India–UAE cross-border tax: residency, DTAA and business setup.

The UAE hosts the world's largest Indian diaspora and levies no personal income tax — so your entire tax outcome turns on the India side. Residency day-counts, the deemed-residency rule written for Gulf NRIs, treaty claims on Indian income, and the 9% corporate-tax reality behind a UAE company.

The corridor in one paragraph

Money flows both ways: salaries and business profits earned tax-free in the UAE funding property, deposits and investments in India; and increasingly, Indian founders and family offices opening UAE entities for global business. Neither direction is complicated — but each has exactly one trap that catches people repeatedly. Going out, it's residency status. Coming back in, it's round-tripping and substance.

Residency: where every UAE case starts

Because the UAE doesn't tax your salary, your entire tax outcome turns on staying non-resident in India. The mechanics: 182 days in India makes you resident; for visiting NRIs with Indian-sourced income above ₹15 lakh, the limit tightens to 120 days (with a 365-day look-back). And the rule written for this corridor — deemed residency — catches Indian citizens with Indian income above ₹15 lakh who are "not liable to tax" anywhere. Deemed residents land as RNOR, not full residents, so foreign salary generally stays out — but you inherit filing obligations you didn't expect. Long India trips, family events and the Diwali-to-wedding-season weeks add up faster than expected — count them. Run your facts through the residential-status checker annually, not once.

Your Indian income: what the treaty actually does

Your NRE and FCNR deposit interest is already exempt under Indian law while you're a non-resident under FEMA — no treaty needed. Where the DTAA makes a real difference is NRO interest (treaty ceiling 12.5% against the 30%-plus-cess domestic rate), dividends (10%), and royalties or technical fees (10%). Claiming those rates needs a UAE Tax Residency Certificate, electronic Form 41 (Form 10F) and your PAN, handed to the payer before payment. The UAE issues TRCs under its domestic residency rules despite having no income tax — get one each year; it is also your shield on deemed residency. Check any rate on the DTAA rate checker.

Capital gains on Indian shares and property are, in practice, planned on Indian domestic rates — the treaty's gains article has moved through protocol and MLI changes and needs case-by-case reading before anyone relies on it. The NRI capital-gains calculator covers the domestic position; property sellers should read the Form 13 guide before signing.

Setting up in the UAE from India

An Indian resident or company investing into a UAE entity is in FEMA ODI territory: the Overseas Investment Rules, form FC filings through your AD bank, and annual performance reporting. Three structural points dominate:

• Free zone vs mainland. A Qualifying Free Zone Person can hold a 0% rate on qualifying income under the UAE's corporate-tax regime; mainland business is taxed at 9%. The qualifying conditions — substance, audited accounts, activity lists — are real and reviewed annually.
• Substance, or POEM applies. A UAE company managed in fact from Gurugram is an Indian tax resident under POEM. Board meetings, decision-makers and operations need to actually sit in the UAE.
• Round-tripping. A UAE holdco whose main asset is an investment back into India draws FEMA's round-trip restrictions and GAAR attention. If the goal is an offshore-flavoured holding for Indian assets, compare GIFT City first — it exists for exactly this.

Coming home: the RNOR window

UAE returnees typically get two to three RNOR years in which foreign income stays outside Indian tax — the window to restructure deposits (FCNR runs to maturity tax-free), realise offshore gains and re-organise holdings before full residency. The RNOR note walks the sequence, including the FEMA account changes that trigger on return day, not on tax-residency day.

Estate planning across the corridor

Indian succession law follows the person and the asset; the UAE historically applied Sharia principles to local assets. For UAE-resident Indians with meaningful UAE assets, a DIFC or ADGM will covering UAE assets, alongside an Indian will for Indian assets, is the standard two-document answer. India currently levies no inheritance tax; the UAE none either — the planning issue is administration and applicable law, not tax.
