401(k) Administration in Texas

Most Texas employers do not 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.

We have administered Texas retirement plans from Corpus Christi since 1997 — for employers in the Coastal Bend, South Central Texas, the Gulf Coast, Dallas–Fort Worth, Central Texas and the Rio Grande Valley. We sell no investment products and take no commissions, so we work alongside whichever recordkeeper, payroll provider and advisor you already use.

Where Texas plans actually go wrong

Fast-growing metros cross the audit threshold without noticing

Austin, Dallas–Fort Worth and Houston plans add headcount faster than anyone re-reads the plan document. Crossing 100 eligible participants triggers an independent audit and a far less forgiving Form 5500. We watch the count and prepare for the audit before it becomes a scramble.

Hourly and seasonal workforces break eligibility tracking

Coastal Bend, Rio Grande Valley and Gulf Coast employers run crews that churn. Long-term part-time rules and entry dates are where missed deferral opportunities are created, and those get corrected with employer money, not employee money.

Contractor and leased-employee classification creates coverage gaps

Contractors and leased employees can complicate who is actually eligible for the plan. Misclassification can create missed coverage or testing problems that need to be corrected after the fact.

Multiple entities raise controlled-group questions nobody answers

Texas owners commonly hold several LLCs, a management company and a real-estate entity. Controlled-group and affiliated-service-group rules decide who must be covered by the plan at all. A recordkeeper will not evaluate that for you.

Energy, construction and prevailing-wage work complicate compensation

Per-diems, bonuses, union and non-union crews and prevailing-wage jobs mean payroll’s definition of compensation rarely matches the plan document’s. Testing is where that mismatch surfaces.

Multi-location payroll creates remittance drift

Texas employers operating across multiple locations can see payroll remittances drift between locations or pay periods. Those small differences can create reconciliation problems and missed deferrals if nobody is watching the process end to end.

No mandate means no forced review

Texas does not require private employers to offer a retirement plan, so there is no state mandate forcing an employer to review its retirement program. That makes regular plan reviews a business decision rather than a state compliance deadline. a business decision rather than a state compliance deadline.

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.

What you can’t delegate

What never leaves you: the duty to select and monitor whoever you appoint, the duty to fund the plan and remit deferrals on time, and the duty to provide accurate payroll and census data. Delegation narrows your exposure; it does not erase it. Our breakdown of what each fiduciary role covers shows where the lines fall.

A practical starting sequence for a Texas sponsor

  1. Pull the current plan document, adoption agreement, and all amendments, and confirm who is named as plan administrator and named fiduciary.
  2. Reconcile the last twelve months of payroll deferrals against recordkeeper deposits and note every date gap.
  3. Confirm the last three Form 5500 filings were filed and signed, and that any required audit was attached.
  4. Inventory participant notices actually sent, with dates.
  5. Benchmark total plan cost — recordkeeping, advisory, administration, and investment expense — against comparable plans.
  6. Decide which duties you want to keep and which you want a professional fiduciary to accept in writing.

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 Texas plan sponsors ask

Is there a Texas state 401(k) mandate?
No. Texas has not enacted a state-run auto-IRA or private-sector retirement savings mandate of the kind adopted in some other states. Texas employers are not required by state law to offer a retirement plan, and there is no state program you must either join or certify an exemption from. Two things follow from that. First, offering a 401(k) in Texas is a competitive decision, not a compliance one — which is why plan design and cost matter more here than mandate paperwork. Second, once you do sponsor a plan, you are fully inside the federal ERISA framework, and there is no state agency softening the landing. Your regulators are the Department of Labor and the IRS.
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 serve Texas employers?
No. Admin316 serves plan sponsors nationwide from Corpus Christi, Texas. Texas is simply where our concentration is deepest, and in-state travel is routine for us.
Is there a state-level 401(k) filing in Texas?
No. Texas has no state income tax and no separate state retirement-plan filing, so your obligations are federal: the Form 5500 series, participant notices, and the ERISA fiduciary duties that attach to whoever is named plan administrator in the document.

401(k) administration for San Antonio employers

San Antonio sponsors rarely 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 owner as plan administrator. Admin316 takes that signature: we are appointed as ERISA 3(16) plan administrator and 402(a) named fiduciary, run the compliance calendar, and sign and file the Form 5500. San Antonio is a two-hour drive from our Corpus Christi office, so an on-site committee meeting is a same-day trip.

Where San Antonio plans get into trouble

  • Government contractors and defense services — award and ramp-down cycles drive eligibility, vesting and partial-termination questions; Service Contract Act fringe dollars need careful compensation handling.
  • Healthcare systems, clinics and dental groups — mixed W-2 and contracted providers across related entities raise controlled-group and coverage-testing issues that surface at audit.
  • Hospitality, tourism and food service — turnover and tipped pay make long-term part-time tracking and auto-enrollment mechanics hard, and missed deferrals are expensive to correct.
  • Insurance, financial and professional firms — a good advisor and recordkeeper are already in place, but no one will sign as named fiduciary. That is the gap we fill.
