Fill Out a W-2 Online: Employer FAQ

A business can prepare W-2 forms online using SSA’s free W-2 Online service, payroll software, an EFW2 wage-file upload, commercial filing software, or an authorized provider. The employer, not the employee, completes the W-2 after annual payroll is reconciled. The form reports identity data, wages, Social Security and Medicare wages and taxes, federal withholding, benefits, deferred compensation, and state or local fields. File Copy A with SSA, furnish employee copies securely, complete separate state obligations, and use Forms W-2c and W-3c when an accepted wage statement is wrong.

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

W-4 and W-2 are different

An employee uses Form W-4 to provide withholding elections. The employer prepares Form W-2 after wages are paid.

SSA receives Copy A

W-2 wage statements are filed with the Social Security Administration, not through the IRS information-return portal used for Forms 1099.

Ten returns can trigger e-filing

The federal threshold generally aggregates covered information returns, so fewer than 10 W-2s can still require electronic filing.

Online entry is not payroll calculation

W-2 Online can create and file forms, but the employer must first reconcile wages, taxes, benefits, and returns.

Employee and state delivery remain

Federal acceptance does not itself furnish every employee copy or complete state and local wage reporting.

Corrections use formal forms

Do not replace an accepted W-2 PDF silently. Reconcile and use the current W-2c and W-3c process.

Step-by-step workflow

1. Close annual payroll. Post regular, manual, void, off-cycle, fringe-benefit, third-party sick-pay, and prior-period correction activity.
2. Reconcile quarterly returns. Tie annual wages and taxes to Forms 941, 943, or 944 as applicable, deposits, payroll registers, and the general ledger.
3. Validate employee identity. Confirm legal name, Social Security number, address, work states, localities, and year-to-date continuity.
4. Choose the online channel. Use W-2 Online for an eligible smaller population, upload EFW2, use approved payroll software, or authorize a provider.
5. Enter or import the forms. Review every federal, benefit, deferred compensation, state, and local box against the final wage-statement worksheet.
6. Review control totals. Tie W-2 totals and W-3 summary information to annual payroll and investigate differences before submission.
7. Submit and monitor. Save the submission identifier and confirm SSA acceptance rather than stopping at a generated preview.
8. Furnish and archive. Deliver employee statements securely, complete state filings, retain consent or mailing evidence, and preserve the final accepted file.

Worked example

An employer has eight W-2s and five Forms 1099 for the year. Even though the W-2 count is below 10, the aggregate covered return count is 13, so the employer reviews the electronic-filing requirement. It reconciles the four quarters of payroll, enters the employee wage statements through an authorized electronic channel, saves SSA acceptance, furnishes employee copies, and files state wage reports. Employees do not enter their own W-2 wages into the employer system.

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

• Giving employees a blank W-2. Employees generally complete W-4; employers create W-2 from payroll records.
• Sending Copy A to the IRS. Federal W-2 wage reports go to SSA.
• Entering forms before payroll reconciliation. A polished online form can preserve wrong year-to-date balances.
• Ignoring the aggregate e-file rule. Count covered information returns together.
• Treating submission as acceptance. Monitor SSA status and correct rejected reports.
• Forgetting state and employee copies. Federal filing, employee furnishing, and state reporting are separate tasks.

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

Annual W-2 bridge

Compare employee and employer totals for wages, Social Security, Medicare, withholding, benefits, state wages, and local wages to payroll and returns.

Status register

Track prepared, reviewed, submitted, rejected, accepted, employee furnished, state accepted, corrected, and closed.

Sensitive data

Limit access to Social Security numbers, use individual accounts and multifactor authentication, and avoid unprotected email attachments.

Backup user

Maintain a second authorized person and tested access before the filing deadline.
