First of all, you have to decide whether the company you want to establish will be a sole proprietorship or a capital company. For this, the most important issue will be to evaluate the tax brackets and evaluate the partnership structure.
For example, while there is an increasing taxation rate in private companies, there is a flat rate profit tax in capital companies (joint stock, limited) even though it changes every year (like 22-23-25).
In sole proprietorships, the profit taxation situation is generally as follows:
| 0-32.000 TL | %15 |
| 32.000-70.000 TL | 4,800 TL + 20% for the part over 32,000 |
| 70.000-170.000 TL | 12,400 TL + 27% for the part over 70,000 |
| 170.000 TL-880.000 TL | 39,400 TL + 35% for the part over 170,000 |
| + 880.000 TL | 287,900 TL + 40% for the part over 880,000 |
Secondly, you should determine what the main activity of your company is. Your company will operate primarily in one area, but other activities will be subject to additional activity. Your main activity will affect your NACE code and will appear in your activity document. For example, when you give your activity certificate to a bank, they will recognize you with this main activity. Identifying activities other than the main activity is also important in the following sense: all the work you will do under the purpose subject clause in your company’s main contract must be passed. It will be to your advantage to include the jobs that you are likely to do in the future to this section.
Thirdly, profit sharing can be made, partnership can be established, manager can be appointed in capital companies, but this cannot be the case in private companies.
