Swedish AB Tax Explained: Corporate Tax, Moms and Salary Rules in 2025

Running a limited company in Sweden means navigating a tax system that is genuinely well-designed but dense with terminology. The headline corporate rate of 20.6% is lower than the UK (25%) or Germany (30%), but once you add moms, arbetsgivaravgifter and the 3:12 rules, the picture becomes considerably more complicated.

This guide walks through every piece of the puzzle: what your AB pays on its profits, how VAT works, the salary versus dividend decision, employer costs, and what you can deduct. There is a full worked example at the end for an AB earning SEK 1,000,000.

Bolagsskatt: the 20.6% corporate income tax

The bolagsskatt is Sweden's corporate income tax. The current rate is 20.6%, applied to the company's taxable profit (beskattningsbar inkomst) for the financial year.

The rate has been falling steadily — it was 26.3% as recently as 2013 — and at 20.6% it is now among the more competitive rates in the EU.

What counts as taxable profit?

Taxable profit starts with accounting profit (the figure on your results statement after all expenses) and then applies a series of adjustments:

• Add back non-deductible costs: fines and penalties, costs associated with prohibited transactions, certain entertainment costs above the allowable threshold.
• Deduct tax-allowable items not in the accounts: accelerated depreciation via the periodiseringsfond (tax allocation reserve) provision, Skattereduktion for research and development.

The most commonly used adjustment is the periodiseringsfond. A company can defer up to 25% of taxable profit each year into this reserve, to be brought back into income within six years. This effectively allows you to smooth profits across years and delay paying bolagsskatt on a chunk of income. The reserve earns a modest interest charge (a percentage of the reserve, set annually by Skatteverket), but for most companies the deferral benefit outweighs the cost.

When and how is bolagsskatt paid?

Sweden operates a preliminary tax (preliminärskatt) system. Your AB makes monthly preliminary payments to Skatteverket based on an estimated profit for the year. After the year end, once you file your inkomstdeklaration, the final figure is settled — either a refund (överskjutande skatt) or a top-up payment (kvarskatt).

The inkomstdeklaration for an AB must be filed within four months of the company's financial year-end. Most Swedish ABs use a calendar-year accounting period (1 January to 31 December), meaning the return is due by 30 April of the following year.

Late filing attracts a penalty of SEK 6,250 for the first reminder, rising to SEK 18,750 for repeated failures. Interest accrues on underpaid preliminary tax at Riksbanken's reference rate plus 15 percentage points.

Moms: Swedish VAT

Moms (mervärdesskatt) is Swedish VAT. Sweden has three rates:

Most ABs deal with the 25% standard rate. If your turnover is above SEK 120,000 per year you must register for moms with Skatteverket. Below that threshold, registration is optional but generally advisable if you have moms-bearing costs to recover.

Filing and payment

Moms is declared on a momsdeklaration, submitted monthly, quarterly, or annually depending on your turnover:

The payment date is the 26th of the month following the period end (the 27th if you file electronically, 17th for some larger filers). Missing the deadline triggers a surcharge (skattetillägg) of 2-10% plus interest.

EU cross-border rules

If your AB sells services to business customers in other EU countries, those supplies are generally zero-rated in Sweden (the customer accounts for VAT in their own country under the reverse charge). Selling to EU consumers (B2C) that exceeds the OSS threshold requires either registering for the One Stop Shop (OSS) or in each relevant country.

The 3:12 rules: how owner-directors take money out

This is the part that confuses almost every foreign founder who sets up in Sweden. The fåmansföretagsregler — usually called the "3:12 rules" after the paragraph of the income tax act they originated from — govern how much dividend a small-company owner can take at the favourable capital income rate versus the higher labour income rate.

The rules exist because Sweden taxes labour income (salary) much more heavily than capital income (dividends). Without a cap, every owner-director would pay themselves the minimum salary and take all profits as dividends. The 3:12 rules prevent this by limiting how much dividend qualifies as capital income.

The two dividend categories

What is the gränsbelopp?

The gränsbelopp is your annual allowance for lågbeskattad utdelning — the amount of dividend you can take at 20%. It is recalculated each year and accumulated if unused.

There are two ways to calculate it. You use whichever is higher:

Method 1: The simplified method (schablonmetoden)

A flat rate applied to the share capital. For 2025: 2.75 times the income base amount (inkomstbasbelopp). The 2025 inkomstbasbelopp is SEK 76,200, so:

Schablonbelopp 2025 = 2.75 × SEK 76,200 = SEK 209,550

This is the maximum annual gränsbelopp available under the simplified method, regardless of how many shares you own (it caps at full ownership).

Method 2: The main method (huvudregeln)

Based on actual salary paid in the company plus third-party employees. The formula for 2025:

Gränsbelopp = (salary base × 50%) + (50% of the owner's own salary above a threshold)

The salary base is calculated as a percentage of total wages paid by the company in the previous year. The percentage is set at 50% of total qualifying wages paid.

For owner-directors in a small company with no other employees, the salary base method produces a larger gränsbelopp only if the owner draws a reasonably high salary — typically at least the "threshold salary" (gränsbelopps­lönen), which for 2025 is approximately SEK 459,960 per year (6 × income base amount + SEK 100,000).

Most small AB owners use the schablonmetoden because they either do not pay themselves enough to trigger the salary base advantage or simply want certainty.

Unused gränsbelopp carries forward

If you do not take the full gränsbelopp as dividend in a given year, the unused portion accumulates with interest (statslåneräntan + 3%, which in 2025 is approximately 5.94%). This can build up significantly over time and is worth tracking carefully.

The mandatory salary requirement

To benefit from the 3:12 rules at all, you must pay yourself a salary that meets the minimum wage requirement (lönevillkoret). For 2025, the threshold is the lower of:

• 9.6 × the income base amount = SEK 731,520, or
• 6 × the income base amount + SEK 100,000 = SEK 557,200

In practice, most owner-directors aim to pay themselves a salary of around SEK 50,000–60,000 per month (SEK 600,000–720,000 annually) to satisfy the minimum and trigger the salary base calculation for the following year's gränsbelopp.

Example 3:12 calculation

Assume Anna owns 100% of her AB, paid herself SEK 600,000 salary in 2024, and the company pays SEK 50,000 salary to a part-time employee.

Total wages paid in 2024: SEK 650,000.

For 2025 gränsbelopp using the main method:

Salary base: 50% × SEK 650,000 = SEK 325,000

Owner's excess salary: SEK 600,000 - SEK 459,960 = SEK 140,040 × 50% = SEK 70,020

Total gränsbelopp 2025: SEK 325,000 + SEK 70,020 = SEK 395,020

Using the schablonmetoden: SEK 209,550.

Anna uses the main method (SEK 395,020 > SEK 209,550). She can take up to SEK 395,020 as dividend in 2025 at the 20% capital income rate.

Arbetsgivaravgifter: employer social charges

When your AB pays you a salary, it must also pay arbetsgivaravgifter — employer social contributions. The standard rate is 31.42% of gross salary.

So for every SEK 100 of gross salary you pay yourself, the total cost to the company is SEK 131.42.

Reduced rates

A reduced rate of 10.21% (only the pension contribution) applies to employees aged 66 or over. For employees aged 15-18, lower rates apply.

For sole traders and partners in handelsbolag (partnerships), the equivalent charge is egenavgifter, structured differently but broadly similar in total cost.

Employee income tax

On top of the arbetsgivaravgifter, the employee (you, as director-owner) pays:

• Kommunalskatt (municipal income tax): varies by municipality, typically 29–33%. Stockholm municipality is 29.83%.
• Statlig inkomstskatt (national income tax): 20% on the portion of income exceeding the threshold (SEK 643,100 in 2025).

This means salary above the threshold is taxed at approximately 52–53% (local + national), before considering jobbskatteavdraget (the earned income tax credit), which partially offsets this at lower income levels.

Deductible expenses for a Swedish AB

Your AB can deduct business expenses in calculating taxable profit. Sweden's rules broadly follow the principle that costs must be incurred "for the business" (i bolagets verksamhet) to be deductible.

Fully deductible

• Rent and premises: office rent, utility costs attributable to business space.
• Salaries and employer charges: gross salary plus arbetsgivaravgifter for all employees.
• Equipment and technology: computers, phones, software subscriptions — fully deductible when the useful life is three years or less; otherwise capitalised and depreciated.
• Professional development: courses, conferences, subscriptions to professional publications relevant to the business.
• Travel: flights, trains, hotels for genuine business travel. Mileage for business use of own vehicle at the Skatteverket-approved rate (SEK 25 per kilometre in 2025 for most vehicles).
• Marketing and advertising: website costs, advertising, agency fees.
• Accountant, lawyer, bookkeeper fees: fully deductible professional fees.
• Bank charges: transaction fees, account charges.
• Pension contributions: contributions to an occupational pension (tjänstepension) for yourself and employees, within limits (roughly 35% of salary, up to a ceiling).

Partly deductible or restricted

• Entertainment (representation): costs of entertaining clients are deductible but tightly capped. Business meals: SEK 300 per person excluding moms (reduced from SEK 90 in 2017 to this figure through subsequent changes — verify the current cap with Skatteverket). Customer events: deductible but subject to reasonableness. The moms deduction on entertainment is more restricted than the cost deduction.
• Home office: if you work from home, a portion of rent/mortgage interest is deductible, but the calculation is prescriptive. The simplest approach is to use a rented office or co-working space instead.
• Car: company-owned cars create a benefit-in-kind (bilförmån) for the director, which is taxable income to you and triggers employer charges. Leased vehicles follow the same treatment.
• Company phone: a company phone is tax-free to the employee provided it is primarily used for business and the employer does not restrict private use.

Non-deductible

• Tax penalties and surcharges (skattetillägg).
• Fines (böter).
• Dividends paid to shareholders.
• Costs that are personal in nature, even if paid through the company.

Skatteverket: filing and key dates

Sweden's tax authority is Skatteverket (skatteverket.se). All company filings are submitted digitally.

Missing the inkomstdeklaration deadline costs SEK 6,250 (first reminder) rising to SEK 18,750. Errors in VAT returns that result in underpayment attract skattetillägg of 20% of the underpaid tax.

New rules for 2025

The most significant recent change is the CESOP reporting obligation for payment service providers (PSPs) — relevant to ABs that facilitate third-party payments. For most trading ABs, the key 2025 update is the continued reduction in periodiseringsfond interest costs and minor adjustments to the lönekostnaderna threshold for the 3:12 gränsbelopp calculation.

Worked example: SEK 1,000,000 AB profit

Let us run through the full picture for a Swedish AB with SEK 1,000,000 in annual profit before salary.

Assumptions:

• One owner-director, 100% shareholder, no other employees.
• Uses schablonmetoden for the 3:12 gränsbelopp.
• Stockholm municipality (kommunalskatt 29.83%).
• Owner takes SEK 560,000 gross salary (satisfies the lönevillkor threshold for gränsbelopp purposes).

Step 1: Company profit and bolagsskatt

The company retains SEK 157,241 after bolagsskatt, available to distribute as dividend.

Step 2: Owner's income tax on salary

(These figures are approximate; the exact jobbskatteavdrag requires the Skatteverket calculator at skatteverket.se.)

Step 3: Dividend at 20% (within gränsbelopp)

Because the dividend is within the gränsbelopp, it is taxed at 20%. The unused gränsbelopp of SEK 52,309 carries forward to 2026 with interest.

Step 4: Total tax summary

For comparison, a UK company director extracting similar income would typically face a blended effective rate of 35–42% depending on salary/dividend split. Sweden's headline "high tax" reputation is partially offset by the structured optionality of the 3:12 rules and the relatively low bolagsskatt.

Common mistakes Swedish AB owners make

Taking too much salary. Salary above the statlig skatt threshold (SEK 643,100) is taxed at 52–53% effective. Below that level, salary is efficient. Many founders accidentally push themselves into the higher band when a dividend would have been taxed at 20%.

Ignoring the gränsbelopp accumulation. The unused gränsbelopp carries forward each year. Founders who have been in business for several years often have a large accumulated gränsbelopp they do not realise they can use. Run the calculation before declaring a dividend each year.

Missing the schablonmetod versus huvudregel decision. If your company employs other people, the main method almost always produces a higher gränsbelopp. Many founder-owners default to the schablonmetod without checking.

Failing to register for moms. If your AB passes SEK 120,000 turnover, moms registration is mandatory. Late registration does not retroactively exempt you — Skatteverket can assess moms from the date the threshold was exceeded.

Keeping the periodiseringsfond indefinitely. Funds must be released within six years. If your company has a very high profit year and then a loss year, releasing the reserve in the loss year can mean it is largely offset. Plan the release deliberately.

Mixing personal and business expenses. Skatteverket audits AB accounts with more scrutiny than sole traders. Unexplained transfers to the owner's personal account are treated as income and subject to full income tax and employer charges.

Frequently asked questions

What is the corporate tax rate for a Swedish AB in 2025? 20.6% on taxable profit (beskattningsbar inkomst) after allowable deductions.

How much can I take as a dividend at the low 20% rate? Up to your annual gränsbelopp. Under the simplified method (schablonmetoden), this is SEK 209,550 for 2025. The main method can produce a higher allowance if you pay sufficient salary to yourself and other employees.

Do I have to pay myself a salary from my AB? No legal minimum salary rule exists, but to benefit from the 3:12 rules and take dividends at 20%, you must satisfy the minimum salary threshold (lönevillkoret). For 2025, this is approximately SEK 557,200.

What is the moms rate in Sweden? The standard rate is 25%. Food, hotels and restaurant meals are taxed at 12%. Books, passenger transport and some cultural services at 6%. Exports and medical services are zero-rated.

How do I pay corporate tax in Sweden? Through monthly preliminary tax payments (preliminärskatt) to Skatteverket, with a final settlement when you file the inkomstdeklaration within four months of your year-end.

Can I defer some of my company profit to reduce the tax bill? Yes — through the periodiseringsfond (tax allocation reserve), your AB can defer up to 25% of taxable profit each year for up to six years. This is one of the most effective legal tax planning tools available to Swedish companies.

What is the difference between lågbeskattad utdelning and överskottsdividend? Lågbeskattad utdelning is dividend within your gränsbelopp, taxed at 20% as capital income. Överskottsdividend is dividend above the gränsbelopp, taxed as salary income (at your marginal rate of 32–52%), with the excess treated as labour income.

Do I need to file a separate employer return if I am the only employee? Yes. Every month you pay salary, you must file an arbetsgivardeklaration with Skatteverket by the 12th of the following month, reporting the gross salary and calculated arbetsgivaravgifter.

What happens if my AB makes a loss? Losses can be carried forward indefinitely and offset against future profits. There is no carry-back provision in Sweden (unlike the UK). A loss year also allows you to release periodiseringsfond reserves with reduced net tax cost, since the released amount is partly offset by the current year's loss.

Is the corporate tax rate in Sweden likely to change? Sweden has been gradually reducing bolagsskatt (from 28% in 2009 to 20.6% today). No rate change is scheduled for 2025 or 2026, but monitor Skatteverket and Finansdepartementet for budget announcements each autumn.
