Finland taxes capital income - dividends and capital gains combined, from any source including US stocks - at 30% on the first €30,000 in a year, and 34% on everything above that threshold. Unlike a progressive wage-income scale with many brackets, this is a simple two-tier system, but the €30,000 threshold combines dividends and capital gains into a single pool - meaning an investor who’s already used up the 30% bracket with dividend income pushes any further capital gain straight into the higher 34% rate, the same combined-threshold mechanic that trips up investors in a few other countries covered in this series.
This guide covers that two-tier structure and the treaty’s standard 15% dividend withholding rate.
The 30%/34% Split: Dividends and Gains Share One Threshold
Finland’s pääomatulovero (capital income tax) applies uniformly to dividends, capital gains, interest, and rental income - all combined into a single “capital income” category for tax purposes, not assessed separately by income type.
The two-tier rate:
- 30% on capital income up to €30,000 in a tax year
- 34% on capital income above €30,000
Worked example: a Finnish investor with €22,000 in US dividend income for the year and a separate €15,000 capital gain from selling a US stock position has €37,000 in combined capital income. The first €30,000 (all of the dividend income, plus €8,000 of the gain) is taxed at 30%; the remaining €7,000 of the gain is taxed at 34%. Realizing that gain in a different year, when dividend income is lower, would keep more of it under the 30% threshold - the kind of timing consideration this combined-threshold structure rewards.
Foreign tax credit: the 15% US withholding on dividends (see below) is creditable against the Finnish capital income tax due on that same dividend, capped at the Finnish tax otherwise applicable.
Finland’s 15% Dividend Rate
| Income Type | Default US Rate | Treaty Rate (Portfolio) |
|---|---|---|
| Dividends | 30% | 15% |
| Capital gains (securities) | Generally not US-taxable for non-residents | Residence country only |

Your broker needs Form W-8BEN before it will apply 15%. The form is the mechanism; the treaty alone does nothing for you.
Worked example - a $2,500 US dividend, investor in the 30% Finnish bracket for the year:
- US withholding at 15% (treaty rate, W-8BEN on file): $375
- Finnish capital income tax at 30% on the gross $2,500: $750
- Foreign tax credit for the US withholding already paid: -$375
- Net Finnish tax owed: $375
- Total: $750. Finland’s 30% is the number that ends up mattering; the US half is simply collected first and credited back.
Where the EUR 30,000 Threshold Actually Bites
Finland pools dividends and capital gains into one bucket before applying the two-tier rate, and that pooling is what catches people out. Consider an investor with EUR 20,000 of US dividends who then realises a EUR 25,000 gain in the same year.
- The dividends fill EUR 20,000 of the 30% band
- Only EUR 10,000 of the gain fits in the remaining 30% space
- The other EUR 15,000 is taxed at 34%
| Amount | Rate | Tax | |
|---|---|---|---|
| Dividends | EUR 20,000 | 30% | EUR 6,000 |
| Gain, within threshold | EUR 10,000 | 30% | EUR 3,000 |
| Gain, above threshold | EUR 15,000 | 34% | EUR 5,100 |
| Total | EUR 45,000 | EUR 14,100 |
Split that same gain across two tax years and the EUR 15,000 would have been taxed at 30% instead of 34% - a EUR 600 difference from timing alone.
On the US side, the treaty holds dividend withholding to 15% rather than 30% once W-8BEN is filed, and that 15% credits against the Finnish liability on the same income rather than stacking on it.

A Finnish Investor’s Checklist
What a Finnish investor needs to have covered:
- Confirm W-8BEN is on file with your broker; verify 15%, not 30%, on dividend statements
- Renew W-8BEN before the three-year expiry
- Track combined dividends and capital gains against the €30,000 annual threshold - both count toward the same figure, and exceeding it pushes the excess into the 34% bracket regardless of which income type crosses the line
- Consider timing large capital gain realizations around years with lower dividend income to maximize how much stays in the 30% bracket
- Claim the foreign tax credit for the 15% US withholding against Finnish capital income tax on the same dividend
- Re-check account-opening requirements with the broker directly before you apply
Finland, in a Paragraph
The treaty rate is standard - 15% on dividends, claimed with W-8BEN, credited cleanly against Finland’s 30% base capital income rate. The detail worth tracking deliberately is the combined €30,000 threshold: dividends and capital gains share one pool, not separate allowances, so an investor who only checks dividend income against the threshold can be surprised when a capital gain later in the year pushes the combined total into the 34% bracket - the same trap that catches investors in a few other countries in this series with similarly combined thresholds.
This lays out investing from Finland generally; nothing in it is advice. Everything quoted on rates traces to the US-Finland Income Tax Convention. Finland’s capital income tax rates and the EUR 30,000 threshold are set by Finnish law and can change annually. Have a qualified Finnish tax advisor check this against your own holdings.
