Retirement tax questions

Please see the following for the MAGI limits:

• IRA Deduction if You ARE Covered by a Retirement Plan at Work - 2018
• IRA Deduction if You Are NOT Covered by a Retirement Plan at Work - 2018 (deduction is limited only if your spouse IS covered by a retirement plan)

Yes, if it is nondeductible it would be better to convert the amount to a Roth IRA to avoid the hassle to keep track of nondeductible contributions in your traditional IRA.
