Payroll in 2026: How to Report Qualified Overtime on Your W-2 Without Getting It Wrong

Small business owner reviewing payroll reports with an accountant

If you run payroll for a small business, you’ve got a new year-end reporting responsibility to add to your checklist: reporting qualified overtime compensation on Form W-2 using Box 12, Code TT.

For tax year 2026, this reporting requirement is no longer optional. The new rule follows changes made by the One, Big, Beautiful Bill Act (OBBBA) and helps employees determine whether they may claim the federal deduction for qualified overtime compensation.

The tricky part? Code TT does NOT report total overtime wages. It generally reports only the overtime premium above the employee’s regular rate (the “half” portion of time-and-a-half overtime).

Here’s what you need to know before you close your 2026 payroll records.

What Is Qualified Overtime Compensation?

Under the 2026 General Instructions for Forms W-2 and W-3, qualified overtime is compensation paid to an individual under Section 7 of the Fair Labor Standards Act (FLSA) that exceeds the employee’s regular rate of pay.

In plain English, qualified overtime generally means the premium portion of FLSA-required overtime.

For example, imagine you pay an employee:

  • Regular rate: $20 per hour
  • FLSA overtime rate: $30 per hour (time-and-a-half)
  • Overtime hours worked: 10
  • Total overtime wages: $300

The calculation is:

  • Regular-rate portion: 10 hours × $20 = $200
  • Overtime premium: 10 hours × $10 = $100
  • Amount reported with Code TT: $100

The employee’s entire $300 of overtime pay remains wages. However, only the $100 premium portion is generally treated as qualified overtime compensation for Code TT purposes.

Important: Overtime required only by a state law, employment contract, union agreement, or employer policy isn’t automatically qualified overtime for federal Code TT reporting. You’ll need to determine whether the compensation meets the federal FLSA definition.

Action item: Review which employees received overtime that was required under the FLSA, and identify the premium portion separately from total overtime wages.

What Is New for 2026?

For tax years 2025 through 2028, eligible individuals may claim a federal deduction for qualified overtime compensation, subject to statutory limits and other requirements.

The IRS has made the employer reporting process clearer for 2026:

  • Report the total qualified overtime compensation paid during the calendar year.
  • Use Form W-2, Box 12, Code TT.
  • Report the amount for employees who received qualified overtime.
  • Continue reporting the employee’s full taxable wages in the appropriate wage boxes.
  • Do NOT reduce the Code TT amount to the employee’s potential deduction.

The deduction limit is generally up to $12,500 for an individual or $25,000 for married taxpayers filing jointly. Those limits apply when the employee prepares their income tax return. Your job as the employer is to report the qualified overtime amount accurately, not to calculate the employee’s final deduction.

As the IRS explains, the information reported on Form W-2 or Form 1099 helps the individual determine the deduction.

Action item: Confirm that your payroll provider or software has been updated for the 2026 Code TT requirement before you process year-end Forms W-2.

Where Does Code TT Go on Form W-2?

Enter Code TT in Box 12 of Form W-2, followed by the total qualified overtime compensation for the calendar year.

For example:

TT 1000.00

The 2026 Form W-2 instructions provide several formatting rules you’ll need to follow:

  • Use the capital letters TT.
  • Enter the amount with decimal points and cents.
  • Don’t use dollar signs or commas on Copy A.
  • Enter Code TT in one of the Box 12 spaces (12a through 12d).
  • Don’t place the amount in Box 14 instead of Box 12.
  • Don’t report the Code TT amount as a separate total on Form W-3.

If an employee has more than four coded items to report in Box 12, you may need to issue more than one Form W-2 for that employee (depending on the filing method and copy involved). The IRS instructions explain how to handle additional forms.

Your 2026 Forms W-2 and W-3 must generally be filed with the Social Security Administration by February 1, 2027. You must also generally furnish the employee copies by that date.

Review the IRS General Instructions for Forms W-2 and W-3 for current filing, furnishing, and e-filing requirements.

Action item: Add a Code TT review to your year-end W-2 preparation checklist, and verify that each Code TT entry appears in Box 12-not Box 14.

What Still Goes in the Regular Wage Boxes?

Code TT is additional reporting. It does not replace the employee’s regular wage reporting.

Qualified overtime compensation is generally still subject to federal income tax withholding, Social Security tax, and Medicare tax. Continue reporting the full taxable overtime wages in the applicable boxes, including:

  • Box 1: Wages, tips, and other compensation
  • Box 3: Social Security wages (subject to the wage base)
  • Box 5: Medicare wages and tips
  • Box 2, Box 4, and Box 6: Applicable federal, Social Security, and Medicare withholding

The amount reported under Code TT is not a tax-free wage exclusion. It’s an informational amount that helps the employee calculate a possible deduction on their individual return.

Do NOT subtract the Code TT amount from Box 1. Doing so could underreport wages and create inconsistencies between your Forms W-2, quarterly payroll tax returns, and payroll records.

Action item: Reconcile total overtime wages to your payroll tax reporting, then separately reconcile qualified overtime premiums to your Code TT totals.

Common Code TT Mistakes to Avoid

1. Reporting all overtime wages instead of the premium

This is likely to be the most common mistake. If you report the full $300 of time-and-a-half overtime from the example above, you’ll overstate qualified overtime. The correct Code TT amount is generally $100.

2. Treating every overtime payment as qualified

Not every premium payment meets the federal definition. Holiday pay, shift differentials, bonuses, double-time arrangements, and overtime required only by state law may require additional analysis.

For complicated compensation structures, review the employee’s regular-rate calculation and consult a qualified tax or employment-law professional.

3. Putting Code TT in Box 14

Box 14 may be used for other employee information, but Code TT belongs in Box 12. Your employee’s tax software and tax preparer may look specifically for the TT code in the correct location.

4. Omitting overtime from taxable wages

Code TT does not replace the regular wage reporting requirements. The employee’s taxable overtime generally remains included in the appropriate wage and tax boxes.

5. Using the overtime earned date instead of the payment date

Forms W-2 are generally prepared on a calendar-year, wages-paid basis. If overtime was worked in December 2026 but paid on January 1, 2027, the payment generally belongs on the 2027 Form W-2-not the 2026 form.

6. Assuming your payroll provider handled everything

A payroll service can help, but you’re still responsible for ensuring that your Forms W-2 are correct and filed on time. Confirm that the provider:

  • Tracks qualified overtime separately.
  • Uses Code TT for 2026.
  • Distinguishes FLSA overtime from other premium pay.
  • Includes the correct calendar-year totals.
  • Supports corrections through Form W-2c.

A Practical 2026 Code TT Checklist

Before you finalize your Forms W-2, complete these steps:

  1. Identify employees who received overtime during 2026.
  2. Determine whether the overtime was required under Section 7 of the FLSA.
  3. Calculate each employee’s regular rate, including applicable compensation that may affect the calculation.
  4. Separate total overtime wages from the premium above the regular rate.
  5. Reconcile the premium totals to payroll reports and supporting records.
  6. Enter the qualified overtime amount using Box 12, Code TT.
  7. Confirm that total wages remain correctly reported in Boxes 1, 3, and 5, as applicable.
  8. Review all W-2s for correct employee names, Social Security numbers, EIN information, and filing details.
  9. File with the SSA and furnish employee copies by February 1, 2027.
  10. Correct errors promptly using Form W-2c and Form W-3c when required.

Keep documentation supporting your calculations (including time records, pay rates, payroll reports, and any regular-rate analysis). That documentation can help you respond to employee questions and support your reporting position if the IRS or SSA asks for clarification.
