Digest · Issue 04 · week in review

A quiet week in Spain, and four December deadlines that are not.

Updated

Almost nothing of consequence reached the gazette between 23 and 29 September. Rather than pad the issue, we have used it to set out what lands in the last month of the year, because three of the four need work started now and one of them is a valuation date you cannot fix afterwards.

Every item below says who it touches, what to do and where it came from. Filter by topic, or switch on only items needing action to skip the context.
This was a thin week and we would rather say so. The Spanish gazette carried a convalidation, three narrow social security decrees and a carbon tax form change. The Council of Ministers announced an energy package on Tuesday whose instrument had not been published when this issue closed. So the substance below is the December map, assembled from the instruments themselves.
01
ImmigrationWindow closes 6 October 2026Act now

The immigration consultation window has seven days left

The two draft bills we flagged last week remain open for public comment: the amendment to Organic Law 4/2000 on the rights and freedoms of foreign nationals, and the new Asylum Law. The Ministry of the Interior opened the audiencia e informacion publica from 23 September to 6 October 2026. Nothing has changed in the law in force; what closes is the chance to say anything about it.

Who this touchesAny company that hires non-EU staff or moves people to Spain, and anyone whose route depends on current immigration procedure.
This is the last full week to submit. After 6 October the texts move to the next stage without your input, and the next opportunity is the parliamentary one, where individual businesses have far less traction.

AI and tech2 December 2026Diarise

The AI Act obligations that did not move to 2027

The Digital Omnibus on AI was published in the Official Journal on 24 July 2026 and entered into force on 27 July. It deferred the high-risk obligations for standalone Annex III systems from 2 August 2026 to 2 December 2027, and for AI embedded in products covered by EU product safety law to 2 August 2028. Two things land on 2 December 2026 instead: the machine-readable marking duty in article 50(2) for systems already on the market at 2 August 2026, and two new prohibitions added to article 5. The transparency duties in article 50 have applied since 2 August 2026 and the general-purpose model obligations in articles 51 to 56 since August 2025; neither was touched.

Who this touchesAnyone placing an AI system on the EU market, and in particular anyone who read the headline about a delay and concluded that nothing applies until 2027.
If you deferred work on the strength of the Omnibus, separate the parts that moved from the parts that did not. Marking of generated content is an engineering change with a lead time, not a policy document.

Company and market access9 December 2026Diarise

Product liability: the new directive replaces a forty-year-old regime

Directive (EU) 2024/2853 has to be transposed by 9 December 2026. It applies to products placed on the market or put into service after that date, and Directive 85/374/EEC is repealed with effect from the same day while continuing to govern products placed on the market before it. The new regime extends the chain of liable economic operators and adapts the rules to software, digital products and AI.

Who this touchesAnyone who manufactures, imports or acts as an authorised representative for products sold in the EU. The representative role sits inside the chain of economic operators, which is the part most people have not priced.
Diarise the date, and separate your product portfolio into what will have been placed on the market before 9 December and what will come after. The old directive keeps applying to the first group, so for a while you are running two regimes.
04
Company and market access30 December 2026Diarise

The deforestation regulation applies, after a second delay

Regulation (EU) 2025/2650 of 19 December 2025 amended the EUDR again. It now applies from 30 December 2026 for medium and large operators and traders, with micro and small enterprises given until June 2027. The delay came with simplification of the reporting obligations rather than a change of substance.

Who this touchesAnyone placing cattle, cocoa, coffee, palm oil, rubber, soya or wood, or products derived from them, on the EU market. The list catches more packaging and furniture than businesses expect.
If you dismissed this when it was postponed the first time, the second postponement is the last one anybody is planning for. Due diligence statements need supply-chain data that takes months to collect.
05
Tax31 December 2026Act now

Wealth tax and the solidarity tax are measured on 31 December

Both taxes accrue on 31 December each year and attach to the net worth held on that date. The solidarity tax reaches net wealth above three million euro, allows a deduction only for wealth tax actually paid, and was extended indefinitely by Real Decreto-ley 8/2023 pending a review of wealth taxation. Six regions have since recast their wealth tax relief by reference to it.

Who this touchesAnyone tax resident in Spain with substantial assets, and anyone arriving before the end of the year who has not looked at what they will own on 31 December.
This is the one date on the list that cannot be worked on afterwards. Whatever the balance sheet looks like on 31 December is the base, so anything to be changed has to be changed in the next three months.
06
Tax1 January 2027Diarise

Verifactu becomes mandatory for companies, and the B2B clock has still not started

Verifactu applies to companies subject to corporate income tax from 1 January 2027 and to the self-employed from 1 July 2027, on the timetable set by article 3 of Real Decreto-ley 15/2025 of 2 December, which amended the fourth final provision of Real Decreto 1007/2023. It is a separate obligation from B2B electronic invoicing, which comes from Real Decreto 238/2026 and whose phased periods only begin once the ministerial order approving the public invoicing solution is published. That order has not appeared. Dates circulating for the B2B tiers are expectations rather than law.

Who this touchesEvery Spanish company, and every foreign group with a Spanish subsidiary that issues invoices from local software.
Ask your software provider for its Verifactu certification position now rather than in December. On the B2B side, do not commit budget to a date the instrument does not yet give.
07
Tax23 September 2026No action

Congress convalidated the La Palma decree-law

A resolution of the Congress of Deputies of 23 September ordered publication of the convalidation of Real Decreto-ley 23/2026 of 8 September, which adopts urgent fiscal and financial measures for the economic and social reconstruction of La Palma and measures to promote investment by autonomous communities holding budget surpluses and unapplied financing from years before 2026.

Who this touchesBusinesses on La Palma, and regional administrations with surpluses to deploy.
Nothing unless you operate on the island. Included because it is the substantive thing the gazette carried this week.
08
Company and market accessWeek of 29 September 2026No action

An energy package was announced but has not been published

The Council of Ministers of 29 September announced a package intended to contain increases in energy bills. At the time this issue closed the instrument had not reached the gazette, so its scope, its beneficiaries and its dates are not yet established. We are not going to summarise a press conference as if it were a decree.

Who this touchesEnergy-intensive operations in Spain, potentially.
Nothing yet. We will carry it next week with the instrument reference once it is published.
Each item links to its source. We summarise; we do not replace the official text, and Spanish implementation dates have moved more than once. Nothing here is legal or tax advice for your situation.

Four deadlines in one month and one of them is a valuation date.
