The W-2 Decoded: Every Box on Your Wage Statement Explained

Most workers glance at Box 1 wages and Box 2 federal tax withheld, then hand the W-2 to tax software without reading the rest. But the W-2 has over twenty boxes, and understanding them reveals whether your employer withheld correctly, how much you contributed to Social Security, whether your retirement plan contributions went in properly, and what your health insurance actually cost pretax. This episode decodes every box: the three-way wage split between Box 1, Box 3, and Box 5; the coded Box 12 entries for 401 k, HSA employer contributions, and health insurance cost; the Box 13 checkboxes; state and local boxes fifteen through twenty; and what to do when your W-2 is wrong, including Form 4852 and IRS phone support at 800 8291040. Verify specifics with your employer or a CPA, Enrolled Agent, or VITA.
