Want to invest and receive dividends, but feel completely confused about “dividend income tax”? How is dividend income tax calculated? When tax season arrives, how should you file to legally reduce your tax burden? This article will take you through the latest 2025 dividend tax rules, from the fundamentals and calculation methods to practical filing tips, so you can master the key details of dividend tax filing with ease and stop missing any tax-saving opportunities!
In Taiwan, when you invest in listed and OTC companies and receive dividends (commonly referred to as “dividend payouts”), this income must be reported for income tax purposes. This is what’s known as “dividend income tax”. Simply put, dividends are a return distributed to shareholders from a company’s profits, and the government taxes this income to maintain tax fairness.
Understanding how dividend income tax is calculated and reported is crucial for every investor. This not only affects how much net investment profit you ultimately keep, but also determines whether you can legally reduce taxes and avoid unnecessary tax burdens.
Taiwan’s dividend income tax mainly has two taxation methods: comprehensive income tax “combined taxation” and a single-rate “separate taxation”. The option you choose will have a significant impact on your tax burden. Understanding the differences and applicable scenarios of these two methods is the first step to paying dividend taxes wisely.
Which method is more suitable for you often depends on the level of your net comprehensive income. By choosing the right filing method, you may be able to maximize your dividend returns. Interested in tax issues related to other financial products?
“Dividend income tax calculation” is one of the aspects investors care about most. A deeper understanding of the details of combined taxation and separate taxation can help you make the most favorable choice when filing your taxes.
When you choose to include dividend income in your comprehensive income tax filing, the calculation method is relatively more complex. However, for low- to middle-income earners, it is often the more favorable option. The key to combined taxation lies in the “Dividend Tax Credit”.
Calculation Process:
Example:
Assume that Xiao Ming’s net comprehensive income for tax year 2025 is 500,000 (applicable tax rate: 5%), which includes dividend income of TWD 100,000. Xiao Ming chooses combined taxation.
This example clearly shows how the dividend tax credit helps reduce the overall tax burden.
Separate taxation means that dividend income is not combined with other comprehensive income. Instead, it is taxed separately at a flat rate of 28%. For high-income earners, separate taxation is often a more attractive option because it can prevent dividend income from pushing the taxpayer into a higher comprehensive income tax bracket.
Applicable Scenarios:
When your net comprehensive income already falls into a higher tax bracket (for example, 20% or above), and your dividend income is relatively large, choosing separate taxation may be more cost-effective. Although there is no 8.5% dividend tax credit, the fixed 28% rate may be lower than your marginal tax rate under comprehensive income taxation.
Example:
Assume that Xiao Hua’s net comprehensive income for tax year 2025 is TWD 3,000,000 (applicable tax rate: 30%), which includes dividend income of TWD 500,000. Xiao Hua chooses separate taxation.
If Xiao Hua chose combined taxation, the dividend income would be included in the total comprehensive income of 3,000,000 and could push the applicable tax rate even higher. Therefore, for high-income earners, separate taxation can effectively lock in the tax rate on dividend income and avoid an excessively high marginal tax rate.

For “high-dividend investors” who rely on dividend income, in addition to dividend income tax, you should also pay close attention to the rules on the “Second-Generation NHI supplementary premium”. Under the National Health Insurance Act, dividends paid in a single payment that reach a certain threshold will be subject to a supplementary premium.
Currently, if a single dividend payment exceeds TWD 20,000, a 2.11% supplementary premium must be paid. This fee is withheld by the dividend-paying company at the time of payment, so the amount investors receive is usually the net amount after the supplementary premium has been deducted. Although this is not part of income tax, it is still an important cost that affects your actual investment returns, and you should factor it into your dividend income planning.
Mastering the correct process and timeline for “dividend tax filing” is key to staying compliant. Below is a summary of the filing steps, common issues, and the latest reminders for 2025.
Dividend income is generally filed together with your comprehensive income tax return during May 1 to May 31 each year. When filing, you can use the following methods:
No matter which method you choose, be sure to complete both filing and payment within the deadline to avoid late payment fees or penalties. If you have more questions about the details of online tax filing, this guide may help: Online Tax Filing Tutorial.
For beginners who are new to “dividend income tax” and stock investing, it’s common to have questions about paying tax on dividends. We’ve compiled several frequently asked questions to help you avoid common tax filing mistakes.
Tax rules may undergo minor adjustments each year, so it is important to stay updated on the latest “dividend tax filing” regulations. While the 2025 dividend tax framework largely continues from previous years, you should still pay attention to the following points:
In addition to understanding how “dividend income tax calculations” work, it is even more important to master legal “dividend tax-saving strategies” to maximize your investment returns.
The key to this strategy is to carefully run the numbers each year before filing taxes, based on your net consolidated income and dividend income amount, and compare the tax payable under “combined taxation” versus “separate taxation”. For lower-income investors, because the applicable tax bracket is lower, combined taxation together with the 8.5% dividend tax credit (capped at NTD 80,000) is usually more favorable. Conversely, for high-income earners, if the consolidated income is already subject to higher tax rates, choosing the 28% separate taxation can effectively reduce the impact of a higher marginal tax rate.
Practical Tips:
In addition to choosing a taxation method, there are several other strategies that can help reduce your “dividend tax payment” burden:
A: Not necessarily. In Taiwan, dividend income does not have an absolute “tax-free threshold”. Instead, it depends on your total consolidated income tax situation, household circumstances, and the taxation method you choose. For taxpayers who choose “combined taxation”, dividend income is included in total consolidated income and is eligible for an 8.5% tax credit, capped at NTD 80,000. This means that if your dividend income multiplied by 8.5% is enough to fully offset or reduce your tax payable, you may effectively achieve a “tax-free” outcome. For individuals with very low income or those who do not need to pay consolidated income tax, even if they have dividend income, they may still end up paying no tax due to the credit. In short, the effective tax-free threshold varies depending on factors such as individual income, exemptions, and deductions.
A: This depends entirely on your total consolidated income. In general:
The safest approach is to use the tax filing software or online trial calculation system provided by the Ministry of Finance when filing your taxes, enter both methods separately, and compare which one results in a lower tax payable.
A: Yes. Under certain circumstances, dividend income tax can be credited. The main credit item is the 8.5% dividend tax credit calculated based on the “total amount of dividends and earnings”, but it is capped at NTD 80,000. This credit is only available to taxpayers who choose “combined taxation.” For example, if your total dividends and earnings amount to NTD 1,000,000, the credit would be NTD 1,000,000 × 8.5% = NTD 85,000. However, because the cap is NTD 80,000, the actual credit you can claim is NTD 80,000. This NTD 80,000 is deducted from the consolidated income tax payable calculated for you. As for other credit items, such as investment losses, they generally cannot be directly used to offset dividend income tax. However, investment-related expenses may, under certain conditions, be deductible when calculating income.
A: Yes. Taiwan’s tax law provides that if a resident has income sourced outside the Republic of China, it should be included in the basic income amount. This means that if you are a Taiwan tax resident and receive dividends (dividend income) from overseas stocks or ETFs, this overseas dividend income must be reported as part of the “basic income amount” and is subject to the “minimum tax burden system”. Although this income is not directly included in the consolidated income tax calculation, if your basic income amount exceeds the prescribed exemption amount (currently NTD 6.7 million), you must pay a 20% minimum tax differential. Therefore, even for overseas investments, dividend income should be included in your Taiwan tax planning considerations.
A: Even if your dividend income is not large, it is still recommended that you pay some attention to it. For small investors, because the consolidated income tax rate usually falls within the 5% or 12% brackets, choosing “combined taxation” and making good use of the 8.5% dividend tax credit may very likely result in effectively no dividend income tax payable, and may even produce a tax refund. As long as you use the Ministry of Finance tax filing software or the online system to automatically import your data, the system will automatically calculate it for you, which is very convenient. Understanding these rules not only ensures legal compliance, but also helps you avoid missing any tax-saving opportunities, so that every bit of your investment returns can stay in your pocket.
