Step-by-step

1
Work out whether you are tax resident, and from when
More than 183 days in a calendar year makes you resident, as does having your centre of economic interests in Spain. Residency is assessed for the whole calendar year rather than pro-rated, which produces surprising results for people arriving mid-year.

2
Understand that half of your income tax is Andalusian
IRPF combines a state scale with an autonomous community scale, and Andalusia sets its own and has reduced it. The same gross salary produces a different net in Málaga, Valencia and Barcelona.

3
Understand the wealth tax position and its limits
Andalusia rebates the regional wealth tax in full. The state introduced a temporary solidarity levy on large fortunes designed specifically to capture what regional rebates release, so the advantage is real at moderate wealth levels and much reduced at the top. This deserves an adviser rather than an assumption.

4
Decide on the impatriate regime inside its window
The régimen especial for displaced workers — the Beckham Law — taxes Spanish employment income at a flat rate rather than the progressive scale for a limited period, and was extended to arrivals under the digital nomad route. It must be elected within a strict period after social security registration and is not easily reversed. It favours higher earners and can be worse for lower ones.

5
File the Modelo 720 if you hold foreign assets
Tax residents must report overseas accounts, securities and property above a threshold in each of three categories. It is an information return with its own deadline, and it catches a very high proportion of arrivals here because so many keep property elsewhere.

File the annual Renta between April and June
The declaration for the previous calendar year is filed in the spring window. The Agencia Tributaria produces a draft — the borrador — which is often accurate for simple employment cases and materially wrong for anyone with foreign income. Do not confirm it without checking.

Things most newcomers don’t know

Andalusia rebates wealth tax; Valencia and Catalonia charge it.

The wealth tax is designed nationally but regions can rebate it, and Andalusia rebates it in full. For someone with significant assets, choosing Málaga over Valencia or Barcelona is a materially different outcome on identical Spanish residency. The caveat is the state solidarity levy on large fortunes, introduced precisely to capture what regional rebates release — so the benefit is real in the middle and thinner at the very top.

Málaga attracts people specifically for the tax position, which has consequences for everyone else.

The combination of Andalusia's rebated wealth tax, its reduced income tax scale and the impatriate regime is genuinely favourable, and it has drawn substantial numbers of high-earning arrivals. That is a real advantage if you are one of them. It is also inseparable from why the housing market moved as it did, and it is worth understanding that the two facts are connected rather than treating them as unrelated features of the city.

Spanish tax residency is worldwide and is assessed for the whole year.

Once you cross the 183-day threshold, Spain taxes your global income for the entire calendar year rather than from your arrival date. Someone arriving in May with substantial income earned abroad earlier in the year can find it falling into the Spanish net. If you have significant pre-move income, the difference between arriving in June and arriving in July can be very large.

The Modelo 720 catches an unusually high share of arrivals here.

The obligation to declare foreign accounts, securities and property applies to every Spanish tax resident, and Málaga's incoming population is disproportionately likely to have kept a house, a pension or an investment account somewhere else. The European Court of Justice struck down the original penalties as disproportionate and they were revised, but the reporting obligation is fully in force and the deadline is separate from the Renta.

Common mistakes to avoid

Assuming a single national income tax rate and ignoring the Andalusian regional scale.
Assuming the Andalusian wealth tax rebate is complete without accounting for the state solidarity levy.
Missing the Modelo 720 foreign-asset declaration, which catches a very high share of arrivals here.
Confirming the borrador unchanged when you have foreign income.
Missing the strict window to elect the impatriate regime.
