How does a 529 plan work in Connecticut?
Connecticut does not use a standard deduction. Instead, it provides a personal exemption that phases out at higher income levels. The state also applies a tax recapture provision that increases effective rates for high earners.
Connecticut's Paid Family and Medical Leave (CT PFML) provides up to 12 weeks of paid leave at up to 95% of wages (capped at 60x minimum wage). Employee contributions are 0.5% of wages.
Connecticut has one of the highest average property tax rates in the nation at approximately 1.98%. The state has an estate tax with an exemption matching the federal level.
The minimum wage of $16.94/hr is indexed to the Employment Cost Index and adjusts annually. Tipped employees receive $6.94/hr.
Connecticut's income tax uses a complex system with both marginal rates and a 3% tax on all Connecticut taxable income for filers exceeding certain thresholds, effectively creating higher marginal rates.
