RST may identify a TIAA-linked supplemental retirement contribution. SRA has been used for supplemental retirement annuity arrangements, but the employer’s actual plan governs.
Employer-specific label: this is a possible interpretation. Confirm the full meaning in the codebook for the employer that issued your statement.
How to read this entry
Use the possible interpretation Supplemental retirement contribution associated with TIAA alongside the column heading. An earnings amount, an employee deduction and an employer-cost memo can have different effects even when their labels look similar.
Example on a pay statement
A $75 RST deduction can be part of a voluntary retirement election. Compare it with the plan contribution record, not an annuity income payment.
Examples illustrate the checking method. They are not a personal tax calculation or a promise of a particular benefit.
What to check with payroll
Confirm the plan type, contribution election and whether a separate mandatory retirement row also appears.
