Selling Inherited Gold: Why the Tax Office Already Knew

Last updated: 9 September 2026. The case discussed here is investigation example 4 in the National Tax Agency's "Status of income tax and consumption tax investigations (administrative year Reiwa 6)". It was published in anonymised form by a public body and is not taken from any individual's blog. The explanations of the payment record system and of capital gains were checked against the National Tax Agency's published materials.

Sell inherited gold bullion, move the proceeds into a relative's account, run your own balance down — and say nothing, even to your own tax accountant. The tax office knew anyway, before the audit began. Why? Because the moment you sell gold bullion for more than ¥2 million in Japan, the dealer reports your name, My Number and the amount to the tax office. This instalment of Tax Audit Files reads a published NTA case about the reporting system that makes hiding pointless — and how inherited bullion is actually taxed.

The case: "if my balance is low, they cannot tell"

CASEInherited gold bullion sold, income tax never filed

Outcome: capital gain assessed, heavy additional tax imposed

The tax office had already learned, from information on file, that the taxpayer had disposed of gold bullion. No income tax return had been filed, so an audit was opened.

Once underway, examiners confirmed that the sale proceeds had been paid into the taxpayer's bank account — and that most of the money had then left it, as cash withdrawals and transfers to relatives.

Asked to explain, the taxpayer admitted knowing that a capital gains return was required, transferring the proceeds into relatives' accounts to run the balance down in the belief that "the tax office would not be able to tell" — and concealing the sale even from the engaged tax accountant.

The gain was assessed, and these acts were treated as concealment, attracting the heavy additional tax.

Income tax (1 year): undeclared income approx. ¥13 million / back tax approx. ¥4 million (heavy additional tax applied).

The "information on file": the report was made the moment you sold

The payment record for transfers of gold bullion

Dealers who trade in gold bullion must, when buying from an individual for more than ¥2 million, file a payment record with the tax office stating the seller's address, name, My Number, the type and weight of the bullion, the amount and the date (in force since January 2012).

The timeline shows every act of hiding came too late: the report was triggered at the counter, before the money even landed. Moving funds afterwards does not erase income — it only builds the evidence of intent that the heavy additional tax requires. Transfers into relatives' names and concealment from one's own tax accountant are textbook material for a concealment finding.

How inherited bullion is actually taxed

Point	Rule
Special deduction	Capital gains enjoy a ¥500,000 annual special deduction
Long-term halving	Held over 5 years: only half the gain (after the deduction) is aggregated with other income
Inherited bullion	You inherit the deceased's acquisition cost and date — not the value at inheritance. Gold bought cheaply decades ago produces a large gain
No records	Without purchase records, deemed cost is 5% of the sale price — 95% of the price becomes taxable gain

Find the purchase documents among the estate papers before selling. And note: splitting sales into sub-¥2-million lots does not remove the filing obligation — dealers keep identity records, repeated sales are visible, and deliberate splitting itself reads as intent.

FAQ

Q. No audit notice has come yet. What can I do now?

A. File voluntarily before advance notice of an audit and the penalties fall sharply — the non-filing penalty drops to 5% in principle. Left until after an audit it runs 15–30%, and 40% if concealment is found.

Summary

The taxpayer sold inherited gold bullion, moved the proceeds into relatives' accounts and hid it from the tax accountant. Unreported income was about ¥13,000,000, additional tax about ¥4,000,000, and heavy additional tax was also imposed.
For purchases over ¥2,000,000, bullion dealers submit a payment record to the tax office listing the seller's name, My Number and the amount paid.
Moving money between accounts does not erase income. Inquiries to financial institutions during an audit reconstruct the flow, and it only becomes evidence of intent.
Gains on sale are in principle capital gains (aggregate taxation). There is a ¥500,000 annual special deduction, and if held over 5 years only half of the amount after the deduction is added to income.
Inherited gold bullion carries over the deceased's acquisition cost and acquisition date. Without purchase records, the estimated acquisition cost is 5% of the sale price, which is very unfavorable.
