How Is Dividend Income Tax Calculated? Combined vs. Separate Taxation in Taiwan
Dividend income received from a company is generally included in Taiwan's individual income-tax filing. Taiwan resident individuals can choose one of two methods for household dividends: combined taxation with a dividend tax credit, or separate taxation at a flat 28% rate. The better method depends on the household's other income, deductions, and tax bracket—not simply on the size of one dividend payment.
The practical approach is to check the prefilled data in the Ministry of Finance online filing system and compare its calculations before filing. The system can select the more favorable dividend-tax method. This article focuses on common domestic dividend income for Taiwan residents; overseas income, non-resident status, company shareholders, and complex tax situations should be checked with the tax authority or a qualified professional.

What is dividend income tax?
Dividends are distributions of a company's earnings to shareholders. Cash dividends and stock dividends are basic distribution formats; see What Are Dividends? for those concepts. This article addresses how domestic dividend income is treated when filing individual income tax.
Keep three topics separate: dividend income tax is part of annual income-tax filing; Taiwan's supplementary health-insurance premium is a separate system that may be withheld by the payer; and ex-dividend price movements concern investment performance, not a tax exemption. For the supplementary premium, see the dividend supplementary-premium guide.
Two ways to tax dividends
Combined taxation with an 8.5% tax credit
Under combined taxation, household dividends are included in total consolidated income. A tax credit is calculated at 8.5% of household dividends and earnings, capped at NT$80,000 per household. The final result still depends on the household's other income, exemptions, deductions, and other credits.
Separate taxation at 28%
Under separate taxation, household dividends and earnings are excluded from consolidated income and taxed at a flat 28%. That amount is then added to the tax calculated on other income. A 28% rate is not automatically better simply because dividends are large; the complete household result must be compared.
Quick answer: which method should I choose?
Use this first-pass rule for common domestic-dividend cases. If household income including dividends does not enter the top 40% bracket, and annual household dividends and earnings are roughly below NT$941,000, combined taxation is generally the first choice. If the household's other income is already in the top 40% bracket, separate taxation at 28% is generally the first choice.
The NT$941,000 figure is an approximation: it is the NT$80,000 tax-credit cap divided by 8.5%. Below that level, the 8.5% credit can generally be fully used. If dividends push income into the top bracket, exceed that amount, or the household has overseas income, minimum-tax issues, or other special items, use the online filing system's full calculation instead of a shortcut.
How to file dividend income tax
- Confirm the filing household and year. The comparison applies to household dividends and earnings, so check the taxpayer, spouse, and dependents.
- Check payer and income data. Compare company names, amounts, and tax year with the information prefilled in the filing system.
- Compare both methods in the online system. Make sure income, dependents, deductions, and tax credits are correct before relying on the result.
- Review health-insurance and income-tax records separately. A supplementary-premium deduction does not replace annual income-tax filing.
- Keep the filing receipt and supporting records. If you find an error during the filing period, update the online filing and resubmit.
FAQ
Is the 8.5% amount a tax I need to pay?
No. It is the percentage used to calculate a tax credit under combined taxation, subject to a NT$80,000 household cap. The full income-tax result still depends on the household calculation.
What does the 28% rate mean?
It is the flat rate for household dividends and earnings when separate taxation is selected. It is added to the tax on other income.
Does paying the supplementary health-insurance premium settle my dividend income tax?
No. The supplementary premium and income tax are separate systems.
Do large dividends always mean I should choose 28%?
No. A household already in the top 40% bracket will often favor separate taxation, but amounts above the tax-credit cap and any cross-bracket effects should be checked in the filing system.
Can I apply this directly to overseas dividends?
Not necessarily. Overseas income can have separate source, minimum-tax, and filing considerations. Confirm the applicable rules before filing.
Conclusion
Separate income tax, supplementary health-insurance premiums, and investment performance into different decisions. Use the filing system to compare combined and separate taxation, check supplementary premiums under their own rules, and evaluate an investment based on its risks and long-term objectives rather than the cash dividend alone.
