Understand this route
Check the conditions for preferential ZUS contributions after the start period and their limits.
What to do
1. Establish whether Ulga na start has ended and whether the former-employer exclusion applies.
2. Check the current calculation and notification in the official ZUS service.
Preferential contributions
After start relief, or where it does not apply, check the 60-month business history, the link with a former employer and the exact start date. Preferential social contributions can apply for 24 full calendar months; health contributions have separate rules.
Action
Verify the notification form, contribution base and end date with ZUS; the preferential regime is not determined only by a service label or one client.
