In Dubai you pay no income tax. But you must prove to Spain that you really live there.
The UAE levies no personal income tax, no wealth tax and no inheritance tax. That is precisely why the Spanish Tax Agency is especially demanding: to accept that you stopped being a Spanish tax resident, it requires solid proof that you spent more than 183 days in the UAE. And the Emirati certificate (TRC) alone is not enough.
GeoNotary produces that proof: a continuous, automatic expert record of your physical presence, with court validity.

What it takes to be a UAE tax resident
To obtain the Emirati Tax Residency Certificate (TRC), you typically need:
- 183 days of presence in the UAE during the tax year.
- Valid passport, in-force residence visa and Emirates ID.
- Entry-and-exit (immigration) report.
- Accommodation contract (rented or owned).
- Local bank statements for the last 6 months.
To break ties with Spain: do not stay more than 183 days on Spanish territory, do not keep your centre of vital interests there, and report the change via Form 030.
The real risk: a Spanish tax inspection
Spain's Tax Agency applies the tests in article 9 of the Personal Income Tax Act (Law 35/2006), independent of each other:
- 1
Permanence > 183 days: your sporadic absences count as days in Spain unless you prove tax residence in another country with a certificate valid under the tax treaty.
- 2
Centre of economic interests: if your business, income or main assets remain in Spain.
- 3
Family nucleus: if your non-separated spouse and minor children reside in Spain.
With zero-tax destinations such as the UAE, the Spanish Tax Agency pays special attention and the debt becomes time-barred after 4 years. The move may trigger the exit tax (art. 95 bis of the Income Tax Act). An unfavourable residence reassessment with high income easily exceeds €300,000.
Why traditional evidence isn't enough
- Flight tickets: prove the purchase of the trip, not that you boarded or how long you stayed.
- Utility bills: prove consumption, not the holder's personal presence.
- Card statements: prove use, not that you used it in person.
- TRC certificate and visa: party-issued documents; the tax authority requires proof of effective, not just formal, presence.
- Google Maps Timeline: rejected by the tax authority because it is editable by the user.
How GeoNotary solves it
- Continuous, automatic location record: covers all 365 days, with no gaps in the chain of custody.
- Biomechanical verification of the carrier: confirms it was you carrying the device — key for zero-tax destinations, where the tax authority looks for the “phone left in Dubai”.
- Public blockchain sealing + eIDAS timestamp: an unalterable, verifiable record.
- Expert report: admissible before the tax authority, the Economic-Administrative Tribunals and the administrative courts.
Unlike daily-selfie check-in apps, GeoNotary doesn't rely on you remembering to register each day, nor does it leave the days you forget without proof: it records continuously and silently, and certifies who was carrying the device — not just that a phone was somewhere.
