If you're an investor, expat, or business owner with financial ties to both sides of the Atlantic, understanding the United States Italy capital gains tax comparison is essential for minimizing your tax burden in 2025/2026. Whether you're selling stocks in New York, disposing of property in Rome, or simply planning your next cross-border investment, knowing which country has lower capital gains tax can save you thousands of dollars — or euros — each year.

In this comprehensive guide, we'll compare capital gains tax rates, rules, and exemptions in the United States and Italy, walk through practical examples, and highlight the tax treaty provisions that prevent you from being taxed twice on the same gain. Let's dive in.

How Capital Gains Tax Works: A Quick Overview

Before we compare the two countries, let's establish what capital gains tax actually is. A capital gain is the profit you realize when you sell an asset — such as stocks, bonds, real estate, or cryptocurrency — for more than you originally paid for it. Most countries tax these gains, but the rates, holding-period distinctions, and exemptions vary dramatically.

The two critical variables in any capital gains tax system are:

  • Short-term vs. long-term classification — how long you held the asset before selling
  • Tax rate structure — whether gains are taxed at a flat rate or on a progressive scale

Both the United States and Italy tax capital gains, but they use fundamentally different approaches. Understanding these differences is the first step toward smarter tax planning.

United States Capital Gains Tax Rates for 2025/2026

The U.S. federal capital gains tax system distinguishes sharply between short-term and long-term gains, with dramatically different tax consequences depending on your holding period.

Short-Term Capital Gains

Assets held for one year or less before sale generate short-term capital gains. These are taxed as ordinary income, meaning they're subject to the standard federal income tax brackets. For 2025, the top marginal rate is 37%.

Taxable Income (Single Filer) Federal Tax Rate
Up to $11,925 10%
$11,926 – $48,475 12%
$48,476 – $103,350 22%
$103,351 – $197,300 24%
$197,301 – $250,525 32%
$250,526 – $626,350 35%
Over $626,350 37%

Long-Term Capital Gains

Assets held for more than one year qualify for preferential long-term capital gains rates:

Taxable Income (Single Filer) Long-Term CG Rate
Up to $48,350 0%
$48,351 – $533,400 15%
Over $533,400 20%

Net Investment Income Tax (NIIT)

High-income taxpayers in the U.S. also face an additional 3.8% Net Investment Income Tax (NIIT) on capital gains if their modified adjusted gross income exceeds $200,000 (single) or $250,000 (married filing jointly). This brings the effective top federal rate on long-term gains to 23.8%.

State-Level Capital Gains Taxes

Don't forget that most U.S. states impose their own income tax on capital gains. States like California add up to 13.3%, while states like Florida, Texas, and Nevada have no state income tax. The combined federal-plus-state rate can therefore range from 0% to over 37% depending on your state of residence and income level.

Italy Capital Gains Tax Rates for 2025/2026

Italy takes a notably different approach. Rather than distinguishing between short-term and long-term holding periods for most financial assets, Italy generally applies a flat substitute tax on capital gains.

Financial Assets (Stocks, Bonds, Funds)

Most capital gains from the sale of financial instruments — including shares, bonds, mutual funds, ETFs, and derivatives — are subject to a flat 26% substitute tax (imposta sostitutiva). This rate applies regardless of the holding period.

There is one important exception: gains on Italian government bonds (and bonds from EU/EEA white-list countries) are taxed at a reduced flat rate of 12.5%.

Qualified Participations

For individuals holding qualified participations (generally more than 20% of voting rights or 25% of capital in listed companies, or 2%/5% respectively), gains were historically subject to progressive IRPEF taxation. However, since 2019, Italy has unified the treatment: virtually all financial capital gains for individuals are now taxed at the 26% flat rate.

Real Estate Capital Gains

Italy's treatment of real estate gains offers a significant planning opportunity:

  • Properties held for less than 5 years: Gains are taxable either at the 26% flat substitute tax rate or included in ordinary IRPEF income (progressive rates up to 43%) — the taxpayer can choose the more favorable option.
  • Properties held for more than 5 years: Gains are completely exempt from capital gains tax (with exceptions for properties acquired through donation within the prior 5 years).
  • Primary residence exemption: Gains from the sale of a property used as the taxpayer's primary residence (prima casa) for the majority of the holding period are fully exempt, regardless of the holding period.

Italy's IRPEF Progressive Rates (for Reference)

When gains are subject to ordinary taxation, Italy's 2025 IRPEF brackets apply:

Taxable Income IRPEF Rate
Up to €28,000 23%
€28,001 – €50,000 35%
Over €50,000 43%

Regional and municipal surcharges of approximately 1.5% – 3.5% can push the effective top rate to around 47%.

United States vs Italy: Side-by-Side Capital Gains Tax Comparison

Here's a concise comparison table summarizing the key differences:

Feature United States Italy
Short-term gains rate 10% – 37% (ordinary income rates) 26% flat (financial assets)
Long-term gains rate 0% / 15% / 20% + 3.8% NIIT 26% flat (financial assets)
Holding period threshold 1 year Generally N/A for financial assets
Top effective federal rate 23.8% (federal only) 26% (substitute tax)
Real estate exemption $250K/$500K primary residence Full exemption after 5 years
Government bond gains Taxed like other gains 12.5% reduced rate
State/local taxes 0% – 13.3% additional ~1.5% – 3.5% surcharges (if IRPEF)
Cryptocurrency Same as other capital assets 26% flat (above €2,000 threshold)

Which Country Has Lower Capital Gains Tax?

The answer depends on your income level, asset type, and holding period:

  • For low-to-moderate income earners with long-term gains: The United States is clearly more favorable. The 0% bracket on long-term gains (up to $48,350 for single filers) and the 15% rate for most middle-class investors beat Italy's flat 26%.
  • For high-income earners with short-term gains: Italy may be cheaper. A U.S. taxpayer in the 37% bracket plus state taxes could face a combined rate of 45%+, while Italy's flat 26% applies regardless of income or holding period.
  • For real estate investors: Italy offers a powerful exemption after 5 years of ownership. The U.S. primary residence exclusion ($250K/$500K) is generous but doesn't apply to investment properties, which are taxed at full capital gains rates (though 1031 exchanges allow deferrals).
  • For government bond investors: Italy's 12.5% rate is far more favorable than U.S. rates on bond gains.

Practical Examples: Calculating Your Capital Gains Tax

Let's make this comparison concrete with two real-world scenarios.

Example 1: Selling $100,000 in Stock Gains (Long-Term)

Scenario: You're a single filer earning $80,000 in wages and realizing $100,000 in long-term stock gains.

In the United States:

  • Your total income is $180,000
  • The $100,000 in long-term gains is taxed at 15% (you're below the 20% threshold)
  • Federal capital gains tax: $15,000
  • No NIIT applies (MAGI under $200,000)
  • State tax (e.g., New York): approximately $6,500
  • Total: ~$21,500

In Italy:

  • The $100,000 (~€92,000) gain is taxed at the flat 26% rate
  • Tax owed: €23,920 (~$26,000)
  • No additional surcharges on substitute-tax gains
  • Total: ~$26,000

Winner: United States — saving approximately $4,500 in this scenario. In a zero-income-tax state like Florida, the U.S. advantage grows to about $11,000.

Example 2: Selling a Rental Property After 6 Years With €200,000 Gain

Scenario: You sell an investment property (not your primary residence) held for 6 years, realizing a €200,000 gain.

In Italy:

  • Property held for more than 5 years: €0 in capital gains tax
  • Total: €0

In the United States:

  • The gain is long-term, taxed at 15% or 20% depending on income
  • Assuming the 15% bracket: $30,000 federal tax
  • Plus depreciation recapture at 25% on prior deductions
  • Plus potential state taxes and NIIT
  • Total: $35,000–$50,000+

Winner: Italy — by a wide margin for long-held real estate.

The U.S.–Italy Tax Treaty and Avoiding Double Taxation

If you have tax obligations in both countries — for example, you're a U.S. citizen living in Italy, or an Italian resident with U.S. investments — the U.S.–Italy Double Taxation Treaty (signed in 1999) is critical to understand.

Key Treaty Provisions for Capital Gains

  1. Shares and securities: Generally taxable only in the seller's country of residence, unless the gains relate to a permanent establishment in the other country.
  2. Real property: Gains from the sale of real estate may be taxed in the country where the property is located, regardless of the seller's residence.
  3. Foreign Tax Credit: Both countries allow taxpayers to claim a credit for taxes paid to the other country, preventing the same gain from being taxed twice.

Common Pitfalls for Dual Taxpayers

  • U.S. citizens in Italy: The U.S. taxes its citizens on worldwide income regardless of where they live. You'll file returns in both countries and claim Italy's 26% tax as a foreign tax credit on your U.S. return. Since 26% often exceeds the U.S. rate on long-term gains, you may have excess foreign tax credits that carry forward.
  • Italian residents with U.S. investments: U.S. withholding on dividends is generally reduced to 15% under the treaty. Capital gains on U.S. stocks are typically taxed only in Italy at 26%.
  • PFIC rules: U.S. persons holding Italian-domiciled mutual funds may face punitive Passive Foreign Investment Company (PFIC) taxation. This is one of the most common and costly mistakes for Americans living in Italy.

Cryptocurrency, NFTs, and Digital Assets

Digital assets have become a major source of capital gains, and the two countries handle them differently.

United States

The IRS treats cryptocurrency, NFTs, and digital tokens as property. The same short-term/long-term distinction applies:

  • Held ≤ 1 year: taxed at ordinary income rates (up to 37%)
  • Held > 1 year: taxed at 0%/15%/20% + potential 3.8% NIIT

Starting in 2025, centralized exchanges must issue Form 1099-DA for digital asset transactions, increasing IRS enforcement.

Italy

Italy taxes crypto gains at 26% flat, consistent with other financial assets. However, Italy provides a €2,000 annual de minimis threshold — gains below this amount in a tax year are not taxed. Additionally, Italy introduced rules requiring taxpayers to declare crypto holdings on their annual return and pay a 0.2% wealth tax (IVAFE) on the value of digital assets held.

Advantage: For small-scale crypto traders, Italy's €2,000 exemption is beneficial. For large gains held long-term, the U.S. 15% or 20% rate beats Italy's 26%.

Frequently Asked Questions

Is capital gains tax higher in the United States or Italy?

It depends on the situation. For long-term financial asset gains, the U.S. is generally cheaper (0%–23.8% vs. Italy's flat 26%). For short-term gains, Italy's 26% is often lower than U.S. rates of up to 37%+ state taxes. For real estate held over 5 years, Italy offers a complete exemption that the U.S. cannot match.

Do U.S. citizens living in Italy pay capital gains tax twice?

Not exactly. While U.S. citizens must report worldwide income to the IRS regardless of residency, the U.S.–Italy tax treaty and the Foreign Tax Credit mechanism prevent true double taxation. You'll pay the higher of the two countries' rates, not both.

Can I avoid capital gains tax by moving from the U.S. to Italy (or vice versa)?

Potentially, but with major caveats. U.S. citizens remain subject to U.S. taxation regardless of residence. Renouncing U.S. citizenship triggers an exit tax (mark-to-market on unrealized gains). Italy's more favorable real estate rules, however, can benefit non-U.S.-citizen investors who establish Italian residency before selling.

How does Italy's flat tax regime for new residents affect capital gains?

Italy's €200,000 flat tax option for new residents (the regime forfettario for high-net-worth individuals) covers foreign-source income only. Gains on Italian assets remain subject to normal Italian taxation. U.S.-sourced capital gains for qualifying new Italian residents may be covered under this regime, making it extremely attractive for wealthy individuals relocating from the U.S.

Conclusion: Key Takeaways for 2025/2026

Choosing between the United States and Italy for tax efficiency on capital gains is not a one-size-fits-all decision. Here are the key takeaways:

  1. Long-term stock investors generally pay less in the U.S. thanks to the 0%/15%/20% tiered system, especially if they reside in a zero-income-tax state.
  2. Short-term traders may find Italy's flat 26% more predictable and often cheaper than U.S. ordinary income rates plus state taxes.
  3. Real estate investors should seriously consider Italy's 5-year exemption, which has no equivalent in the U.S. system.
  4. Government bond investors benefit from Italy's reduced 12.5% rate.
  5. Dual taxpayers should understand the U.S.–Italy tax treaty and use foreign tax credits strategically to avoid double taxation.
  6. Crypto investors should note Italy's €2,000 exemption threshold and the U.S.'s more favorable long-term rates for larger gains.
