Limited liability company and Social Security - do you have to pay contributions?

The issue of social security contributions in limited liability companies is one of the most common sources of misunderstanding for entrepreneurs—especially in the case of sole proprietorships, marital partnerships, or two-person structures. In 2025, obligations towards ZUS will depend not only on the legal form of the business, but also on the relationship between the owner or partners and the company – whether they are employed, hold a position on the management board, or simply hold shares. In practice, this means that not every limited liability company pays ZUS contributions in the same way, and misinterpretation of the regulations may result in additional costs, or even an audit and arrears.

In this article, we show you exactly how ZUS settlements work in different types of limited liability companies, how the situation of a single-member company differs from that of a two-member or marital company, what forms of employment are possible for partners, and when the obligation to pay health insurance contributions arises.

Social Security contributions in a limited liability company. - basic information

Establishing a limited liability company, regardless of its location in Poland, involves paying Social Security contributions. This applies primarily to:

• Board members
• Employees of the company

Exception: In the case of shareholders of a one-person limited liability company, the situation is a bit more complex. In principle, a shareholder does not have to pay social security contributions if he is not also a member of the company's management or an employee. This means that if a shareholder does not perform work for the company and does not perform management functions, he is not subject to mandatory insurance.

Employer's obligations to Social Security in a limited liability company.

Limited liability companies (Ltd.) that employ workers have certain social security and health insurance obligations. Whether we are talking about a one-person limited liability company, a two-person limited liability company or a larger structure, these obligations are similar. Employers must pay Social Security and National Health Insurance contributions for their employees, which is an important part of the cost of doing business.

The main obligations of a limited liability company to Social Security include:

1. Payment of insurance premiums:
   • Retirement
   • Annuities
   • Disease
   • Accidental
2. Payment of health insurance premiums (NFZ).

These contributions are part of employees' salaries and are calculated on gross wages. It is worth noting that these obligations apply to both limited liability companies and sole proprietorships, although in the case of the latter, the entrepreneur pays the contributions for himself.

For a one-person limited liability company, the issue of Social Security contributions can be a bit more complicated. The owner of such a company, who is also a member of the board of directors, has to decide whether he wants to pay contributions on a general basis or can take advantage of preferential terms if he meets the relevant criteria.

It is worth remembering that in 2023 the rules regarding Social Security in limited liability companies have undergone some changes, especially in the context of the health contribution. That's why it's so important for entrepreneurs to keep abreast of changes in the rules and consult with experts on Social Security settlements.

One-person limited liability company vs. Social Security.

The issue of paying Social Security contributions in a one-person limited liability company is different from the standard situation of employees. The owner of the company, as the sole shareholder of a sole proprietorship, simultaneously serves as the board of directors. Thus, he faces several options for Social Security settlement. Choosing the right form can have a significant impact on the cost of doing business and the amount of contributions paid.

In a one-person limited liability company, the owner has the following options to choose from:

1. Employment on a contract of employment - contributions calculated on the salary
2. Contract of mandate - the owner himself is responsible for paying contributions
3. Voluntary social insurance - contributions paid on business income

Each of these options has its advantages and disadvantages. Employment under a contract provides full insurance, but comes at a higher cost. A freelance contract gives more flexibility, but requires you to pay your own contributions. Voluntary social insurance can be beneficial for those with lower incomes.

It is worth noting that, unlike in the case of a sole proprietorship, where the entrepreneur has clearly defined rules for paying Social Security, the situation is more complex in the case of a one-person limited liability company. The health contribution in a sole proprietorship is also subject to different rules than in a sole proprietorship.

Entrepreneurs often ask: "Does a limited liability company pay Social Security?". The answer is yes, but the way contributions are calculated and paid depends on the form of employment of the sole proprietor.

Social Security in a two-person limited liability company. - partners of companies

Paying Social Security contributions in a two-person limited liability company is similar to the situation in a sole proprietorship, but has its own specific aspects. The partner is obliged to carefully analyze his situation in order to choose the most favorable solution in terms of both Social Security contributions and taxes.

Partners in a two-person limited liability company have the following options:

• Employment contract or contract of mandate (when they are board members)
• No obligation to pay contributions if they are not employed and do not work for the company

It is worth noting that the situation in a two-person limited liability company is somewhat different from a sole proprietorship or a one-person limited liability company. When the partners of a two-person company serve on the board of directors and are employed by the company, they must decide whether they will work on a salaried or contract basis. This decision is crucial to the amount and method of calculating Social Security contributions.

An important aspect is that in a two-person limited liability company, as in a sole proprietorship, there is no option to pay Social Security contributions on the income earned from the business, which is possible in a sole proprietorship.

Spouses' limited liability company vs. Social Security.

A spousal limited liability company is also a specific form of business that has its own unique aspects in terms of Social Security contributions. Compared to a sole proprietorship or a standard limited liability company, the relationship with Social Security in the case of a spousal partnership has some distinctive features.

In the case of a spousal limited liability company, there is:

• No obligation to pay social security contributions as partners
• Obligation to pay contributions if spouses work for the company

This form of business can be advantageous in terms of Social Security contributions, especially compared to a sole proprietorship or a two-person limited liability company. Spouses, being partners, are not required to pay social security contributions for the mere fact of being partners. This is a significant difference from other forms of business.

However, the situation changes when spouses actively work for the company. In such a case, the limited liability company is obliged to pay Social Security contributions for them, just as for other employees. This applies to both social security contributions and health contributions.

Health insurance in a limited liability company vs. health insurance premiums

The issue of health insurance in a limited liability company is an important aspect that differs somewhat from the rules for a sole proprietorship. Understanding these differences is key to the proper operation of the company and avoiding potential problems with the Social Security Administration.

In a limited liability company, health insurance works as follows:

• It is mandatory for all those employed on a contract of employment or contract of mandate
• Company owners are not automatically covered unless they are employed by the company
• It is possible to buy voluntary insurance from the National Health Service

Unlike in a sole proprietorship, where the entrepreneur must pay the health premium for himself, the situation is more complicated in a one-person limited liability company. The owner of a limited liability company, who is not also an employee of the company, is not required to pay the health premium for the business.

However, if the owner is employed by his company (e.g., on an employment contract or contract of mandate), then the limited liability company must pay the health contribution for him, just as for other employees. This shows how important it is to correctly determine the form of cooperation between the owner and the company.

Social Security audit

Social Security inspections are an essential part of the operation of any company, regardless of its legal form. This applies to sole proprietorships as well as limited liability companies, including single-member limited liability companies. Proper preparation for such an inspection can protect the entrepreneur from many problems and potential penalties.

To avoid problems during a Social Security audit, you should:

• Organize documents in one place (contracts, payment receipts)
• Pay mandatory social and health contributions on time
• Report employees to Social Security on time

For a limited liability company, a Social Security check can be more complex than for a sole proprietorship. This is due to the fact that a limited liability company often has employees, which entails additional obligations to Social Security.

Special attention should be paid to the issue of health contribution in a sole proprietorship. Owners of such companies should carefully document their form of employment in the company, as this has a direct impact on the obligation to pay premiums.

Overdue Social Security contributions - consequences and ways of regulation

Regardless of the form of business, the consequences of not paying contributions can be severe and long-lasting.

The consequences of not paying Social Security contributions include:

• Fines and interest
• The possibility of suspending the company's activities by Social Security
• Inability to get credit
• Loss of entitlement to benefits

It is worth noting that the problem of overdue contributions applies to all forms of business. Both a sole proprietorship and a limited liability company face similar consequences if they are in arrears.

Important: The Social Security Administration can enforce arrears even years after the company is liquidated. This also applies to one-person limited liability companies that have been liquidated.

In the context of a sole proprietorship vs. Social Security, it is worth remembering that arrears may apply not only to contributions for employees, but also to the owner's contributions if he is employed by the company.

However, there is room for negotiation after a Social Security audit of the case:

• Payment in installments
• Debt restructuring

This option applies to all forms of business, including a sole proprietorship. Negotiations can help you settle your arrears without having to close your business.

It is also worth noting the issue of health premiums in a sole proprietorship. Arrears in this regard can result in the loss of the right to free health care, which is an additional argument for timely payment of obligations.
