$100,000 prior salary

Connecticut$826/wk
Illinois$859/wk

Worked example: $100,000 prior salary

Same high-quarter assumption ($25,000) in both states. The difference comes from each state's min/max clamp and maximum weeks.

How the comparison is built

  1. 1.Start with the same $25,000 high-quarter wages in both states.
  2. 2.Estimate raw weekly benefits as $25,000 ÷ 26 ≈ $961.
  3. 3.Clamp to Connecticut's $72–$826 range and Illinois's $51–$859 range.
  4. 4.Multiply by 26 weeks in Connecticut and 26 weeks in Illinois.

State rules explained

Why Connecticut and Illinois produce different unemployment results

The gap is not only one weekly number. Duration, tax treatment, and eligibility notes can change which state looks better for a given worker.

High maximum weekly benefit when dependency allowances are included.

Max WBA reflects the published maximum including dependents.

CT generally taxes unemployment benefits as ordinary state income. Federal income tax also applies.

When the higher-benefit state can change

The maximum-total winner is a useful benchmark, not a guarantee for every claimant. Review these factors before concluding that one state always pays more.

Your actual wages

Lower earners may land between each state's min and max. Connecticut floors at $72; Illinois floors at $51.

Duration vs weekly amount

Connecticut models 26 weeks and Illinois models 26 weeks. A shorter duration can erase a higher weekly maximum.

Taxes on UI

Federal tax applies in both. State treatment: taxed by state in Connecticut vs taxed by state in Illinois.

Eligibility and disqualifications

Misconduct, quitting without good cause, refusing suitable work, or failing work-search rules can reduce or deny benefits in either state.

Dependents and special allowances

Where published, max WBA may include dependency allowances. Confirm whether your household qualifies.

Part-time earnings

Partial benefits while working can change weekly amounts differently under each state's earnings disregard.

Moving between Connecticut and Illinois while unemployed

Unemployment claims are generally tied to where you earned covered wages, not only where you live after a layoff. Moving to the higher-maximum state usually does not rewrite the paying state's weekly benefit.

Questions to resolve

  • Which state(s) paid your covered wages in the base period—Connecticut, Illinois, or both?
  • Will you file a regular claim, interstate claim, or combined-wage claim?
  • Where will you seek work and certify each week?
  • Does either state require in-person reporting or local work-search rules after a move?
  • How will tax withholding and 1099-G reporting work after relocation?

Practical takeaway

Use this page to compare published maxima and tax treatment. File with the correct paying state agency for an official determination. Interstate claim logistics are handled by the state unemployment systems—not by changing your mailing address alone.

Checklist before comparing a real claim

Confirm base-period wages

Identify which employers and states paid covered wages that Connecticut or Illinois can count.

Estimate both weekly amounts

Use high-quarter wages in the calculator for each state instead of relying only on the published maximum.

Compare duration and taxes

Model 26 vs 26 weeks and whether state tax applies after federal tax.

Review separation reason

Layoff, discharge, and quit rules differ. A denial in one state does not automatically transfer.

Plan certifications

Weekly or biweekly certifications, work-search logs, and able/available status still control payment.

Keep tax documents

Save claim confirmations and Form 1099-G. Federal tax applies even when a state exempts UI.

Max weekly is a ceiling

Most claimants earn less than $826 in Connecticut or $859 in Illinois.

Duration multiplies the gap

A 0-week difference can outweigh a modest weekly gap over a full claim.

Federal tax is nationwide

UI is taxable federally in both states. State tax treatment is the variable layer.

Compare a different pair

Compare any two states

Max weekly benefit, duration, total benefits, and state tax treatment.

Estimate your weekly benefit
