When Spanish corporation tax is filed, and what happens if you are late

The short answer, and why the date you have read is not the right one

The 2025 form 200 fell due on Monday 27 July 2026. Not the 25th, which is the date on almost every page that discusses this tax, and not through anybody's carelessness: 25 July is the correct answer to the calculation the law sets, except where that day is not a working one. In 2026 it fell on a Saturday.

That is the whole difference between the two dates, and the Spanish tax agency's own taxpayer calendar confirms it without ambiguity: the 2025 annual return of entities whose tax period coincides with the calendar year appears under the heading “Hasta el 27 de julio”³. In 2027 the 25th falls on a Sunday and the window will close on Monday the 26th.

If your year does not end on 31 December, or if your company was wound up during 2025, the date is a different one and the rules that set it are not where you would expect. Let us take them in turn.

Article 124.1 does not give a date, it gives a calculation

The rule says the return “se presentará en el plazo de los 25 días naturales siguientes a los 6 meses posteriores a la conclusión del período impositivo”¹. It mentions neither July nor any other month. You count six months from the year end, and 25 calendar days open from there.

For a calendar year the sum runs like this: year end 31 December, six months later is 30 June, and the 25 calendar days that follow run from 1 to 25 July. That is where the 25 July everybody repeats comes from. But where the last day is a Saturday, a Sunday or a national holiday, article 30.5 of Law 39/2015 moves the deadline to the next working day⁸, and that is what happens in 2026.

With any other year end the whole count shifts:

Notice that three of those five deadlines have moved. A 25 calendar day window that always ends on the same day of the month lands on a weekend two times in seven, so the “official” date is wrong very often. That is why the calculator on this page computes it instead of quoting it.

The two paragraphs of article 124.1 almost nobody cites, and that govern this campaign

After the general rule, the same article 124.1 adds something rarely mentioned: where the Ministry has not yet determined the form of filing the return for that period when the window opens, the return is filed “dentro de los 25 días naturales siguientes a la fecha de entrada en vigor de la norma que determine dicha forma de presentación”. And a paragraph later it allows the taxpayer to opt for the ordinary window using the previous period's formal requirements¹.

This is not a textbook hypothesis. Article 6.1 of Order HAC/529/2026 repeats the rule for this campaign word for word, and its second final provision brings the Order into force on 1 July 2026².

Who does it reach? Taxpayers whose window opened before that date, that is periods that began and ended inside 2025. Those are the short ones, the cases in article 27.2 of the tax act: the company that is wound up, the one that moves its residence abroad, the one whose transformation takes it out of the tax¹.

A concrete example. A company wound up on 31 October 2025 had an ordinary deadline of 25 May 2026, a perfectly ordinary Monday. In May 2026 the 2025 form 200 did not yet exist. Twenty-five calendar days from 1 July is Sunday 26 July, moved to Monday the 27th. That company was not late in May: the law had no form to give it.

And here is what makes this campaign unusual. A 31 December 2025 year end and a company wound up in October 2025 fall due on the same day, Monday 27 July 2026, by two completely different routes: the first through article 124.1 and a Saturday, the second through the Order's extension and a Sunday.

The option in the third paragraph is real too. That company's liquidator could have filed in May on the previous year's forms, approved by Order HAC/657/2025, in which case the ordinary deadline would have applied². In other words, they were choosing between two equally lawful deadlines two months apart.

Who has to file it, which is very nearly everyone

The most-searched question about this form is not when it is filed but whether it has to be, and the answer fits in one line of article 124.1: “los contribuyentes estarán obligados a presentar una declaración por este Impuesto”¹. The sentence ends there. No turnover threshold, no profit threshold, no headcount, no bank movements.

So a limited company that issued no invoice, paid no salary and moved no money all year files exactly the same form 200 as one with a million euros of profit. The only difference is that its boxes read zero.

The bodies that do not file are the fully exempt ones in article 9.1, and article 124.2 says so expressly: the State, the regions, local authorities, their agencies, the Bank of Spain, the social security managing bodies and a handful more¹.

The one relief there is points the opposite way to what you would guess

Article 124.3 has two sentences and they are worth reading apart. The first makes the entities in paragraphs 2, 3 and 4 of article 9 declare “la totalidad de sus rentas, exentas y no exentas”. The second relieves them of filing, but only “los contribuyentes a que se refiere el apartado 3”, on three conditions required at the same time¹:

1. Total income no higher than 75,000 euros a year.
2. Income from non-exempt sources no higher than 2,000 euros a year.
3. Every one of those non-exempt incomes withheld at source.

One condition failing is enough to make the return compulsory. And now the counterintuitive part: paragraph 2 of article 9 is the Ley 49/2002 regime, the good one, the one a foundation or an association opts into for the 10 per cent rate and for its donors' deductions. It is not in that second sentence.

The result is that a small association inside the better tax regime files for ever, while an identical one that stayed outside it may not have to file at all. What decides it is a cross-reference to a paragraph number, not anything about the size or the activity of the entity.

Three other things fall due around form 200, and another act sets them

Tax pages rarely put it beside the tax deadline, but the Spanish Companies Act sets three dates around the same set of accounts⁶:

• The directors draw up the accounts within three months of the year end (article 253.1).
• The ordinary general meeting approves them within the first six months of the year (article 164.1).
• The filing at the Commercial Registry follows within the month after that approval (article 279.1).

For a 31 December 2025 year end those are 31 March, 30 June and 30 July 2026. With form 200 on the 27th, the tax return sits between approval and registry filing.

And because form 200 includes the balance sheet and the profit and loss account, the consequence is that the company hands its accounts to the tax agency three days before it hands them to the Commercial Registry, in two different formats, to two different institutions and under two different penalty regimes.

One more detail that settles the question of meetings that slip: article 164.2 says the ordinary general meeting “será válida aunque haya sido convocada o se celebre fuera de plazo”⁶. The meeting may be late without ceasing to be valid. The form 200 deadline does not move for it.

The direct-debit window closes earlier, and is not open to everyone

If you want the payment charged to your account, the window is shorter than the filing one. Article 3 of Order HAC/529/2026 sets it for the 2025 year “desde el día 1 de julio hasta el 22 de julio de 2026, ambos inclusive”², five calendar days before the last day to file.

That 22nd is not an arbitrary number. Annex II of Order EHA/1658/2009 puts the form 200 window at 1 to 20 July, and its article 3.2.b) extends it by “el mismo número de días que resulte ampliado el plazo de presentación”, requiring in addition that at least three working days or five calendar days remain between the two closings⁷. Because the filing deadline was extended by two days, from the 25th to the 27th, direct debit moves from the 20th to the 22nd. And from 22 to 27 July there are exactly five calendar days and three working days: both floors are met precisely.

There is also a footnote almost nobody cites. The same annex II marks form 200 with an asterisk and explains: “Sólo cuando el período impositivo finalice el día 31 de diciembre”⁷. A company whose year ends in June and declares in January cannot direct-debit the payment at all, and has to settle it another way.

What being late on your own initiative costs

Form 200 is a self-assessment, not an information return, and that distinction decides everything that follows.

If you file it late yourself, before the administration has asked, article 27.2 of the General Tax Act applies: a surcharge “igual al 1 por ciento más otro 1 por ciento adicional por cada mes completo de retraso”, computed “sobre el importe a ingresar resultante de las autoliquidaciones”⁴. A month is complete when the same day of the following month is reached, so filing on 26 August and filing on 27 August do not cost the same.

Past twelve months the rule changes shape: the surcharge is fixed at 15 per cent and late-payment interest is added, running from the day after the end of those twelve months rather than from the original deadline⁴. There is therefore a real step: at eleven complete months the surcharge is 12 per cent with no interest, and at twelve it jumps to 15 per cent with interest.

On top of that surcharge, article 27.5 applies a 25 per cent reduction, conditional on paying the self-assessed tax when the return is filed and the surcharge within the window its notification opens⁴. Fail either and the reduction is clawed back without further formality.

If the return comes out at nil, there is no surcharge but a fine

Article 27.2 computes the surcharge on the amount payable. Where there is no amount payable, because the year was a loss, because the company was dormant or because the return is a refund, there is no base to apply anything to.

What applies then is article 198.1: a fixed fine of 200 euros for failing to file a self-assessment on time where no loss to the Treasury can arise. Paragraph 2 halves it to 100 euros where the return is late but filed before any demand, and article 188.3 allows a further 40 per cent off for prompt payment, which brings it to 60 euros⁵.

It is worth knowing that the 30 per cent reduction for agreeing with the assessment does not reach this far: article 188.1 grants it to penalties “impuestas según los artículos 191 a 197”, and article 198 is outside that list⁵.

The result is worth comparing with form 720, which also goes to the Spanish tax agency and never carries a surcharge, for the same reason and in every case: an information return never generates an amount payable. On form 200 the absence of a surcharge is the exception; on form 720 it is the rule.

And what it costs if the tax office asks first

All of the above is the price of going in voluntarily. Article 27.1 only applies to self-assessments filed “fuera de plazo sin requerimiento previo”, and it defines a prior demand as any administrative action, formally notified to the taxpayer, directed at recognising, regularising, checking, inspecting, securing or assessing the debt⁴.

If that action arrives before your return, the regime changes entirely. There is no longer a surcharge and article 191 takes over: it treats failing to pay the tax that a correct self-assessment would have produced as an infringement and penalises it proportionally, at 50 per cent where minor, 50 to 100 per cent where serious and 100 to 150 per cent where very serious⁵.

Article 191.1 itself excludes from the infringement the cases where the debt “se regularice con arreglo al artículo 27”⁵. In other words, the statute says in as many words that filing on your own initiative is what keeps the penalty away.

A worked example with real numbers

Take the commonest case, which is also the calculator's opening state on this page. An ordinary limited company closes its year on 31 December 2025 and comes out with 20,000 euros to pay.

Its window opens on 1 July 2026 and the statutory 25th is a Saturday, so the last day to file is Monday 27 July 2026. To direct-debit the payment it would have until the 22nd.

The date slips and the return is filed on 27 September 2026. Between 27 July and 27 September there are exactly two complete months, so the surcharge is 1 per cent plus two points, that is 3 per cent: 600 euros. With the article 27.5 reduction it comes down to 450 euros.

Now change one thing. Suppose a demand from the tax agency arrives before the return does. Article 27 stops applying and article 191 opens a penalty of between 10,000 and 30,000 euros on those same 20,000 of tax. The delay is identical in both scenarios. What changes the result, from 450 euros to 10,000 at the very least, is who moved first.

And a third variant. If that same company had closed the year at a loss and its return came out at nil, filing on 27 September would accrue no surcharge at all, because there is no amount payable. It would be a 100 euro fine under article 198, or 60 euros paying promptly.

What this page does not cover

The amount of the tax is not computed here. The rate, the capitalisation reserve, loss relief and the minimum tax are on the Spanish corporation tax calculator and in its explainer article.

The three instalments paid during the year on form 202 are not computed here either, and they are worth reading alongside this page for one concrete reason: the date computed here is exactly what decides which year the April instalment takes as its reference. They are in the form 202 calculator and in Spanish corporation tax payments on account.

Nor does it cover the information return the same company files four months later. Form 232 reports related-party transactions and those involving non-cooperative jurisdictions, settles no tax at all and falls due in the month following the ten months after the close, which is November for a calendar year. They are in the form 232 calculator and in what related-party transactions are.

Nor are late-payment interest figures given in euros. From twelve months on, article 27.2 adds them to the 15 per cent, but the rate is set each year by the Budget Act and the last one approved is the 2023 Act, so this page says which day interest starts running rather than how much it comes to.

Also outside its scope are regional and local holidays, which article 30.6 of Law 39/2015 does take into account⁸ and which are not computed here: only the nine national holidays and Good Friday are. Outside it too are the Basque and Navarrese regimes, which levy their own corporate income tax with their own deadlines, and tax groups, whose form 220 is filed in the individual window of the representative entity.

This page explains the general rules and does not replace advice from a tax adviser on your own circumstances.
