People who file taxes as single or head of household will be able to contribute the full $5,500 (or $6,500 if they're 50 or older) to a Roth IRA in 2018 if their modified adjusted gross income is less than $120,000, and the contribution amount will phase out completely if they earn more than $135,000 (up from $118,000 to $133,000 in 2017). Married couples filing jointly will be able to contribute the full amount if their modified adjusted gross income is less than $189,000, with the amount phasing out above $199,000 (up from $186,000 to $196,000 in 2017).
