Estimated 2027 IRA and 401(k) Contribution Limits: What Retirement Savers Should Watch
The IRS has not yet announced the official 2027 retirement-account contribution limits (as of the initial publishing of this post). However, early inflation data suggests the annual contribution limit for Traditional and Roth IRAs may increase to $8,000, while the employee salary-deferral limit for 401(k) plans, including Solo 401(k)s, may increase to $25,000.
These figures are estimates—not official IRS guidance. The final numbers depend on third-quarter inflation data and are generally announced by the IRS in late fall.
For now, retirement savers can use these projections to begin planning for 2027 while keeping the confirmed 2026 limits in mind.
What are the estimated 2027 IRA and 401(k) contribution limits?
Based on currently available inflation data, the most likely 2027 limits are:
| Account type | 2026 limit | Estimated 2027 limit |
| Traditional IRA or Roth IRA | $7,500 combined | $8,000 combined |
| IRA catch-up contribution, age 50+ | $1,100 | Likely $1,100 |
| 401(k), 403(b), or governmental 457 employee deferral | $24,500 | $25,000 |
| 401(k) catch-up contribution, age 50+ | $8,000 | Likely $8,000 |
A higher 2027 401(k) limit of $25,500 remains possible, but $25,000 appears more likely based on the inflation data available so far.
Remember: Traditional and Roth IRA contributions share one annual limit. An individual cannot contribute the full limit to both a Traditional IRA and a Roth IRA in the same year.
2026 contribution limits for Traditional and Roth IRAs
For 2026, an individual may contribute up to $7,500 total to Traditional and Roth IRAs. Those age 50 or older by the end of the year may make an additional $1,100 catch-up contribution, for a total of $8,600.
Your ability to contribute directly to a Roth IRA, or deduct a Traditional IRA contribution, may be affected by your income, tax-filing status, and participation in an employer-sponsored retirement plan.
2026 SEP IRA contribution limits
A SEP IRA is generally funded by employer contributions. For 2026, the maximum SEP IRA contribution is the lesser of:
- 25% of eligible compensation, or
- $72,000
The maximum compensation that may be considered for determining a 2026 SEP IRA contribution is $360,000.
SEP IRA contribution calculations can be more complex for self-employed individuals. A tax advisor can help determine the correct contribution amount for your situation.
2026 SIMPLE IRA contribution limits
For 2026, the standard employee salary-reduction contribution limit for a SIMPLE IRA is $17,000.
Individuals age 50 or older may generally contribute an additional $4,000 catch-up contribution, for a potential total employee contribution of $21,000.
Some eligible employers may qualify for higher SIMPLE IRA contribution limits under SECURE 2.0 provisions. Employers should confirm which rules apply to their plan before communicating limits to employees or making contributions.
2026 Solo 401(k) contribution limits
A Solo 401(k), also called an individual 401(k), can allow a self-employed business owner to contribute in two roles: as an employee and as an employer.
For 2026, the employee salary-deferral limit is $24,500. Individuals age 50 or older may generally add an $8,000 catch-up contribution, bringing the potential employee contribution to $32,500.
For individuals ages 60 through 63, a higher catch-up contribution of $11,250 may apply in 2026, depending on eligibility.
In addition to employee deferrals, the business may make an employer contribution. The combined employee and employer contribution limit is generally $72,000 for 2026, before applicable catch-up contributions. The precise amount depends on the business structure, compensation, and other tax factors.
Why the 2027 limits are still estimates
Retirement contribution limits are adjusted for inflation under federal tax law. The IRS uses inflation data from July, August, and September to calculate many of the following year’s retirement-plan limits.
Early data supports a likely increase in the IRA limit from $7,500 to $8,000. The 401(k) limit also appears likely to rise, with $25,000 currently the leading estimate. Until the IRS releases its official notice, however, retirement savers and employers should treat all 2027 figures as preliminary.
Should you make a Traditional IRA contribution?
A Traditional IRA contribution may be deductible, partially deductible, or nondeductible depending on your income, filing status, and whether you or your spouse participate in a workplace retirement plan.
The right contribution strategy may also depend on whether you are considering a Roth IRA, SEP IRA, SIMPLE IRA, Solo 401(k), conversion, or other retirement-saving option.
