Because your company earned the income, only the company paid tax on it.
If you transfer 6,000 EUR to your personal account then you need to either:
1. Consider it as new personal income, which is taxable - your company's tax bill has no connection to your's.
2. Consider it as a repayment of a prior payment made to the company. I assume you paid a significant amount to the company at the start to purchase the apartments. In this scenario, it is not taxable as it is a repayment of a 'loan' you made to the company.
