Sunil RaoSweden is a hotbed for tech startups, creative consultants, and freelance specialists. If you decide to transition from standard employment to self-employment, your first major decision is choosing a business structure: a Sole Proprietorship Enskild Firma (sole trader / sole proprietorship) or a Limited Company Aktiebolag (private limited company) / AB.
For 2026, the Swedish government has introduced a major reform to the famous 3:12 rules (fåmansföretagsreglerna), making the corporate tax planning landscape simpler but significantly different. Here is what you need to know.
1. Enskild Firma (Sole Proprietorship)
An Enskild Firma (sole trader / sole proprietorship) is a business form where you, as a private individual, are personally responsible for the company’s agreements, debts, and liabilities. There is no legal separation between you and your business.
Key Features:
- No Startup Capital: It costs nothing in share capital to register.
- Simple Administration: Less paperwork, and no requirement for formal annual reports (årsredovisning) in most cases.
- Taxation Structure: You pay self-employment social fees (egenavgifter) at 28.97% of your business profit (usually calculated on 75% of profits due to the standard schablonavdrag). The remaining profit is taxed as standard personal earned income (municipal tax + state tax if you cross the SEK 643,000 threshold).
2. Aktiebolag (AB - Limited Company)
An Aktiebolag (private limited company) is a separate legal entity. The company’s finances and liabilities are independent of the owner's personal wealth. If the company goes bankrupt, your personal assets are protected (unless you have committed fraud or failed to pay tax debts).
Key Features:
- Startup Capital: Requires a minimum of SEK 25,000 in share capital.
- Double Taxation Benefits: The company pays 20.6% corporate tax on its profit. You can then extract your money in two ways: as a salary (subject to standard social taxes and income taxes) or as a dividend.
- Unified 2026 3:12 Reform: Starting in 2026, the old simplification rule förenklingsregeln (simplified dividend rule) is merged with the salary rule. Owners receive a joint flat-rate base allowance (grundbelopp) of 4 inkomstbasbelopp (IBB) / SEK 322,400 per partner. This amount can be extracted as a dividend taxed at just 20%.
Comparison: Which is better for you?
| Feature | Enskild Firma (sole trader / sole proprietorship) | Aktiebolag (AB) |
|---|---|---|
| Required Capital | SEK 0 | SEK 25,000 |
| Personal Liability | Yes (Unlimited) | No (Limited to share capital) |
| Corporate Tax | N/A (taxed as personal income) | 20.6% on profits |
| Low-tax Dividend (3:12) | No | Yes (up to SEK 322,400 taxed at 20%) |
| Accounting Audit | Never required | Only if exceeding certain sizes |
The "Tipping Point"
If your gross annual revenues are under SEK 500,000, the overhead of managing an AB (yearly accounting, bank account fees, corporate tax filing) usually outweighs the tax benefits. An Enskild Firma (sole trader / sole proprietorship) is much easier to manage.
However, if your annual revenues exceed SEK 600,000 to SEK 800,000, an AB is highly superior. You can pay yourself a salary up to the state tax breakpoint (SEK 55,033/month gross in 2026) to maximize your pension and avoid the 20% state tax surcharge, and then take the rest of your profits out as a 20% taxed dividend, saving you tens of thousands of Kronor in taxes.

Actionable Tip: If you are starting out, use our comparison calculator to simulate your expected revenue. If you are near the SEK 600,000 mark and expect business growth, start with an AB from Day 1 to avoid the administrative friction of converting an Enskild Firma (sole trader / sole proprietorship) later.
