401(k) Administration in San Antonio, TX

San Antonio employers do not usually have a 401(k) problem — they have an unassigned-responsibility problem. The recordkeeper holds the money, the advisor picks the funds, and the plan document quietly names the business owner as plan administrator. That signature is where the personal liability sits. Admin316 takes it: we are appointed as your ERISA 3(16) plan administrator and 402(a) named fiduciary, we run the compliance calendar, and we sign and file the Form 5500.

San Antonio is a two-hour drive from our Corpus Christi office, so on-site plan committee meetings are a same-day trip when a sponsor wants one.

Why San Antonio employers call us

Government contractors and defense services

Contract award and ramp-down cycles create sharp headcount swings, which drive eligibility, vesting and partial-termination analysis. Service Contract Act fringe dollars flowing into a plan need careful compensation handling.

Healthcare systems, clinics and dental groups

Mixed W-2 and contracted provider populations plus multiple related entities raise controlled-group and coverage-testing questions that get missed until an audit.

Hospitality, tourism and food service

High turnover and tipped compensation make long-term part-time employee tracking and auto-enrollment mechanics genuinely hard. Missed deferral opportunities here are expensive to correct.

Insurance, financial services and professional firms

These sponsors typically already have a good advisor and recordkeeper, and still have no one who will sign as named fiduciary. That is the gap we fill.

The three findings that generate the most sponsor pain in Texas plans: late deferral deposits (the DOL treats employee money not deposited as soon as administratively feasible as a prohibited transaction), missed deferral opportunities for newly eligible or long-term part-time employees, and Form 5500 filings that do not reconcile to the trust statement. All three are correctable — and all three are cheaper to fix voluntarily than to be found with.

How onboarding works

1. Discovery call (20 minutes)Plan document, participant count, payroll cadence, recordkeeper, and any known issue you are worried about.
2. Plan reviewWe read the actual document and the last two Form 5500 filings, and tell you plainly what is out of alignment.
3. AppointmentWe are named as 3(16) administrator and 402(a) named fiduciary by board resolution and plan amendment.
4. Ongoing administrationPayroll-cycle monitoring, notices, testing, filings, and one point of contact who answers.

Questions San Antonio plan sponsors ask

Is a 3(16) administrator the same as a TPA?
No. A third-party administrator performs the work but the employer stays legally responsible as plan administrator. A true 3(16) administrator is appointed in the plan document and accepts that fiduciary responsibility in writing. Admin316 does both roles: TPA work plus signed 3(16) and 402(a) appointment.
Do we have to change our recordkeeper or advisor?
No. We sell no investment products and take no commissions, so we work alongside whichever recordkeeper, payroll provider and advisor you already use.
Who signs the Form 5500?
We do. As your appointed 3(16) administrator, Admin316 signs and files the Form 5500 and delivers the participant notices on the statutory calendar.
What if we already have a compliance problem?
Bring it. Late deferral deposits, missed deferral opportunities, blown testing and unfiled 5500s are all correctable through the IRS and DOL programs (EPCRS, VFCP, DFVCP). Voluntary correction is dramatically cheaper than being found.
How much does it cost?
It depends on participant count, payroll frequency and plan design, so we quote after a short discovery call rather than posting a number that will not match your plan.
Do you only work with San Antonio employers?
No. Admin316 serves plan sponsors nationwide from Corpus Christi, Texas. We do have concentrated San Antonio and Texas experience, and New Braunfels and the surrounding area are routine for us.
