📌 What Will You Find in This Guide?
When starting a new business, the first question asked is usually not "what product will I sell" or "which market will I enter," but "which company type should I start with." The difference between a sole proprietorship, a limited company, and a joint stock company is not merely a change of name on paper; it directly determines your formation cost, tax burden, personal liability, and whether your company will be able to raise investment down the line.

1. What Are a Sole Proprietorship, Limited Company, and Joint Stock Company?
Under Turkish law, commercial activity is carried out through three main structures. A sole proprietorship is a business set up in the name of a single individual under the Turkish Commercial Code (TCC) and the Income Tax Law; it has no legal personality and is legally merged with the business owner. A limited company and a joint stock company, on the other hand, are structures regulated under the capital companies heading of the TCC, each with its own legal personality.
Sole Proprietorship
Set up by a single individual, with no legal personality. The business owner and the business are legally the same person; debts and receivables belong directly to the individual.
Limited Company
A capital company that can be set up with 1-50 partners. The partners' liability is limited to the capital share they have committed.
Joint Stock Company
A capital company whose capital is divided into shares, which can be set up with at least 1 partner and has no legal cap on the number of partners.
In practice, the most commonly set up type of capital company is the limited company; ventures with plans to grow, raise investment, or go public generally either prefer the joint stock company structure or transition to it over time.
2. Comparison of Formation Cost and Time
Formation cost is usually the first deciding criterion for entrepreneurs. As of 2026, the cost difference between the three company types is fairly noticeable.
| Criterion | Sole Proprietorship | Limited Company | Joint Stock Company |
|---|---|---|---|
| Formation Cost | ~TL 8,000 - 13,500 | ~TL 24,000 - 32,000 | ~TL 33,000 - 42,000 |
| Capital Blockage | None | None | 1/4 of capital blocked at the bank |
| Formation Time | 1-3 business days | 3-7 business days | 5-10 business days |
| Bookkeeping/Filing Burden | Relatively low | Medium - high | High |
Figures are average amounts that vary by province, chamber of commerce, and the accounting firm you choose; contact us for the exact cost.
What Does Capital Blockage Mean in a Joint Stock Company?
When setting up a joint stock company, at least a quarter of the committed cash capital must be deposited and blocked at a bank before registration. There is no such upfront payment requirement in a limited company; the capital commitment can generally be transferred to the company within 24 months of formation.
3. The Liability Difference: Why Is It a Critical Decision Criterion?
The issue most often overlooked when choosing a company type — yet carrying the highest risk — is the liability regime. As your business grows, or as you operate in a sector with increasing debt exposure, this difference becomes progressively more important.
Sole Proprietorship: Unlimited Liability
In a sole proprietorship, the business and the business owner are legally the same person. All of the entrepreneur's personal assets (including their home, car, and bank accounts) fall within the scope of liability for the business's debts. If the business risk is low, this is manageable; but in businesses with high supplier, credit, or contract risk, it can turn into a significant disadvantage.
Limited/Joint Stock: Limited Liability
In a limited company and a joint stock company, the partners' liability is, in principle, limited to the capital share they have committed to the company. As a general rule, a partner's personal assets cannot be pursued for the company's commercial debts. (Exception: partners of a limited company can still be held liable, in proportion to their capital share, for public debts — such as tax or social security premiums — that cannot be collected from the company.)
4. Tax Differences: Income Tax or Corporate Tax?
Tax burden differs significantly between company types depending on your profit margin and growth speed. The core rates in force as of 2026 are as follows:
Sole Proprietorship: Progressive Income Tax
A sole proprietorship's profit is taxed, as the business owner's commercial income, under the Income Tax Law on a bracketed tariff ranging from 15% to 40%. For 2026, the first bracket threshold for non-wage (commercial) income is TL 190,000, and the top bracket threshold is TL 5,300,000. Tax is collected in a single stage; there is also no dividend withholding.
For young entrepreneurs between the ages of 18-29 who establish tax liability for the first time, TL 400,000 of earnings is exempt from income tax for 3 taxation periods in 2026. This exemption covers only income tax; it does not affect VAT or other obligations.
Limited/Joint Stock: Two-Stage Taxation
In limited and joint stock companies, profit is first subject to a 25% corporate tax at the company level (30% for banking and financial institutions, or 20% with a 5-point reduction on export earnings). When the profit is distributed to partners, a second-stage dividend withholding — raised from 10% to 15% under the Presidential Decision dated December 22, 2024 — then comes into play.
For companies that keep their profit within the company and redirect it into new investment rather than distributing it, this second stage does not come into play; this is why the flat 25% rate can be advantageous compared to the bracketed income tax tariff at high profit levels for growth-focused ventures.
Is There a Difference in Terms of VAT?
VAT liability is independent of company type; all three structures are subject to VAT at the general rate of 20% (1% or 10% on some goods and services). Company type does not determine the VAT rate, only which tax regime the earnings will be subject to.
| Tax Item | Sole Proprietorship | Limited / Joint Stock |
|---|---|---|
| On Earnings | Income Tax (15% - 40%) | Corporate Tax (25%) |
| Profit Distribution | No additional withholding | 15% dividend withholding |
| VAT | 20% (general rate) | 20% (general rate) |
5. Minimum Capital Requirements (2026 Current)
There is no legal minimum capital requirement for a sole proprietorship. For capital companies, the amounts set by the TCC and the Presidential Decision apply.
Sole Proprietorship
No Minimum Capital
Limited Company
TL 50,000
Joint Stock Company
TL 250,000
For non-public joint stock companies that have adopted the registered capital system, the starting capital is TL 500,000.
⚠️ The December 31, 2026 Compliance Deadline
These amounts already apply to companies established after January 1, 2024. Existing limited and joint stock companies established before that date whose capital falls below these amounts must raise their capital to the legal minimum by December 31, 2026; otherwise, the company is deemed dissolved by law. While this issue is clear for new company formations, entrepreneurs who will take over an existing company or work with a company established before that date must keep this deadline firmly on their agenda.
6. Number of Partners, Management Structure, and Share Transfer
| Criterion | Sole Proprietorship | Limited Company | Joint Stock Company |
|---|---|---|---|
| Number of Partners | A single individual | 1 - 50 partners | 1 - unlimited partners |
| Management | Business owner | Manager(s) | Board of directors |
| Share Transfer | Cannot be transferred, business closes | Requires notarization + registration + announcement | Via share ledger entry, generally simpler |
In a limited company, a partner transferring their share requires a notarized transfer agreement, general assembly approval, registration, and announcement steps; this means cost and time. In a joint stock company — especially if bearer share certificates have been issued — a share transfer can take place much faster and at a lower cost. This difference is an important distinguishing point for ventures planning to take on investors or transfer shares frequently.
7. Corporate Reputation and Growth Potential
The choice of company type affects not just today's cost but also the company's future growth trajectory. Corporate customers, banks, and investors approach different company types with a different level of trust.
Sole Proprietorship
Provides a fast start with low bureaucracy; but may sometimes inspire less confidence than a capital company in corporate customer and tender processes. Raising outside investment is almost impossible.
Limited Company
Strikes a balance between corporate visibility and reasonable cost. Suitable for angel investors and structures with a small number of partners; not ideal for large rounds with many investors.
Joint Stock Company
The most suitable structure for institutional investors, venture capital funds, and IPO processes. The relative ease of share transfer also allows for share-based incentive (option) plans.

9. Is It Possible to Change Company Type Later?
Most entrepreneurs prefer to start with a low-cost structure in the first years and switch to a capital company as their business grows. This transition is possible under Turkish law and is referred to as a "type conversion."
Converting From a Sole Proprietorship to a Capital Company
Under the Trade Registry Regulation and Articles 182-193 of the TCC, individual commercial enterprises can change type and convert into a limited or joint stock company. In this process, a type conversion plan is prepared, an application is made through MERSIS, the new articles of association are registered and announced, and the necessary notifications are made to social security, the tax office, and the Revenue Administration.
Converting From a Limited Company to a Joint Stock Company
A limited company can also be converted into a joint stock company under the same type conversion provisions. This is generally the step chosen when a company is preparing to take on investors, its number of partners increases, or an IPO plan comes onto the agenda.
When Is It Necessary?
- When revenue and profit start entering the higher bracket of the income tax tariff
- When corporate customer/tender conditions require a capital company
- When an angel investor, venture capital fund, or corporate partner will be brought on
- When limiting liability to capital becomes a priority
- When an IPO or institutionalization plan becomes concrete (generally a conversion to joint stock)

10. Frequently Asked Questions
1. Which company type makes more sense for a first-time entrepreneur?
For a one-person, low-risk business with limited capital needs, a sole proprietorship offers a fast, low-cost start. If there are multiple partners, a need for limited liability, or an expectation of corporate customers, a limited company is generally a more balanced choice.
2. Are limited company partners not liable for any debt at all?
Liability for commercial debts is, in principle, limited to the capital share. However, for tax and social security premium debts that cannot be collected from the company, legal representatives and partners can be held liable, under certain conditions, in proportion to their capital shares.
3. Why is TL 250,000 in capital required to set up a joint stock company?
This amount is the minimum capital requirement set under the TCC framework by the Presidential Decision, effective from January 1, 2024. It is not necessary for the entire capital to be held in cash and ready; however, at least a quarter must be deposited and blocked at a bank before registration.
4. When does it make sense to convert my sole proprietorship into a limited company?
We recommend considering a type conversion when your earnings approach the higher brackets of the income tax tariff, when corporate customer/tender processes require a capital company, or when limiting your liability becomes a priority.
5. Which type should I set up if I'm planning to take on investors?
For ventures planning to work with institutional investors, an angel investor network, or venture capital funds, a joint stock company structure is generally more suitable because share transfer is relatively easier. Starting with a limited company in the early stage and converting to a joint stock company before investment is also a commonly used path.
6. In which company types does dividend withholding apply?
Dividend withholding applies only in capital companies subject to corporate tax, such as limited and joint stock companies, when profit is distributed to partners. As of 2026, this rate is 15%. There is no separate dividend distribution withholding in a sole proprietorship.
7. In which company type does the young entrepreneur exemption apply?
The young entrepreneur earnings exemption applies to sole proprietorships that establish income tax liability under the real regime; partnership in a limited or joint stock company does not fall within the scope of this exemption.
11. Conclusion: How Should the Right Equation Be Solved?
There is no single "best" option among a sole proprietorship, a limited company, and a joint stock company; there is a right option. This choice is shaped by the scale of your business model, your risk tolerance, your profit expectations, and your investment/growth plans.
Low-risk, one-person businesses requiring a fast start fit well with a sole proprietorship; medium-scale ventures wanting limited liability fit well with a limited company; and companies aiming to attract investors and grow at scale fit well with a joint stock company.
Making this decision requires evaluating formation cost, tax burden, the liability regime, and your future growth plan together. From determining the company type suited to your needs, through the formation process, to your post-formation accounting and reporting obligations, we are by your side throughout the entire process.
