If you're an investor, expat, or digital nomad weighing your options between the Netherlands and Italy, understanding each country's capital gains tax regime is essential. A Netherlands Italy capital gains tax comparison reveals two fundamentally different approaches — one taxes presumed returns on wealth, while the other taxes actual realized gains. This distinction can save (or cost) you thousands of euros every year.
In this comprehensive 2025/2026 guide, we'll break down how capital gains are taxed in each country, compare effective rates side by side, walk through practical examples, and help you determine which country has lower capital gains tax for your specific situation.
How Capital Gains Tax Works in the Netherlands (2025/2026)
The Netherlands takes a unique approach to taxing capital gains that often surprises newcomers. Rather than taxing the actual profit you make when selling an asset, the Dutch system taxes a deemed (fictitious) return on your net assets.
The Box 3 System Explained
Dutch personal income tax is divided into three "boxes." Capital gains from personal investments fall under Box 3 (income from savings and investments). Here's how it works for the 2025/2026 tax year:
- Box 3 does not tax your actual capital gains. Instead, the Dutch tax authorities (Belastingdienst) calculate a fictitious return based on the composition of your assets.
- Your net assets (assets minus debts) above a tax-free threshold are subject to tax.
- The tax-free allowance for 2025 is approximately €57,000 per person (€114,000 for tax partners filing jointly).
- A flat tax rate of 36% is applied to the deemed return.
Deemed Return Categories (2025)
The deemed return percentages vary based on asset class:
| Asset Category | Deemed Return Rate (approx.) |
|---|---|
| Savings (bank deposits) | ~0.44% |
| Other investments (stocks, bonds, real estate not being your primary home) | ~6.04% |
| Debts (deductible) | ~2.47% |
The weighted average of these deemed returns, multiplied by 36%, gives you the effective tax owed.
Substantial Interest (Box 2)
If you hold a substantial interest (5% or more) in a company, capital gains are taxed under Box 2 instead:
- Gains up to €67,000: taxed at 24.5%
- Gains above €67,000: taxed at 33%
This is an important distinction for entrepreneurs and business owners.
Key Exemptions and Special Rules
- Primary residence: Your own home is excluded from Box 3 (it falls under Box 1).
- 30% ruling: Qualifying expats under the 30% ruling can opt for partial non-resident taxpayer status, potentially exempting Box 3 assets (though reforms have limited this benefit from 2024 onward).
- Green investments: Certain sustainable investments enjoy a partial exemption in Box 3.

How Capital Gains Tax Works in Italy (2025/2026)
Italy takes a more conventional approach: capital gains are generally taxed on the actual realized profit when you sell an asset. This system is more intuitive but comes with its own complexities.
Standard Capital Gains Tax Rate
For the 2025/2026 tax year, the standard rate on most financial capital gains in Italy is:
- 26% on gains from stocks, bonds (non-government), mutual funds, ETFs, cryptocurrency, and other financial instruments.
- 12.5% on gains from Italian and EU/EEA government bonds and similar instruments.
Qualified Participations
Since 2019, Italy simplified its treatment of qualified participations (significant shareholdings). Capital gains from both qualified and non-qualified participations held by individuals are now subject to the flat 26% substitute tax (imposta sostitutiva).
Real Estate Capital Gains
Capital gains from the sale of real estate in Italy are taxed as follows:
- If sold within 5 years of purchase (and it's not your primary residence): the gain is either added to your ordinary income (taxed at progressive IRPEF rates up to 43%) or taxed at a flat 26% substitute tax at the taxpayer's election.
- If sold after 5 years: generally exempt from capital gains tax (with certain exceptions for properties received via donation).
- Primary residence exemption: No capital gains tax if the property was your main home for the majority of the ownership period.
Italy's Flat Tax Regime for New Residents
Italy offers an attractive €200,000 flat tax regime (regime forfettario per neo-residenti) under Article 24-bis for high-net-worth individuals who transfer their tax residence to Italy. Under this scheme:
- A flat annual tax of €200,000 covers all foreign-sourced income, including foreign capital gains.
- The regime lasts up to 15 years.
- Italian-sourced capital gains remain subject to standard rates.
This can be extraordinarily advantageous for wealthy investors with large international portfolios.

Netherlands vs Italy: Side-by-Side Capital Gains Tax Comparison
Here's a concise comparison table highlighting the key differences for 2025/2026:
| Feature | Netherlands | Italy |
|---|---|---|
| Tax basis | Deemed (fictitious) return on net assets | Actual realized capital gains |
| Standard rate on financial assets | 36% on deemed return (~1.9% effective on total assets) | 26% on actual gains |
| Government bonds | Included in Box 3 deemed return | 12.5% on actual gains |
| Substantial interest / large shareholdings | 24.5%–33% (Box 2) | 26% |
| Real estate (non-primary) | Deemed return in Box 3 | 26% (or IRPEF) if sold within 5 years; exempt after 5 years |
| Primary residence | Exempt from Box 3 | Exempt |
| Tax-free threshold | ~€57,000 per person | No general threshold (but losses can offset gains) |
| Loss offsetting | Limited (losses reduce deemed return base) | Losses can be carried forward for 4 years |
| Crypto gains | Box 3 deemed return | 26% on realized gains |
| Special expat regime | 30% ruling (reduced benefit) | €200,000 flat tax for new residents |
Practical Examples: Which Country Has Lower Capital Gains Tax?
Let's compare real-world scenarios to see where the numbers land.
Example 1: A Stock Portfolio of €200,000 With 10% Annual Gains
In the Netherlands (Box 3):
- Net assets above threshold: €200,000 − €57,000 = €143,000
- Deemed return at ~6.04%: €143,000 × 6.04% = €8,637
- Tax at 36%: €8,637 × 36% = ~€3,109
- This applies regardless of whether you actually made or lost money.
In Italy:
- Actual gain: €200,000 × 10% = €20,000
- Tax at 26%: €20,000 × 26% = €5,200
Winner: Netherlands — in a year of strong returns, the Dutch deemed-return system can be cheaper because it taxes a lower fictitious amount.
Example 2: The Same Portfolio With 0% Actual Gains (Flat Year)
In the Netherlands:
- You still owe ~€3,109 because the deemed return applies regardless.
In Italy:
- No realized gain = €0 tax.
Winner: Italy — overwhelmingly. In a bad or flat year, the Dutch system still taxes you.
Example 3: Selling a €500,000 Investment Property After 6 Years (€80,000 Gain)
In the Netherlands:
- The property's value was part of your Box 3 assets each year. Assuming it was your only asset above the threshold, you paid deemed return tax annually — roughly €5,700–€6,000 per year over 6 years, totaling approximately €34,000–€36,000 in cumulative tax.
In Italy:
- Sold after 5 years: €0 capital gains tax.
Winner: Italy — by a massive margin for long-term real estate investors.
Example 4: Cryptocurrency Gain of €30,000
In the Netherlands:
- Crypto holdings are part of Box 3. On a €100,000 crypto portfolio (above threshold): deemed return tax of approximately €930–€1,100.
In Italy:
- Actual gain of €30,000 × 26% = €7,800.
Winner: Netherlands — for large crypto gains, the deemed-return system is significantly cheaper.
These examples illustrate a critical insight: the Netherlands is more favorable when your actual returns are high, while Italy is more favorable when your returns are low, negative, or when you hold assets long-term (especially real estate).
Double Taxation Agreements and Cross-Border Considerations
If you have financial ties to both countries — or are relocating from one to the other — understanding the Netherlands-Italy double taxation treaty is crucial.
Key Treaty Provisions
- Capital gains from shares: Generally taxed in the country of residence of the seller. If you're a Dutch resident selling Italian stocks, the Netherlands has primary taxing rights (and vice versa).
- Real estate gains: Taxed in the country where the property is located, regardless of your residence. If you're a Dutch resident selling Italian property, Italy taxes the gain — but the Netherlands may also include it in your Box 3 base, with a credit or exemption to avoid double taxation.
- Substantial participations: Special rules may apply under the treaty for gains from selling a significant stake in a company.
Avoiding Double Taxation
Both countries offer mechanisms to prevent being taxed twice:
- Netherlands: Provides a tax credit or exemption for foreign taxes paid on gains that are also subject to Box 3.
- Italy: Offers a foreign tax credit (credito d'imposta) for taxes paid abroad on the same income.
Always verify your specific situation with a cross-border tax advisor, especially during the year of relocation.
Common Mistakes and Misconceptions
Navigating capital gains tax between these two countries involves pitfalls that catch many taxpayers off guard:
Assuming the Netherlands taxes actual gains: The Box 3 deemed-return system is fundamentally different. You can owe tax even in years when your portfolio declines in value.
Forgetting Italy's 5-year real estate rule: Many expats sell Italian property without realizing that gains within 5 years of purchase are fully taxable.
Ignoring the Italian flat tax regime: New residents moving to Italy from the Netherlands can potentially shelter all foreign capital gains under the €200,000 annual flat tax — a powerful planning tool for high-net-worth individuals.
Overlooking crypto obligations: Both countries now actively pursue crypto tax compliance. In the Netherlands, crypto is part of Box 3. In Italy, crypto gains above the €2,000 threshold are taxed at 26%.
Not reporting worldwide assets: Both countries require tax residents to report global assets. The Netherlands uses Box 3; Italy requires the quadro RW (foreign asset monitoring) in the annual tax return.
Misunderstanding the 30% ruling changes: Recent reforms to the Dutch 30% ruling have reduced its scope. Don't assume you'll automatically be exempt from Box 3.

Frequently Asked Questions
Which country has lower capital gains tax — the Netherlands or Italy?
It depends on your actual investment returns. The Netherlands can be cheaper for investors with high actual returns (above the deemed return percentage), while Italy is generally cheaper for those with low returns, losses, or long-term real estate holdings that qualify for exemptions.
Are capital gains tax-free under a certain amount in the Netherlands?
Yes. The Netherlands offers a Box 3 tax-free threshold of approximately €57,000 per person (2025). If your total net investment assets are below this amount, you owe no Box 3 tax.
Does Italy tax capital gains on cryptocurrency?
Yes. As of 2023 reforms (and continuing into 2025/2026), Italy taxes crypto capital gains at 26% on realized gains. There is a de minimis threshold of €2,000 in total crypto gains per year, below which gains may be exempt.
Can I use the Italian flat tax regime if I move from the Netherlands?
Yes, if you qualify. You must not have been an Italian tax resident for at least 9 of the previous 10 years. The regime costs €200,000 per year and covers all foreign-sourced income, including foreign capital gains. Family members can be included for an additional €25,000 each.
How does the Netherlands-Italy tax treaty handle capital gains?
Generally, capital gains from movable property (stocks, bonds) are taxed in the country of the seller's residence. Real estate gains are taxed where the property is located. Both countries offer credits or exemptions to prevent double taxation.
Conclusion: Making the Right Choice for Your Situation
The Netherlands vs Italy capital gains tax comparison reveals no universal winner — the best regime depends entirely on your investment profile, asset types, and financial goals.
