Night Call Adds Up
Lab call is typically 1.5× after 40, and short-staffed labs run techs past 40 most weeks they carry the pager.
- • Call-in hours past 40/week at 1.5× → deductible premium
- • Weekend draws and stat call-backs past 40 → deductible
- • Straight-time extra shifts under 40 total hours → not OT
Worked Example
A single MLT at $29/hour, 180 OT hours of call-in.
- • Premium $14.50 × 180 → $2,610 deduction, $313 savings at 12%

Frequently Asked Questions
Do lab techs qualify for the OBBBA overtime deduction?
Yes, when paid hourly on W-2. Hours beyond 40/week at time-and-a-half generate deductible premium up to the caps.
What about call-in minimums (2-hour minimums)?
Hours paid count toward the 40-hour threshold whether you worked 20 minutes or 2 hours. Track paid hours, not time on site.
