Rush Seasons Create the Premium
ITC-deadline and net-metering-change rushes put installers on 55-hour weeks for months. Those premium dollars are deductible.
- • Install hours past 40/week at 1.5× → deductible premium
- • Weekend commissioning pushes → same
- • Cash side jobs → not W-2 wages, no deduction here
Worked Example
Single installer, $24/hour, 320 OT hours.
- • Premium $12 × 320 → $3,840, saving $461 at 12%

Frequently Asked Questions
Do solar installers qualify for the OBBBA overtime deduction?
Yes when on W-2 payroll with OT past 40 hours at time-and-a-half. 1099 subcontractor crews do not — the deduction is W-2 only.
Does the solar tax credit interact with this?
No. The homeowner's ITC is unrelated to your wage deduction. Your deduction is purely the OT premium on your W-2.
