It's one of the most common — and most expensive — misunderstandings in the UAE. A founder sets up in a free zone after being told it's "100% tax-free," assumes there's nothing to register or file, and only discovers otherwise when a penalty appears. That's not the owner's fault; "0% tax" is how free zones are marketed. But marketing is not the law.
Here's the distinction that matters: the famous 0% Corporate Tax rate is a conditional benefit on certain income — not a blanket exemption, and it has nothing to do with VAT. Free zone companies sit fully inside the UAE tax system. The obligations below apply whether or not you ever pay a dirham of tax.
Obligation 1
Corporate Tax: registration and filing are mandatory — for everyone
Under the UAE Corporate Tax Law (Federal Decree-Law No. 47 of 2022), free zone companies are taxable persons. That means two things are non-negotiable, regardless of your tax rate or whether you owe anything:
- You must register for Corporate Tax Every free zone company needs a Corporate Tax registration and a tax registration number. Missing the deadline carries an AED 10,000 penalty. See our Corporate Tax registration service.
- You must file an annual return A Corporate Tax return is due within 9 months of the end of your tax period — even if your tax is 0% and even if you traded nothing. See our Corporate Tax filing service.
The 0% rate is earned, not given
The 0% rate is reserved for a Qualifying Free Zone Person (QFZP). To be one — and stay one — a company must meet every one of these conditions (Cabinet Decision No. 100 of 2023 and Ministerial Decision No. 229 of 2025):
- Maintain adequate substance in the free zone (real staff, premises, and activity — not just a registered address)
- Earn Qualifying Income from qualifying activities or transactions with other free zone persons
- Not have elected to be taxed under the standard regime
- Comply with transfer pricing and arm's-length rules on related-party dealings
- Prepare audited financial statements (IFRS) — mandatory to claim QFZP status, whatever your size
- Stay within the de minimis limit on non-qualifying income
Income that doesn't qualify is taxed at 9%. And if you fail any condition, you don't just pay 9% this year — you can lose QFZP status for the current year and the next four.
⚠️ The de minimis trap that catches consultancies
Non-qualifying income must stay below the lower of AED 5 million or 5% of total revenue in a tax period. Cross it — say, a free zone consultancy that invoices a few mainland clients — and you can lose the 0% rate on all your income for five years. One mis-handled invoice can cost more than your trade licence.
The point
Even a perfect QFZP that pays 0% must still register, keep audited accounts, and file every year. "0% tax" is a rate — not a release from filing.
Obligation 2
VAT: free zones are not VAT-free
VAT (Federal Decree-Law No. 8 of 2017) is a completely separate tax, and for VAT most free zones are treated just like the mainland. The registration thresholds are identical:
| Threshold | Amount | Effect |
|---|---|---|
| Mandatory | AED 375,000 | You must register once taxable supplies + imports exceed this over 12 months, or you expect to within 30 days. |
| Voluntary | AED 187,500 | You may register once taxable supplies, imports, or taxable expenses exceed this. |
Cross the mandatory threshold and you must register within 30 days or face an AED 10,000 penalty. Our VAT registration service handles the full EmaraTax application.
The "Designated Zone" nuance
A small number of free zones are listed as VAT Designated Zones. In these, certain supplies of goods within or between designated zones can fall outside the scope of VAT — but services are generally taxable as normal, and you must still register once you cross the threshold. Most free zones are not designated zones. Check your specific zone before assuming any goods relief applies.
The test everyone asks about
How do you know if a supply is "taxable"?
The thresholds above are measured on taxable supplies — so you need to know which of your sales count. UAE VAT sorts every supply into one of four buckets:
| Category | VAT charged | Counts toward the threshold? | Examples |
|---|---|---|---|
| Standard-rated | 5% | Yes | Most goods & services supplied in the UAE |
| Zero-rated | 0% (still taxable) | Yes | Exports outside the GCC, international transport, certain healthcare/education |
| Exempt | None | No | Certain financial services, residential property (after first supply), bare land, local passenger transport |
| Out of scope | None | No | Supplies made entirely outside the UAE |
The single most common mistake is assuming zero-rated means it doesn't count. It does. A free zone exporter invoicing overseas clients at 0% is still making taxable supplies — and can sail past AED 375,000 while believing it has no VAT obligation at all.
A simple working test: Is it a supply of goods or services, for consideration, made in the UAE, in the course of business, that isn't specifically exempt? If yes, it's a taxable supply (standard or zero-rated) and it counts.
"We only export, so VAT doesn't apply to us" is one of the costliest assumptions a free zone business can make. Exports are usually zero-rated — which is taxable, not exempt.
Obligation 3
VAT filing: once registered, the returns never stop
Registration is the start, not the end. A VAT-registered free zone company must file periodic VAT returns — usually quarterly — within 28 days of the end of each tax period, declaring output VAT on sales and reclaiming input VAT on costs. A "nil" period still requires a return. Late filing starts at AED 1,000 (AED 2,000 if repeated), plus penalties on any unpaid VAT. Our VAT filing service keeps you ahead of every deadline.
Myth vs reality
What you were told vs what the law says
| The marketing | The reality |
|---|---|
| "0% tax, totally tax-free" | 0% applies only to a QFZP's qualifying income; everything else is 9%, and VAT is separate. |
| "Nothing to file" | Corporate Tax registration + annual return are mandatory for every free zone company. |
| "No VAT in a free zone" | VAT thresholds apply like the mainland; designated-zone relief is narrow and covers goods, not services. |
| "We export, so no VAT" | Exports are zero-rated — taxable, and they count toward the registration threshold. |
| "0% means no audit" | Audited financial statements are mandatory to claim QFZP status. |

Your action list
What a free zone company should actually do
- Register for Corporate Tax If you haven't already, do it now — the AED 10,000 penalty applies regardless of your rate.
- Assess your QFZP position Check substance, qualifying income, and the de minimis limit honestly — especially if you invoice mainland or overseas non-free-zone clients.
- Track your taxable supplies Include zero-rated sales. Monitor the rolling 12-month total against AED 375,000.
- Register for VAT in time Within 30 days of crossing (or expecting to cross) the threshold.
- Keep audited accounts Required to claim 0%, and good practice either way.
- File everything on schedule CT annually (9 months after period end); VAT quarterly (28 days after period end).

FAQ
Frequently asked questions
Do free zone companies really have to pay Corporate Tax?
They must register and file regardless. A Qualifying Free Zone Person pays 0% on qualifying income, but 9% applies to non-qualifying income, and the 0% rate depends on meeting strict conditions (substance, qualifying income, audited accounts, transfer pricing, de minimis). "0% rate" is not the same as "no obligation."
Does my free zone company need to register for VAT?
Yes, once your taxable supplies and imports exceed AED 375,000 over 12 months (or you expect to within 30 days). You can register voluntarily from AED 187,500. Free zone status doesn't exempt you — VAT thresholds apply as they do on the mainland.
We only export — do exports count toward the VAT threshold?
Yes. Exports are usually zero-rated, which is still a taxable supply. Zero-rated sales count toward the AED 375,000 threshold even though the VAT rate is 0%, so exporters can be required to register.
What is a VAT "Designated Zone"?
A small list of free zones treated as outside the UAE for VAT on certain supplies of goods. Even there, services are generally taxable and registration thresholds still apply. Most free zones are not designated zones — check yours specifically.
What happens if I never registered because I thought I was tax-free?
Late registration penalties apply (AED 10,000 for Corporate Tax and for VAT), and you may owe back-dated VAT on supplies made after you should have registered. A prompt voluntary approach is almost always cheaper than waiting for the FTA to find the gap — we can help you regularise.
Do the rules differ between IFZA, DMCC, Meydan, JAFZA and other zones?
The Corporate Tax and VAT laws are federal and apply the same across all free zones. The main zone-specific difference is whether your zone is a VAT Designated Zone, which affects the treatment of goods only. The filing and registration obligations are identical.
