Can a Form 15CB certificate be issued after the money has already left?
The certificate is built to sit in front of the remittance: it states the nature of the payment, the treaty article relied on and the rate applied, and the bank reads it before releasing funds. Once the money has gone a certificate can still be prepared, but it is written about facts that already exist rather than facts being planned, and the accountant signing it carries the analysis either way. That is why a retrospective file takes longer to assemble. The characterisation has to be evidenced from the contract and the payment records as they stood on the remittance date, not chosen afterwards to suit the rate that was used.
My bank released the transfer without a certificate — what now?
Work backwards in the order the certificate would have been produced. Establish what the payment was for, whether it was taxable in India at all, and whether a treaty article reduced the rate. Then compare that with what was actually withheld, if anything. Where the withholding falls short, the shortfall and the interest on it are the remitter's to fund; the bank's willingness to process the transfer does not move that obligation. The reporting is completed late on the same analysis. A file that shows the characterisation and the article relied on is what makes the late position defensible if it is examined.
Is there a penalty if no tax was owed on the remittance?
Yes, in the sense that exposure on this kind of filing is charged by reference to the form and the delay rather than to the tax. A remittance correctly outside the Indian net, or correctly reduced to nil by a treaty article, still needed its paperwork done before the funds moved. So a nil tax position removes the tax and leaves the form. That is worth knowing before you decide a late certificate is not worth chasing: it is usually less costly to complete the analysis, evidence the nil result and close the year than to leave an unexplained transfer sitting in the bank's records.
Who carries the risk on a late certificate, me or the accountant?
Both, in different places. The accountant who signs takes responsibility for the taxability and withholding analysis in the certificate, which is the professional opinion the bank relies on. The obligation to have withheld correctly on the payment, and to fund any shortfall with interest, sits with the remitter. That split is the reason a retrospective certificate is sometimes refused by whoever signed the earlier ones: they are being asked to opine on a payment they did not see in advance. Expect to supply the contract, the invoice and the remittance advice before any accountant will certify a payment that has already gone out.
Does one certificate cover a series of monthly payments?
Read what the certificate actually says. It records the nature of a payment, the article relied on and the rate applied to it. A later payment of the same nature under the same contract is the same analysis; a payment of a different nature is not, and the earlier certificate does not travel to it. In practice the trouble arrives when a contract is varied, a new service line is added, or a one-off reimbursement is paid on the same invoice run, and the file still holds only the original certificate. That gap is what surfaces as a late filing a year or two later.
How far back can missing certificates be brought up to date?
There is no point at which the file stops being worth completing, because the records the analysis rests on do not improve with age. The practical limit is evidential. Contracts, invoices, correspondence about what was being bought and the bank advice for each transfer are what allow a characterisation to be certified now for a payment made then. Where those survive, a series of years can be reconstructed and reported in one exercise. Where they do not, the honest position may be a more conservative characterisation than the one originally applied, with the difference funded. Start from the documents and see what they support.
How do I get back tax withheld in another country?
By the route that country provides, and it is rarely automatic. Where an elective return is available — on rent or pension income, for instance — filing it recomputes the tax on net income and refunds the difference. Where it is not, you file a refund claim with the withholding authority, supported by evidence of your residence and entitlement to the treaty rate. Both take time, which is why fixing the rate before payment is worth more. See withholding refund and recovery.
How does a remittance actually work, and is it taxed?
A remittance is a transfer of money, not a category of income, and moving your own funds between your own accounts is not what creates tax. What can create tax is the income behind the money and the rules of the country it leaves. India, for instance, collects tax at source when a resident individual remits abroad under the Liberalised Remittance Scheme, and requires certification before certain payments leave. The transfer is the trigger for paperwork rather than for tax. See the LRS and tax collected at source.
