So my wife's work 401k sucks. For the privilege of investing in Vanguard's S&P 500 Index, she has to fork over 0.99% in addition to Vanguard's 0.05%. I've long been aware of the advice to "contribute up to the max match in your employer's 401k, then put the rest in an IRA." Question is, how does this work vis-à-vis taxes? In the 401k, pre-tax dollars are contributed, but for the IRA it would have to be post-tax dollars, so there must be a tax deduction or offset when we file taxes? Anybody familiar with how this works?
