200-Amp Main Electrical Panel Upgrade Tax Credit: IRC Section 25C ($600) vs Section 25D (30%) Rules
Upgrading an obsolete 100-Amp Zinsco, Federal Pacific, or crowded 125-Amp breaker box to a modern 200-Amp service panel costs $2,500 to $4,800. Depending on whether you install the panel with solar/battery storage or with a heat pump, two different IRS tax code sections apply!
📋 Official IRS Line-by-Line & Statutory Breakdown
When a main panel upgrade, subpanel, or Smart Load Center (like a Span Panel or EcoFlow Smart Home Panel 2) is installed as an integral part of interconnecting your new solar array or >=3 kWh home battery, it is claimed under Form 5695 Part I (Section 25D) at the full uncapped 30% rate!
If you are NOT installing solar or a battery, you can still claim 30% of a panelboard upgrade (up to a $600 cap) under Form 5695 Part II (Section 25C Energy Efficient Home Improvement Credit), provided the new panel has a load capacity of at least 200 Amps and enables another qualified energy efficiency property.
Before paying $4,500 to trench and replace a 100A/125A main panel, ask your electrician about: (1) Derating the Main Breaker from 100A to 80A under the NEC 705.12(B)(3)(2) 120% Busbar Rule, (2) Line-Side Tap interconnection ahead of the main breaker, or (3) PCS Software Current Limiting (Enphase Power Control / Tesla Dynamic Export Limit).
🚨 IRS Compliance & Audit Red Flags
- ⚠️You cannot double-claim the exact same $3,500 panel upgrade invoice on both Part I (Section 25D) and Part II (Section 25C) of Form 5695.
- ⚠️Under Section 25C (Part II), the panel must meet National Electrical Code requirements and have a minimum rating of 200 Amps.
