An overtime premium is the extra amount an employer pays above the straight-time rate for hours worked beyond the maximum workweek the Fair Labor Standards Act sets. It is the half in time and one half, which makes it one part of overtime pay rather than the whole of it: the straight-time earnings for those same hours are the other part. The premium is computed on the workweek’s regular rate, which is derived from total remuneration rather than quoted from the employment agreement, and that derivation is set out in gross wages.
Overtime Premium and Overtime Pay Are Not the Same Number
Overtime pay is the whole of what an employee receives for the hours beyond the threshold. The overtime premium is only the part of it sitting above the straight-time rate. The statute is what blends the two, because it fixes a rate for the hour rather than an amount on top of one: no employer may employ a covered employee for a workweek longer than forty hours unless the employee receives compensation for his employment in excess of the hours specified at a rate not less than one and one-half times the regular rate at which he is employed (29 U.S.C. 207(a)(1)).
Payroll records keep the two apart on purpose. An employer must record total daily or weekly straight-time earnings or wages due for hours worked during the workday or workweek, exclusive of premium overtime compensation, and then record as its own item the total premium pay for overtime hours, an amount that excludes the straight-time earnings already recorded (eCFR, section 516.2(a)(8) and (a)(9), Items required).
A Worked Example on One Workweek
Say a non-exempt employee, one the Act’s overtime requirement covers, works the hours below at a flat hourly rate with no bonus or other remuneration in the week, so the regular rate equals the stated rate.
INPUTS
Hours worked in the workweek 45
Stated hourly rate 28.00
THE PAYROLL REGISTER SPLIT
Straight-time earnings 45 x 28.00 1,260.00
Overtime hours 45 - 40 5
Half-time increment 28.00 / 2 14.00
Overtime premium 5 x 14.00 70.00
Total wages for the week 1,260.00 + 70.00 1,330.00
THE SAME WEEK, STATED AS OVERTIME PAY
Time and one-half rate 28.00 x 1.5 42.00
Overtime pay for 5 hours 5 x 42.00 210.00
of which straight time 5 x 28.00 140.00
of which premium 5 x 14.00 70.00Both readings describe the same week. Overtime pay names everything the employee received for the five excess hours. The overtime premium names only the half sitting inside that, so a payroll reporting overtime pay where a form asks for the overtime premium overstates by the straight-time portion of those same hours.
What Qualifies as an Overtime Premium
Three kinds of extra compensation qualify, and the statute names each by the reason for the premium rather than by what payroll calls it. The first is extra compensation provided by a premium rate for certain hours worked because those hours are in excess of eight in a day, in excess of the maximum workweek that applies to the employee, or in excess of that employee’s normal or regular working hours (29 U.S.C. 207(e)(5)).
The second is a premium rate paid for work on Saturdays, Sundays, holidays or regular days of rest, or on the sixth or seventh day of the workweek, and it qualifies only where that rate is not less than one and one-half times the rate established in good faith for like work performed in nonovertime hours on other days (29 U.S.C. 207(e)(6)).
The third is a premium rate paid under an employment contract or collective-bargaining agreement for work outside the hours that agreement establishes in good faith as the basic, normal or regular workday or workweek, and it qualifies only where that rate is not less than one and one-half times the rate the agreement establishes in good faith for like work performed during that workday or workweek (29 U.S.C. 207(e)(7)).
Qualifying does two things at once. Extra compensation of those three kinds stays out of the regular rate under the subsection that names them, so it does not inflate the base the statutory premium is then computed on, and it is separately made creditable toward the overtime compensation the Act requires (29 U.S.C. 207(h)(2)). Nothing else is creditable, and the regulation says so in terms: no other types of remuneration for employment may be so credited (eCFR, section 778.201(c), Overtime premiums, general).
What Does Not Qualify, Even When It Looks Like One
A lump sum fails, however generous it is. A premium paid as a lump sum for work performed during overtime hours, without regard to the number of overtime hours worked, does not qualify even where the money equals or exceeds what an hourly computation would have produced, and the regulation works the case with a flat sum of $75 for Sunday work paid to an employee whose straight-time rate is $5 an hour and who always works less than 10 hours on Sunday (eCFR, section 778.310, Fixed sum for varying amounts of overtime). A payment that fails goes into the regular rate, which raises the base every genuine premium is measured against, and none of it can be credited against what the Act already required.
Premiums paid for something other than the timing of the work fail for the same reason. Nightshift differentials, whether they take the form of a percent of the base rate or an addition of so many cents per hour, and premiums paid for hazardous, arduous or dirty work, must be included in the regular rate (eCFR, section 778.207(b), Other types of contract premium pay distinguished).
Where the Premium Sits in a Firm’s Work
Inside a CPA firm the premium reaches the back office rather than the professional staff, because the learned professional exemption generally covers certified public accountants and generally does not cover accounting clerks and bookkeepers doing routine work. Both halves of that test, the salary level and the duties, are worked through in in-house versus outsourced accounting.
On a client’s job-costed books the premium poses a question straight time never does. The straight-time hours are direct labor on whatever job consumed them. The premium is harder to place, because the job being worked in the forty-first hour did not cause it; the week’s schedule did, and a different job could as easily have been the one that ran into overtime. Charging the premium to the job that happened to run late prices two identical jobs differently, which is the argument for sending it to an overhead pool and letting it fall across the work that caused the crowding, using the machinery set out in costing overheads.
That book choice does not carry over to the return by itself. Section 263A counts overtime pay as an element of direct labor cost rather than as burden, a list already worked through for job costing in construction bookkeeping. What the regulation adds for this question is a tolerance: a taxpayer is not treated as using an erroneous method of accounting if direct labor costs are treated as indirect costs under its allocation method, provided those costs are capitalized to the extent required (Treasury Regulation 1.263A-1(g)(2)).
Where the Premium Surfaces on a Pay Stub and a Form W-2
What Is OT Premium on a Pay Stub?
It is the separately recorded premium: the extra half for the overtime hours, not the pay for those hours. A stub carrying an OT premium line alongside a regular earnings line is showing the split the payroll recordkeeping regulation requires an employer to keep (eCFR, section 516.2(a)(9), Items required), so the two lines read together, and not the premium line on its own, are what the employee earned for the week.
What Does Overtime Premium Mean on My W-2?
On the 2026 Form W-2 it means box 12, code TT. Qualified overtime is compensation paid to an individual required under section 7 of the Fair Labor Standards Act of 1938 that is more than the regular rate at which the individual is employed, and the instructions say it directly: only the half portion of time-and-a-half compensation would be reported using code TT (IRS, General Instructions for Forms W-2 and W-3). The statutory hook matches: the wage statement must show the total amount of qualified overtime compensation (26 U.S.C. 6051(a)(19)), a term defined as overtime compensation required under section 7 of that Act in excess of the regular rate at which the individual is employed (26 U.S.C. 225(c)(1)).
That box is a reporting line, not an exclusion. Overtime compensation is still generally subject to federal income tax withholding and to both the employer share and the employee share of social security tax and Medicare tax (IRS, General Instructions for Forms W-2 and W-3), the charges set out in payroll tax. The deduction that reporting feeds, its ceilings and phase-outs and the transition year before the box existed, is covered in what the One Big Beautiful Bill changed for accounting firms.
Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, and a firm can put a real block of its own payroll and close work through a trial task before any client file depends on it.
