Closely Held Companies – What They Are and Why They Matter in 2026

Most privately owned limited companies in Sweden are considered closely held companies. Here we explain what it means and how it affects you as an owner.

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

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
