Best HR software for benefits administration 2026

After payroll, benefits admin is the single biggest reason small businesses buy HR software. The decision splits into two camps: platforms that act as your broker (Gusto, Justworks) and platforms that integrate with your broker (BambooHR, Rippling, GoCo). Each model has trade-offs.

Built-in broker model

Gusto, Justworks, OnPay

  • +Single relationship, fewer integrations to maintain
  • +Tighter integration with payroll deductions
  • +Justworks PEO group buying often saves 10-20 percent on premium
  • −Carrier choice limited to platform's contracted carriers
  • −Limited to states the platform is licensed in

  • +Full carrier choice across the open market
  • +Preserves established broker relationship
  • +Works in any state regardless of platform licensing
  • −Two relationships to manage (HR platform + broker)
  • −Initial broker integration setup adds 1-2 weeks of work
Time savings

Cost of manual benefits admin vs automated

A typical 25-person business managing benefits manually spends 8-15 hours per month on admin: enrolment changes, life events, COBRA, ACA reporting, payroll deduction updates. Automated benefits admin via HR software typically reduces this to 1-3 hours.

10 hrs/mo
Manual admin

Spreadsheet tracking, manual carrier portals, paper forms.

2 hrs/mo
Automated

Self-service enrolment, automated deduction sync, integrated reporting.

Time saved

8 hours per month at $50 per hour. Pays for HR software twice over.

Frequently asked questions

Which HR software has built-in benefits brokerage?
Gusto and Justworks act as licensed benefits brokers themselves, meaning you can enroll in health insurance, 401(k), and ancillary benefits directly through the platform. BambooHR, Rippling, GoCo, and OnPay integrate with third-party brokers (or your existing broker) but do not act as the broker. The trade-off: built-in brokerage is simpler but limits carrier choice; broker integration preserves choice but requires managing two relationships.
How much does benefits administration cost on top of HR software?
If you use Gusto or Justworks as your broker, benefits admin is typically included in the platform fee with no separate charge. If you use a third-party broker integration (BambooHR, Rippling), expect to pay your broker their standard 4-8 percent of premium commission. Some platforms charge a small per-employee admin fee ($2-$5 per employee per month) for benefits admin even with third-party brokers.
Can HR software handle 401(k) administration?
Most platforms integrate with 401(k) providers rather than offering their own plans. Gusto integrates with Guideline, Vestwell, and Human Interest. Rippling integrates with Empower, Vestwell, and Guideline. Justworks offers its own PEO 401(k) plan. ADP Run pushes ADP's own 401(k) plan. The integration handles automatic enrolment, contribution withholding, and reporting; the underlying plan administration sits with the 401(k) provider.
What about FSA, HSA, and dependent care benefits?
Most platforms integrate with FSA/HSA administrators (HSA Bank, Lively, WageWorks). Gusto and Justworks include FSA/HSA admin in their core platform. BambooHR and Rippling require integration setup. The functional difference for end users is minimal; setup complexity differs more.
Which platform handles open enrolment best?
Rippling and BambooHR Pro have the most polished open enrolment workflows, with comparison tools, life-event handling, and employee education content. Gusto's open enrolment is functional and well-integrated when Gusto is your broker. Justworks runs open enrolment as a guided process with PEO support. ADP and Paychex open enrolment is functional but feels dated.
Do small businesses need formal benefits admin?
Once you offer health insurance, 401(k), or pre-tax benefits, you need formal admin to comply with ERISA, ACA reporting, and Section 125 plan requirements. For very small teams (under 10 employees) the requirements are lighter but still real. HR software with built-in benefits admin shifts most of this from a manual obligation to an automated workflow, often paying for itself in administrative time saved.
