Choosing the right legal structure is one of the first and most important decisions for anyone planning to establish a startup in Turkey. Entrepreneurs often focus primarily on the business idea, product development, software, marketing strategy, customer acquisition and investment opportunities. However, the legal structure selected at the beginning can significantly affect the startup’s taxation, founders’ personal liability, investment process, share transfers, corporate governance and even the possibility of a future exit.
A structure that appears inexpensive and simple during the first months of a startup may become problematic once the business begins to grow. Similarly, establishing a sophisticated corporate structure before the business model has been validated may create unnecessary administrative and financial burdens.
For this reason, there is no single answer to the question: Should a startup in Turkey be established as a sole proprietorship, limited liability company or joint stock company?
The correct choice depends on several factors, including the number of founders, expected turnover, investment plans, business risks, intellectual property ownership, employee stock options, future fundraising rounds and exit strategy.
This article explains the main legal differences between a sole proprietorship, a limited liability company and a joint stock company in Turkey and examines which structure may be more suitable for different types of startups.
Why Does the Legal Structure of a Startup Matter?
For many entrepreneurs, establishing a business is initially regarded as an administrative procedure required to issue invoices and receive payments. In reality, the legal structure of a startup goes far beyond taxation and accounting.
The structure selected by the founders determines, among other matters:
- whether the business has a separate legal personality,
- whether founders may become personally liable for business debts,
- how investors can acquire equity,
- how shares can be transferred,
- how corporate decisions are made,
- how new founders or investors can join the company,
- how profits can be distributed,
- whether employee equity arrangements can be structured efficiently,
- how intellectual property can be owned by the company,
- and how the startup may eventually be sold.
Therefore, the question should not simply be “Which type of company is cheaper to establish?”
A more appropriate question is:
“Which legal structure supports the startup’s business model, financing strategy and long-term objectives?”
This distinction is particularly important for technology startups, SaaS businesses, e-commerce companies, fintech projects, artificial intelligence companies and startups planning to obtain venture capital investment.
What Is a Sole Proprietorship in Turkey?
The expression “sole proprietorship” is frequently used in practice in Turkey to describe a commercial activity carried out directly by an individual entrepreneur.
It should be noted that a sole proprietorship is not equivalent to a limited liability company or joint stock company with a separate corporate personality. The individual entrepreneur and the business are not completely separated from each other in the same way that a shareholder is separated from a capital company.
This creates both advantages and disadvantages.
For an entrepreneur who wants to test an idea, provide consultancy services, develop software independently, work as a freelancer or operate a relatively low-risk business, starting operations as an individual may offer a practical solution.
However, when significant liabilities, employees, investors or business partners become involved, operating personally can create serious risks.
Advantages of a Sole Proprietorship for Startups
One of the main advantages of operating as an individual entrepreneur is simplicity.
The establishment process is generally easier than incorporating a capital company. Initial accounting and administrative costs may also be lower.
For this reason, a sole proprietorship can be particularly attractive for a founder who has not yet validated the business idea.
Imagine, for example, that an entrepreneur develops a small online service and currently has ten customers. The founder does not know whether the business will exist six months later.
In such circumstances, creating a complex shareholder structure may not always be necessary.
A sole proprietorship can allow the entrepreneur to:
- test the market,
- issue invoices,
- collect revenue,
- determine whether customers are willing to pay,
- and evaluate whether the business can become scalable.
For early-stage experimentation, this flexibility may be valuable.
Personal Liability Is the Main Risk of a Sole Proprietorship
The most significant disadvantage is personal liability.
Where the individual conducts the commercial activity directly, there is no corporate liability shield comparable to that provided by a limited liability company or joint stock company.
If significant business debts arise, creditors may potentially pursue the entrepreneur personally under the applicable rules.
This becomes particularly important when the startup begins signing contracts involving substantial financial obligations.
For example, a startup may enter into:
- office leases,
- software licensing agreements,
- cloud infrastructure contracts,
- employment agreements,
- supplier agreements,
- advertising contracts,
- bank financing arrangements,
- or customer contracts containing compensation obligations.
If the business operates personally, the entrepreneur’s business risk can become personal financial risk.
For this reason, a sole proprietorship may become less attractive once the scale and risk profile of the startup increase.
Taxation of a Sole Proprietorship
An entrepreneur operating individually is generally taxed under the rules applicable to individual commercial income rather than the corporate taxation applicable to capital companies.
One important consequence is that income taxation is progressive.
This means that the tax comparison between a sole proprietorship and a company should not be made simply by looking at the nominal tax rate.
Turnover, deductible expenses, profit margins, dividend plans, founder remuneration and other factors must also be considered.
For startups expecting rapid revenue growth, professional tax planning should therefore be carried out before selecting the legal structure.
Can a Sole Proprietorship Receive Startup Investment?
Technically, an investor may finance an entrepreneur through various contractual mechanisms. However, traditional equity investment becomes significantly more complicated because there are no corporate shares comparable to shares in a joint stock company.
An investor generally wants something identifiable in exchange for the investment.
For example:
“I invest EUR 500,000 and receive 15% of the company.”
This model requires a corporate capital structure.
Consequently, founders who intend to obtain angel investment or venture capital financing usually move toward a capital company structure.
For a startup that has already entered fundraising discussions, continuing to operate purely as a sole proprietorship may therefore create unnecessary restructuring work.
What Is a Limited Liability Company in Turkey?
A Turkish limited liability company, commonly referred to as a limited şirket or Ltd. Şti., is one of the most commonly used corporate structures in Turkey.
Under the Turkish Commercial Code, limited liability companies and joint stock companies are capital companies. A limited liability company has its own legal personality and its assets are legally separate from the personal assets of its shareholders.
A limited liability company may generally be incorporated by one or more individuals or legal entities and may have up to fifty shareholders. The Ministry of Trade currently states that the minimum capital requirement for a limited liability company is TRY 50,000. The capital may be paid within twenty-four months following registration in accordance with the applicable framework.
For many small and medium-sized businesses, this provides a practical balance between corporate protection and manageable governance requirements.
Why Do Many Entrepreneurs Choose a Limited Liability Company?
A limited liability company can be attractive because it provides a separate corporate structure without necessarily requiring the level of corporate sophistication associated with a joint stock company.
For example, consider two developers who create a software product together.
They expect approximately TRY 2 million in revenue during the first year but do not currently plan to seek external investment.
A limited liability company may offer several advantages.
The founders can define their ownership percentages, conduct commercial transactions through the company, employ personnel, acquire intellectual property and separate the company’s assets from their personal assets.
The company can also continue independently of changes in the founders’ personal circumstances.
For many traditional businesses and bootstrapped startups, these characteristics are sufficient.
Limited Liability Does Not Mean Zero Personal Risk
The term “limited liability company” sometimes creates the incorrect impression that shareholders can never become personally responsible for company obligations.
The issue is more complicated under Turkish law.
As a general corporate principle, company debts belong to the company and shareholders’ obligations toward the company are principally linked to their capital contributions.
However, public receivables require particular attention.
Under Article 35 of Law No. 6183 on the Procedure for the Collection of Public Receivables, shareholders of a limited liability company may be directly responsible, in proportion to their capital interests, for public receivables that cannot be fully or partially collected from the company or are determined to be uncollectible from the company. The legislation also contains specific rules concerning liability where shares are transferred.
This is an extremely important distinction for startup founders.
Taxes, social security liabilities and other public debts should therefore never be ignored merely because the business operates through a limited liability company.
Additionally, company managers may face separate liabilities arising from their managerial duties.
How Is a Limited Liability Company Managed?
A limited liability company operates primarily through two corporate structures:
- the general assembly of shareholders, and
- the manager or board of managers.
The general assembly makes decisions reserved to shareholders, while management and representation responsibilities are exercised by managers.
This governance structure is relatively straightforward for startups with a limited number of founders.
However, difficulties can arise if the company agreement is prepared using only generic incorporation language.
Suppose two founders each hold 50% of the company.
Founder A manages product development.
Founder B manages sales.
After two years, they disagree about whether to accept a new investor.
If important decisions require shareholder approval and neither founder can obtain a majority, the company may experience a serious deadlock.
For this reason, startup founders should not rely exclusively on the standard company agreement.
A separate shareholders’ agreement or founders’ agreement should usually regulate issues such as:
- management powers,
- reserved matters,
- voting thresholds,
- founder departure,
- vesting,
- intellectual property,
- confidentiality,
- non-compete obligations where legally permissible,
- share transfers,
- deadlock mechanisms,
- tag-along rights,
- drag-along rights,
- investment rounds,
- and exit procedures.
Is Share Transfer Easy in a Limited Liability Company?
This is one of the areas where the difference between limited liability companies and joint stock companies becomes especially important.
Transfers of shares in Turkish limited liability companies involve specific legal formalities.
According to the Ministry of Trade’s investment guidance, a limited liability company share transfer generally requires a written share transfer agreement with notarised signatures, approval of the general assembly unless otherwise provided, and registration and announcement procedures.
This structure may be perfectly acceptable for a company whose shareholders rarely change.
However, startups may experience frequent equity transactions.
For example:
A startup begins with three founders.
Six months later, an angel investor joins.
One year later, a seed investment fund invests.
Eighteen months later, another fund participates in a Series A financing round.
An early founder sells part of his or her interest.
A new strategic investor enters.
In such circumstances, frequent share transfers and corporate restructuring may make the joint stock company structure more practical.
Is a Limited Liability Company Suitable for Venture Capital Investment?
It can be.
There is no rule stating that a startup cannot receive investment because it is a limited liability company.
However, the more complex the investment structure becomes, the more likely investors are to prefer a joint stock company.
Institutional investors often examine questions such as:
- Can shares be transferred efficiently?
- Can different investment rights be structured?
- Can investors obtain board representation?
- Can preferential economic rights be implemented?
- How will future investment rounds work?
- Can founders and investors execute drag-along and tag-along arrangements?
- What happens during an exit?
- How easily can ownership change?
Consequently, a limited liability company may be suitable for an early-stage or bootstrapped startup but may eventually need to be converted into a joint stock company as the fundraising strategy develops.
What Is a Joint Stock Company in Turkey?
A Turkish joint stock company, known as an anonim şirket or A.Ş., is another capital company regulated under the Turkish Commercial Code.
A joint stock company has a separate legal personality. Its capital is divided into shares and, as a general rule, the company itself is responsible for its debts with its own assets.
According to the Ministry of Trade, the minimum share capital for newly established joint stock companies is currently TRY 250,000. At least one quarter of cash capital must generally be paid before registration, with the remaining amount payable within twenty-four months. For non-public joint stock companies using the registered capital system, the minimum initial capital is TRY 500,000.
These capital requirements should be considered together with the startup’s financing plans.
Why Are Joint Stock Companies Popular Among Investment-Oriented Startups?
The main advantage is not simply prestige.
The joint stock company structure is better suited to businesses in which ownership may change regularly.
A technology startup seeking angel investors, venture capital funds and eventually an acquisition or public offering usually needs a flexible equity structure.
A joint stock company provides a more investment-oriented legal framework.
The shares may generally be transferred more efficiently than limited liability company interests. The Ministry of Trade notes that, subject to applicable exceptions, transfers of joint stock company shares are generally not subject to registration and announcement, whereas limited liability company share transfers are subject to more formal procedures.
This distinction can become highly significant during financing rounds.
Joint Stock Company and Investor Entry
Suppose a startup has an initial valuation of EUR 1 million.
An investor contributes EUR 250,000.
The founders and investor agree that the investor will receive a defined percentage of the company.
Later, a second financing round occurs at a EUR 4 million valuation.
New shares may be issued and the existing shareholders’ percentages may become diluted.
When corporate structure, investment agreements and shareholder rights are correctly planned, this process can be managed systematically.
This is one reason many startups expecting multiple investment rounds prefer the A.Ş. structure from the beginning.
Joint Stock Companies and Startup Exits
The possibility of an exit is central to venture capital.
Investors usually do not invest solely to receive annual dividends.
They expect their shares eventually to be sold at a higher value.
An exit may occur through:
- sale of the startup to another company,
- sale of investor shares to another investor,
- acquisition by an international technology company,
- merger,
- strategic acquisition,
- secondary share sale,
- or, for sufficiently developed businesses, a public offering.
Accordingly, share transfer flexibility becomes an important legal issue.
If the founders believe that the startup may eventually be sold, the corporate form should be chosen with the exit process in mind from the beginning.
Sole Proprietorship vs Limited Liability Company vs Joint Stock Company
The practical differences can be summarised as follows.
Sole Proprietorship
A sole proprietorship may be suitable where:
- there is one founder,
- the business is still being tested,
- turnover remains limited,
- commercial risk is relatively low,
- there are no outside investors,
- and the founder wants a relatively simple initial structure.
However, personal liability and the absence of a corporate share structure make it less suitable for scalable startups.
Limited Liability Company
A limited liability company may be appropriate where:
- there are one or several founders,
- a separate legal entity is required,
- external investment is not expected immediately,
- the business is expected to remain closely held,
- shareholders are unlikely to change frequently,
- and the founders want a capital company with relatively straightforward governance.
For many SMEs and bootstrapped businesses, an Ltd. Şti. may be entirely sufficient.
Joint Stock Company
A joint stock company may be preferable where:
- venture capital investment is expected,
- several financing rounds are planned,
- investors may enter and exit,
- share transfers are important,
- sophisticated shareholder rights will be required,
- international investors are being approached,
- employee equity arrangements are contemplated,
- or a future acquisition or exit is part of the business plan.
For a genuinely scalable startup, the A.Ş. structure often offers important strategic advantages.
Which Structure Is Better for a Technology Startup?
A technology startup should generally consider not only its current size but also its expected development.
Suppose three university students develop an artificial intelligence application.
At the moment, the company has no customers and no revenue.
If the founders simply want to test the product, operating initially through a simple structure may seem reasonable.
However, imagine that they already plan to participate in accelerator programmes and raise EUR 1 million within the next twelve months.
In this case, incorporation as a joint stock company from the beginning may avoid restructuring costs later.
By contrast, if a software developer provides services to five corporate customers and intends to finance the business entirely from operating revenue, a limited liability company may provide sufficient corporate protection without creating a more complex structure than necessary.
Therefore, the correct legal form depends on the startup’s future financing model, not merely its present turnover.
Intellectual Property Must Be Considered During Incorporation
Another commonly overlooked issue is intellectual property.
A startup may have valuable assets even before it has significant revenue.
These assets may include:
- source code,
- algorithms,
- trademarks,
- domain names,
- mobile applications,
- software architecture,
- databases,
- designs,
- patents,
- trade secrets,
- customer lists,
- and proprietary business processes.
Investors will generally want these assets to belong to the company rather than personally to one of the founders.
Consider a startup where Founder A owns 40%, Founder B owns 30% and an investor owns 30%.
If the software source code remains legally owned by Founder A personally, the investor may face a major risk.
What happens if Founder A leaves?
Can the company continue using the software?
Was intellectual property properly assigned?
For this reason, incorporation and intellectual property transfers should be coordinated from the outset.
Founders’ Agreements Are as Important as the Company Type
Choosing between an Ltd. Şti. and an A.Ş. does not by itself prevent founder disputes.
One of the most common startup mistakes is to establish a company with friends without clearly defining their legal relationship.
For example, three founders may each receive one-third of the company.
After six months, one founder stops working.
The remaining founders continue developing the product for three years.
The inactive founder still owns one-third of the company.
This situation can become extremely difficult when investors arrive.
A properly structured founders’ agreement can address such risks through mechanisms including vesting, good leaver and bad leaver arrangements, transfer restrictions and buy-back or contractual exit mechanisms, subject to their compatibility with mandatory Turkish law.
What Is Vesting and Why Is It Important?
Vesting means that a founder’s economic participation in a startup is linked to continued involvement over a defined period.
For example, founders may agree on a four-year vesting schedule.
If a founder leaves after a short period, that founder may not retain the full economic benefit originally contemplated.
The purpose is to prevent a situation in which someone who contributed for three months retains the same long-term economic participation as founders who work for the startup for five years.
Vesting arrangements require careful drafting under Turkish law because international startup templates cannot always be copied directly into Turkish corporate structures.
The legal form chosen for the startup may therefore affect how such mechanisms are implemented.
What About Employee Stock Options?
High-growth startups frequently compete for talent by offering employees participation in future company value.
Instead of paying an exceptionally high salary, the startup may offer an employee:
salary + bonus + equity-related incentive.
This is common internationally, particularly among technology companies.
However, employee stock option structures require careful corporate, tax and employment law analysis in Turkey.
A joint stock company will often provide greater flexibility for sophisticated equity arrangements than a sole proprietorship.
For this reason, startups planning to create an ESOP or similar employee incentive programme should consider this issue before deciding on their corporate structure.
Can a Startup Change Its Company Type Later?
Yes, restructuring may be possible under Turkish commercial law.
A business may begin with one structure and later move toward another corporate model where legal requirements are satisfied.
However, restructuring is not costless.
The process may involve:
- corporate resolutions,
- amendments to constitutional documents,
- accounting procedures,
- registration formalities,
- tax analysis,
- contract reviews,
- bank documentation,
- licence updates,
- intellectual property records,
- investor approvals,
- and regulatory considerations.
Therefore, founders expecting rapid growth should consider whether selecting a scalable corporate structure from the beginning would be more efficient.
Minimum Capital Should Not Be the Only Factor
As of 2026, the official minimum capital thresholds are TRY 50,000 for limited liability companies and TRY 250,000 for ordinary joint stock companies, while a higher initial threshold applies to non-public joint stock companies adopting the registered capital system.
However, founders should not select a company type simply because one requires less minimum capital.
A startup planning to raise millions of euros should not choose a structure solely to save initial incorporation costs.
Likewise, a founder testing a modest business should not necessarily establish an unnecessarily sophisticated structure simply because it appears more prestigious.
Legal structure should follow business strategy.
Corporate Tax Considerations
Taxation is another important factor.
Capital companies such as limited liability companies and joint stock companies are subject to corporate taxation. According to the Turkish Revenue Administration, the general corporate income tax rate applicable to ordinary corporate taxpayers for the 2026 accounting period is 25%, although different rates apply to certain categories of entities.
However, taxation should never be analysed only by comparing the corporate tax rate with individual income tax rates.
Dividend distributions, salaries paid to founders, deductible expenses, withholding obligations, VAT, social security costs and international tax considerations may materially affect the outcome.
Startups with foreign founders or international investors should additionally analyse issues such as:
- double taxation treaties,
- withholding tax,
- permanent establishment risks,
- transfer pricing,
- cross-border service arrangements,
- intellectual property licensing,
- and payments to foreign shareholders.
What Should Foreign Founders Consider?
Foreign individuals and foreign companies may generally participate in Turkish companies subject to the applicable investment, commercial and sector-specific regulations.
For an international startup, the corporate structure becomes especially important because investors may require:
- clearly documented share ownership,
- bilingual corporate documents,
- intellectual property assignments,
- investment agreements,
- shareholder agreements,
- board representation rights,
- information rights,
- liquidation preferences,
- anti-dilution mechanisms,
- and clearly defined exit rights.
These requirements are much easier to address when the corporate structure has been planned before investment negotiations begin.
Common Mistakes When Establishing a Startup in Turkey
One of the biggest mistakes is choosing a company type based exclusively on accountant fees.
Another is copying a standard company agreement without adapting it to the founders’ relationship.
Other frequent mistakes include:
- failing to execute a founders’ agreement,
- failing to transfer intellectual property to the company,
- giving equal shares automatically without considering contribution levels,
- failing to establish vesting mechanisms,
- ignoring what happens if a founder leaves,
- accepting an investor without analysing dilution,
- granting excessive management rights to a minority investor,
- failing to regulate future financing rounds,
- failing to address deadlock situations,
- and ignoring exit arrangements.
These problems may appear unimportant when the company is worth TRY 100,000.
They can become extremely serious when the startup is worth EUR 10 million.
Which Company Type Should a Startup Choose?
There is no universal answer.
For a single founder who is testing a business concept with minimal financial exposure, a sole proprietorship may provide an efficient starting point.
For founders building a stable business that is expected to remain closely held, a limited liability company may provide an appropriate balance between legal personality, operational simplicity and corporate protection.
For startups planning to raise venture capital, issue equity to investors, conduct multiple financing rounds, implement employee equity programmes or pursue a future exit, a joint stock company will often deserve serious consideration.
A useful rule of thumb is:
The more important external investment, share transfers and future exit possibilities are to the business model, the stronger the reasons for considering a joint stock company structure.
The more closely held and operationally straightforward the business is expected to remain, the more attractive a limited liability company may be.
A sole proprietorship, on the other hand, is generally most appropriate where the entrepreneur is still testing the commercial viability of the business and the legal and financial risks remain limited.
Conclusion
Choosing between a sole proprietorship, limited liability company and joint stock company for a startup in Turkey is not merely an incorporation decision. It is a strategic legal decision that can influence almost every stage of the startup lifecycle.
A structure suitable for a freelance entrepreneur may not be appropriate for a technology company seeking venture capital.
A limited liability company that operates efficiently with two founders may become inconvenient when five different investors need to enter the shareholding structure.
Likewise, establishing a joint stock company may be unnecessary for a business that has no intention of raising external investment or changing shareholders.
Before establishing a startup in Turkey, founders should therefore evaluate not only their current business but also their expected position over the next three to five years.
The analysis should include the number of founders, allocation of shares, founder responsibilities, intellectual property ownership, personal liability, tax exposure, investment strategy, employee equity plans, share transfers, corporate governance and exit expectations.
Most importantly, incorporation documents should not be treated as routine paperwork.
For a scalable startup, the company’s articles of association, founders’ agreement, shareholders’ agreement, intellectual property assignments and investment documentation collectively form the legal architecture of the business.
Establishing that architecture correctly at the beginning can prevent founder disputes, facilitate investment negotiations and significantly reduce legal risks during future financing or acquisition processes.
For this reason, entrepreneurs planning to establish a startup in Turkey should obtain legal and tax advice tailored to their particular business model before deciding whether to operate as a sole proprietorship, limited liability company or joint stock company.
