Spanish businesses and investments
Opening a local business in Spain as a U.S. citizen
Of course, before opening a local business in Spain, you must have the right to live and work in Spain. You will also need to obtain a work permit. Moreover, you must decide on your business structure and register your business with the Spanish tax authorities.
Types of local business structures in Spain and the U.S. filing requirement
Sole Trader (Empresa Individual)
As a Sole Trader, you are self-employed. You must report your self-employment to the IRS via form Schedule C (included in our PREMIUM package).
SA, SLNE, SRL/SL, SLA, SLL, and SC
In Spain, there are six types of limited companies you can choose including Sociedad Anonima (S.A.), Sociedad Limitada Nueva Empresa (SLNE), Sociedad Limitada (SRL / SL), Sociedad Laboral Anónima (SLA), Sociedad Laboral Limitada (SLL), and Sociedad Cooperativa (S.C.). The main differences between these limited companies are the minimum number of shareholders required and the minimum investment amounts. These limited companies are reported to the IRS via Form 5471.
Sociedad civil/Partnership
Expats planning to go into business with one or more people may decide to register their business as a partnership. You must report the block to the IRS via Form 8865.
Pequeñas Y Medianas Empresas (PYME)
Small and medium-sized businesses (corporations) are reported to the IRS via Form 5471.
Social Security and pensions
The Spanish Social Security system is similar to many other European countries and is structured into three pillars:
Pillar I - State pension: The Spanish state pension is compulsory for all residents working in Spain, and contributions are deducted from your wages. The amount you receive as a pension depends on your earnings history and the number of years you have contributed to the system. It has strict regulations on who can claim and when (Social Insurance and survivor's annuities).
Pillar II - Company and employee pensions: Company-sponsored pensions and contributions to these pensions are typically made by both the employer and the employee. The availability and conditions of these pensions can vary depending on the employer.
Pillar III - Private pensions: Private pensions are voluntary and provide individuals with an option to save additional funds for retirement. These pensions offer more flexibility in terms of contributions and withdrawals compared to the Spanish state pension. For example, some private pensions allow you to withdraw your savings before reaching the Spanish pension age.
Note: the U.S.-Spain Tax Treaty helps prevent double taxation of Social Security benefits. Under the treaty, if you are a resident of Spain and you are receiving Social Security benefits, those benefits are generally only taxable in Spain. This means that you won't typically pay U.S. federal income tax on your Social Security income if you are a resident of Spain. However, some U.S. states may choose to tax these benefits. The rules vary by state, so it is essential to check your specific state's tax laws. Our Tax projection service can help you with that.
