The TSP May Add A Tax-Free Roth Option
I don't think many employers have added the Roth 401k feature. This would be a great benefit for retirement savers, but just a few large companies offer the new Roth 401k. The Washington Post reported the Thrift Savings Plan (TSP) may add the Roth option.
Currently, TSP participants make tax-deferred contributions, and those savings plus any earnings are taxed upon withdrawal, usually in retirement. Contributions to Roth plans are made after taxes have been paid; those savings and their earnings are withdrawn tax-free. That makes a Roth option especially attractive to people who expect their income to rise over time, putting them in higher tax brackets.
