This is where the free zone advantage genuinely still exists — but it is narrower and more conditional than the marketing suggests.
The baseline. UAE corporate tax is 9% on taxable profit above AED 375,000. Below that threshold, the rate is 0%. This applies to mainland companies and, by default, to free zone companies too.
The free zone exemption. A free zone company can access a 0% rate on “Qualifying Income” if it meets the conditions for a Qualifying Free Zone Person: adequate substance in the free zone, qualifying activities, transfer pricing compliance, and staying within the de minimis limits for non-qualifying revenue. Income outside those conditions is taxed at 9%. Crucially, income earned from mainland UAE customers is generally not qualifying income — which loops straight back to the trading question above. A free zone company that quietly serves the local market can lose the exemption it was set up for.
The 2026 update that matters most to small businesses. Small Business Relief lets a UAE business with revenue at or below AED 3 million elect to be treated as having no taxable income for that period — effectively 0% corporate tax, with a simplified compliance burden.
This relief was originally legislated to end with tax periods ending on or before 31 December 2026. It has been extended. Ministerial Decision No. 131 of 2026, issued on 29 July 2026, extends Small Business Relief to tax periods ending on or before 31 December 2029.
Most other Dubai business setup blogs still say this relief expires this December. It does not. For a startup setting up in 2026 that is three additional years of runway — and it substantially weakens the “set up in a free zone for the tax” argument, because a mainland company under AED 3 million in revenue can now elect into the same effective 0% position through 2029.
One caveat worth stating plainly: electing for Small Business Relief means you cannot use tax losses or certain other reliefs in that period. For a business approaching the AED 3 million line, that trade-off is worth modelling with an accountant rather than assuming.
