MERSIS is the front door to Turkish company registration, but it is not the whole job. You still need the right company type, the right capital figure, and a file that will hold up at the Trade Registry Directorate. The official Invest in Türkiye guide says company establishment runs through Trade Registry Directorates designed as a one-stop shop, while MERSIS is the online system used for the memorandum and articles of association. That sounds simple. In practice, the file only moves cleanly when the structure is already settled.
That is why foreign founders should treat MERSIS as a workflow, not as a form-filling exercise. Before the first online entry, you should already know whether you are opening an LLC or a JSC, whether the capital amount is realistic, and who will appear in the file as shareholder, manager, and address contact. Corpenza's company formation and accounting team, the broader Turkey company formation guide, and the separate note on forming an anonim şirket help with those earlier decisions.
What is MERSIS, and what does it actually handle?
MERSIS is the official electronic registry layer for Turkish trade-registration work. The Invest in Türkiye guide says the memorandum and articles of association are submitted online to MERSIS, and it describes MERSIS as the Central Registry Record System used to carry out commercial registry processes and store registry data electronically. The portal itself tells users to carry out trade-registry transactions online through MERSIS.
So MERSIS is not a side tool. It is the place where the company record starts taking shape. The live portal also says the system has been used across 238 trade registry directorates, which matters for founders who assume every city or chamber follows a different digital logic. The front end is centralized. The quality of your file is what changes.
What should be decided before you open the file?
The file should open only after the legal structure and capital plan are already clear. According to the Ministry of Trade notice that took effect on 1 January 2024, a new limited company requires at least TRY 50,000 in capital, a new anonymous company requires at least TRY 250,000, and a non-public joint stock company using the registered-capital system starts at no less than TRY 500,000. Those are not drafting details. They shape the MERSIS entry from the first screen.
This is where many foreign founders waste time. They start the digital file first, then revisit the company type later. That usually means the articles, the capital line, or the governance logic has to be corrected after the draft already exists. A calmer sequence works better: choose the company form, align the capital figure, confirm shareholder details, then enter MERSIS.
What does the official registration path look like?
The official path has two layers. First, the constitutional documents are entered online through MERSIS. Then the file moves to the Trade Registry Directorate that will handle the incorporation. The same Invest in Türkiye page says company establishment is carried out at Trade Registry Directorates located in Chambers of Commerce and designed as a one-stop shop, and that the process is completed within the same day once the file is ready.
The Ministry's Trade Registry page adds useful context. It defines the trade registry as the state register that holds the information and records on traders and commercial enterprises, and says those records are kept by trade registry directorates within chambers of commerce and industry or commerce chambers under ministry supervision. In other words, MERSIS does not replace the registry directorate. It prepares the file for it.
How long does MERSIS registration really take?
The official same-day promise is real, but it applies to the registry process once the file is ready. It should not be read as a promise that every foreign-founder setup starts from zero in the morning and ends with a finished company by evening. The time savings show up after the file is clean, the capital line fits the chosen company type, and the constitutional documents stop changing.
That distinction matters. Founders often blame MERSIS for delays that started earlier: a shareholder passport detail was entered differently across documents, the address plan was not final, or the capital logic changed after the draft articles were written. The system moves faster than a messy file. That is the pattern to keep in mind.
Where do foreign founders usually get stuck?
Most problems come from preparation, not from the portal itself. The common ones are a company type chosen without looking at the current capital floor, inconsistent shareholder details, and draft articles that do not match the intended governance structure. The official sources are clear on the framework. What slows the project is usually the gap between that framework and the actual file entered into MERSIS.
There is another practical issue. Some founders treat MERSIS as if it were the entire Turkish incorporation process. It is not. It is the digital registry backbone. You still need a coherent company form, a workable capital plan, and a file that the registry directorate can process without another round of fixes. If you want a broader setup map, Corpenza's tax structuring support and advisory team are the natural next step.
FAQ
Can a foreign founder use MERSIS for a Turkish company?
Yes. The Invest in Türkiye guide says international investors have the same rights and liabilities as local investors and may establish any company form set out in the Turkish Commercial Code.
Does MERSIS mean I no longer deal with the Trade Registry Directorate?
No. MERSIS handles the electronic registry workflow, but the incorporation still runs through the relevant Trade Registry Directorate.
Is same-day registration guaranteed?
No. The official wording is that the process is completed within the same day once the file is ready. Preparation can still take longer if the structure or documents keep changing.
What capital figure should I check before starting?
For 2026, the live ministry notice says TRY 50,000 for a new limited company and TRY 250,000 for a new anonymous company, with TRY 500,000 as the starting floor for a non-public JSC using the registered-capital system.
