Buying a House With Bitcoin: The Capital Gains Trap in 7 Countries

Sam bought 5 BTC at $8,000 in 2017 and wants to pay 2 BTC directly for a $500,000 house. He thinks it's just a purchase. The taxman sees a $484,000 gain. Here's how the US, UK, Germany, Canada, Australia, Japan and India tax a crypto-to-property deal — and the one country where old crypto actually buys a house tax-free.

Image: Illustrative purposes. Tax rules cited from IRS Pub 544 and IRC §1031, HMRC Cryptoassets manual, BMF letter of 10 May 2022, CRA Folio S1-F5-C1, ATO ITAA 1997, NTA Income Tax Act, Indian Income Tax Act §115BBH.

Sam bought 5 BTC in 2017 at $8,000 each. Total cost: $40,000. By 2026 that position is worth $1.25 million at $250k per coin. He's found a house for $500,000 and the seller will take 2 BTC directly. Sam figures it's a purchase — bitcoin instead of dollars. No sale, no tax.

Right?

Wrong. Sam just triggered a $484,000 capital gain. The IRS treats it as a disposal of 2 BTC (basis $16,000) for proceeds of $500,000 — the FMV of the house. The gain is $484,000. At 20% long-term plus 3.8% NIIT, that's roughly $115,000 in federal tax, before state. Sam never saw a dollar of cash, but the bill is due in real USD by April 15.

Honestly, this is the most expensive mistake crypto holders make when buying real estate. Paying with crypto is never "just paying." It's a sale of the crypto to yourself at full market value, and every country here taxes it that way. If you're new to how disposals work, start with our do-you-pay-taxes-on-crypto primer, then read on for the property mechanics.

Why a crypto property deal is two transactions, not one

Here's the core idea. When you buy a house with bitcoin, every country here treats it as two simultaneous transactions.

First, you dispose of the crypto at fair market value. That's the taxable event — capital gains in the US, UK, Germany, Canada and Australia; income tax in Japan; flat 30% in India. Proceeds are the FMV of the crypto on closing day; basis is what you originally paid.

Second, you acquire the property at that same FMV. Your property basis is that value, and transfer taxes (stamp duty, land transfer tax, registration) apply exactly as with cash — calculated on the property value, not the payment method.

Two layers. Two bills. Sam forgot the first one, which is why his $500k house will cost closer to $615k once the IRS is paid.

Germany is the standout — the only country where holding crypto over a year can make the whole gain vanish. We'll get there. But most readers are in the US or UK, so let's start there.

United States: Form 8949, the 1031 ghost, and the lost mortgage deduction

In the US, using crypto to buy property is a disposition reported on Form 8949 and Schedule D. Basis is the original cost of the coins. Proceeds are the FMV of the property received — or the FMV of the crypto if that's more reliable. A $500k house paid for with 2 BTC means $500k of proceeds.

Hold over a year and you get long-term rates: 0%, 15% or 20% by income, plus 3.8% NIIT above $200k single / $250k married. Under a year, it's short-term, taxed as ordinary income up to 37%. Sam's 2017 coins clear the bar, so 20% + 3.8% on $484k.

The big misconception: using a 1031 like-kind exchange to defer. That died in 2018. The TCJA narrowed IRC §1031 to real property only, and the IRS has confirmed crypto is personal property that doesn't qualify. More on this below — it's the myth that derails the most closings.

Property transfer taxes are state-level. California's documentary transfer tax is roughly $1.10 per $1,000. New York adds a mansion tax above $1 million plus 0.4%–1.4% transfer tax. Florida charges $0.70 per $100. Cash or BTC, same bill.

The quiet loss is the mortgage deduction. A USD mortgage gives you Schedule A interest deductibility up to $750k of acquisition debt. Pay with crypto and there's no mortgage — so no deduction, ever. For a high-income buyer on a $750k loan, that's a real annual cost. Property basis is clean though: FMV at acquisition, carried forward to reduce gain on a later sale.

United Kingdom: CGT at 18%/24% and SDLT stacked on top

HMRC treats the swap as a crypto disposal. Because you're acquiring residential property, the higher 18%/24% CGT rates apply to gains above the £3,000 annual exempt amount for 2026/27 — not the 10%/20% general rates.

The same-day rule and 30-day bed-and-breakfast rule still apply. A BTC buy on closing day matches first, then buys within 30 days after, then your pool. If you've been dollar-cost averaging, a recent buy near the closing date can accidentally change which lot is matched.

Then SDLT, at the same rates as cash: 0% to £250k, 5% to £925k, 10% to £1.5m, 12% above; plus 3% on each band for second homes. A £500k main residence = £12,500 SDLT. Payment method doesn't move it.

Your property base cost for future CGT is the market value at acquisition. Sell for £700k later and the gain is £200k. The crypto and property bases are independent.

Germany: the only place old crypto buys a house tax-free

This is the section that changes the math. Under §23 EStG, private crypto disposals are tax-free if held over 365 days. The BMF letter of 10 May 2022 confirmed this applies to all crypto, and crucially, regardless of what you buy with the proceeds.

So if Sam were German and held his 2 BTC since 2017, disposing of them for the house is completely tax-free. No capital gains, no solidarity surcharge. The house costs 2 BTC and zero income tax. No other country on this list offers that.

Held under a year, the gain is taxed at the personal rate (up to 45% + 5.5% solidarity) with a €1,000 annual Freigrenze. But for anyone past the 12-month mark, Germany turns a crypto property purchase into a tax-free event. That's the key insight of this guide, and it's why German holders with older crypto should almost never sell to cash first — spend the coins directly.

The property side isn't tax-free. Grunderwerbsteuer runs 3.5% (Bavaria) to 6.5% (Berlin, Hamburg, Saarland). Notary adds ~1.5–2%, land registration ~0.5%. No VAT on private residential. Budget €30k–€45k on a €500k house.

For the full mechanics of the one-year rule with forks, staking and lot matching, our cost basis FIFO guide covers Germany's treatment in detail.

Canada: 50% inclusion plus land transfer tax

The CRA treats the deal as a crypto disposition. Fifty percent of the gain is taxable at your marginal rate. There's no personal CGT exemption for crypto — the lifetime exemption is for small-business shares and farm property, not digital assets.

Sam in Canada: $484k gain puts $242k into taxable income. At top federal (33%) plus provincial, he could pay ~50% on that $242k — roughly $121k, similar to the US once inclusion is factored in.

Land transfer tax varies by province. Ontario: 0.5% to $55k, 1% to $250k, 1.5% to $400k, 2% to $2m, 2.5% above — plus Toronto's municipal tax. BC: 1% to $200k, 2% to $2m, 3% to $3m, 5% above. First-time buyers get exemptions in most provinces. New builds also attract GST/HST.

Your adjusted cost base on the property is FMV paid plus closing costs (land transfer tax, legal, inspections). Keep the receipts.

Australia: 50% CGT discount, no main-residence shield for crypto

Under ATO rules, disposing of crypto for property is CGT event A1. Held over 12 months, you get the 50% discount — half the gain taxed at your marginal rate. Sam's $484k gain becomes $242k assessable; at top 45% + 2% Medicare levy, about $114k.

The catch: the main-residence exemption that wipes CGT on your family home does nothing for the crypto side. It applies to the dwelling, not the asset you sold to buy it. So full CGT on the crypto; main-residence only shields the eventual house sale, and only if you live there.

Stamp duty is state-based. NSW on a $500k place: roughly $9,000 + 4.5% over $300k. Victoria ~5.5%, Queensland ~$15k + 4.5% over $350k. First-home concessions apply below thresholds. New builds attract GST (10%, reducible under the margin scheme).

Property cost base = FMV of the crypto surrendered plus stamp duty, legal fees, and other acquisition costs.

Japan: miscellaneous income up to ~55%, no relief

Japan is unforgiving. Crypto disposals are miscellaneous income (雑所得), taxed at progressive rates 5%–45% plus 10% residence tax — a combined top of ~55%. No 50% discount, no holding-period relief, no main-residence treatment, no matter how long you've held.

Sam in Japan pays tax on the full $484k gain as miscellaneous income. At the top rate, that's roughly $266k — the heaviest outcome here for a long-term holder.

The NTA requires market price at the transaction time. For a property purchase, convert the property's JPY value at the BTC spot rate on closing day, and pay tax on the difference versus your average acquisition cost.

Property taxes: registration and license tax (登録免許税) ~0.4% for transfer, real estate acquisition tax (不動産取得税) ~3% of assessed value, stamp duty (印紙税) by contract amount (~¥100k on a ¥50m property). Same as a cash buyer.

India: 30% flat, 1% TDS, no deductions

India's regime for crypto is blunt. Disposals of virtual digital assets are taxed at a flat 30% under what began as §115BBH and is now codified in the 2025 Income Tax Act. There's a 1% TDS deduction on the transaction value, and you cannot claim any deductions or set off losses from one crypto sale against another. No cost-indexation, no holding-period relief, no personal exemption beyond what the basic slab offers.

For Sam in India, the $484k gain (converted to ₹) is taxed at 30% flat — about $145k. The 1% TDS is withheld at the time of the deal and credited against that liability, so he pays the balance when he files.

The property side adds stamp duty of 5% to 8% depending on the state — 7% in Maharashtra for a ₹4 crore property, 5.5% in Karnataka, 8% in Uttar Pradesh — plus a 1% registration fee. If the property value exceeds ₹50 lakh, the buyer must also deduct 1% TDS under §194-IA on the total consideration. This applies regardless of whether the consideration is paid in rupees or crypto.

Cost basis on the property is the FMV of the crypto at the transaction date, plus stamp duty and registration. That basis will matter if Sam ever sells — though India's long-term capital gains tax on property, with indexation, is a separate calculation entirely from the crypto tax.

Seven countries at a glance

The table below stacks the crypto disposal tax, the property transfer tax, the property basis, and the mortgage-interest question side by side. The "Mortgage interest in crypto?" column sounds odd — but it matters. If you pay with crypto, you have no mortgage, so you lose whatever interest deduction your country offers. If you take a USD mortgage and HODL the crypto instead, you keep the deduction but you owe the loan in dollars.

A couple of things jump off that table. Germany's 365-day exemption makes it the clear winner for anyone holding older crypto — the entire gain on the crypto side vanishes. Japan's miscellaneous income treatment is the harshest, with no discount at all. And across every country, paying with crypto means you give up any mortgage interest deduction, because there's no mortgage. That's a real, recurring opportunity cost, not a one-time fee.

The 1031 myth and the like-kind ghost

I hear this at least once a week: "I'll just do a 1031 exchange and defer the tax." It doesn't work, and it hasn't worked since 2018.

Before the Tax Cuts and Jobs Act, §1031 like-kind exchanges were available for many types of property. The TCJA narrowed the section to real property only — land and buildings. Cryptocurrency is intangible personal property. The IRS made this explicit in Notice 2014-21 and has reaffirmed it since. So a swap of BTC for a house is not a like-kind exchange. It's a taxable sale of the BTC followed by a purchase of the house, both at FMV.

Bills have been introduced to change this. H.R. 10357, for example, has been floated in various forms to restore like-kind treatment for certain crypto-to-crypto trades. But even if that bill passed, it would not cover crypto-to-real-estate swaps — the property you're acquiring is real property, and 1031 requires both sides to be like-kind. Real estate and bitcoin are not like-kind. So even in the rosiest legislative scenario, buying a house with crypto would remain a taxable event.

The like-kind ghost also haunts crypto-to-crypto trades. If you're swapping BTC for ETH to fund a property purchase, that intermediate swap is itself a taxable disposal under current law. For the full breakdown, see our crypto-to-crypto trade tax guide — same rules, same trap.

Crypto-backed mortgage vs paying directly

There's a third option that changes the tax math entirely: take out a dollar-denominated mortgage to buy the house, and keep holding the crypto. No disposal, no capital gains tax. The house is your collateral (or you use a crypto-backed loan from a lender who holds your BTC).

The appeal is obvious. Sam could keep his 2 BTC, let them keep appreciating, and buy the house with a $500k mortgage at, say, 7%. He pays about $35k in interest per year, most of which is deductible on Schedule A up to $750k of acquisition debt. He never triggers the $484k gain, and if BTC rises, he still owns it. The crypto just sits in cold storage or with the lender.

The catch is risk. If BTC drops 50%, you owe a $500k mortgage but the collateral backing it is worth half. Crypto-backed lenders can margin-call you and liquidate your position. A plain bank mortgage doesn't have margin calls, but the lender is underwriting you on your USD income, not your BTC — so you need enough cash flow to qualify. Interest rates on crypto-backed loans are also typically higher than conventional mortgages.

For the full rundown on how crypto-backed loans are taxed across these same seven countries — including where the interest is deductible and where it isn't — read our crypto-backed loans tax guide. The short version: a loan against crypto is not a disposal, so it defers the gain, but you're trading tax risk for market risk.

Practical checklist before you sign

If you've decided to pay with crypto directly, here's what to get right before closing.

Lock in a contemporaneous FMV valuation. Get a written record of the spot price of the crypto at the exact date and time of the transfer. Use a reputable pricing source — CoinGecko, CoinMarketCap, or the exchange you use. Screenshot it. If the IRS or HMRC challenges the value, you want to show you priced it off a public index at the moment of the deal. The property's appraised value should match, or come close to, the FMV of the crypto transferred.

Timestamp the transaction. Record the on-chain transaction hash, the block height, and the timestamp. If the closing happens off-chain (e.g., the seller credits you on an exchange), get a dated statement from the exchange. The timestamp proves the FMV date, which is the single most important number on your tax return for this event.

Keep the on-chain record. Link the outgoing transaction to your specific lot — the original buy that created the coins you're spending. This is where FIFO, LIFO, or specific identification comes in. If you've got multiple lots and you're using specific identification, you need a written statement of which lot you're selling before the transaction, not after. Our FIFO cost basis guide walks through how lot selection works in each country, and the free calculator on this site can run the gain math for any lot you choose.

Set aside the tax in cash before closing. This is the one that breaks people. The tax is due in your local currency, not in crypto. If you spend all your crypto on the house and have no fiat left, you'll have to sell more crypto to pay the tax — which triggers another disposal, which triggers more tax. Before you close, calculate the tax bill and set aside enough fiat (or set aside an equivalent amount of crypto earmarked for tax) to cover it. Don't close unless you can pay the tax without selling more crypto.

Honestly, that last point is the whole game. I've seen people close on a house with crypto in March and be scrambling to sell more BTC in April to cover the tax bill, locking in another gain in the process. Plan the tax cash before you sign, not after.

Bottom line

Paying for real estate with bitcoin is a taxable disposal of the crypto in every country on this list. The gain is measured at fair market value on closing day, and it's taxed under your country's normal crypto-disposal rules — capital gains in five of them, income tax in Japan, flat 30% in India. The property transfer taxes apply exactly as they would for a cash buyer, and your property basis is the FMV you paid.

Germany is the standout exception: hold the crypto for more than 365 days and the gain on the crypto side is tax-free, making a house purchase genuinely tax-advantaged. If you're a German holder with crypto older than a year, spending it directly on property is almost always better than selling to cash first.

For everyone else, the decision comes down to a trade-off. Paying directly is simple and avoids seller-side friction, but it crystallises the full gain today and forgoes any mortgage interest deduction. Taking a USD mortgage and holding the crypto avoids the disposal but adds interest cost and market risk. There is no free lunch — but knowing which lunch you're ordering is the difference between a $500k house and a $615k one.

Rates, thresholds, and exemptions change — verify with a local tax authority or qualified professional before any significant transaction.
