  • This rate is transitional. The forty-fourth transitional provision steps the reduced rates down year by year until 2029, so the 19 % and 21 % of the scale and the 23 % for a small company are not the figures printed in article 29.1.
  • Passing €1,000,000.00 of turnover takes the company off the scale and onto the single small-company rate, which this year is 23 %: the second slice of profit starts costing more, not less.
  • This is the gross tax. No rebates or credits have been applied (R&D, double taxation, donations), which come off afterwards and can reduce it a great deal.
Capitalisation reserve (optional)

Reduces the base by a percentage of the increase in your own funds, and that percentage rises if average headcount grows. Leave at zero if you do not claim it.

An indicative calculation on the state rules. Not tax advice.

It excludes credits and rebates, the tax adjustments of articles 11 to 24, the co-operative regime, tax consolidation and the foral territories.

Five different rates in five years, for the same company

Law 7/2024 cut the rates for smaller companies, but not in one step. Its forty-fourth transitional provision sets a timetable: a company with under a million euros of turnover applies a scale of 21 and 22 per cent in 2025, 19 and 21 in 2026 and 17 and 20 from 2027; a small company, under ten million, pays 24 in 2025, 23 in 2026, 22 in 2027, 21 in 2028 and 20 in 2029. Note the asymmetry, because it is the provision’s own structure: paragraphs 3 and 4 mention only the small-company rate, so the micro-company scale reaches its destination two years earlier. The general 25 per cent never moved.

Crossing a million costs money, and in the direction nobody expects

The micro-company scale and the single small-company rate are not two steps of one staircase. In 2026 a company with 900,000 euros of turnover pays 19 per cent on the first 50,000 euros of base and 21 on the rest; one with 1,100,000 pays 23 per cent on all of it. On a base of 200,000 euros that is 41,000 against 46,000. Two hundred thousand euros more of turnover makes the second slice of profit dearer, not cheaper, and there is no error-de-salto correction to soften the step the way Spanish inheritance tax has one.

The capitalisation reserve, with the headcount scale 2025 introduced

Article 25 lets you take a percentage of the increase in your own funds off the base, in exchange for keeping it for three years and booking an undistributable reserve for the same amount. Since 2025 that base percentage is 20 per cent and it rises with average headcount: 23 per cent if it grows by between 2 and 5 per cent, 26.5 if by between 5 and 10, and 30 if by more than 10. The cap is 20 per cent of the positive base, or 25 per cent where turnover stays below a million, and what does not fit is carried for two years. Read the middle figure carefully: the statute says 26.5 per cent, not 26.

The two reliefs run in sequence but are measured in parallel

The capitalisation reserve comes before loss relief, and that ordering is where the most expensive spreadsheet error on this tax lives. Article 26.1 does not cap the relief at 70 per cent of what is left after the reserve: it caps it at 70 per cent of “la base imponible previa a la aplicación de la reserva de capitalización establecida en el artículo 25 de esta Ley y a su compensación”. Article 25 measures its own cap on that same magnitude. Both reliefs are computed on the same base before reliefs, so neither shrinks the other. The only thing that binds afterwards is that the base cannot go negative.

5

And 25 July, which this year is not the 25th

Article 124.1 does not give a date: it gives a calculation, “el plazo de los 25 días naturales siguientes a los 6 meses posteriores a la conclusión del período impositivo”. For a calendar year end that is 1 to 25 July, which is why 25 July appears everywhere. In 2026 it falls on a Saturday, so the 2025 form 200 is due on Monday the 27th, exactly as the taxpayer calendar publishes it; in 2027 it falls on a Sunday and is due on Monday the 26th. The direct-debit window moves with it under article 3.2.b) of Order EHA/1658/2009, which extends it by the same number of days, and there is a footnote almost nobody quotes: you can only direct-debit the payment where the year ends on 31 December.

Worked example

An example, and it is the calculator’s opening state. An ordinary company turned over 900,000 euros in 2025 and reaches the 2026 tax period with a base before reliefs of 200,000 euros, no losses carried forward and no capitalisation reserve. Because it is under a million, the 2026 micro-company scale applies: 50,000 euros at 19 per cent is 9,500 and the remaining 150,000 at 21 per cent is 31,500, so the gross tax is 41,000 euros and the effective average rate 20.5 per cent. A guide using the 17 and 20 of article 29.1 would have told it 38,500 euros: 2,500 euros too little. Now move one figure and the second finding appears. Set turnover to 5,000,000 euros, the base before reliefs to 2,000,000, an increase in own funds of 1,000,000 and 3,000,000 of losses carried forward. The reserve takes off 200,000 euros, 20 per cent of the increase, well under its 400,000 cap. And loss relief admits 1,400,000 euros, 70 per cent of the 2,000,000 base before reliefs, not 70 per cent of the 1,800,000 left after the reserve. The taxable base comes to 400,000 euros and the tax, at 23 per cent, to 92,000. Computed in cascade it would have been 124,200: a difference of 32,200 euros for reading article 26.1 carefully.

Frequently asked questions

What is the Spanish corporation tax rate in 2026?
The general rate is still 25 per cent. What changed are the reduced ones: in a tax period starting in 2026, a company with under a million euros of turnover in the previous year applies a scale of 19 per cent on the first 50,000 euros of base and 21 on the rest, and a small company, under ten million, pays 23. The 17, 20 and 20 printed in article 29.1 arrive later, because the forty-fourth transitional provision phases them in until 2029.
Why does my adviser give a different rate from the one I read online?
Almost certainly because the page you read cites article 29.1 and your adviser applies the forty-fourth transitional provision. Both are the law: the article says what the rate will eventually be and the transitional provision says what is paid each year on the way there. On a base of 200,000 euros in 2026 the difference is 2,500 euros for a micro company and 6,000 for a small one.
What is a small company for this tax?
Under article 101, one that turned over less than ten million euros in the immediately preceding tax period and is not an asset-holding company. If it belongs to a group under article 42 of the Commercial Code, turnover is measured across the whole group. And there is an extension that is rarely mentioned: paragraph 4 of that article keeps the incentives for the three periods after the ten million is crossed, provided the entity qualified in that period and in the two before it.
Does an asset-holding company pay less?
No, it pays 25 per cent however small or however new it is. The closing paragraph of article 29.1 says the 20, 17 and 15 per cent rates “no resultarán de aplicación a aquellas entidades que tengan la consideración de entidad patrimonial”. Article 5.2 defines one as a company more than half of whose assets are securities or are not used in an economic activity. A company set up to hold flats for letting with no full-time employee falls there.
How much does the capitalisation reserve reduce?
Since 2025, 20 per cent of the increase in own funds, rising to 23 per cent where average headcount grows by between 2 and 5 per cent, to 26.5 where it grows by between 5 and 10, and to 30 where it grows by more than 10. The cap is 20 per cent of the positive base before reliefs, or 25 per cent where turnover did not reach a million, and what does not fit is used in the next two periods. In exchange the increase must be kept for three years and an undistributable reserve booked for the same amount.
When is form 200 filed?
Within the 25 calendar days following the six months after the year end. For a calendar year that is 1 to 25 July, but in 2026 the 25th is a Saturday and the window closes on Monday the 27th; in 2027 it is a Sunday and it closes on Monday the 26th. To direct-debit the payment you have until 22 July 2026, and only if your year ends on 31 December.
What is the 15 per cent minimum tax?
Article 30 bis stops credits from taking the net tax below 15 per cent of the taxable base, and it only reaches a company that turned over at least twenty million euros in the preceding twelve months or files in a tax group, whatever its turnover. The percentage drops to 10 per cent for a newly created company and rises to 18 for banks and hydrocarbons companies. For a micro or small company inside a group, the rule is to multiply its rate by fifteen twenty-fifths and round up.
Does this calculator include credits and rebates?
No, which is why it returns a gross tax rather than an amount payable. The rebates and credits of articles 31 to 39 (double taxation, R&D, film production, job creation) turn on facts no input here carries and can reduce the bill a great deal. It also excludes the tax adjustments of articles 11 to 24: the base you are asked for is the accounting result already corrected.
What about co-operatives?
They are deliberately out of scope. Article 29.2 cuts three points off the rates of the previous paragraph “siempre que el tipo resultante no supere el 20 por ciento”, and on the general 25 per cent that proviso admits two readings that give different answers. The regime also separates co-operative from non-co-operative results under Law 20/1990, which this page does not implement. Before relying on a figure for a co-operative, check that law.
Does this apply in the Basque Country and Navarre?
No. Álava, Bizkaia, Gipuzkoa and the Chartered Community of Navarre levy their own corporate income tax, with their own rates, incentives, forms and deadlines. This page describes the common-territory regime.
