The question of whether a sole proprietorship or a limited liability company is more advantageous from a tax standpoint depends on your profit level, risk profile, and future plans. For lower profit levels, a sole proprietorship is often more appealing, because of the many deductions on offer, including, e.g. the deduction for self-employed professionals, and SME profit exemption.
As profits increase, a private limited company may become the better option, because you then benefit from a lower corporate income tax rate (due to the step-up in rate) and can award yourself a suitable salary. Liability also plays a role: with a limited liability company, you carry less liability personally for business debts. A customised evaluation is required in order to draw up a good comparison. We are happy to help you make an informed decision that suits your situation.
