15CA/15CB Certification

Sending money out of India is rarely just a bank transfer. The moment your remittance touches a taxable category - a property sale, a software royalty, an interest payment, a professional fee - your bank stops and asks for Form 15CA and Form 15CB. Without them, the SWIFT message never leaves the AD branch.

These two forms are how the Income Tax Department tracks every rupee leaving India and confirms the right tax has been deducted before it goes. Get them wrong and the remittance reverses, the penalty hits one lakh rupees per default, and your CA carries the audit trail. Get them right and the money clears in days.

At a Glance

• Who needs this: Anyone making a taxable foreign remittance - NRIs repatriating property sale proceeds, businesses paying overseas vendors, and importers paying for software, royalties, or technical services.
• Governing law: Section 195 of the Income Tax Act, Rule 37BB, and FEMA 1999 read with RBI Master Directions on outward remittance.
• Forms involved: Form 15CA (declaration by remitter, four parts A, B, C, and D) and Form 15CB (CA certificate confirming tax treatment).
• Turnaround: 3-7 working days from document intake to bank submission, depending on DTAA and TRC complexity.
• Key threshold: Form 15CB is required only if the remittance is taxable AND exceeds ₹5 lakh in the financial year.
• LRS context: Resident individuals are also bound by the USD 250,000 annual LRS cap, with 20% TCS on amounts above ₹10 lakh for non-education or non-medical purposes.
• UDIN locked: Every 15CB carries a unique CA UDIN traceable to the certifying professional and the exact remittance amount.

What's New for FY 2026-27

The CBDT and RBI have tightened the remittance gate over the last 18 months. Here is what shifted before AY 2027-28.

• Form 10F mandatorily e-filed: Non-residents claiming DTAA relief must now e-file Form 10F on the income tax portal. Paper Form 10F is no longer accepted, even for first-time remittees who do not yet hold an Indian PAN.
• AIS auto-validation at filing: The portal cross-checks 15CB data against AIS, 26AS, and TDS challans in real time. Any mismatch in PAN, amount, or TAN now rejects the form before submission.
• TCS-LRS threshold steady at ₹10 lakh: TCS on outward LRS remittances above ₹10 lakh, excluding education and medical, continues at 20%. The collector now reports remittance-wise, so cross-bank aggregation is automatic.
• UDIN locked to remittance amount: ICAI's UDIN portal now requires the certifying CA to record the exact remittance amount. Any subsequent revision creates a fresh UDIN and a visible audit trail.
• NRI repatriation cap reaffirmed: RBI continues the USD 1 million per financial year limit on NRO repatriation. CA certification confirming source-of-funds and tax payment remains mandatory.
• Rule 37BB list refreshed: The list of non-taxable purposes that need only 15CA Part D was reviewed in 2025; some purpose codes were consolidated, others tightened on supporting documentation.

Who Actually Needs 15CA and 15CB

Not every overseas transfer needs both forms. The split is driven by taxability and amount.

• NRIs repatriating Indian assets: Sale proceeds of property, shares, mutual funds, or inherited assets going to an overseas account need 15CA Part C and 15CB without exception.
• Businesses paying foreign vendors: Software licences, royalties, technical service fees, commission, and management charges paid to non-residents all trigger Section 195 and require both forms.
• Importers and service buyers: Even where customs duty is paid, payments for services consumed in India - consultancy, design, cloud hosting - need 15CA and 15CB if the recipient is a non-resident.
• Indian companies paying foreign directors: Director sitting fees, salaries, and reimbursements to non-resident directors fall under Section 195 and need certification.
• Resident individuals under LRS: Most LRS purposes on the Rule 37BB Part D list need only 15CA Part D. Gifts, investments, and loans above ₹5 lakh may still need a CA review for FEMA compliance.
• Trust and estate transfers: Inheritance, gifts to NRIs, and trust distributions to overseas beneficiaries need both forms with extra source-of-funds proof.

How It Actually Works

The workflow runs in parallel across three desks - the income tax portal, the ICAI UDIN system, and the AD bank. Here is the sequence we follow on every file.

Step 1: Remittance Brief and Document Intake

Day one is spent confirming the four anchors that decide everything else: who is paying, who is receiving, what is being paid for, and from which source. We collect the PAN of the remitter, the PAN or TRC of the remittee, the underlying invoice or sale deed, and the AD bank's checklist. NRI files also need passport, visa, and proof that the funds sit in an NRO or NRE account.

Where the purpose code is unclear - technical service versus royalty versus business income - we draft the position in writing before any tax is deducted. This single decision shifts the TDS rate by 10-20 percentage points.

Step 2: Taxability and DTAA Analysis

We test the remittance against Section 9 of the Income Tax Act to confirm whether the income accrues in India. If it does, the Section 195 rate applies. If the recipient's country has a tax treaty with India, we compare the Act rate with the treaty rate and apply the lower one.

DTAA relief is not automatic. It needs a valid TRC from the recipient's tax authority, an e-filed Form 10F, and a beneficial-ownership declaration. We assemble all three before the 15CB is drafted.

Step 3: TDS Deposit and Challan

Where tax is payable, we deposit it under the correct section - 195 for general payments, 194-IA for property bought from an NRI seller - and generate the challan. The challan number, BSR code, and deposit date are then locked into the 15CB working papers so the certificate cannot drift from reality.

For property sales, we also reconcile the TDS already deducted by the buyer through Form 26QB against the seller's actual tax liability and plan a refund where the buyer over-deducted.

Step 4: Form 15CB Certification

The CA logs into the income tax portal, drafts 15CB with the full computation, attaches working papers, and digitally signs the certificate. A UDIN is generated and locked to that specific 15CB.

This is the most reviewable document in the chain. Every figure on it has to tie back to an invoice, a challan, a TRC, or a statute reference. We do not ship until it does.

Step 5: Form 15CA Filing

The remitter then logs in to file 15CA, picks the right Part - A for taxable remittances below ₹5 lakh, B for lower-deduction cases, C for taxable remittances above ₹5 lakh, D for the Rule 37BB non-taxable list - and references the 15CB acknowledgement number.

Part C is the most common for NRI property sales and corporate vendor payments. The acknowledgement is generated instantly and is what the bank wants to see.

Step 6: Bank Submission and SWIFT Tracking

The 15CA acknowledgement, the 15CB PDF with UDIN, Form A2, KYC, and underlying transaction documents go to the AD bank as a single bundle. We track the bank's compliance review until the SWIFT message fires and reaches the beneficiary bank.

A Real Example: NRI Selling Indian Property

Take a concrete case - an NRI selling a Bengaluru apartment in October 2026 and sending the proceeds to a US bank account.

• Sale consideration: ₹2.4 crore, jointly owned with spouse on a 50:50 basis, so ₹1.2 crore each.
• Indexed cost of acquisition: ₹85 lakh per owner after CII adjustment, leaving long-term capital gains of about ₹35 lakh per owner.
• TDS already deducted by buyer: Under Section 195, the buyer deducted 12.5% LTCG plus surcharge and cess on the gross consideration - roughly ₹15.6 lakh on each owner's share.
• Actual tax liability: ₹35 lakh of gains taxed at 12.5% plus surcharge and cess works out to roughly ₹4.9 lakh per owner. A large refund is due.
• Action taken: We apply for a lower-deduction certificate under Section 197 before the next tranche, claim the existing refund through the ITR, and certify 15CB on the net repatriable amount.

Without this workflow, each seller would have lost over ₹10 lakh of working capital for 14-18 months waiting for an ITR refund. The Section 197 route compressed that wait to a six-week certification.

What Backs Up Each Certificate

Every 15CB we sign is supported by a working-paper file the CA can produce on demand. Here is what sits in that file.

• Computation sheet: Line-by-line tax calculation showing the Section 195 rate, DTAA rate, surcharge, cess, and net TDS deducted.
• TRC and Form 10F: Original TRC issued by the foreign tax authority, plus the e-filed Form 10F acknowledgement number.
• Beneficial-ownership declaration: Signed declaration that the remittee is the beneficial owner of the income, with a corporate structure chart where applicable.
• TDS challan: BSR code, challan number, and deposit date for every rupee of tax remitted.
• Invoice or sale deed: Underlying transaction document with stamp duty paid for property, or GST treatment recorded for services.
• AIS and 26AS extract: Snapshot taken on the day 15CB is signed, confirming TDS credits and reported income.

Every 15CB you sign should be defensible in scrutiny five years later. If the working papers are not there, neither is the certificate.

Where It Goes Wrong

The pattern of rejections at the AD bank counter and in scrutiny notices is remarkably consistent. These are the eight failures we see most often.

• Wrong Part of Form 15CA: Filing Part D for a taxable remittance because the purpose code looked similar. Banks reverse this within hours and ask for Part C with a 15CB.
• Treating taxable services as non-taxable: Software-as-a-service and cloud subscriptions are often misclassified as ordinary imports. The 10% royalty or fees-for-technical-services TDS still applies in most cases.
• TRC older than 12 months: DTAA relief denied because the TRC has expired. The treaty rate falls back to the Act rate, costing 10-20 percentage points of tax.
• Form 10F not e-filed: Paper Form 10F is no longer accepted. Filing 15CB on a paper 10F means the certificate is technically defective.
• Mismatch between 15CB and challan: Rounding differences between the computation and the deposited TDS - the portal now blocks the form at submission.
• Skipping Form A2 at the bank: AD banks require Form A2 even when 15CA and 15CB are in order. Without it, the SWIFT instruction is held.
• LRS aggregation ignored: Resident remitters often cross USD 250,000 across multiple banks without realising. The collector's TCS calculation now catches this at source.
• No beneficial-ownership declaration: DTAA benefits denied where the remittee is treated as a conduit. The 15CB is then revised, and the differential TDS becomes payable with interest under Section 201.

How to Get Started

Share the basics first - the remittance amount, the currency, the beneficiary country, the underlying transaction, and your AD bank. A 15-minute call lets us confirm whether you need 15CA Part D alone, the full 15CA-15CB combination, or a Section 197 lower-deduction certificate before any tax is touched.

From there we collect documents through a secure upload link, complete the DTAA analysis, deposit any TDS, certify 15CB, file 15CA, and submit the bundle to your bank. Most files clear in 3-7 working days. Property sales and complex DTAA cases occasionally take 10-12 days where TRC procurement is involved.
