Dividend Tax Calculator (After-Tax Amount)

The amount you actually receive from a dividend payment is almost never the full per-share amount multiplied by your shares. Every country in this calculator withholds tax at the time of payment, and the rate, structure, and even whether that withholding is final all differ by country. This calculator estimates the withholding tax and after-tax amount for South Korea, the United States, Japan, Germany, and Spain, using rates confirmed against each country's tax authority as of August 2026, plus a custom-rate option for any other jurisdiction.

The five countries fall into different patterns. South Korea and Japan use flat rates — 15.4% (14% national income tax plus 1.4% local income tax) and 20.315% (15% income tax, a 0.315% reconstruction surtax, and 5% local resident tax) respectively — applied directly to the dividend amount, with no brackets. Germany also uses a flat rate, 26.375%, combining the 25% Abgeltungsteuer with a 5.5% solidarity surcharge on that tax. Spain is different: dividends fall into the base imponible del ahorro (savings income base) and are taxed progressively at 19%, 21%, 23%, 27%, and 30% as the amount rises through brackets at €6,000, €50,000, €200,000, and €300,000. The United States has no single dividend tax rate at all — qualified dividends are taxed at 0%, 15%, or 20% depending on your overall taxable income, so this calculator lets you pick the bracket that applies to you rather than computing one automatically.

Withholding at payment time is not always the same as your final tax liability. In South Korea, if your combined interest and dividend income for the year exceeds 20,000,000 KRW, the excess is folded into your other income and taxed at Korea's progressive comprehensive income tax rates, which can run far above 15.4% for high earners — the withholding shown here is just the starting point, not necessarily the final number. Spain works differently but has a similar gap: brokers withhold a flat 19% when the dividend is paid, but your true tax liability follows the progressive savings-income scale described above, and the difference — whether you owe more or get a refund — is settled the following year when you file your Spanish tax return. This calculator shows Spain's final progressive tax as the 'after-tax amount,' not the 19% withheld at payment, since that final figure is what you actually keep.

Dividends from foreign stocks raise a further question: double taxation. If you hold, say, a US stock as a resident of another country, the US typically withholds tax at source, and your home country may also tax that same dividend as part of your worldwide income. Most countries covered here have bilateral tax treaties intended to prevent this — usually through a foreign tax credit, where the tax already paid abroad reduces what you owe at home, or through a reduced treaty withholding rate applied at source instead of the standard domestic rate. The exact relief available depends on the specific treaty between the two countries, your residency status, and how your home country implements the credit, none of which this calculator can determine from a dividend amount alone.

This tool has real limits. It does not model combining this dividend with your other income for the year (beyond the single Korea notice above), it does not apply Germany's tax-free savings allowance (Sparerpauschbetrag, €1,000 for single filers or €2,000 for married couples in 2026), and for the United States it only covers qualified dividends — ordinary (non-qualified) dividends are taxed at regular income tax rates, not the 0/15/20% structure used here. This calculator is for estimation only and is not tax advice; for anything beyond a rough estimate, especially involving a tax treaty or a foreign tax credit, consult a tax professional in the relevant countries.
