NIF vs. NIE
For individuals, your NIE functions as your NIF (tax ID) once assigned — Spain doesn’t issue a separate tax number to most foreigners. Modelo 030 is how you register/update your fiscal address and personal data with Hacienda.
The 183-day residency rule
You’re a Spanish tax resident for a given year if you spend more than 183 days in Spain, or your main base of economic activity is in Spain, or your spouse and minor children habitually live in Spain (a rebuttable presumption). ⚠ Some tax advisors flag that the “center of economic interests” test can trigger residency even under 183 days — don’t treat the day-count as the full picture.
The Beckham Law (Régimen Especial de Impatriados) — read this carefully
- Since the 2023 Startups Law reform, this explicitly covers people arriving on the international teleworker (digital nomad) visa, alongside standard employees, company administrators, and startup founders.
- You must not have been a Spanish tax resident in the prior 5 years.
- The benefit: qualifying income is taxed at a flat 24% rate (up to €600,000) instead of Spain’s progressive resident scale, which reaches roughly 47% at the top bracket — for 6 total years (year of arrival plus 5 more).
- How to apply: file Modelo 149 with Hacienda. The deadline is 6 months from your Social Security registration date, and it’s hard and non-extendable — miss it by a day and you reportedly lose the right permanently.
Given the visa’s income floor is already north of €34,000, this is one of the most financially consequential facts for anyone who qualifies — put a reminder in your calendar the day you register with Social Security.
