Consult a qualified cross-border tax advisor before changing your tax residency or structuring around residency rules.
Core Concepts
| Concept | Definition | Can You Change It? |
|---|---|---|
| Company incorporation | Where the business is registered | Yes — choose jurisdiction |
| Company tax residency | Where the business pays corporate tax (usually where it's managed) | Partially — depends on substance |
| Personal tax residency | Where YOU pay personal income tax | Yes — but requires genuine relocation |
Three separate concepts determine how an international founder is taxed:
For solo founders using pass-through entities (e.g., US LLC), personal tax residency is the primary tax determinant.
Most countries use 183 days of physical presence as a threshold for tax residency. However, the rule is more complex than it appears.
Variations by Country
| Variation | Countries | Detail |
|---|---|---|
| Any partial day = 1 day | Most countries | Arriving at 11pm counts as a full day |
| Calendar year basis | US (substantial presence), most EU | January 1 – December 31 |
| Fiscal year basis | UK (April 6), Australia (July 1) | Offset calendar |
| Additional tests beyond days | Germany, Netherlands, Japan | Family, property, "center of vital interests" |
| Permanent home test | Most OECD countries | Having a home available can trigger residency even with <183 days |
| Citizenship-based | United States | US citizens are ALWAYS US tax residents regardless of location |

When leaving a high-tax country, departure can trigger a large one-time tax bill. This is often the single largest tax event in a founder's life.
Exit Tax (Departure Tax) table
| Country | Rule | Trigger | Deferral? |

| Germany | § 6 AStG | Deemed disposal of shares in foreign companies on departure (>1% shareholding held 5+ years) | 5-year deferral within EU/EEA; installments for non-EU moves |

Planning guidance:
Countries WITH Formal Split-Year Treatment
| Country | Rule | Detail |
|---|---|---|
| UK | Statutory Residence Test (SRT) | 8 defined "cases" for split-year treatment; each half taxed separately |
| Germany | Prorated income | Unlimited liability ends on Abmeldung date; limited liability continues for German-source income |
| Australia | Partial-year resident | ATO determines residency date based on facts; foreign income not taxed in non-resident portion |
When two countries both claim a person as their tax resident, the DTA tie-breaker is applied sequentially:
Tax Treaty Tie-Breaker Rules (OECD Article 4) table (OECD Article 4)
| Step | Test | Key Details |
|---|---|---|
| 1 | Permanent home availability | Where do you have a home available for continuous use? Rented accommodation counts. A home rented OUT to tenants is NOT available. |
| 2 | Center of vital interests | Where are your closest personal and economic ties? Family, employment, bank accounts, property. Holistic assessment. |
| 3 | Habitual abode | Where do you spend time habitually? Assessed over an extended period, not just the current year. |
| 4 | Nationality | Citizenship as final tie-breaker. Dual nationals may fall through to mutual agreement (MAP, 24–36 months). |
Documentation Required for Tie-Breaker Claims
| Document | Purpose |
|---|---|
| Lease agreements / property ownership | Proves permanent home availability |
| Utility bills in your name | Evidence of actual use of accommodation |
| Passport stamps / border crossing records | Day-count evidence for habitual abode |
| Bank statements | Shows where economic life is centered |
| Business records (contracts, invoices) | Shows where economic activity is located |
| School enrollment records (children) | Strong personal ties evidence |
| Tax Residency Certificate (TRC) | Primary official evidence — single most important document |
Five "flags" that do NOT need to be in the same country:
Flag Theory for Solo Founders table
| Flag | What It Is | Can You Change It? |
|---|---|---|
| Passport | Citizenship | Difficult |
| Tax residency | Where you pay personal tax | Yes — requires genuine relocation |
| Company | Where your business is registered | Yes — choose based on customers/tax |
| Banking | Where your money is held | Yes — choose based on features/access |
| Living | Where you actually spend time | Yes — but must align with tax residency claim |
Example (legal): Chinese citizen → Dubai tax residency (5% PIT) → Wyoming LLC (0% US tax) → Mercury (US) + Wise (multi-currency) → Living in Dubai + travel.
