Alternative mutual society or RETA: what the self-employed lawyer should weigh before choosing

One of the first procedures of a lawyer going self-employed is also one of the most consequential: social protection. Registered professionals integrated in the Special Regime for Self-Employed Workers (RETA), regulated in the consolidated text of the General Social Security Law, can opt, under the terms of Law 10/2012, to cover common contingencies through an alternative mutual society instead of the Social Security.

It is not a minor decision, nor always reversible without conditions: it affects retirement, temporary incapacity and the annual cost of the practice. It deserves a calm comparison.

What each option covers

In RETA, the contribution covers common contingencies (common illness, public retirement) and professional contingencies (work accident and occupational disease), as well as cessation of activity and birth and childcare benefits, among other coverages of the regime. Since 2023 the contribution is set by net income brackets, with annual regularisation based on real income: we explained it in detail in The self-employed lawyer's contribution in 2026: brackets and regularisation.

The alternative mutual society is a social welfare entity that replaces the Social Security in managing common contingencies. Professional contingencies and the rest of mandatory coverage remain in the public system. The Mutualidad de la Abogacía is the historic case in the sector, although since the 2012 liberalisation other mutual societies admit legal professionals.

The differences that matter in practice

Retirement. In RETA, the public pension is calculated on contribution bases and years contributed. The mutual society may offer the benefit as a lump sum, an annuity or a mix, according to its rules, and some professionals value the liquidity of a lump sum at retirement. This is the difference that weighs most in the decision.

Temporary incapacity. The management and amount of sick pay can differ between both options. It is worth comparing waiting periods, percentages of the regulatory base and the complements each mutual society offers.

Cessation of activity. The so-called "self-employed unemployment benefit" is a public system benefit. The mutual society does not automatically replace it: whoever values this coverage must check how it remains covered.

Taxation. The RETA contribution is a deductible expense in income tax, and contributions to social welfare systems have specific treatment with legal limits. Members of the pre-existing entities also have a special regime of reduction for contributions that should be reviewed every year with the tax adviser, because the limits and requirements have changed in recent years.

Questions before deciding

1. What is the total annual cost of each option for my income level, including optional contributions?
2. Do I prefer a public pension based on years contributed or a mutual society lump sum/annuity at retirement?
3. How is cessation of activity covered in each scenario?
4. What happens if I want to switch options later, and what conditions does each entity require?
5. What complements (improved sick pay, associated pension plans) does each alternative offer and at what price?

An open debate in the sector

The framework is also moving: the profession has long been discussing the so-called gateway to RETA, the mechanism that would ease the return to the public system of those who opted for the mutual society, whose regulation is still pending, as we covered in The gateway to RETA for lawyers and procuradores. Until that channel materialises, the initial choice gains even more importance.

The decision should be taken with one's own numbers: request a benefit simulation from the mutual society and compare it with the theoretical RETA pension for our base and age. And it should be integrated with professional liability insurance and the rest of the practice's protection, which we cover in The lawyer's professional liability insurance. In the Solo practitioners section we will keep reporting every regulatory development.
