A potential downside of tax-deferred saving through a traditional retirement plan is that you’ll have to pay taxes when you make withdrawals at retirement. Roth plans, on the other hand, allow tax-free distributions; the tradeoff is that contributions to these plans don’t reduce your current-year taxable income.

Unfortunately, modified adjusted gross income (MAGI)-based phaseouts may reduce or eliminate your ability to contribute:

• For married taxpayers filing jointly, the 2015 phaseout range is $183,000–$193,000.
• For single and head-of-household taxpayers, the 2015 phaseout range is $116,000–$131,000.

You can make a partial contribution if your MAGI falls within the applicable range, but no contribution if it exceeds the top of the range.

If the income-based phaseout prevents you from making Roth IRA contributions and you don’t already have a traditional IRA, a “back door” IRA might be right for you. How does it work? You set up a traditional account and make a nondeductible contribution to it. You then wait until the transaction clears and convert the traditional account to a Roth account. The only tax due will be on any growth in the account between the time you made the contribution and the date of conversion.
