How Paycheck Taxes Work in Delaware
How paycheck taxes work in Delaware: Your employer withholds federal income tax based on your W-4, then Delaware state income tax using state withholding tables. Social Security (6.2%) and Medicare (1.45%) are also deducted from each paycheck. Delaware's progressive tax system caps at 6.6% for high-income earners. A notable feature of Delaware is the absence of a state sales tax, which often offsets the impact of state income tax for residents. For paycheck purposes, withholding is calculated based on gross wages minus personal exemptions, making the net take-home pay relatively competitive compared to neighboring mid-Atlantic states.
