A school employee with access to both a 403(b) and a governmental 457(b) has two distinct tax-advantaged plans. Their regular 2026 employee deferral limits are both $24,500, but the limits are separate. Distribution, catch-up and rollover rules differ too. First confirm that your employer offers both plans and that the 457(b) is governmental; a non-governmental 457(b) follows different rules.
Separate limits create more contribution room
For 2026, the regular elective-deferral limit is $24,500 for a 403(b) and $24,500 for a governmental 457(b). An eligible employee contributing to both may therefore defer up to $49,000 across them before catch-ups, subject to compensation, plan terms and other applicable limits.
The 403(b) employee-deferral limit is generally shared with a 401(k) and other covered salary-deferral plans in which the person participates. The 457(b) limit is generally separate. Check the year’s IRS limit and your payroll records each January; do not assume an old payroll election or article still reflects the current amount.
These are employee deferrals, not a blanket allowance for every possible employer contribution. A 403(b) has a separate annual-additions limit that includes employer contributions; governmental 457(b) plan contributions have their own plan-limit rules. If the employer contributes, ask how those dollars affect your available limit before setting a maximum payroll deduction.
| Plan feature | 403(b) | Governmental 457(b) |
|---|---|---|
| Regular 2026 employee deferral | $24,500 | $24,500 |
| Limit relationship | Generally shared with 401(k) deferrals | Generally separate from 403(b)/401(k) |
| Potential catch-ups | Age-based; optional 15-year service rule | Age-based; optional final-three-years rule |
| 10% additional tax before age 59½ | May apply unless an exception applies | Generally not for plan-native amounts; rollover sources are exception |
| What to compare | Vendor menu, total fees, employer money, plan terms | Distribution events, fees, employer money, rollover source |
Catch-up rules are not interchangeable
For 2026, eligible participants age 50 or older can generally make an additional $8,000 age-based catch-up in each plan if the plan permits it. Participants who turn 60 through 63 during 2026 may be eligible for the higher catch-up amount of $11,250 instead. Do not add both age-based amounts together.
A 403(b) may also allow a special 15-year-service catch-up for eligible employees with at least 15 years at the same qualifying employer. It has a separate annual calculation and a $15,000 lifetime cap; it is not an automatic $3,000 bonus for everyone with 15 years. Where it and an age-based catch-up both apply, IRS rules say to apply available 15-year room first, then age-based room.
A governmental 457(b) may offer a separate special catch-up during the three taxable years before the plan’s normal retirement age. It depends on unused deferral room from prior years and the plan’s rules. In a year you use that special 457 catch-up, you generally cannot also use the age-50 catch-up in that same 457 plan; use the permitted rule that produces the larger amount. Confirm catch-up eligibility with the administrator rather than combining maximum figures from different examples.
Governmental 457(b) may allow earlier access after separation
Most distributions before age 59½ from a 403(b) can be subject to ordinary income tax and the 10% additional tax unless an exception applies. One exception may apply when an employee separates from service during or after the year they turn 55, but plan and tax conditions must be checked.
A distribution from a governmental 457(b) is generally not subject to the 10% additional early-distribution tax. Ordinary income tax can still apply to taxable amounts. The exception does not generally cover money rolled into the 457(b) from another type of plan or an IRA: those rollover amounts can retain their own early-distribution treatment. Keep the source of rollover funds clear and ask how the plan accounts for them.
This difference can matter to someone separating from school employment before 59½, but it does not make 457(b) funds available at any time. The plan still sets permitted distribution events, and choosing when to draw money is a separate decision from the tax penalty.
Compare the plan menus and all-in fees
Both plans may offer mutual funds or annuity contracts, but investment menus, administrative costs, advice fees, sales charges and surrender periods depend on the employer’s plan and vendor. The SEC warns teachers not to assume an employer has endorsed a product simply because it appears on an approved vendor list. Ask each provider for the total annual cost, any charge to transfer or exit, and whether the product has guarantees or restrictions.
A governmental 457(b) is not automatically cheaper or better than a 403(b). Compare the actual investments and contracts available in your district. Read both plan documents and the fee disclosure before opening a new account or moving an old one.
Check employer money, vesting and rollover options
A school may contribute to one account, both or neither. Verify any match or nonelective contribution, eligibility date and vesting schedule. The treatment of employer contributions can differ between 403(b) and 457(b) plans, so ask the administrator how they affect the plan limit and your pay-period deductions.
If you leave the employer, an eligible governmental 457(b) balance may be left in the plan or rolled over under the plan’s rules; a direct rollover may preserve tax deferral. But moving 457(b) money to an IRA or another plan can change early-access treatment, while money rolled into a governmental 457(b) from another source does not automatically gain the governmental plan’s 10%-tax exception. Ask which rollover types the new plan accepts and how the distribution rules apply to each source before consolidating.
- Confirm your employer offers both and the 457 plan is governmental
- Check 2026 deferral room, shared 401(k) limits and catch-up eligibility
- Compare employer contributions, investments, total fees and exit charges
- Check distribution events, rollover origin and early-tax treatment
- Keep administrator confirmation with plan documents before acting
Make a side-by-side decision file
For each plan, write down: governmental or non-governmental status; regular employee-deferral limit; any 401(k) sharing; age and special catch-up eligibility; employer contribution and vesting; investment choices and all-in fees; distribution events; early-distribution tax; rollover choices; and what happens if you leave the district. If you may retire early, compare a withdrawal plan against pension and other income using a qualified tax professional where needed.
This checklist is more useful than choosing by acronym or by maximum contribution alone. The right comparison depends on which plans your employer actually offers, their fees and options, your retirement timing, and which rules apply to the money already in each account. Because the article includes 2026 limits, recheck IRS guidance and plan documents for later tax years before changing payroll elections.
