RTT may label a TIAA-linked base retirement contribution. The name does not identify a 401(k), 403(b) or other plan without the employer’s documents.
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 Base 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 $120 RTT row can describe an employer contribution while a separate voluntary deduction funds another part of the plan.
Examples illustrate the checking method. They are not a personal tax calculation or a promise of a particular benefit.
What to check with payroll
Check the payer, plan type and whether the amount is mandatory, matching or discretionary.
