| When | What | Good to know |
|---|---|---|
| Every week or month | Record all transactions (löpande bokföring) | Cash transactions by the next working day, others as soon as possible. Keep a voucher (verifikation) for every entry. |
| Every month | Pay preliminary tax (F-skatt) to the tax account | Normally by the 12th of each month (17th in January and August). The amount comes from your preliminary tax decision. |
| Every quarter | VAT return (momsdeklaration) | Q1 by 12 May, Q2 by 17 August, Q3 by 12 November and Q4 by 12 February. |
| 31 December | Financial year ends – start the year-end closing (bokslut) | Count stock and cash, reconcile bank and tax account, book accruals and depreciation. |
| By 30 June | Annual general meeting (årsstämma) adopts the annual report | Within six months after the end of the financial year. |
| By 31 July | Annual report (årsredovisning) to Bolagsverket | Within seven months after the end of the financial year. Late filing gives a late-filing fee. |
| After the year-end | Income tax return for the company (INK2) | The date depends on when the financial year ends – for a calendar year it is in the summer. Check Skatteverket’s calendar. |
| Always | Keep the accounting records for seven years | Seven years after the end of the calendar year in which the financial year ended. Digital storage is fine. |
Typical deadlines for small companies (turnover up to SEK 40 million). Exact dates can move when they fall on a weekend – always check Skatteverket’s calendar. In UNIKBOK you get these reports from your bookkeeping.
The main bookkeeping rules in Sweden
| Rule | What it means |
|---|---|
| Bookkeeping Act (bokföringslagen)Read more → | The law that decides who must keep books, how and for how long. All companies – sole traders, limited companies and partnerships – are covered. |
| Generally accepted accounting principles (god redovisningssed) | Set out mainly in the guidance of the Swedish Accounting Standards Board (Bokföringsnämnden, BFN). |
| K1, K2 and K3Read more → | Rule sets for the year-end. K1 for smaller sole traders (simplified annual accounts), K2 for smaller limited companies, K3 as the main framework. |
| BAS chart of accountsRead more → | The standard Swedish chart of accounts. Account 1930 is the business bank account, 2641 is input VAT, 3001 is sales at 25 % VAT. |
| Vouchers (verifikationer)Read more → | Every entry needs a voucher with date, amount, what it concerns and the counterparty. Errors are corrected – never deleted. |
| Seven-year archiving | Accounting records are kept for seven years, digitally or on paper. |
| SIE files | The Swedish standard file format for moving bookkeeping between programs and accountants. |
Who must keep books in Sweden?
Everyone who runs a business in Sweden is required to keep books (bokföringsskyldig): sole traders (enskild firma), limited companies (aktiebolag), trading partnerships (handelsbolag) and economic associations. Non-profit associations are covered when they run a business or have large assets.
The responsibility always stays with the company – in a limited company with the board and managing director, in a sole trader business with the owner. You can hire an accountant to do the work, but not to take over the responsibility.
VAT in Sweden (moms)
Most companies must register for VAT. The standard rate is 25 %, with reduced rates of 12 % and 6 % for certain goods and services – check which rate applies to what you sell.
How often you file depends on your turnover: once a year if taxable sales are at most SEK 1 million, quarterly up to SEK 40 million and monthly above that (you can choose monthly voluntarily). Services bought from other EU countries usually follow the reverse charge rules, which means you report both output and input VAT yourself.
Payroll and the employer declaration (AGI)
When you pay salaries – also to yourself in a limited company – you withhold preliminary income tax and pay employer contributions (arbetsgivaravgifter) of 31.42 % for most employees in 2026. Both are reported every month in the employer declaration (arbetsgivardeklaration, AGI) at individual level.

Year-end: annual accounts and tax returns
Sole traders with a net turnover normally below SEK 3 million may prepare simplified annual accounts (förenklat årsbokslut, K1) and report the result on the NE appendix of their personal income tax return.
A limited company always prepares an annual report (årsredovisning) under K2 or K3. It is adopted at the annual general meeting and filed with the Swedish Companies Registration Office (Bolagsverket) within seven months after the end of the financial year. The company files its own income tax return (INK2).

Sole trader or limited company?
The choice of company form decides much of your bookkeeping: a sole trader is taxed personally and can use simplified annual accounts, while a limited company is a separate legal person with its own tax return and annual report. To invoice as a business you normally need F-tax approval (F-skatt).

Do it yourself or hire an accountant?
Many small business owners in Sweden do their own bookkeeping with a good program and get help with the year-end the first year. An accounting firm often charges SEK 500–800 per hour, so doing the day-to-day bookkeeping yourself can save a lot – as long as you keep it up to date.
