2. Time periods without entitlement to wages
Enter the information from line 5 of your employment tax statement here:
"Periods without entitlement to wages"

Enter the number of periods without entitlement to wages indicated under the number "U" (interruptions) (permissible values: 1 to 99).
Such a period exists if there was no entitlement to wages for at least five consecutive working days. The employer marks these periods with the capital letter "U".
No interruption are tax-free wage replacement benefits such as maternity pay, short-time work allowance or bad weather allowance. These are therefore not entered.
The tax office checks as part of the income tax return whether and which benefits were paid to you during an interruption period.
