Services across GCC borders: VAT, reverse charge and withholding
Services cross Gulf borders without customs, and their tax is decided by place of supply, evidence and withholding. Here is how it works between the Gulf states and where service firms lose margin.
Where VAT on services is decided
Goods leave a paper trail at every border: declarations, transport documents, inspections. Services leave none. A consultancy in Dubai advising a client in Riyadh, a software company in Bahrain licensing its platform to a retailer in Muscat, an engineering firm in Doha reviewing designs for a project in Abu Dhabi: in each case nothing is cleared through customs, and the VAT position is decided entirely by the rules on the place of supply and by the evidence the supplier keeps about its customer.
Because the GCC's intra-Gulf VAT system has not been switched on, each state applies its own rules and treats the other Gulf states as foreign countries. The general pattern is familiar from Europe: services supplied to a business customer abroad are usually zero-rated by the supplier as an export, and the customer accounts for VAT in its own country under the reverse charge. The details, and the exceptions, differ from state to state, and they are where most errors arise.
When the zero rate applies
In the UAE, a supply of services to a recipient who has no place of residence in the UAE and is outside the UAE when the services are performed can generally be zero-rated as an export, subject to exceptions, for example services connected with real estate in the UAE or with goods located in the UAE. A UAE consultancy advising a Saudi company, with the Saudi client's staff in Riyadh, can usually zero-rate its fee. If the client sends staff to Dubai for a week of workshops, the analysis becomes harder, because the recipient may be present in the UAE when the service is performed.
Saudi Arabia's conditions are stricter and have caused disputes since VAT was introduced. Services supplied by a Saudi supplier to a customer outside the GCC may be zero-rated if the customer has no place of residence in the Kingdom and the benefit of the service is received outside it, and services to GCC customers are treated under the transitional rules as supplied to a non-implementing state, but services connected with goods or property in the Kingdom, or consumed there, remain taxable at 15%. A Saudi engineering firm inspecting equipment on a Saudi site for a foreign owner will typically charge Saudi VAT, whatever the client's location. Bahrain and Oman apply rules of the same family with their own conditions.
The reverse charge
A VAT-registered business that receives services from a supplier outside its own state generally accounts for VAT itself under the reverse charge: it calculates the VAT at its own state's rate, declares it as output tax in its return and, if the service is used for taxable activities, recovers it as input tax in the same return. For a fully taxable business the effect is neutral; for a business with exempt activities, such as some financial services, the reverse charge becomes a real cost. Since January 2026 the UAE no longer requires a self-invoice for reverse-charge supplies, but the supporting documents must be kept.
The reverse charge works only where the customer is registered. A Gulf business supplying services to unregistered customers in another state, typically consumers, cannot rely on the customer to account for VAT, and the question becomes whether the supplier must register in the customer's state. For electronic and digital services supplied to consumers, the answer in Saudi Arabia, the UAE, Bahrain and Oman is often yes: non-resident providers making such supplies are required to register and charge local VAT, generally without a threshold.
Where income tax meets VAT on the same invoice
Cross-border services in the Gulf often attract a second tax that has nothing to do with VAT: withholding tax on payments to non-residents. Saudi Arabia withholds 5% on payments for technical and consulting services to non-residents and higher rates on some other payments, such as 20% on management fees. Qatar withholds on technical fees and on services performed in Qatar, commonly at 5% and 7%. The UAE has no withholding tax on such payments. Bahrain has none today, but its draft corporate tax regime is expected to introduce 5% on interest, royalties and service fees from 2027.
The two layers interact in the price. A UAE consultancy invoicing a Saudi client SAR 100,000 for advisory work may zero-rate its invoice for UAE VAT, see its Saudi client account for 15% VAT under the reverse charge, and still receive only SAR 95,000 because the client withholds 5%. Unless the contract provides for a gross-up, the withholding is the supplier's cost. Treaties can reduce or remove it, but only with a residence certificate and the treaty conditions met. Pricing cross-border services without considering withholding is the most common way Gulf service firms lose margin on each other's markets.
The three questions that decide most cases
The first question is presence. A service firm that sends people to another Gulf state for long projects risks creating a permanent establishment there for income tax, and the same physical presence can change the VAT analysis, because services performed in a state for a customer there may be taxable in that state. Short visits for meetings rarely matter; months on a client's site usually do.
The second is evidence. A zero-rated export of services is a claim the supplier must prove: the contract identifying the customer and its location, proof that the customer is not resident in the supplier's state, and, where the conditions require it, evidence of where the service was used. Authorities increasingly ask for this, and, with the 2026 amendments to the GCC VAT Agreement promising more information sharing between authorities, a zero-rated export in one state with no reverse charge recorded in the other will be easier to spot.
The third is registration. A business making taxable supplies in another state, such as services on local property, digital services to consumers or goods delivered on DDP terms, must register there under that state's rules, and in Saudi Arabia non-residents must also appoint a tax representative. Registration is a commitment to file returns and keep records in that state; it should be planned, not discovered in an audit.
A Dubai agency with clients across the Gulf
A Dubai marketing agency, VAT-registered in the UAE, has three clients outside the UAE. For a Saudi retail chain it designs a campaign from Dubai; the client's team is in Riyadh. The agency zero-rates its fee in the UAE; the Saudi client accounts for 15% VAT under the reverse charge and withholds 5% as the fee is for consulting-type services, so the agency receives 95% of its invoice unless its contract provides for a gross-up. For an Omani bank it runs a two-month on-site project in Muscat; part of the service is performed in Oman, the agency's staff are present there, and it needs to consider whether the supply is taxable in Oman and whether the project creates a taxable presence. For a Bahraini consumer brand it operates a paid subscription app sold to individuals in Bahrain; those are electronic services to consumers, and the agency must consider registering for Bahraini VAT.
None of the three clients is in the UAE, yet each creates a different obligation, and only one is a simple zero-rated export. The agency's fix is a client-by-client map, contracts that address withholding and VAT explicitly, and a registration plan for the markets where it supplies consumers or works on site.
What to write before the first invoice
Most of the problems described here can be handled in the engagement terms. A good cross-border services contract in the Gulf states whether fees exclude VAT and how VAT will be charged or accounted for, says whether fees are paid net of any withholding or grossed up, identifies the customer entity and its country so that the place of supply is clear, sets out where the work will be performed, and requires the customer to provide residence certificates or other documents the supplier needs for treaty relief. These clauses take a page; their absence routinely costs five to fifteen percent of the fee. They are worth reviewing every time a firm wins its first client in a new Gulf market.
Questions we get asked first
Is VAT charged on services supplied from the UAE to a Saudi company?
Generally the UAE supplier can zero-rate the service as an export if the Saudi customer has no residence in the UAE and is outside the UAE when the services are performed, with exceptions such as services connected to UAE property. The Saudi customer accounts for 15% VAT under the reverse charge.
Does Saudi Arabia charge VAT on services exported to the GCC?
Saudi conditions are stricter: services can be zero-rated only where the customer has no residence in the Kingdom and the benefit is received outside it, and services connected with goods or property in the Kingdom or consumed there remain taxable at 15%.
What is the reverse charge?
The mechanism under which a VAT-registered customer receiving services from abroad accounts for VAT itself at its own state's rate and, if entitled, recovers it in the same return.
Do foreign providers of digital services need to register for VAT in the Gulf?
Often yes. Saudi Arabia, the UAE, Bahrain and Oman generally require non-resident providers of electronic services to consumers to register and charge local VAT.
Which Gulf states withhold tax on service fees?
Saudi Arabia (5% on technical and consulting services, higher on some payments) and Qatar (commonly 5% and 7%). The UAE does not. Bahrain is expected to introduce 5% from 2027 under its draft corporate tax.
Can staff working in another Gulf state change the tax position?
Yes. Extended on-site work can create a permanent establishment for income tax and can make services taxable in that state for VAT.
Place of supply, evidence and withholding
Services between Gulf states are taxed as international supplies: zero-rated exports from the supplier's state, reverse charge in the customer's, with exceptions for local property, on-site work and consumers. Withholding tax in Saudi Arabia and Qatar sits on top. Keep evidence of your customer's location, price withholding into contracts, and register where you supply consumers or work on site.
