Imagine a UAE consultancy that finishes a project for a Saudi client. The invoice is paid but the money that lands in the bank is lower than expected. The Saudi client deducted tax before sending it. The owner now worries that the same income will be taxed again at home.
This is an example and not a real case but many owners hit this wall. The UAE-KSA Double Tax Treaty is built for this exact moment. This guide from ebs Chartered Accountants explains in plain words how the treaty works and what paperwork you need to claim withholding tax relief.
What Is the UAE-KSA Double Tax Treaty?
The UAE-KSA Double Tax Treaty is an agreement between the two countries that decides which one can tax certain income and how much. It was signed on 23 May 2018 and reported to apply from 1 January 2020. Its goal is simple. The same income should not be taxed twice in both countries.
For a UAE business this matters when a Saudi payer sends you money for goods or services or royalties. Without the treaty the Saudi side may deduct tax at its normal rate. With the treaty and the right papers the rate can be lower or even nil.
How Does the Treaty Stop Double Taxation?
It works in two ways. First it caps the tax a source country can take on some types of income. Second it gives relief in the country of residence usually as a credit for tax already paid abroad. Reports on the treaty note that this credit method does not cover Saudi Zakat.
The treaty also has a tie-breaker rule. Where a company could be resident in both countries it is treated as resident where it is effectively managed. So your UAE-KSA Double Tax Treaty position starts with proving where your business truly sits.
What Withholding Tax Relief Can You Get?
Withholding tax relief means the Saudi payer deducts less tax or none when it pays you. Reported treaty limits and Saudi domestic rates are shown below.
| Income type | Treaty limit | Saudi domestic rate | What it means |
| Dividends | 5% | 5% | No extra relief |
| Interest | 0% | 5% | Relief available |
| Royalties | 10% | 15% | Lower rate |
Reports also say UAE businesses that provide technical services to Saudi payers can be exempt from Saudi tax as long as they do not create a permanent establishment there. The UAE does not charge withholding tax on dividends. These rates come from published summaries so always check the treaty text before you rely on them.
When Does a UAE Business Create a Permanent Establishment in Saudi Arabia?
A permanent establishment means a taxable presence in the other country. Under the UAE-KSA Double Tax Treaty a service presence can arise when personnel work there for more than 183 days within any 12 months. A building site or installation project creates one when it lasts more than six months.
If you cross these limits the treaty may no longer protect that income. So track the days your team spends in Saudi Arabia from the first visit. Good records protect your withholding tax relief claim too.
Why Do You Need a Tax Residency Certificate?
A Tax Residency Certificate is the UAE Federal Tax Authority proof that your business is a UAE tax resident. The Saudi authority needs it before it accepts that you can use the UAE-KSA Double Tax Treaty. No Tax Residency Certificate usually means no withholding tax relief.
You apply through the EmaraTax portal. Choose the option for double tax treaty purposes and select Saudi Arabia as the other country. Key points from the FTA service page are these.
- A company must be incorporated or established for at least 12 months.
- Documents include a valid licence and lease and a certificate of incorporation and a memorandum of association.
- The electronic certificate takes about 10 business days after a complete application.
- It covers one tax period or a chosen 12-month period.
Always check the FTA page for the latest Tax Residency Certificate rules and fees.
What Is Form Q7B and Why Does It Matter?
Form Q7B is the form businesses have long used to prove residency to Saudi authorities when they claim treaty benefits. One caution matters here. A January 2025 KPMG alert on ZATCA guidance says the newer bulletin does not name.
Form Q7B and refers to a ZATCA-approved request form and a payer undertaking called Form Q7C. So ask your Saudi payer which form ZATCA expects today. Form Q7B may still be requested in practice but do not assume.
How Do You Claim Withholding Tax Relief Step by Step?
Follow this flow.
- Confirm that the income type is covered and that you have no permanent establishment in Saudi Arabia.
- Apply for your Tax Residency Certificate on EmaraTax for treaty purposes.
- Ask your Saudi payer for the form ZATCA wants and complete it with them. Form Q7B is the one many still name.
- Get the form attested by the FTA.
- Complete any further attestation or apostille that ZATCA asks for.
- Your Saudi payer submits the application through the ZATCA portal.
Reported guidance says there are two routes. Relief at source means the payer deducts less from the start. A refund route means tax is deducted first and then claimed back. Relief is not automatic. ZATCA reviews each case.
Quick Tip
Start the Tax Residency Certificate request before you sign the Saudi contract. The certificate needs time and your company must be 12 months old. Early paperwork keeps your Form Q7B and withholding tax relief claim from stalling at payment time.
Can Every UAE Company Claim Treaty Benefits?
Reports on the treaty mention a Principal Purpose Test. Relief can be denied if getting the treaty benefit is one of the main aims of an arrangement. Beneficial ownership also matters for dividends and interest and royalties. A real business with real management in the UAE is in the strongest position.
Reported guidance also says applications should be filed within five years. If you miss that window ZATCA may open an audit. So do not leave old Saudi payments unreviewed. Speak with ebs Chartered Accountants if you want help checking your documents before they go to your Saudi payer.
