Here we explain what it means and how it affects you as an owner. 4 min read In this guide we cover: - What counts as a closely held company - The main rule and the special rule - What "qualified shares" means - The link to the 3:12 rules and the K10 form (including the new rules from 2026) - How the share register connects to all of this ## What is a closely held company? A company is considered a closely held company if the ownership meets any of the following rules: ## The main rule A limited company or an economic association is a closely held company if four or fewer shareholders own more than half of the voting rights in the company. In other words, it is the voting rights that matter – not just the number of shares. ## The special rule ("de facto control") A company can also be considered a closely held company if there is one person who, in practice, has decisive influence and can dispose of the company's profits – even if the ownership structure on paper appears more widely spread. ## Related parties are counted as one owner When assessing whether a company is closely held, related parties are often aggregated. This means, for example, that spouses/partners, parents, children – and sometimes companies controlled by the family – may be treated as "one ownership group". This means that a company can be closely held even if ownership seems to be spread across more than four people. ## Why does closely held status matter? The label itself isn't what's important – it's what it leads to: special tax rules on dividends and sales, the K10 form as an active owner, and ownership and voting rights must be correctly documented. To calculate correctly under 3:12 and complete K10, you need to know your exact ownership share and voting rights – this is where the share register becomes crucial. ## Qualified shares – the key term in 3:12 Not all shares in a closely held company are automatically covered by 3:12. The rules apply when the shares are qualified. Simply put, shares are qualified if you yourself, or a related party, is active in the company to a significant extent. If the shares are qualified, 3:12 determines how dividends or a sale of shares are taxed. ## The link to 3:12 – and what changes in 2026 The 3:12 rules decide how large a portion of dividends can be taxed as capital income (20% tax) and how large a portion is taxed as salary. From 1 January 2026, a simplified 3:12 system will apply: - One shared calculation model instead of the simplification rule vs. the main rule - A higher standard amount (base amount), but a new 8 IBB deduction in the salary base - The salary-withdrawal requirement is removed, and the 4% restriction is abolished - No annual indexation of saved dividend allowance - Shorter qualifying waiting period for new periods ## Summary of changes If your company is closely held and you are active in it, you should expect that the 3:12 outcome may look different from 2026 (even though the definition of closely held company itself does not change). ## The share register – the prerequisite for calculating correctly The board must keep a share register showing the company's shares and owners, and it must be updated immediately when changes occur. For closely held companies, the share register is especially important because: - 3:12 and K10 are based on ownership and voting rights as of 1 January each year - Ownership shares affect how the dividend allowance is allocated - Ownership changes (new issues, transfers, option exercises, etc.) are common ## Common situations where closely held rules become especially important - Dividends to owners who work in the company - Sale of shares / exit - Entry of new shareholders (e.g., investors or employees) - Ownership via a holding company or in multiple companies - Family-owned companies where related parties affect the closely held assessment ## Short FAQ ### Is my privately owned limited company almost always a closely held company? Yes. If ownership is concentrated to a small group (often family/founders), the company is almost always covered by either the main rule or the special rule. ### Do the 3:12 rules always apply in closely held companies? No – only if your shares are qualified, i.e., you or a related party is active in the company. ### Do I have to file K10 even if I don't take dividends? Under the new rules applying from 2026, the answer is yes, as long as you have qualified shares. ### Why is my family counted together with me? Related parties are treated as one ownership group in closely held assessments in order to reflect real control. ## Summary A closely held company is essentially a company where control lies with a small ownership group. This leads to: - Special rules for dividends and capital gains (3:12) - Annual reporting in K10 - A requirement for a correct and up-to-date share register ## Explore more of eAktiebok [K10 & 3:12 from 2026 How the new rules affect owners. ](/knowledge-bank/k10-312-rules-from-2026)[New 3:12 rules The reform explained in plain language. ](/knowledge-bank/new-312-rules-from-2026)[3:12 rules and your share register What owners must document. ](/blog/312-rules-share-register-2026)[Corporate events Issues, splits and transfers. ](/knowledge-bank/corporate-events)[Transaction list Every ownership change, logged. ](/services/transaction-list)[Corporate law Documents and statutory routines. ](/services/corporate-law)[Create a share register Step-by-step setup guide. ](/register-share-ledger)[Pricing Free, Core and Pro plans compared. ](/pricing) Related reading - [Unlisted Shares in Capital Insurance: 2024 Guide](/blog/unlisted-shares-capital-insurance) Share [](https://www.linkedin.com/sharing/share-offsite/?url=https%3A%2F%2Feaktiebok.lovable.app%2Fkunskapsbank%2Ffamansbolag)[](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Feaktiebok.lovable.app%2Fkunskapsbank%2Ffamansbolag)[](mailto:?subject=Closely%20Held%20Companies%20%E2%80%93%20eAktiebok&body=https%3A%2F%2Feaktiebok.lovable.app%2Fkunskapsbank%2Ffamansbolag) ## Related articles - [ ### Close Corporations – Definition and Why it Matters to You as an Owner What is a close corporation?
