When is the deadline to contribute to retirement accounts for 2026?
For workplace plans like a 401(k), 403(b) or most 457(b) plans, employee contributions for 2026 generally have to come out of paychecks dated by December 31, 2026. For traditional and Roth IRAs, you can usually contribute for 2026 until the federal tax filing deadline in April 2027 (not including extensions). That means the next two months are the last chance to adjust workplace contributions for this year.

2026 contribution limits at a glance
According to the IRS:
- 401(k), 403(b), most 457(b) and the federal Thrift Savings Plan: $24,500 employee deferral limit.
- Catch-up for age 50 and older: an additional $8,000 for most of these plans. A higher catch-up applies to people aged 60–63 in plans that offer it.
- IRA (traditional and Roth combined): $7,500, plus a $1,100 catch-up for age 50 and older.
Roth IRA eligibility phases out at higher incomes, and traditional IRA deductibility can be limited if you or your spouse are covered by a workplace plan. The IRS publishes the exact income ranges each year.
A four-step year-end check
- Find your year-to-date contributions. Look at your latest pay stub or plan website.
- Count remaining paychecks. Most people have four to six left between now and December 31.
- Confirm your employer match. Many plans match a percentage of pay. Missing the match means leaving part of your compensation behind.
- Change your contribution rate early. Payroll changes can take one or two pay cycles to apply, so do not wait until mid-December.
Worked example: catching the match
A hypothetical employee earns $72,000 a year, paid twice a month. The employer matches 100% of contributions up to 4% of pay. She has been contributing 2% all year.
- 4% of pay is $2,880 per year; at 2% she is putting in about $1,440 and receiving only about $1,440 in match.
- With five paychecks left, raising her rate is unlikely to recover the full year's missed match, because many plans calculate the match per paycheck. Some plans offer a "true-up" at year-end — her plan documents will say.
- She raises her rate to 4% now and keeps it there for 2027, so she receives the full match going forward.
Numbers are illustrative; your plan's formula may differ.
IRAs: you have more time
If you have extra cash at the end of the year or receive a bonus in early 2027, you can still contribute to an IRA for 2026 until the April 2027 deadline. When you contribute between January 1 and the deadline, tell the provider which tax year the contribution is for.
Common mistakes to avoid
- Assuming 401(k) contributions can be made after December 31 for the prior year.
- Missing the employer match because your contribution rate is too low.
- Exceeding the limit after changing jobs mid-year — the employee deferral limit applies across all your plans.
- Contributing to a Roth IRA without checking the income limits.
- Leaving the contribution change until the last paycheck of the year.
