Sole Proprietorship or Simple LLC (j.d.o.o.) in 2026 – How to Choose the Best Legal Business Structure?

by Cowork Zagreb.

Starting your own business is one of the most important professional steps, and one of the first decisions is choosing a legal business structure. Many entrepreneurs, freelancers, and startup founders ask the same question: sole proprietorship or simple LLC (j.d.o.o.) – which is more worthwhile in 2026?

The choice between a sole proprietorship and a simple limited liability company affects not only administration and taxes, but also personal liability, business growth opportunities, collaboration with clients, and the overall costs of doing business.

In this guide, we provide a detailed comparison of a sole proprietorship and a simple LLC (j.d.o.o.), an overview of costs, tax obligations, and practical advice for entrepreneurs who want to make the best decision.

Sole Proprietorship or Simple LLC (j.d.o.o.) – The Basic Differences

Although both forms allow the legal conduct of business activities, there are significant differences.

Characteristic	Sole Proprietorship	Simple LLC (j.d.o.o.)
Owner	Natural person	One or more founders
Liability	Personal assets are liable for obligations	Liability is limited to the company’s assets
Formation	Simple and fast	More complex procedure
Bookkeeping	Flat-rate taxation or business records	Double-entry bookkeeping
Operating costs	Lower	Higher
Investors and partners	Less attractive	Greater business credibility
Growth potential	More limited	More suitable for business expansion

The most important difference relates to liability. A sole proprietor is personally liable for debts with their private assets, while the owner of a simple LLC (j.d.o.o.) is generally liable only with the company’s assets.

Why Is Choosing a Legal Business Structure Important Right from the Start?

Many entrepreneurs consider the choice between a sole proprietorship and a simple LLC (j.d.o.o.) to be a formality that can be dealt with along the way, but this decision has a long-term impact on tax obligations, administrative processes, financing opportunities, and the protection of personal assets. Changing the legal business structure later is possible, but it often requires additional costs and administrative procedures. For this reason, it is recommended to analyze your business model, expected revenue, and growth plans before registering your business.

When Is a Sole Proprietorship the Best Choice?

A sole proprietorship is often the ideal solution for:

• freelancers
• IT professionals
• marketing consultants
• designers
• photographers
• tradespeople and craftsmen
• individuals who are just testing a business idea

The advantage of a sole proprietorship lies in its simplicity. Administrative requirements are lower, and operating costs are significantly lower than those of companies.

A flat-rate sole proprietorship is particularly popular, as it allows for simple taxation and minimal administrative work.

Advantages of a Sole Proprietorship

• Fast formation
• Low startup costs
• Simpler business operations
• Lower accounting costs
• Flexibility for self-employed entrepreneurs

Disadvantages of a Sole Proprietorship

• Personal liability for debts
• Limited opportunities to attract investors
• Some larger clients prefer working with companies

When Should You Choose a Simple LLC (j.d.o.o.)?

A simple LLC (j.d.o.o.) is often a better choice for entrepreneurs who plan more serious business growth, hiring employees, or working with larger clients.

Many companies and corporations perceive a simple LLC (j.d.o.o.) as a more professional business structure, which can help when securing larger contracts.

Advantages of a Simple LLC (j.d.o.o.)

• Limited personal liability
• Greater business credibility
• Easier inclusion of partners and investors
• Clear separation of personal and business finances

Disadvantages of a Simple LLC (j.d.o.o.)

• Higher bookkeeping costs
• More complex accounting
• More administrative obligations
• Slower formation process

Tax Obligations of Sole Proprietorships and Simple LLCs (j.d.o.o.) in 2026

The tax aspect is often the deciding factor when choosing a legal business structure.

Taxes for Sole Proprietorships

Sole proprietors can operate:

• as flat-rate sole proprietors
• as sole proprietors who keep business records

With a flat-rate sole proprietorship, tax obligations are simpler and more predictable, making it an attractive option for freelancers and small entrepreneurs.

Taxes for Simple LLCs (j.d.o.o.)

A simple LLC (j.d.o.o.) pays corporate income tax and is required to maintain double-entry bookkeeping. An owner who wishes to distribute profits must also comply with the tax rules relating to profit distribution.

As a result, the overall tax burden may be more complex than that of a sole proprietorship, while at the same time providing greater flexibility for business development.

How to Assess Which Option Is More Financially Beneficial?

When comparing a sole proprietorship and a simple LLC (j.d.o.o.), it is not enough to consider only the tax rates. It is important to take into account the overall costs of doing business, including bookkeeping, social contributions, banking fees, business premises, and administrative obligations. Entrepreneurs with lower revenues often prefer a sole proprietorship because of its simpler operations, while those planning significant revenue growth or hiring employees more frequently choose a simple LLC (j.d.o.o.) because of its better legal protection and professional image.

How Much Does It Cost to Start a Sole Proprietorship in 2026?

The costs of establishing a sole proprietorship are relatively low.

The most common costs include:

• sole proprietorship registration
• company stamp production (if required)
• opening a business bank account
• any required permits or licenses
• bookkeeping services

For most business activities, it is possible to start operating with minimal initial investment.

How Much Does It Cost to Start a Simple LLC (j.d.o.o.)?

With a simple LLC (j.d.o.o.), you should expect the following costs:

• share capital
• notary fees
• court registration
• bookkeeping
• business bank account
• administrative fees

Although the initial cost is not necessarily high, the regular monthly operating costs are generally higher than those of a sole proprietorship.

The Most Common Mistakes Made by New Entrepreneurs

One of the most common mistakes when starting a business is choosing a legal business structure solely based on a friend’s recommendation or the experience of other entrepreneurs. What was ideal for one type of business may not be the best option for another. In addition, many entrepreneurs underestimate the importance of quality accounting and business planning during the first year of operation. Seeking professional advice in a timely manner can help avoid unnecessary costs and administrative problems.

Practical Examples: What Should You Choose?

Freelancer or Digital Nomad

If you provide services such as programming, design, marketing, or consulting and operate independently, a flat-rate sole proprietorship is often the simplest solution.

Startup Planning Growth

If you plan to hire employees, seek investors, or develop a scalable product, a simple LLC (j.d.o.o.) is usually the better choice.

Craft and Service Activities

For construction, repair, or artisanal trades, a sole proprietorship is still the most common choice due to its simpler business operations.

How Can a Coworking Space Help New Entrepreneurs?

Regardless of whether you choose a sole proprietorship or a simple LLC (j.d.o.o.), one of the first challenges will be organizing your business and finding a professional workspace.

Coworking spaces offer a range of benefits:

• a professional business address
• flexible rental terms
• meeting rooms
• networking events
• training sessions and workshops
• administrative support

For freelancers and startups, this represents significant savings compared to renting a traditional office.

In addition to lower costs, the coworking community enables meeting potential clients, partners, and collaborators, which can accelerate business development.

Does a New Entrepreneur Need Office Space?

In the first months of business, many entrepreneurs try to reduce costs and work from home or remotely. However, as the business grows, the need arises for a professional space for meetings, client presentations, and building a business network. That is why more and more freelancers, sole proprietors, and startups choose coworking spaces, which offer a more flexible and financially affordable solution than traditional office rental.

In addition to fulfilling certain administrative requirements, a business address contributes to brand credibility and creates a more professional image of the company. For many new entrepreneurs, coworking spaces represent a practical solution that combines a business address, workspace, and access to a business community.

Conclusion: Sole Proprietorship or Simple LLC (j.d.o.o.)?

There is no universal solution that fits everyone.

If you are looking for a simple start, less administration, and lower costs, a sole proprietorship can be an excellent choice. If you want to protect personal assets, build a more serious company, and plan for growth, a simple LLC (j.d.o.o.) often represents a safer long-term solution.

Before making a final decision, it is advisable to consult an accountant or business advisor to choose the legal structure that best matches your goals, income, and development plans.

Conclusion: Sole Proprietorship or Simple LLC (j.d.o.o.)?

There is no universal solution that suits all entrepreneurs.

From experience working with freelancers, startups, and small business owners, it is evident that most entrepreneurs in the early stage of business choose a sole proprietorship or a flat-rate sole proprietorship due to lower costs, simpler administration, and faster business setup. On the other hand, entrepreneurs who plan from the very beginning to hire employees, attract investors, or cooperate with larger companies more often choose a simple LLC (j.d.o.o.) or a limited liability company (d.o.o.) as a more scalable long-term solution.

If you are looking for a simple start, less administration, and lower operating costs, a sole proprietorship can be an excellent choice. If you want to protect personal assets, build a more professional business image, and create a foundation for future business growth, a simple LLC (j.d.o.o.) often represents a safer long-term solution.

It is important to emphasize that the best choice depends on the type of activity, expected income, level of business risk, and business development plans over the next few years. What is ideal for a freelancer or independent consultant is not necessarily the best solution for a startup planning to expand its team or seek investors.

Before making a final decision, it is advisable to consult an accountant or business advisor in order to assess tax obligations, business costs, and long-term goals. A timely decision on the appropriate legal structure can save you time, money, and administrative complications, and allow you to focus on what matters most – developing a successful business.
