Form 15CA and 15CB for LRS: when Indian investors actually need them (and when they don't)

A software engineer in Bengaluru wanted to wire $5,000 to her Interactive Brokers account to buy S&P 500 ETFs. Her bank's relationship manager told her she needed Form 15CA and Form 15CB — the latter requiring a CA certificate that would cost ₹5,000 and take a week. She paid, filed, and made the transfer. Six months later, a colleague told her he had been making the same LRS transfers for three years with no 15CA or 15CB, and that the bank was applying a rule that did not apply to investment remittances.

Both of them were right — in a sense. But only one of them paid unnecessarily.

This article explains the actual legal framework, what the exemption says, when the forms are genuinely required, and what to do when your bank conflates its internal KYC rules with a statutory requirement.

What Form 15CA and Form 15CB actually are

Form 15CA is an online declaration that a remitter (you) files on the Income Tax Department's e-filing portal before making a foreign remittance. The purpose is to give the tax department visibility into money leaving India, so it can track whether the outflow has Indian tax implications.

Form 15CB is a certificate issued by a practising Chartered Accountant. The CA certifies the nature of the remittance, the applicable Double Tax Avoidance Agreement (DTAA) provisions if relevant, and confirms that tax has been correctly withheld (or that the remittance is not taxable in India). It is a prerequisite for filing certain parts of Form 15CA.

The bank is required to obtain Form 15CA from you before processing a foreign remittance — but only for remittances that are not specifically exempted.

The governing rule: Rule 37BB of the Income Tax Rules

The entire 15CA/15CB framework flows from Section 195(6) of the Income Tax Act and is implemented through Rule 37BB of the Income Tax Rules, 1962.

Rule 37BB breaks Form 15CA into four parts based on the nature and amount of the remittance:

Part	When it applies	15CB required?
Part A	Remittances up to ₹5 lakh (aggregate, all purposes) in a financial year	No
Part B	Remittances above ₹5 lakh, where the amount is NOT taxable in India (or covered under DTAA)	Yes — must get 15CB from CA first
Part C	Remittances above ₹5 lakh, where the amount IS taxable in India	Yes — must get 15CB from CA first
Part D	Remittances covered under the Rule 37BB(3) exempt list	Not applicable — no 15CA required at all

The last row is where most Indian retail investors who remit under LRS to buy US stocks actually land — and it is the row that most bank relationship managers forget to tell you about.

The exemption that most investors don't know about: Rule 37BB(3)

Rule 37BB(3) contains a specific list of 28 remittance types that are completely exempt from the Form 15CA requirement. No Form 15CA. No Form 15CB. No CA certificate. Nothing.

Among those 28 categories, the relevant ones for Indian investors using the Liberalised Remittance Scheme to invest in foreign equity and debt markets are:

• Purpose code S0001 — Investment in equity shares of companies abroad
• Purpose code S0003 — Investment in debt securities abroad (bonds, debt funds)

These are LRS-purpose codes used by the Reserve Bank of India to classify outward remittances. When you wire money to buy US stocks, your bank's outward remittance form will carry one of these purpose codes. Because these purpose codes are on the Rule 37BB(3) exempt list, the legal position is that you do not need Form 15CA or Form 15CB for these transfers.

This exemption was introduced as part of the 2013 amendment to Rule 37BB and has been in place continuously since. The intent is clear: investment outflows under LRS are tracked by the RBI through the purpose code system and the LRS declaration (Form A2), which already captures the nature of the remittance. Overlaying a tax department compliance form on top of an RBI-regulated channel was seen as redundant.

Why your bank may still ask for Form 15CA

If the law exempts you, why does the bank's compliance team ask for 15CA?

The answer is institutional risk aversion. The authorised dealer bank (your bank) is responsible under FEMA for ensuring the remittance is legitimate. The bank's internal compliance policy — written by its legal and risk team — often sets a more conservative threshold than what the law requires. Banks cannot afford to process a remittance that later turns out to have had a tax liability, even if the rule technically exempted it from 15CA.

In practice:

• Private sector banks with digital LRS platforms (HDFC, ICICI, Axis via their LRS portals) usually do not ask for 15CA for investment-purpose LRS remittances under the standard $250,000 annual LRS cap. The portal auto-classifies the remittance under the exempt purpose code.
• PSU banks and relationship-manager-driven processes are more likely to ask for 15CA, especially for larger amounts or first-time LRS customers.
• Some banks have internal thresholds — for example, requiring 15CA for any LRS remittance above ₹10 lakh regardless of purpose code — that are more conservative than the Rule 37BB(3) exemption.

If your bank asks for Form 15CA, you are not being lied to — the bank has a right to set its own internal compliance requirements. But you should know that the bank's request is a KYC/AML requirement, not a statutory mandate under the Income Tax Act. You have a few options:

1. File Part A (no CA needed) if your cumulative LRS remittances in the financial year are under ₹5 lakh — this satisfies the bank's checkbox with minimal effort and zero CA fees.
2. Push back or use a different channel — if you are using an investment platform (Vested, INDmoney, Groww Global), the platform aggregates remittances and handles the bank side for you; you don't file 15CA personally.
3. Work with a CA to file Part B or Part C if the bank requires the full form and your remittance is above ₹5 lakh. This typically costs ₹2,000–₹10,000 depending on the CA. Annoying but not complex.

How to actually file Form 15CA (if you need to)

Form 15CA is filed on the Income Tax Department's e-filing portal — not at the bank, not in a physical form.

Path on the portal: e-Filing portal → e-File → Income Tax Forms → Form 15CA

Steps:

1. Log in to the IT e-filing portal with your PAN credentials.
2. Navigate to e-File → Income Tax Forms → File Income Tax Forms → Form 15CA.
3. Select the appropriate Part (A, B, C, or D) based on your remittance.
4. Fill in the remittance details: amount, purpose, remittee name, remittee country, bank details.
5. If filing Part B or Part C, you will need the acknowledgement number of the Form 15CB filed by your CA — get the 15CB first.
6. Submit and download the acknowledgement. Hand this to your bank.

For Part A (under ₹5 lakh, no CA needed), the process takes about 15 minutes if you have your passport and bank details handy.

When you actually do need Form 15CA/15CB as an investor

The exemption covers investment outflows. There are scenarios where the exemption does not apply and 15CA/15CB is genuinely required:

Rental income from Indian property remitted abroad: If you own a flat in India and rent it out, that rental income is taxable in India (under Income from House Property). If you then remit that money to a foreign account, the remittance has an Indian tax implication — 15CA/15CB applies.

Loan repayments with foreign-source interest: If you borrowed money from a foreign party and are remitting repayment including an interest component, the interest portion may be a taxable payment to a non-resident — triggering TDS and 15CB requirements.

Consulting or professional fee payments to foreign individuals: If you are an Indian entity paying a foreign consultant or professional, and the income is connected to India, 15CA/15CB applies to the fee payment.

Commission, royalty, or technical fee remittances: These are standard Section 195 scenarios — always require 15CA and usually 15CB.

For these, the rule is not just the bank's internal policy — it is a genuine legal requirement under Section 195, and skipping 15CB creates tax risk.

The RSU situation: why this is the employer's problem, not yours

If you work for a company that grants RSUs and the perquisite value is taxed at vest in India, you may wonder whether you need to do anything around 15CA/15CB when:

1. The shares vest and your employer withholds tax from your salary
2. You later sell the shares and the broker remits proceeds to India

On vest, the employer's payroll team and their CA handle the withholding compliance. If the employer routes RSU shares or proceeds through a payroll mechanism, the employer's CA files Form 15CB as part of the perquisite withholding compliance. You receive the net shares or net cash — the 15CB is the employer's documentation obligation.

When you sell the shares later and receive proceeds in your US brokerage account, and then transfer those proceeds back to India, that is an inward remittance — money coming into India. Inward remittances do not require Form 15CA or Form 15CB at all. The forms only apply to outward foreign remittances.

The only scenario where you personally file 15CA for RSU-related money is if you are an RSU holder who has already received foreign-currency income in a foreign account and then wants to remit it further abroad (for example, transferring from your US broker account to a third country) — but this is a niche scenario and not relevant to most employees.

Using platforms like Vested, INDmoney, or Groww Global

If you invest in US stocks through one of these regulated platforms, the LRS remittance is handled end-to-end by the platform in partnership with their banking partner. You fill out a remittance form on the app, provide your PAN and address proof once at KYC, and the platform handles:

• The A2 form with the correct LRS purpose code
• The bank's internal compliance process
• Form 15CA filing (where the bank requires it, which is rare on these platforms)

You do not personally file Form 15CA when using these platforms. The banking partner's process already satisfies the bank's requirements, and because the remittance is correctly categorised under an investment purpose code, it typically falls under the Rule 37BB(3) exemption anyway.

If you use Interactive Brokers or another direct foreign broker through your Indian bank's LRS wire process, the flow is:

1. You instruct your bank to wire funds under LRS to your IBKR account.
2. The bank processes an A2 outward remittance form with the LRS purpose code (usually S0001 for equity).
3. The bank may or may not ask for Form 15CA — most digitally-oriented private sector banks do not, because the purpose code is exempt.
4. If asked, file Part A if under ₹5 lakh; work with a CA for Part B/C if the bank insists and you are above ₹5 lakh.

The common misconceptions

"I read online that every LRS remittance requires Form 15CA."

This circulates widely on CA forums and social media, often written by professionals who practice in the high-value remittance space (business payments, royalties) where 15CA genuinely applies. The Rule 37BB(3) investment exemption has existed since 2013 and applies specifically to LRS investment outflows. The blanket statement is wrong for retail investors using LRS for shares.

"Form 15CB always costs ₹5,000–₹10,000 and you just have to pay it."

You only need Form 15CB if you are filing Part B or Part C of Form 15CA. If you are under the ₹5 lakh threshold, you file Part A with no CA involvement. If your purpose code is in the Rule 37BB(3) exempt list, you need neither. Many investors have paid for 15CB certificates they legally did not need.

"My bank said it is mandatory, so it must be the law."

The bank's internal policy is not the same as the statutory requirement. Banks are conservative institutions. Their compliance team's instructions to frontline staff often reflect a worst-case interpretation of the rule, not the specific exemption your remittance qualifies for. The legal basis for the 15CA/15CB system is Rule 37BB; the bank's requirement is layered on top of that.

"Filing Form 15CA online is complicated and needs a CA."

Part A of Form 15CA — which covers remittances under ₹5 lakh — requires no CA. It is a self-declaration filed on the IT portal. For most retail investors who send money in tranches, Part A is all that is ever needed even if the bank asks for a 15CA.

Form 15CA Part A vs Part B vs Part C vs Part D

Part A: Remittances not in the exempt list where aggregate LRS does not exceed Rs 5 lakh in the financial year. No Form 15CB required. Self-declaration only on the IT portal. Takes 15 minutes. No CA fees. If your bank asks for 15CA for an investment remittance and you have sent under Rs 5 lakh this year, this is your path.

Part B: Remittances above Rs 5 lakh where the payment is not taxable in India or is covered under DTAA. Requires Form 15CB from a CA. Applicable to business payments, royalties, technical fees — rarely to retail investment LRS.

Part C: Remittances above Rs 5 lakh where the income IS taxable in India and the remitter is withholding TDS. Requires Form 15CB. Applies to employers paying fees to foreign parties, not to individual investors.

Part D: Remittances covered by Rule 37BB(3) — the exempt list. No form to file; the bank records the remittance under the exempt purpose code. S0001 and S0003 LRS investment remittances land here. Banks sometimes ask for Part A anyway — this satisfies their checkbox at minimal cost.

LRS transactions: exempt vs requiring 15CA/15CB

Transaction	Purpose Code	15CA required?	15CB required?
Buy listed US stocks (NYSE/NASDAQ)	S0001	No — Rule 37BB(3) exempt	No
Buy US ETFs on listed exchanges	S0001	No — Rule 37BB(3) exempt	No
Buy US bonds / debt securities	S0003	No — Rule 37BB(3) exempt	No
Education remittance (tuition)	S1301	No — Rule 37BB(3) exempt	No
Travel abroad	S0301	No — Rule 37BB(3) exempt	No
Invest in unlisted US company shares	S0001 (unlisted)	Yes	Yes
Purchase of foreign property	S1401	Yes	Yes
Royalties or technical fees to non-resident	S0205	Yes	Yes
Gift remittance above Rs 5 lakh	S1002	Yes	Yes

Key dividing line: listed securities are exempt; unlisted investments, property, and most business payments are not.

The bank's SWIFT process for LRS and where 15CA fits

When you instruct your bank to wire $5,000 under LRS to your broker:

1. A2 form: You complete the RBI's A2 outward remittance form, declaring purpose code (S0001 for equity), amount, and recipient.
2. Internal compliance: The bank's team reviews the A2. For S0001 investment LRS on digital portals, most private banks approve without additional documentation.
3. SWIFT MT103: The bank initiates the wire to your broker's correspondent bank. The LRS purpose code is recorded in the SWIFT message.
4. RBI reporting: The bank reports to the RBI. Your remittance is tracked against your $250,000 annual LRS limit across all banks.

Form 15CA, if required, is submitted to the bank before step 2. For Part D (exempt) remittances, this step does not exist.

Common bank rejection scenarios and how to handle them

"We cannot process LRS without Form 15CA." Tell them: "This is an investment in listed equity securities under LRS purpose code S0001. Under Rule 37BB(3) of the Income Tax Rules, 1962, this category is exempt from Form 15CA." If the branch persists, escalate to the bank's Forex desk. Alternatively, file Part A (under Rs 5 lakh, no CA) to satisfy their checkbox.

"We need Form 15CB for amounts above Rs 10 lakh." The Rs 10 lakh threshold is the bank's internal policy, not a statutory requirement. Rule 37BB(3) has no monetary limit for exempt remittances. You can push back with the legal text or engage a CA for Part B at Rs 2,000-5,000 and move on.

"LRS not processed — KYC not updated." This is a separate issue from 15CA. Update your KYC (PAN, address, Aadhaar linking) at the branch and retry.

Does not filing 15CA affect your ITR-2?

No direct impact. Form 15CA is a pre-remittance compliance document. The LRS outflow is a capital transaction, not an income event. Your ITR-2 reports income earned on foreign investments (dividends, capital gains) under Schedule FSI, Schedule CG, and Schedule OS — not the remittance itself.

Indirect implication: the department knows you made an LRS investment remittance (from the bank's RBI reporting and AIS). They expect corresponding investment income in your ITR. A large LRS balance abroad with zero foreign income disclosure in your ITR is an AIS mismatch risk. File Schedule FSI and Form 44 for any foreign-source income regardless of whether the original LRS remittance was exempt from 15CA.

The one-paragraph summary

If you are an Indian resident sending money under LRS to buy US stocks or ETFs: your remittance almost certainly falls under the Rule 37BB(3) exempt list (purpose codes S0001 or S0003), meaning you legally do not need Form 15CA or Form 15CB. If your bank asks for it anyway, that is the bank's internal compliance requirement. Handle it with Part A of Form 15CA (no CA needed, free, 15 minutes on the IT portal) if you are under ₹5 lakh for the year — or switch to an LRS-enabled investment platform like Vested, where the bank side is handled for you and this question never arises.
