Filing Tips for Connecticut
Personal exemption credits phase out at higher incomes. A 'recapture' tax can push effective rates above stated brackets. Consider the high property tax when evaluating total cost of living.
- Maximize pre-tax contributions to 401(k) ($23,500 limit in 2026, $31,000 if 50+) to reduce both federal and CT state taxable income.
- Use an HSA if you have a high-deductible health plan. Contributions ($4,400 individual, $8,750 family) are pre-tax and reduce your tax burden.
- Review your W-4. If you regularly get large refunds, adjust your withholding to keep more money in each paycheck throughout the year.

Reciprocity-pair states (PA-NJ, IL-IA, MI-OH, etc.) let you pay tax only to Connecticut.

NY, PA-Philadelphia, and other "convenience of employer" jurisdictions can override these rules. Verify your employer's state tax setup.
