No Tax on Overtime Calculator for Machinists
Machinists and CNC operators are critical to American manufacturing — and overtime is common during production runs, rush orders, and maintenance shutdowns. Under the OBBBA 2026 overtime tax deduction, you may deduct the FLSA overtime premium (typically ½ × regular rate × OT hours) on Schedule 1-A — up to $12,500 ($25,000 joint) for tax years 2025–2028 — not your full overtime paycheck.

Tax Notes for Machinists
- Machinists and CNC operators covered by the FLSA earn 1.5× for hours over 40 per week — the FLSA overtime premium may qualify for a Schedule 1-A deduction under the OBBBA (cap $12,500 / $25,000 joint).
- FICA taxes (6.2% Social Security + 1.45% Medicare) still apply to overtime earnings — the deduction covers federal income tax only.
- Rush orders, production deadlines, and equipment maintenance shutdowns often require significant overtime — all qualifying hours beyond 40 per week are deductible (caps and income limits apply).
- The deduction applies to W-2 employees in machine shops, manufacturing plants, and aerospace/defense facilities.
Three Calculation Examples for Machinists
Moderate OT — CNC Operator
A CNC operator working 8 hours of overtime per week at 1.5× rate ($33/hr OT). Gross OT pay: $13,200 · Qualified premium ≈ $4,400 (Schedule 1-A; cap $12,500 single / $25,000 joint — not full OT exempt).
Regular OT — Machinist
A machinist working 10 hours of overtime per week at 1.5× rate ($39/hr OT). Annual overtime pay: $19,500 — saving approximately $4,290 at the 22% bracket.
Heavy OT — Senior Machinist/Setup
A senior machinist or setup technician working 15 hours of overtime per week at 1.5× rate ($48/hr OT). Annual overtime pay: $36,000 — over $7,900 in federal tax savings.
Frequently Asked Questions
Does my machinist overtime qualify for the OBBBA deduction?
Qualified overtime compensation from overtime hours worked beyond 40 per week by W-2 machinists and CNC operators may be deducted on Schedule 1-A (FLSA premium only, subject to the $12,500 / $25,000 cap) — not a blanket deduction of full OT wages. This includes manual machinists, CNC operators, CNC programmers, and setup technicians employed at machine shops or manufacturing facilities.
What about double-time pay for weekend production runs?
Double-time pay (2×) for weekend or holiday production qualifies as overtime compensation under the OBBBA if the hours exceed 40 in the workweek. Many machine shops offer premium weekend rates — usually only the FLSA half-premium is deductible on Schedule 1-A.
Does shutdown maintenance overtime qualify?
Yes. Overtime worked during scheduled plant shutdowns, equipment overhauls, or emergency maintenance qualifies for the deduction as long as total hours exceed 40 per week and you are paid at overtime rates.
I work second or third shift with a differential — is that overtime?
Shift differentials alone are not overtime. A higher hourly rate for working nights or weekends does not qualify as overtime under the FLSA. Only hours worked beyond 40 per week that are paid at the overtime premium rate (1.5× or higher) qualify for the OBBBA deduction.
