You own a Swiss company's ADR, it declares a dividend of $1.00 a share, and $0.65 shows up in your account. Nobody made an error. Switzerland took its tax first, and the rest of the journey from Zurich to your brokerage statement only shrank the check further. Understanding that first cut, called dividend withholding tax, is the starting point for every other tax question about foreign stocks.
What dividend withholding tax is
Most countries tax dividends that their companies pay to foreign shareholders. Because a foreign tax authority has no practical way to send you a bill in Ohio, it makes the paying company (or its agent) hold back the tax at the moment of payment. That held-back amount is the withholding tax. You never see it as a separate charge; you just receive a smaller dividend.
The U.S. does the same thing to foreign investors who own American stocks, so this is a two-way street rather than a penalty aimed at Americans.
Statutory rate vs. treaty rate
Every country has a statutory rate, the default it applies to any non-resident. Many countries also have a tax treaty with the United States that caps the rate for U.S. residents, usually at 15% for ordinary portfolio holdings. That cap is the treaty rate.
The gap between the two can be large. A few examples as of 2026:
| Country | Statutory rate | U.S. treaty rate |
|---|---|---|
| Canada | 25% | 15% |
| Switzerland | 35% | 15% |
| United Kingdom | Generally none on ordinary dividends | Not needed |

Key point
The treaty rate is a ceiling you are entitled to, not something that happens automatically. Whether you actually get it depends on how your shares are held and whether the paperwork in the chain identifies you as a U.S. resident.
How U.S. investors get the treaty rate (or don't)
When you own an ADR, a U.S. depositary bank holds the underlying foreign shares and pays you dividends in dollars. When you own foreign ordinary shares through a U.S. broker, a chain of custodians holds them. In both cases, the foreign company never knows your name. The treaty rate has to be claimed by someone in the chain on your behalf.
Relief at source
The cleanest outcome is relief at source: the correct treaty rate is applied on the payment date, so the right amount is withheld in the first place. For Canadian securities held through the Depository Trust Company (DTC), U.S. brokers can elect the 15% rate for properly documented U.S. holders through DTC's Elective Dividend Service. Many ADR programs for countries with high statutory rates also offer relief at source, run by the depositary with a specialist tax agent. The Nestle ADR program, for example, uses GlobeTax and lets eligible U.S. holders certify through DTC for the reduced rate, for a small per-ADR fee.
Reclaim after the fact
If relief at source isn't available or the deadline is missed, the full statutory rate is withheld and the excess has to be reclaimed from the foreign tax authority. That process is slower and costs money. We cover it in reclaiming over-withheld foreign tax.
Why you may be over-withheld
Over-withholding usually traces back to one of these causes:
- The ADR is unsponsored or the program doesn't offer relief at source, so the depositary passes through whatever was withheld. See sponsored vs. unsponsored ADRs.
- Your broker didn't make the election or the documentation it held wasn't enough for the foreign country's rules.
- Your address doesn't qualify. Several programs reject P.O. boxes and "care of" addresses as proof of U.S. residence.
- Account type. Retirement accounts are sometimes treated differently than taxable accounts, which can help or hurt. See foreign stocks in IRAs.
Worked example
You hold 200 shares of a Swiss company's ADR that pays the equivalent of $3.00 per share. Gross dividend: $600. With relief at source at the 15% treaty rate, $90 is withheld and $510 reaches you (before any depositary fees). Without it, the 35% statutory rate takes $210 and you receive $390. The $120 difference is not lost forever, but you can't claim it as a U.S. credit; only a Swiss reclaim recovers it.
The general flow, start to finish
- The foreign company declares a dividend in its home currency.
- Withholding is applied at the statutory rate or, if the chain has certified you, at the treaty rate.
- For ADRs, the depositary converts the net amount to dollars and may deduct its own fee. See ADR dividends and currency and ADR fees.
- Your broker credits the net dividend and records the gross dividend and foreign tax withheld.
- After year-end, your Form 1099-DIV shows the gross dividend and the foreign tax paid in box 7.
- On your U.S. return, you can generally claim a foreign tax credit for tax withheld up to the treaty rate. The IRS treats any amount you could have had refunded as not creditable.
Watch out
The credit only covers the tax you legally owed. If a country withheld 35% when the treaty caps it at 15%, only 15% counts toward your U.S. credit. The other 20% is recoverable only from the foreign government, and only within its deadline.
What to check on your own holdings
Pull a dividend from your statement and divide the foreign tax withheld by the gross dividend. If the result is close to the treaty rate, the system is working. If it matches the statutory rate, ask your broker whether the treaty rate was elected and whether the ADR program offers relief at source. Our withholding calculator lets you compare the two outcomes.

Common questions
Why does my 1099-DIV show foreign tax paid on an ADR?
The company's home country withheld tax on the dividend before the depositary bank converted and passed it to you. Your broker reports the amount withheld in box 7 of Form 1099-DIV so you can claim a credit or deduction on your U.S. return.
Do I have to file anything with the foreign government to get the treaty rate?
Usually not. For most holdings at U.S. brokers, the treaty rate is applied at source through the depositary or custodian chain based on your U.S. address and tax documentation. When the full statutory rate is taken instead, getting the difference back usually requires a reclaim.
Is foreign withholding a cost I simply lose?
Not necessarily. In a taxable account, tax withheld up to the treaty rate can generally be claimed as a U.S. foreign tax credit. Amounts withheld above the treaty rate are not creditable and can only be recovered from the foreign country.
