An inheritance from overseas is rarely taxed twice, but it is nearly always reported twice — once in the country where the deceased lived and again in the country where the beneficiary lives. The two systems rarely line up. A German estate pays tax before the money crosses the border; the U.S. beneficiary then files an information return on the same amount. A UK grandparent's bequest passes through inheritance tax at 40% above the nil-rate band; the Australian grandchild receives it free of income tax but inherits a capital-gains base problem that only surfaces years later.
This piece works through the taxation and reporting mechanics of receiving inheritance from abroad tax in three high-tax jurisdictions — the United States, the United Kingdom, and Australia — then covers the currency-conversion timing decisions and the practical choice between a bank wire and an FX broker for moving the principal. All figures are as of 2026; a qualified cross-border adviser should verify jurisdiction-specific rules before acting.
Country of source versus country of residence
Almost every domestic inheritance regime uses one of two designs. The estate model, used by the United States and the United Kingdom, taxes the estate of the deceased before assets are distributed. Beneficiaries receive the residue tax-free at the domestic level. The inheritance model, used by Germany, France, Spain, and many other European jurisdictions, taxes each recipient individually, with rates and allowances that vary by the family relationship to the deceased.
The country of the deceased almost always taxes first. Where the deceased was domiciled and where the assets were situated between them fix the primary charge. The country of the beneficiary then decides whether to layer further tax or reporting on top. The interaction between the two is what makes cross-border inheritances complicated — not the rate itself, which is often benign or nil for the recipient.
Three questions frame every case:
- Where was the deceased tax-resident or domiciled at death?
- Where are the assets physically or legally situated (immovable property, brokerage accounts, private company shares, life policies)?
- Where is the beneficiary tax-resident when the assets pass, and when the beneficiary later disposes of them?
United States beneficiary: no income tax, but Form 3520 is unforgiving
A U.S. person who inherits from a nonresident alien or foreign estate does not pay U.S. income tax on the inheritance itself. Federal estate tax falls on the estate of the deceased, not on the beneficiary, and a foreign estate is generally outside the U.S. estate tax net for foreign-situs property. Under the One Big Beautiful Bill Act, the U.S. federal estate tax exemption sits at USD 15 million per individual (USD 30 million for a married couple) effective 2026, indexed thereafter, with rates of 18–40% above the exemption. That regime applies to the estates of U.S. citizens and domiciliaries — not, in most cases, to a foreign estate leaving foreign-situs assets to a U.S. relative.
The reporting side is where U.S. beneficiaries get caught. When aggregate gifts or bequests from a nonresident alien individual or foreign estate exceed USD 100,000 in a single tax year, the U.S. recipient must file Form 3520, Part IV. The form carries no tax, but the late-filing penalty is 5% of the unreported amount per month, capped at 25%. On a USD 500,000 unreported inheritance that reaches USD 125,000 before questions of willfulness are even considered. Our dedicated Form 3520 foreign trust and inheritance reporting guide walks through the thresholds, aggregation rules across related donors, and the substitute Form 3520-A filing when the foreign trustee will not.
Three additional U.S. traps regularly appear once the inheritance is received:
- Cost basis is stepped up to fair market value at date of death for U.S. tax purposes on inherited assets, in most cases. The step-up applies even when the deceased was foreign and the asset was foreign-situs — meaning the U.S. beneficiary can often sell inherited foreign real estate or securities with little or no U.S. capital gain, provided the valuation is properly documented in USD at the date of death.
- Foreign accounts holding the inheritance become the beneficiary's, triggering FBAR (FinCEN 114) filing when aggregate foreign account balances exceed USD 10,000 during the year, and FATCA Form 8938 at higher thresholds. See the FBAR and FATCA reporting guide for the mechanics.
- Inherited foreign pension pots, investment wrappers, and mutual funds can trip the PFIC rules or be characterised as foreign trusts — a completely separate reporting regime with 35% distribution penalties. Any inheritance that includes anything other than cash needs a U.S.-qualified adviser to classify the assets before disposal.
United Kingdom beneficiary: the nil-rate band belongs to the estate, not to you
UK inheritance tax at 40% above the £325,000 nil-rate band is charged on the estate of the deceased, not on the beneficiary. For UK-resident beneficiaries receiving from a foreign deceased who was not UK-domiciled and held no UK-situs assets, there is generally no UK inheritance tax at all. The nil-rate band belongs to the deceased's estate; it is not a personal allowance the beneficiary can shelter behind.
Since 6 April 2025, the UK's inheritance tax framework has moved from a domicile-based to a residence-based system. A person who has been UK-resident for 10 of the previous 20 tax years is a long-term resident and their worldwide estate is in scope on death. This is a change to the taxation of the deceased — but it matters to beneficiaries because a parent who has lived in the UK for a decade before dying may now bring assets in Portugal, Australia, or the U.S. into UK IHT scope that would previously have been out of it. The related UK non-dom abolition analysis walks through the transition rules and the Temporary Repatriation Facility for pre-6 April 2025 foreign income and gains.
What UK beneficiaries almost always face is not an inheritance tax charge but subsequent income tax and capital gains tax on what the inheritance earns and grows:
- Foreign rental property inherited by a UK resident begins to generate UK-taxable rental income immediately, taxed on the arising basis at the recipient's marginal rate (up to 45% in England, with credit relief under the relevant treaty for foreign tax paid abroad).
- Foreign securities and cash produce dividends taxed at 8.75–39.35% and interest taxed at up to 45%, from the date of receipt.
- Capital gains on later disposal are computed against the base cost at the date of death, converted to sterling using the exchange rate on that date. UK CGT is 18% (lower rate) or 24% (higher rate) from 30 October 2024. Residential property is taxed at 24%.
Australian beneficiary: no inheritance tax, but a live CGT clock
Australia has no federal inheritance tax, and state death duties were abolished by the late 1970s and early 1980s. An Australian resident receiving a foreign inheritance therefore pays no Australian tax on the receipt itself, whatever the source country. The Australia country profile confirms the position remains as stated in 2026.
The catch is capital gains. Where a deceased was a non-resident of Australia and passed on non-taxable Australian property to an Australian resident beneficiary, the Australian tax framework generally applies a cost base equal to the market value at date of death. Where the deceased was an Australian resident, the beneficiary in most cases inherits the deceased's original cost base — a very different figure, often decades old. When the beneficiary later sells the asset, the CGT event is calculated in Australian dollars using the exchange rate on the date of the disposal, with the 50% CGT discount available on assets held (through the deceased and the beneficiary combined) for more than 12 months.
Practical consequence: the same physical inheritance — say, a portfolio of European shares — can produce very different Australian tax outcomes depending only on whether the deceased was Australian-resident or not. Documentation of the deceased's residency status at death, the acquisition history of each asset, and the AUD valuation at date of death is essential and should be gathered while probate is still live rather than reconstructed years later.
How the three regimes line up
| Feature | United States | United Kingdom | Australia |
|---|---|---|---|
| Recipient-side inheritance tax | None (federal) | None (charge is on the estate) | None |
| Domestic estate/inheritance tax on the deceased | 18–40% above USD 15M exemption (2026) | 40% above £325,000 nil-rate band | None |
| Recipient reporting obligation | Form 3520 Part IV above USD 100,000 from a foreign individual/estate | Report subsequent income and gains via self-assessment | No specific inheritance disclosure; declare later income and CGT |
| Cost base for later disposal | Stepped up to FMV at date of death (in most cases) | FMV at date of death, converted to GBP on that date | Depends on deceased's residency at death |
| Personal income tax basis | Citizenship-based, worldwide | Residence-based, worldwide from April 2025 | Residence-based, worldwide |
Figures above are as of 2026 and jurisdiction-dependent; verify with a qualified local adviser before acting.
Currency conversion timing
Almost every tax outcome above depends on which exchange rate applies on which date. Three dates matter:
- Date of death. Fixes the cost base of the inherited asset in the beneficiary's local currency for future capital-gains calculations. Use the beneficiary's home-country central bank rate, or the tax authority's published rate, on that day. Document the source of the rate.
- Date of receipt. The date the beneficiary receives the cash or takes legal title. For Form 3520 aggregation and for reporting the amount in USD, GBP, or AUD, this is generally the correct rate. Where an inheritance is paid in tranches, each tranche is converted at its own date.
- Date of disposal. When the beneficiary later sells, the disposal proceeds are converted at the rate on the date of sale. The gain or loss is the difference between the two converted figures, not the difference in the source currency.
The gap between these dates can create foreign exchange gain or loss that has nothing to do with the underlying investment. A EUR 500,000 bequest received in January and converted to AUD in March at a stronger euro can produce an AUD gain that is taxable notwithstanding no change in the euro value of the assets. The currency exchange gains tax piece works through the recognition rules in each of the three jurisdictions.
Bank wire versus FX broker: slippage on the principal
Once the tax questions are resolved, the transfer route affects the amount the beneficiary actually receives. A high-street bank wire — SWIFT MT103 with a foreign-exchange conversion at the retail counter rate — typically embeds a spread of 2–4% against the interbank mid-rate, plus a wire fee of USD 25–50 at each end and often an intermediary bank fee of USD 15–25. On a USD 200,000 transfer, the spread alone can be USD 4,000–8,000.
A regulated FX broker or payments specialist (Wise, OFX, Currencies Direct, and similar) typically prices at 0.3–0.7% above interbank on cross-border transfers of this size, with per-transfer fees that are either zero or a small flat amount. On the same USD 200,000, the total cost is often below USD 1,500. The trade-off is operational: the broker requires a local account in the sending currency, KYC on both the source and destination, and — for inheritance funds — usually evidence of source (grant of probate, executor's letter, or foreign estate distribution statement).
Two practical points routinely reduce slippage further:
- Time the conversion, not the transfer. The beneficiary can receive the foreign-currency inheritance into a same-currency account, hold it, and convert when the rate is acceptable — separating settlement from FX. This also allows the beneficiary to fix the tax-relevant exchange rate at the moment of choice, subject to the timing rules above.
- Split large transfers. Where the inheritance materially exceeds the amount the beneficiary needs to spend or invest in the near term, transferring in tranches spreads FX risk and avoids concentration risk against a single day's rate. It also simplifies documentation where each tranche can be tied to a specific probate distribution.
The broader mechanics — routing, timing, and tax treatment of the transfer itself — are covered in the best way to transfer money abroad and sending money abroad analyses.
A practical sequence for the beneficiary
- Obtain the grant of probate (or the equivalent estate document in the source country) and a full inventory of assets in original currency and at date-of-death valuation. This is the single most important piece of documentation the beneficiary will need for the next decade.
- Confirm the residency status of the deceased at death — under the source country's rules and, if relevant, under the beneficiary's country rules. This determines which country charges primary inheritance tax and, in Australia's case, which cost-base rule applies.
- Get a written U.S. tax classification of every non-cash asset if the beneficiary is a U.S. person — foreign trusts, PFICs, and life-wrapper products need to be identified before disposal.
- Fix and document the exchange rate at the date of death and at each date of receipt, using a published tax authority or central bank source.
- Route the transfer through a regulated FX broker where the amount justifies it, holding the foreign currency in a same-currency account until conversion is deliberate.
- File the local reports: Form 3520 in the U.S. above USD 100,000; UK self-assessment for any subsequent income and gains; Australian tax return disclosing the cost base assumed for CGT purposes.
- Retain all documentation for at least six years — probate, valuations, exchange rate sources, transfer receipts, and any advice received. In the U.S., the reporting statute of limitations for Form 3520 does not begin to run until the form is filed.
