Comprehensive, Data-Driven, and Unfiltered
San Marino, the world’s oldest surviving republic, is a microstate enclaved within Italy. With a population of just 33,600 (2026 estimate) and a GDP of €1.7 billion, it offers a low-tax environment compared to most of Europe. However, its tax system is complex, opaque, and heavily negotiated—especially for expats.
This guide covers:
✅ Income tax rates (progressive, flat, and special regimes)
✅ Property tax (IMU, registration fees, and wealth taxes)
✅ Capital gains tax (real estate, stocks, and crypto)
✅ Double taxation treaties (Italy, EU, and beyond)
✅ Tax residency rules (183-day rule, economic ties, and loopholes)
✅ Crypto taxation (new 2025 reforms)
✅ Downsides & traps (bureaucracy, blacklists, and exit taxes)
1. Income Tax in San Marino (2026)
San Marino has three income tax systems:
- Progressive IRPEF (for employees & self-employed)
- Flat tax (17%) (for high-net-worth individuals & retirees)
- Corporate tax (17%) (for businesses)
1.1 Progressive Income Tax (IRPEF) – For Employees & Self-Employed
San Marino’s IRPEF (Imposta sul Reddito delle Persone Fisiche) is progressive but less aggressive than Italy’s.
| Annual Income (EUR) | Tax Rate | Tax Due (EUR) |
|---|---|---|
| 0 – 15,000 | 9% | 0 – 1,350 |
| 15,001 – 28,000 | 12% | 1,350 + (Income – 15,000) × 12% |
| 28,001 – 55,000 | 18% | 2,910 + (Income – 28,000) × 18% |
| 55,001 – 80,000 | 23% | 7,770 + (Income – 55,000) × 23% |
| 80,001 – 150,000 | 28% | 13,620 + (Income – 80,000) × 28% |
| 150,001+ | 35% | 33,220 + (Income – 150,000) × 35% |
Key Notes:

- High social security for self-employed (24% vs. ~15% in Italy).
1.2 Flat Tax (17%) – For High-Net-Worth Individuals (HNWIs) & Retirees

1.3 Corporate Tax (IRES) – 17% Flat Rate
San Marino’s corporate tax (IRES) is 17%, one of the lowest in Europe.
| Tax Type | Rate | Notes |
|---|---|---|

2. Property Tax in San Marino (2026)
San Marino has no annual property tax (unlike Italy’s IMU), but transaction costs are high.
2.1 Property Purchase Costs

|---|---|---|
| Registration tax | 3% | On purchase price (reduced to 2% for first home) |
| Notary fees | 1-2% | Negotiable (higher for foreign buyers) |
| Agent fees | 3-5% | Paid by buyer (unlike Italy, where seller pays) |
| Stamp duty | €168 | Fixed fee |

Example:

| Commercial rent | 17% | After 25% deduction (effective rate: 12.75%) |
| Short-term rent | 24% | No deductions (like Airbnb) |
Example:
- €2,000/month residential rent → €24,000/year

- No inflation adjustment (unlike Switzerland).
4. Double Taxation Treaties (2026)
San Marino has limited tax treaties—only 10 in force (vs. Italy’s 100+).
| Country | Dividends | Interest | Royalties | Capital Gains | Notes |
|---|---|---|---|---|---|
| Italy | 15% | 10% | 5% | 0% (if >5 years) | Most important treaty |

Missing Treaties (Big Problem for Expats):
❌ No treaty with the US (unlike Italy, which has one).
❌ No treaty with the UK (post-Brexit).
❌ No treaty with Germany, France, or Spain.
Downside:
- US expats face double taxation (San Marino taxes worldwide income, and the US does too).
- No relief for foreign dividends/interest (unlike Italy’s 1.20% substitute tax).
5. Tax Residency Rules (2026)
San Marino uses three tests to determine tax residency:
5.1 The 183-Day Rule
- If you spend ≥183 days/year in San Marino, you’re tax resident.
- Partial days count (arrival/departure days included).
5.2 Economic Ties (Centre of Vital Interests)
- If your family, business, or assets are in San Marino, you’re tax resident even if you spend <183 days.
- Example: If you own a home in San Marino and your spouse lives there, you’re tax resident.
5.3 Domicile (Permanent Home)
- If you have a permanent home in San Marino (even if you don’t live there), you’re tax resident.
Downside:
- No "non-dom" regime (unlike Italy’s €100,000 flat tax for HNWIs).
- Exit tax if you leave within 5 years of taking the 17% flat tax.
6. Crypto Taxation in San Marino (2026)
San Marino introduced crypto tax rules in 2025 (Law No. 185/2024).
6.1 Crypto Tax Rates
| Transaction Type | Tax Rate | Notes |
|---|---|---|
| Capital gains (short-term) | 17% | Held <12 months |
| Capital gains (long-term) | 0% | Held >12 months |
| Mining/staking rewards | 17% | Taxed as income |
| Airdrops | 17% | Taxed as income |
| DeFi yields | 17% | Taxed as income |
| NFT sales | 17% | No exemption |
Downside:
- No loss offset (unlike Germany, where crypto losses can offset gains).
- No "bed & breakfast" rule (unlike the UK, where you can sell and rebuy within 30 days to reset cost basis).
6.2 Crypto Reporting Requirements
- All crypto transactions must be reported in the annual tax return (Modello Unico).
- Exchanges must report to San Marino tax authorities (similar to DAC8 in the EU).
- Failure to report → Fines up to 150% of tax due.
Example:
- Bought Bitcoin at €10,000, sold at €50,000 after 6 months → €40,000 gain × 17% = €6,800 tax.
- If held >12 months → 0% tax.
7. Downsides & Traps for Expats (2026)
San Marino is not a tax paradise—it has hidden costs and risks.
7.1 EU Blacklist (Since 2022)
- San Marino is on the EU’s list of non-cooperative jurisdictions.
- Banks may refuse transfers from San Marino accounts.
- Higher scrutiny from tax authorities (Italy, Germany, etc.).
7.2 No US Tax Treaty
- US expats face double taxation (San Marino taxes worldwide income, and the US does too).
- No FATCA relief (unlike Switzerland or Singapore).
7.3 High Cost of Living
| Expense | San Marino (EUR) | Italy (EUR) | Difference |
|---|---|---|---|
| 1-bed apartment (rent) | €1,200/month | €800/month | +50% |
| Groceries (monthly) | €400 | €300 | +33% |
| Restaurant meal | €25 | €15 | +66% |
| Private health insurance | €200/month | €100/month | +100% |
7.4 Bureaucracy & Language Barrier
- All documents must be in Italian.
- No English-speaking tax advisors (unlike Malta or Cyprus).
- Slow processing times (6+ months for residency permits).
7.5 Exit Tax (If You Leave Early)
- If you take the 17% flat tax and leave within 5 years, you must repay the tax savings.
- Example: If you saved €50,000 in taxes and leave after 3 years, you owe €20,000 back.

10. Alternatives to San Marino (2026)
If San Marino’s blacklist status, bureaucracy, or lack of treaties is a dealbreaker, consider:
| Country | Income Tax | Capital Gains | Crypto Tax | US Treaty? | EU Blacklisted? |
|---|---|---|---|---|---|
| Portugal | 20-48% | 28% | 28% | ✅ | ❌ |
| Malta | 0-35% | 15% | 0-35% | ✅ | ❌ |

Final Verdict: Is San Marino Worth It?
✅ Yes, if:
- You’re Italian (easy residency, good treaty).
- You earn €80K+/year (17% flat tax).
- You hold crypto >12 months (0% long-term gains).
- You want EU proximity without EU taxes.
❌ No, if:
- You’re American (double taxation, no treaty).
- You earn <€50K/year (progressive rates are worse than Italy’s).
- You need EU banking (blacklisted).
- You plan to leave soon (exit tax).
Bottom Line:
San Marino is a niche tax haven—great for high earners, retirees, and crypto investors, but terrible for low-income expats, Americans, and those needing EU banking.
If you’re serious about moving, consult a San Marino tax advisor (expect to pay €300-500/hour).
