What should K10 appendix contain?
K10 appendix to Inkomstdeklaration 1 shall contain information used to calculate tax on dividends made during the past year and to calculate what scope there is for making dividends for lower taxation for future dividends (so-called low-taxed dividend space).
As a business owner, you can choose to use one of two types of rules for calculating the tax: dividend alternative 1 - the simplification rule or dividend alternative 2 - the main rule. The basic principle is that alternative 1 should be chosen from a tax perspective if you have not made any major salary payments from the company, to yourself and/or any employees. Option 2 should instead be chosen if you have made larger salary payments from the company, to yourself and/or any employees. Note that if you are a partner in several companies, only option 1 can be used for one of these companies and option 2 must be used for the others.
The appendix must be filled in even if no dividend has been paid. For each year that you fill in and submit the appendix, the low-taxed dividend space is calculated and becomes larger and can be used to make dividends from the company to yourself at a lower tax rate.
