The most common mistakes when setting up a business in Dubai are choosing the wrong jurisdiction, putting too few activities on the licence, budgeting only for the licence fee, turning up at the bank unprepared, registering late for corporate tax, and assuming a free zone company pays no tax. All of them cost more to fix than to avoid.
We’ve put them roughly in the order founders tend to make them. The early ones are annoying. The last two can be expensive for years, which is why they get the most space.
Picking the jurisdiction before the customer
The first question is who pays you, and price comes after that. If your customers are UAE consumers or government bodies, you’ll generally need a mainland licence. If they’re overseas or other businesses, a free zone licence usually fits. Offshore companies are for holding assets and can’t run a business in the UAE at all.
People who choose on price alone sometimes end up setting up twice. Moving from a free zone to the mainland later usually means a new licence, a new lease and often new visas. Dubai’s 2025 permit for free zone companies working on the mainland helps some businesses, but it’s something you apply for, not something that comes with the licence.
A licence that’s too narrow
Your licence lists exactly what you’re allowed to do, nothing more. Say you run a marketing consultancy and six months in you want to sell paid training workshops. If training isn’t on the licence, you need an amendment, an approval and a fee before you can invoice for it. Adding closely related activities at the start usually costs little, and many free zones let you combine several from the same group.
Budgeting for the licence and nothing else
The licence fee is one line on a longer bill. Visa entry permits, medicals, Emirates ID, the establishment card, an office or flexi-desk upgrade, document attestation and the first year’s accounting all come on top.
Smart Zone has written before about advertised AED 15,000 packages ending up at AED 35,000 to AED 45,000 once a founder has a visa, a usable office and a bank account. It’s a fair illustration of how quickly the extras add up. Your number depends on visa count and zone. Ask for an all-in quote, in writing, before you commit.
Walking into the bank with just a licence
Banks will want to know who your clients are, where the money comes from and which countries you’ll deal with. A licence doesn’t answer any of that. A one-page business plan, a sample contract or invoice and proof of where the shareholders’ funds came from will. Some businesses (payment-heavy online stores are the usual example) face longer reviews, so it’s worth opening that conversation before the licence is even issued.
Treating the visa as a formality
Each residence visa needs an entry permit, a medical test and Emirates ID biometrics, and any of them can stall on a passport that’s close to expiry or a document that wasn’t attested. Book the medical as soon as the entry permit lands. Landlords and banks will both ask to see the visa, so a delay here tends to spread.
Registering late for corporate tax
Every UAE company must register for corporate tax, including companies that expect to pay nothing. Late registration carries an AED 10,000 penalty (Crowe, citing the FTA), and for most newly incorporated companies the deadline is three months from incorporation.
The FTA has run a waiver for first-time late registrants who file their first return within seven months of the end of the tax period. It’s a useful safety net, but it’s a poor plan. VAT is separate again: registration becomes mandatory once taxable supplies pass AED 375,000 over 12 months (tax.gov.ae). Our VAT services team keeps an eye on both thresholds for clients.
Believing “free zone” means “tax-free”
This is the costliest mistake here, and plenty of setup websites still encourage it.
A free zone company pays 0% only on qualifying income, and only if it meets every condition to count as a Qualifying Free Zone Person. Those conditions include enough real substance in the zone, transfer pricing compliance, audited financial statements, and keeping non-qualifying revenue under the de minimis limit (the lower of 5% of total revenue or AED 5 million). Fail any one and the company is taxed at 9% on all its income for that year and the four years after (PwC Tax Summaries).
Five years is a long time to pay for one slip. And the slips are ordinary ones: selling to individuals in the UAE, picking up a few mainland clients, or skipping the audit because the company feels too small to need one. If your revenue is likely to include mainland or consumer sales, sit down with a corporate tax consultant before you start trading. Doing it after your first return is too late for that year.
