The verdict
Gusto takes it, 5–1 on rounds.
There's no universal winner — Gusto keeps you in full control at a lower cost, Justworks trades some control for big-company benefits access, so decide how much that access is worth to your team before you pick.
Choose Gusto if…
- • You're a small team under ~20 employees watching costs closely
- • You want to stay the sole employer of record
Choose Justworks if…
- • You want big-company group health insurance rates for a small team
- • You're comfortable trading some HR control for shared compliance liability

- Dramatically more expensive per employee than software-only payroll

- Round 2Core Payroll & Tax FilingGusto winsGusto8/10
Automated filing, praised for accuracy
- Automatic federal/state/local filing on every tier
- Simple tier restricted to single-state filing
Justworks6/10All 50 states
Filed under Justworks' co-employer relationship
- All filing included in every plan tier
- Reviewers report 7-10 week delays on compliance document requests

Both file accurately, but Justworks' compliance document turnaround has real reported delays.
- Round 3HR Features & PEO OptionsJustworks winsGusto6/10
Toolkit model
401(k), HR pros on Premium — brokers benefits, doesn't co-employ
- 401(k) built in natively via Guideline
- No co-employment — can't unlock large-group benefit rates
Source: Gusto product data
Justworks9/10Full co-employment
Large-group medical/dental/vision via Aetna, UHC, Kaiser on Plus
- True co-employment unlocks enterprise-grade benefit rates
- Mental health and fertility benefits included on Plus
- High-risk industries (cannabis, construction, agriculture) excluded entirely

Rated easiest to learn

- Instant self-serve signup
- Advanced tools locked behind pricier Premium tier
Justworks7/109.3/10 setup ease
2-3 week onboarding with dedicated manager
- 9.3/10 G2 setup-ease score, well above ADP's 7.6
- Dedicated onboarding manager for every new account
- Requires co-employment enrollment and underwriting/eligibility review
- Several industries excluded from eligibility entirely
Source: Justworks G2 data
Justworks is fast for a PEO, but Gusto's instant self-serve signup has no underwriting step at all.
