How a Mississippi paycheck is built
Every Mississippi 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.
Mississippi adds a flat state income tax of approximately 4.40 percent. Verify the current rate with the Mississippi Department of Revenue.
