NRI Tax Clearance Certificate: Who Actually Needs One and What Form 15CA/15CB Really Does
Most NRIs never need a tax clearance certificate. Learn who actually does under Section 230, the Form 30A process, and when Form 15CA/15CB applies to remittances.
Here is a situation that plays out regularly. An NRI returning to the UK after a three-week India visit reads something online suggesting she needs a "No Objection Certificate" from the income tax department before she can leave. She has an NRO account, earned rental income during the year, and sold a small parcel of shares. She spends three days in a panic trying to locate the right officer and understand what certificate she needs.
She needed nothing. The certificate she read about applies to a different class of person entirely, and the document that actually governs her remittances back to the UK is a separate Form 15CB from a CA, not a clearance to leave the country. These two concepts, a Section 230 tax clearance and a Form 15CA/15CB for remittances, are consistently conflated, and the conflation causes real disruption.
The 30-second answer: Section 230 of the Income Tax Act, 1961 requires a No Objection Certificate or tax clearance certificate only for specific categories of persons with outstanding demands, pending proceedings, or who came to India expressly to conduct business and earn income. Most NRIs visiting India do not need this certificate at all. The requirement is not triggered by holding an NRO account, earning rental income, or realising a capital gain during a visit. The certificate most NRIs actually encounter is the Form 15CA / Form 15CB combination required for outward remittances from India above USD 5,000, which is a tax-compliance declaration for a specific payment rather than a clearance to leave the country. If you are a director of an Indian company with outstanding tax liabilities, or if the Income Tax Department has raised a specific demand against you, the Section 230 route matters. Otherwise, the only paperwork you are likely to need at the remittance stage is Form 15CA filed online and a Form 15CB from your CA.
This guide separates the two concepts completely, explains when Section 230 does and does not apply, walks through the Form 30A application process for the minority who genuinely need it, and then covers the Form 15CA / Form 15CB regime for outward remittances in the detail NRO account holders actually need.
What Section 230 actually says, and who it actually covers
Section 230 of the Income Tax Act, 1961 is titled "Tax clearance certificate." It empowers the government to require certain categories of persons to obtain a certificate from the tax authorities before leaving India, or before certain transactions. The provision has been on the books for decades, but its scope is narrower than most people assume.
Section 230(1) provides that the income tax authorities may require any person, other than a person not domiciled in India, to obtain a tax clearance certificate if they have a tax demand outstanding against them or are under investigation. Section 230(1A), inserted later, extends this to "such class or classes of persons" as the Central Government may notify.
The current notification, issued in 2004 and periodically updated, lists the categories. In practice the categories that matter for NRIs are:
Persons with outstanding tax demands or arrears. If the Income Tax Department has raised a demand against you that is not stayed, not paid, and not under active appeal, you are in scope. An outstanding demand of any quantum, not just a large one, can put you in this category. Check your outstanding demand register on the income tax portal (under the "Pending Actions" tab when you log in with your PAN) before any extended India stay where your departure date matters.
Persons under investigation for serious offences. If search and seizure proceedings have been initiated, a survey conducted under Section 133A, or a notice under Section 131 issued in the context of a serious offence, the department can require a clearance before departure. This is not a theoretical risk for someone with unexplained offshore income or undisclosed assets, and it is an area where legal advice before travel is simply necessary.
Persons who came to India in connection with business. This is the category most often misapplied. If a non-resident came to India specifically to conduct business, conclude transactions, or earn income from an Indian source in connection with that business, Section 230(1A) and the notifications can bring them into scope. This does not mean an NRI visiting family who happens to check in on a property she rents out. It means a person whose visit has a specific commercial purpose, typically formalised, and who will derive income from that purpose.
Directors of companies in default. If you are a director of an Indian company that has outstanding income tax liabilities, is under investigation, or is the subject of assessment proceedings, you may be required to obtain clearance before leaving India. This is one of the higher-risk categories for working NRIs with Indian company directorships, and it is frequently overlooked.
Company directors or managing agents of companies in arrears. Similar to the above, but extends to managing agents where the company carries outstanding demands.
The critical boundary is what is not in this list. Holding an NRO account is not in the list. Owning property in India is not in the list. Earning rental income is not in the list. Selling shares or mutual funds during an India visit is not in the list. Filing an ITR for India income is not in the list. An NRI who visits India, receives rent on an NRO account from a tenant, earns FD interest, and departs at the end of the month has no Section 230 obligation whatsoever. The TDS has been deducted at source by the bank or tenant, the tax is covered, and there is no outstanding demand. The absence of any document certifying this is not a gap in the person's compliance. It is simply evidence that no certificate was required.
The Form 30A process for the minority who do need a clearance
If you genuinely fall into a covered category, the instrument is Form 30A, the application for a tax clearance certificate. The certificate itself, once issued, is sometimes called a No Objection Certificate (NOC) in informal usage, though the statutory form is different from an NOC in other legal contexts.
The application runs through your jurisdictional Assessing Officer, who for non-residents is typically in the International Taxation range. The Form 30A asks you to disclose:
- Your name, address, PAN, and residency status
- The estimated total income from India in the current and immediately preceding financial year
- The tax paid, TDS deducted, and any amount outstanding
- The nature of the business or activity in India that brought you into the covered category
- The date and purpose of travel
You attach supporting documents: ITRs for the preceding years, Form 26AS, evidence of TDS deducted at source, payment challans for advance tax and self-assessment tax, and a copy of any demand notice if a demand is the trigger.
The officer reviews the application and, if satisfied that no tax is payable or that the outstanding demand is settled, issues the clearance certificate. If a demand exists, the officer may require payment or a satisfactory arrangement (such as a bank guarantee in some cases) before issuing the certificate. There is no fixed statutory timeline equivalent to the 30-day instruction under Form 13, so processing depends on the officer's workload and the complexity of your position. For anyone who genuinely needs this certificate and has a time-sensitive departure, applying two to three weeks in advance and staying in contact with the officer (or a CA who has access to the officer) is the practical approach.
The process can be compressed in genuine emergencies, a medical situation or a family crisis, but it requires in-person engagement and there is no online self-service route as there is for Form 13.
The more common situation: Form 15CA and Form 15CB for outward remittances
Separate entirely from Section 230, and relevant to a far larger number of NRIs, is the requirement under Section 195(6) read with Rule 37BB that the person responsible for making a payment to a non-resident, or a person remitting funds from India to a foreign account, must furnish information in a prescribed form before making the remittance.
The two forms are:
Form 15CA is an online declaration filed by the remitter (the person sending money out of India, or the NRO account holder authorising the transfer) on the income tax portal before the remittance is made. It covers the nature of the remittance, the applicable provision of the Act or treaty, the amount, and a declaration that the applicable tax has been paid or deducted. There are four parts, labelled Part A through Part D, and which part applies depends on the amount and nature of the remittance.
Form 15CB is a certificate issued by a practising chartered accountant certifying the nature and purpose of the remittance, the applicable DTAA provisions if any, that the applicable TDS has been deducted at the correct rate, and that the funds are from a taxable or non-taxable source as the case may be. This is essentially the CA's assurance to the bank that the tax treatment of the remittance is correct.
When is Form 15CB required alongside Form 15CA?
Not every Form 15CA filing requires a Form 15CB. Rule 37BB carves out a list of 33 specified purposes for which no Form 15CA or 15CB is needed at all (covering payments like family maintenance, medical expenses below specified limits, and certain imports), and for remittances that are not chargeable to tax in India, Part D of Form 15CA is filed without a CA certificate.
For remittances that are potentially chargeable to tax in India, the practical threshold banks apply is USD 5,000 per remittance. Transfers below this amount are typically processed with a simpler declaration. Above USD 5,000, the bank's compliance desk will require the Form 15CA reference number (generated when you file the form on the income tax portal) and, in most cases, the Form 15CB signed and stamped by your CA.
For NRO account repatriation, particularly from property sales, rental income accumulated over years, or significant fixed-deposit interest, Form 15CB is almost always required. The CA will review the source of funds, the TDS deducted (and reflected in Form 26AS), any exempt income, and the applicable treaty position before certifying. Repatriation from property sale proceeds is effectively always in this category: the amounts are large, the income is capital in nature, and the bank will not move without a CA certificate.
For routine NRO-to-NRE transfers of smaller amounts representing income already fully taxed at source, some banks accept the simpler Part A filing without a CA certificate if the remittance for the year does not exceed Rs 5,00,000. Confirm your bank's specific threshold and process before the transfer, because banks differ in how conservatively they interpret the rule.
A worked example: Anita's NRO repatriation
Anita, an NRI in Canada, sold a plot of land in Gurgaon in FY 2025-26 for Rs 80,00,000. The buyer deducted TDS of approximately Rs 11,96,000 under Section 195 at the long-term rate (she had held the land for more than 24 months). Her indexed cost of acquisition was Rs 55,00,000, making her long-term capital gain Rs 25,00,000. After tax on the gain, her net proceeds, minus TDS, are sitting in her NRO savings account.
She wants to wire the equivalent of approximately USD 90,000 (roughly Rs 75,00,000) to her Canadian account.
Step 1: Verify the TDS in Form 26AS. Before anything else, Anita logs into the income tax portal and downloads her Form 26AS for FY 2025-26. She confirms that the buyer's TDS deposit of Rs 11,96,000 is correctly reflected against her PAN. If there is a mismatch, the CA preparing Form 15CB will flag it, and the bank may hold the transfer while it is corrected. Catching this early avoids the remittance being frozen at the bank's compliance desk. This is covered more fully in TDS for NRIs and refunds.
Step 2: Engage a CA for Form 15CB. Anita's CA reviews the sale documents, the TDS deduction, the capital gains computation, and the ITR she has filed (or will file) for the year. Because the amount exceeds USD 5,000 and the income is chargeable to tax in India (even if TDS has already covered it), Form 15CB is required. The CA certifies the nature of remittance as "repatriation of sale proceeds of immovable property (long-term capital asset)," confirms TDS was deducted at the applicable rate, notes the applicable DTAA if relevant, and signs the certificate. The CA's fee for Form 15CB in a transaction of this nature typically runs between Rs 5,000 and Rs 20,000 depending on complexity and the CA's practice.
Step 3: File Form 15CA online. Anita (or her CA, with her authorisation) logs into the income tax portal and files Form 15CA Part C, the applicable part for remittances above Rs 5,00,000 that are chargeable to tax and require a CA certificate. She enters the remittance details, the Form 15CB details (including the CA's membership number and the certificate date), and submits. The portal generates a 15CA acknowledgement number.
Step 4: Submit to the bank. Anita provides her bank with the Form 15CB (signed physical copy or digitally signed), the Form 15CA acknowledgement number, her passport, PAN card, and the sale deed or purchase agreement as source-of-funds documentation. The bank's outward remittance team reviews and, if satisfied, processes the transfer.
The total amount she can repatriate in a financial year from her NRO account on capital account (which includes property sale proceeds) is subject to the USD 1 million per financial year limit that the Reserve Bank of India imposes on NRO repatriation under FEMA. This limit applies across all her NRO-sourced capital remittances in that year. The Rs 80,00,000 sale value is comfortably within this limit, but for an NRI with multiple India assets being liquidated simultaneously, it is a ceiling worth tracking.
A worked example: Rohit's directorships and the Section 230 question
Rohit is an NRI in Singapore. He is a non-executive director of a mid-size Indian manufacturing company. He visits India twice a year for board meetings. In 2025, the company received an income tax assessment order raising a demand of Rs 1,40,00,000 for AY 2022-23, which the company is contesting before the Commissioner (Appeals). The demand is currently subject to a stay application, but the stay has not yet been formally granted.
Before his next India visit, Rohit's CA in India advises him to check whether he falls within the Section 230 notification categories given the company's pending demand.
This is a situation where the risk is real. As a director of a company with an income tax demand that is not yet stayed, Rohit is potentially in a category where the Assessing Officer could flag his departure. In practice, the department rarely exercises this power against non-executive directors who have no personal outstanding demand, but "rarely" is not "never," and the risk is higher if his name appears in assessment orders or if he is listed as a key managerial person.
His CA's advice: obtain a written confirmation from the company's tax counsel that the stay application is in order, that no personal demands are outstanding against Rohit's own PAN, and check his outstanding demand register on the income tax portal before travel. If his PAN shows a clean demand register and the company's proceedings are at the appellate stage without him being personally named, the risk is low. If any demand shows against his own PAN, he should settle or arrange a stay before departure.
The lesson here is that Section 230 risk for NRI directors is not about their personal India income. It is about their directorship in a company with tax trouble. The personal tax compliance an NRI maintains through ITR filing, TDS, and advance tax does not insulate a director from the company's problems. The residency and tax-status rules that matter for Rohit's personal income are at NRI residency and RNOR rules.
The USD 5,000 threshold: what banks actually ask for
The USD 5,000 threshold that banks apply is not a single statutory number from one source. It is a practical convergence of:
Rule 37BB of the Income Tax Rules, which sets the threshold above which Form 15CA is required for remittances chargeable to tax (the form is required where the remittance exceeds Rs 5,00,000 in the year for specified categories, or for any remittance in the chargeable categories).
RBI's Liberalised Remittance Scheme (LRS) guidelines, which govern resident Indian remittances abroad and use USD 250,000 as the annual ceiling for resident senders, but NRO-to-abroad transfers by NRIs run under FEMA's NRI repatriation provisions rather than LRS.
Banks' own compliance policies, which in many cases apply USD 5,000 as the per-transaction threshold above which they ask for Form 15CA details and, for potentially taxable remittances, a Form 15CB. Below USD 5,000, many banks process with a simpler declaration but they are not legally prevented from asking for Form 15CA/15CB even on smaller transfers if the nature of the funds warrants it.
For practical purposes: if you are remitting anything from an NRO account to a foreign account in any amount that the bank classifies as potentially income-sourced (rent, interest, capital gains, professional income from Indian clients), assume that anything above USD 5,000 will trigger a request for Form 15CA and Form 15CB. Build this into your timeline. Form 15CB requires your CA to sign off, and if your CA needs to review source documents and Form 26AS, allow a week minimum, more if the transaction is complex.
For NRE account transfers to foreign accounts, the position is simpler. NRE accounts hold income that was taxed before being remitted into India (NRE interest itself is exempt), and transfers from NRE to foreign accounts are freely repatriable without Form 15CA or 15CB. The NRE account structure is the cleanest for repatriation, which is why financial advice for NRIs consistently points toward using NRE rather than NRO for funds that do not need to be in India. The account structures are covered in detail in NRE, NRO and FCNR accounts.
What changes under the Income Tax Act 2025
The Income Tax Act 2025, effective April 1, 2026, renumbers and restructures many provisions. The key changes that touch on this guide are:
Forms 15CA and 15CB are renumbered as Forms 145 and 146 respectively under the new Act's provisions on tax collection at source and remittances. The substantive requirement, that a remitter certify the tax treatment of a cross-border payment, is unchanged. Banks are updating their compliance checklists to use the new form numbers; if your bank mentions Form 145 or Form 146, these are the same instruments.
Section 230 on tax clearance certificates is carried forward into the new Act in substantially the same form. The notification categories remain. There is no indication that the government intends to widen the provision to cover routine NRI income, and the practical rarity of its application to ordinary NRI visitors is expected to continue.
The ITR-filing obligations and TDS deduction provisions that feed into both these requirements are covered in NRI ITR filing for AY 2026-27 and advance tax for NRIs.
When to involve a CA and how much it costs
For Section 230 / Form 30A, involve a CA or tax advocate as early as possible if you believe you may be in a covered category. This is not a form you want to complete yourself, because the income disclosures and the officer interaction require professional judgment. Fees vary widely but expect Rs 10,000 to Rs 50,000 for a straightforward application where no demand is contested, and significantly more where negotiation with the officer or appeal is involved.
For Form 15CB, the cost is more standardised. For a remittance arising from routine NRO interest or rent below Rs 25,00,000, expect Rs 3,000 to Rs 8,000. For a property sale or large NRO redemption with complex TDS reconciliation and treaty analysis, expect Rs 8,000 to Rs 25,000. Fees in metropolitan cities are at the higher end of these ranges, and fees from a CA with a specific NRI practice are often worth it because the turnaround time is faster and the bank acceptance rate is higher for certificates from established names.
For Form 15CA without 15CB (for smaller or exempt remittances), a CA may charge a smaller fee to file the online form on your behalf, or you can do it yourself on the income tax portal if you are comfortable navigating the form. The portal's Form 15CA section is under "e-file" and requires login with your PAN and password.
Keeping this clean year on year
The cleanest way to avoid complications with both Section 230 and Form 15CA/15CB over time is to maintain a simple set of habits that most NRI CAs will recommend anyway.
File your ITR every year where you have India income. An up-to-date filing history is the single most useful document in any interaction with the tax department, whether it is an officer reviewing a Form 30A application or a CA certifying a Form 15CB. It demonstrates that income has been declared and tax has been paid. See NRI ITR filing for AY 2026-27 for the current-year process, and NRI belated, revised and updated returns if you have years to catch up.
Reconcile Form 26AS before every major transaction. TDS errors, a buyer quoting your PAN incorrectly on Form 27Q, a bank using an old address, a tenant who filed late, can create mismatches that complicate both your ITR and the CA's Form 15CB work. Download Form 26AS quarterly if you have active NRO income. The process is covered in the TDS for NRIs and refunds guide.
Track your DTAA position. If you hold a Tax Residency Certificate from your country of residence and file Form 10F with deductors, you may be able to claim a lower withholding rate at source, which simplifies the Form 15CB because the TDS is already correct rather than over-withheld and requiring reconciliation. The mechanics are in DTAA mechanics, TRC and Form 10F and DTAA relief for NRIs.
Keep your PAN active. An inoperative PAN, one that has gone inoperative over an unlinked Aadhaar, causes problems across every India tax interaction including Form 15CB preparation and TRACES transactions. Confirm your PAN status on the income tax portal before every tax season and before any significant transaction. The PAN mechanics for NRIs are at PAN for NRIs.
Check your demand register before every India visit where the departure date matters. Log into the income tax portal with your PAN, go to Pending Actions, and confirm that no outstanding demands show against your name. If one does, understand whether it is a genuine liability, a disputed demand, or a system artefact (incorrect TDS mismatch, for example) and have your CA address it before you travel.
The closing read
The confusion between Section 230 tax clearance and Form 15CA/15CB is understandable, because both involve the phrase "tax certificate" in informal usage and both arise at the intersection of India tax law and international movement of money. They are, however, different instruments with different triggers and different consequences for getting them wrong.
Section 230 is the provision to take seriously only if the shoe actually fits. If you have no outstanding demands, are not under investigation, are not a director of a company with tax trouble, and did not come to India specifically to conduct business and earn income from that business, you do not need Form 30A clearance before you leave. The form is not a routine departure formality for NRIs. It is a specific obligation for specific categories of persons, and applying it more broadly than the statute requires creates unnecessary compliance overhead and, in some cases, unnecessary officer interaction.
Form 15CA and Form 15CB, on the other hand, are not optional for remittances above the bank's threshold. Attempting to instruct your bank to transfer funds from an NRO account above USD 5,000 without these forms will result in the transfer being held, not processed and refunded. This is a bank compliance obligation, not a matter for negotiation. Build the Form 15CB timeline into your remittance plan, not as an afterthought once you have already told the recipient the money is coming. A CA who knows your transaction in advance can usually turn a Form 15CB around in three to five business days for a clean transaction; one who hears about it on Friday afternoon before a Monday deadline cannot.
The honest summary of where each instrument matters most: if you have a clean tax record, no demands, no company trouble, and are remitting income that was properly taxed at source, your Section 230 exposure is nil and your Form 15CA/15CB is a five-day administrative task. If either of those conditions is not met, the stakes on each instrument rise sharply, and professional advice before the transaction or the travel date is not optional, it is the first item on the list.

This guide is general information, not personal tax advice. The application of Section 230, the Form 30A process, and the Form 15CA / Form 15CB requirements depend on your specific circumstances including your residency status, the nature of your India income, your directorship positions, any outstanding demands or proceedings, and the policies of your specific bank. Under the Income Tax Act 2025, effective April 1, 2026, Forms 15CA and 15CB are renumbered as Forms 145 and 146 and certain provision references change, while the substantive requirements carry forward. The USD 5,000 threshold applied by banks is a practical compliance convention, not a single statutory threshold, and individual banks may apply different thresholds or documentation requirements. Confirm the current requirements with your bank and a qualified chartered accountant or tax adviser before any significant remittance or before travel if you have any reason to believe you may fall within a Section 230 notification category.
Frequently asked questions
Does every NRI need a tax clearance certificate before leaving India?
No, and this is one of the most persistent misconceptions in NRI tax planning. Section 230 of the Income Tax Act, 1961 requires a clearance certificate or No Objection Certificate only for persons in specific categories: those against whom a tax demand is outstanding or arrears exist, those under investigation for a serious offence, certain categories of persons who have come to India on business or are likely to derive income, and company directors or managing agents where the company is in default or under investigation. The vast majority of NRIs visiting India for family, holidays, or routine financial affairs fall into none of these categories and do not need any certificate before departure. There is no rule requiring you to obtain clearance simply because you hold an NRO account, own property, or earned rental income during your stay.
What is Form 15CA and Form 15CB, and is this the same as a tax clearance certificate?
No, they are completely different instruments serving different purposes. Form 15CA is a self-declaration filed online by the remitter (or NRO account holder) confirming that applicable taxes have been paid or deducted on an outward foreign remittance. Form 15CB is a certificate issued by a chartered accountant confirming the nature of the remittance, the applicable tax treaty provisions, and that taxes have been properly handled. Both are required for most NRO-to-foreign-account remittances above certain thresholds and for payments to non-residents above USD 5,000 that are chargeable to tax in India. Neither is a tax clearance certificate in the Section 230 sense. Form 15CA/15CB is a tax-compliance document for the specific remittance, not a general clearance to leave the country or conduct future business.
When do you actually need a Section 230 No Objection Certificate before leaving India?
You need one if you fall into a notified category under Section 230(1A) or if an Assessing Officer has issued you a specific instruction to obtain clearance. The categories include: persons who have come to India in connection with business and are likely to derive income from a source in India; persons who have been permitted to take up employment or carry on business; and persons against whom proceedings under the Income Tax Act are pending. In practice, most NRIs on a personal visit, even those with NRO accounts, rental income, or capital gains from a property sale that year, are not covered unless the tax department has specifically raised a demand or opened an investigation. If you are a director of an Indian company that has outstanding tax liabilities or is under income tax proceedings, the risk is higher and professional advice before travel is warranted.
How does Form 15CA/15CB work for NRO repatriation, and what is the USD 5,000 threshold?
For remittances from an NRO account or any payment to a non-resident that is chargeable to tax in India, the remitter (usually your bank or you as the account holder) must file Form 15CA online through the income tax portal before the remittance is made. If the remittance exceeds Rs 5,00,000 in a financial year under Rule 37BB, or if it falls into a non-exempted category, a Form 15CB from a chartered accountant is also required. Banks apply a practical threshold of USD 5,000 per remittance, flagging anything above this for Form 15CA/15CB compliance before processing. The CA preparing Form 15CB will verify the source of funds, confirm that TDS has been deducted at the correct rate (or that a treaty benefit applies), and certify the nature of the remittance. NRO repatriation from property sales always requires Form 15CB because the amounts are large and the income is capital in nature. Current-account remittances such as rent or interest may qualify for a simplified Form 15CA without Form 15CB if the total remittance in the year is below Rs 5,00,000, but confirm this with your bank and CA before proceeding.
