Bookkeeping for a sole trader — how it works in practice.

Who is a sole trader right for?

A sole trader (enskild firma) is Sweden's simplest business structure: fast to start, light on admin, and no start-up capital required. The downside is that the business isn't a separate legal entity — you're personally liable for its debts. This structure suits freelancers, consultants, tradespeople and other solo business owners, especially in the early stages.

Bookkeeping duty — what do the rules say?

Everyone running a business is required to keep accounts. That means ongoing bookkeeping with a supporting document for every business transaction, and keeping your accounting records for at least 7 years. If the company's turnover is under 3 million kronor, you can prepare simplified year-end accounts — a smoother, less extensive version than full year-end accounts.

Cash basis or invoice basis?

Smaller businesses (with a turnover under 3 million kronor) can use the cash basis: you record transactions when the money actually moves, not when the invoice is sent. It's a simpler system and enough for most solo business owners.

The invoice basis, on the other hand, gives better control over receivables and payables as the business grows. Transactions are recorded when they occur — even if payment comes later — which gives a more current and accurate picture of the company's finances.

VAT for a sole trader

Do you need to register for VAT?

As a business owner, you need to decide whether to be VAT-registered. For smaller businesses, since 2025 there is a turnover threshold of 120 000 kronor a year that decides whether registration is mandatory or voluntary.

If your turnover is above the threshold, you must register for VAT. Below it, you can choose VAT exemption — but voluntary registration often pays off, since it lets you deduct input VAT on your purchases. Still finding this hard to follow? Read the full VAT guide here.

Year-end accounts — NE-bilagan

Your business's result is declared in the NE-bilagan (the sole trader's tax return annex) attached to your personal tax return. The simplified year-end accounts are the basis for it. There's money to be gained here if you get it right: deductions for a home office, business travel, tools and pension savings are common opportunities that are often missed through lack of knowledge.

When does it pay to get help with bookkeeping?

What decides when it's worth getting help isn't how many transactions you have, but how confident you are with the rules. Bookkeeping for a sole trader requires a good grasp of deductions, taxation, VAT and how everything is reported in the NE-bilagan. If you have the knowledge and a knack for staying organised, you can handle the bookkeeping yourself with a modern accounting program.

It pays to get help when any of this applies: you're unsure about the deduction rules, you're VAT-registered and want to avoid mistakes, the business is growing, you invoice abroad, you spend more time on admin than on your customers — or you want to be sure nothing important slips through.
