FICA Deduction: What It Means on a Pay Stub

For 2026, the Social Security rate is 6.2 percent for the employee and 6.2 percent for the employer on wages up to the $184,500 wage base. The regular Medicare rate is 1.45 percent for each side with no wage base. An employer must withhold an additional 0.9 percent Medicare Tax from wages it pays an employee above $200,000 in the calendar year, without an employer match for that additional tax. The employee’s ultimate Additional Medicare Tax depends on filing status and the full return. Pretax benefits can affect FICA wages differently from federal income-tax wages.

This guide is part of Steady’s Payroll, W-2 & 1099 library. It explains the federal workflow in practical terms, but the correct result still depends on the payment year, entity, worker relationship, filing method, and state rules.

The answer in context

FICA contains two taxes

Social Security and Medicare use separate rates, wage rules, year-to-date limits, and pay-stub lines.

The employer match is not withheld

Employer Social Security and Medicare are additional payroll costs and liabilities.

The Social Security wage base is annual

Stop the 6.2 percent employee and employer tax when that employer’s covered wages reach $184,500 in 2026, subject to special situations.

Medicare continues

Regular Medicare has no wage base. Additional Medicare withholding begins after one employer pays more than $200,000.

Multiple employers can create a return adjustment

Each employer applies its own wage records. Excess employee Social Security tax can be addressed on the individual return when the rules are met.

Benefits change taxable wages selectively

A deduction can reduce federal income-tax wages but remain subject to Social Security and Medicare, or vice versa, depending on the plan.

Step-by-step workflow

1. Confirm gross earnings. Review regular wages, overtime, tips, bonuses, commissions, leave, taxable fringes, and adjustments.
2. Determine FICA wages. Apply the current treatment for each earning and benefit code rather than using gross pay automatically.
3. Apply Social Security. Multiply covered year-to-date wages within the 2026 wage base by the employee and employer rates.
4. Apply Medicare. Calculate regular Medicare and monitor the employer-specific $200,000 Additional Medicare withholding trigger.
5. Review the pay stub. Show clear current and year-to-date Social Security and Medicare amounts.
6. Deposit and report. Include the taxes in the correct federal deposit and Form 941 reporting process.
7. Reconcile year-end. Tie payroll registers, deposits, Forms 941, Forms W-2 and W-3, and the general ledger.
8. Correct the source. When an error is found, fix payroll calculations, tax returns, wage statements, deposits, and employee communication as required.

Worked example

An employee earns $5,000 in a 2026 pay period and has no FICA-exempt benefit affecting the wage base. Employee Social Security withholding is $310 and regular Medicare withholding is $72.50. The employer records equal matching amounts as payroll expense and liability. If the employee’s wages from this employer later exceed $200,000, the employer begins the additional 0.9 percent Medicare withholding on the excess, but does not match it.

The example is intentionally a workflow illustration, not a conclusion for every taxpayer. A strong file connects each number on the return to a source report and records why an exception, exclusion, or classification was applied.

Records to keep

Keep the source form or worksheet, contracts or engagement records, payer and recipient identity support, the detailed payment or payroll ledger, bank and processor reconciliation, calculations, correspondence about corrections, filed copies, recipient-delivery evidence, and federal and state acceptance confirmations. Store the records by tax year and keep superseded versions when they explain a correction.

A reviewer should be able to begin with the final reported amount and trace it back to transactions without rebuilding the year. Add a short review memo for judgments such as worker status, corporate exemption, payment-method exclusion, state filing, or unusual timing. That memo is often more useful than another unlabeled spreadsheet.

Common mistakes

• Calling FICA federal income tax. They are separate taxes with different wage calculations.
• Deducting the employer match from net pay. The employer share is an employer cost.
• Using last year’s wage base. The Social Security limit changes annually.
• Stopping Medicare at the wage base. Regular Medicare continues without a cap.
• Applying the filing-status threshold in payroll. The employer uses the $200,000 withholding trigger regardless of filing status.
• Marking every benefit FICA-exempt. Apply plan-specific wage treatment.

Final review before filing

Confirm the form and revision year, taxpayer identities, dollar fields, payment categories, withholding, filing channel, recipient statement, state obligations, due dates, and approval. Compare the final output with the source reconciliation rather than reviewing the form in isolation. If software recalculates an amount after an edit, rerun the tie-out.

Keep preparation, filing, and acceptance as three separate statuses. A draft can be complete but unfiled; a transmission can be sent but rejected; a federal return can be accepted while a state return is still missing. This status discipline prevents a polished PDF from being mistaken for finished compliance work.

How to handle a discrepancy

When a source form, ledger, payroll report, or software preview disagrees with another record, stop before filing and identify which amount represents the underlying transactions. Trace the difference by vendor or employee, date, invoice or payroll run, payment channel, and account. Common causes include a payment posted to the wrong year, a void recorded after a report was generated, a card payment included with checks, a duplicate import, an incorrect taxpayer name, or a late adjustment. Record the explanation and the correcting entry or form request.

Do not erase the trail by overwriting the original report. Save the first version, the reconciliation, the corrected version, and the approval. If a third party supplied an incorrect information return, request a formal correction and retain the correspondence. If a return was already transmitted, use the current correction procedure for that form and channel. A corrected recipient copy without a corresponding agency correction can leave the records inconsistent.

Federal filing is only one layer

Federal acceptance does not settle state or local obligations. A state may use a different threshold, worker test, filing portal, account number, transmittal, or due date. Some states receive eligible information through a combined program, while others require a direct submission. Verify the jurisdictions connected with the payer, recipient, employee, work location, withholding, and business activity. Save state confirmations separately so they are not hidden behind the federal acceptance.

Make next year easier

Turn the year-end work into a monthly control. Collect identity forms during onboarding, code payment methods consistently, reconcile payroll and vendor activity each month, and flag vendors or income streams that need special treatment. Schedule a fall review of missing forms, classification questions, state registrations, and electronic-filing access. By year-end, the team should be validating a maintained file instead of reconstructing twelve months of transactions under a deadline.

Practical implementation notes

Pay-stub review

Compare current and year-to-date gross pay, FICA wages, employee taxes, benefit deductions, and net pay.

Wage-base monitor

Test employees nearing $184,500 and verify migrated or acquired-company year-to-date wages when applicable.

Quarter tie-out

Reconcile Social Security and Medicare wage bases and taxes to Form 941 before filing.
