UAE VAT for Foreign SaaS: Zero Threshold and FTA Registration

The United Arab Emirates introduced VAT in 2018 at 5%. What most foreign SaaS vendors miss is that the AED 375,000 mandatory registration threshold only applies to UAE-resident businesses — non-residents face a zero threshold for any taxable supply made in the UAE. If you sell SaaS to a UAE consumer who cannot self-assess VAT, you are required to register with the Federal Tax Authority from the very first transaction. This article walks through the rules and the FTA registration process.

Who the UAE rules apply to

UAE VAT is governed by Federal Decree-Law No. 8 of 2017 and its executive regulation (Cabinet Decision No. 52 of 2017, as amended). Key provisions for foreign SaaS:

• Article 30 — place of supply for electronic services is where the services are used and enjoyed. For a UAE-resident recipient, that is the UAE.
• Article 48 — reverse charge applies where a taxable person in the UAE receives services from outside the UAE. The UAE recipient self-assesses 5% output VAT and claims it as input VAT.
• Article 13(2) — non-residents making taxable supplies in the UAE must register for VAT regardless of the threshold applicable to residents.

Zero threshold: what "from the first AED" means

The AED 375,000 mandatory registration threshold and the AED 187,500 voluntary threshold apply only to UAE-resident persons. For a non-resident foreign SaaS vendor:

• If all UAE customers are VAT-registered businesses → reverse charge applies and the non-resident vendor does not need to register.
• If any UAE customer is not VAT-registered (consumers or unregistered businesses) → the non-resident vendor must register for VAT before making the first supply.

In practice, any SaaS company with a self-serve signup flow that could capture UAE consumer subscriptions needs to either register proactively or build the controls to block UAE consumers until it does.

Step 1: Register through the FTA's EmaraTax portal

Registration is handled through the EmaraTax portal at tax.gov.ae. Non-resident applications select "Non-resident business" as the taxpayer type. Documents required:

• Certificate of incorporation (translated to Arabic if not in English)
• Memorandum of association or equivalent
• Passport and Emirates ID of the authorised signatory (or a Power of Attorney to a UAE-based tax agent)
• Bank account details (foreign bank acceptable for non-residents)
• Estimated annual supplies into the UAE
• Description of services provided

Non-residents are strongly encouraged, though not formally required, to appoint a UAE-registered Tax Agent licensed by the FTA. A Tax Agent handles correspondence, filing submission, and any disputes.

On approval, the FTA issues a Tax Registration Number (TRN), a 15-digit identifier in the format 100XXXXXXXXXXXX.

Step 2: Determine the place of supply

For electronic services, UAE VAT applies where the customer is resident in the UAE. Evidence to establish UAE residency includes:

• Billing address in the UAE
• IP address from a UAE range
• UAE-issued payment card (check the BIN)
• UAE mobile phone country code (+971)
• Use of a UAE bank account for payment

As with the EU, operational practice is to collect at least two non-contradictory items before classifying the supply as UAE-taxable.

Step 3: Invoicing requirements

UAE tax invoices must include:

1. The words "Tax Invoice" clearly displayed
2. Name, address, and TRN of the supplier
3. Name and address of the recipient (and their TRN if VAT-registered)
4. A unique invoice number and the date of issue
5. Description of the supply
6. Net amount, applicable VAT rate, VAT amount, and gross total (all in AED, or with an AED equivalent for foreign currency invoices using the Central Bank of the UAE rate on the invoice date)
7. For reverse charge: the statement "Supply subject to reverse charge under Article 48"

Simplified tax invoices are permitted for B2C supplies under AED 10,000 and can omit some recipient details.

Step 4: Filing and payment

VAT returns in the UAE are filed quarterly by default (monthly for larger taxpayers as directed by the FTA). Returns are due 28 days after the end of the tax period, with payment on the same day. Late filing and late payment penalties start at AED 1,000 per offence and escalate quickly.

Payment is made in AED through the FTA portal (credit card, bank transfer, or GIBAN), and returns are submitted electronically through EmaraTax.

B2B reverse charge: how it reduces your obligation

If all your UAE customers are VAT-registered businesses, Article 48 reverse charge applies to every sale. In that scenario:

• You do not charge VAT on the invoice.
• The UAE customer self-assesses 5% VAT and claims the same amount as input tax.
• You may not need to register (subject to verification of each customer's TRN).

However, any single sale to a non-VAT-registered UAE customer triggers the zero-threshold registration requirement retroactively. Verify each UAE customer's TRN against the FTA's public TRN Verification Service before relying on reverse charge.

Designated Free Zones

The UAE has several Designated Free Zones treated as outside the UAE for VAT purposes (e.g., Jebel Ali Free Zone for certain supplies of goods). For SaaS, the Free Zone rules rarely change the treatment because electronic services to a Free Zone recipient are generally treated as supplied to the UAE. Do not assume a Free Zone customer removes the VAT obligation without checking the specific entity and service type.

Common mistakes

1. Applying the AED 375,000 threshold. It does not apply to non-residents.
2. Skipping TRN verification. Reverse charge depends on the customer being VAT-registered; always validate the TRN.
3. Omitting the reverse charge narrative. Article 48 treatment requires the specific invoice wording.
4. Late filing. FTA penalties accumulate quickly and can include higher-rate interest.
5. Ignoring Oman, Bahrain, Saudi Arabia, and Egypt. The Gulf has several similar regimes with equally strict zero-threshold rules for non-residents.
