The annual May dilemma
When you file your taxes, Taiwan stock dividend income can be reported as either:
- Combined calculation + 8.5% credit (dividend combined-tax option (股利合併計稅), capped at NT$80,000 per household)
- Separate 28% calculation (dividend separate 28% tax (股利分離課稅 28%), standalone rate)
Someone with NT$200,000 in dividends can lose thousands to tens of thousands by picking wrong. Someone with NT$1,000,000 in dividends can lose tens of thousands to low six figures. This article gives you a practical, executable decision process.
Quick decision table
| Marginal rate | Combined burden (rate − 8.5%) | Separate burden | Pick |
|---|---|---|---|
| 5% | −3.5% (net gain) | 28% | Combined |
| 12% | 3.5% | 28% | Combined |
| 20% | 11.5% | 28% | Combined |
| 30% | 21.5% | 28% | Combined |
| 40% | 31.5% | 28% | Separate |
Bottom line: only those in the 40% bracket should pick separate. Everyone else picks combined.
Why only 40%+ benefits from separate
The 8.5% credit effectively drops your dividend rate by 8.5 percentage points. So:
- Combined effective rate = marginal rate − 8.5%
- Separate is a fixed 28%
Separate beats combined → marginal rate − 8.5% > 28% → marginal rate > 36.5%
In Taiwan's five-tier bracket system, only the 40% tier crosses 36.5%, so only those filers benefit from separate.
How the NT$80,000 cap works
The cap is NT$80,000 per filing household per year. The dividend amount that exhausts it:
80,000 / 8.5% = 941,000
Above NT$940,000 in annual dividends, the additional 8.5% credit is lost on the excess.
Even so, as long as your marginal rate is ≤ 30%, combined still wins. The cap only reduces the benefit; it doesn't flip the direction.
Figuring out your marginal rate
Your marginal rate applies to the last dollar of income.
How to check:
- Calculate net taxable income (income − exemptions − deductions)
- Match against the 2024 brackets:
- 0 – 560K → 5%
- 560K – 1.26M → 12%
- 1.26M – 2.52M → 20%
- 2.52M – 4.72M → 30%
- 4.72M+ → 40%

Concrete examples
Case A: NT$60K/month salary earner (NT$720K/yr)
- After NT$97K exemption + NT$218K salary special deduction + NT$131K standard deduction = NT$446K
- Taxable income NT$274K → marginal 5%
- Dividends NT$150K → combined: 150K × 5% − 150K × 8.5% = net gain of NT$5,250
- Separate: 150K × 28% = pay NT$42,000
- Difference NT$47,250 — obviously pick combined
Case B: NT$150K/month salary earner (NT$1.8M/yr)
- Taxable income ≈ NT$1.25M → marginal 12–20%
- Dividends NT$200K → combined: 200K × 20% − 200K × 8.5% = pay NT$23,000
- Separate: 200K × 28% = pay NT$56,000
- Difference NT$33,000 — pick combined
Case C: Senior executive (NT$6M/yr)
- Taxable income ≈ NT$5.25M → marginal 40%
- Dividends NT$1.5M → combined: 1.5M × 40% − min(127.5K, 80K) = pay NT$520,000
- Separate: 1.5M × 28% = pay NT$420,000
- Difference NT$100,000 — pick separate
Advanced move for married couples
When filing jointly, the dividend method can be chosen independently per spouse:
- Husband on a high salary, 40% marginal, NT$1M dividends → pick separate
- Wife on a lower salary, 12% marginal, NT$500K dividends → pick combined
The online filing system has a separate dividend method toggle for spouses. Make sure to check this option.
Common misconceptions
Misconception 1: Dividends were withheld 21%, so I'm already on separate taxation
Wrong. At payout time, companies may withhold a "payout rate" (typically 0% or 2.11% supplementary NHI), which is a prepayment, not your final tax. You still choose combined or separate when filing.
Misconception 2: Low earners don't need to file
If dividend income + other income exceeds exemptions + deductions, you still need to file. Failing to file means back taxes.
Misconception 3: US stock and Taiwan stock dividends are picked together for combined
Nope. US and other overseas dividends are overseas income under the Alternative Minimum Tax regime — a completely separate tax scheme. See the full overseas income tax guide.
Filing mechanics
When filing online:
- The system auto-populates dividend data from withholding certificates
- Navigate to the "dividend income calculation method" step
- Pick "combined" or "separate" (spouses can pick independently)
- The system calculates both methods in real time so you can compare
- Pick the cheaper one and submit
Tax-saving tactics
Control total annual dividends
If your marginal rate will jump to 40% this year, options include:
- Spreading dividend receipts: some ETFs offer monthly vs quarterly distributions (though most don't let you choose)
- Selling before ex-dividend: sell a high-yield ETF before ex-date, buy back after (watch out for transaction costs and price slippage)
Use family exemptions
Family members with no income (school-age children, retired parents) can hold stock in their own name, using their NT$97K exemption fully. But watch out for dependent income thresholds — if their assets exceed limits, dependency claims may fail.
Dividend ETFs vs growth ETFs
If your marginal rate is high, reducing dividend exposure (picking growth-focused ETFs like VT, VTI) lowers your tax base. But there are other considerations (see the high-yield ETF myth).
