Spain self-employed quota 2026: full tier table and planning guide

Spain's real-income contribution system matters, but for digital freelancers the bigger question is structure: autónomo, SL or a US LLC for international clients.

Spain's special self-employed scheme (RETA) has contributed on real income since it came into force and, currently, the consolidated tiers are no longer a novelty but a major fixed cost to plan for. The monthly quota ranges from around 205 euros for the lowest net incomes up to nearly 1,607 euros per month if you opt for the maximum base of the top bracket. On the minimum base of each tier, the amounts are noticeably lower: up to around 607 euros per month for incomes above 6,000 euros. This guide compiles the current table, explains how your computable net income is calculated, what allowances exist and when it pays to look at alternatives such as the US LLC, especially if your activity is 100% digital and most clients are outside Spain.

Quota table by income tier

The current system splits self-employed workers into fifteen tiers by monthly net income. On the minimum base of each tier, the lowest tiers (up to 670 euros net) contribute around 205-225 euros per month; the middle tier (1,700-2,030 euros net, where many freelancers cluster) hovers at 360-380 euros; and the highest tiers (above 6,000 euros monthly) reach 607 euros. If you elect the maximum base of your bracket instead of the minimum, the fee can climb to roughly 1,275 euros per month in the upper-middle brackets and to 1,607 euros per month in the top bracket. The quota covers common and professional contingencies, cessation of activity and training, and grants access to Social Security coverage. Regularisation happens at year end, adjusting what was paid to the real income declared on the IRPF return.

What counts as computable net income

Computable net income for contribution purposes is gross income minus deductible expenses, less 7% for personal autonomos and 3% for company autonomos as a generic expense allowance. It is not exactly the same as IRPF net income, which causes much confusion. Spain's Social Security Treasury (TGSS) sets a provisional base on registration and you can change it up to six times a year based on your real forecast. A combined 31.5% rate (covering common and professional contingencies, cessation of activity, training and the MEI contribution) is then applied to that base to obtain the quota due.

Allowances and flat rate

The 80 euro monthly flat rate remains for the first twelve months of activity for new autonomos, extendable for another twelve if net income is below the minimum wage. Specific allowances also exist: disability above 33%, gender violence victims, family collaborator autonomos, Ceuta and Melilla, and autonomas returning after maternity. Each allowance has its own deadlines and conditions, and it pays to apply formally from day one because retroactive claims are hard. A good adviser typically recovers their annual fee just by claiming well-planned allowances.

Side by side: what RETA really costs you

Adding the quota to IRPF gives a more realistic picture of the autonomo's combined fiscal-social cost. A freelancer invoicing 4,000 euros net monthly with a 380 euro quota pays around 4,560 euros annually in RETA alone, plus an effective IRPF of 25-30% on net income. The combined total can exceed 40% of invoicing. Compared to an employee with equivalent salary, the autonomo still contributes less when computed on the minimum tier base, but also receives a smaller pension. Planning means picking a contribution base that balances current quota and future rights.

How regularisations affect your liquidity

Every year, the TGSS reconciles provisional contributions against the real income declared on your IRPF. If you contributed at a lower base than appropriate, you get a supplementary bill; if you contributed above, a refund. This directly affects your liquidity: an autonomo whose income jumps significantly may face a multi-thousand-euro charge a year later. That is why it pays to adjust the provisional base four or five times a year as visibility becomes real, rather than waiting for year end. The Social Security electronic portal lets you do this in minutes.

When dropping RETA makes sense

For 100% digital profiles with mostly international clients, a <a href="/en/blog/us-llc-vs-spanish-autonomo-structure-banking-tax">well-structured US LLC</a> lets you deregister from RETA and operate as a legal entity from the US, with an annual maintenance cost far below the annual autonomo quota. The condition is that activity and invoicing genuinely move through the LLC, not as a mere facade. If your monthly base is around 6,000 euros and the minimum quota nears 607 euros (with the bracket maximum reaching 1,607 euros), the net saving can outweigh even the cost of coordinating with your Spanish tax adviser.

Check the current official table at the <a href="https://www.seg-social.es/" target="_blank" rel="noopener">Spanish Social Security portal</a> and consult <a href="https://www.boe.es/buscar/act.php?id=BOE-A-1994-14960" target="_blank" rel="noopener">Royal Legislative Decree 1/1994</a> regulating RETA. Under-contributing today can prove expensive tomorrow; over-contributing without need eats into your savings. The key is to set the base realistically and review it every quarter.

Why reading the self-employed contribution as an annual figure changes how it is planned

Reading the self-employed contribution as an annual figure rather than as a monthly outflow changes how it is planned and how it is felt. The annual reading allows the contribution to be matched to the income profile of the year and to be set aside in a way that respects the seasonality of the activity. The monthly reading, by contrast, tends to produce a disproportionate sense of fixed cost.

Calculate the full annual autónomo cost

The 2026 self-employed contribution reads more calmly when it's treated as a stable annual mapping between projected net earnings and the corresponding contribution base, rather than as a recurring surprise. The official brackets define a discrete relationship that does not change month to month, and the only piece that requires real attention is the projected net earnings figure used at the start of the year and any adjustment that's needed if the projection turns out to be materially different from the actual outcome.

How year-end regularisation actually lands in cash terms

The monthly RETA quota during the year is provisional and based on the income tier the freelancer declared at the start of the year (or last reviewed). At year-end, when the IRPF return reflects the real net income, Social Security reconciles the actual tier with the provisional one and issues either a top-up bill (if real income was higher than declared) or a refund (if it was lower). In our practice, the top-up bill is the most common surprise because freelancers tend to declare conservative tiers at the start of the year and exceed them when a strong quarter lands; the bill arrives several months after year-end, sometimes with two or three brackets of difference, and it must be paid in a single instalment. The clean approach is to recalculate the projected tier each quarter and request a tier change online before the deadline, so the year-end reconciliation is small enough to absorb without affecting cash planning.

Three liquidity profiles where the RETA quota hurts the most

The first profile is the freelancer in the bottom tiers but with strong seasonal income concentration: the monthly bill is small in absolute terms, but it falls during low-revenue months and represents a high percentage of cash inflow in those weeks. The second profile is the freelancer who recently moved up one or two tiers, because the gap between paying around 230 euros monthly and 360 euros monthly is felt immediately on the bank statement, especially if invoicing rhythm has not yet caught up. The third profile is the freelancer who entered the upper tiers (above 605 euros monthly) without yet considering a structural alternative; in this band the absolute amount paid each month for social coverage starts to invite a serious comparison with structures like a US LLC or a Spanish SL, depending on residency and client mix.

How a tier-change request works in practice

Changing the income tier on which the RETA quota is calculated is done via the Importass online portal of the Social Security, with effect from the first day of the following two-month window if requested before the cut-off (the precise dates rotate every two months). In our practice, the most efficient rhythm is to review the tier projection at each quarterly closing and request a tier change immediately when the projection moves by more than one tier from the currently registered one; the request takes a few minutes online with the digital certificate and produces a confirmation receipt that we keep on file. Two practical notes: a tier-change request applies forward, not retroactively, so the longer the autónomo waits the more reconciliation will land at year-end; and the reverse change (going down a tier when income drops) is equally important to request, because keeping a high tier registered when income drops produces an over-payment during the year that the year-end reconciliation will refund only several months later.

How to align the RETA tier with cash-flow reality

The clean alignment between the RETA monthly cost and the freelancer's cash flow comes from three habits. First habit: a quarterly net-income projection (year-to-date plus expected for remaining months) that is shared with the autónomo at each closing and used to validate the registered tier. Second habit: a small cash buffer (we typically suggest the equivalent of two monthly quotas) held aside specifically for any year-end reconciliation top-up that may land. Third habit: a clear separation between the operating account and the personal account, with the RETA quota domiciled on the operating account and reflected in the monthly profit-and-loss like any other recurring expense. This is the kind of routine that takes thirty minutes to set up and prevents the situation where a freelancer discovers a 1,200-euro top-up bill in April that lands on the personal account already committed to other expenses.

The monthly contribution is only one variable

Does the monthly self-employed contribution decide whether I should restructure? No. It is a visible cost, but a serious decision also reviews income tax, VAT, margin, continuity of activity, tax residence, client profile and payment flow. A high contribution can justify a review, but it does not automatically make a US LLC the right answer.

Does a US LLC automatically remove the Spanish self-employed issue? No. If the activity is still habitual, personal and effectively carried out from Spain, local obligations may remain. A US LLC only makes sense when residence, clients, banking, contracts and distributions support a coherent international structure.
