Open Overtime Tax Calculator →When you work overtime in Connecticut, each extra hour is subject to federal supplemental withholding (typically 22%), FICA (7.65%), and Connecticut's graduated rate (up to 6.99%) state tax. Without local income taxes, the state rate is the only additional layer. The overtime calculator shows you the real after-tax value of overtime work with Connecticut rates, so you can decide whether extra hours are worth it.
Connecticut uses a graduated income tax with brackets ranging from 3-6.99%. Lower income is taxed at lower rates, with the 6.99% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. Connecticut does not have local income taxes, so the state graduated rate is the total state-level income tax burden.
