled UK residents will be significantly impacted from 6 April 2025 – although the 50% restriction on income and gains subject to tax for that year will be a welcome relief.

Less clear is the position around inheritance tax.  We would welcome clarification in this regard at the earliest opportunity.

CGT Proposals

Details of the plans to impose Capital Gains Tax on gains arising to non-UK residents on the disposal of UK residential property have been published.

The proposals are wider than anticipated and also have unexpected consequences for UK resident second home owners.

CGT will be charged on gains accruing from April 2015 to non-resident individual owners, trusts, companies and partners on disposals of residential property regardless of the value of the property.

CGT will also be levied on gains arising on the disposal of investment properties, in contrast to the Annual Tax on Enveloped Dwelling (ATED) regime introduced in April 2013.

The tax payable by non-corporate sellers will be at the normal CGT rates (18% or 28%) with the benefit of the annual CGT exemption (£11,100 for 2015/16) and, if applicable, principal private residence relief (PPR).

A surprising aspect of these proposals is that both UK and non-UK resident owners of multiple homes may, in future, be denied the ability to elect which of their homes should benefit from PPR.

Instead, only the property which is, as a matter of fact, a taxpayer’s main residence or the property that qualifies as such in accordance with a proposed new fixed rule would be eligible for relief.

The rationale behind this is a concern that, if PPR is available on the sale of a non-resident’s home, the non-resident can simply elect their UK home as their main residence (rather than their non-UK property on which no CGT is payable).

Nevertheless, the proposed extension of this change to UK residents is unexpected.

That said, the Government’s dislike of “flipping” is well known and, to this end, the final period of ownership exemption for PPR has already been reduced from 36 months to 18 months for disposals on or after 6 April 2014.

The new proposals also suggest a new method of collecting CGT.

The detail here is sketchy but the idea is that non-resident sellers would have an option either to pay the tax due themselves or have the tax collected by withholding (carried out by the solicitor acting for the purchaser).

The tax would have to be paid within 30 days of completion, this could be quite onerous for the purchaser’s solicitors and it would further complicate the conveyancing process.

The application of the new CGT charge to disposals by non-resident companies will be more convoluted. Companies paying ATED will pay the related CGT charge on all or part of the gain at the usual rate of 28%.

By contrast, all other non-resident companies will be subject to a tailored CGT charge at a rate to be confirmed.

Enveloped properties

Another unexpected announcement in the recent Budget was the immediate extension of 15% SDLT to corporate purchasers of residential properties worth more than £500,000, (previously £2million).

The scope of ATED will be similarly extended but not with immediate effect. From 1 April 2015 a new band of ATED will apply, with an annual charge of £7,000 on residential properties worth more than £1m but less than £2m.

From 1 April 2016 residential properties worth between £500,000 and £1m will be charged £3,500.

The bands will otherwise remain unchanged and the current reliefs/exemptions (including those for commercially let residential property and development and trading businesses) will continue to apply.

The ATED related CGT charge will be extended from 6 April 2015 to properties worth more than £1m and will apply to that part of the gain that accrues on or after this date; and to properties worth more than £500,000 from 6 April 2016.

The balance of the gain will be treated as at present and, where the company is non-resident and part of the gain is not ATED related, the latter may also be subject to the proposed new tailored charge from April 2015.

A Mansion Tax?

Press speculation about a mansion tax grows ever more fevered whilst actual proposals remain elusive. That said, both ATED and the new CGT proposals described in this Newsletter illustrate how soft a target property is and house price inflation will surely tempt our politicians further.

Current possibilities, whether from academics or politicians, include: a progressive property tax (on houses but with relatively low values); increasing Council Tax on dwellings worth over £2m, being the latest idea from Danny Alexander; and a far more radical land value tax which would apply to all types of land.

The debate seems likely to intensify between now and May 2015. We are monitoring developments and will publish specific briefings as soon as there is something concrete to report.

Other Budget news

• Pensions: Far reaching reforms were announced to remove the requirement to purchase an annuity from pension funds and to relax the tax charges that apply to the withdrawal of funds. Some transitional measures were introduced on 27 March but the full reform will take effect from April 2015 following consultation.
• Savings: From 1 July 2014, the ISA will become a “new ISA” (NISA) with a limit of £15,000 for 2014/15 and will be able to hold any combination of cash and shares. From the same date both the Junior ISA and child trust fund limit will also rise to £4,000. From 1 June 2014, the premium bonds subscription limit will rise to £40,000; it will rise again to £50,000 in 2015/16.
• The IHT debt rules introduced from April 2013 will be amended so that foreign currency bank accounts will be treated as if they were ‘excluded property’. Therefore a liability (whenever incurred) will be disallowed for IHT purposes if borrowed funds have been deposited in a foreign currency account in a UK bank (either directly or indirectly) in respect of deaths after the date of Royal Assent of Finance Bill 2014.
• IHT Exemptions: The Government will consult on extending the existing IHT exemption for members of the armed forces who die on active service to all emergency service personnel who die in the line of duty.
• CGS: The annual cap on the total tax deductions that can be claimed under the Cultural Gift scheme & Acceptance in Lieu (for donations of pre-eminent objects to the nation) has been increased to £40m with effect from 6 April 2014.
• Accelerated tax payments: As from Royal Assent of the Finance Act 2014 HMRC will be able to require taxpayers who have used a tax avoidance scheme to make an accelerated tax payment where it considers that there is judicial ruling which has defeated the same (or a similar) scheme.

Similarly, taxpayers will be required to pay disputed tax ‘up front’ if they have claimed a tax advantage by the use of arrangements that fail to be disclosed under DOTAS; or where HMRC invokes the GAAR.

• The Government is consulting on some potentially quite alarming proposals to allow HMRC to seize money from bank accounts from anyone who owes more than £1,000 in tax or tax credits, although this will apparently be subject to certain safeguards.
• Charity definition: HMRC is proposing to amend the definition of charity for tax purposes by introducing a new ‘purpose of establishment condition’.

This aims to prevent charities being set up to abuse charity tax reliefs and is not intended to catch genuine charitable organisations.

However one of the proposed tests would deny charitable status for tax purposes if one of the main purposes for which it was established was to secure a tax advantage.

This could potentially impact on private and corporate charitable foundations as it is arguable that one of their main purposes is to obtain a tax advantage such as Gift Aid and other reliefs on donations.

Inheritance tax news

• Revised proposals to divide the nil rate band available to trusts between all trusts created by the same settlor will be published later this year and legislation introduced in Finance Bill 2015.
• The National Audit Office is launching an investigation into the possible misuse of agricultural and business property relief from IHT, as their use has almost doubled in five years.
• The Conservative Party have indicated they would consider raising the IHT nil rate band to £1m, should they be re-elected.

FATCA’s impact on trusts

The UK and US government have reached an agreement to implement a US law, the Foreign Account Tax Compliance Act (FATCA) in the UK. FATCA was designed to combat tax evasion by US residents using foreign accounts and it requires institutions outside the US to pass information to US tax authorities. A surprising range of institutions are affected by FATCA including some private trusts.

Corporate trustees and trusts which delegate the management of investment portfolios will generally need to register with the IRS by 25 October 2014, in the latter case if more than 50% of their income derives from investments.

Alternatively they may be able to enter into an agreement with a third party (e.g. the investment manager) to register on their behalf.

Thereafter they must report any US connections annually to HMRC, who will pass the information on to the IRS.

Other trusts will not need to register but may have annual reporting requirements if they have any US beneficiaries, trustees, protectors or settlors.

All trustees should consider their status and obligations under FATCA as soon as possible. For full details please see our flyer entitled ‘FATCA: What trustees need to know.’

Public register of beneficial owners

It has been clear since last November that companies will be required to make greater disclosure of their beneficial owners, but it had been assumed that trusts would be excluded as David Cameron has argued that they should be treated differently.

However, the European Parliament has recently approved an amendment to the Fourth Money Laundering Directive, which will, if implemented, make information about the individuals behind trusts publicly available for the first time.

Each EU member state would have to keep and make available a public register listing the ultimate beneficial owners of privately owned companies, foundations and trusts. There would be provisions to protect data privacy and to ensure that only the minimum information necessary is on the register.

Whilst it is appreciated that greater transparency may help to prevent criminal activity and tax evasion, many feel that these proposals go beyond what is required to achieve this aim.

Although they do seem rather worrying, they are still at a relatively early stage: final negotiations within the EU on the Directive will not begin until later this year and then each individual Member State has to incorporate the result into domestic law before the provisions take effect.

Further, the UK government has confirmed that it will oppose the mandatory registration requirement for all trusts and will seek to negotiate a compromise.

Same Sex Marriages

Since the Marriage (Same Sex Couples) Act 2013 came into force on 13 March 2014, same sex couples are able to marry in England and Wales. Civil partners should also be able to convert their legal relationship to a same sex marriage later this year, once the mechanism to do this has been introduced.

The intention is that same sex marriages should have virtually identical tax and legal consequences and effects to opposite sex marriages.

Therefore, from 13 March 2014 all legislation using marriage terminology will be read as encompassing both same sex and opposite sex marriage. The default position for interpreting legal instruments will depend upon whether or not that instrument was in existence on 13 March 2014.

Pre-existing private legal instruments will generally be read as referring only to opposite sex marriages; and new instruments from that date will be read as encompassing both opposite and same sex marriages. The position may be reversed by inclusion of specific provisions to the contrary.

Art used in a business

The Court of Appeal has confirmed that a painting used in Castle Howard’s house opening business was a wasting asset which attracted no CGT on its disposal, upholding the Upper Tribunal decision covered in our newsletter last Spring (HMRC v The Executors of Lord Howard of Henderskelfe [2014] EWCA Civ 278).

The painting in question was not owned by the business operator, but informally permitted to be used in the business, and the Court of Appeal has confirmed that the CGT legislation does not limit the exemption to assets owned by the trader.

This is potentially a very useful decision but it may not be relevant to many cases because the CGT exemption does not apply if capital allowances have or could have been claimed on the asset. It is also possible that the law could be changed.
