A ZUS inspection of a healthcare provider requires a comparison of contracts, payments and the way doctors actually work. A complete HR file is insufficient if rotas, transfers and instructions show a different working arrangement. Preparation should therefore begin by identifying the people, periods and issues covered by the inspection. ZUS is Poland’s Social Insurance Institution.
This guide is for clinic owners, healthcare company boards, HR teams and accountants. It explains the stages from the inspection notice to the findings report and any subsequent decision. An inspection does not necessarily lead to a dispute. However, properly organised evidence makes it easier to explain the provider’s contribution calculations.
Law stated as at 28 September 2026. The inspection’s scope follows from the authorisation and the applicable legislation.
What can a ZUS inspection cover?
ZUS may examine compliance with social-insurance obligations. Article 86 of the Social Insurance System Act covers, among other matters, registration for insurance, the calculation and payment of contributions, and the determination and payment of benefits. The inspection can also concern records needed for benefits and specified insurance data.
For healthcare providers, additional shifts, simultaneous employment and a separate contract, intermediary arrangements and service payments deserve particular attention. However, do not assume that the inspector challenges every B2B contract. First identify the actual scope of the examination and the basis for requesting each document.
Professional authorisation requires a separate assessment. A valid medical licence, known as PWZ, does not determine the insurance category or contribution base. Equally, a contribution dispute does not replace checking qualifications, residence rights or supervision. For foreign specialists, our guide to PWZ documents for non-EU medical specialists explains that separate documentation.
After the notice: identify the scope and responsible people
Read the notice and then the inspector’s authorisation. Record the delivery date, scope, expected inspection period and inspector’s details. Also check the authority of the person representing the provider. An external accounting firm does not automatically assume all the contribution payer’s responsibilities.
Chapter 5 of the Entrepreneurs Act applies when the inspected contribution payer is an entrepreneur. As a general rule, the inspection starts after seven days and before thirty days have elapsed from delivery of the notice. However, the Act contains exceptions and permits an earlier start at the entrepreneur’s request. Check the provider’s status before applying these rules to an entity that is not an entrepreneur.
Appoint one coordinator. HR should prepare contracts and registrations, accountants should prepare payment records, and the medical director should explain how work is organised. Next, agree how documents will be supplied and keep a register of requests and replies. This helps different departments avoid giving inconsistent accounts of the same event.
Documents to prepare for a ZUS inspection
Prepare a list of the doctors and other individuals within the inspection’s scope. For each person, identify the engagement period, contract type, any concurrent employment, insurance category and payment method. Then connect those details with the underlying records.
| Area | Examples of records | What to compare |
|---|---|---|
| Basis of the engagement | Contracts, amendments, duties and shift orders | The written agreement and actual responsibilities |
| Payments | Payroll, invoices, payment confirmations and ZUS reports | The period, amount, recipient and contribution base used |
| Working arrangements | Rotas, substitution rules and availability agreements | Who determines the time, place and method of work |
| Intermediaries | Agreements between entities and service settlements | Who actually benefits from the doctor’s work |
Do not create documents after receiving the notice that pretend to record earlier arrangements. If an amendment is missing or records conflict, describe the position accurately. The chronology can be reconstructed from existing evidence. However, documents must not be backdated, and statements must not misrepresent what happened.
Keep copies supplied to the inspector separate from working spreadsheets. Label each version, date and data source. If the accounts team corrects a spreadsheet error, retain the explanation. This allows the provider to distinguish a technical mistake from a different legal assessment.
Doctors’ contracts: actual performance also matters
A ZUS inspection may require the provider to explain how a contract was performed. A “B2B cooperation” heading, CEIDG business registration and invoices do not settle the issue. Relevant factors include subordination, working-time arrangements, substitution and the parties’ responsibilities.
A separate issue arises where a doctor is an employee and also has a civil-law contract with their employer. Article 8(2a) of the Social Insurance System Act also covers the contracts listed there when made with another entity, if the work benefits the person’s own employer. Therefore, identify the actual beneficiary of the work, rather than looking only at the invoice issuer.
Not every feature of clinical organisation establishes an employment relationship. A rota may ensure continuity of care, while procedures protect patient safety. Nevertheless, assess the entire arrangement, including the actual freedom to agree availability and perform the contractual obligation. If a dispute arises, the records should explain those distinctions with concrete facts.
Inspection procedure and protection of patient data
The inspector has statutory powers to examine documents, request explanations and obtain evidence within the inspection’s limits. The provider should cooperate while checking the connection between the requested information and the inspection. Automatically handing over the entire patient database is inappropriate. So is refusing every clinical document without examining the legal basis.
If a request includes health data, establish the precise legal basis, purpose and necessary scope. Ask for clarification where the request is unclear. Then agree secure disclosure arrangements with the person responsible for data protection. A financial schedule may sometimes answer the question without disclosing the full clinical history.
When providing explanations, distinguish personal knowledge from information supplied by others. Do not guess why an old correction was made or how another department organised its work. Instead, identify a record or person who can reliably explain that point.
How long can a ZUS inspection last?
The Entrepreneurs Act sets annual limits for inspections by one authority: six working days for a micro-enterprise, eighteen for a small enterprise, twenty-four for a medium-sized enterprise and forty-eight for other businesses. The statutory criteria determine the category. The number of doctors on the rota alone is insufficient.
Exceptions apply. In addition, Article 55(6a) permits a special extension for a micro-enterprise where, after the on-site work, only document analysis and preparation of the report remain. Under that provision, the total cannot exceed twice the basic limit. Therefore, it would be incorrect to promise that every inspection of a small clinic must end after six days.
An entrepreneur may lodge a reasoned procedural objection against specified breaches of inspection rules. The deadline is three working days from the start of the inspection or the occurrence of the grounds for objection. The objection goes to the authority, and the inspector must be notified. Article 59 governs suspension and its exceptions. This remedy differs from later objections to the findings report.
The report, corrections and an appeal are separate stages
After receiving the report, compare each finding with the evidence and the cited legal basis. The general deadline for objections to the report’s findings is fourteen days from receipt. The payer should identify the supporting evidence at the same time. A statement that “the contracts were correct” is too general.
The Act also provides for objections to an annex. However, it excludes further objections to an annex produced following consideration of earlier objections. Check which document you have received. Keep proof of delivery and do not confuse the date on the document with the start of the deadline.
Corrections to insurance records follow separate rules. Article 41(7b) generally allows thirty days from receipt of the report, annex or notification of how objections were resolved. If the need for correction follows from a decision, the period is seven days after the decision becomes final. Article 48d and the circumstances of the particular reporting period must also be considered.
The report is not a decision. A typical ZUS decision on insurance coverage or contributions can be appealed to the competent ordinary court through ZUS. The deadline is one month from delivery of the decision, not thirty days. Review the appeal instructions, the challenged findings and any rules specific to the case type.
A preparation example and action checklist
Hypothetical example. A clinic employs a doctor and pays for additional shifts through an external company. Before the inspection, it collects both contracts, rotas, settlements between the companies and information about the beneficiary of the services. This enables an assessment under Article 8(2a). The intermediary’s assurance of “full compliance” does not replace that analysis.
- Identify the inspection’s scope, periods and representation arrangements.
- Connect contracts with rotas, payments and ZUS records.
- Explain discrepancies without altering historical facts.
- Control the scope of disclosed data and keep disclosure records.
- Separate the deadlines for procedural objections, report objections, corrections and appeals.
- After the inspection, also change the actual working arrangements if they need correction.
Frequently asked questions
Can accountants handle the ZUS inspection alone?
They can prepare payment records and act within their authority. However, the provider must help explain the actual organisation of work. A dispute about the legal classification of a contract may also require legal analysis.
Does signing the report mean accepting the findings?
Acknowledging receipt does not replace assessing the report’s contents. Exercise the right to object within the statutory period. Avoiding receipt should not be treated as a way to stop the proceedings.
Does an inspection automatically mean arrears?
No. The consequences depend on the findings and decisions. Any risk assessment should calculate contributions, interest, corrections and effects on individuals separately. The number of contracts alone cannot provide a reliable figure.
