Spain Autónomo Taxes Explained (2026)

An autónomo in Spain invoicing €40,000 a year with no deductible expenses keeps about €27,600 in 2026 — roughly 31% of gross income goes to IRPF and social security combined. In the first year of activity, the same person keeps about €32,950, because the social security quota drops to €88.64 a month and a fifth of the taxable base disappears.

Those two numbers describe most of what matters about being self-employed in Spain. The rest of this guide explains where they come from, and the three places where the arithmetic is more complicated than the usual summaries admit.

Two bills, two calendars

Being autónomo means paying into two systems that never talk to each other.

IRPF is personal income tax, settled once a year in the declaración de la renta. It runs on progressive brackets and is calculated on your profit after expenses.

The RETA cuota is your social security contribution. It is a monthly bill, charged whether or not you made money that month, and since the 2023 reform it is scaled to what you actually earn rather than being a flat fee you choose.

Almost every misleading claim about Spanish freelance tax comes from quoting one and ignoring the other. “Autónomos pay 19% up to €12,450” is an IRPF statement that says nothing about the €200–€600 leaving your account every month regardless.

The cuota: fifteen tramos, and how yours is picked

Before 2023 you chose your own contribution base, and almost everyone chose the minimum. Now the Seguridad Social sorts you into one of fifteen income brackets — tramos — and each tramo has its own quota.

The income figure used to place you is not your invoiced revenue and not quite your profit either. It is your net income plus the social security quotas you paid, reduced by a generic 7% deduction (3% for autónomos societarios), divided by your months of activity. Adding the quotas back before applying the 7% is the step most explanations skip, and it moves people a tramo or two.

For 2026 the quotas at each tramo’s minimum base run from €205.88 to €607.35 a month including the 0.9% MEI surcharge. The contribution rate itself is 30.6% — 28.30% common contingencies, 1.30% professional contingencies, 0.90% cessation of activity, 0.10% vocational training — plus the MEI on top, giving 31.5% all in.

A few representative points, for someone with no deductible expenses:

Gross invoiced	Monthly income used for the tramo	Cuota per month
€20,000	€1,550	€302.65
€30,000	€2,325	€401.47
€40,000	€3,100	€452.94
€50,000	€3,875	€504.41
€75,000	€5,813	€545.59
€100,000	€7,750	€607.35

Notice how flat the top of that curve is. Social security stops being a meaningful percentage of income well before €100,000 — it is 18% of gross at €20,000 and 7% at €100,000. Spain is expensive for low earners and comparatively cheap for high ones, which is the opposite of how the system is usually described.

You can also choose to contribute on a higher base than your tramo’s minimum. Nobody does, but it raises your future pension, and it is the only lever you have over the number.

The 5% allowance that most guides still get wrong

Under estimación directa simplificada — the default regime while turnover stays under €600,000 — you deduct your real business expenses, and then you get one extra deduction for costs you cannot document.

That allowance is 5% of net income, capped at €2,000 a year.

A large share of the Spanish tax content online still says 7%. The Agencia Tributaria’s own guidance settles it in a parenthesis: the rate is “5% (7% para 2023)”. Seven percent was a one-year measure for the 2023 tax year only, and it reverted afterwards. If a calculator or a gestoría quote is using 7%, it is overstating your deduction by up to €800 of taxable base.

This is the single most common error in the Spanish freelance tax material, and it is worth checking whoever files your return is not making it.

What you actually keep

Putting both systems together, for an autónomo in a regular (non-first) year, with no deductible expenses, single, no dependents:

Gross invoiced	Social security	IRPF	Total	Net income	Effective rate
€20,000	€3,632	€2,055	€5,687	€14,313	28.4%
€30,000	€4,818	€4,288	€9,106	€20,894	30.4%
€40,000	€5,435	€6,962	€12,397	€27,603	31.0%
€50,000	€6,053	€10,167	€16,220	€33,780	32.4%
€75,000	€6,547	€19,751	€26,298	€48,702	35.1%
€100,000	€7,288	€30,667	€37,956	€62,044	38.0%

The curve is much flatter than people expect — 28% at €20,000 rising only to 38% at €100,000. That is the flat social security ceiling doing the work: IRPF climbs steeply, but the cuota barely moves, so the two partly cancel.

Real expenses shift every row down. You can put your own figures in with the Spain Autónomo Tax Calculator, which uses exactly the tramo table and rates above.

The first year is genuinely cheap

Two reliefs stack for new autónomos.

Tarifa plana replaces the tramo quota with a flat €80 a month, or €88.64 including MEI, for the first 12 months. It extends for a second 12 months if your net income stays below the minimum wage.

A 20% IRPF reduction applies to net income in the first tax period with positive profit and the one after, on at most €100,000 of net income. It requires that you were not carrying on another activity in the year before starting.

Together they change the picture completely:

Gross invoiced	First year total	First year net	Regular year total	Regular year net	Difference
€30,000	€4,772	€25,228	€9,106	€20,894	€4,333
€40,000	€7,052	€32,948	€12,397	€27,603	€5,345
€50,000	€9,604	€40,396	€16,220	€33,780	€6,617

At €40,000 the effective rate is 17.6% in year one and 31.0% once the reliefs end. Budget on the second number. The most common financial mistake new autónomos make is treating the first year’s take-home as their normal income.

Where you live changes the bill

Spanish IRPF has two halves. The state half is fixed by law and identical everywhere:

Taxable base	State rate
€0 – €12,450	9.50%
€12,450 – €20,200	12.00%
€20,200 – €35,200	15.00%
€35,200 – €60,000	18.50%
€60,000 – €300,000	22.50%
Above €300,000	24.50%

The other half is set independently by each comunidad autónoma, and they do not agree with each other — not on the rates, and not even on where the brackets sit. Madrid uses five brackets topping out at 20.50%. Cataluña uses eight, topping out at 25.50%. Comunitat Valenciana uses eleven, topping out at 29.50%. Combined with the state half, the top marginal rate is 45% in Madrid, 50% in Cataluña and 54% in Comunitat Valenciana.

The figures in this guide use the combined reference scale of 19% / 24% / 30% / 37% / 45% / 47%. Here is what the regional choice actually costs, on the same taxable base:

Gross invoiced	Madrid	Reference scale	Cataluña	C. Valenciana	Cheapest → dearest
€30,000	€4,041	€4,288	€4,299	€4,213	€258
€40,000	€6,519	€6,962	€7,063	€6,908	€543
€60,000	€13,001	€13,685	€13,956	€13,763	€955
€100,000	€29,358	€30,667	€30,864	€32,073	€2,715

Two things worth noticing. Madrid is cheapest at every level, but the dearest region changes: Cataluña costs most at middle incomes because its lower brackets start higher, while Valencia overtakes it past €60,000 as its long ladder of upper brackets kicks in. And the reference scale is not a safe midpoint at the top — at €100,000 it is the second-cheapest of the four.

At ordinary freelance incomes the spread is a few hundred euros a year: real, but not a reason to move. Above €60,000 it becomes substantial. Treat any single “Spanish tax rate” figure, including the ones in this guide, as approximate until you apply your own region’s scale.

The regularización nobody warns you about

Your tramo is provisional. You pick it from your own income forecast, and you can change it up to six times a year as that forecast changes.

Afterwards, the Seguridad Social compares what you paid against the income Hacienda actually recorded. If you under-contributed, you get a bill for the difference. If you over-contributed, you are refunded.

The practical consequence is that your first full year as an autónomo can end with an unexpected settlement, in either direction, arriving long after the year is over. Forecast honestly rather than optimistically, and keep the difference set aside.

What this guide does not cover

The figures assume a resident taxpayer, single with no dependents, individual autónomo rather than societario, estimación directa simplificada, and Category-equivalent business income only. Several things change the answer materially:

• Your comunidad autónoma, as above — and several also add their own deductions and modify the personal minimum beyond the €5,550 used here.
• Módulos (estimación objetiva), an alternative regime for certain activities, which computes profit from indicators rather than real income.
• IVA, which sits on your invoices quarterly and is separate from everything discussed here.
• The Beckham regime, a flat 24% option for qualifying new arrivals in employment — if you qualify, none of the arithmetic above applies to you.
• Double taxation treaties, which decide who taxes what when your clients are abroad.

Spain is not a cheap country to freelance in once the first-year reliefs end, but it is a predictable one: the cuota is capped, the brackets are public, and the main surprises are administrative rather than financial. If you are weighing it against its most common alternative, we compared the two directly in Portugal vs Spain for Freelancers.
