Foreign dividends: withholding tax and double taxation

When you receive dividends from a foreign company, you are taxed twice: first in the company's country (withholding at source) and then at home. Tax treaties and foreign tax credits prevent much of that double payment, but not always all of it. Understanding how it works helps you choose what to buy and how to report it.

  • The source country withholds part of the dividend; tax treaties often cap it at 15%.
  • At home, the gross dividend is usually taxable income.
  • You can credit the foreign tax paid, limited to the treaty rate and to the home tax on that income.
  • If a country withholds more than the treaty rate, the excess is only recovered by reclaiming it from that country.
  • Inside a fund or ETF, the withholding is borne by the fund and you cannot credit it yourself.

How double taxation works

  1. The foreign company pays the dividend and its country withholds a percentage.
  2. Your broker may also apply home-country withholding on the amount received.
  3. On your tax return, the gross dividend is included in taxable income.
  4. You claim a foreign tax credit (or, in Spain, the international double taxation deduction) for the tax paid abroad, within the limits.
  5. Home-country withholding is deducted as a prepayment.

Example: a US dividend received by a Spanish resident

You receive €1,000 of gross dividends from a US company and have filed the W-8BEN form with your broker so the treaty rate applies:

When a country withholds more than the treaty allows

Some countries apply a default withholding above the treaty rate — Switzerland and Germany are common examples. At home you can only credit up to the treaty rate (usually 15%). The rest is lost unless you reclaim it from that country's tax authority, which usually requires forms, a certificate of tax residence and patience.

Before investing in a country's shares, check its withholding rate and whether your broker applies the reduced rate automatically.

Funds and ETFs

If you invest through a fund or ETF, withholding on the underlying dividends is borne by the fund, not you. It does not appear on your return and you cannot credit it. That is why fund domicile matters: Irish-domiciled funds, for example, benefit from a US treaty that reduces withholding on US dividends.

With accumulating funds, you are also not taxed on the dividends until you sell in many countries. See ETF vs index fund.

How to report it

  • Domestic brokers usually include dividends and withholding in their annual tax statement; check that foreign withholding is shown correctly.
  • With a foreign broker, you report the dividends and foreign withholding yourself using its annual tax statement.
  • Holding assets abroad above certain thresholds may trigger additional reporting obligations.

Frequently asked questions

How much does the US withhold on dividends?

For residents of treaty countries who file a W-8BEN, typically 15%. Without it, withholding is 30%.

Can I recover foreign withholding tax?

Up to the treaty rate, through a foreign tax credit on your home return. Any excess can only be reclaimed from the source country.

Do I have to report dividends from a foreign broker?

In most countries, yes: tax residents are usually taxed on worldwide income.

Do ETFs avoid double taxation?

Not entirely: the withholding is borne by the fund. Some domiciles reduce it, and accumulating funds defer home tax in many countries.
