I suppose the person means that you have to pay about 50% in taxes to take out the capital/profit from the company before you can use it as a private person.
This type of comparison needs to add corporate income tax (20%) in order to be an apples to apples comparison,so 27.5. It's still a stark difference in taxation, and I know of no other country that does what Finland does for dividend taxation. In fact for earned income,things look even uglier when you add in tax-like social security contributions.
Perhaps not coincidentally, Finnish companies are also an outlier in paying extremely high dividends.
In Norway it's 37.8%. Though you do get "skjermingsrente" (about the same rate as the central bank rate) on the amount you originally invested (ie.: not on any untaxed gains you've had).
