Clear promise

By the end of this guide, you should be able to make a confident go/no-go decision and execute the next steps without guessing.

Quick reality check

This path is usually a good fit if:

• You want to quantify tax impact before committing to a city or visa path.
• You prefer compliance-first planning over paying to fix late filings.

This path is harder if:

• You have cross-border income, pensions, or assets with mixed tax treatment.
• You are moving mid-year and your tax residence may split across countries.

Decision questions to answer first

• Which assets are likely in-scope under your residency status?
• How do regional rules change your expected burden?
• What legal planning steps should be done before becoming resident?

Step-by-step main guidance

1. Create a full net-worth map before relocation date.

2. Model tax outcomes under likely regional scenarios.

3. Check interaction with other reporting obligations.

4. Sequence ownership or residency planning before trigger dates.

5. Prepare annual update process for valuations and supporting records.

Costs, timing, and required documents

Use these ranges for planning, not as guarantees:

• Data collection and classification: 1 to 4 weeks for most households.
• Advisor review and planning model: 1 to 3 weeks depending on complexity.
• First filing cycle in Spain: quarterly and annual deadlines require calendar setup.

Core documents to prepare:

• Global asset inventory with ownership percentages and valuations.
• Documentation for real estate, portfolios, companies, and cash positions.
• Debt records that may affect taxable base calculations.
• Regional residency assumptions tied to your city plan.
• Historical valuations for assets with volatile pricing.

Common mistakes and how to avoid them

• Choosing city/region before modeling regional tax treatment.
• Using rough market estimates without documentable valuation basis.
• Confusing immigration residency dates with tax residency rules.

Final action plan: what to do this week

1. Build an asset and liability sheet with ownership detail.
2. Run at least two regional tax scenarios.
3. Collect valuation evidence for largest positions first.
4. Set annual valuation and filing reminders.
