Social security pensions are income-related and their amount depends on the income that is generated in parallel with TR's payments.

As a general rule, pension rights are calculated on an annual basis. If income on the income plan is increased in the middle of the year, the whole year is recalculated, including the months that have already been paid. A debt can be incurred because of the months when the income plan is changed.

Debts arising from changes in the income plan are not collected until the year-end statements are made.
