What This Means for Employers
For a business hiring at a $60,000 salary, choosing Illinois over Connecticut saves $967 per employee per year in employer-side payroll costs alone. For a team of 10, that's $9,671 annually — enough to fund an additional hire or significantly offset operating costs.
The biggest difference comes from SUTA (state unemployment tax) — Connecticut charges 2.9% on the first $27,000 vs Illinois's 2.75% on $14,250. The rate difference of 0.15 percentage points is significant because SUTA is levied on every employee and adjusts annually based on your unemployment claims history. Federal taxes — Social Security (6.2%), Medicare (1.45%), and FUTA (0.6%) — are identical in both states and account for the majority of employer tax burden.
A notable difference between these states is mandatory benefit programs. Connecticut requires employer contributions to paid family leave programs that Illinois does not mandate — adding $300 per employee annually.
These numbers reflect employer-side costs only and don't include benefits, overhead, or the employee's own tax burden. Use the interactive Employee Cost Calculator to model different salary levels and benefits packages.
Choosing Between Connecticut and Illinois?
Cost alone favors Illinois: At a $60K salary, you save $967 per employee — a real number that compounds across a growing team. At 20 employees, that's $19,343/year before factoring in any raises.
When Connecticut might still make sense: If your business depends on talent concentrated in Connecticut — tech workers, finance professionals, specialized trades — the labor market access may outweigh the payroll cost premium. Remote-friendly roles, however, make the $967/employee savings a strong argument for Illinois-based registration.
What this comparison doesn't capture: State income tax (employee side) affects your offer competitiveness — employees in high-tax states need higher gross pay to net the same take-home. Connecticut has state income tax; Illinois has state income tax. This affects what salary you need to offer to attract equivalent candidates.
