Your income moves with you. So do the questions.

Confirm the work arrangement

Check that your residence status permits the activity you intend to carry out. If you work remotely, ask the employer or clients how the move affects contracts, payroll and social-security arrangements. Review UGE’s international teleworker guidance if that is your intended route.

Tax residence is not just a day count

The Tax Agency identifies more than 183 days in a calendar year and the main base of economic activities or interests as alternative grounds for Spanish tax residence. Family circumstances can create a presumption, and treaty rules may resolve cases in which two countries consider you resident.

A residence permit and tax residence are different questions. Have an adviser consider your move date, income, business interests and relevant treaty together. Regional and foral rules may also matter; get advice for the place you will live.

Self-employment needs its own setup

Importass explains Social Security registration for autónomos and the related tax-registration steps. Establish the right start date, activity details and expected net earnings before starting. Ask which tax authority is responsible and which obligations apply to your activity.

Build your budget around the contribution and filing position that actually applies to you. A reduced contribution someone else received is not a reliable assumption for your own move.

Take a useful brief to your adviser

• Your proposed move date and time spent in each country.
• Employment, freelance income, pensions, investments and property.
• Any company ownership or ongoing activity abroad.
• Your partner’s circumstances and intended region of residence.

Agree who will handle registrations, filings and deadlines, and what their fee covers.
