Payroll Taxes: A Beginner’s Guide

For 2026 federal payroll, employees and employers each pay 6.2 percent Social Security tax on wages up to $184,500 and 1.45 percent Medicare tax with no wage cap. An employer also withholds an employee-only additional 0.9 percent Medicare tax after wages it pays the employee exceed $200,000. Federal income-tax withholding comes from the employee’s Form W-4 and the current Publication 15-T method. FUTA is employer-only and uses a separate wage base and credit system. States can add income-tax withholding, unemployment, local wage tax, paid leave, and disability contributions.

This guide is part of Steady’s Business Taxes & the IRS 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

Payroll tax begins with worker status

Employees generally belong in payroll and receive Form W-2; a contract or LLC does not automatically create contractor status.

Gross pay is not always taxable wage

Pre-tax benefits, imputed income, reimbursements, tips, bonuses, fringe benefits, and jurisdiction rules affect each tax base.

Federal income withholding is employee-specific

Use the current Form W-4, pay frequency, taxable wages, and Publication 15-T rather than a flat guess.

FICA has employee and employer shares

Social Security and regular Medicare are generally withheld from the employee and matched by the employer.

Additional Medicare is not matched

Withhold 0.9 percent after one employer pays an employee more than $200,000 in the calendar year.

FUTA is an employer tax

Do not deduct federal unemployment tax from employee wages.

Deposits can be monthly or semiweekly

The IRS assigns schedules based on lookback liability, and the $100,000 rule can accelerate a deposit.

Quarterly and year-end forms must reconcile

Forms 941, 940, W-2 and W-3, state wage reports, payroll registers, deposits, cash, and the ledger should agree.

Step-by-step workflow

1. Register the employer. Set up federal, state, unemployment, and local accounts before payroll begins.
2. Complete controlled onboarding. Collect identity, Form W-4, Form I-9, state forms, work location, pay authorization, and bank authorization.
3. Configure taxable pay codes. Define regular, overtime, bonus, commission, tip, benefit, reimbursement, deduction, and leave treatment.
4. Calculate and review payroll. Test hours, rates, gross pay, tax bases, withholding, employer taxes, deductions, and net pay.
5. Release employee payments. Use approval, positive-pay or bank controls, and a funding reconciliation.
6. Deposit payroll taxes. Apply the assigned federal and state schedules and save payment confirmation.
7. File and monitor returns. Submit the applicable federal, state, and local forms and resolve rejections or notices.
8. Reconcile each quarter. Tie year-to-date payroll to deposits, returns, liability accounts, cash, and accounting.
9. Complete year-end reporting. Reconcile W-2 and W-3 amounts, Form 940, fourth-quarter returns, states, and employee delivery.

Worked example

A business pays an employee $4,000 in regular 2026 wages before the Social Security limit. In addition to federal income-tax withholding determined from Form W-4, it generally withholds $248 of Social Security and $58 of Medicare, records equal employer shares, and calculates FUTA and state taxes separately. It then deposits on the assigned schedule and later includes the wages and taxes in the proper returns.

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

• Treating every worker as a contractor. Analyze the actual relationship before the first payment.
• Using one taxable-wage number for every tax. Reconcile the distinct federal, state, and benefit tax bases.
• Deducting employer taxes from net pay. Employer FICA and FUTA are additional employer liabilities.
• Depositing only quarterly. The assigned deposit schedule can require earlier payment.
• Skipping state work-location review. Remote and traveling employees can create new registrations and withholding.
• Trusting payroll output without reconciliation. Tie registers to returns, deposits, W-2 totals, cash, and the ledger.

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

Payroll calendar

Track pay dates, cutoffs, approvals, deposits, returns, year-end forms, and state deadlines.

Tax-base matrix

Document how every earning, benefit, deduction, and reimbursement affects each payroll tax.

Quarterly tie-out

Reconcile gross wages, tax wages, withholding, employer taxes, deposits, returns, and the general ledger.

Notice control

Route agency mail promptly and match every notice to the return, period, payment, and acceptance.
