Roth Deferral

[KevinMc]

For a small plan that allows roth deferrals a participant gave a check to the plan sponsor who then made a large contribution to her roth 401-k money source (did NOT go through payroll). Is this allowed with a roth 401-k and if not what would be the correction?

This is a post-tax voluntary contribution to the plan. Change the source in the rk system, make sure the plan permits voluntary contributions, test it with the ACP test.
