Qualified Overtime Compensation, January 1 Paydays and Demo Cars: Year-End W-2 Answers

It’s late October, and the payroll lead at a mid-sized manufacturer has a short list taped to her monitor. First, confirm that the plant’s FLSA overtime will land in the right spot on this year’s W-2, since the IRS added a new box for it. Second, figure out what happens to the paycheck dated January 1, which is also a bank holiday. Down the road, a dealership controller is wrestling with a third question: how to run the personal use of demo cars through payroll. The first is really a question about qualified overtime compensation. All three land on the year-end W-2, and all three have clear answers from the IRS.

This guide covers what employers have to report for tax year 2026, what payroll needs to track to get there, and the two side questions that tend to show up in the same December inbox. It’s written for the people who build the W-2s, not for employees figuring out their own return.

Key takeaways

• For 2026, the overtime premium goes in box 12 with code TT. The optional box 14 approach and penalty relief applied to tax year 2025 only.
• Only the FLSA-required “half” counts. State daily overtime, contract premiums and double time beyond what federal law requires are left out.
• A paycheck dated January 1, 2027 belongs on the 2027 W-2, even if every hour on it was worked in December.
• Personal use of a demo or company vehicle is taxable wages unless it meets a specific exclusion, and you must withhold Social Security and Medicare tax on it.

What Counts as Qualified Overtime Compensation

Qualified overtime is the overtime premium that federal law requires, and nothing more. The IRS defines it as overtime pay required under section 7 of the Fair Labor Standards Act that exceeds the employee’s regular rate. In plain terms, it’s the “and-a-half” in time-and-a-half.

That narrow definition matters more than it looks. The IRS’s updated FAQs, issued in August 2026 as fact sheet FS-2026-13, spell out a few limits that trip people up:

• Exempt employees have none. Someone who isn’t eligible for FLSA overtime doesn’t receive qualified overtime, even if a union contract or company policy pays them extra for long weeks.
• Double time only counts in part. If you pay twice the regular rate, only the half-time premium needed to satisfy the FLSA qualifies.
• State and policy overtime is evaluated against the FLSA. Pay for hours over 8 in a day, over 35 in a week, or on a holiday isn’t automatically qualified. You have to work out what the FLSA itself would have required for that workweek.
• Some industries use alternative methods. Hospitals and certain residential care facilities that use the FLSA’s alternative overtime calculation use the premium actually paid under that method.

The IRS example is useful to keep handy. An employee earning $20 an hour works 50 hours and the employer pays double time for the 10 extra hours, $400 in total. The FLSA only required $300 for those hours. So the qualified amount is $100, the required half-time premium, not $200 and not $400.

2025 vs. 2026: What Changed on Form W-2

For tax year 2025, the IRS gave employers a pass. Notice 2025-62, announced in IRS news release IR-2025-110, waived penalties for not separately reporting the overtime premium. Employers were encouraged, not required, to share the figure through box 14, an online portal or a separate statement.

That relief is over. Starting with tax year 2026, the requirement is firm:

• Report the total in box 12, code TT. The 2026 General Instructions for Forms W-2 and W-3 add code TT for the total qualified overtime paid during the year.
• Report the full amount, not the deductible amount. If an employee earned $30,000 of qualified overtime, the IRS says box 12 shows $30,000, even though the employee’s deduction caps at $12,500 ($25,000 on a joint return).
• Employees can only deduct what you report. For tax years after 2025, an amount missing from code TT can’t be claimed. An employee who thinks you understated it has to ask you for a corrected form.
• Errors mean a W-2c. If you find a mistake in code TT (one of several year-end payroll mistakes that turn into a W-2c), you file Form W-2c with the SSA and furnish it to the employee as soon as possible. Information return penalties can apply.

The deadline doesn’t move, either. Copies of the 2026 W-2 go to employees, and Copy A goes to the SSA, by February 1, 2027.

One more thing employees will ask about. Overtime is still subject to federal income tax withholding, Social Security and Medicare. You don’t reduce withholding on your own. An employee who wants less withheld can turn in a new Form W-4, which was updated for 2026 so employees can estimate the deduction in Step 4(b).

What Payroll Needs to Track for Each Employee

Here’s the reality: you can’t pull this number out of a gross-pay report in January. The IRS says the amount is generally figured workweek by workweek, using this formula for most employees:

• FLSA hours worked over 40 in the workweek
• multiplied by one-half
• multiplied by the employee’s FLSA regular rate for that workweek

Simple enough on paper. The regular rate is where it gets messy. Under the FLSA, it includes all pay for the workweek, whether it comes from hourly wages, piece rate, salary or commission, minus a few statutory exclusions, divided by hours actually worked. A nondiscretionary production bonus or a shift differential raises the regular rate, which raises the premium.

So for each FLSA-eligible employee, payroll should be able to show:

• The workweek definition you use (any fixed, recurring 168-hour period, set by the employer)
• Hours worked per workweek, including any time worked across two pay rates or departments
• Every earning that feeds the regular rate, with the workweek it belongs to
• The premium portion paid, kept separate from straight-time pay for overtime hours
• Any overtime paid under state law, a union contract or company policy that goes beyond the FLSA, flagged so it’s left out of code TT
• Exempt or nonexempt status, current as of each workweek

Think about a plant that pays daily overtime after 8 hours because of a labor agreement. Someone works four 10-hour days. That’s 8 hours of contract overtime and zero hours over 40. The qualified amount for that week is zero. If your overtime earning code doesn’t know the difference, your W-2 will overstate it, and the IRS says employees can’t use an overstated amount anyway.

Which Year’s W-2 Does a January 1 Paycheck Belong On?

It belongs on the year it’s paid. That’s the short answer, and the IRS uses almost this exact scenario in its W-2 instructions.

Form W-2 is based on wages paid during the calendar year, not wages earned. The IRS example: an employee works December 13 through December 26, 2026, and those wages are paid on January 1, 2027. Those wages go on the 2027 Form W-2. The same timing principle applies to qualified overtime, according to the August 2026 FAQs.

January 1, 2027 falls on a Friday and it’s a bank holiday, so plenty of employers will move that pay date. Here’s the catch. If you pay on Thursday, December 31 instead, those wages are paid in 2026 and land on the 2026 W-2. That changes year-to-date totals, Social Security wage base math for high earners, and any annual limits tied to the calendar year.

Neither choice is wrong. What hurts is deciding late. Pick the date, tell employees which W-2 the check will appear on, and lock it into the payroll calendar before the year-end rollover. Our year-end payroll checklist walks through the rest of the timeline.

Demo Cars and Other Fringe Benefits

Dealerships run into this one every year. When an employee drives a company vehicle for personal use, the value of that use is generally taxable wages. It goes in boxes 1, 3 and 5 of the W-2, and you have to withhold Social Security and Medicare tax on it.

There is an exception that matters on the sales floor. Under IRS Publication 15-B, use of a demonstrator car by a full-time auto salesperson, in the sales area where the sales office is located, generally qualifies as a working condition fringe and isn’t taxed. That only works if the use is mainly to help them sell and there are substantial restrictions on personal use. The IRS points to Revenue Procedure 2001-56 for simplified methods to decide whether full, partial or no exclusion applies. Service advisors, office staff and managers driving demos usually don’t fit that exception.

A few rules make year-end easier:

• You can elect not to withhold federal income tax on vehicle use. You still withhold Social Security and Medicare. You must notify the employee in writing by January 31 of the election year (or within 30 days of first providing the vehicle) and include the value in boxes 1, 3, 5 and 14a.
• You can treat noncash fringe benefits as paid less often than every payroll, as long as it’s at least once a year.
• The special accounting rule lets you push November and December use into the next year. If you use it, you must use it for everyone who gets that benefit and tell affected employees.
• Values must be final by January 31 of the following year so the W-2 and Form 941 match.

Small detail, but the 2026 W-2 split box 14 into 14a and 14b. Other items that used to go in box 14 now go in 14a.

Where Netchex Fits

None of this is hard once the data is clean. It’s hard when overtime, bonuses and demo use live in three places and someone reconstructs them in January.

Netchex calculates weighted overtime automatically for employees who work more than one rate in a pay period, so the blended regular rate isn’t averaged by hand. When you add a nondiscretionary bonus, Netchex reviews the underlying time cards for overtime premiums so the bonus factors into overtime pay correctly. Payroll Comparison lets you put runs side by side, including overtime, to catch a jump before it’s submitted. And OneScreen Payroll surfaces missing punches, unapproved timecards and other gaps before a run goes out, which is where most overtime errors start.

At year-end, admins can close the year themselves. The rollover checks for pending payrolls and unprocessed on-demand or voided checks before it lets you submit. For dealerships, Netchex pulls tech time and commission data from Dealertrack, and our support team is trained on flat-rate pay, draws and DMS environments. If you want to confirm how your overtime and fringe earning codes map to the 2026 W-2, your dedicated account manager is the person to ask.
