Guide for the Self-Employed in Spain: Classification, Contributions Based on Real Income, Taxes and Rights

The community of self-employed workers in Spain (registered under the RETA, the Special Scheme for Self-Employed Workers) exceeds three million professionals. It is one of the most dynamic engines of the productive economy, but also the one that bears the heaviest bureaucratic burden and ongoing regulatory uncertainty.

With the entry into force of the new system of contributions based on real net earnings and the mandatory digitalization of invoicing, knowing precisely the different categories of self-employed worker, the tax calendar and the actual coverage you are entitled to is essential in order to avoid committing infractions against the Administration.

1. Classification: What type of self-employed worker are you?

• 1. Self-Employed Individual (Professional or Business Owner): The classic category. Carries out a professional activity (subject to personal income tax withholding on invoices when selling to companies) or a direct commercial activity. Bears unlimited liability with all of their assets.
• 2. Corporate Self-Employed Worker: Someone who holds the position of director or owns more than 25% of the capital with management functions (or 33% of the share capital) in a Limited Liability Company. Their minimum contribution base is set by law within specific brackets.
• 3. TRADE Self-Employed Worker (Economically Dependent): Someone who receives at least 75% of their annual income from a single client or payer. By law they are entitled to a contract registered with the SEPE (Public Employment Service) that guarantees them a minimum of 18 working days of paid holiday per year and reinforced protection against the unjustified termination of the contract.
• 4. Collaborating Self-Employed Worker: A spouse or relative up to the second degree (children, parents, siblings) who lives with and works on a regular basis alongside the registered self-employed worker without having a traditional salaried payroll. They benefit from 50% and 25% reductions in their Social Security contribution during the first two years.

2. The new system of contributions based on real income

Gone is the possibility of freely choosing the minimum contribution base regardless of how much you earned. Since the RETA reform, the self-employed contribute on the basis of a table of 15 brackets of real net earnings (income minus deductible business expenses, plus a 7% generic deduction for expenses that are difficult to justify):

• Flat Rate for New Self-Employed Workers: During the first 12 months of registration, new professionals pay a reduced fixed contribution of 80 euros per month (extendable for a further 12 months if their earnings remain below the National Minimum Wage).
• Mandatory annual regularization: Each year, Social Security cross-checks data with the Tax Agency. If you contributed under a bracket lower than the one that corresponded to your income tax return, you will have to pay the difference; if you contributed too much, Social Security will refund the excess automatically.

3. Obligations and the quarterly tax calendar

A self-employed worker’s year is structured around four unavoidable appointments with the Tax Office (April, July, October and January):

• Form 303 (Quarterly VAT): You settle the difference between the VAT you have charged on your invoices (output VAT) and the VAT you have paid on expenses related to your work (input VAT). VAT is never yours; you act merely as a collector for the State.
• Form 130 (Personal Income Tax installment payment): For self-employed workers under the direct assessment method. You pay 20% of the net profit obtained so far in the year in advance (unless more than 70% of your invoices are issued with prior withholding to Spanish companies, in which case you are exempt from filing it).
• Forms 111 and 115: If you hire employees, subcontract independent professionals with withholding, or rent a commercial premises or office with personal income tax withholding.
• Annual informative summaries: Forms 390 (VAT) and 190 (Personal Income Tax), which compile all the operations of the financial year.

4. Social rights and benefits: Myths and realities

Although it was traditionally said that «the self-employed have no rights», the current contribution includes social coverage almost identical to that of the General Scheme:

• Temporary Incapacity (Sick leave): Covers common contingencies from the 4th day of leave (60% of the regulatory base up to day 20, and 75% from then on) and professional contingencies from the first day. From day 61 of sick leave, the mutual insurer also assumes the payment of your self-employed contribution.
• Birth and Childcare Leave: 16 weeks paid at 100% of the regulatory base with a 100% exemption from the self-employed contribution.
• Cessation of activity («The self-employed worker’s unemployment benefit»): A financial benefit if you have to close your business due to justified objective economic causes (demonstrable continued losses of more than 10% in one year).

«Being self-employed in Spain requires being excellent at your trade and disciplined with your numbers: keeping the business account separate from the personal one and religiously setting aside the VAT every month is the key to survival.»
