D’Autònom a SL: When is the Idoni Time for the Jump?
Most entrepreneurs and independent professionals begin their business adventure by registering with the self-employed regime. It is a fast, economical formula with few formal requirements. However, as the business grows, so do revenues, corporate risks, and business needs. At this point, an inevitable question arises: when is it time to move from self-employed to SL?
Taking this leap is not only a matter of prestige or brand image; It is a strategic decision that directly affects your taxes, your legal liability and the financial structure of your project. In this article, we look at the key indicators that determine the right time to make the switch safely.
1. The financial and fiscal criterion: The volume of net profits
The most common reason for considering the change from self-employed to SL is tax optimisation. The key lies in the difference in operation between Personal Income Tax and Corporate Income Tax:
- The self-employed person is taxed by personal income tax: This is a progressive tax. The more you earn, the higher the percentage you pay, which can exceed 45% in the highest brackets depending on the autonomous community.
- The Limited Company is taxed by Corporation Tax: It is a tax with a fixed tax rate, generally 25% (and a reduced rate of 15% for newly created companies during the first year with profits and the following one).
The general rule: Financially, the jump begins to be profitable when the net profit of the activity (income minus deductible expenses) exceeds the barrier of €40,000 to €50,000 per year, and provided that a part of that money stays within the company for reinvestment or reserves instead of being used entirely for personal consumption.
2. The legal criterion: Protection of personal assets
Beyond taxes, there’s a critical legal risk factor that many entrepreneurs overlook:
As a self-employed person or individual, your liability to third parties is unlimited. This means that you are responsible for your business’s debts with all your present and future assets (such as your bank account, car or own home).
By setting up a Limited Company (S.L.), the company acquires its own independent legal personality. Liability is strictly limited to the capital contributed to the company. Your personal assets are protected against possible claims from suppliers, creditors or financial problems of the activity, except in cases of gross negligence or administrator crime.
3. Relationship of pros and cons of the business structure
| Structure as a Self-Employed | Structure as a Limited Company (S.L.) | |
| Legal | Unlimited (affects personal assets). | Limited to the capital contributed by the company. |
| Tax type | Progressive (personal income tax up to more than 45%). | Fixed (Corporation Tax 15% or 25%). |
| Incorporation | Practically free and immediate. | It requires share capital, notary and registration. |
| Accounting | Simple (basic record books). | Complex (mandatory commercial accounting). |
4. The need for partners, financing and commercial image
There are other key indicators that are not directly monetary that make the move from self-employed to SL advisable:
- Entry of new partners or investors: A company allows the capital to be divided into shares in a clean and regulated way for future partners or external investors.
- Access to bank financing: Financial institutions tend to offer better lines of credit and financing conditions to structured companies with annual accounts deposited in the Mercantile Registry than to an individual self-employed person.
- Tenders and large customers: Many multinationals and public bodies require that they be incorporated as a commercial company as a requirement for approving suppliers, as it conveys greater stability and commercial solidity.
Important legal note: Currently, the current regulations on the creation of companies already allow the incorporation of an S.L. with a capital of less than the classic €3,000 (even from €1) under the successive formation regime, eliminating a great barrier to economic entry.

How to plan for change from a professional setting
The process of transforming the self-employed into an S.L. requires accounting planning and the advice of a professional team to avoid duplicates in invoicing or problems in the transfer of goods and contracts during the transition period.
