There is no US-Saudi Arabia income tax treaty - the two countries have never signed one, and the Tax Information Exchange Agreement the two governments signed in April 2026 explicitly does not create treaty relief; it only lets the IRS and Saudi Arabia’s Zakat, Tax and Customs Authority (ZATCA) share information. For a Saudi Arabia-based investor, that means the full 30% US statutory withholding applies to every US dividend, with no reduced rate available. On the Saudi side, the picture flips entirely: Saudi Arabia imposes no personal income tax, no dividend tax, and no capital gains tax on individuals - Saudi nationals and foreign residents alike. The one thing worth understanding separately is Zakat, a personal religious obligation for Muslim investors that operates completely outside the government tax system.
All three are covered below.
No Treaty: Full 30% US Withholding, No Reduction Available
Because no income tax treaty exists between the US and Saudi Arabia, there is no treaty article to invoke to bring the US withholding rate down. Every US dividend paid to a Saudi Arabia-resident investor is withheld at the full 30% US statutory rate - the same rate that applies by default to any country without a treaty.
Filing Form W-8BEN is still worth doing. As with other no-treaty countries in this series, it doesn’t reduce the 30% rate - there’s no treaty benefit to claim - but it still certifies your non-US status to your broker and avoids the risk of even higher default backup withholding on an undocumented account.
The April 2026 Tax Information Exchange Agreement doesn’t change this. It’s an information-sharing arrangement between the IRS and ZATCA, not a tax treaty - it has no provision reducing withholding rates or offering the kind of relief a full income tax convention would.
Saudi Arabia’s Side: 0% on Dividends and Capital Gains
Saudi Arabia does not impose personal income tax on individuals - a rule that applies uniformly to Saudi nationals and foreign residents alike, and covers dividend income and capital gains from securities, including US stocks. There is no Saudi-side tax return to file on your US brokerage income, no Saudi withholding to track, and no domestic liability to offset against the 30% already withheld by the US.
This means the entire tax cost of investing in US stocks from Saudi Arabia is the 30% US withholding itself - there’s no double taxation to relieve on the Saudi side, because there’s no second layer of Saudi tax to begin with.
Zakat: A Separate, Personal Matter - Not a Government Tax
This is the detail that’s easy to conflate with Saudi Arabia’s government tax system, but shouldn’t be.
Zakat, as administered by ZATCA, applies to businesses - specifically to Saudi and GCC-owned companies, which pay Zakat (typically around 2.5% of a defined zakat base) instead of the 20% corporate income tax that foreign-owned businesses pay. That’s a government-collected business tax, with filing obligations and enforcement behind it.
Zakat on an individual’s personal investment portfolio is a different thing entirely - a religious obligation under Islamic jurisprudence, self-assessed and self-paid by the individual (typically to a charitable purpose), not collected or enforced by ZATCA or any government authority. For a Muslim investor calculating personal Zakat on a US stock portfolio, classical Islamic finance scholarship distinguishes between shares held for investment (assessed, in various scholarly approaches, against the underlying company’s proportionate zakatable assets - cash, receivables, inventory - rather than the full market value) and shares held for trading (typically assessed at the full market value at the standard 2.5% rate). The exact calculation depends on which scholarly methodology you or your religious advisor follow, and is a matter for a qualified Islamic finance or Zakat advisor, not something a general tax guide can specify with a single formula.
The key point for this guide’s purpose: Zakat, however you calculate it personally, is unrelated to the 30% US withholding and to Saudi Arabia’s 0% government income tax rate - the three exist on entirely separate tracks.

Saudi Arabia: Getting the Details Right
Before you place the first trade from Saudi Arabia:
- File W-8BEN with the broker - it certifies non-US status rather than claiming a treaty rate, and prevents backup withholding
- Expect 30% US withholding on every dividend payment, with no treaty-based reduction available
- Don’t expect a Saudi-side tax filing obligation on US dividend or capital gains income - there currently isn’t one
- If calculating personal Zakat, confirm with a qualified Islamic finance advisor whether your holdings count as investment or trading shares under the methodology you follow, since this changes the calculation
- Don’t confuse ZATCA’s business Zakat regime with a personal obligation on your individual brokerage account - they’re administratively separate
- Re-check account-opening requirements with the broker directly before you apply
The Saudi Arabia Position, Condensed
There’s no US-Saudi Arabia tax treaty, so the full 30% US withholding applies to every dividend with no reduction available - W-8BEN still matters for documentation, but not for a lower rate. On the Saudi side, there’s effectively nothing to add: no personal income tax, no dividend tax, no capital gains tax, for Saudi nationals and residents alike. The only additional consideration is Zakat, which is a personal religious matter handled entirely outside the government tax system - genuinely important for a Muslim investor to get right, but not something that interacts with either the US withholding or Saudi Arabia’s 0% government tax rate.
General information on investing from Saudi Arabia; your own circumstances need a professional’s eyes. There is no US-Saudi Arabia income tax treaty; the April 2026 Tax Information Exchange Agreement does not provide treaty-based rate relief. Saudi Arabia’s personal tax rules are set by Saudi law and can change - consult a qualified tax advisor for current guidance, and a qualified Islamic finance or Zakat advisor for guidance specific to your religious obligations.
