Hi, I recently retired and have a normal non Roth TSP. I plan on rolling it over to a Vanguard traditional IRA and then gradually rolling that IRA over to a Vanguard Roth IRA over the course of the next 5 years or so (after which the Trump tax cuts are slated to expire).

But I'm hoping someone can help me with this question: I retired in Sept of 2019 and will be receiving my VSIP (separation incentive pay) this year. They treat the VSIP as payroll income and fully tax it accordingly. Since they tax it as payroll does this mean I can use this money to contribute to my Roth IRA for this year?

Thanks
