How a Connecticut paycheck is built
Every Connecticut worker pays federal income tax, calculated on the W-4 you submitted to your employer using the IRS Publication 15-T tables. Federal income tax is followed by FICA: 6.2 percent Social Security up to the annual wage base, plus 1.45 percent Medicare on every dollar. The 0.9 percent Additional Medicare Tax applies once year-to-date wages cross $200,000 single or $250,000 married filing jointly.
Connecticut adds progressive state income tax. The bracket you fall into depends on filing status and taxable income. Verify current brackets with the Connecticut Department of Revenue Services.
Paid Family Leave: Connecticut has a Paid Family Leave program with employee-paid premiums.
