2026 Year-End Payroll Checklist

W-2 deadlines, 941 reconciliation, ACA reporting, and state filings -- the full year-end checklist, emailed to you.

We will only use your details to send what you requested and follow up about your payroll. No spam.

What this checklist covers

Year-end payroll is one of the highest-risk periods for employers. A missed W-2 deadline triggers IRS penalties starting at $60 per form. A 941 reconciliation error means amended returns. This checklist walks your team through every required task from October through January in the order they need to happen.

W-2 production, delivery, and SSA filing (January 31 deadline)
941 annual reconciliation against W-3 totals
Form 940 FUTA return and deposit verification
ACA 1094-C and 1095-C reporting for ALEs
State W-2 filing requirements and thresholds
Benefit election changes and new year rate updates
Taxable fringe benefit calculation and reporting
Third-party sick pay and contractor 1099-NEC preparation

If your team is spending more than a few hours on year-end payroll tasks, that is a signal. BEG managed payroll handles the full year-end process at $25-$45 PEPM, all-inclusive. No separate W-2 fee.

The Full Checklist

Year-end payroll tasks by phase

October: Pre-Close Preparation

Audit employee records for accuracy

Verify legal names, Social Security numbers, and addresses match W-4 files. SSA rejects W-2s with name/SSN mismatches.

Confirm benefit deduction rates

Check that health, dental, vision, FSA, HSA, and 401k deduction amounts match open enrollment elections for the new plan year.

Review taxable fringe benefits

Personal use of company vehicles, group-term life over $50k, and imputed income from benefits must be reported in Box 1 wages.

Audit third-party sick pay

If employees received disability payments from a carrier, request the third-party sick pay statement so wages can be included on the W-2.

November: Filing Preparation

Reconcile YTD payroll registers to 941s

Total wages reported on quarterly 941 filings should match gross wages on your YTD payroll register. Catch discrepancies now, not in January.

Verify federal tax deposit totals

Confirm all 941 tax deposits made during the year match the liability reported. IRS FTD penalty is 2% to 15% of the underpayment.

Run preliminary FUTA liability check

FUTA applies to the first $7,000 in wages per employee at 6%, reduced by state credit. Confirm your FUTA liability before filing Form 940.

Check state W-2 filing thresholds

Most states require W-2 electronic filing above 10 to 25 forms. Confirm your state threshold and electronic filing method before year-end.

December: Final Payrolls and Year-End Close

Process all bonus and supplemental payrolls

Bonus payrolls must clear before December 31 to be deductible in the current tax year. Set a cutoff date with your payroll team.

Handle retroactive pay and adjustments

Any retroactive pay increases or corrections from the current year must be paid and reported in the same calendar year they were earned.

Confirm all garnishment balances

Review child support, student loan, and IRS levy orders. Some garnishments have annual caps that require end-of-year verification.

Issue final 1099-NEC for contractors

1099-NEC is due January 31 for contractors paid $600 or more during the year. Collect or confirm W-9 information now.

January: W-2 Production and New Year Setup

Produce and distribute W-2s by January 31

IRS deadline for W-2 delivery to employees is January 31. Electronic delivery requires employee consent. Paper W-2s must be postmarked by January 31.

File W-2s with SSA electronically by January 31

Electronic W-2 filing with the Social Security Administration is required for 10 or more forms starting in 2024. Business Services Online (BSO) handles the submission.

File Form 940 (FUTA) by January 31

Annual federal unemployment tax return. If FUTA tax liability for the year exceeded $500, deposits were required quarterly. Reconcile deposits to the Form 940 before filing.

Update payroll tax rates for the new year

Social Security wage base resets January 1. SUTA rates change annually per state notice. Federal withholding tables update with the IRS Publication 15.

Reconcile ACA reporting requirements

Applicable Large Employers (50+ FTEs) must file 1094-C and 1095-C by February 28 (paper) or March 31 (electronic). Confirm ALE status and prepare 1095-C data now.
