In plain words: the Black Money Act taxes two different things — undisclosed foreign income and undisclosed foreign assets — and they are treated differently.
Undisclosed foreign income
This is income that arose abroad (interest, dividends, gains, rent) that a resident did not offer to tax in India. It is taxed at the flat 30% in the year it relates to or is detected.
Undisclosed foreign asset
This is a foreign asset (a bank account, property, shares) held by a resident whose source is unexplained or which was not disclosed. The striking feature: an undisclosed foreign asset is taxed on its value (fair market value) — not just the income from it.
Why taxing the asset's value is so severe
Taxing the whole value of an asset at 30% — plus a penalty of up to three times the tax — can take a very large share of the asset. This is what makes the Black Money Act so much harsher than ordinary tax law.
When the asset is charged
An undisclosed foreign asset is generally brought to tax on its value in the year it comes to the authorities' notice — which can be years after it was acquired.
The disclosure overlay
Separately from tax, failing to disclose a foreign asset in your return (Schedule FA) carries its own penalty — even where the income was small or nil.
