Modify contribution category or discontinue contribution

 Modify contribution category or discontinue contribution
1.    The contributor may apply for changing his choice of the contributory income category to the immediately higher or any lower one. In any of the previous two cases, the contributor must submit his application for the change before the beginning of the insurance year. The change will apply in the first month of the next year.
2.    The contributor may apply for discontinuing his contribution. The discontinuation of his contribution will apply from the first of the next month on which he requested the discontinuation, or from the date he actually discontinues payment of his contributions.

 Method of calculating pension
The retirement pension is calculated by the following formula:
(Average wage over the last two years of the contribution period × number of contribution months ÷ 480)
