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 quarterly and annual filings apply to your activity profile?
- Which deadlines need advance prep for cash flow and documentation?
- Will you self-file or delegate to a gestor (administrative agent) with clear controls?
Step-by-step main guidance
1. Build a year calendar with quarter-end prep checkpoints.
2. Close books monthly so quarter filings are low-friction.
3. Reconcile invoices, bank activity, and tax categories.
4. File on time and archive proof immediately.
5. Review each quarter for errors before year-end filings.
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:
- Monthly invoice register for income and deductible expenses.
- VAT evidence and exemption support where relevant.
- Bank reconciliations aligned with invoice periods.
- Social security contribution records and payment confirmations.
- Calendar with deadline alerts and submission receipts.
Common mistakes and how to avoid them
- Doing bookkeeping only at filing week and missing evidence gaps.
- Treating VAT and income tax records as separate unlinked systems.
- Confusing immigration residency dates with tax residency rules.
Final action plan: what to do this week
- Create a recurring monthly close routine for bookkeeping.
- Set reminders 21 and 7 days before each filing deadline.
- Build a standard folder structure for each tax quarter.
- Run first reconciliation between invoices and bank statements.
