2017 IRA and 401(k) Contribution Limits: Rules, Amounts, and What Changed
In 2017, annual contribution limits for retirement plans largely stayed level from 2016, with cost-of-living adjustments affecting only certain sections. For individuals funding IRAs, the total annual cap remained unchanged at key thresholds, while 401(k), 403(b), and similar defined-contribution plans held steady at the same limits. Catch-up contribution rules for participants aged 50 and older also remained the same, as did eligibility and coverage requirements. This overview explains the amounts, how to calculate them, and how rules apply in 2017 plans.
2017 IRA Contribution Limits
For 2017, the IRA contribution limit remained at the 2016 level. The standard cap applied to both Traditional and Roth IRAs based on compensation and modified adjusted gross income (MAGI). Key rules include:
- The lesser of earned income or the annual limit for total contributions.
- Combined limits for Traditional and Roth IRAs apply across both accounts.
- Catch-up contributions allowed for those age 50 or older.
Traditional IRA Deductibility and MAGI
Whether a Traditional IRA contribution is tax-deductible depends on income and whether the individual or spouse is covered by a workplace plan. For 2017:
- Single filers: full deductibility generally phases out between $62,000 and $72,000 in MAGI.
- Married filing jointly: full deductibility phases out between $99,000 and $119,000 when covered by a workplace plan.
- Non-working spouses may contribute based on the working spouse’s compensation, subject to the same deductibility phase-outs.
Roth IRA Income Phase-Outs
Roth IRA eligibility in 2017 phased out at the following modified adjusted gross income ranges:
| Filing Status | Income Range (Phase-Out) | Rule Type |
|---|---|---|
| Single | $117,000 to $132,000 | 2017 MAGI phase-out |
| Married Filing Jointly | $184,000 to $194,000 | 2017 MAGI phase-out |
| Married Filing Separately | $0 to $10,000 | Generally disallowed if lived with spouse at any time during year |
2017 401(k), 403(b), and Similar Plan Limits
Workplace plans such as 401(k), 403(b), and government 457(b) plans followed the same annual additions cap in 2017. Participants could defer salary into the plan up to this limit, and separate employer contributions were subject to overall plan limits but not counted toward this employee deferral cap.
Defined Contribution Annual Limits
| Plan Type | 2017 Limit | Notes |
|---|---|---|
| 401(k), 403(b), 457(b) | $18,000 | Employee salary reduction contributions |
| IRA (Traditional or Roth) | $5,500 | Total contributions across both account types |
| Catch-up (age 50+, 2017) | $6,000 | Applies to 401(k)/403(b)/457(b) and IRA |
Catch-Up Contributions and Eligibility in 2017
Participants aged 50 or older could make catch-up contributions in addition to the standard annual limit. These rules were unchanged from 2016:
- 401(k)/403(b)/457(b) catch-up cap: $6,000 for 2017.
- IRA catch-up cap: $1,000 for 2017, applied on top of the $5,500 standard IRA limit.
- Eligibility required that the individual be at least 50 by the end of the 2017 plan year.
Key Takeaways for 2017 Planning
- Limits: $18,000 in 401(k)/403(b)/457(b); $5,500 in an IRA; catch-ups $6,000 and $1,000 respectively.
- Income rules: Traditional IRA deductibility phase-outs and Roth IRA phase-outs remained consistent through 2017.
- Spousal contributions: Non-working spouses may contribute to an IRA using the working spouse’s compensation, subject to the same income tests.
- Required Minimum Distributions (RMDs): Generally begin at age 70½ for most retirement plans and Traditional IRAs in 2017.
How These Limits Affect Your Savings Strategy
Understanding 2017 contribution limits helps you maximize tax-advantaged savings. If you are 50 or older, planning for catch-up contributions can substantially increase your annual savings. Coordination between workplace plans and IRAs allows you to optimize deductions and growth, while remaining within annual caps. Always verify your specific plan documents and IRS guidance for exact rules that apply to your situation, since safe harbor and integration rules vary by employer and plan type.
