The cost of owning a US share from India is the money held at the door

The collection is on the rupee amount the bank converts, not on the dollars received

The tax collected at source is calculated on the rupee value of the remittance, not on the foreign currency amount that finally lands abroad. The bank applies the collection rate to the gross rupees a customer pays, which includes the bank's own conversion margin and any other charges. This means the amount frozen is slightly larger than a fifth of the visible exchange rate times the dollars sent.

Because the conversion margin is not published, a reader cannot reconstruct the exact collection base from the exchange rate alone. The bank's counter starts with the total debit from the account, and the collection is a share of that total. Two banks may debit different rupee amounts for the same dollar transfer, and the collection will differ accordingly.

This matters when a reader compares remittance costs across banks or plans a large transfer. The frozen amount is not a fixed sum per dollar but a fraction of whatever the bank decides to charge in rupees. The collection mechanism therefore amplifies any difference in conversion margins, making the most expensive bank also the one that freezes the most money.

A remittance that is reversed after collection still leaves the money frozen

If a transfer fails or is reversed after the bank has collected tax at source, the collected amount does not automatically come back to the sender's account. The bank has already deposited the collection with the government, and the reversal only affects the net amount sent. The frozen sum remains tied to the sender's tax records.

This creates a surprising outcome: a reader can have money frozen for a transfer that never completed. The only way to recover it is through the income tax return process, where the collected amount can be claimed as a credit. Until that return is filed and processed, the money stays with the government even though the underlying remittance failed.

The reversal also does not reset the sender's cumulative total for the financial year. The full amount of the attempted transfer is counted toward the threshold, even if the money eventually came back. A reader who tries again with the same funds may cross the threshold on the second attempt, leading to a larger collection than expected.

The threshold is consumed by all outward remittances, not only those for buying shares

The yearly exemption applies to the total of all outward remittances made by an individual, across every purpose allowed under the scheme. Money sent for education, travel, medical treatment, gifts, or any other permitted use counts toward the same threshold as money sent to buy US shares. The collection does not care what the money is for.

This means a reader who has already sent money abroad for a family expense will have less of the threshold left when it comes time to fund an investment. The bank's counter adds up every transfer, and once the total crosses the exempt amount, the collection begins on the remainder. The share purchase may trigger collection even if it is the first investment remittance of the year.

The cumulative nature of the threshold also means that small transfers early in the year can quietly eat into the exemption. A reader may plan a large investment transfer later, only to find that earlier remittances for other purposes have already used up the nil-rate band. The collection on the investment transfer is then higher than expected, and the frozen amount larger.

The bank's collection is a separate event from the filing that eventually releases the money

The bank collects the tax at source at the moment of remittance, but the credit for that collection is claimed only when the sender files an income tax return. There is no direct link between the two events in the bank's systems. The bank does not know whether the sender will file a return, claim the credit, or have enough tax liability to absorb it.

The gap between collection and filing is not fixed; it depends on when in the financial year the remittance is made and when the sender chooses to file. A transfer made in April may wait nearly a year before the credit can be claimed, while a transfer made in March may be claimed within weeks. The length of the wait is determined by the calendar, not by the bank or the tax department.

The credit itself is not a refund; it is applied against the sender's total tax liability for the year. If the sender has no tax liability, the collected amount becomes a refund only after the return is processed. The return must be filed correctly, and the collection must be reflected in the sender's tax records, which the bank reports to the government.

The collected amount can exceed the tax liability, turning the wait into a forced loan

The collection at source is not tailored to the sender's actual income tax situation. A reader who remits a large amount above the threshold may have far more collected than they owe in income tax for the year. The excess does not come back automatically; it is returned only as a refund after the return is filed and processed.

For a reader with modest taxable income, a single large remittance can freeze an amount that is a significant multiple of their annual tax. The money sits with the government for months, even though the sender will eventually get it all back. This is the core of the 'money held at the door' problem: the collection is not a tax but a compulsory interest-free deposit.

The larger the remittance, the more likely the collection exceeds any plausible tax liability. A reader sending the maximum allowed under the scheme in one year will almost certainly have collected an amount far greater than their income tax, unless they have an exceptionally high income. The wait for the refund then becomes the single largest cost of the remittance, measured in lost time and lost use of the money.

The threshold is not adjusted for inflation, so the frozen share of a fixed remittance grows over time

The exemption limit is a fixed number in the rules, and it does not change from year to year unless the law is amended. Meanwhile, prices and incomes rise, and the same remittance in real terms becomes a larger fraction of the threshold. A reader who sends the same dollar amount every year will find that more of it is subject to collection as the years pass.

Because the threshold is not indexed, the effective burden of the collection increases even when the rupee amount sent is unchanged. Inflation erodes the value of the exemption, so the point at which collection begins arrives earlier in the year for a reader with regular remittances. The frozen amount grows as a share of the total sent, even if the total in rupees is constant.

This effect is silent and cumulative. A reader may not notice it from one year to the next, but over a decade the difference is substantial. The same investment plan that once fit entirely within the nil-rate band can gradually cross into collectible territory, simply because the threshold stayed still while everything else moved.

The collection is taken even when the remittance is funded by borrowed money

If a reader borrows rupees to make an overseas remittance, the bank still collects tax at source on the amount sent. The collection is not waived because the funds are not the sender's own savings. A loan-financed remittance therefore has two costs: the interest on the loan and the frozen collection amount that sits with the government.

This can create a dangerous situation for a reader who borrows to invest abroad. The frozen amount reduces the capital actually deployed in the investment, while the interest on the full loan amount continues to accrue. The reader is paying interest on money they cannot use, and the investment must earn enough to cover both the interest and the opportunity cost of the frozen collection.

The bank that gives the loan and the bank that sends the remittance may be different, and neither is required to warn the reader about this interaction. The loan agreement does not mention the collection, and the remittance bank does not know the source of the funds. The reader is left to discover the double cost only after the money has left.
