Maxing out my 401k and 457b leave me with $37,340 in taxable income (after healthcare, and life/ad&d deductions). I expect to make about 20 - 30k net profit (before any SEP IRA contribution) through the side business this year, so I should still be under the income limit to contribute the full amount to the TIRA. If I end up doing better than that with the business, I'll find some more expenses to get me back down to the appropriate point. And if I do so well, that doing so isn't possible... well I guess that isn't a terrible problem to have.
