1) Initial contact and information gathering: you contact the office and they request details of your personal and fiscal situation.

2) Situation analysis and proposal: they analyse residency, income sources, assets abroad and suggest a plan (tax residence, applicable treaties, or special regimes such as Ley Beckham).

3) Implementation and registrations: they submit necessary forms, liaise with AEAT and other authorities, and complete registrations (e.g., Model 720) where applicable.

4) Ongoing compliance: they provide year‑round accounting, tax returns and advisory services while you remain a client. (Process described across their expat and service pages.)
