Oman: the NRI investment guide

Oman-resident NRIs hold a solid Gulf treaty hand — NRO interest capped at 10% (second-best in the Gulf), dividends at 12.5%, no personal income tax today, and mutual fund unit gains assigned only to Oman under the residual-clause reading the ITAT has endorsed for the UAE and Singapore — but Oman is also the Gulf's moving part: a protocol to the treaty applies from this financial year, and from January 2028 Oman becomes the first Gulf state with a personal income tax. Add the usual caveat — no direct case law for this treaty yet — and the guide below covers all of it.

At a glance

You can test every number above against your own figures in the DTAA tax visualizer — select Oman and switch between the income tabs.

Your India tax position, income by income

Mutual fund units. The treaty's shares clause covers shares of Indian companies — but Indian mutual funds are trusts, so units are not shares. Unit gains therefore fall to the residual clause, which assigns taxing rights only to your country of residence; Oman currently levies no personal tax on them. Be clear about the legal footing, though: no tribunal has yet ruled on the India–Oman treaty itself. The ITAT decisions establishing this reading — Saket Kanoi (UAE, 2024) and Anushka Sanjay Shah (Singapore, 2025) — concern treaties with similar capital-gains architecture and are persuasive analogies, but they are themselves under departmental appeal. The Oman position is a reasoned reading, one step less tested than its Gulf neighbour's. The 2025 protocol (effective in India from FY 2026–27) left the capital-gains and dividend/interest articles untouched, but sharpened the treaty's anti-abuse language against arrangements built to shop for benefits.

Direct stocks and PMS. The shares clause keeps gains on Indian-company shares — including shares held through a PMS — taxable in India at the normal rates, regardless of Oman residence. The treaty gives no escape here; this is the sharpest MF-versus-PMS difference for Oman residents.

Dividends and interest. Settled treaty text, no case law needed: MF dividend TDS capped at 12.5% instead of 20%, and interest — most relevantly on NRO balances — at 10% instead of 30%, the second-best interest cap in the Gulf. NRE interest needs no treaty at all: it's exempt under Section 10(4)(ii) while you hold FEMA non-resident status.

Claiming the treaty: the Oman TRC

Everything above is conditional on paperwork. The Oman TRC is issued by the Oman Tax Authority (OTA). The process is less digitised than the UAE's: expect at least one round of in-person document verification at the OTA in Muscat, with residence evidence (visa, residence card, presence records) to support the certified period — so build in lead time rather than applying at the deadline. With the TRC in hand, file Form 10F on the Indian portal for the financial year, share it with your bank and AMC so treaty rates apply at source, and disclose the position in your ITR.

Accounts, disclosure & paperwork

The base kit is the same as any NRI: an NRE and/or NRO account (NRE-funded investments keep redemption proceeds freely repatriable), KYC, and the FATCA/CRS self-certification — Oman participates in CRS, so your Indian account data is exchanged with the Omani authorities, and your declared residence must match your TRC story. Typical onboarding documents: passport, Oman residence card, overseas address proof, PAN, and a photograph; the NRI desk confirms the exact checklist per institution.
