When do preferential ZUS contributions end?

Preferential ZUS lasts 24 full months. This means that if the entrepreneur started his activity on the first day of a given month, after 24 months he should start paying the "large Social Insurance Institution".

Example 1.

The activity started on 01/03/2019.

Preferential ZUS contributions will cease to apply on February 28, 2021. Therefore, the first contribution is payable on general terms for March 2021 (the payment deadline is April 10 - for entrepreneurs not employing employees).

Example 2.

The activity started on March 8, 2020.

Since the preferential ZUS contributions cover a full 24 months, if the activity was started during the month, the preferential ZUS will be in force until the end of March 2022. So in this case, the "large ZUS" entrepreneur is only valid in April (paid until May 10 - at entrepreneurs without employees). So if the 24-month period expires during a given month, the entrepreneur pays premiums for the entire month at preferential rates.

What are the procedures for switching from preferential to essential rates?

The entrepreneurs should remember that after the end of the ZUS preferential period, there is a need to deregister with ZUS from the existing insurance code on the ZUS ZWUA form. The reason is code 600 - another reason for de-registration. After deregistration within 7 days from the beginning of the month in which full ZUS is in force, you must re-register (ZUS ZUA form) as entrepreneurs paying contributions on a standard basis. This is due to the change of the insurance code.

Preferential social security contributions and suspension of activity

Entrepreneurs who suspended their activity during the first 24 months of activity must remember that the period of suspension does not extend the period of preferential ZUS. The tax relief period is then 24 months, including the periods in which the activity was suspended.

Every person running a business who benefits from preferential ZUS should keep an eye on the 24-month deadline and after that, start the procedure of re-registration into full contributions. The Social Insurance Institution is not obliged to remind the entrepreneur about this.
