The Thrift Savings Plan  started a participant poll Wednesday on what financial services they value most and how the 401(k)-style program could to help them feel confident about their expected retirement income.

The brief online survey, the first in what is to be a series, asks participants to pick the three services they like most from financial institutions such as banks or mutual fund companies. Choices include financial education, advice and counseling, compatibility of account information with other financial software, and access to accounts through mobile devices and social media.

Legislation is required to make major changes in the TSP such as the addition last year of Roth-type investing, but day-to-day aspects of the program such as customer service features are within the self-funding agency’s own control.

Federal employees and uniformed personnel may invest in the TSP, while those separated for retirement or other reasons may keep their accounts open although they may not make additional investments.
