French-speaking families who keep a Luxembourg SOPARFI, a trust, or an insurance wrapper on a Belgian-resident founder\u2019s chart still need a Belgian Cayman tax look-through<\/strong> analysis. The nickname is journalistic. The statute is look-through taxation of \u201cconstructions juridiques\u201d in the Belgian Income Tax Code 1992. It is not a special offshore tariff, and this article does not invent one. Income of a targeted construction is, as a rule, taxed in the founder\u2019s hands as if the founder had received it. Declaration duties sit beside the tax itself.<\/p>\n

This article is general information for families and family offices. It is not a Belgian tax opinion, a mandate, or personalised advice. Whether a vehicle is a construction, whether a substance exclusion applies, and how a treaty interacts depend on the facts and on Belgian counsel who can read the CIR 92 articles and the SPF Finances forms.<\/p>\n

Belgian Cayman tax look-through is a transparency rule<\/h2>\n

Belgium introduced the regime in 2015 and has widened it since. The working pieces live in article 2, \u00a71, 13\u00b0 (definition of a construction juridique), article 2, \u00a71, 14\u00b0 (founder), article 5\/1 (look-through for individuals), article 220\/1 (look-through for certain legal persons), and article 307 (declaration). Distributions and other advantages can also be taxed. The SPF Finances still treats the regime as a transparency tax, which is why French-speaking practice says taxe Ca\u00efman or taxe de transparence in the same breath.<\/p>\n

The administration\u2019s filing instructions are public. The SPF Finances portal<\/a> carries the income-tax materials. The annex for constructions, form 276 CJC, has its own official 276 CJC explanations<\/a>. From assessment year 2024 the annex is mandatory for each construction mentioned in the return. The consolidated CIR 92 is on the Belgian statute site via eJustice<\/a>. Circular 2024\/C\/79 of 11 December 2024 states the administration\u2019s view of the regime when the construction sits in a treaty country. Families should read that circular as an administrative position, not as a substitute for the code or for case law.<\/p>\n

Look-through means the Belgian resident is taxed on the construction\u2019s income according to Belgian income-tax categories, not according to a made-up Cayman percentage. If the construction earns interest, the founder\u2019s return follows the interest rules. If it earns dividends or a capital gain, those categories apply. This article does not restate Belgian personal rates. They are progressive, they change, and they belong on the SPF pages for the year, not in a family-office slogan.<\/p>\n

What counts as a construction juridique<\/h2>\n

A construction juridique is not \u201canything foreign.\u201d Article 2, \u00a71, 13\u00b0 covers, in substance, two families of vehicles. First, arrangements without legal personality that hold assets for the founder or beneficiaries, the trust and foundation pattern. Second, legal persons established in a jurisdiction with a tax regime that the Belgian lists or tests treat as low or non-existent, when the founder holds a sufficient interest. The statute and royal decrees, not a dinner-table list of \u201ctax havens,\u201d decide which companies are in.<\/p>\n

In French-speaking files the vehicles that actually appear are familiar. A Luxembourg SOPARFI can be a construction if it fails the Belgian tests, including when it is a holding with little tax in Luxembourg. A Maltese or Cypriot holding, a Jersey or Cayman company, a Delaware LLC used as a wrapper, a Liechtenstein foundation, and a trust of any proper-law are the usual suspects. A French SCI that only holds a personal-use dwelling can also fall in, depending on the facts, which is why \u201cit is European\u201d is not an exclusion. Article 2, \u00a71, 13\u00b0\/1 then carves out vehicles that are deemed not to be constructions, including some that meet a substance or listing condition. The carve-out is a legal test. It is not a branding exercise.<\/p>\n

Substance exclusion and treaties<\/h3>\n

When the construction is established in a State with which Belgium has a double-tax convention, the code already excludes look-through if the construction\u2019s income is mainly derived from genuine economic activities. That is the substance gate. A Luxembourg company with people, premises, and a real business is in a different conversation from a SOPARFI that only holds a securities portfolio. Circular 2024\/C\/79 adds the administration\u2019s view that, where look-through still applies, treaties do not block Belgian tax on the founder because the double tax would be economic (two taxpayers) rather than juridical (one taxpayer taxed twice). Courts can disagree. A Leuven judgment in 2025, reported in Belgian professional writing, treated a Hong Kong convention as blocking look-through on business profits. This article records the conflict. It does not pick a winner. Families should not plan as if the circular were a statute, or as if one court were the last word.<\/p>\n

Luxembourg wrappers and insurance envelopes<\/h2>\n

French-speaking families often sit on both sides of the border: a Belgian household, a French operating history, a Luxembourg holding, sometimes a Luxembourg assurance-vie. Cayman tax is a Belgian-resident\u2019s problem. A French-resident founder is not in article 5\/1 because of a Belgian nickname. A Belgian-resident founder of a Luxembourg SOPARFI is. Moving the founder\u2019s tax residence without moving the construction, or the reverse, changes the file. French IFI look-through of real-estate companies, discussed in the IFI 2026 taxable-wealth inventory<\/a>, is a different levy in a different country. The same SOPARFI can be an IFI look-through problem for a French resident and a Cayman look-through problem for a Belgian resident.<\/p>\n

Insurance wrappers are not automatically outside. A contract can be a construction or can sit on top of one. Belgian tax on life-insurance proceeds has its own articles. Cayman tax asks whether a legal construction sits underneath. Treating \u201cLuxembourg life\u201d as a synonym for \u201cnot a construction\u201d is how families discover an annex 276 CJC conversation after the return is filed. The work is to identify the founder, the vehicle, the income, and the exclusion tests, not to hide the vehicle behind a policy number.<\/p>\n

Trusts, foundations, and the founder definition<\/h2>\n

The founder definition is wide. It is not limited to the person who signed the trust deed. Persons who transferred assets, persons who can be equated with the economic settlor, and in some cases heirs, can be founders. A beneficiary who receives a dividend or any other advantage from a construction has declaration duties even if counsel argues that look-through tax sits on someone else. Annex 276 CJC is built for that dual track: identification of the construction, income taken into the return under look-through, and income distributed.<\/p>\n

Opaque chains do not help. A trust that owns a BVI company that owns a Luxembourg holding is still a chart to unroll. Each layer can be a construction. The SPF form is per construction. Skipping a layer because it \u201conly holds shares\u201d is the usual miss. Holding-company interest limitation under ATAD in 2026<\/a> is a corporate-tax ceiling in another chapter. It does not switch Cayman tax off.<\/p>\n

Declaration is not optional hygiene<\/h2>\n

Article 307 CIR 92 requires the founder, and certain recipients of advantages, to tick the construction box and to attach 276 CJC. Failure to declare is a separate problem from the tax on the income. Belgian procedure imposes specific penalties for omitted constructions. This article does not convert those penalties into a planning budget. It records that the SPF built a dedicated annex because the old line in the return was not enough to follow the tax.<\/p>\n

A useful family-office inventory is dull. List every non-Belgian vehicle and every trust or foundation. Flag who is Belgian-resident among founders and beneficiaries. Flag Luxembourg holdings, insurance envelopes, and French SCIs. Obtain the construction\u2019s accounts or trustee pack so that Belgian income categories can be applied. Note any substance file that would support the treaty-country exclusion. Note any distribution in the year. Then let Belgian counsel complete 276 CJC. Vellum Finance does not file Belgian returns. The Vellum Finance services<\/a> model is fee-only coordination of the chart so that the Belgian adviser is not reconstructing a SOPARFI from memory in June.<\/p>\n

Cross-border French-Belgian households need two residence answers before they need a Cayman answer. A founder who is French-resident is in the French CFC, trust, and IFI chapters, not in article 5\/1 CIR 92. A founder who is Belgian-resident is in Cayman tax even if the operating history, the language of the family, and the notary are French. Dual claims are a treaty file. They are not a reason to leave the SOPARFI off 276 CJC \u201cbecause we already declare in France.\u201d Belgium\u2019s look-through and France\u2019s look-through are not a single European form. They are two administrations, two definitions of a targeted vehicle, and two calendars.<\/p>\n

Conclusion<\/h2>\n

Belgian Cayman tax is look-through of legal constructions in the CIR 92, plus a declaration on annex 276 CJC. It is not a special rate. Luxembourg holdings, trusts, foundations, and some insurance stacks can be in scope for a Belgian-resident founder. Substance in a treaty country can exclude the tax. Circular 2024\/C\/79 and recent case law do not yet tell a single story on treaties. Read the SPF pages, list the constructions, and let Belgian counsel apply articles 2, 5\/1, and 307. Do not treat a French-speaking family name as a substitute for a Belgian residence analysis.<\/p>\n
