Can someone summarize that part of IRS Pub 721 that allows a rollover of a US Gov annuity to an IRA (TSP) tax free? TT allow this option but does not explain why.

I read an article that explained why I can contribute pre-tax $ from my pension (annuity) but cannot find it anymore. The IRS Pub is very confusing about what is and isn't allowed. I was able to contribute a small portion of my payment to my TSP acct last year and it lowered my income and taxes and shows as "rollover" on my 1040. Any help would be appreciated.

This article from tsp.gov explains it best. It states "You can roll over money from eligible retirement plans, such as a 401(k), 403(b), or traditional IRA, to your existing TSP account". This includes annuities.
