Proportional calculation of social tax

PROPORTIONAL CALCULATION OF QUARTERLY OBLIGATION OF ADVANCE PAYMENTS OF SOCIAL TAX, IF TAX LIABILITY AROSE DURING A PERIOD SHORTER THAN A QUARTER (subsections 9 (5) and (51) of social tax act).

If the requirements for exemption from advance payments have been met not throughout the whole quarter, but during certain periods of the quarter only, it is required to apply proportional calculation.

Sole proprietors pay advance payments of social tax in proportion to:

  • the number of days of registration as a sole proprietor, if the sole proprietor has been entered in the commercial register or deleted from there during a quarter;

  • the number of days of engagement in business, if they have informed the registrar of the commercial register of the suspension of the business activities or the starting and final date of the temporary seasonal activity;

  • the number of days preceding the time of becoming a person receiving state pension or a person with partial or no work ability if they have become a person receiving state pension or a person with partial or no work ability during the quarter, and  the number of days following the termination of the status of a person receiving state pension or a person with partial or no work ability, if their right to receive a state pension or the status of a person with partial or no work ability has terminated during the quarter;

  • the number of days preceding the creation of the status of a person considered equal to an insured person on the basis of clause  5  (4) 5) of the Health Insurance Act, if their right to be such a person has been created during the quarter, and  the number of days following the termination of the status of a person considered equal to an insured person on the basis of clause  5  (4)  5) of the Health Insurance Act, if the status has terminated during the quarter;

  • the number of days of non-validity of certificate A1 issued by a foreign competent social security authority.

If tax liability arises for a person only for some days in the quarter:

  • the number of days when the tax liability arose is determined (all the days not covered with tax exemption are added up);

  • the actual number of the days of the quarter concerned is found;

  • the payment is calculated on a daily basis: quarterly payment ÷ the number of days in the quarter × the number of days of tax liability.

The number of days in each quarter is different:
I qtr: 31+28+31=90 days
II qtr: 30+31+30=91 days
III qtr: 31+31+30=92 days
IV qtr: 31+30+31=92 days

For example, tax liability arose for 50 days and there are 91 days in the quarter concerned, the tax liability is calculated as follows: 578.16 euros ÷ 91 × 50 = 317.67 euros.

Examples on the daily-based calculations of advance payments in the I quarter of 2021
(the number of days = the number of days of tax liability in the quarter; available data as at 14 March 2021):

  1. Sole proprietor's starting date 1 January 2021 (or earlier) and final date 31 January 2021 → the number of days = 31 → I qtr payment: 578.16 euros ÷ 90 days × 31 days = 199.14 euros
  2. Sole proprietor's starting date 31 January 2021 and final date 28 February 2021 → the number of days = 29 → I qtr payment: 578.16 ÷ 90 × 29 = 186.30 euros
  3. Sole proprietor's starting date 1 January 2021 (or earlier), suspension from 10 January 2021 to 5 February 2021 (27 days) and a student from 10 February to 5 March 2020 (24 days), the final date of being a sole proprietor is not mentioned → the number of days = the number of days in the quarter 90 – the number of days of suspension 27 – the number of days of being a student 24 = 39 → I qtr payment: 578.16 ÷ 90 × 39 = 250.54 euros.
