Frequently asked questions about bookkeeping
What is the difference between single-entry and double-entry bookkeeping?
Single-entry bookkeeping is cash-based: income and expenses are recorded when the money actually moves. It is enough for most sole traders. Double-entry bookkeeping is more comprehensive: every business transaction is entered in two accounts (debit and credit).
When does a sole trader have to move to double-entry bookkeeping?
When at least two of these limits are exceeded in two consecutive financial periods: a balance sheet total over €100,000, turnover over €200,000 or an average of more than 3 employees.
How long do I have to keep bookkeeping vouchers?
Vouchers such as invoices, receipts and bank statements must be kept for at least 6 years from the end of the financial period. Financial statements and other bookkeeping records may have to be kept for up to 10 years.
Is bookkeeping mandatory for a sole trader?
Yes. The Finnish Accounting Act requires everyone who carries on business to keep books, sole traders included.
Can I do my bookkeeping without software?
Yes, for example in Excel. Bookkeeping software like Kletta still makes the work much easier: invoicing, VAT calculation, tax returns and real-time tracking cut mistakes and save time.
Can I deduct the costs of a work space?
Yes. A sole trader can deduct the costs of a work space, such as rent and electricity, if the space is used mainly for business. You can find more in the Tax Administration’s guidance.
When does a sole trader have to prepare financial statements?
Usually you don’t have to. Financial statements are mandatory only if the financial period differs from the calendar year, or if two of the limits are exceeded in two consecutive financial periods (for example a balance sheet of €350,000, turnover of €700,000 or more than 10 employees).
