Some Texas teachers can contribute more to a 403(b) because of long service with the same eligible employer. This special 15-year catch-up is separate from the familiar age-50 catch-up, and it is not automatically available after 15 years in teaching.
The plan must allow it. Your employer and service must qualify. Your contribution history must leave room under the IRS formula. Buying extra TRS pension service credit does not, by itself, satisfy this separate 403(b) service test.
Quick answer: up to $3,000, subject to three limits
If the written plan permits the provision and you qualify, the special catch-up can increase your elective deferral limit by the smallest of three amounts:
- $3,000 for the year;
- $15,000 minus prior use of the special 15-year catch-up; or
- $5,000 multiplied by qualifying years of service with the organization, minus prior elective deferrals counted under the rule.
A result of zero or less leaves no additional room under this provision. The $3,000 is a maximum, not an automatic entitlement or employer contribution.

Which teachers can qualify?
The IRS identifies public school systems among the eligible employer types. For a Texas teacher, the important question is service with the qualifying organization maintaining the plan, not total years in the profession.
The IRS Fix-It Guide explains that the service need not be consecutive. But part-time employment and partial years require the service calculations in Publication 571. Fifteen calendar years since your first teaching job is not necessarily 15 qualifying years.
Changing schools within the same public school district does not, by itself, mean changing employers for this rule. The IRS specifically treats service at different schools in the same district as service with the same employer. A move to a different district needs separate evaluation.
| Question | What needs to be established | What is not sufficient |
|---|---|---|
| Is the employer eligible? | An organization allowed to offer this provision | Merely having a 403(b) account |
| Does the plan allow it? | Authorization in the written plan | A vendor's general statement that the IRS permits it |
| Is there enough service? | At least 15 qualifying years with the same eligible organization | Adding unrelated district employment without checking the rules |
| Is there contribution room? | A calculation using prior deferrals and prior special catch-ups | Assuming every long-serving teacher can add $3,000 |
Takeaway: Ask the district or plan administrator for a documented eligibility calculation before changing payroll deductions.
If you are still choosing an account type, start with 403(b) versus governmental 457(b) for Texas teachers. This article addresses a particular contribution provision after that choice.
How the special calculation works
Consider a hypothetical teacher with 18 qualifying years at the same eligible employer. Assume the plan permits the provision, prior counted elective deferrals total $78,000, and prior use of the special 15-year catch-up totals $6,000.
| Test | Calculation | Remaining amount |
|---|---|---|
| Annual special limit | Fixed maximum | $3,000 |
| Lifetime special limit | $15,000 − $6,000 | $9,000 |
| Underused-deferral test | ($5,000 × 18) − $78,000 | $12,000 |
The smallest amount is $3,000. That is the potential special catch-up for this example, subject to the remaining compensation and plan limits.
Takeaway: Passing the 15-year service test starts the calculation; it does not replace the other two tests.
Now suppose the same teacher had previously used $14,000 of the special catch-up. The lifetime test would leave only $1,000, so the special catch-up could not exceed $1,000 even if the annual and underused-deferral tests allowed more.
If prior counted deferrals instead equaled $90,000 for those 18 years, the underused-deferral test would be zero: ($5,000 × 18) − $90,000 = $0.
These are arithmetic illustrations, not determinations for a particular employee. The administrator must identify which prior deferrals count. The IRS guidance includes relevant employer-sponsored 403(b), 401(k), SARSEP, and SIMPLE plan deferrals, including the special catch-up but excluding age-based catch-up contributions for this test.
Special service catch-up versus age-based catch-up
The long-service provision and age-based catch-up have different purposes and limits. One does not automatically qualify you for the other.
| Provision | Main qualification | 2026 maximum additional amount | Main limitation |
|---|---|---|---|
| Special 15-year 403(b) provision | Qualifying service with an eligible organization; plan authorization | Up to $3,000 | Annual, lifetime, and underused-deferral tests |
| Age-50 catch-up | Age 50 or older by year-end; plan authorization | $8,000 | Compensation and applicable contribution rules |
| Higher age-based catch-up | Turns 60, 61, 62, or 63 during 2026; plan authorization | $11,250 instead of $8,000 | Replaces the regular age-based amount for eligible ages |
Takeaway: The $11,250 age-based amount is not added on top of the regular $8,000 age-based amount.
The IRS states that when both the service and age-based provisions apply, contributions above the basic elective deferral limit are allocated first to the special 15-year provision to the extent permitted, then to the age-based catch-up. See IRS catch-up guidance.
That ordering matters for future records. Money treated as a special 15-year catch-up uses part of its lifetime allowance, even if you thought of it as an age-based contribution.
What could that mean for contributions in 2026?
The 2026 basic employee elective deferral limit is $24,500. The following hypothetical totals assume adequate compensation, full eligibility, and a plan permitting every provision shown.
| Example employee | Basic deferral | Special service catch-up | Age-based catch-up | Illustrative employee total |
|---|---|---|---|---|
| Under age 50, full special eligibility | $24,500 | $3,000 | $0 | $27,500 |
| Age 55, full special eligibility | $24,500 | $3,000 | $8,000 | $35,500 |
| Turns 62 in 2026, full special eligibility | $24,500 | $3,000 | $11,250 | $38,750 |
Takeaway: These are conditional 2026 examples, not contribution limits for every Texas teacher. A lower special allowance or compensation restriction reduces the total.
Employer contributions and the separate annual-additions limit must also be checked. For 2026, the general annual-additions limit is the lesser of $72,000 or 100% of includible compensation for the employee's most recent year of service. The special 15-year amount is not the same as the age-based catch-up for applying these limits.
IRS annual adjustment tables confirm the 2026 figures. Do not reuse them as 2027 limits without checking the applicable year's official publication.
Check the Roth requirement separately
For 2026, IRS guidance states that participants subject to the Roth catch-up requirement must make age-based catch-up contributions on a Roth basis when prior-year wages with the plan sponsor exceeded $150,000. Ask payroll how this applies to your wages and plan.
Do not use total household income or TRS pension service credit as a substitute for that wage test. Also do not assume that the special 15-year provision and the age-based provision have identical Roth treatment merely because both are commonly called catch-ups.
What records should you request?
Before increasing deductions, ask for the plan provision, qualifying service calculation, history of elective deferrals counted in the test, previous use of the special provision, and the payroll allocation between service-based and age-based amounts.
If you changed vendors within the district, an empty new vendor account does not establish a fresh lifetime allowance. Prior contributions still need to be considered. If you changed districts or worked part-time, ask the administrator to resolve employer identity and credited service instead of combining years yourself.
Keep the calculation with your annual contribution records. If an error is discovered, contact the administrator promptly about the correction process. This guide does not authorize withdrawing an excess amount without plan instructions.

Frequently asked questions
Is the special catch-up automatic after 15 years of teaching?
No. The employer, written plan, qualifying service, prior contributions, and remaining special allowance must satisfy IRS requirements.
Can I combine years from different school districts?
Do not assume so. The rule concerns qualifying service with the same eligible organization. Ask the administrator to evaluate your employment history and any applicable employer rules.
Does buying TRS service credit qualify me?
A TRS pension service-credit purchase does not by itself establish qualifying service for this separate 403(b) provision. The plan administrator must apply the IRS service rules.
Can I use both the 15-year and age-based catch-ups?
Yes, when eligible and the plan permits both. Amounts above the basic deferral limit are applied first to the available special 15-year provision, then to the age-based catch-up.
Is the $15,000 allowance renewed every year?
No. It is a lifetime special allowance with the employer, reduced by prior use. The annual special increase is also limited to $3,000 and the underused-deferral calculation.
Can a teacher turning 62 add $8,000 plus $11,250 in 2026?
No. The higher $11,250 age-based catch-up replaces the regular $8,000 amount for eligible participants turning 60 through 63. A separate special service catch-up may also apply if its requirements are met.
