How to Complete Year-End Payroll: W-2s, 1099s, and Filing Deadlines

The IRS says the due date to file 2026 Forms W-2 with the Social Security Administration is February 1, 2027, whether you file on paper or electronically, and employees must get their copies by the same date, according to the 2026 General Instructions for Forms W-2 and W-3. The 2026 form is also different from last year’s. It has new Box 12 codes for qualified overtime, tips, and Trump account contributions, and Box 14 is now split in two.

This guide walks you through year-end payroll from the last paycheck to the final filing. You will get the 2026 deadlines, a checklist, sample W-2 math, the 1099 rules, and the penalties for missing a date.

What Is Year-End Payroll?

Year-end payroll is the set of tasks you complete after your last payroll of the calendar year. You check your records, reconcile your tax deposits and returns, prepare W-2s for employees and 1099s for contractors, and file everything with the IRS and the Social Security Administration (SSA). You also file the year’s final quarterly and annual returns.

Doing this work in December, before the deadlines are close, is the best way to avoid penalties and corrections.

What Are the Year-End Payroll Deadlines for 2026?

When a due date falls on a weekend, it moves to the next business day. January 31, 2027 is a Sunday, so most January deadlines move to Monday, February 1, 2027.

• Form 941 for the third quarter of 2026: Due October 31, 2026, which is a Saturday, so the deadline is Monday, November 2, 2026.
• Form W-2 to employees: February 1, 2027.
• Forms W-2 and W-3 to the SSA: February 1, 2027, for paper and electronic filing.
• Form 1099-NEC to recipients and the IRS: February 1, 2027. There is no automatic extension for the IRS copy.
• Form 941 for the fourth quarter: February 1, 2027. If you deposited all your taxes on time for the quarter, you generally have 10 more calendar days to file.
• Form 940: February 1, 2027, with a similar 10-day rule if you deposited all FUTA on time.
• Most Forms 1099-MISC to recipients: February 1, 2027. The IRS copy is due March 1, 2027 on paper and March 31, 2027 if you file electronically.
• ACA forms 1094-C and 1095-C: These have separate dates in March, so check the current IRS instructions.
• State returns and W-2 copies: Dates vary by state, so add each one to your calendar.

You can ask for a 30-day extension to file W-2s by using Form 8809 before the due date, but it is not granted automatically. An extension to give W-2s to employees is usually limited to 15 days and requires a strong reason.

What Should You Do Before the Last Payroll of the Year?

Verify Employee Information

Check each employee’s legal name, Social Security number, and address. A name or number that does not match SSA records can cause a rejected or corrected W-2. The SSA offers a free online tool, the Social Security Number Verification Service, that lets you check names and numbers against its records. Ask employees to review their information and send corrections in writing.

Collect W-9s From Contractors

Get a Form W-9 from every contractor you paid this year, so you have their name, address, and taxpayer ID before 1099 season. If a contractor has not given you one, ask for it now. Without a valid ID, you may need to apply backup withholding at 24%.

Review Taxable Fringe Benefits

Some benefits count as pay even when you do not think of them that way. Common examples include personal use of a company car, group-term life insurance over $50,000, cash and gift cards, and some bonuses. These must be added to wages and taxed. Add them before the final payroll so the taxes are withheld on time.

Decide the Timing of Year-End Pay

The pay date decides the tax year. A bonus paid on December 31 belongs to 2026, and a check dated January 2 belongs to 2027, even if the work was done in December. Make sure your bonus, commission, and final pay dates match what you tell employees.

Reconcile Payroll to Your Tax Filings

Compare your payroll register with your deposits and your Forms 941. The wages and taxes reported on all four quarters should match the totals that will appear on your W-2s. A mismatch between Form W-3 and your Forms 941 is a common reason for IRS and SSA notices.

Set Up the 2026 Form Changes

Make sure your payroll system can report the new items described below. If it did not track qualified overtime or tips from January, ask your provider how to calculate the year’s totals from your pay records before you run W-2s.

Back Up Your Records

Save your payroll registers, deduction reports, and tax filings before your system rolls into the new year.

How Do You Complete Form W-2?

A W-2 reports each employee’s wages and taxes for the year. Give copies to the employee and file copies with the SSA and any state or local agency. These are the key boxes:

• Box 1: Wages subject to federal income tax. Pre-tax 401(k) deferrals and cafeteria plan premiums reduce this amount.
• Box 2: Federal income tax withheld.
• Box 3 and Box 4: Social Security wages and tax withheld. The 2026 Social Security wage base is $184,500.
• Box 5 and Box 6: Medicare wages and tax withheld. There is no wage cap.
• Box 7: Social Security tips.
• Box 12: Letter codes for items such as 401(k) deferrals (code D) and employer health coverage cost (code DD).
• Box 13: Checkboxes for statutory employees, retirement plans, and third-party sick pay.
• Box 14a and Box 14b: Box 14a holds other information such as union dues. Box 14b is new for 2026 and holds Treasury Tipped Occupation Codes.
• Boxes 15 to 20: State and local wages and taxes.

Example: Box 1, 3, and 5

Taylor earns $60,000 in 2026. Taylor contributes $3,000 to a pre-tax 401(k) and pays $2,400 in health premiums through a cafeteria plan.

• Box 1: $60,000 – $3,000 – $2,400 = $54,600
• Box 3 and Box 5: $60,000 – $2,400 = $57,600, since 401(k) deferrals still count for Social Security and Medicare
• Box 4: 6.2% × $57,600 = $3,571.20
• Box 6: 1.45% × $57,600 = $835.20
• Box 12, code D: $3,000

What Is New on the 2026 Form W-2?

• Code TT: qualified overtime. Report the total amount of qualified overtime compensation. This is only the premium part of overtime that the Fair Labor Standards Act requires, the “half” in time and a half. Say an employee earns $20 an hour and works 100 overtime hours at $30. The premium part is $10 for each hour, so report $1,000 in Box 12 with code TT. Employees can deduct up to $12,500 ($25,000 if married filing jointly) of qualified overtime on their federal return for 2025 through 2028, subject to income limits.
• Code TP: cash tips. Report the total cash tips reported to you. Then enter the employee’s Treasury Tipped Occupation Code in Box 14b. You can enter up to two, and “000” if the occupation does not qualify.
• Code TA: Trump account contributions. Beginning July 4, 2026, employers may contribute up to $2,500 a year to the Trump account of an employee or an employee’s dependent. Report these amounts in Box 12 with code TA.
• Withholding does not change. Tips and overtime are still subject to federal income tax withholding and to the employer and employee Social Security and Medicare taxes. The new codes support the employee’s deduction on their own return.
• A higher reporting threshold. Under the 2026 rules, the level at which you must file a W-2 when no taxes are withheld rose from $600 to $2,000.

How Do You Complete Forms 1099-NEC and 1099-MISC?

Use Form 1099-NEC for payments to independent contractors for services. Form 1099-MISC covers other payments, such as rent and certain prizes.

• Threshold. For payments made after December 31, 2025, you must file when you pay a U.S. contractor $2,000 or more in the year. It was $600 before. It will be adjusted for inflation starting in 2027. Some states keep a lower threshold.
• Who gets one. Individuals, sole proprietors, and partnerships that provide services to your business. Payments to most corporations do not need a 1099, with exceptions such as attorneys.
• Card payments. Payments made by credit card, debit card, or a payment app are reported by the payment company on Form 1099-K, so you do not report them on a 1099-NEC.
• Not for employees. Workers who are really employees belong on payroll and get a W-2. If you are not sure who is who, see our guide on how to classify workers.
• New boxes. The 2026 Form 1099-NEC adds boxes for cash tips, a tipped occupation code, and qualified overtime. They apply only in rare cases where a worker is treated as a contractor for tax purposes but is an employee under wage laws.

How Do You File and Deliver the Forms?

• E-file if you file 10 or more returns. The 10-return limit counts all information return types together, so 6 W-2s and 4 1099s add up to 10.
• Use SSA Business Services Online for W-2s. You can upload files or key in forms. Paper W-2s must go with a Form W-3 summary.
• Deliver employee copies on time. You can mail them or deliver them electronically if the employee agreed to electronic delivery.
• Send former employees their copies. Mail the W-2 to the last known address. Keep for 4 years any employee copies you tried to deliver but could not.
• File state copies. Many states require W-2 and some 1099 copies, on their own schedule.

How Do You Correct a W-2 After Filing?

Use Form W-2c to correct a filed W-2 and Form W-3c to summarize the corrections. File it as soon as you find the error and give the employee a copy. If the mistake changed the Social Security or Medicare wages, you may also need to file Form 941-X.

What Are the Penalties for Missing Year-End Deadlines?

You are penalized for each form you do not file correctly and on time, and again for each copy you do not give the worker. The IRS information return penalty table shows these 2026 amounts for returns due in 2026:

• Up to 30 days late: $60 per form.
• 31 days late through August 1: $130 per form.
• After August 1 or not filed: $340 per form.
• Intentional disregard: $680 per form, with no maximum.

The amounts change each year, and small businesses have lower annual caps. As an example, 25 W-2s filed after August 1 would cost 25 × $340 = $8,500 for the IRS copies, plus another $8,500 if the employee copies are also late or missing.

Late Forms 941 and 940 carry their own failure to file, failure to pay, and failure to deposit penalties. The IRS’s new automatic penalty relief covers many of those employment tax return penalties for employers with a clean record, but it generally does not cover information returns such as W-2s and 1099s. For a full list of rates, see our guide to payroll tax penalties.

What Should You Do After You File?

• Confirm receipt. Check your SSA and IRS confirmations, and watch for rejected files.
• Ask employees to review their W-2s and tell you about mistakes right away.
• Archive everything. Keep payroll tax records for at least four years.
• Prepare for insurance audits. Your workers’ compensation carrier may audit your payroll at year-end. To understand what it looks at, read about how workers’ comp is calculated for employees.
• Plan for January. Update the Social Security wage base when the SSA announces the 2027 figure, usually in October, and refresh your state tax rates.

Use our payroll compliance checklist to turn these steps into a repeatable yearly routine. If your HR records and payroll are in separate tools, HR & payroll software that keeps names, addresses, and pay data together reduces the mismatches that cause W-2 corrections.

Do Different Industries Have Special Year-End Tasks?

• Hospitality. Tipped employees now bring new W-2 items: code TP and Box 14b occupation codes. Set up tip reporting early with payroll software for hospitality businesses, and see the guide to the best payroll software for hospitality if you need to compare tools.
• Retail. Seasonal hiring means many short-term W-2s and address changes. See retail payroll software that keeps seasonal records clean.
• Manufacturing. Overtime and shift pay drive the new code TT. Payroll software for manufacturing businesses can separate qualified overtime from other pay.
• Cannabis. Year-end deposits and W-2 accuracy matter just as much when banking is limited. Read how dispensaries handle federal taxes and use payroll software for cannabis businesses built for those limits.
• Financial services. Large year-end bonuses and commissions affect withholding and W-2 totals, and firms often mix employees with independent reps. Payroll software for financial services firms can keep each pay type and worker type separate.

Frequently Asked Questions

What if an employee says they never received their W-2?

Check the address you used and ask the employee to confirm it. Then send a replacement copy marked as reissued. If the form was undeliverable, keep it for four years. Employees can also ask the IRS for wage data if they cannot get a copy from you.

Can I deliver W-2s electronically?

Yes, but only if the employee has agreed to receive them electronically, and you must follow the notice and access rules. Without consent, mail a paper copy.

What should I do if an employee’s Social Security number is missing or wrong?

Ask the employee for their Social Security card or the correct number, and update your records. Use the SSA’s verification service to check names and numbers. Do not guess or enter placeholder numbers, and keep a record that you asked.

Do I send a 1099-NEC to a contractor I paid by credit card?

No. Payments made with a credit card, debit card, or a payment app are reported by the payment company on Form 1099-K. You only report payments made by check, cash, direct deposit, or similar methods.

Can I file W-2s late without a penalty if I have a good reason?

The penalty can be waived for reasonable cause, but you must show that you acted responsibly and that events outside your control caused the delay. The IRS’s automatic penalty relief does not generally cover W-2s and 1099s, so ask for relief in writing if you receive a notice.

Are the year-end deadlines the same in every state?

No. Many states follow the federal January dates for W-2 copies, but some set their own dates for withholding reconciliations, unemployment reports, and 1099 copies. Check each state agency’s calendar.

Conclusion

Year-end payroll comes down to accurate data, matching totals, and dates you cannot miss. Verify names and numbers, collect W-9s, reconcile your Forms 941 to your W-2 totals, and set up the new 2026 codes for overtime, tips, and Trump account contributions. File W-2s and 1099-NECs by February 1, 2027, e-file if you have 10 or more returns, and keep records for at least four years. Start in November, and you will have time to fix problems before a deadline.
