Since the TSP is an employer plan, you won’t be able to participate in the Roth TSP at whatever point it becomes available. However, you still may be able to get in on a little Roth. If you have earned income and are eligible, you could contribute to a Roth IRA. You may also be able to convert old employer plan or traditional IRA into a Roth IRA. A conversion would be a taxable event, so it’s something you would do after reviewing the tax impact, now and in the future, with your tax advisor. We’re sorry you can’t jump on the Roth TSP bandwagon, but there still may be some Roth out there for you.
