Charge of Tax under the Black Money Act, 2015

Updated 11 October 2026 · Fact-checked

Under Section 3 of the Black Money Act, 2015, tax at 30% is charged on the total undisclosed foreign income and asset of the previous year. An undisclosed foreign asset is taxed on its value in the previous year it comes to the Assessing Officer's notice. No deduction or loss set-off is allowed.

Understand Charge of Tax on Undisclosed Foreign Income and Assets

The Black Money Act, 2015 is a separate charging Act. It taxes foreign income and foreign assets that you have not disclosed in India. It extends to the whole of India and came into force on 1 July 2015.

Section 3 is the charging section. It charges every assessee, for every assessment year commencing on or after 1 April 2016, a tax at 30% of the total undisclosed foreign income and asset of the previous year.

Section 4 tells you what that total contains. It has three parts: (a) foreign-source income not disclosed in the return filed in time; (b) foreign-source income where a return was required but none was filed in time; and (c) the value of an undisclosed asset located outside India.

The timing rule is the key exam point. The proviso to Section 3(1) says an undisclosed foreign asset is charged on its value in the previous year in which it comes to the notice of the Assessing Officer. It is not charged in the year you bought it. "Value" means fair market value, including financial interest in any entity, determined in the prescribed manner.

Two more rules complete the charge. Section 5 bars deductions and set-off of losses, and gives a limited reduction for assets bought from income already taxed. Section 4(3) says income taxed under this Act does not form part of total income under the Income-tax Act, so it is not taxed twice.

Key rules to remember

Charge of tax (Section 3(1))
Tax = 30% × total undisclosed foreign income and asset
Applies for assessment years commencing on or after 1 April 2016. Tax only; penalty and interest are separate.
Total undisclosed foreign income and asset (Section 4(1))
(a) undisclosed foreign income in return + (b) foreign income where no return filed + (c) value of undisclosed foreign asset
Income is from a source located outside India. The asset must be located outside India.
Year of charge for an asset (proviso to Section 3(1))
Taxed on its value in the previous year in which it comes to the notice of the Assessing Officer
Value means fair market value, determined in the prescribed manner.
Computation rule (Section 5(1)(i))
No deduction for expenditure or allowance and no set-off of loss
Applies whether or not the item would be allowed under the Income-tax Act.
Reduction for taxed income: assets in general (Section 5(1)(ii))
Chargeable value = Value of asset − income already assessed or assessable that the asset was acquired from
Income assessed under the Income-tax Act before the year to which this Act applies, or assessable or assessed under this Act, is reduced from the value. The assessee must furnish evidence to the Assessing Officer's satisfaction. No proportion is used for assets other than immovable property.
Reduction for taxed income: immovable property (Section 5(2))
Reduction = Value of asset on the first day of the financial year of notice × (assessed or assessable foreign income ÷ total cost of asset); Chargeable value = Value − Reduction
The proportion applies only to immovable property. Evidence must satisfy the Assessing Officer.
Rounding (Section 79)
Income and asset: nearest ₹100. Amount payable or receivable: nearest ₹10
Method is as prescribed.
No double taxation (Section 4(3))
Income taxed under this Act is not part of total income under the Income-tax Act
Also, Section 4(2) excludes certain assessment variations (transfer pricing and computation provisions) from undisclosed foreign income.

How to solve Charge of Tax on Undisclosed Foreign Income and Assets questions

Use this order for any question on the charge of tax under the Black Money Act.

  1. 1Identify the item: is it foreign-source income or an asset located outside India? Financial interest in an entity counts as an asset.
  2. 2Check disclosure. For income, was it disclosed in the return filed in time, or was no required return filed? For an asset, was it undisclosed?
  3. 3Fix the year of charge. For an asset, it is the previous year in which it came to the Assessing Officer's notice, not the year of acquisition.
  4. 4Take the value: fair market value. If the asset is immovable property and a reduction is claimed, Section 5(2) uses the value on the first day of the financial year in which it came to notice.
  5. 5Allow no deductions or losses. Then apply the Section 5(1)(ii) reduction only if the assessee furnishes evidence that the asset was acquired from income already assessed or assessable to tax.
  6. 6Compute the reduction by asset type. For immovable property, use the proportion: value × taxed income ÷ total cost (Section 5(2)). For any other asset, such as a bank deposit, subtract the income assessed or assessable that funded it (Section 5(1)(ii)). Deduct the reduction from the value.
  7. 7Add the income and the net asset value, round off to the nearest ₹100 (Section 79), and apply 30%.
  8. 8State that the income is excluded from total income under the Income-tax Act (Section 4(3)) and mention that penalty and interest are charged separately.

Quickest way: Four-line shortcut

When to use it: Use it for numerical questions on an overseas asset that has come to notice.

  1. Write: Year of charge = year of notice.
  2. Reduction: for immovable property, value on the first day of the financial year of notice × (taxed portion ÷ cost). For any other asset, the taxed income that funded it, shown by evidence.
  3. Chargeable value = value − reduction; add any undisclosed foreign income with no deductions.
  4. Tax = 30% of the total. Add a one-line note on Section 4(3).

Common mistakes in Charge of Tax on Undisclosed Foreign Income and Assets

  • Taxing the asset in the year it was acquired.

    Students carry over the habit of taxing income in the year it is earned.

    Fix: Use the proviso to Section 3(1): the asset is charged on its value in the year it comes to the Assessing Officer's notice.

  • Using the cost of the asset as the base instead of its current value.

    Cost is the familiar base under the Income-tax Act.

    Fix: The charge is on fair market value. Cost appears only as the denominator in the proportion for immovable property.

  • Allowing expenses or loss set-off against undisclosed foreign income.

    Students apply ordinary computation rules.

    Fix: Section 5(1)(i) allows no deduction or set-off, whether or not allowed under the Income-tax Act.

  • Reducing an overseas immovable property by the taxed income in rupees, not proportionately.

    The reduction seems to be simple subtraction.

    Fix: For immovable property, Section 5(2) scales the reduction by value ÷ cost. In the Act's illustration of a house property, ₹20 lakh of ₹50 lakh cost gives ₹1 crore × 20/50 = ₹40 lakh.

  • Applying the Section 5(2) proportion to a bank deposit or other asset that is not immovable property.

    Students treat the house-property illustration as the rule for every asset.

    Fix: The proportion is for immovable property only. For other assets, Section 5(1)(ii) reduces the value by the income assessed or assessable, if evidence is furnished.

  • Including the same income again in total income under the Income-tax Act.

    Students forget the Acts are separate.

    Fix: Section 4(3) keeps income taxed under this Act out of total income under the Income-tax Act.

  • Applying the reduction without evidence.

    Students treat the reduction as automatic.

    Fix: The assessee must furnish evidence to the Assessing Officer's satisfaction that the asset came from income already taxed.

Worked examples

Example 1

Mr. Rajan Iyer, a resident, bought a flat abroad in 2009-10 for ₹50,00,000. Of this, ₹20,00,000 was assessed to tax in India in the total income of 2009-10 and earlier years, and he has evidence. The flat came to the Assessing Officer's notice in the financial year 2017-18. Its value on 1 April 2017, the first day of that financial year, was ₹1,00,00,000. Compute the amount chargeable and the tax under the Black Money Act. (This follows the pattern of the Act's own illustration under Section 5.)

Show the solution
  1. The asset is charged in the previous year in which it comes to notice, so the year of charge is the previous year 2017-18 (assessment year 2018-19).
  2. The flat is immovable property, so Section 5(2) applies. Value on 1 April 2017 = ₹1,00,00,000.
  3. Reduction under Section 5(2) = ₹1,00,00,000 × 20,00,000 ÷ 50,00,000 = ₹40,00,000.
  4. Chargeable value = ₹1,00,00,000 − ₹40,00,000 = ₹60,00,000. This is already a multiple of ₹100 (Section 79).
  5. Tax at 30% = ₹60,00,000 × 30% = ₹18,00,000.

Answer: Amount chargeable ₹60,00,000; tax ₹18,00,000 (before penalty and interest).

Example 2

Ms. Meera Shah, a resident, held a foreign bank deposit that came to notice in the relevant year. Its value was ₹40,00,000. She also earned foreign rental income of ₹6,00,000 (after no adjustment), with ₹1,00,000 of expenses and a ₹2,00,000 loss from another foreign source. She did not disclose this rental income in her return filed in time (or, alternatively, she filed no return although one was required), so Section 4(1)(a) or (b) applies. She cannot prove that any part of the deposit came from taxed income. Compute the tax under the Black Money Act, ignoring penalty and interest.

Show the solution
  1. The rental income is from a source outside India and was not disclosed in a return filed in time, so it falls within Section 4(1)(a) or (b). The deposit is an undisclosed asset located outside India under Section 4(1)(c).
  2. Section 5(1)(i) allows no deduction for expenses and no set-off of loss.
  3. Undisclosed foreign income = ₹6,00,000, with no deduction of ₹1,00,000 and no set-off of ₹2,00,000.
  4. No reduction is available for the deposit, as she has no evidence of taxed income.
  5. Total undisclosed foreign income and asset = ₹6,00,000 + ₹40,00,000 = ₹46,00,000.
  6. Tax at 30% = ₹46,00,000 × 30% = ₹13,80,000.
  7. The income is not included in her total income under the Income-tax Act (Section 4(3)).

Answer: Tax under the Black Money Act is ₹13,80,000.

Exam tips

  • For numerical questions, write the year-of-notice point in the first line. Examiners look for it.
  • Quote the 30% rate and "no deduction, no set-off" with Section 3 and Section 5.
  • For immovable property, show the reduction as a proportion, as in the Act's illustration. For other assets, reduce by the taxed income itself. Show each step so you earn method marks.
  • In MCQs, watch for options that tax the asset in the year of acquisition or on cost. Both are wrong.
  • End with the Section 4(3) point to show the income is not taxed twice.

Practice questions from Black Money Act, 2015

Charge of Tax on Undisclosed Foreign Income and Assets: frequently asked questions

What is the tax rate under the Black Money Act, 2015?

The rate is 30% of the total undisclosed foreign income and asset of the previous year (Section 3(1)). It applies to assessment years commencing on or after 1 April 2016.

In which year is an undisclosed foreign asset taxed?

It is taxed on its value in the previous year in which it comes to the notice of the Assessing Officer. The year of acquisition does not decide this.

How is the value of an undisclosed foreign asset determined?

Value means fair market value, including financial interest in any entity, determined in the prescribed manner. If the assessee furnishes evidence that the asset came from income already taxed, that income is reduced from the value under Section 5(1)(ii). For immovable property, Section 5(2) makes the reduction proportionate to the taxed income over the total cost.

Can I claim expenses or set off losses against undisclosed foreign income?

No. Section 5(1)(i) disallows any deduction or set-off of loss, whether or not the Income-tax Act would allow it.

Is the income taxed again under the Income-tax Act?

No. Section 4(3) says income included in the total undisclosed foreign income and asset does not form part of total income under the Income-tax Act.
