Morning: Small Business Tax Tips (New Haven): Year-End Payroll and W-2 Prep — What New Haven Employers Must File Before January 31, 2027

New Haven, Connecticut — Jose’s Tax Service — September 23, 2026

New Haven small business owners with employees should review year-end payroll compliance now. Do not wait until January. Reconcile payroll records, verify employee information, review taxable fringe benefits, and calendar every federal and Connecticut filing deadline before year-end closes.

Accurate payroll reporting protects employee refunds, reduces correction work, and supports clean business tax reporting. Incorrect or late filings may lead to penalties, notices, and delayed processing.

Reconcile Payroll Returns Before Year-End!

Match your payroll records to the general ledger before the books close.

Reconcile these records now:

1. Payroll registers.
2. Quarterly payroll tax returns.
3. Federal tax deposits.
4. Connecticut withholding payments.
5. Employer benefit and fringe benefit records.
6. Year-end wage expense accounts in the general ledger.

Focus on federal quarter-end reporting first:

• Form 941, Employer’s QUARTERLY Federal Tax Return for the fourth quarter is due January 31, 2027.
• Form 940, Employer’s Annual Federal Unemployment (FUTA) Tax Return is due January 31, 2027, or February 10, 2027 if all federal unemployment tax deposits were made on time.

Do not carry unresolved variances into January. Investigate differences in taxable wages, federal income tax withholding, Social Security tax, Medicare tax, and employer payroll tax expense now.

Reminder: Reconcile Q4 payroll records before preparing Forms W-2, W-3, 941, and 940. Unresolved differences can delay filing and may lead to amended returns.

Prepare Form W-2 and Form W-3 Now!

Furnish wage statements to employees on time. File the transmittal with the Social Security Administration (SSA) on time.

Use these year-end rules:

• Furnish Form W-2, Wage and Tax Statement to each employee by January 31, 2027.
• File Form W-2 with Form W-3, Transmittal of Wage and Tax Statements by January 31, 2027.
• Connecticut employers should also file Form CT-W3, Connecticut Annual Reconciliation of Withholding, with state copies of Forms W-2 to the Connecticut Department of Revenue Services (DRS) by January 31, 2027.

Do not treat W-2 preparation as a last-week task. Start with payroll reconciliation, employee data verification, fringe benefit review, and third-party payroll coordination.

Incorrect or late Forms W-2 may lead to penalties under IRC §6721 and IRC §6722. They can also delay employee refunds.

Reminder: File and furnish by January 31, 2027. Corrections on Form W-2c, Corrected Wage and Tax Statement create additional processing time and administrative work.

Follow Connecticut Withholding Rules Through myconneCT!

Connecticut payroll compliance requires separate state review.

Employers should confirm these Connecticut procedures:

• File Form CT-941, Connecticut Quarterly Reconciliation of Withholding quarterly.
• File each Form CT-941 by the last day of the month following the close of the quarter.
• Submit all Connecticut withholding payments and returns electronically through myconneCT.
• Confirm that your Connecticut withholding frequency in myconneCT is current: weekly, monthly, or quarterly.

Do not assume your deposit schedule remained unchanged from a prior year. Review the account profile in myconneCT and confirm current payment frequency before the next due date.

For unemployment tax planning, Connecticut employers should also note:

• The 2026 Connecticut unemployment insurance taxable wage base is $27,000.
• The 2026 new employer unemployment insurance rate is 1.90%.

Reminder: Connecticut withholding and unemployment obligations are separate compliance tracks. Review both before year-end and confirm that filings, payments, and registrations are current.

Verify Employee Data Before You Issue Forms W-2!

Employee master data should be reviewed now. Errors in names, Social Security numbers, and withholding certificates commonly create avoidable year-end corrections.

Verify each of these items:

1. Legal name exactly as it appears in Social Security Administration records.
2. Social Security number (SSN) for accuracy.
3. Current Form W-4, Employee’s Withholding Certificate on file.
4. Current Form CT-W4, Employee’s Withholding or Exemption Certificate on file.
5. Current address for employee statement delivery.
6. Final 2026 wage and withholding totals in the payroll system.

Use a formal employee verification process. Require updates before final payroll is processed for the year.

Incorrect employee data may require filing Form W-2c and may lead to penalties. It can also delay employee refund processing.

Reminder: Match names to Social Security Administration records before Forms W-2 are issued. Do not rely on informal nicknames, prior payroll imports, or incomplete onboarding records.

Review Fringe Benefits and Taxable Wages!

Year-end payroll review should include taxable fringe benefits. Not every benefit is excluded from wages.

Review these items carefully:

• Employer-provided health coverage reporting requirements.
• Employer-provided vehicles and personal-use calculations.
• Gift cards.
• Bonuses.
• Employee achievement awards.

Determine what must be included in taxable wages for federal and Connecticut payroll reporting. Some items are fully taxable. Some may be partially taxable. Some may require special valuation or substantiation.

Coordinate benefit reporting with your payroll provider before the final payroll run of the year. Late adjustments can create W-2 errors and amended filings.

Reminder: Review fringe benefits before closing December payroll. Once Forms W-2 are issued, corrections become more expensive and time-consuming.

Coordinate Third-Party Sick Pay and Paid Leave Reporting!

Third-party payroll issues should be addressed before year-end forms are finalized.

Review these areas:

• Third-party sick pay reporting responsibilities.
• Paid family and medical leave coordination.
• Payroll provider year-end reporting schedules.
• Tax deposit timing for special wage items.
• Responsibility for W-2 preparation when third-party payments were involved.

Do not assume the payroll company, benefits administrator, and employer records all match automatically. Compare reports and assign responsibility for each filing and employee statement.

Reminder: Confirm reporting responsibility in writing with your payroll provider and any third-party payor before January filing begins.

Report New Hires and Confirm Labor Registration!

Connecticut employers must complete separate labor reporting obligations.

Take these actions:

1. Report new hires to the Connecticut Department of Labor within 14 days of the hire date when reporting online.
2. Report new hires within 20 days if reporting by fax or mail.
3. Register separately with the Connecticut Department of Labor for unemployment insurance taxes.

Do not assume a tax registration with the Connecticut Department of Revenue Services also completes labor registration. Separate agency compliance is required.

Reminder: Review onboarding procedures now. Delayed new-hire reporting and missing unemployment registration can create state compliance issues.

Watch the Penalty Exposure!

Year-end payroll reporting errors can create direct financial exposure.

Late or incorrect filings may lead to:

• Penalties under IRC §6721 for incorrect information returns.
• Penalties under IRC §6722 for incorrect payee statements.
• Delayed employee refunds.
• Additional payroll provider fees for corrections.
• Processing delays when amended Form W-2c filings are required.

Use current payroll reports, employee verification procedures, and year-end reconciliation workpapers to reduce preventable errors.

Reminder: Correcting payroll forms after filing is possible, but it is inefficient. File accurately the first time whenever possible.

Use This December Year-End Payroll Checklist!

Complete these actions before December closes:

1. Reconcile payroll registers to the general ledger, federal deposits, Connecticut withholding payments, and prior quarterly returns.
2. Verify employee information including legal names, Social Security numbers, addresses, Form W-4, and Form CT-W4.
3. Review fringe benefits including health coverage reporting, vehicles, gift cards, bonuses, and employee achievement awards.
4. Confirm deposit schedules in EFTPS and myconneCT, and verify that your Connecticut withholding frequency is current.
5. Calendar all January 31 deadlines for Form 941, Form 940, Form W-2, Form W-3, and Form CT-W3.
6. Schedule a year-end payroll review with your tax professional and payroll provider before final forms are issued.

Close the year with complete records. File on time. Correct issues before January.
