Which employers count as law, consulting and engineering here?

Professional, scientific and technical services (codes 541100 to 541990) excluding computer systems design, which sits in Software and IT services. Sponsors here include KPMG, Boston Consulting Group and SpaceX.

The code is the IRS principal business activity code the sponsor itself puts on Form 5500, line 2d. Medians count only plans whose Schedule H shows a positive plan-paid administrative expense (7,159 of 7,635 plans here). Plan-paid expenses exclude fund expense ratios and employer-paid bills, so every figure is a floor, not the all-in cost. Latest filing in this group received by the DOL July 24, 2026; source dataset last refreshed July 28, 2026. Full methodology
