Crypto Inheritance Tax Calculator

How to use Crypto Inheritance Tax Calculator

The Inheritance Tax Calculator estimates the tax impact of passing cryptocurrency to heirs. Enter the portfolio value, pick one of eight countries (US, UK, Germany, Japan, Australia, Canada, India, Brazil) and the heir's relationship to the decedent; the tool applies that country's exemption for the relationship, taxes the remainder at the country's rate, and shows the step-up in cost basis where one applies.

Cryptocurrency inherits a "stepped-up" cost basis equal to the fair market value at the date of death. This means unrealized gains accumulated over years are wiped out for tax purposes. The calculator quantifies this tax benefit: if you bought BTC at $5,000 and it's worth $77,000 at death, your heirs' cost basis resets to $77,000, eliminating $72,000 of taxable gains per coin.

What do the inputs mean?

Portfolio Value (USD) is the crypto you expect to pass on, at date-of-death value. Country selects the decedent's tax residence; Relationship (spouse, child or other) picks the exemption tier, which matters most in Germany (€500K / €400K / €20K) and the UK (spouses fully exempt).

Cost Basis drives the Unrealized Gain row and, where a basis reset applies (US, Germany), the Step-Up Benefit. Holding Period is context only and does not change the rate. The US exemption is $15M for 2026, made permanent by the One Big Beautiful Bill Act; the UK nil-rate band is £325,000. Thresholds are applied in each country's own currency, so convert first if you are near one.

How to interpret results correctly

The headline output is Estimated Inheritance Tax, shown beside an effective rate, that rate is tax divided by your full portfolio value, not the marginal bracket. Read it alongside Taxable Estate, which is portfolio value minus the Exemption Applied for your chosen relationship. A US child sees the $15M exemption swallow most estates to zero, while a German 'other' heir clears only €20K before progressive rates bite. The effective rate is the honest burden; the Tax Rate row is just the top bracket reached.

Net Inheritance is what the heir actually keeps, portfolio value minus Estimated Tax. Two rows reward closer reading: Step-Up Benefit (only shown for US and Germany, where basis resets to market value at death) is the embedded gain wiped out, and Unrealized Gain is portfolio value minus your Cost Basis. In no-estate-tax countries like Australia, Canada, or India the tax line reads $0, but that does not mean heirs owe nothing later when they sell. Check the crypto tax calculator for that disposal event.

What scenarios can you model?

Cross-border estate planning is the core use: pick the US scenario preset ($15M, child) and watch tax stay near zero under the 2026 exemption, then switch Country to the UK and see 40% bite everything above the £325K nil-rate band. Toggling Relationship between spouse, child, and other on Germany shows how the €500K / €400K / €20K exemption tiers swing the bill, invaluable when deciding which heir receives which slice of a multi-coin estate.

Use it to pressure-test 'no inheritance tax' jurisdictions. Australia, Canada, and India return $0 estate tax, but the notes flag deemed disposition (Canada), inherited cost basis (Australia, India), and India's 30% sale tax. Pair that with the Unrealized Gain row to size the latent liability your heir inherits. For Brazil's flat ~8% ITCMD or Japan's progressive 10–55% scale, model how a rising portfolio value pushes the estate into higher brackets before you gift or restructure.

What should you check before you act?

1. Before trusting the estimate: 1) Enter portfolio value at expected date-of-death fair market value, not today's price, crypto can swing wildly between planning and probate. 2) Pick the correct Relationship; spouse transfers are fully exempt in the UK and far cheaper in Germany. 3) Set Cost Basis accurately, since it drives both Unrealized Gain and the Step-Up Benefit. 4) Confirm the Country matches the decedent's tax residence, which is not always where the coins are held.
2. After calculating: 1) Read the country notes box, it states whether a step-up applies and where the real tax actually lands (estate vs heir, sale vs transfer). 2) Sanity-check that Exemption Applied never exceeds portfolio value; the calculator caps it, but a tiny estate should show full exemption and zero tax. 3) Remember Holding Period is informational context here, not a rate input. 4) Treat every figure as a simplified estimate and confirm with an estate attorney before acting.

What mistakes make this calculation wrong?

• The biggest mistake is assuming a $0 tax line means zero liability. Australia, Canada, and India charge no inheritance tax, but heirs inherit the decedent's Cost Basis and owe capital gains when they sell — India at a flat 30%, Canada via deemed disposition at death. The Unrealized Gain row is your warning light: a large gap between portfolio value and cost basis is deferred tax, not forgiven tax. Model the eventual sale in the tax calculator too.
• The second error is ignoring relationship class. People plug in 'other' (a friend, sibling, or unmarried partner) and are shocked by Germany's €20K exemption and 30–50% rates, or forget the UK fully exempts spouses while taxing everyone else at 40%. A third trap is entering current market price as portfolio value when the estate settles months later at a very different valuation, re-run it whenever Bitcoin moves materially, since a 30% price swing reshapes the entire bracket math.

What is a realistic range to expect?

Realistic figures by jurisdiction: the US exemption sits at $15M for 2026 (40% above it, with a step-up that can erase decades of gains), the UK nil-rate band is £325K with a flat 40% IHT, and Germany ranges 7–30% for close kin but 30–50% for distant heirs. Japan runs a ¥30M + ¥6M-per-heir basic deduction with progressive 10–55% rates. Brazil's state ITCMD typically lands around 4–8%.

Effective rate, not headline rate, is the realistic gauge. A $500K UK estate left to a child shows only £175K taxable after the £325K band, so the effective rate lands well under 40% even though the Tax Rate row reads 40%. Expect most modest estates in zero-tax countries to show 0.0% effective, but double digits arrive sooner than many assume: a UK estate left to a child crosses 10% at about £433K, a German 'other' heir at about €30K and a German child just above €1M, while a US estate needs roughly $20M.

Execution templates you can reuse

Workflow: 1) Estimate the portfolio's fair market value at the planning horizon, using the crypto converter to total holdings in USD. 2) Select the decedent's country of tax residence. 3) Set Relationship to the actual heir class. 4) Enter the aggregate Cost Basis so Unrealized Gain and Step-Up Benefit compute correctly. 5) Read Estimated Tax, effective rate, and Net Inheritance together, then re-run for each candidate heir.

Reuse this template per heir and per country you might relocate to. Compare the Net Inheritance figure across two or three residence scenarios before committing to a gifting or trust strategy. Where a step-up applies (US, Germany), weigh holding until death to reset basis versus gifting early; where it does not (UK, Japan, Australia), the heir carries your original Cost Basis, so a sale plan matters more. Always close by reading the notes box for jurisdiction-specific mechanics.

Data hygiene and model maintenance

Keep portfolio value current: crypto valuations drift fast, and an estate plan built on last year's price can over- or under-state the bill by a full tax bracket. Re-enter the figure after any material price move, and recompute the total in USD with the converter rather than trusting a stale spreadsheet. Refresh Cost Basis whenever you add to positions, since it directly drives the Unrealized Gain and Step-Up Benefit rows.

Treat the country rules as a snapshot, not gospel. The US note records that the One Big Beautiful Bill Act made the higher exemption permanent from 2026 ($15M, indexed for inflation in later years), German thresholds and rate bands shift with legislation, and Brazil's ITCMD varies by state. Date-stamp each calculation, note which exemption year you assumed, and re-verify against current statute before any irrevocable gift, trust funding, or relocation decision an estate professional will ultimately sign off on.

Final validation before capital deployment

Sanity-check the math by hand: the calculator computes Taxable Estate = portfolio value − Exemption Applied, then Estimated Tax = Taxable Estate × Tax Rate ÷ 100 (except for Japan, where it splits the taxable estate into equal shares per statutory heir and taxes each share with the NTA quick-calculation deduction), and effective rate = Estimated Tax ÷ portfolio value. Verify Net Inheritance equals portfolio value minus Estimated Tax. For a UK £500K estate to a child, that is (500,000 − 325,000) × 40% = £70K tax, an effective rate near 14%, confirm the rows reproduce this.

Cross-check the exemption logic against the country notes. If you select the US, Exemption Applied should jump to $15M (capped at portfolio value for smaller estates), driving tax to zero below that line. For zero-tax countries the Tax Rate and Estimated Tax must read 0, while Unrealized Gain still shows the latent gain heirs carry. If Step-Up Benefit appears, confirm the country is US or Germany; it equals portfolio value minus Cost Basis only where a basis reset applies.
