Getting into the regime is a one-off application. Staying in it correctly is a return every year, on a form of its own, with rules that differ from the ordinary Spanish return in almost every line.

People under the special regime for inbound workers do not file the ordinary Spanish income tax return. They file form 151, between April and June, and it works on a different basis:
The practical consequence is that the return looks simple and is easy to get wrong. The usual errors are including foreign investment income that should be left out, leaving out employment income paid from abroad that should be in, and applying allowances that belong to the ordinary regime.
For many people in the regime, the largest item is not salary. Stock options exercised, restricted stock units that vest and employee share plan discounts are employment income. Under the regime they are taxed in Spain at the flat rate in the year they are received, including, in general, the part that relates to work done before arriving.
That raises three questions each year: in which year the income arises, how much of it another country also claims, and what relief is available for tax paid there. The answers depend on the plan and on the treaty. The underlying rules are covered under stock options and RSUs; the yearly return is where they are applied.
An engineer on €140,000 of salary has RSUs worth €90,000 vest during the year. Employment income is €230,000, taxed at 24 %: €55,200. Dividends of €6,000 from the US shares she holds are not taxed in Spain under the regime. Interest of €400 on her Spanish account is taxed at 19 %.
The regime applies in the year you become resident and the five that follow. It ends earlier if you stop meeting its conditions, for instance if the employment that justified it ends and is not replaced within the permitted time, or if you waive it. Exclusion and waiver are notified on form 149, with deadlines.
The last year deserves planning. From the seventh year you are an ordinary resident: worldwide income is taxed on the progressive scale, foreign assets become reportable on form 720, and wealth tax covers assets everywhere. Decisions such as selling shares, drawing a bonus or restructuring investments are often better taken before that date than after. We raise it with you a year ahead.
The fee is €520 a year, taxes included. The initial application is separate work, described under Beckham law. Extending the regime to a spouse and children is quoted from €460.
