The annual tax return (Tax Return Form 5) is the yearly tax declaration for sole traders, where the company’s income, expenses, and result are reported to the Finnish Tax Administration. Based on this information, the amount of tax payable from business activities is calculated.
The tax return is submitted after the end of the financial year, usually in the spring. Form 5 is based on the company’s bookkeeping, so its accuracy depends on the bookkeeping being up to date and correctly prepared.
At Corosar, we make sure the form is completed with the correct information, submitted on time, and that any additional income or special situations are properly taken into account. You don’t need to guess what should be reported or where – we go through everything with you clearly and in an easy-to-understand way.
