The DTAA is not a zero-tax agreement — it coordinates two tax systems. Rates are the endpoint of an analysis, not the starting assumption. And the headline 10% royalty rate from India's 2024 notification cannot simply be copied into a filing.
Rates are the endpoint of an analysis, not the starting assumption. The India-Spain DTAA sets residence and permanent-establishment rules, caps certain withholding taxes and provides mechanisms to relieve qualifying double taxation. The correct result starts with the facts: who pays, who receives, where each is resident, what the payment legally represents, who beneficially owns the income, where work and decisions happen, and whether a PE exists. Only then can the article and rate be selected.
The bilateral convention (signed 1993, later amended by protocol) is now also modified by the OECD Multilateral Instrument (MLI). India and Spain have published a synthesised text; the authentic legal texts prevail. Every cross-border payment passes through layers:
The lower practical burden is not always the printed treaty cap. Domestic law may be lower, an exemption may apply, or the treaty claim may fail because documentation or entitlement conditions are not met.
| Income (article) | Treaty position | What must be checked |
|---|---|---|
| Dividends (Art. 11) | 15% max | Beneficial ownership, residence, domestic exemption or lower rate, PE connection, foreign-tax-credit treatment. |
| Interest (Art. 12) | 15% cap | Beneficial ownership, government / approved-transaction exemptions, arm's-length terms, deductibility, PE connection. |
| Royalties & FTS (Art. 13 + 2024 notice) | 10%* | Correct classification, beneficial ownership, payer-country implementation, PE connection, notification effective date. |
| Business profits (Art. 7) | Source tax if PE | Whether a PE exists and which profits are attributable under the treaty and domestic law. |
These are maximum source-country rates, not the final worldwide effective rate. Entity-level corporate tax, deductibility, transfer pricing, Indian surcharge/cess where relevant, Spanish domestic rules and foreign-tax-credit limits are separate parts of the calculation. And a contract label does not determine the article: a payment called "consulting", "software" or "management fee" is classified from the actual rights, work, risk and evidence.
The earlier treaty wording published in Spain's BOE caps equipment royalties at 10% and other royalties and fees for technical services at 20%. India's Ministry of Finance issued Notification No. 33/2024, substituting Article 13(2) with a 10% cap for royalties and FTS where the recipient is the beneficial owner, effective from assessment year 2024-25.
So the 10% outcome should not be dropped into a Spanish or Indian withholding filing without checking the payer jurisdiction's current administrative position and the applicable period. This is the single most common place a confident-looking rate goes wrong.
Under Article 5, a PE generally means a fixed place of business through which the business is carried on. The MLI broadens and conditions parts of the analysis. The triggers:
A subsidiary does not automatically constitute a PE of its parent, but neither does it wipe out a PE created by the parent's own people, premises or contracting. Finding a PE is also not the end — taxable profit must then be attributed to the Spanish activity. Parent and subsidiary functions are analysed separately.
The MLI modifies the treaty's preamble and adds a principal-purpose test: benefits can be denied where obtaining that benefit was one of the principal purposes of an arrangement, unless granting it would accord with the object and purpose of the provision. Four questions before relying on the treaty:
Article 25 provides credit-based relief — a mechanism, not a guaranteed full refund. The credit is generally limited to the domestic tax attributable to the foreign income; a mismatch in financial year, assessment year, payment date or income classification can delay or reduce usable relief. Model the full tax chain before declaring an "effective rate". And the position must survive after the payment:
Banking and tax records must not contradict each other — a payment presented to a bank as an IP licence cannot later be treated as an undocumented reimbursement without creating questions.
