Can an NRI even give the guarantee? (the 2026 rules)
Yes, but check the date on whatever guidance you are reading. Guarantees given by a person resident outside India are now governed by the Foreign Exchange Management (Guarantees) Regulations, 2026, which came into force on 6 January 2026 and replaced the long-standing 2000 regulations. Almost every article online still cites the old regime, so it is easy to act on stale rules.
Under the current position an NRI can stand as surety for a resident's or an Indian company's obligation, provided the underlying transaction is itself permitted under FEMA and the arrangement fits the external commercial borrowing framework, with a relaxation where the guarantee is fully backed by a counter-guarantee or collateral from the non-resident. There is also new reporting: issuance, modification and invocation of such guarantees are reported to the RBI on a quarterly basis. Because the detail is fresh and fact-specific, the sensible step before you sign is to have the exact conditions and reporting checked against the 2026 regulations, not against a pre-2026 blog.
What it costs you in tax: commission, and invocation
In most family cases the guarantee sits unused and there is no income and no tax. Tax enters in two situations.
First, if you charge a guarantee commission for standing surety, that fee is income. Where it is Indian-source, because the payer and the risk are in India, the Indian payer should withhold TDS under Section 195, the section for payments to non-residents, and a treaty may reduce or reallocate it. The source of a guarantee commission is legally debatable, so this is the conservative, payer-safe position rather than a settled rule. Second, if the borrower defaults and you, the NRI guarantor, pay the bank, that payment is not itself a loss you can write off; RBI's established position is that it becomes a loan owed by the borrower to you. The borrower repays it into your NRO account, from where you can repatriate it within the USD 1 million per financial year NRO route with the usual tax paperwork. If you then charge the borrower interest on what they now owe you, that interest is Indian-source income, taxable, and again within Section 195 when it is paid. A practising CA sets the guarantee up FEMA-compliantly, decides whether to charge commission and how it is taxed, and, if it is ever invoked, structures the repayment and repatriation cleanly.
