2026 Year-End Payroll Checklist: Deadlines and New W-2 Codes

Key Takeaways

• Year-end payroll closes on February 1, 2027, for 2026 wages, the due date for Forms W-2 and W-3, Form 940, and the fourth-quarter Form 941, because January 31 falls on a Sunday.
• The 2026 Form W-2 adds three fields: box 12 code TP for cash tips, code TT for qualified overtime, and box 14b for tipped occupation codes.
• The Social Security wage base rises from $184,500 in 2026 to $192,300 in 2027.
• Biweekly Friday payrolls face 27 pay dates in 2027 unless the January 1 payday moves into 2026.
• Würk’s tax team prepares quarter-end and end-of-year payroll tax filings for clients, and managed services can audit them with you.

Year-End Payroll Deadlines for 2026

Year-end payroll for 2026 turns on one rule: wages belong to the tax year in which they are paid, not the year in which they are earned. A December 28 to January 10 pay period paid on January 15 is 2027 income, even though most of the work happened in December.

The federal year-end deadlines land almost all at once. Filings normally due January 31 move to Monday, February 1, because the 31st falls on a Sunday in 2027.

Date	Deadline
December 31, 2026	Final payroll of the year, and the last pay date counted in the 2026 tax year
January 1, 2027	The $192,300 Social Security wage base takes effect, along with new state minimum wages
February 1, 2027	Forms W-2 furnished to employees and filed with the SSA, with Form W-3
February 1, 2027	Fourth-quarter Form 941 and annual Form 940 due
February 1, 2027	Forms 1099-NEC furnished to contractors and filed with the IRS

The W-2 instructions set February 1, 2027 as the date for both the SSA filing and employee copies. Publication 15 lists the quarterly and annual returns as due by January 31, and its weekend rule pushes both to the next business day. If you deposited all tax payments on time, you get until February 10 for those two returns. The Social Security Administration set the 2027 wage base at $192,300, up from $184,500 for 2026.

State payroll requirements vary. Most states want an annual reconciliation of state income tax withholding in late winter, and new state minimum wages take effect the first day of the year. Michigan’s minimum, for example, rises to $15.00 an hour on January 1, 2027, according to the DOL’s state minimum wage tracker.

What Changed on the 2026 Form W-2

The 2026 Form W-2, the Wage and Tax Statement, adds reporting for qualified tips and qualified overtime, the two deductions created by the One Big Beautiful Bill Act. Under the new tax reporting requirements, employers report both separately starting with 2026 wages.

• Box 12, code TP: the total cash tips the employee reported to you, per the Form W-2 instructions.
• Box 12, code TT: the total qualified overtime compensation you paid.
• Box 14b: the Treasury Tipped Occupation Code for each tipped employee. Everything that used to go in box 14 now goes in box 14a.

These fields exist because employees can now deduct up to $25,000 of qualified tips, and $12,500 of qualified overtime or $25,000 filing jointly, according to IRS Publication 15. The deductions happen on the employee’s federal income tax return. Your payroll tax obligations stay the same: tips and overtime remain subject to Social Security tax and Medicare.

The harder part is the payroll data. Code TT needs the overtime premium, the half in time-and-a-half, tracked apart from straight-time pay in every pay period. Payroll software that stores only total overtime dollars leaves you splitting numbers by hand in January. Time and labor tracking that syncs to your payroll system keeps the premium visible all year.

Not every overtime dollar qualifies. Overtime paid under a state daily rule or a collective bargaining agreement, beyond what the federal Fair Labor Standards Act, or FLSA, requires, falls outside code TT. Tipped staff at beverage businesses and overtime-heavy casino floors will feel this most. For the law behind the codes, read this breakdown of the One Big Beautiful Bill Act.

The 2026 Year-End Payroll Checklist

A year-end payroll checklist covers what has to be right before your final 2026 payroll and what has to be ready before the first 2027 payroll run. Most common year-end payroll mistakes trace back to a skipped step, so work through this 2026 payroll year-end checklist in order. It works as a year-end payroll checklist for small businesses and a checklist for employers with several locations.

1. Employee records. Match each employee’s legal name, Social Security number, and address against SSA records before year-end tax forms print. A name and number that don’t match can draw a penalty notice.
2. Taxable fringe benefits. Add personal use of company vehicles, group-term life coverage over $50,000, and gift cards to wages. Publication 15-B says cash and cash-equivalent benefits are never excludable, no matter how small.
3. The special accounting rule. Benefits provided in November and December may be treated as paid in the following year, according to the IRS fringe benefit guide. You don’t have to notify the IRS that you use it.
4. Bonuses and off-cycle checks. Withhold 22% on supplemental wages such as a year-end bonus, or 37% on the amount above $1 million for any employee past that mark, as Publication 15 explains.
5. Wage base caps. Confirm Social Security withholding stopped for every employee past $184,500 in 2026 wages.
6. Benefits deductions. Reconcile Section 125, HSA, and retirement deferrals against plan records, and confirm the box 12 code DD amount for employer health coverage. Benefits administration that feeds deductions straight to payroll removes most of this step.
7. Tips and overtime totals. Pull year-to-date reported tips for code TP and qualified overtime premium for code TT.
8. Contractor payments. Total payments to each contractor. For 2026, the 1099-NEC threshold rises from $600 to $2,000, per the IRS 1099-NEC instructions, so contractors paid less than that no longer need a form.
9. 2027 setup. Load the new tax rates and wage bases, state minimum wages, SUI rate notices, and new Forms W-4 from employees who changed withholding. Confirm your deposit schedule too: under IRS Notice 931, more than $50,000 of employment tax from July 2025 through June 2026 makes you a semiweekly depositor for 2027.

Process your final payroll for the year only after steps one through eight are clear.

How to Reconcile Payroll at Year End

To reconcile payroll at year end, prove that what you reported each quarter matches your annual payroll forms. The work starts immediately after the final payroll run and ends before your tax filing deadlines, and the IRS checks the same math on its side.

Form 941 Totals Against Form W-3

The IRS matches the tax information on your four quarterly Forms 941 against the totals on Form W-3: wages, tips, and withholding. A gap between them usually ends in a letter.

Mismatches tend to come from three places:

• Off-cycle checks run outside the normal payroll calendar
• Voided or manual checks never entered in the ledger
• Prior-period adjustments posted to the wrong quarter

For managed payroll clients, Würk’s payroll specialists can audit this tie-out with you as part of year-end payroll preparation.

State Withholding and Unemployment

Each state you withhold in needs its own annual reconciliation, and each state unemployment account needs a final wage report. Those totals should tie to the state boxes on employees’ Forms W-2. Each state account also carries its own tax rate, so confirm it against the state’s notice. Federal unemployment tax belongs on Form 940, and the credit against it depends on your state payments arriving on time.

Employees who moved or worked in two places during 2026 need a second look. Their wages should be allocated to where the work happened, and the split has to agree on every return it touches. The guide to multi-state payroll covers how allocation works.

Year-End Payroll Reports

Three reports do most of the reconciliation:

• Payroll register: every check for the year, by employee and pay date.
• Tax liability report: taxes withheld and owed by jurisdiction and quarter.
• Year-to-date earnings and deductions: the figures each W-2 is built from.

Have someone other than the person who ran payroll review your payroll records. Splitting payroll tasks this way is a basic internal control. A short payroll audit checklist gives that reviewer a set of controls to test.

Is 2027 a 27-Pay-Period Year?

Yes, if you run a biweekly Friday payroll schedule that pays on January 1. January 1, 2027 is a Friday, so that schedule hits 27 pay dates in 2027, with the last payroll on December 31. Weekly schedules on the same day hit 53.

January 1 is also a bank holiday. If your bank won’t process that day, you’ll likely move the payday to Thursday, December 31, 2026, and under the tax-year rule those wages then count in 2026. That brings 2027 back to 26 pay dates and gives 2026 a 27th, so model both years before you decide.

The extra pay date ripples into three places:

• Salaried pay: dividing an annual salary by 27 instead of 26 shrinks each check. Keep the per-check amount instead, and salaried staff earn an extra paycheck for the year.
• Benefit deductions: per-paycheck deductions set for 26 pays will over-collect on a 27th check unless you skip or adjust them.
• Budgets: annual payroll forecasts built on 26 pay dates run one cycle short.

Corrections and Late Filing Penalties

Errors found after filing are fixed on Form W-2c, sent with Form W-3c when you file on paper, according to IRS Topic 752. Penalties scale with how long an error stands, so speed matters.

Employers filing 10 or more information returns, counting W-2s and 1099s together, must file electronically. You can file Form 8809 to request one extension of time, and the IRS grants it only in extraordinary circumstances.

Each late or wrong form carries its own penalty. The most recent IRS penalty schedule covers returns due in 2026:

When the correct form is filed	Penalty per form
Within 30 days of the due date	$60
After 30 days, by August 1	$130
After August 1, or never	$340
Intentional disregard	$680, with no cap

The IRS hadn’t posted amounts for returns due in 2027 as of October 2026.
