How line 5a connects to the rest of Part 1
The column 2 amounts on lines 5a through 5d are added on line 5e (total social security and Medicare taxes). Line 5e feeds line 6, total taxes before adjustments, along with federal income tax withheld (line 3) and any tax due under a Section 3121(q) Notice and Demand (line 5f).
Why the wage base matters
The 2026 base printed in the instructions is $184,500. Once an employee’s taxable wages and tips for the year reach that figure, you stop entering that employee’s wages on line 5a, but Medicare wages on line 5c continue without limit. The base resets each January, so the same employee can appear on line 5a again in the first quarter of the next year.
What the instructions say about sick pay
Line 5a includes sick pay paid by your agent, and sick pay paid by a third party if you received timely notice of the payments. The instructions also point to the line 8 instructions for an adjustment that may be needed on Form 941 for sick pay.
Worked example
Maria’s Cafe (a made-up employer) paid its employees $50,000 in wages subject to social security tax in the quarter, and none of them is near $184,500 for the year. Line 5a column 1 is $50,000. Column 2 is $50,000 x 0.124 = $6,200, which is $3,100 of employer tax and $3,100 of employee tax. Figures are illustrative only.
