Buying physical gold overseas: US, Canada, Australia and New Zealand channels, premiums and taxes compared

At this moment London spot gold is 4,120.51 USD/oz, with a bid of 4,120.18 and an ask of 4,120.83, a spread of 0.658 USD. Per gram that is 132.48 USD, and the metal value of a 100 g bar is 13,248 USD.

But the quote you see over the counter will not be 13,248. A specialist dealer in New York wants around 13,700; a bank bar in Toronto 13,850; the Perth Mint with shipping about 13,600; a vault pickup in Singapore maybe only 13,500. Same moment, same purity, same 100 g — a spread of over 300 USD.

That 300 USD is not price movement, it is channel cost. And in physical gold, the great majority of people lose money not because they read the direction wrong but because they never costed out that channel expense from start to finish. This article works through four things properly: how the premium is formed, how five categories of channel differ, how tax works in four countries, and what you actually lose on a buy-and-sell round trip.

1. The conclusion first: the premium is the real cost of physical gold

Physical gold has two prices. One is the spot price you see on a trading screen, the number like 4,120.51; the other is the retail price, which is spot plus a premium. The premium covers refining, transport, insurance, the cost of capital tied up in inventory and the dealer's margin.

On the way out there is a second haircut: the buyback discount. A dealer does not buy back at the retail price, or even at spot, but at spot less a discount — because they need a margin and face refining costs too. So on a buy and a sell you pay twice.

That table decides one thing: the larger the specification, the lower the unit cost. Casting a 1 kg bar and casting a 1 oz bar take roughly the same process, but the metal it is spread over differs by a factor of 32. So a small bar is not "the low-threshold choice", it is "the most expensive choice".

There is another point that sales patter tends to bury: coin premiums look only two or three points above bars, but coins suffer a harsher liquidity discount — small towns and small dealers often only buy back coins issued by their own country, and treat foreign coins as scrap at melt value. You buy a collectible and sell raw material, and the spread in between disappears.

2. Five kinds of channel, with completely different cost structures

Roughly five categories of place sell physical gold overseas. The distinction is not "good" versus "bad" but "expensive but convenient" versus "cheap but fiddly".

Why banks are often the more expensive option

Many people assume a bank is cheapest; in practice it is frequently the opposite. Banks sell "brand + convenience + a buyback promise", and all three are charged for. Bank bar specifications usually come in three tiers — 1 oz, 100 g, 1 kg — with no ability to buy in between. More importantly, a bank's buyback often only recognises its own bars with the original invoice; lose the invoice and the buyback price drops straight to melt value.

The specialist dealers' advantage is transparency: the page shows the spot + premium breakdown live, so you can see exactly what you are being charged. The drawback is logistics — shipping bars across borders requires declaration, many dealers only deliver domestically, and international orders require a wire with the transport risk left with you.

The Costco phenomenon deserves its own paragraph

Warehouse clubs in North America selling 1 oz bars has changed a lot of buying habits since 2023. Premiums are often squeezed to 2%–4%, below most specialist dealers, and you can earn card cashback. But there are three hard limits: purchase caps, stock-outs, and no buyback. Getting one is luck; when you sell, you still have to find a dealer. Treat it as a low-cost entry ticket, not as a complete gold plan.

3. United States: state sales tax is the biggest variable

US taxation of physical gold has two layers, federal and state, and the two work on completely different logic.

State sales tax: exempt states and threshold states

Most states exempt investment-grade bullion from sales tax, but the definitions and thresholds differ. New York exempts precious metal bars above 1,000 USD per transaction, California's threshold is 1,500 USD, while Texas, Arizona and Utah exempt essentially in full. Conversely, in states that still tax, the rate can reach 6%–9.5% — which alone eats twice your premium.

So for buying bars inside the US, the delivery address affects cost more than the choice of dealer. The same 1 oz bar costs 4,285 USD shipped to an exempt state and 4,671 USD shipped to a 9% state — a 386 USD difference. That is not a money-saving trick, it is a fixed cost you must build into the plan.

Federal capital gains: the 28% collectibles rate

Physical gold held more than a year is a "collectible" in the US, taxed at a long-term capital gains rate of up to 28% rather than the 0%–20% for ordinary long-term gains. Held under a year it is ordinary income, up to 37% for high earners.

This rule is frequently overlooked because dealers do not volunteer it. And for some products (1 oz American Eagle coins, bars of 0.995+ purity and similar) above 1,000 USD per transaction the dealer must file a 1099-B with the IRS — meaning the trade leaves a record, and the assumption that "if I don't report it they can't find it" does not hold.

Cash reporting: the 10,000 USD line

Buying gold with cash (including traveller's cheques and bank drafts) above 10,000 USD in a single transaction or within 24 hours requires the dealer to file Form 8300. Deliberately splitting into several 9,500 USD payments is called structuring, is itself a federal offence, and is far more serious than the tax owed. Bank transfers, wires and credit cards are not subject to this rule.

4. Canada: GST/HST exempt, and only half the gain is taxed

Canada's rules are relatively friendly to physical gold investors on two key points.

First, investment-grade bullion is exempt from GST/HST. Under Schedule VI of the Excise Tax Act, bars, ingots and sheets of 99.5%+ purity, plus specified coins such as the Canadian Maple Leaf, are zero-rated supplies. That means buying a 100 g bar in Toronto costs no extra 13% HST — against the 9% sales tax charged in some US states, a real 13-point gap.

Second, only 50% of a capital gain is included in taxable income. Make C$10,000 on a bar and only C$5,000 goes into that year's income at your marginal rate. Compared with the flat 28% US collectibles rate, the Canadian treatment is better for middle and high earners and can actually be worse for low earners, because of the marginal-rate stacking.

On channels: Kitco in Montreal is a long-established specialist with transparent quotes; Canadian PMX and Silver Gold Bull support online ordering and in-store pickup; some TD and Scotiabank branches sell 1 oz Maple Leaf coins, usually at premiums 2–3 points above specialists. The Maple Leaf's other advantage is the Royal Canadian Mint's 99.99% purity and anti-counterfeiting technology (radial lines), which gives it strong domestic buyback acceptance.

5. Australia: GST-free, but CGT is unavoidable

Australia exempts investment-grade gold (99.5%+ purity) from GST, a rule that has existed since the tax was introduced in 2000. So Perth Mint bar pricing is usually just "spot + premium", with no 10% tax on top.

Capital gains tax is a separate calculation. Individuals holding an asset for more than 12 months get a 50% CGT discount; under 12 months it is fully included. There is a common misconception here: some people believe "bars are a personal use asset, so they are exempt" — they are not. The A$10,000 personal use asset exemption applies to consumer items only, and investment bullion is explicitly a CGT asset.

On channels, the Perth Mint is Australia's most unusual institution: it is both a mint and runs a vaulting business (Depository), and you can buy "unallocated" gold — essentially a claim on the mint — with a trading fee of about 1% and custody of 0.5%–1% a year, and no transport or insurance issues until you take delivery. You can request physical metal later and convert to a bar with a specified serial number. ABC Bullion and Ainslie are the other two mainstream specialists, usually about 0.5 points cheaper than the mint on premium.

6. Singapore: Asia's most tax-efficient landing point

If you are in Asia, Singapore's tax structure looks almost purpose-built: investment-grade precious metals are GST exempt (since October 2012), there is no capital gains tax and no inheritance tax. Buy, hold and sell all generate no tax liability, leaving only channel premium and storage.

There are three tiers of channel. UOB sells bars from 1 g to 1 kg and also offers a Gold Savings Account — book-entry gold with a bid-ask of about 0.5%–1% and no delivery; taking delivery requires a minimum weight and a fabrication fee. BullionStar is the most transparent local specialist, showing spot and premium live on the site, and supports in-store pickup plus bonded vault storage (The Safe House). Silver Bullion follows a "vault plus lending" model, suited to larger amounts.

Singapore has one further technical advantage: vaults inside the Freeport can defer import-stage taxes, which gives non-residents more flexibility in moving money. But mind the AML rules — a single cash transaction above S$20,000 must be reported, and banks are fairly strict on source of funds when opening accounts, so have payslips, tax notices and asset sale contracts ready.

7. The UK and Hong Kong: two tax exemptions worth knowing

UK investment-grade gold (bars and sheets) is VAT exempt, a policy in place since 2000 intended to keep London the global gold trading centre. More unusual is legal-tender coinage: Britannia and Sovereign coins are legal tender and are exempt from capital gains tax on sale. That gives UK coins a persistent 3%–5% "tax premium" among local investors, and it also means their purchase premium is higher.

Hong Kong has no VAT and no capital gains tax, so bars carry only the channel premium, usually 1%–3%, the lowest tier among major markets. Members of the Chinese Gold and Silver Exchange Society (CGSE) are the main local counterparties; when choosing, check whether they are a CGSE member, whether they have a physical shop, and whether the buyback terms are written on the receipt. Bank deposit boxes cost HK$1,000–3,000 a year and are the most common way to store physical gold in Hong Kong.

Hong Kong's unit system is not the mainland's: a "tael" at a Hong Kong gold shop is 37.429 g, while the mainland market tael is 50 g, so a direct price comparison is off by 25%. How commission and fabrication are added, and how the 50 g duty-free allowance works on the way back, are costed separately here: Buying gold in Hong Kong: shops, gold grains and that 37.429 g.

8. A complete worked example: real round-trip P&L for three specifications

Put every cost into one table, calculated at today's 4,120.51 USD/oz:

The last row is what matters most. A 1 oz bar needs gold to rise 7.18% before you break even; a 1 kg bar needs only 3.55%. If gold rises 5% in a year, the 1 oz buyer is still down while the 1 kg buyer is up 1.4%. Same market, different specification, one loses and one wins.

So "I'll buy a little to try it" is unusually expensive in physical gold. Either save up for a larger specification, or do not use physical metal for small allocations at all — an ETF or a CFD is far more efficient.

9. Storage: from a drawer to a vault, a 20-fold cost difference

Weigh what an annual fee does: at 0.5% a year you lose about 18% of purchasing power over 40 years; at 1% you lose 33%. That is why "physical gold is for passing to the next generation" is only half true — if storage costs 1% a year, in thirty years what you pass on is not gold but gold minus thirty percent.

One more detail on home safes: most household policies carry a separate sub-limit for precious metals (commonly 1,000–2,500 USD), so assuming "everything in the house is covered" is wrong; you need a separate valuable items rider.

10. Compliance red lines: do not go near these

This section is about rules, not suggestions. For overseas Chinese buying gold, the problems almost never come from tax — they come from the money path.

1. An FX purchase quota is not a gold purchase quota

Mainland individuals have an annual facilitated FX purchase quota of 50,000 USD, restricted to current-account purposes such as travel, study and medical treatment, and explicitly not permitted for capital-account uses such as overseas property or securities investment. Buying FX as "travel" and then wiring it abroad to buy bars is a false purpose declaration; the bank may refuse the payment, claw it back and record it as an FX violation.

2. Split remittances are an explicit red line

Rounding up quotas from relatives and friends, breaking one large sum into several 49,000 USD transfers, all to the same overseas account — the FX regulator has explicit detection rules for this "ant moving" pattern (multiple people, short window, amounts close to the quota, concentrated recipients). Once on the watch list you lose the facilitated quota for that year and the next, and it goes into the credit record. Serious cases are handled as evasion of exchange control or illegal FX trading.

3. AML: same name, a paper trail, an explainable source

Compliance teams at overseas banks and dealers look at three things only: whether the account is in the same name, whether the money path is traceable, and whether the source can be explained with documents. Third-party payment, underground banks and converting from crypto of unknown origin all trigger suspicious transaction reports (STRs), and the result is a frozen account and a lengthy review. The best money to buy gold with is salary, dividends or property sale proceeds — funds with a complete paper trail.

4. Carrying it in: 50 g is the declaration line

Inbound travellers into China carrying gold, silver or articles made from them above 50 g must declare in writing to customs; anything beyond a reasonable quantity for personal use is cleared as goods and may be taxed. Spreading it across travelling companions or concealing it is evasion of customs supervision. This is not a question of whether you may bring it, but of whether you must declare it.

5. Automatic exchange of offshore account data

CRS obliges financial institutions to exchange account information automatically with your country of tax residence. US citizens and green card holders have FBAR (aggregate foreign accounts above 10,000 USD) and Form 8938; Canadian residents must file T1135 for specified foreign property above C$100,000. Not declaring does not mean it cannot be found, and late-disclosure penalties usually exceed the tax itself.

11. The five most common mistakes

Mistake one: looking only at the gold price, never at the premium

You see 4,120 on the screen, walk into a shop and are quoted 4,400, and feel cheated. In fact 280 of that 4,400 is premium, and that is normal for the industry. What you should actually do is compare three shops: calculate (retail ÷ spot − 1) and switch if it exceeds 5% (1 oz) or 3% (100 g).

Mistake two: treating jewellery as an investment

Jewellery carries 15%–30% fabrication cost and is bought back at 2%–5% below melt. A 20 g chain bought 25% above metal value and sold 3% below it loses close to 28% on the round trip. Jewellery is consumption, not allocation.

Mistake three: buying without confirming the buyback route

Many online dealers only buy back their own product with the original packaging and invoice. Buying is easy; selling, you discover nobody local will take it and it has to be posted back to the original seller, shipping and insurance at your cost, three weeks of waiting. Ask before you buy: do you buy back, at what discount, and what documents do you need?

Mistake four: buying physical metal with money you will need

Turning physical gold into cash takes 3–10 business days (shipping, assay, payment), and if you are in a hurry you sell at a discount to a pawnbroker. Emergency funds do not belong in physical gold. It is the same principle as "don't trade with your living expenses" in leveraged trading.

Mistake five: ignoring insurance and documents

A bar without an invoice is treated as of unknown origin at buyback and discounted further; uninsured physical gold pays nothing if it is stolen. The first thing to do after buying is photograph the serial number, scan the invoice and store it in the cloud; the second is to add it to your insurance policy.

12. When to use XAUUSD instead of physical gold

Put the cost structures of the three routes side by side and the difference is obvious:

The conclusion is clear: if the holding period is over five years and you genuinely fear extreme financial-system risk, buy physical bars; if you just want to track the gold price and adjust weights as you go, use an ETF; if you want a directional view over months or a hedge against other holdings, use XAUUSD.

Using XAUUSD for long-term preservation is a mismatch — overnight financing takes 3%–5% a year, several times the storage cost of physical gold. Conversely, using physical gold for short-term trading is also a mismatch: 5% of friction cannot be earned back on a short horizon.

If you want to judge whether the current level is a reasonable entry, start with the five indicators that matter; to convert grams and ounces use the gram-ounce converter; to cost different specifications use the gold calculator; to compare real exposure under leverage use the margin calculator; and to work out round-trip P&L use the profit calculator.

13. Summary: five sentences to take away

1. The real cost of physical gold is premium plus buyback discount: 5.5%–8% for 1 oz, 5%–6% for 100 g, 2.5%–4% for 1 kg. The bigger the specification, the cheaper it gets.
2. A 1 oz bar needs a 7.18% rise to break even; a 1 kg bar needs only 3.55%. Small-size physical buying is the least efficient way to allocate.
3. Tax differences matter more than channel differences: the US depends on the state, Canada exempts GST, Australia exempts GST but keeps CGT, Singapore exempts all three, and UK coins are CGT exempt.
4. Storage slowly eats returns: a 1% annual fee consumes 33% of purchasing power over 40 years, so do not treat "passing it to the next generation" as free.
5. The compliance red lines are on the money path: the purpose of FX purchases, split remittances, same-name deposits and withdrawals, and the 50 g declaration line. Breaching any one of them is no longer a money problem.

The gold price changes daily, but the premium structure, the tax framework and the compliance boundary have not changed in a decade. Get those straight first, then decide whether to buy, how much, and where.

Frequently asked questions

What is the minimum it costs to buy a bar overseas?

At today's 132.48 USD/g, the smallest specification is a 1 g or 1/10 oz bar, but those carry 8%–15% premiums and are terrible value. The smallest unit worth buying is 1 oz (about 4,120 USD) or 100 g (metal value 13,248 USD, about 13,700 paid). Below a 3,000 USD budget, an ETF makes far more sense.

How much do I actually lose buying and selling a 100 g bar?

At a 3.5% premium and a 2% buyback discount: pay 13,711, sell back for 12,983, a loss of 729 USD or 5.31% of principal. Gold must first rise to 4,351.76 USD/oz (+5.61%) to break even. On the same method a 1 kg bar loses 3.43%, with a break-even of 4,266.92.

Is it legal to order bars online from a tax-exempt US state and ship them elsewhere?

A seller not collecting sales tax does not make you exempt. Most states have a use tax provision requiring the buyer to self-assess and pay, at the same rate as sales tax (7%–9%). Deliberately using an exempt-state address and then forwarding the goods is tax evasion, and at large amounts can constitute tax fraud. The compliant approach is to keep invoices and settle the difference on your annual return.

What are the customs limits on bringing bars back to China?

Carrying more than 50 g of gold, silver or articles made from them on entry requires a written declaration, and anything beyond a reasonable personal quantity is cleared as goods and may be taxed. Spreading it across companions or concealing it evades customs supervision. Separately, the annual 50,000 USD facilitated FX purchase quota may not be used for overseas capital-account investment, and a false stated purpose is a clear violation.

Physical gold or a gold ETF for the long term?

If you hold for more than five years, the amount exceeds 50,000 USD and you genuinely worry about extreme financial risk, physical bars suit — at the cost of about 5% one-off friction plus 0.4%–1% a year in storage. If you simply want to track gold and adjust as you go, an ETF is better value: 0.15%–0.4% a year and a spread under 0.1%. A common approach is an ETF for the core and 10%–20% in physical.
