Code Section 415(n)(3) allows trustee-to-trustee transfers from 403(b) or 457(b) plans for the purchase of permissive service credits.

Code Section 402(c)(10) allows Section 457(b) plans to accept rollovers from 401(k) plans as long as such amounts are separately accounted for.

My question: Has the IRS issued guidance on whether an individual can rollover 401(k) monies into a governmental 457(b) plan and then transfer those amounts for the purpose of purchasing permissive service credits?

Thanks.
