The 183-day rule in Spain
You are tax resident in Spain for a calendar year if you spend more than 183 days in Spanish territory during that year, if the main centre of your economic activities or interests is in Spain, or (rebuttable presumption) if your spouse and dependent children live there (Ley del IRPF, art. 9). There is no split year: you are resident or non-resident for the whole calendar year.

How the rule works
Two features make Spain stricter than a plain day count. First, sporadic absences are added back: short trips abroad count as days in Spain unless you can prove you were tax resident in another country for that year, and if that country is on Spain's tax-haven list you must show 183 days of actual presence there. Second, there is no partial-year residence: cross the line in December and you are resident for the whole year, including income earned before you arrived.
The economic-interests test looks at where your main income sources, assets and business activity are. Employees relocating can opt into the special "Beckham" regime (taxed like a non-resident at flat rates for six years) if they apply within six months of registering with social security.
Spanish residents are taxed on worldwide income, must file Modelo 100 and, above thresholds, declare foreign assets on Modelo 720. Because sporadic absences count against you, a contemporaneous record of every entry and exit is the single most useful piece of evidence in a residence dispute.
Counting your days
Open the 183-day calculator with the Spain preset: it applies the right period (calendar year (1 january – 31 december)) and threshold, counts arrival and departure days, and shows how many days remain. For a full record with evidence per trip and a PDF you can hand to the tax authority, use the app.
