What the K10 form means for you as an owner
For you as an owner, the K10 form is decisive for how tax-efficient your dividend or sale turns out to be. A correctly completed form ensures that the right part is taxed as capital income and that any saved dividend allowance is not lost.
Errors or failing to submit the form can lead to higher taxation than necessary. It is therefore important to understand how the form works and which details must be reported.
Details normally reported in the K10
The K10 form contains several key parts that affect taxation.
- Ownership stake and holding period in the company
- Calculation of the threshold amount under the chosen rule
- Dividends taken during the year
- Saved dividend allowance from previous years
- Capital gains on the sale of shares
When these details are filled in correctly, they provide a clear basis for correct taxation under the 3:12 rules.
When the K10 form must be submitted
Worth bearing in mind
The K10 form must be submitted by anyone who owns qualified shares in a close company, whether or not they have taken a dividend during the year. The form is used to calculate the threshold amount and to save dividend allowance for future years.
The K10 is also necessary when shares in a close company are sold, as it determines how the capital gain is divided between taxation as capital income and as employment income.
