Sole proprietor or LLC, when to switch to an LLC, transitioning from a sole proprietorship to an LLC – these questions arise as soon as a business starts to grow. Just last year, operating as a sole proprietor was the perfect solution, but today your income is approaching the simplified tax system limit, you have a business partner to share the company with, and your debts may put your own apartment and car at risk.

Those who wait until the last moment face the greatest risks: exceeding the income limit at the end of the year, bringing in a co-owner without formally defined ownership shares, or accumulating significant debts as a sole proprietor can cost you money and property. If two or three of the signs below sound familiar, your business may have already outgrown the sole proprietor format.

In this article, we will cover: 5 signs that your business has outgrown the sole proprietor format, how asset protection works in an LLC (and when it does not), how much it actually costs to “take the money out for yourself”, a step-by-step transition process with a list of common mistakes, and a comprehensive sole proprietor vs LLC comparison table. For a general comparison of which business structure to choose when starting out, see our separate article “What to choose: sole proprietor or LLC”.

5 signs your business has outgrown the simplified tax system

This is not about a vague feeling that “it might be time to grow”, but about specific facts. If two or three of them apply to you, it may already be time to consider an LLC.

1. You are approaching the Group 3 income limit. In 2026, the annual income limit is UAH 10,091,049 (Tax Code of Ukraine, Art. 291.4). Once you exceed it, you pay 15% on the excess amount and must switch to the general taxation system. It is better to plan the transition yourself than to deal with it in a panic at the end of the year. What to do if you exceed the limit is explained in the article “Exceeding the income limit for sole proprietors”; we have also explained separately how to calculate it.

2. You are bringing in partners or investors. A sole proprietorship can only have one owner: you cannot formally allocate ownership shares, add a co-owner, or properly divide profits between several owners. An LLC has share capital and ownership interests – two or three partners can officially own the business in agreed proportions, while an investor can acquire an ownership stake.

3. Protection of personal assets. This is the most important sign. A sole proprietor is liable for business debts with all personal assets, while an LLC generally answers for its obligations with the company’s own assets. This distinction is so important that we discuss it in a separate section below.

4. Large contracts and tenders. Corporate clients, retail chains, and participants in public procurement procedures (Prozorro) often prefer to work with a legal entity, sometimes specifically with a VAT-registered company. Operating as a sole proprietor can simply close the door to some of these contracts.

5. Scale and structure. Multiple business lines, a large team, and a more complex organizational structure are generally easier to manage through an LLC.

Asset protection: when an LLC protects you and when it does not

This is the main advantage of an LLC – and at the same time one of the most overestimated. Let us look at how it actually works.

Basic rule: the company is liable for its debts, not the owner

A legal entity is independently liable for its obligations with all property that belongs to it, while its participants are generally not liable for the company’s debts (Civil Code of Ukraine, Art. 96). For LLCs, this is also confirmed by the Law of Ukraine “On Limited and Additional Liability Companies” No. 2275-VIII: the company is liable with its own property (Art. 3), while the owner generally risks only their ownership interest (contribution) in the share capital. Compare this with a sole proprietor who, under Civil Code of Ukraine, Art. 52, is liable for debts with personal property, including an apartment, car, and savings.

Limited liability is not absolute. The personal assets of an owner or director may still be at risk in the following situations:

• Causing insolvency or bankruptcy. If a company becomes insolvent due to the actions of its owners or management, they may be held subsidiarily liable for the LLC’s debts (Code of Ukraine on Bankruptcy Procedures, Art. 61) – meaning the debt may be recovered from their personal assets.
• Unpaid capital contribution. If a participant has not fully paid their contribution to the share capital, they may be liable for the company’s debts within the amount of the unpaid contribution (Law No. 2275-VIII, Art. 2).
• Personal guarantee. This is one of the most common cases in practice: banks often require the owner to provide a personal guarantee for an LLC loan. Once you sign it, you become personally liable under the guarantee agreement regardless of the company’s limited liability protection.
• Asset stripping. Deliberately transferring assets out of the company to avoid creditors may also create grounds for personal claims against those responsible.

Conclusion: limited liability works as long as the business is operated in good faith. The larger the turnover, the more important it becomes to structure and document everything properly instead of relying on an LLC as a form of “complete immunity”.

Advantages and disadvantages of an LLC compared with a sole proprietorship

To put it simply, an LLC is not an upgraded sole proprietorship, but a different business structure with its own advantages and costs.

Important: this last point is often the biggest psychological adjustment after operating as a sole proprietor. As a sole proprietor, you earn money and can freely withdraw it from your account. In an LLC, the profit belongs to the company, and you cannot simply “take it for personal needs”.

LLC share capital: minimum amount, deadlines, and contribution procedure

Another issue that often seems intimidating at the start, although it is actually quite simple (Law No. 2275-VIII):

• There is no minimum amount. The founders determine the amount of the share capital themselves – it can even be a symbolic sum. However, an excessively small capital may reduce the confidence of counterparties and banks.
• The contribution deadline is 6 months from the date of state registration (Art. 14), unless the company’s charter provides for a different period.
• Contributions can be made not only in cash (Art. 13), but also in the form of property, equipment, or securities. A non-cash contribution requires a monetary valuation approved by all participants.
• Late contribution (Art. 15): first, the participant receives a notice and an additional period of up to 30 days. After that, the general meeting decides what happens to the ownership interest, including possible expulsion of the participant, reduction of the share capital, and other measures.

Important: contributing property to the share capital is an investment in exchange for an ownership interest, not a sale, so for the LLC it is not treated as income. However, the tax consequences, including VAT and personal income tax, depend on what property is contributed and by whom – this should be calculated separately with an accountant before the transaction.

How much does it cost to “take the money out”: sole proprietor vs LLC in numbers

First, an important clarification: a sole proprietor is taxed on revenue, while an LLC under the general taxation system is taxed on profit, so this comparison is approximate. Still, it clearly illustrates the difference. Suppose a company earns UAH 1 million in net profit and the owner wants to take that money for personal use.

The key difference is that in an LLC, profit is taxed twice – first at the company level (18% or 3%/5%), and then when dividends are paid to the owner (5% or 9% personal income tax + 5% military levy, Tax Code of Ukraine, Art. 167.5). A sole proprietor does not have this second level of taxation: once the applicable business taxes have been paid, the money can be used personally without a separate withdrawal tax.

Conclusion: taking money for personal use is almost always cheaper as a sole proprietor. That is why businesses usually switch to an LLC not to save on taxes, but for asset protection, partnership opportunities, and scalability. The available ways to withdraw money from an LLC and their costs, including salary, dividends, and accountable funds, are explained in the article “How to withdraw money from an LLC”.

How to switch from a sole proprietorship to an LLC: step-by-step process

Many entrepreneurs ask whether they need to close their sole proprietorship before opening an LLC. In fact, they do not – the two business structures can exist at the same time.

One of the biggest misconceptions among entrepreneurs is: “I will convert my sole proprietorship into an LLC.” That is not how it works. A sole proprietor and an LLC are two different legal entities or business statuses, and one cannot simply be converted into the other. In practice, a new LLC is registered, business operations are transferred to it, and the sole proprietorship is either closed or retained for a separate business line. Here are the steps:

1. Register a new LLC. This requires a founders’ resolution or meeting minutes, a charter (a model charter may be used), and registration in the Unified State Register – through a state registrar, a notary, or online via Diia. State registration of an LLC is free and usually takes up to 1 business day (see how to do it in the article “How to register an LLC”).
2. Registration with the State Tax Service and the Pension Fund is completed automatically under the “single window” principle after the entry is made in the Unified State Register.
3. Choose the taxation system – apply for the Group 3 simplified tax system if you meet the income limit and activity requirements, or remain under the general taxation system with 18% corporate income tax.
4. Open a new bank account for the LLC – the sole proprietor’s account cannot be transferred to the company.
5. Register for VAT – if required (after exceeding the applicable UAH 1 million threshold or voluntarily if counterparties require VAT invoices).
6. Re-register contracts with clients and suppliers – they do not transfer automatically; new agreements or supplementary agreements replacing the contracting party with the LLC must be signed.
7. Re-register RRO/PRRO cash register systems – the sole proprietor’s cash register equipment does not transfer to the LLC: the sole proprietor deregisters their RRO/PRRO, while the LLC registers its own.
8. Transfer employees – legally, this means terminating their employment with the sole proprietor and hiring them by the LLC: new employment agreements, employment orders, and notification to the State Tax Service before they begin work.
9. Reissue licenses and permits – they do not transfer automatically and must be obtained by the LLC as a new legal entity. This is often the longest stage, so it should be planned in advance.
10. Transfer assets to the LLC – either as a contribution to the share capital in exchange for an ownership interest or through a sale from the sole proprietor to the LLC (each option has different tax consequences).
11. Decide what to do with the sole proprietorship – close it once the business has been fully transferred or keep it for a separate, smaller business line.

As for timing: LLC registration takes about 1 day, while transferring the entire business, including contracts, bank accounts, employees, RRO/PRRO systems, and licenses, usually takes from several weeks to several months. Licenses are often the main bottleneck. That is why the transition should be planned in advance rather than during the final week before exceeding the income limit.

Sole proprietor vs LLC: comparison table

Not every business needs an LLC. If your income is well below the limit, you operate independently without partners, there are no significant risks to your personal assets, your contracts are relatively small, and your clients are comfortable working with a sole proprietor, an LLC may simply add accounting costs and make it more difficult to access profits without providing meaningful benefits in return. In this situation, a sole proprietorship is simpler, cheaper, and completely legal. You can continue growing in this format for a long time – the opportunities available under Group 3 are explained in detail in the article “Everything about Group 3 sole proprietors”.

Common mistakes when switching to an LLC

The cost of a mistake at this stage can mean lost money, business downtime, and additional tax assessments. The most common mistakes are:

• Closing the sole proprietorship too early – before the LLC is actually operational with its bank account, contracts, and licenses in place. The result is downtime and disrupted cash flow.
• Failing to re-sign contracts with key clients and suppliers – payments and deliveries become “stuck” between the two business entities.
• Failing to settle remaining balances and receivables – outstanding settlements, inventory, and debts remain with the sole proprietor that is about to be closed.
• Artificial business splitting – using a sole proprietorship and an LLC owned by the same person and carrying out the same activity to artificially stay within the single tax income limit or avoid VAT. Without a genuine business purpose (Tax Code of Ukraine, Art. 14.1.231), this creates a risk that the arrangement will be treated as an abusive scheme and lead to additional tax assessments – see the article “Business splitting” for details.
• Failing to transfer assets to the LLC – the business operates through the LLC, while equipment or vehicles remain owned by the sole proprietor; legally, these assets do not belong to the company, which creates accounting and collateral issues.
• Assuming that RRO/PRRO systems and licenses will transfer automatically – as a result, the LLC may operate for some time without the required authorization or fiscal registration, which can lead to penalties.
